When the static was read before `UiThread.Initialize()` completed, the property returned `null` and the consumer threw a `NullReferenceException` that named neither the missing initialisation nor the responsible component. + +The failure was non-deterministic and order-dependent: it was observed once during a full-suite MSTest run under `[assembly: Parallelize(Workers = 0, Scope = ExecutionScope.ClassLevel)]`, and did not reproduce in isolation or in two subsequent clean full-suite runs. Making the accessor fail fast converts an intermittent, unattributed crash into a self-diagnosing exception raised at the point of misuse. The fix mirrors the `InvalidOperationException` contract already established for the same hazard in `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`. + +## What Changed + +Six source files, verified against the merge base with `git diff --name-status 87cb4df3..HEAD`. + +**Core logic (1 file)** + +- `UtilitiesCS/Threading/UiThread.cs` — the `Dispatcher` getter gains a null guard that throws `InvalidOperationException` naming the required `UiThread.Init()` call; `private static Dispatcher _dispatcher = null!;` becomes `private static Dispatcher? _dispatcher;`. The property's public type remains non-nullable `Dispatcher`, so callers keep receiving a guaranteed non-null value. + +**Tests (5 files)** + +- `UtilitiesCS.Test/Threading/UiThread_Tests.cs` — two regression tests plus a `DispatcherField()` reflection helper (+75 lines). +- `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs`, `ProgressTrackerAsync_Tests.cs`, `ProgressTracker_Tests.cs` — `[DoNotParallelize]` added; attribute-only, one line each. +- `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` — the `[TestInitialize]`/`[TestCleanup]` reflective snapshot moves from `GetProperty("Dispatcher", Public|Static)` to `GetField("_dispatcher", NonPublic|Static)`. No assertion, test method, or mock setup is added, removed, or altered; the class keeps all 8 `[TestMethod]` members. + +**Docs and evidence** + +The feature folder `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/` carries the issue, spec, research, atomic plan, three audit artifacts, and 30-plus evidence artifacts recording every gate. + +## Architecture / How It Fits Together + +`UiThread` holds process-global static UI-thread state. `UiThread.Init()` runs `Initialize()`, which captures the WPF `Dispatcher` into `_dispatcher`. Consumers read the static `UiThread.Dispatcher` property; `ProgressTrackerAsync.InitializeAsync()` is the consumer that exposed the defect. + +The change is confined to the accessor's contract. Control flow is unchanged on the initialised path: a captured dispatcher is returned exactly as before. Only the uninitialised path changes, from a silent `null` return to an immediate throw at the read site. + +Because the getter can now throw, any reflective read through the **property** surfaces the exception via `PropertyInfo.GetValue`. A repository-wide census (plan task `P0-T14`) enumerated every such route across all `.cs` files: the qualified expression `UiThread.Dispatcher`, the reflective property name `"Dispatcher"`, and the reflective field name `"_dispatcher"`. Exactly one reflective property consumer existed, and it is the sixth file changed here. No production file reads the dispatcher reflectively. + +## Verification + +**Completed** (recorded under the feature folder's `evidence/` tree) + +- Format: `dotnet tool run csharpier format .` scoped to the six owned paths, then `dotnet tool run csharpier check .` — `Checked 1576 files`, exit 0. +- Analyzers: `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` — exit 0, `0 Warning(s)`, `0 Error(s)`. +- Nullable: `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true` — exit 0, `0 Error(s)`. +- `UtilitiesCS.Test`: 4787 of 4787 passing, 0 failed, 0 skipped, against a 4785 baseline (+2 for the new regression tests). +- `QuickFiler.Test`: 1312 of 1312 passing, 0 failed, 0 skipped. All eight `EmailMoveMonitorTests` methods are named as passing; a recorded first pass had all eight failing before the sixth-file retarget, and that fail-before artifact is preserved. +- Changed-line coverage: 100% — 8 of 8 coverable added lines, each with 1 or more hits. +- Repository line-rate moved from 0.7073317 to 0.7073604, with a `lines-valid` delta of +42. +- Feature review: policy audit COMPLIANT with documented exceptions, code review APPROVE, feature audit ACCEPT, 7 of 7 acceptance criteria PASS, **0 blocking findings**. + +**Recommended** + +- Re-run the full four-step C# toolchain on the merge result. +- Confirm CI green on the branch head before merge. + +## Backward Compatibility / Migration Notes + +This is a behavioural change to a public API surface. `UiThread.Dispatcher` previously returned `null` when uninitialised and now throws `InvalidOperationException`. + +The census described above establishes that no production consumer depends on the silent-null outcome; every production read either follows initialisation or is a documentation cross-reference. The one test consumer that did depend on it is updated in this change. No public type signature changes: the property's declared type remains non-nullable `Dispatcher`. + +Callers that previously relied on a null return to detect uninitialised state must now call `UiThread.Init()` first, which is the intended contract and is named in the exception message. + +## Risks and Mitigations + +- **A consumer outside the census depends on the silent null.** The census covered the qualified expression, the reflective property name, and the reflective field name across every `.cs` file, and the review additionally checked the `using static UtilitiesCS.UiThread` route, which has zero hits. Rollback is a one-file revert with no data or migration considerations. +- **The coverage figures sit below the repository floor.** Both the baseline and the post-change figures are below it, and the shortfall is pre-existing rather than introduced here. These are raw unstripped `dotnet-coverage` figures for the whole `UtilitiesCS.Test` host process, which is a different denominator from the first-party testable one the policy governs; they are not comparable to the policy percentage. This change moves the figure up and achieves 100% changed-line coverage. +- **`[DoNotParallelize]` reduces test parallelism.** It applies to four classes that write one process-global static. The measured cost is immaterial against a 4787-test assembly, and the alternative is retaining a known order-dependent flake. + +## Review Guide + +1. `UtilitiesCS/Threading/UiThread.cs` — the entire behavioural change is here; it is small and self-contained. +2. `UtilitiesCS.Test/Threading/UiThread_Tests.cs` — confirm the regression tests are deterministic. +3. `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` — the reflection retarget; confirm no assertion changed. +4. The three `[DoNotParallelize]` additions are one line each and need little scrutiny. +5. `spec.md` and `plan.2026-09-02T09-02.md` are large but are planning records, not shipped behaviour. + +## Follow-ups + +These are non-blocking findings from the feature review. They are deferred rather than promoted on this branch: the plan's footprint acceptance criterion asserts the branch diff lists only the six owned source paths plus the feature folder, and adding a potential-entry document would falsify evidence already committed. They should be filed as a consolidated issue after this PR is open. + +- `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` is 514 lines, over the 500-line limit. This is pre-existing at the merge base and the branch delta for that file is zero lines; `[TestClass, DoNotParallelize]` was used specifically to avoid adding one. A partial-class split is the natural remedy. +- `ProgressTrackerAsync_Tests.cs` still mutates the reflective static directly; the spec records syncing it to the shared helper idiom as a follow-up. +- `UiThread_Tests.cs` omits a `field.Should().NotBeNull()` guard that its sibling test carries. +- `EmailMoveMonitorTests.cs` uses `DispatcherField?.GetValue(null)`; if the field were ever renamed, both sides would be null and the cleanup assertion would pass vacuously. This null-conditional pattern is retained from the pre-change code. +- `UiThread.cs` retains a `_uiSyncContext!` suppression, an untouched instance of the same pattern this change removes for `_dispatcher`. + +## GitHub Auto-close + +- None (GitHub validation unavailable) + +This pull request addresses issue #584. The automatic auto-close bullet is withheld because the PR-context bundle reports `GitHub CLI unavailable` and lists no verified closing issue, and the skill's reference rules forbid emitting a closing directive from unverified state. The bundle's author-asserted list additionally contained #449, #493 and #508, which appear in this branch's documents only as historical references — #449 as the run during which the defect was first observed — and must not be closed by this pull request. + +🤖 Generated with [Claude Code](https://claude.com/claude-code) + +https://claude.ai/code/session_01TzGiZSnVySFZcoC1BHN5Vv + +--- + +## Post-merge code review (three-phase, 2026-09-05) + +Review target: merge commit `1c3b210c`, diff `HEAD~1..HEAD` restricted to the six `.cs` files above, plus the 45 documentation and evidence files under the feature folder. + +Method.

The leaked, never-pumped dispatcher stays affinitized to a reused thread; a later test on that thread that resolves `Dispatcher.FromThread(Thread.CurrentThread)` (production default in `WpfDispatcherYield.cs:44`; test helper in `FilterOlFoldersControllerRefreshDisposalTests.cs:257-264` awaited without timeout) would hang. Latent today because the class is `[DoNotParallelize]` and recorded runs were per-assembly with `/InIsolation`. Fix: obtain the sentinel on a dedicated STA thread (pattern at `ProgressTrackerAsync_Tests.cs:130` or the `StaDispatcherHost` in `WpfUiDispatcherTests.cs:161-207`) and shut it down in `finally`. Keep the test rather than deleting it, so the populated branch stays covered in the regression file. + +**C02 — PLAUSIBLE.** `UtilitiesCS/Threading/UiThread.cs:138-146`. The getter reads the non-volatile static `_dispatcher` twice: once for the null check and once for the return. A null write landing between the two loads returns null despite the guard. Null-writers remain in the repository: `IdleAsyncQueue_Tests.ForceDispatcherNull`, `finally` restores of a null prior in the tracker tests, and QuickFiler.Test's ungated `EnsureScope.Dispose` (`CompareExchange` to null) under class-level parallelization. Within UtilitiesCS.Test all writers are now serialized, so the window is latent, and the failure mode is identical to pre-PR behavior. Fix: `Dispatcher? dispatcher = _dispatcher; if (dispatcher is null) throw ...; return dispatcher;` (or `Volatile.Read`), matching `OutlookFolderTreeService.cs:336` and `WebView2BreadcrumbHost.cs:159`. + +**C18 — CONFIRMED.** `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs:39-65`. `DispatcherField?.GetValue(null)` with a null-conditional on a `static readonly FieldInfo` means a rename of `_dispatcher` makes both snapshots null, and FluentAssertions 8.10 `BeSameAs` on a null subject with null expected passes, so the order-independence guard the class exists to enforce degrades to a no-op. The PR increased exposure by retargeting from a public property (rename is a solution-wide compile break) to a private field name with no compile-time coupling. The same assembly's `QfcItemController.UiThreadDispatcherFixture.cs:38-48` exposes `internal static Dispatcher Current`, a lock-guarded read of the same field whose `ResolveDispatcherField` asserts the field exists. Fix: replace the local `FieldInfo` and both `?.` reads with `UiThreadDispatcherFixture.Current`, and remove the two "avoid WindowsBase" comment fragments at lines 29 and 53 (see C25). + +**C19 — CONFIRMED.** `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs:236-240, 266-267, 272`. The P27-T2 docstring, the Act comment, and the `NotThrow` reason string still say a `NullReferenceException` from `InvokeAsync` on a null Dispatcher is caught "after the await". After this PR the exception is `InvalidOperationException`, thrown synchronously by the getter at `IdleAsyncQueue.cs:72` inside the `try` and before the first await, and swallowed only because the catch at line 83 is `catch (Exception)`. The test still passes; the documented mechanism is wrong. The PR edited this file (`[DoNotParallelize]`) without updating the text. Fix: rewrite the three passages to describe the synchronous `InvalidOperationException` path. + +**C20 — CONFIRMED.** `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs:57-66`. The comment "UiThread.Dispatcher ... is null outside a live host, so that null state is surfaced as InvalidOperationException" is now false: the production fallback provider `() => UtilitiesCS.UiThread.Dispatcher` (line 46) throws itself. The local `dispatcher is null` guard (lines 62-66) is unreachable on the production path and is retained only because the providers are typed `Func` under `#nullable enable`. The same precondition now emits two different messages depending on path; production always emits UiThread's message, never "...before yielding folder tree work." The plan (line 1294) acknowledged the divergence and accepted it. Fix: rewrite the comment to state that the fallback provider throws and that the guard covers injected providers; route both throws through one shared message constant; optionally add `.WithMessage("*UiThread.Init()*")` to `YieldAsync_WithoutDispatcher_RemainsStrict`. + +**C16 — CONFIRMED, pre-existing.** `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` is 514 lines at both `HEAD~1` and `HEAD`. `.claude/rules/general-code-change.md:49` and `CLAUDE.md:106` set a 500-line limit with no pre-existing or baseline exemption; a grep of `.claude/rules` and `.claude/skills` finds no "baseline + 1" file-size clause. That clause exists only in `plan.2026-09-02T09-02.md:941`. A plan-local acceptance clause cannot waive a CLAUDE.md rule under the Policy Compliance Order. The PR's own policy audit (line 109) discloses this as PARTIAL, so it is disclosed debt rather than a regression. Fix: split the file in a follow-up, and do not describe the `p2-t3` "baseline + 1" pass as rule compliance in review artifacts. + +**S3-2 — CONFIRMED.** `policy-audit.2026-09-04T04-05.md:123, 229, 421` and `feature-audit.2026-09-04T04-05.md:149` report that `dotnet tool run csharpier format .` was executed. `evidence/qa-gates/p4-t1-format.md:8` records a six-path scoped invocation, prescribed by plan P4-T1 (lines 1068-1084) to avoid repo-wide drift rewrites. The executor followed the plan; the misstatement is in the audits' transcription, and the deviation from the CLAUDE.md approved-command list is absent from the audit's section 8 "Gaps and Exceptions". Substantively equivalent: `p4-t2` ran whole-tree `check .` with exit 0 and an empty reported set. Fix: correct the command cells, amend row 3.1, and add a section 8 entry citing the plan rationale and the `check .` mitigation. Documentation only. + +### Nits (25) + +Code and tests: + +- **C03 — PLAUSIBLE, pre-existing.** `UiThread.cs:36`. `Init()` sets the one-shot `ThreadSafeSingleShotGuard` before `Initialize()` runs and has no catch or reset. If `Initialize()` throws after the guard flips, `_dispatcher` stays null permanently and the new message's remedy ("Call UiThread.Init()") is a no-op. In production an `Initialize()` failure aborts `ThisAddIn_Startup` before any consumer runs. Consider setting the latch after line 61 succeeds, and wording the message to not promise a retry re-runs initialization. +- **C05 — CONFIRMED, pre-existing split.** `UiThread.cs:137`. `UiSyncContext` and `AutoScaleFactor` lazily call `Init()` on null; `Dispatcher` throws. Read order now decides whether a caller self-heals or faults. The divergence predates the PR (Dispatcher was already the only non-lazy accessor) and is logged as CR-7 in the PR's code review, but no in-code comment explains why lazy `Init()` from an arbitrary reader is deliberately avoided here (`Initialize()` shows a hidden WinForms window and must run on the UI thread). Add a two-line comment above the throw. +- **C06 — CONFIRMED.** `UiThread.cs:142` and `UiThread_Tests.cs:152`. The message and the regression test both name the private method `UiThread.Initialize()`. The plan mandated the exact string. The sibling message at `WpfDispatcherYield.cs:65` names only the public `Init()`. Follow-up: shorten to "Call UiThread.Init() before reading UiThread.Dispatcher." and assert `*UiThread.Init()*`. +- **C08 — CONFIRMED.** `UiThread.cs:135`. The public static property gains a throwing precondition and carries no XML doc (`CLAUDE.md` C#6.2 and C#3.3). No member of `UiThread.cs` is documented today, and the policy says "should", so this is a nit. Add ``, `` noting the deliberate non-lazy contract, and ``. +- **C09 — CONFIRMED, pre-existing gap.** `UiThread.cs:142`. The message omits that `Init()` must run on the UI (STA) thread during startup. Neither `Init()` nor `Initialize()` checks apartment state; `SyncContextForm.CaptureUiVariables` captures `Dispatcher.CurrentDispatcher` on whatever thread calls it, so a worker-thread `Init()` succeeds silently and installs a non-pumping dispatcher into set-once globals (`QfcHomeControllerRunAsyncTests.cs:329` already calls `UiThread.Init(false)` from a test thread). Append the thread requirement to the message; open a follow-up for `Init()` to reject non-STA callers. +- **C11 — CONFIRMED.** `UiThread_Tests.cs:135-167`. Test 1 asserts `field.Should().NotBeNull()`; test 2 calls `field.GetValue(null)` unguarded, so a renamed field fails test 2 with a bare NRE in Arrange. Test 1 uses a block-bodied lambda where 396 of 407 throw-assertion lambdas in UtilitiesCS.Test are expression-bodied. Move the null guard into `DispatcherField()`; use `Action act = () => _ = UiThread.Dispatcher;`. +- **C12 — CONFIRMED.** `UiThread_Tests.cs:125`. `DispatcherField()` is the sixth reflection site for `UiThread._dispatcher` (also `IdleAsyncQueue_Tests.cs:144`, `ProgressTracker_Tests.cs:421`, `ProgressTrackerAsync_Tests.cs:138`, `EmailMoveMonitorTests.cs:40`, `UiThreadDispatcherFixture.cs:135`), each handling a missing field differently. `UtilitiesCS/Properties/AssemblyInfo.cs:19` grants `InternalsVisibleTo("UtilitiesCS.Test")`, so an internal test seam on `UiThread` could replace reflection for the four UtilitiesCS.Test sites. Follow-up; a bugfix PR is the wrong vehicle. +- **C13 — CONFIRMED.** `UiThread_Tests.cs:139-176`. Both new tests hand-roll capture, `SetValue`, `try`/`finally` restore. `IdleAsyncQueue_Tests` has `ForceDispatcherNull`/`RestoreDispatcher` but they are private and cannot install a non-null value. Same remedy as C12: one `IDisposable` install scope under `UtilitiesCS.Test/TestHelpers/`. +- **C14 — PLAUSIBLE.** `UiThread_Tests.cs:167`. While test 2 holds a never-pumped MTA dispatcher in the static, background work left alive by parallel-phase tests can read it. Concretely, `IdleActionQueue_Tests` has no cleanup and leaves no-op entries queued with a live `ApplicationIdleTimer` heartbeat subscription; a heartbeat in the microsecond window would enqueue a `DispatcherOperation` that never runs. No test-visible effect. Optional hygiene: add a `TestCleanup` to `IdleActionQueue_Tests` that drains entries and unsubscribes. +- **C15 — CONFIRMED.** `ProgressTracker_Tests.cs:14`. `[TestClass, DoNotParallelize]` is the only comma-combined attribute list among 41 `DoNotParallelize` usages in the repository; chosen to avoid growing a 514-line file. Split when the file is next touched, paired with the C16 split. +- **C17 — CONFIRMED.** `ProgressTracker_Tests.cs:14`, `ProgressTrackerAsync_Tests.cs:14`, `IdleAsyncQueue_Tests.cs:29`. Exactly one method per class touches `UiThread._dispatcher` (readers included), so class-level `[DoNotParallelize]` moves 32 non-touching tests into the serial bucket where method-level placement on the three writer methods would give the same guarantee. Defensible per plan rationale (grep-verifiable per-file invariant) and repo precedent (all 18 pre-existing usages are class-level); runtime cost is negligible. +- **C21 — CONFIRMED, pre-existing.** `WpfDispatcherYieldTests.cs:118`. No test constructs `new WpfDispatcherYield()` and reaches the production fallback provider; the concurrency test marshals onto an STA host first. The PR's research (`defect-scoping.md:147-162`) scoped this out. Follow-up: one `[DoNotParallelize]` test that nulls `_dispatcher`, calls `YieldAsync` from a thread with no dispatcher, and asserts `InvalidOperationException` with `*UiThread.Init*`. +- **C25 — CONFIRMED, pre-existing text.** `EmailMoveMonitorTests.cs:29, 53`. The comment justifies reflection by "avoiding a compile-time WindowsBase dependency". `QuickFiler.Test.csproj:460` references WindowsBase directly and ten sibling files import `System.Windows.Threading`. The PR appended an accurate paragraph (lines 32-37) beneath the false premise without correcting it. Delete the two clauses. +- **C26 — PLAUSIBLE.** `ProgressTrackerAsync_Tests.cs`. No test drives `InitializeAsync()` or `ProgressTracker.Initialize()` with a null dispatcher; AC3's consumer-level conversion is verified by code reading only (`p3-t4-progresstrackerasync-unmodified.md:58-71`). The accessor-level test was a documented scoping decision and demonstrably fails before and passes after the fix. Optional: add `InitializeAsync_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`. +- **S2-1 — CONFIRMED.** `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs:121-125`. The Arrange comment says an unset static "cannot complete an InvokeAsync"; the unset case now throws `InvalidOperationException` synchronously before any `InvokeAsync`. Comment-only. +- **S4-1 — CONFIRMED.** `.claude/agent-memory/task-researcher/project_qfc_collection_defects_468.md:41-42` and `project_filerqueue_consumer_unsound_633.md:3` state that `UiThread.Dispatcher` is "permanently null in tests" and "NREs". Stale after this PR; a future planning session loading these notes would reason from the wrong exception type. Update the notes (push-down surface owned by drm-copilot). +- **S4-2.** `evidence/qa-gates/p4-t5-utilitiescs-tests.md:7`, `p4-t6-quickfiler-tests.md`. The local toolchain step 4 ran only `UtilitiesCS.Test.dll` and `QuickFiler.Test.dll`; `TaskMaster.Test` (host of the ribbon and startup consumers) and the other five test assemblies were not run locally. CI's `mstest-coverage` job discovers every `*.Test.dll` and concluded success on the PR head, so no regression is indicated. Evidence-scope gap only. + +Documentation and evidence: + +- **S3-1 — CONFIRMED, downgraded to nit on verification.** `evidence/regression-testing/p1-t4-expect-fail.md:3,48` (Timestamp 08-31, "P1-T3 recorded a clean build immediately before this run") vs `p1-t3-build-before-fix.md:3` (08-33); `evidence/qa-gates/p3-t1-analyzer-build.md:3,30-31` (08-38, "the first build that compiles ... the production fix") vs `p3-t2-regression-green.md:3` (08-34) and `p3-t3-at-risk-tests.md:34` (TRX mtime 08:35:42). Every artifact with a hard marker has a Timestamp matching it to the minute, so the most likely reading is that P3-T1 ran after P3-T2..T5 and an unrecorded build produced the assembly they executed against. The fail-before/pass-after proof does not depend on the ordering prose: P1-T4's recorded output ("no exception was thrown", 1 failed) and P3-T2's output stand on their own, and Phase 4 pass 2 independently confirms the final state. Neither the skill nor the plan defines what instant `Timestamp:` denotes. Fix: soften the ordering sentences in the two artifacts and in `feature-audit.md:38` / `policy-audit.md:115`; define `Timestamp:` semantics in `evidence-and-timestamp-conventions`. +- **S3-3 — CONFIRMED.** `policy-audit.2026-09-04T04-05.md:68` states "All 34 evidence artifacts"; `git ls-tree` shows 38 at the audit commit and at HEAD. +- **S3-4.** `evidence/issue-updates/issue-584.2026-09-02T09-02.md`. Filename timestamp is the plan's timestamp; the artifact's own `Timestamp:` is `2026-09-03T22-24`. A second update to #584 would collide or mis-order. +- **S3-5.** `evidence/baseline/p0-t6-mcp-probe.md:12` (`EXIT_CODE: non-zero (...)`), `p1-t5-donotparallelize.md:11-13`, `p3-t5-no-timing-tokens.md:12-16`. `EXIT_CODE:` is not a single integer as the evidence schema requires. +- **S3-6.** `spec.md:7` Status remains "Draft" with all seven ACs checked and the PR merged; "In scope" (lines 62-70) lists three files, "Files/modules to change" (160-163) lists two, the Write Set (92-99) lists six. +- **S3-7.** `spec.md:50, 172` say "~40 other call sites"; `spec.md:73-74` says "~62 remaining direct reads across ~29 files"; a grep at the research base yields about 49 live reads in 26 production files. +- **S3-8.** `feature-audit.md:117, 119`, `code-review.md:22, 191`, `policy-audit.md:111`, `p2-t3-file-size.md:42` use evaluative wording ("honest and correct", "the right call", "Exemplary", "a model instance", "comfortably inside") that `.claude/rules/tonality.md` classifies as non-neutral. +- **S3-9.** `code-review.md:85` and `policy-audit.md:329-330` recommend promoting the ProgressTrackerAsync_Tests synchronization follow-up to a GitHub issue before merge. The PR merged and the feature folder holds no record that this happened. Not verified against GitHub from the review environment. + +### Refuted (6) + +- **C01.** `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs:72, 115`. The `dispatcher != null` checks are now dead code (true), but the claimed regression (loss of a degrade-to-direct-call fallback) does not hold: every production caller of `InvalidateEngineCommands`/`InvalidateEngineToggle` runs after `Application_Startup`, which requires `ThisAddIn_Startup` to have already run `UiThread.Init()` synchronously (`ThisAddIn.cs:35-42`), and the IdleAsyncQueue refresh path dereferenced the accessor without a guard before this PR. Any hypothetical exception is caught by `IdleAsyncQueue`'s catch, `HandleToggleClickAsync`'s click boundary, or `CompletePrime`'s continuation. Optional cleanup: remove the redundant null comparisons. +- **C04.** `UiThread.cs:36`. `CheckAndSetFirstCall` is non-blocking, so a concurrent second `Init()` caller returns before `Initialize()` completes (true), but the mechanism is pre-existing, untouched by this PR, and unreachable under the production startup ordering; the PR's getter neither widens nor narrows the window. +- **C07.** `UiThread.cs:137`. Collapsing the getter to `get => _dispatcher ?? throw ...` is legal but the premise is false: the adjacent `UiSyncContext` and `AutoScaleFactor` getters use the same block form, the `.editorconfig` preference is `silent`, and CSharpier would wrap the long message literal anyway. +- **C22.** `UtilitiesCS/Threading/ProgressTrackerPane.cs:13, 16`. The double read exists, but pre-PR a null static already failed at line 13 (NRE on `.Invoke`); the setter is private and set-once, so no production path can swap the static between reads; no test reaches the constructor. Exception type change only. +- **C23.** `ProgressTrackerAsync.cs:39`, `ProgressTracker.cs:39`. The inner re-read inside the `InvokeAsync` lambda exists, but issue #584's recorded NRE was at line 35, from the outer read at line 33; the inner read was never reached. Production never mutates `_dispatcher` after `Initialize()`, and every reflective writer is now serialized with the lambda drained by `PushFrame` before any restore. Optional tidy-up: pass the captured `UiDispatcher` into the lambda. +- **C24.** `UtilitiesCS/Threading/WpfUiDispatcher.cs:25`. Pre-PR the same members threw NRE at the same call sites before `Init()`; the PR changes only the exception type. The `StoreLockupResponder` path cannot execute before `Init()` because `ThreadMonitor` is constructed inside `Initialize()` after the dispatcher is assigned. `IUiDispatcher.cs` was not touched. + +### Verification notes + +- Verifiers checked the diff at `1c3b210c`, the full touched files, callers and callees, the feature folder's issue, spec, research, plan, and evidence artifacts, `.claude/rules`, `.claude/skills`, `CLAUDE.md`, `.editorconfig`, the test runsettings and `AssemblyInfo` parallelization attributes, and the CI workflow definitions. +- The review environment (Linux) could not run `msbuild`, `vstest.console.exe`, or `dotnet`; all conclusions are from static reading of source, configuration, and recorded evidence. Toolchain results were taken from the committed evidence artifacts and the CI check runs on the PR head, all of which concluded success. +- Nothing in this review was applied to the code.

The fix `Dispatcher? dispatcher = _dispatcher; if (dispatcher is null) throw ...; return dispatcher;` matches the in-repo precedent at `UtilitiesCS/OutlookObjects/Folder/OutlookFolderTreeService.cs:336` (`var dispatcher = _dispatcher;`) and `QuickFiler/Viewers/WebView2BreadcrumbHost.cs:159` (`BreadcrumbUiDispatcher? dispatcher = _dispatcher;`) — both verified present. | +| **C03** | **CONFIRMED** | `UiThread.cs:36` sets the latch *before* `Initialize()` at `:38`, with no `try`/`catch` and no reset. Because `_loaded` at `:46` is a mutable static, the minimal retry-enabling shape is a `catch { _loaded = new ThreadSafeSingleShotGuard(); throw; }` around `Initialize()`. That re-arm idiom already exists twice in-repo: `UtilitiesCS/Threading/IdleActionQueue.cs:65` and `UtilitiesCS/Threading/ApplicationIdleTimer.cs:454`. Moving `CheckAndSetFirstCall` to *after* `Initialize()` is the wrong remedy — it would let two concurrent callers both run `Initialize()`. | +| **C05** | **CONFIRMED** | `UiThread.cs:117-120` (`UiSyncContext` calls `Init()` when null) and `:160-163` (`AutoScaleFactor` calls `Init()` when null) both self-heal; `Dispatcher` at `:139` throws. No comment explains the asymmetry. The justification is verifiable: `Initialize()` at `:51-54` constructs and `Show()`s a WinForms `SyncContextForm`. | +| **C06** | **CONFIRMED** | The message at `:142` names the private `Initialize()`.

It already references the type by full name at + `WpfDispatcherYield.cs:46` (`UtilitiesCS.UiThread.Dispatcher`). +- `UtilitiesCS.Test` can read it through `InternalsVisibleTo` (§ A6), so a test may assert against + the constant rather than a hard-coded literal. +- `QuickFiler.Test` **cannot** — `UtilitiesCS/Properties/AssemblyInfo.cs` grants IVT only to + `DynamicProxyGenAssembly2` (`:18`), `UtilitiesCS.Test` (`:19`) and `ToDoModel.Test` (`:20`). No + QuickFiler.Test assertion on this text exists today (§ B15), so this is not a blocker. + +**Alternative considered and rejected:** a new `UtilitiesCS/Threading/UiThreadMessages.cs` holder +class. Rejected because it adds a file and a csproj `` entry for one string, and +`UiThread.cs` at 172 lines has ample headroom under the 500-line limit even after the C08 XML docs +and the C05 comment are added. + +Two message texts must be reconciled by the constant. C06 shortens the `UiThread` text to name only +`Init()`; C09 appends the UI/STA thread requirement; C20 routes the `WpfDispatcherYield` throw +through the same constant. The `WpfDispatcherYield` message today carries a domain-specific tail +("before yielding folder tree work") that a single shared constant necessarily drops. That loss is +intentional per C20 ("production always emits UiThread's message"), but the planner should state it +explicitly in an acceptance criterion so a reviewer does not read it as a regression. + +### A6. `InternalsVisibleTo("UtilitiesCS.Test")` — C12/C13 enabler + +**CONFIRMED:** `UtilitiesCS/Properties/AssemblyInfo.cs:19`: + +```csharp +[assembly: InternalsVisibleTo("UtilitiesCS.Test")] +``` + +Two duplicate grants of the same name also exist elsewhere in the assembly — +`UtilitiesCS/HelperClasses/Tokenizer.cs:11` and +`UtilitiesCS/OutlookObjects/Item/OlItemSummary.cs:10`.

The message-text half of C09 is delivered in issue #782; this entry is the behavior +change that #782 explicitly placed out of scope. + +## Problem + +- `UtilitiesCS/Threading/UiThread.cs:19-40` — `Init(...)` validates none of its callers' context. + Its only gate is the single-shot latch at `:36`, `if (_loaded.CheckAndSetFirstCall)`. +- `UtilitiesCS/Threading/UiThread.cs:48-79` — `Initialize()` constructs and `Show()`s a WinForms + `SyncContextForm` and then calls `CaptureUiVariables()`. No apartment check. +- `QuickFiler/Viewers/SyncContextForm.cs:34-40` — `CaptureUiVariables()` reads + `SynchronizationContext.Current`, `this.AutoScaleFactor`, `Dispatcher.CurrentDispatcher`, and + `Thread.CurrentThread.ManagedThreadId` from the calling thread unconditionally. +- Because the latch at `UiThread.cs:36` is single-shot, the **first** caller wins permanently. A + worker-thread `Init()` that happens to run first poisons the globals for the process lifetime, and + the exception message added by #782 ("Call UiThread.Init()...") offers no remedy, because `Init()` + has already run. +- The hazard is presently reachable only from tests: `QuickFiler.Test/Controllers/ + QfcHomeControllerRunAsyncTests.cs:329` calls `UiThread.Init(false)` from a plain `[TestMethod]` on + an MTA pooled worker. In production, `TaskMaster/ThisAddIn.cs:35-40` is the only direct caller and + runs on the Outlook STA. +- Two additional latent entry points exist: the `UiSyncContext` getter (`UiThread.cs:117-120`) and + the `AutoScaleFactor` getter (`UiThread.cs:160-163`) both call `Init()` when their backing field is + null, so any reader of either property on a non-STA thread is an implicit `Init()` caller. + +## Proposed Behavior + +- `UiThread.Init(...)` throws `InvalidOperationException` when + `Thread.CurrentThread.GetApartmentState() != ApartmentState.STA`, with a message naming the + requirement and the caller's observed apartment state. +- The check runs **before** the single-shot latch at `UiThread.cs:36` is consumed, so a rejected call + does not burn the one-shot and a subsequent correct call still initializes. This composes with the + C03 change delivered in #782 (re-arm the latch when `Initialize()` throws). +- The two lazy accessors keep their current self-healing behavior on the STA and surface the same + named exception off it, instead of silently capturing a worker thread's context. +- `QuickFiler.Test/Controllers/QfcHomeControllerRunAsyncTests.Worker_RunWorkerCompleted_HandlesCompletionCorrectly` + is migrated to an STA context (`[STATestMethod]`, or a dedicated STA thread with `Join()`), which is + the only in-repo caller the change breaks. + +## Acceptance Criteria + +- [ ] AC1: `UiThread.Init()` called from an MTA thread throws `InvalidOperationException` whose + message names the STA requirement and the observed apartment state. Covered by a deterministic + test that runs the Act on a dedicated MTA thread and joins it. +- [ ] AC2: `UiThread.Init()` called from an STA thread behaves exactly as before. Covered by a test + that asserts the single-shot latch, the captured dispatcher, and the captured + `UiThreadId` are unchanged. +- [ ] AC3: A rejected non-STA call does not consume the single-shot latch: a subsequent STA call in + the same process still runs `Initialize()`. +- [ ] AC4: `QfcHomeControllerRunAsyncTests.Worker_RunWorkerCompleted_HandlesCompletionCorrectly` + passes on an STA context, and a repository-wide grep confirms no remaining `UiThread.Init` + call site executes off the STA. +- [ ] AC5: The `UiSyncContext` and `AutoScaleFactor` lazy-`Init()` branches are covered for both the + STA (self-heals) and non-STA (throws) cases. +- [ ] AC6: The full C# toolchain (csharpier, analyzers, nullable, vstest with coverage) passes and + changed-line coverage does not decrease. +``` + +--- + +## E.

Neither figure is wrong; + the delegation prompt's phrasing localizes both to one file.

C# `async` methods capture all body exceptions into the returned `Task`; the + guarded read at `:33` therefore faults the task rather than throwing at the call site. +- **Impact:** a C26 test written as a synchronous `Should().Throw()` would + **fail**. It must be `await act.Should().ThrowAsync()` with + `Func act = () => tracker.InitializeAsync();`. +- **What the review body actually said** (`pr-778-review-source.md:157`, C26): only that no test + drives `InitializeAsync()` or `ProgressTracker.Initialize()` with a null dispatcher — it makes no + synchrony claim. The synchrony claim was introduced in `issue.md`'s Test Conditions. +- **Note:** `ProgressTracker.Initialize()` (`ProgressTracker.cs:31`, non-async) **does** throw + synchronously.

The S3-9 follow-up is satisfied by C12/C13, not C26 + +- **`issue.md:91-92` asserts:** the ProgressTrackerAsync_Tests synchronization follow-up, "if not + [promoted], is satisfied by C26 in this delivery". +- **Measured:** the follow-up as written in `policy-audit.2026-09-04T04-05.md:325-330` (finding F5) + and `spec.md:77-80` asks for "**adding synchronization** around + `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`'s existing reflection-based, + unsynchronized mutation of the shared static `UiThread._dispatcher`". C26 adds a *new test* + (`InitializeAsync_WhenDispatcherNotCaptured_...`) and changes no existing mutation. The item that + actually discharges F5 is **C12/C13** — the single shared install scope that all four + UtilitiesCS.Test reflection sites, including `ProgressTrackerAsync_Tests.cs:138-141`, migrate to. +- **Impact:** if the artifacts record "satisfied by C26", a future reader auditing F5 will look at + the wrong deliverable.

The file count differs by one. The most likely source of the extra + file is one of the five whose only `UiThread.Dispatcher` occurrence is non-live + (`EngineToggleStateCoordinator.cs`, `UiThread.cs`, `Theme.cs`, `IUiDispatcher.cs`, + `QfcHomeController.Iteration.cs`), but that is inference, not evidence — **UNVERIFIED**, because + the review's own member set is not recorded in the PR body. +- **Recommendation:** `spec.md` should carry **25**, with the derivation cited, and the delivery's + review artifact should note the 25-vs-26 divergence rather than silently adopting either figure. + +### D-6. `IdleActionQueue_Tests` is not `[DoNotParallelize]`; C14's cleanup touches shared globals + +- **`issue.md:69-70` asserts:** "C14: add a `TestCleanup` to `IdleActionQueue_Tests` that drains + entries and unsubscribes the heartbeat." No parallelization change is mentioned. +- **Measured:** the class carries `[TestClass]` only (`IdleActionQueue_Tests.cs:24-25`), and + `ApplicationIdleTimer.Unsubscribe` (`ApplicationIdleTimer.cs:471-478`) calls `Stop()` → + `instance.StopTimer()` (`:451-455`, `:159-182`) when the invocation list empties, mutating + process-global `Application.Idle` and `ApplicationIdleTimer.Guard` state shared with + `IdleAsyncQueue_Tests` and `ApplicationIdleTimer_Tests`. +- **Impact:** adding an unsubscribing cleanup to a parallel-bucket class can produce exactly the + class of cross-class interference the file header of `ApplicationIdleTimer_Tests.cs:10-15` + documents. The plan should pair C14 with `[DoNotParallelize]` on `IdleActionQueue_Tests`, or + restrict the cleanup to draining `_entries` / resetting `_subscribeGuard` / cancelling + `_unsubscribe` without unsubscribing the handler. + +### D-7. `artifacts/csharp/coverage.xml` format + +- **The delegation prompt asks:** "The delivery must produce `artifacts/csharp/coverage.xml` before + feature review; state exactly how to get there, including any conversion step." +- **Measured:** the pipeline produces **Cobertura**; the consuming hook parses **JaCoCo** only + (`.claude/hooks/validate-feature-review-coverage.ps1:216`, `:221-234`, `:186-206`). No committed + converter exists (Grep for `jacoco` under `scripts/`: no files).

This changes AC3's wording and the size of the documentation task. +2. **C06 test-method rename.** `UiThread_Tests.cs:134` + (`Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`) encodes the + old message target in its name. Renaming keeps the name honest but changes the fully-qualified + test id recorded in the #584 evidence artifacts + (`evidence/regression-testing/p1-t4-expect-fail.md:7` names it verbatim in a `/TestCaseFilter`). + Rename, or leave and note? +3. **The `WpfDispatcherYield` domain tail.** Routing both throws through one constant necessarily + drops "before yielding folder tree work" from the production message. Confirm that loss is + intended (C20's text implies yes) and state it in an acceptance criterion. +4. **C12/C13 vs C16 ordering.** Both touch `ProgressTracker_Tests.cs`. Migrating the reflection first + shrinks the file to ~508 lines (still over 500, so the split remains mandatory); splitting first + means the migration then edits the new file. Either order is workable; pick one so the plan's + task-level line-count assertions are stable. +5. **C14 parallelization (D-6).** Pair the new `TestCleanup` with `[DoNotParallelize]` on + `IdleActionQueue_Tests`, or narrow the cleanup so it does not unsubscribe? +6. **`spec.md` AC block for S3-6.** The review body states all seven #584 ACs are checked while + Status remains "Draft". I did not re-read the AC checkboxes line by line (UNVERIFIED), since the + remedy is a Status change either way. If the plan wants to assert the AC state in an artifact, it + must read `spec.md`'s AC block first. +7. **`plan.2026-09-02T09-02.md` line references.** S3-2's recommended section 8 entry cites the + plan's P4-T1 rationale at lines 1068-1084, and C16 cites a "baseline + 1" clause at line 941. + Both are taken from the review body and were **not** re-verified in this research (the plan file + was not read).

The three-phase post-merge review confirmed +the fix and found no functional regression. It also produced a set of residuals that are individually +small and that no single one of them justifies a separate delivery: two latent defects in the new +code, a set of test-hygiene and documentation nits, and a group of internal inconsistencies in the +#584 feature folder's audit and evidence artifacts. + +This delivery consolidates all of them into one Refactor pass so that none is lost when the #584 +feature folder is archived. Observable outcomes: + +- The `UiThread.Dispatcher` getter reads its backing field once, carries XML documentation, and + throws a single shared message that names only the public `Init()` entry point and states the + UI-thread requirement. +- `UiThread.Init()` can be retried after a failed `Initialize()`, so the remedy the message names is + actionable. +- All `UtilitiesCS.Test` manipulation of the `UiThread._dispatcher` static goes through one + disposable install scope with one reflection acquisition. +- No test file in the touched set exceeds the 500-line limit, and no test leaves an unshut dispatcher + on a pooled MTA worker thread. +- Comments and reason strings describe the current synchronous `InvalidOperationException` + mechanism rather than the pre-#778 `NullReferenceException` mechanism. +- The #584 feature folder's audits and evidence are internally consistent, schema-conformant, and + neutral in tone. + +## Behavioral Contract + +This section states what the changed production surfaces must do after the change. Behavior on the +initialized path is unchanged; only the uninitialized path and the message text change. + +### The shared message constant + +`UtilitiesCS/Threading/UiThread.cs` gains one member: + +```csharp +internal const string DispatcherNotInitializedMessage = + "The UI dispatcher has not been captured. Call UiThread.Init() on the UI (STA) thread during host startup before reading UiThread.Dispatcher."; +``` + +Placement: inside `UiThread`, adjacent to the `Dispatcher` property (currently lines 135-149), so the +constant and its thrower are read together. Accessibility `internal` is sufficient for every +consumer and is the accessibility CLAUDE.md § C#5.2 prefers for non-public API. `const` rather than +`static readonly` because the value is a compile-time literal with no initialization-order concern. + +The text reconciles three findings simultaneously: + +| Finding | Requirement | How the text satisfies it | +|---|---|---| +| C06 | name only the public `Init()`, not the private `Initialize()` | the literal contains `UiThread.Init()` and does not contain `UiThread.Initialize()` | +| C09 (message half) | state the STA / UI-thread requirement | the clause "on the UI (STA) thread during host startup" | +| C20 | one constant shared by both throw sites | the literal is domain-neutral and names no caller-specific operation | + +A rejected alternative: a new holder type `UiThreadMessages`. It adds a file and a csproj +`` entry for one string, and `UtilitiesCS/Threading/UiThread.cs` (172 lines +measured) has ample headroom under the 500-line limit even after the C08 XML documentation and the +C05 comment are added. + +### `UiThread.Dispatcher` + +Invariant: **the getter never returns null, and it never observes a value other than the one it +tested.** + +After the change the getter must: + +1. Read the static backing field exactly once into a local (C02). +2. Throw `InvalidOperationException(DispatcherNotInitializedMessage)` when that local is null. +3. Return that same local otherwise. +4. Not lazily call `Init()`. A two-line comment above the throw must state the reason: `Initialize()` + constructs and shows a hidden WinForms `SyncContextForm` and must run on the UI thread, so a lazy + `Init()` from an arbitrary reader is deliberately avoided here even though the sibling + `UiSyncContext` and `AutoScaleFactor` accessors do self-heal (C05). +5. Carry ``, `` documenting the deliberate non-lazy contract, and + `` XML documentation. The file currently carries zero + `///` comments (C08). +6. Keep its declared type non-nullable `Dispatcher` and keep its private setter. This is not a public + signature change. + +Accept-to-throw trace for one value. TaskMaster/ThisAddIn.cs calls `UiThread.Init(...)` on the +Outlook STA thread during startup; `Initialize()` assigns the captured dispatcher D to the backing +field. A later reader enters the getter, copies the field into the local — observing D — tests the +local, and returns D. No second read occurs, so a concurrent null write landing after the test +cannot cause a null return; the caller receives D or the exception, never null. On the uninitialized +path the local is null, the getter throws with the shared constant, and the exception propagates to +the caller unchanged. The getter absorbs nothing and introduces no new catch. + +### `UiThread.Init()` + +Signature, parameter names, and default values are unchanged. + +Invariant: **a failed initialization must not permanently consume the single-shot latch.** + +- `Init()` continues to gate `Initialize()` behind the single-shot latch (currently line 36, + `if (_loaded.CheckAndSetFirstCall)`). The latch must continue to be checked and set **before** + `Initialize()` runs, so two concurrent callers cannot both enter `Initialize()`. +- When `Initialize()` throws, `Init()` re-arms the latch by assigning a fresh + `ThreadSafeSingleShotGuard` to the backing field and rethrows the original exception unchanged, so + a subsequent `Init()` retries initialization (C03). The latch field is not `readonly` (currently + line 46), so reassignment is legal. The re-arm idiom already exists twice in the same assembly, in + UtilitiesCS/Threading/IdleActionQueue.cs and UtilitiesCS/Threading/ApplicationIdleTimer.cs. +- The broad catch is permitted by the General Code Change Policy only because it immediately + rethrows. It must carry a comment stating that it exists to re-arm the latch, not to absorb the + failure. +- No deterministic unit test covers this branch, because `Initialize()` shows a WinForms window and + cannot be forced to throw from a test without introducing a new production seam, which is out of + scope. The delivery's code-review artifact must record that reason. See AC2. +- `Init()` still performs no apartment-state check. Making it reject non-STA callers is out of scope + and is promoted separately under AC8. + +### `WpfDispatcherYield` + +`UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` (77 lines measured) contains exactly one +`throw`, at lines 62-67. C20's phrase "both throws" refers to that one plus the one in +`UtilitiesCS/Threading/UiThread.cs` — two files, one throw each, in the same `UtilitiesCS` assembly, +which is what makes a single `internal` constant viable. + +After the change: + +- Dispatcher-selection behavior is unchanged. The type still prefers the dispatcher affinitized to + the calling thread and falls back to the injected provider, whose production default is + `() => UtilitiesCS.UiThread.Dispatcher` (line 46). +- The local `dispatcher is null` guard throws `InvalidOperationException(UiThread.DispatcherNotInitializedMessage)`. +- **The domain-specific tail "before yielding folder tree work" is removed.** This loss is intended + (scope decision SD5) and is pinned by an acceptance criterion and by the C20 `WithMessage` + assertion, so a reviewer does not read it as a regression. Two facts bound the impact: the guard is + unreachable on the production path, because the production fallback provider throws from + `UiThread.Dispatcher` first with the same message; and the guard therefore covers only injected + providers, which are typed `Func` and exist only in tests. +- The comment at lines 53-59 is corrected. Its final clause ("UiThread.Dispatcher is set-once state + ... and is null outside a live host") is false after PR #778. The replacement must state that the + production fallback provider throws directly and that the local guard covers injected providers. + +## Scope + +### Write Set — production files (5) + +| File | Change (one line) | Findings | +|---|---|---| +| `UtilitiesCS/Threading/UiThread.cs` | 172 lines measured.

Do +not add backticks here. + +- **The C09 behavioral follow-up.** Making `UiThread.Init()` reject non-STA callers is a production + behavior change that breaks the live worker-thread `UiThread.Init(false)` call in + QuickFiler.Test/Controllers/QfcHomeControllerRunAsyncTests.cs. Only the message half of C09 is + delivered here. The behavioral half is promoted as its own entry under AC8; the research record + section D carries a drafted body, a blast-radius enumeration, and a recommended + `bug` / `full-bug` classification for that entry. +- **Finding S4-1** — stale notes under .claude/agent-memory/task-researcher/ that describe + `UiThread.Dispatcher` as "permanently null in tests" and as producing NREs. Recorded as an upstream + follow-up for the drm-copilot repository. +- **The S3-1 request to define `Timestamp:` semantics** in the evidence-and-timestamp-conventions + skill. The skill under .claude/skills/ specifies only `Timestamp: ` and defines no + semantics for which instant it denotes. Recorded as the same upstream follow-up. +- Both of the two items above live under .claude/, which is overwritten by push-down from + drm-copilot. Any edit made in this repository is silently lost. This delivery must not modify + anything under .claude/. +- **Findings needing no action:** C04 (pre-existing non-blocking latch race, untouched by PR #778), + C07 (expression-bodied getter; premise refuted, `.editorconfig` preference is silent), C17 + (class-level `[DoNotParallelize]` is defensible per plan rationale and repository precedent), C22 + (`ProgressTrackerPane` double read; setter is private and set-once, no production path can swap + between reads), C24 (`WpfUiDispatcher`; exception-type change only), S4-2 (evidence-scope + observation; CI ran every test assembly). +- **The `IUiDispatcher` seam conversion** replacing the remaining direct reads of + `UiThread.Dispatcher` across production files. Out of scope here and tracked elsewhere; this + delivery only corrects the figure the #584 spec quotes for it. +- **Adding the `.claude` worktree-exclusion guard to** scripts/vscode/Invoke-MSTest.ps1, and the + wrong-filename docstring in the same script. Both are separate PowerShell production changes; if + wanted, promote them as their own entries rather than folding them in. +- **artifacts/csharp/coverage.xml** is deliberately not produced. See the Constraints section. + +## Constraints + +1. **No temporary files in tests.** The General Unit Test Policy prohibits creating or using + temporary files in tests, with no currently approved exceptions. This binds the C10 STA sentinel, + the C21 fresh-thread test, and the C14 cleanup. +2. **STA sentinel discipline.** Any test that obtains a real `Dispatcher` must do so on a dedicated + STA thread, must call `BeginInvokeShutdown` on that dispatcher, and must join the thread in a + `finally` block, so no dispatcher outlives the test. Two verified in-repo patterns exist: the + `StaDispatcherHost` nested class in `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` + (lines 172-199), which is the closest match to what C10 asks for, and the inline + `Thread` / `SetApartmentState` / `Join` form with exception capture in + `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs` (lines 132-199). Global STA is + intentionally disabled in this repository; STA is opt-in per UtilitiesCS.Test/test.runsettings. +3. **C21's thread must be fresh.** The C21 test must reach the production fallback provider, which + requires a thread whose `Dispatcher.FromThread` is null while the `UiThread` static is null. On a + pooled MSTest worker, `Dispatcher.FromThread` returns non-null if any earlier test on that same + thread ever touched `CurrentDispatcher` — the exact hazard C10 fixes. The test must therefore run + its Act on a dedicated fresh thread that never touches `CurrentDispatcher`, and join it. + `[DoNotParallelize]` alone does not remove that coupling. +4. **C14 pairs with serialization (scope decision SD7).** The C14 cleanup unsubscribes the heartbeat + handler. `ApplicationIdleTimer.Unsubscribe` calls `Stop()` when the invocation list empties, and + `Stop()` touches process-global `System.Windows.Forms.Application.Idle` and + `ApplicationIdleTimer.Guard` state shared with `IdleAsyncQueue_Tests` and + UtilitiesCS.Test/Threading/ApplicationIdleTimer_Tests.cs. `[DoNotParallelize]` must therefore be + added to `IdleActionQueue_Tests` in the same edit, matching the precedent that + ApplicationIdleTimer_Tests already sets. +5. **500-line limit.** Every touched test file must end under 500 lines. This is a hard CLAUDE.md + rule with no baseline exemption. +6. **csproj registration.** Every new file must be registered as exactly one `` + entry in `UtilitiesCS.Test/UtilitiesCS.Test.csproj`. Duplicate `` entries are a + known past defect in this project (CS2002, issue #394), so the plan must assert exactly one entry + per new file. Follow the file's conventions: four-space indent, one self-closing element per line, + Windows backslash separators, appended adjacent to the sibling entry rather than sorted. +7. **Evidence files are edited in place.** No #584 evidence file is renamed. No existing `Timestamp:` + value is altered. The S3-4 remedy is an inserted note, not a rename or a re-stamp. +8. **Message-change grep discipline.** The C06/C09 message change breaks exactly one assertion, + `UtilitiesCS.Test/Threading/UiThread_Tests.cs` line 152. Grep for `UiThread.Initialize()` across + all projects before and after; the other occurrences at UiThread_Tests.cs line 113, + IdleAsyncQueue_Tests.cs line 156, and WpfDispatcherYieldTests.cs line 122 are prose, not + assertions. The line 113 occurrence is refreshed because the file is already in the write set. The + IdleAsyncQueue_Tests.cs passage at lines 155-160 is not factually wrong and is deliberately left; + record that as a decision, not an omission. +9. **Bugfix workflow scope.** This is a Refactor. The bugfix workflow's failing-regression-test-first + requirement applies only to C10 and C02. Both are latent-window defects: C10's hazard is a leaked + dispatcher that only manifests when a later test on the same pooled thread resolves + `Dispatcher.FromThread`, and C02's is a torn double read of a non-volatile static. A deterministic + in-suite failing test is likely to be structurally impossible for both. If so, record a + fail-before-exception dossier under this feature's evidence/regression-testing/ sub-path + rather than asserting a fail-before run that did not happen. That route is the one the + evidence-and-timestamp-conventions skill prescribes. +10. **Test assemblies to run.** This delivery touches the UtilitiesCS, TaskMaster, UtilitiesCS.Test, + and QuickFiler.Test projects, so at minimum UtilitiesCS.Test.dll, + QuickFiler.Test.dll, and TaskMaster.Test.dll must be run. Naming all nine test assemblies avoids + finding S4-2 recurring. Four shell-icon test classes stall on the local workstation for + environmental reasons that reproduce against main; exclude them with a TestCaseFilter and rely + on CI, and expect the `TryAddValuesAsync` flake tracked as issue #780. +11. **Coverage evidence (scope decision SD1).** artifacts/csharp/coverage.xml is deliberately not + produced for this delivery. The repository coverage pipeline emits Cobertura while the + feature-review coverage hook parses JaCoCo, so the path requires a throwaway conversion; and the + hook applies a fixed repository-wide line floor that would force a FAIL verdict for a shortfall + that pre-exists on origin/main. Coverage evidence is instead a compact package-level JaCoCo + summary committed under this feature's evidence/qa-gates/ sub-path. AC9's operative requirement is that + changed-line coverage does not decrease. +12. **Coverage figures must be re-derived before they are quoted.** Orchestrator scope decision SD1 + reports first-party line and branch coverage figures for the branch base. Those figures are not + derived in research/research.2026-09-05T16-10.md and carry no Numeric Derivation Evidence, so + this spec does not assert them and no acceptance criterion depends on them. Any artifact that + quotes a coverage figure must re-measure it and record the derivation. + +## Corrections to issue.md Encoded Here + +These are places where the requirements source is superseded. Each is an orchestrator scope +decision, not a unilateral change. + +| # | issue.md text | Correction | +|---|---|---| +| SD3 | S3-5 covers "the three named evidence files" | S3-5 covers all fifteen deviating files enumerated above. | +| SD4 | (silent) | The C06 assertion changes but the test method name `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` is deliberately **not** renamed. Its fully-qualified name is quoted verbatim inside a TestCaseFilter expression in a committed #584 regression-testing evidence artifact; renaming would make that recorded command resolve to zero tests. The residual naming inaccuracy is recorded in this delivery's code-review artifact. | +| SD5 | (silent) | The shared constant drops the `WpfDispatcherYield` message's "before yielding folder tree work" tail. Intended; pinned by AC10. | +| SD7 | "add a `TestCleanup` to `IdleActionQueue_Tests`" | The cleanup is implemented in full **and** `[DoNotParallelize]` is added to the class. | +| SD8 | Test Conditions: "`InitializeAsync` with null dispatcher throws synchronously" | **Incorrect.** `ProgressTrackerAsync.InitializeAsync` is `public async Task`, so the guarded read faults the returned task rather than throwing at the call site. The C26 test must use `Func act = () => tracker.InitializeAsync();` with `await act.Should().ThrowAsync()`. A synchronous assertion would fail. A second test asserts the genuinely synchronous throw from `ProgressTracker.Initialize()`, which is not async; that also closes C26's second named gap. | +| SD9 | S3-9: the follow-up "is satisfied by C26 in this delivery" | **Incorrect.** #584 finding F5 asks for synchronization around the existing unsynchronized reflective mutation of `UiThread._dispatcher`. That is discharged by C12/C13, the single shared install scope that all four `UtilitiesCS.Test` sites migrate to, not by C26, which adds a new test and changes no existing mutation. The artifact note must cite C12/C13 and may cite C26 as adjacent coverage. It must also record that the follow-up was verifiably never promoted: no potential entry and no active feature folder covers it, and the two recommendations that asked for it remain open. | +| SD10 | S3-7: "reconcile the call-site counts to the grep-verified figure" | The #584 spec document carries **49 live reads across 25 production files**, with the derivation cited. The PR #778 review body states 49 reads in 26 files. The artifact records the 25-versus-26 divergence rather than silently adopting either figure; the review body does not publish its member set, so the source of the extra file cannot be established. | + +## Items Requiring Re-derivation at Planning Time (SD11) + +The research record did not verify the two items below. The plan must re-derive each before writing +any assertion that depends on it. Do not carry these forward as established facts. + +1. **The #584 spec document's acceptance-criteria block state (S3-6).** The PR review body states that all + seven of that spec's acceptance criteria are checked while its Status still reads "Draft". The + research did not read the AC checkboxes line by line, because the S3-6 remedy is a Status change + either way. If the plan asserts the AC state in an audit amendment, it must read the AC block + first. +2. **Two line references into the #584 plan file.** The S3-2 section 8 gap entry is expected to cite + that plan's P4-T1 rationale, and the C16 discussion cites its "baseline + 1" file-size clause. Both + line numbers come from the PR review body and were not re-verified; the plan file was not read. + Confirm both before quoting them. + +## Traceability + +Every in-scope finding identifier, the file it changes, and the acceptance criterion that covers it. + +| ID | File(s) changed | AC | +|---|---|---| +| C01 | `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` | AC4 | +| C02 | `UtilitiesCS/Threading/UiThread.cs` | AC1 | +| C03 | `UtilitiesCS/Threading/UiThread.cs` | AC2 | +| C05 | `UtilitiesCS/Threading/UiThread.cs` | AC2 | +| C06 | `UtilitiesCS/Threading/UiThread.cs`, `UtilitiesCS.Test/Threading/UiThread_Tests.cs` | AC2, AC10, AC11 | +| C08 | `UtilitiesCS/Threading/UiThread.cs` | AC2 | +| C09-message | `UtilitiesCS/Threading/UiThread.cs` | AC2, AC10 | +| C10 | `UtilitiesCS.Test/Threading/UiThread_Tests.cs` | AC1 | +| C11 | `UtilitiesCS.Test/Threading/UiThread_Tests.cs` | AC2 | +| C12 | `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs`, `UtilitiesCS.Test/UtilitiesCS.Test.csproj` | AC5 | +| C13 | `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`, `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` | AC5 | +| C14 | `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs` | AC2 | +| C15 | `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` | AC2, AC6 | +| C16 | `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, `UtilitiesCS.Test/UtilitiesCS.Test.csproj` | AC1, AC6 | +| C18 | `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` | AC1, AC5 | +| C19 | `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` | AC1 | +| C20 | `UtilitiesCS/Threading/UiThread.cs`, `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`, `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` | AC1, AC10 | +| C21 | `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` | AC2, AC7 | +| C23 | `UtilitiesCS/Threading/ProgressTracker.cs`, `UtilitiesCS/Threading/ProgressTrackerAsync.cs` | AC4 | +| C25 | `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` | AC2 | +| C26 | `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs` | AC2, AC7 | +| S2-1 | `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs` | AC2 | +| S3-1 | `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/evidence/regression-testing/p1-t4-expect-fail.md`, `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/evidence/qa-gates/p3-t1-analyzer-build.md`, `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/feature-audit.2026-09-04T04-05.md`, `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/policy-audit.2026-09-04T04-05.md` | AC3 (artifact softening);

The C03 clause is satisfied when + `UtilitiesCS/Threading/UiThread.cs` contains a catch around `Initialize()` that assigns a fresh + single-shot guard and rethrows the original exception unchanged, and the code-review artifact + records why no unit test covers that branch. **Evidence:** one diff hunk per identifier, mapped + by the traceability table; the code-review artifact for any omission. +- [ ] AC3: Each of the eight in-scope documentation and evidence nits is resolved in the #584 feature + folder, with these amendments: S3-5 is applied to all fifteen files in the S3-5 member set + above, not only the three named in issue.md (SD3); S3-9's note cites C12/C13 as the discharging + item and records that the follow-up was never promoted (SD9); S3-7 states 49 live reads across + 25 production files with the derivation cited and records the review body's 26-file figure as a + divergence (SD10); S3-1 covers only the four artifact softenings, the `Timestamp:`-semantics + request being out of scope under AC8. **Evidence:** a grep over the #584 evidence subtree in + which every `EXIT_CODE:` line matches a single signed integer and nothing else; a `git diff` + over the #584 folder listing exactly the files named in the Write Set sections above; a grep + over the four audit artifacts returning zero occurrences of the six evaluative spans S3-8 + names. +- [ ] AC4: The two optional refuted-item cleanups are applied. `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` + contains no `dispatcher != null` comparison and its two XML-doc mentions of `UiThread.Dispatcher` + are unchanged; `UtilitiesCS/Threading/ProgressTracker.cs` and + `UtilitiesCS/Threading/ProgressTrackerAsync.cs` each pass the captured `UiDispatcher` local into + the marshalling lambda and no longer re-read the static inside it. **Evidence:** the diff for + the three files, plus a grep confirming zero remaining `UiThread.Dispatcher` reads inside those + two lambdas. +- [ ] AC5: `UtilitiesCS.Test` contains exactly one acquisition of a `FieldInfo` for + `UiThread._dispatcher`, in `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs`, and the + four former sites listed in the migrating-sites table all use that scope. + `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` contains no `FieldInfo` for + `_dispatcher`. At least one migrated test in `UtilitiesCS.Test/Threading/UiThread_Tests.cs` + installs a non-null dispatcher over a null prior value and asserts, after the scope is + disposed, that the static is null again. **Evidence:** a repository-wide grep for + `GetField("_dispatcher"` returning exactly two hits — the new scope and the unchanged + QuickFiler.Test fixture — and the named restore test passing. +- [ ] AC6: `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` and + `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs` are each strictly under 500 + lines, both are registered as exactly one `` entry in + `UtilitiesCS.Test/UtilitiesCS.Test.csproj`, both declare the same `partial class` with the + `[TestClass]` and `[DoNotParallelize]` attributes on separate lines in exactly one part, and + every test method that existed in the pre-split file is still discovered and passing under its + original fully-qualified name. **Evidence:** a line-count artifact for both files; the csproj + diff; a before-and-after test-name list from the `UtilitiesCS.Test` run. +- [ ] AC7: Three new tests exist and each fails if its corresponding throw is removed and passes on + the current code — the C21 test that reaches the production fallback provider from a dedicated + fresh thread with no dispatcher, the C26 asynchronous test asserting + `ThrowAsync` from `ProgressTrackerAsync.InitializeAsync`, and the + C26 synchronous sibling asserting the direct throw from `ProgressTracker.Initialize()`. + **Evidence:** a fail-before / pass-after artifact under this feature's + evidence/regression-testing/ sub-path recording each test's result with the guard temporarily + removed and restored. +- [ ] AC8: The C09 behavioral follow-up (making `UiThread.Init()` reject non-STA callers) is promoted + as its own potential entry through the promotion lifecycle and carries a GitHub issue number; + and the S4-1 stale agent-memory notes together with the S3-1 request to define `Timestamp:` + semantics are both recorded as upstream follow-ups for the drm-copilot repository. Neither is + fixed in this repository. **Evidence:** the promoted entry file plus its issue URL, and the + upstream follow-up record in this delivery's artifacts; plus a `git diff --stat` showing zero + changed files under .claude/. +- [ ] AC9: The full C# toolchain passes in a single final pass — CSharpier format then check, + analyzer build, nullable build, and the test run with coverage over the named assemblies — and + changed-line coverage does not decrease.

The findings are heavily +coupled: the message-text change touches the same lines as the shared-constant change and the XML +documentation; the reflection consolidation and the file split touch the same file, so their ordering +has to be decided once rather than negotiated across two branches; and eight of the findings are +corrections to audit artifacts that only make sense as one internally consistent edit. Each item +individually is too small to justify a branch, a plan, a review cycle, and a toolchain pass, which is +exactly why items of this size are normally lost. Consolidating them makes the fixed cost payable +once and gives one reviewable diff whose scope is bounded by an explicit finding-to-file mapping. + +The consolidation is deliberately not unlimited. Two findings that require a production behavior +change or an edit to a push-down-owned tree are excluded and tracked separately, so the delivery +stays a Refactor with no new behavior beyond the exception message text. + +## Done When + +Observable, in this order: + +1. `git diff` against the merge base lists exactly the files named in the specification's Write Set + sections, and nothing under .claude/. +2. Every finding identifier in the specification's traceability table is either present in that diff + or recorded as an omission with a stated reason in the delivery's code-review artifact. +3. The full C# toolchain — CSharpier format then check, analyzer build, nullable build, and the test + run with coverage — passes in a single final pass, with one evidence artifact per step recording + its exact command and exit code. +4. No test file in the touched set exceeds 500 lines, and every test that existed before the split is + still discovered and passing under its original fully-qualified name. +5. Every `EXIT_CODE:` field in the #584 evidence tree is a single integer. +6.

From 4007d23ed6ee48fc98ff2c83d5135242ea83574d Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 18:30:15 -0400 Subject: [PATCH 03/28] docs(782): add the atomic implementation plan and correct AC5 evidence Adds the 9-phase, 101-task atomic plan for issue #782 after two preflight revision rounds, and amends the spec's AC5 evidence method. AC5 previously named the token GetField("_dispatcher", which matches no single line anywhere in the tree because CSharpier wraps all six acquisition sites. The criterion could not fail. It now names the wrap-tolerant token "_dispatcher" scoped to *.cs files, matching the plan tasks that verify it.

The dotnet local-tool manifest is at the repository root as `dotnet-tools.json`, not + `.config/dotnet-tools.json`. It pins CSharpier 1.2.6 only. `dotnet tool restore` has already been + run successfully; no task re-runs it. +3. `packages/` is restored. All five analyzer packages resolve and match every `` + path across all 16 first-party project files. No analyzer-version skew exists on this branch. +4. `msbuild` resolves to the Visual Studio 18 Community MSBuild. +5. `dotnet-coverage` 18.10.0 is installed globally and is invoked by its bare name. +6. `vstest.console.exe` is resolved through vswhere: + + ```powershell + $vswhere = "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" + $vstest = & $vswhere -latest -products * -find Common7\IDE\Extensions\TestPlatform\vstest.console.exe | + Select-Object -First 1 + ``` + +7. **Semicolon-bearing switches must be quoted.** PowerShell treats `;` as a statement separator, so + `/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None` and + `/flp:LogFile=coverage\782-p0-nullable.log;Verbosity=normal` are truncated at the first semicolon + when written bare. Every task that names one of these switches passes it as a single quoted + argument, for example `'/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'`, and the + artifact records the quoted form in its `Command:` field. A task that re-runs a command by + reference rather than by quoting it is bound by this item exactly as if it had named the switch. + [P4-T8] is the only such task: it re-runs the [P4-T7] invocation, so it passes + `'/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'` in single quotes and records the + quoted form in its artifact's `Command:` field. + +### The nine test assemblies + +Every test task in this plan passes these nine explicit assembly paths.

It is written in single quotes here and in every task +below, for the reason stated in item 7 above. + +The `/TestCaseFilter` expression is exactly: + +```text +TestCategory!=LiveOutlook&FullyQualifiedName!~HelperClasses.ShellUtilities_Tests&FullyQualifiedName!~HelperClasses.ShellUtilitiesStatic_Tests&FullyQualifiedName!~HelperClasses.SysImageListHelperTests&FullyQualifiedName!~EmailIntelligence.OSBrowser_Tests +``` + +Those four classes issue `SHGetFileInfo` with `SHGFI_ICON`, which stalls process-wide on this +workstation and hangs the test host.

The allowlist is the nine production assembly names: +`Tags`, `ToDoModel`, `TaskVisualization`, `UtilitiesCS`, `QuickFiler`, `TaskTree`, `TaskMaster`, +`SVGControl`, `VBFunctions`. + +`coverage/*` and `[Tt]est[Rr]esult*/` are both git-ignored, so the raw Cobertura document and the TRX +files never enter the commit. Only the derived summary artifacts under the feature folder's +`evidence/` subtree are committed. + +`artifacts/csharp/coverage.xml` is deliberately **not** produced (scope decision SD1). No task in +this plan writes that path. + +## Scope Decisions Encoded Here (do not re-open) + +| ID | Decision as encoded | +|---|---| +| SD1 | `artifacts/csharp/coverage.xml` is not produced. Coverage evidence is a package-level summary under `evidence/qa-gates/`. | +| SD3 | S3-5 is applied to all 15 deviating `EXIT_CODE:` files, not the 3 named in `issue.md`. | +| SD4 | C06 changes the assertion; the test method name `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` is not renamed. | +| SD5 | Both throw sites route through one `internal const string` on `UiThread`. The `WpfDispatcherYield` message loses its "before yielding folder tree work" tail; the loss is pinned by a `WithMessage` assertion. | +| SD6 | The C16 file split runs before the C12/C13 reflection migration. | +| SD7 | C14 implements the full cleanup and adds `[DoNotParallelize]` to `IdleActionQueue_Tests`. | +| SD8 | The C26 asynchronous test asserts `ThrowAsync`; a second test asserts the synchronous throw from `ProgressTracker.Initialize()`. | +| SD9 | The S3-9 note cites C12/C13 as the item discharging #584 finding F5, and records that F5 was never promoted. | +| SD10 | S3-7 adopts 49 live reads across 25 production files and records that the review body states 26. | +| SD11 | Both re-derivation items are re-derived in Phase 0 before any artifact quotes them. | +| SD13 | C10 and C02 receive a fail-before exception dossier. C21 and C26 receive real fail-before demonstrations. | +| SD14 | The `ForceDispatcherNull` docstring in `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` is rewritten to describe the post-#778 synchronous `InvalidOperationException` mechanism and to name `Init()`. This supersedes the `spec.md` Constraint 8 clause that leaves the passage at lines 155-160 untouched; the supersession is recorded in the code-review artifact. | +| SD15 | `issue.md` is not modified by this plan. | +| SD16 | `spec.md` AC5's evidence clause is amended at planning time. The clause originally demanded a repository-wide grep for the single-line token `"_dispatcher"` returning exactly two hits; an unrestricted repository-wide grep also matches `spec.md` itself, this plan, the research artifact, and several `#584` artifacts, so it could never return two. The clause now scopes the grep to all `*.cs` files in the repository, which is the scope P0-T13 and P3-T10 already use. | +| SD17 | The `/EnableCodeCoverage` switch named in CLAUDE.md § CUT3 step 4 and in `spec.md` Toolchain step 4 is not passed. `scripts/vscode/TaskMaster.cli.runsettings` carries no data collector and no coverage exclusions, so the built-in collector instruments Deedle and FSharp.Core, which is the failure mode `coverage.config` exists to prevent. Coverage is collected instead by `dotnet-coverage collect` with the derived configuration, in P0-T7 for the baseline and P7-T5 for the final pass, so both figures come from one method and remain comparable. | + +**Out of plan scope.** The promotion of the C09 behavioural follow-up, pull-request creation, and the +CI gate are orchestrator steps. This plan does not perform them. AC8 and AC-U1 therefore carry +explicitly gated two-branch check-off tasks in Phase 8 that set the box only when the orchestrator's +artefact is already present on disk, and otherwise leave the box unchecked with a recorded deferral. + +## The Shared Message Constant + +`UtilitiesCS/Threading/UiThread.cs` gains exactly one member, placed adjacent to the `Dispatcher` +property (currently lines 135-149).

If the printed count differs from 1580, record both the printed value and the expected 1580 in the artifact, record the observed value on its own line as `BASELINE_CHECKED_FILES: `, and continue; P7-T2 then derives its expected value from that recorded observation rather than from the tabled 1580. + +- [ ] [P0-T4] Capture the analyzer-build baseline. Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true`. Write `evidence/baseline/p0-t4-analyzer-build.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting the `Warning(s)` line, the `Error(s)` line, and the count of distinct project build-output lines. Acceptance: `EXIT_CODE: 0`, the recorded warning line is ` 0 Warning(s)`, the recorded error line is ` 0 Error(s)`, and the recorded project count is 16. If the recorded project count differs from 16, record both the observed value and the expected 16, record the observed value on its own line as `BASELINE_PROJECT_COUNT: `, and continue; P7-T3 then derives its expected value from that recorded observation rather than from the tabled 16. The `0 Warning(s)` and `0 Error(s)` conditions carry no such escape and remain hard. + +- [ ] [P0-T5] Capture the nullable-build baseline. Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true /v:n '/flp:LogFile=coverage\782-p0-nullable.log;Verbosity=normal'`. The `/flp:` switch is written in single quotes because PowerShell would otherwise truncate it at the first semicolon and no log file would be produced. Do not add `/p:Nullable=enable`; do not substitute `/t:Build`. Write `evidence/baseline/p0-t5-nullable-build.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting the `Warning(s)` line, the `Error(s)` line, the total line count of the log file, and the number of lines in the log containing the token `CoreCompile`. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`, and the recorded `CoreCompile` execution count is 51. Record the observed log line count beside the expected 11903; a difference in log length alone is not a failure. If the recorded `CoreCompile` count differs from 51, record both the observed value and the expected 51, record the observed value on its own line as `BASELINE_CORECOMPILE_COUNT: `, and continue; P7-T4 then derives its expected value from that recorded observation rather than from the tabled 51. The `0 Warning(s)` and `0 Error(s)` conditions carry no such escape and remain hard. + +- [ ] [P0-T6] Capture the test baseline over all nine assemblies. Resolve `$vstest` through vswhere, then run vstest with the nine explicit assembly paths, `/Settings:scripts\vscode\TaskMaster.cli.runsettings`, `/InIsolation`, `/Logger:trx`, `/ResultsDirectory:TestResults\782-p0-baseline`, `'/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'` written in single quotes so PowerShell does not truncate it at the first semicolon, and the mandatory `/TestCaseFilter` expression. `/EnableCodeCoverage` is deliberately not passed. `scripts/vscode/TaskMaster.cli.runsettings` carries no data collector and no coverage exclusions, so the built-in collector would instrument Deedle and FSharp.Core, which is the failure mode `coverage.config` exists to prevent; `scripts/vscode/Invoke-MSTestWithCoverage.ps1` lines 22-24 state that omission is deliberate. Coverage for the baseline is collected separately by P0-T7 through `dotnet-coverage` with the derived configuration. The tabled 6992/6992/0 figure was measured without `/EnableCodeCoverage`. Write `evidence/baseline/p0-t6-vstest.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting the `Total tests:`, `Passed:`, `Failed:`, and `Skipped:` values and stating explicitly that these are locally-filtered figures with the four shell-icon classes excluded, not CI figures. Acceptance: `EXIT_CODE: 0`, `Total tests: 6992`, `Passed: 6992`, `Failed: 0`. If `TryAddValuesAsync_UpdatesExistingValue` is the only failure, record it as the known issue #780 flake, re-run once, and record both runs. If the total differs from 6992 for any reason other than the `TryAddValuesAsync_UpdatesExistingValue` flake, record both the observed and the expected value, record the observed value on its own line as `BASELINE_TOTAL_TESTS: `, and continue; P4-T11 and P7-T5 then derive their expected minimum from that recorded observation plus three rather than from the tabled 6992. `Failed: 0` carries no such escape and remains hard. + +- [ ] [P0-T7] Capture the coverage baseline. Build the derived coverage configuration at `coverage\782-effective-coverage.config` from repo-root `coverage.config` by appending one `.*\.Test\.dll$` to the `Exclude` element, then run `dotnet-coverage collect --output coverage\782-p0-baseline.cobertura.xml --output-format cobertura --settings coverage\782-effective-coverage.config -- $vstest /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p0-coverage '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None' /TestCaseFilter:""`, with the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon. Do not pass `/EnableCodeCoverage` here; `dotnet-coverage` performs the instrumentation and the two collectors conflict. From the resulting Cobertura document, sum `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` over only the `` elements whose name matches one of the nine first-party allowlist assembly names, and separately record the document root totals. Write `evidence/baseline/p0-t7-coverage.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` carrying, as explicit numerals, the first-party `lines-covered`, `lines-valid`, line percentage, `branches-covered`, `branches-valid`, and branch percentage, plus the root all-modules line and branch percentages, plus a sentence stating that only the first-party figure is comparable to policy. Acceptance: the artifact records first-party line coverage of 112357/132967 = 84.50% and branch coverage of 26496/33480 = 79.14%, each within 0.05 percentage points of those values; the root all-modules figures are also recorded; and `lines-valid` for the first-party set is recorded so the Phase 7 comparison can test comparability. If the first-party figures deviate by more than 0.05 percentage points, record both the observed and the expected values and continue, because the Phase 7 gate compares against the observed baseline, not the tabled one. + +- [ ] [P0-T8] Record the baseline line counts of every file in the Write Set. For each of the eleven existing source and test files named in the Write Set section, run `(Get-Content -LiteralPath '').Count`. Write `evidence/baseline/p0-t8-line-counts.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` carrying one row per file with the counting command and the observed count. Acceptance: the artifact records `UtilitiesCS/Threading/UiThread.cs` 172, `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` 77, `UtilitiesCS.Test/Threading/UiThread_Tests.cs` 179, `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` 514, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs` 206, `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` 348, `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs` 241, `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` 201, `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` 320, and `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs` 393. Any deviation is recorded in the artifact and reported before Phase 1 begins. + +- [ ] [P0-T9] Re-derive the #584 specification's acceptance-criteria block state and Status line (SD11 item 1, required by AC12). Read `#584/spec.md` lines 1-15 and run a search over that file for lines matching `^- \[[ x]\] AC`. Write `evidence/baseline/p0-t9-584-spec-rederivation.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` quoting the current `- **Status:**` value verbatim, the current `- **Version:**` value verbatim, and every matched acceptance-criteria line with its line number. Acceptance: the artifact records that all seven acceptance criteria carry `[x]`, that Version is `0.5`, and that the Status value begins with the token `Draft`. Any subsequent task that asserts the #584 acceptance-criteria state must cite this artifact; if the observed state differs from all-seven-checked, the S3-6 task in Phase 5 amends only the Status line and records the divergence rather than editing checkboxes. + +- [ ] [P0-T10] Re-derive the two line references into the #584 plan file (SD11 item 2, required by AC12). Read `#584/plan.2026-09-02T09-02.md` lines 936-946 and lines 1064-1086. Write `evidence/baseline/p0-t10-584-plan-rederivation.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` quoting line 941 verbatim and quoting the P4-T1 command line and the six-path owned-file list from lines 1068-1084 verbatim. Acceptance: the artifact records that line 941 contains the token `PRE-EXISTING FILE-SIZE OVERAGE:` and the phrase about a post-change count no greater than the P0-T13 baseline plus one; and that the command recorded at lines 1068-1084 is a `dotnet tool run csharpier format` invocation whose operands are six explicit paths and which does not carry `.` as its operand. This artifact is the sole basis on which Phase 5 may quote those two locations. + +- [ ] [P0-T11] Census the serialization state of every test class that shares `ApplicationIdleTimer` process-global state, as SD7 requires. Read the class-declaration region of `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs`, `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs`, and `UtilitiesCS.Test/Threading/ApplicationIdleTimer_Tests.cs`. Write `evidence/baseline/p0-t11-idle-serialization-census.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` recording, for each of the three classes, whether it carries `[DoNotParallelize]` and at which line. Acceptance: the artifact records that `IdleAsyncQueue_Tests` carries `[DoNotParallelize]` at line 29, that `ApplicationIdleTimer_Tests` carries it at line 17, and that `IdleActionQueue_Tests` does **not** carry it (its `[TestClass]` is at line 24 and the class declaration at line 25). This finding is the stated justification for the SD7 attribute addition in P4-T1 and must be repeated in the code-review artifact. + +- [ ] [P0-T12] Census the deviating `EXIT_CODE:` fields in the #584 evidence subtree (S3-5 member set, SD3). Search `#584/evidence` for lines matching `^EXIT_CODE:` with file paths and line numbers. Write `evidence/baseline/p0-t12-exitcode-census.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` listing every matched file with its line number and the full text of the matched line, partitioned into a conforming set (the line matches `^EXIT_CODE: -?[0-9]+$` exactly) and a deviating set. Acceptance: the artifact records a total population of 37 files carrying an `EXIT_CODE:` field, 22 conforming and 15 deviating, and the 15 deviating paths are exactly the 15 enumerated in the Phase 5 S3-5 task list. Any divergence between the census and that list is reported before Phase 5 begins. + +- [ ] [P0-T13] Census every reflective acquisition of a `FieldInfo` for `UiThread._dispatcher`. Search all `*.cs` files repository-wide for the single-line token `"_dispatcher"` and separately for the single-line token `typeof(UiThread)`. The conjunction `GetField("_dispatcher"` is not used, because CSharpier wraps every acquisition so that `GetField(` and `"_dispatcher",` never share a line. Write `evidence/baseline/p0-t13-reflection-census.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` listing every site with its file and line number. Acceptance: the `"_dispatcher"` search returns exactly six lines, at `UtilitiesCS.Test/Threading/UiThread_Tests.cs` line 128, `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` line 422, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs` line 139, `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` line 145, `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` line 41, and `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` line 136; the `typeof(UiThread)` search returns exactly seven lines, the first six being the immediately preceding line of each of those same six acquisitions (127, 421, 138, 144, 40, and 135 respectively) and the seventh being `UtilitiesCS.Test/OutlookObjects/Folder/FolderPredictorTests.cs` line 469, which the artifact records as targeting `"_uiSyncContext"` and therefore outside the C12/C13 family. This is the before-figure for the AC5 gate in P3-T10. + +### Phase 1 — Production Source Changes and the Shared Message Constant + +- [ ] [P1-T1] Add the shared message constant to `UtilitiesCS/Threading/UiThread.cs`. Insert exactly one member, `internal const string DispatcherNotInitializedMessage`, whose value is the verbatim literal quoted in the section "The Shared Message Constant" above, placed immediately above the `Dispatcher` property declaration (currently line 135). Add no other member and no holder type. Acceptance: `Select-String -LiteralPath 'UtilitiesCS/Threading/UiThread.cs' -SimpleMatch 'DispatcherNotInitializedMessage'` returns exactly one line whose text also contains the token `internal const string`; and a search of the same file for the token `internal const string DispatcherNotInitializedMessage` returns exactly one line. The token `UiThread.Initialize()` is still present at line 142 in the getter's inline literal at this point; P1-T2 removes that literal and asserts the zero-hit condition. + +- [ ] [P1-T2] Rewrite the `UiThread.Dispatcher` getter in `UtilitiesCS/Threading/UiThread.cs` so it reads the backing field exactly once into a local, tests the local, throws `new InvalidOperationException(DispatcherNotInitializedMessage)` when the local is null, and returns that same local otherwise (C02, C06, C09-message, C20). Keep the declared type non-nullable `Dispatcher` and keep the private setter; this is not a public signature change. Add the C05 comment immediately above the throw, stating that `Initialize()` constructs and shows a hidden WinForms `SyncContextForm` and must run on the UI thread, so a lazy `Init()` from an arbitrary reader is deliberately avoided even though the sibling `UiSyncContext` and `AutoScaleFactor` accessors do self-heal. Add the C08 XML documentation on the property: a ``, a `` documenting the deliberate non-lazy contract, and an ``. Acceptance: a search of the file for the token `_dispatcher is null` returns zero lines; a search for the token `return _dispatcher;` returns zero lines; a search for the token `= _dispatcher;` returns exactly one line, which is the getter's single capture of the backing field into a local; a search for the token `///` returns at least three lines; and a search for the literal string `"The UI dispatcher has not been captured.` returns exactly one line, which is the constant declaration added by P1-T1. + +- [ ] [P1-T3] Add the failed-initialization re-arm to `UiThread.Init()` in `UtilitiesCS/Threading/UiThread.cs` (C03). Keep the single-shot latch check at line 36 before `Initialize()` runs, so two concurrent callers cannot both enter `Initialize()`. Wrap the `Initialize()` call in a `try` whose `catch` assigns a fresh `ThreadSafeSingleShotGuard` to the `_loaded` field and then rethrows the original exception unchanged with a bare `throw;`. Add a comment on the catch stating that it exists to re-arm the latch, not to absorb the failure, so the broad catch remains within the General Code Change Policy. Acceptance: a search of the file for the single-line token `_loaded = new ThreadSafeSingleShotGuard()` returns exactly two lines — the field initializer at the declaration and the re-arm inside the catch; and a search for the single-line token `throw;` returns exactly one line. + +- [ ] [P1-T4] Correct the comment and route the throw through the shared constant in `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` (C20). Replace the false clause at lines 57-59 — which states that `UiThread.Dispatcher` "is null outside a live host" — with text stating that the production fallback provider throws directly from `UiThread.Dispatcher`, so the local `dispatcher is null` guard is unreachable on the production path and covers only injected providers, which are typed `Func` and exist only in tests. Replace the message literal at lines 64-66 with `UiThread.DispatcherNotInitializedMessage`. Acceptance: a search of this file for the token `DispatcherNotInitializedMessage` returns exactly one line; a search of the whole `UtilitiesCS` project directory for the token `before yielding folder tree work` returns zero lines; and a search of this file for the token `is set-once state populated by` returns zero lines. + +- [ ] [P1-T5] Update the single breaking assertion in `UtilitiesCS.Test/Threading/UiThread_Tests.cs`. Change the `WithMessage` argument on line 152 from `"*UiThread.Initialize()*"` to `"*UiThread.Init()*"`. Do **not** rename the enclosing test method `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`; its fully-qualified name is quoted inside a `TestCaseFilter` expression in a committed #584 regression-testing evidence artifact and renaming would make that recorded command resolve to zero tests (SD4). Acceptance: a search of this file for the token `WithMessage("*UiThread.Init()*")` returns exactly one line; a search for the token `WithMessage("*UiThread.Initialize()*")` returns zero lines; and a search for the token `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` returns exactly one line. + +- [ ] [P1-T6] Apply the C23 lambda-capture change to `UtilitiesCS/Threading/ProgressTracker.cs` and `UtilitiesCS/Threading/ProgressTrackerAsync.cs`. In each file, replace the re-read `UiDispatcher = UiThread.Dispatcher,` inside the `ProgressViewer` object initializer at line 39 with the already-captured local, so the initializer reads `UiDispatcher = UiDispatcher,`. Do not change the capture at line 33 and do not change the unrelated viewer-dispatcher read later in `ProgressTracker.cs` at line 203. Acceptance: `Select-String -LiteralPath 'UtilitiesCS/Threading/ProgressTracker.cs' -SimpleMatch 'UiThread.Dispatcher'` returns exactly one line, which is line 33; the same search over `UtilitiesCS/Threading/ProgressTrackerAsync.cs` returns exactly one line, which is line 33. + +- [ ] [P1-T7] Remove the two dead null comparisons from `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` (C01). On line 72 and on line 115 replace `if (dispatcher != null && !dispatcher.CheckAccess())` with `if (!dispatcher.CheckAccess())`. Do not edit the XML-documentation prose at lines 54 and 93, which mentions `UiThread.Dispatcher` and `UiThread.cs`. Acceptance: a search of this file for the token `dispatcher != null` returns zero lines; a search for the token `if (!dispatcher.CheckAccess())` returns exactly two lines, up from zero before this task; and `git diff pre-782-base -- TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` shows exactly two changed hunks, each of one removed and one added line, with no hunk touching a line beginning with ` ///`. + +- [ ] [P1-T8] Run the analyzer build and the nullable build over the Phase 1 tree. Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true`, then `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true`. Write `evidence/qa-gates/p1-t8-phase1-builds.md` with `Timestamp:`, `Command:` carrying both command lines, `EXIT_CODE:` carrying a single integer that is the larger of the two exit codes, and `Output Summary:` quoting each build's `Warning(s)` and `Error(s)` lines separately. Acceptance: `EXIT_CODE: 0`, both builds recorded `0 Warning(s)` and `0 Error(s)`, and the re-armed latch added by P1-T3 introduced no analyzer diagnostic. + +- [ ] [P1-T9] Run the scoped test gate for Phase 1. Run vstest over `UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll`, `QuickFiler.Test\bin\Debug\QuickFiler.Test.dll`, and `TaskMaster.Test\bin\Debug\TaskMaster.Test.dll` with `/Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p1 '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'` — the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon — and the mandatory `/TestCaseFilter` expression. Write `evidence/qa-gates/p1-t9-phase1-tests.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting `Total tests:`, `Passed:`, `Failed:` and stating that these are locally-filtered figures over three assemblies, not CI figures and not the nine-assembly figure. Acceptance: `EXIT_CODE: 0` and `Failed: 0`. In particular `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` must appear in the TRX with outcome `Passed`, proving the P1-T5 assertion change matches the P1-T2 message change. + +- [ ] [P1-T10] Commit Phase 1 and verify commit hygiene. Stage the twenty-one paths this phase and Phase 0 produced — the five production files; `UtilitiesCS.Test/Threading/UiThread_Tests.cs`; the two Phase 1 evidence artifacts `evidence/qa-gates/p1-t8-phase1-builds.md` and `evidence/qa-gates/p1-t9-phase1-tests.md`; and the thirteen Phase 0 baseline artifacts `evidence/baseline/phase0-instructions-read.md`, `evidence/baseline/p0-t2-base-ref.md`, `evidence/baseline/p0-t3-csharpier-check.md`, `evidence/baseline/p0-t4-analyzer-build.md`, `evidence/baseline/p0-t5-nullable-build.md`, `evidence/baseline/p0-t6-vstest.md`, `evidence/baseline/p0-t7-coverage.md`, `evidence/baseline/p0-t8-line-counts.md`, `evidence/baseline/p0-t9-584-spec-rederivation.md`, `evidence/baseline/p0-t10-584-plan-rederivation.md`, `evidence/baseline/p0-t11-idle-serialization-census.md`, `evidence/baseline/p0-t12-exitcode-census.md`, and `evidence/baseline/p0-t13-reflection-census.md` — using explicit pathspecs, never `git add -A`. Phase 0 has no commit task of its own, so its evidence is carried by this commit; leaving it untracked would make the `docs/features/active` porcelain span in P7-T9 report thirteen `??` lines. Commit with a message naming issue #782 and findings C01, C02, C03, C05, C06, C08, C09-message, C20, C23. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines and in particular does not list `artifacts/orchestration/orchestrator-state.json`; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; and `git status --porcelain --untracked-files=all -- UtilitiesCS TaskMaster UtilitiesCS.Test QuickFiler.Test` returns zero lines. The `git status` span in this task is the companion required alongside the name-listing diffs, because a name-listing diff enumerates tracked changes only and cannot report a path this phase created; and `git ls-files --error-unmatch` exits 0 for each of the thirteen `evidence/baseline/` artifacts named above, proving the Phase 0 evidence is committed rather than merely present on disk. + +### Phase 2 — The ProgressTracker Test File Split (C16, C15) + +This phase runs before the C12/C13 migration (SD6), so the line arithmetic below is the measured +arithmetic over the current 514-line file and the migration is applied once, to the new file. + +- [ ] [P2-T1] Create `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs` holding the whole `#region P74 — ProgressTracker core Report/child/root-close behaviour` block, which is currently lines 270-512 of `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs`. The new file declares `public partial class ProgressTracker_Tests` inside `namespace UtilitiesCS.Test` and carries **no** class attributes, because `[TestClass]` is not `AllowMultiple` and applying it to two parts of the same partial class is a compile error. Copy the ten `using` directives from lines 1-10 of the source file. Move the region verbatim; change no test method name, no attribute, and no assertion. Immediately after creating the file, run the `DOTNET_ROOT` / `PATH` preamble and `dotnet tool run csharpier format UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, then re-run the line-count command on it and carry both the pre-format and post-format counts, and the exact format command, into `evidence/qa-gates/p2-t4-file-size.md` as that file's row when P2-T4 writes it. Formatting the file at creation time keeps it from being the file that rewrites the tree during P7-T1 and forces a second Phase 7 pass. Acceptance: the new file exists; `dotnet tool run csharpier format` was run against it and its exit code and post-format line count were captured for P2-T4; a search of it for the token `public partial class ProgressTracker_Tests` returns exactly one line; a search for the token `[TestClass]` returns zero lines; a search for the token `[DoNotParallelize]` returns zero lines; a search for `^\s*\[TestMethod\]` returns exactly 4 lines and for `^\s*\[STATestMethod\]` returns exactly 3 lines. + +- [ ] [P2-T2] Reduce `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` to the retained part. Delete the moved region (current lines 270-512). Replace the combined attribute line ` [TestClass, DoNotParallelize]` at line 14 with two separate attribute lines, ` [TestClass]` then ` [DoNotParallelize]` (C15). Change the class declaration to `public partial class ProgressTracker_Tests`. Retain the `CapturingProgressTracker` nested class, which every test in both parts uses. Acceptance: a search of this file for `^\s*\[TestMethod\]` returns exactly 17 lines and for `^\s*\[STATestMethod\]` returns zero lines; a search for the token `[TestClass, DoNotParallelize]` returns zero lines; searches for `^\s*\[TestClass\]$` and `^\s*\[DoNotParallelize\]$` each return exactly one line; a search for the token `public partial class ProgressTracker_Tests` returns exactly one line; and a search for the token `private sealed class CapturingProgressTracker` returns exactly one line. + +- [ ] [P2-T3] Register the new file in `UtilitiesCS.Test/UtilitiesCS.Test.csproj`. Insert exactly one `` element immediately after the existing `` element (currently line 477), matching the file's conventions: four-space indent, one self-closing element per line, Windows backslash separators, appended adjacent to its sibling rather than sorted. Add no other element and change no existing line. Duplicate `` entries are a known past defect in this project (CS2002, issue #394). Acceptance: a search of the csproj for the token `Threading\ProgressTracker_ReportAndViewerTests.cs` returns exactly one line; `git diff pre-782-base -- UtilitiesCS.Test/UtilitiesCS.Test.csproj` shows exactly one added line and zero removed lines. + +- [ ] [P2-T4] Gate the post-split file sizes and shapes. Run `(Get-Content -LiteralPath 'UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs').Count` and `(Get-Content -LiteralPath 'UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs').Count`. Write `evidence/qa-gates/p2-t4-file-size.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` recording both observed counts beside the projected counts of 271 and 260 respectively, together with the counting command, and, for `ProgressTracker_ReportAndViewerTests.cs`, the pre-format and post-format counts and the exact `csharpier format` command that P2-T1 ran against it. Acceptance: both observed counts are strictly less than 500 and strictly less than 300; and each observed count is within 5 lines of its projection (271 for `ProgressTracker_Tests.cs`, 260 for `ProgressTracker_ReportAndViewerTests.cs`). A deviation greater than 5 lines is recorded in the artifact with the reason before the task is marked complete. This gate is placed after the split; before the split it could not pass, because the source file is 514 lines. + +- [ ] [P2-T5] Prove that no test was lost by the split. Build with `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU"`, then run vstest over `UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll` with `/Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p2 '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None' /TestCaseFilter:"FullyQualifiedName~UtilitiesCS.Test.ProgressTracker_Tests"`, with the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon. Write `evidence/qa-gates/p2-t5-split-test-names.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` listing every executed test's fully-qualified name and outcome, read from the TRX `UnitTestResult` elements. Acceptance: `EXIT_CODE: 0`; the recorded list contains exactly 24 fully-qualified names, all beginning `UtilitiesCS.Test.ProgressTracker_Tests.`; every one has outcome `Passed`; and the list contains `UtilitiesCS.Test.ProgressTracker_Tests.Initialize_WithCurrentDispatcherAndScreen_InitializesViewerAndUpdatesUi` and `UtilitiesCS.Test.ProgressTracker_Tests.Increment_ShouldUpdateProgressAndForwardScaledValueAndJobName`, one from each part, proving the partial class was reassembled under the original names. + +- [ ] [P2-T6] Commit Phase 2 and verify commit hygiene. Stage only `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, `UtilitiesCS.Test/UtilitiesCS.Test.csproj`, and the two Phase 2 evidence artifacts, using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and findings C15 and C16. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; `git ls-files --error-unmatch UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs` exits 0, proving the new file is tracked rather than merely present on disk; and `git status --porcelain --untracked-files=all -- UtilitiesCS.Test` returns zero lines. + +### Phase 3 — The Shared Dispatcher Install Scope (C12, C13, C10, C11, C18, C19, C25) + +- [ ] [P3-T1] Create `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` declaring `internal sealed class UiThreadDispatcherScope : IDisposable` in `namespace UtilitiesCS.Test`, which is the only namespace all five consuming files can reach without a `using` directive. The file must open its type declaration region with `#nullable enable annotations` and close it with `#nullable restore annotations`, matching the idiom already used at `UtilitiesCS.Test/TestHelpers/ManualFireTimerWrapper.cs` lines 28 and 31 and, as measured against `pre-782-base`, at `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` lines 417 and 419. The Phase 2 split moves that second pair into `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, so at the time this task runs the untouched second precedent is `UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs` lines 671 and 679, which this delivery does not modify. Without the pragma pair every `Dispatcher?` annotation below raises `CS8632`, because no project in this repository carries a `` element and `/p:TreatWarningsAsErrors=true` in P3-T11 and P7-T4 promotes that warning to a build error. `enable annotations` rather than a bare `enable` is used so the file does not additionally opt into flow warnings that no other file in this assembly carries. The consumers and their namespaces are `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`, and `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` in `UtilitiesCS.Test.Threading`; `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs` in `UtilitiesCS.Test`; and `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` in `UtilitiesCS.Test.OutlookObjects.Folder`, which P4-T4 makes a consumer. The sibling helper `UtilitiesCS.Test/TestHelpers/ManualFireTimerWrapper.cs` uses `UtilitiesCS.Test.TestHelpers`; that convention is deliberately not followed here, because it would require a `using` directive in five files that no task adds. Its members are exactly: a `private static readonly FieldInfo` resolved once in a static initializer whose resolution asserts the field is non-null with a stated reason, mirroring the `ResolveDispatcherField` idiom at `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` lines 133-141, so a rename of `_dispatcher` raises `TypeInitializationException` and fails every consuming test rather than degrading to a silent no-op; `internal static Dispatcher? Current { get; }` reading the field directly so a test can observe the uninitialized state without triggering the property guard; `internal static UiThreadDispatcherScope Install(Dispatcher? replacement)` capturing the prior value, writing the replacement, and returning the scope; `internal static UiThreadDispatcherScope InstallNull()` as a convenience for `Install(null)`; and `void Dispose()` restoring the captured prior value **including a null prior value**, storing the prior in a nullable field and never testing it for null before restoring, with a second `Dispose()` call being a no-op. The type is deliberately not internally synchronized; its XML documentation must state that serialization of writers is provided by `[DoNotParallelize]` on every class that installs a value, so a future caller does not assume thread safety. Immediately after creating the file, run the `DOTNET_ROOT` / `PATH` preamble and `dotnet tool run csharpier format UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs`, then re-run the line-count command on it and carry both the pre-format and post-format counts, and the exact format command, into `evidence/qa-gates/p4-t10-file-size.md` as that file's row when P4-T10 writes it. Formatting the file at creation time keeps it from being the file that rewrites the tree during P7-T1 and forces a second Phase 7 pass. Acceptance: the file exists; `dotnet tool run csharpier format` was run against it and its exit code and post-format line count were captured for P4-T10; a search of it for the token `GetField(` returns exactly one line; a search of the file for the token `namespace UtilitiesCS.Test` returns exactly one line, whose text does not contain `UtilitiesCS.Test.TestHelpers`; a search for the token `internal sealed class UiThreadDispatcherScope` returns exactly one line; searches for the tokens `internal static Dispatcher? Current`, `InstallNull`, and `public void Dispose()` each return at least one line; and a search for the token `[DoNotParallelize]` returns at least one line, which is inside the XML documentation; a search of the file for the token `#nullable enable annotations` returns exactly one line and a search for the token `#nullable restore annotations` returns exactly one line, and the `internal static Dispatcher? Current` line lies between them. + +- [ ] [P3-T2] Register the new helper in `UtilitiesCS.Test/UtilitiesCS.Test.csproj`. Insert exactly one `` element immediately after the existing `` element (currently line 75), matching the file's conventions. Acceptance: a search of the csproj for the token `TestHelpers\UiThreadDispatcherScope.cs` returns exactly one line; `git diff pre-782-base -- UtilitiesCS.Test/UtilitiesCS.Test.csproj` shows exactly two added lines in total across Phases 2 and 3 and zero removed lines. + +- [ ] [P3-T3] Migrate `UtilitiesCS.Test/Threading/UiThread_Tests.cs` to the install scope and fix C10 and C11. Delete the private `DispatcherField()` helper at lines 125-131 and both hand-rolled capture / `SetValue` / `try` / `finally` blocks, replacing each with a `using` statement over `UiThreadDispatcherScope`. In `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`, install null through `UiThreadDispatcherScope.InstallNull()` and change the block-bodied assertion lambda at lines 144-147 to the expression-bodied form `Action act = () => _ = UiThread.Dispatcher;` (C11). In `Dispatcher_WhenBackingFieldIsPopulated_ReturnsThatSameInstance`, stop calling `Dispatcher.CurrentDispatcher` on the pooled MTA worker (C10): obtain the sentinel dispatcher from a dedicated STA thread modelled on the `StaDispatcherHost` nested class at `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` lines 172-199, which starts a background STA thread, captures `Dispatcher.CurrentDispatcher`, runs `Dispatcher.Run()`, and in `Dispose()` calls `BeginInvokeShutdown(DispatcherPriority.Send)`, joins the thread, and disposes its ready event. Establish the null prior explicitly with an outer `using (UiThreadDispatcherScope.InstallNull())`, then install the sentinel through an inner `using (UiThreadDispatcherScope.Install(...))`, assert inside the inner scope that `UiThread.Dispatcher` is the same instance, and after the inner scope is disposed assert that `UiThreadDispatcherScope.Current` is null again, which is the round-trip restore assertion AC5 requires. The outer `InstallNull()` is required rather than relying on the ambient value: `QuickFiler.Test/Controllers/QfcHomeControllerRunAsyncTests.cs` line 329 calls `UiThread.Init(false)`, which populates the same process-global static, and P3-T11, P4-T11, and P7-T5 all run `QuickFiler.Test` and `UtilitiesCS.Test` in one vstest invocation, so an ambient non-null prior would be restored by the inner disposal and the assertion would fail for a reason outside this delivery. The STA host is constructed inside a `using` statement so that `BeginInvokeShutdown` and the thread join run on every exit path, including a failing assertion. Create no temporary file. Acceptance: a search of this file for the token `GetField(` returns zero lines; a search of the migrated populated-branch test for the token `using (` or the token `using var` returns at least one line covering the STA host's lifetime; a search for the token `Dispatcher.CurrentDispatcher` returns exactly one line, which is inside the STA host's thread body; searches for the tokens `BeginInvokeShutdown` and `.Join()` each return at least one line; a search for the token `UiThreadDispatcherScope` returns at least three lines; a search of the migrated populated-branch test for the token `UiThreadDispatcherScope.InstallNull()` returns exactly one line, which is the outer scope establishing the null prior; and both test methods retain their exact original names. + +- [ ] [P3-T4] Refresh the stale class documentation in `UtilitiesCS.Test/Threading/UiThread_Tests.cs`. Rewrite the `` block currently at lines 106-120 so it describes the seam as it exists after P3-T3: the shared `UiThreadDispatcherScope` install scope, the fact that reflection remains because `InternalsVisibleTo` does not expose private members, and the fact that the accessor now throws `InvalidOperationException` synchronously rather than returning null. The rewritten prose must name the public entry point `UiThread.Init()`. Acceptance: a search of this file for the token `UiThread.Initialize()` returns zero lines; a search for the token `UiThread.Init()` returns at least one line; and a search for the token `capture the prior field value and put it back in a finally block` returns zero lines, because that description is false after the migration. + +- [ ] [P3-T5] Migrate the reflection site in `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`. Replace the `dispatcherField` acquisition, the `previousDispatcher` capture, the `SetValue` inside the `try`, and the `SetValue` in the `finally` — which arrived from `ProgressTracker_Tests.cs` lines 421-426, 432, and 450 by the Phase 2 split — with a single `using` statement over `UiThreadDispatcherScope.Install(currentDispatcher)`. Leave the `SynchronizationContext` capture and restore, the viewer close in the `finally`, and every assertion unchanged. Acceptance: a search of this file for the token `GetField(` returns zero lines; a search for the token `dispatcherField` returns zero lines; a search for the token `UiThreadDispatcherScope.Install` returns exactly one line; and the test `Initialize_WithCurrentDispatcherAndScreen_InitializesViewerAndUpdatesUi` retains its exact name. + +- [ ] [P3-T6] Migrate the reflection site in `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`. Replace the `dispatcherField` acquisition at lines 138-141, its `Should().NotBeNull()` guard at line 142, the `previousDispatcher` capture at line 145, the `SetValue` at line 151, and the matching restore in the `finally` with a single `using` statement over `UiThreadDispatcherScope.Install(currentDispatcher)` inside the existing STA thread body. Leave the STA thread construction, the `DispatcherFrame` pump, the `threadException` capture, and every assertion unchanged. Acceptance: a search of this file for the token `GetField(` returns zero lines; a search for the token `dispatcherField` returns zero lines; a search for the token `UiThreadDispatcherScope.Install` returns exactly one line. + +- [ ] [P3-T7] Reimplement the dispatcher helpers in `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` over the install scope and rewrite their documentation (C12, C13, SD14). Delete the `DispatcherField()` helper at lines 142-148 and reimplement `ForceDispatcherNull` (lines 165-171) and `RestoreDispatcher` (lines 184-187) so that the null installation and its restoration are performed by `UiThreadDispatcherScope`, or replace both helpers with a `using` over `UiThreadDispatcherScope.InstallNull()` at each call site. Rewrite the `` block at lines 150-164 so the surviving documentation describes the post-#778 mechanism: reading `UiThread.Dispatcher` while the backing field is null throws `InvalidOperationException` synchronously, and the public entry point that populates the field is `UiThread.Init()`. This supersedes the `spec.md` Constraint 8 clause that leaves lines 155-160 untouched, per SD14; P6-T1 records the supersession. Acceptance: a search of this file for the token `GetField(` returns zero lines; a search for the token `UiThread.Initialize()` returns zero lines; a search for the token `UiThreadDispatcherScope` returns at least one line; and a search of the rewritten `` block for the token `InvalidOperationException` returns at least one line, and for the token `UiThread.Init()` returns at least one line. A zero-hit condition on `NullReferenceException` inside this block is deliberately not asserted: the token does not occur anywhere in lines 150-164 today, occurring only at lines 238 and 267, which are P3-T8's spans, so such a condition would hold before and after this task and could not fail. + +- [ ] [P3-T8] Rewrite the three P27-T2 passages in `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` to describe the synchronous `InvalidOperationException` path (C19). The three passages are the `` Scenario text at lines 236-240, the Act comment at lines 266-267, and the `NotThrow` reason string at line 272. The correct mechanism, verified in production source: `UtilitiesCS/Threading/IdleAsyncQueue.cs` line 72 reads `UiThread.Dispatcher` inside the `try` opened at line 68 and before the first await completes, so the getter throws `InvalidOperationException` synchronously and it is swallowed by the `catch (Exception ex)` at line 83; the entry is dequeued at line 65, before the `try`, which is why the `Count == 0` assertion still holds. Acceptance: a search of this file for the token `NullReferenceException` returns zero lines; a search for the token `InvalidOperationException` returns at least three lines; and the `NotThrow` reason string on the rewritten line contains the single-line token `InvalidOperationException`. + +- [ ] [P3-T9] Migrate `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` to the existing fixture accessor (C18, C25). `UtilitiesCS.Test`'s scope is not reachable from `QuickFiler.Test`, because `UtilitiesCS/Properties/AssemblyInfo.cs` grants `InternalsVisibleTo` only to `DynamicProxyGenAssembly2`, `UtilitiesCS.Test`, and `ToDoModel.Test`. Delete the local `private static readonly System.Reflection.FieldInfo DispatcherField` declaration at lines 39-43 and replace both null-conditional reads — `DispatcherField?.GetValue(null)` at line 55 and at line 64 — with `UiThreadDispatcherFixture.Current`, adding `using QuickFiler.Controllers.Tests;` or using a qualified reference, because `EmailMoveMonitorTests` is in namespace `QuickFiler.Helper_Classes.Tests`. Retype the snapshot field `private object _capturedDispatcher;` at line 38 to `private Dispatcher _capturedDispatcher;`, and add `using System.Windows.Threading;` or spell the type as `System.Windows.Threading.Dispatcher`, because this file carries no such directive today; WindowsBase is already referenced by `QuickFiler.Test.csproj`, so no project reference is added. Delete the two "avoid WindowsBase" comment clauses, at line 29 and at line 53 (C25), while retaining the accurate paragraph at lines 33-37 verbatim. Acceptance: a search of this file for the token `GetField(` returns zero lines; a search for the token `avoid WindowsBase` returns zero lines; a search for the token `avoiding a compile-time WindowsBase dependency` returns zero lines; a search for the token `UiThreadDispatcherFixture.Current` returns exactly two lines; and a search for the token `PropertyInfo.GetValue would` returns exactly one line, proving the accurate paragraph survived. + +- [ ] [P3-T10] Gate the AC5 reflection-site reduction. Search all `*.cs` files repository-wide for the single-line token `"_dispatcher"`. Write `evidence/qa-gates/p3-t10-reflection-sites.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` listing every hit with its file and line number, alongside the six-site before-figure recorded in `evidence/baseline/p0-t13-reflection-census.md`. Acceptance: the search returns exactly two lines, reduced from the six recorded in `evidence/baseline/p0-t13-reflection-census.md`; one is in `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` and the other in `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs`; and both `git diff --name-only pre-782-base..HEAD -- QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` and `git status --porcelain --untracked-files=all -- QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` return zero lines, proving the surviving QuickFiler.Test fixture was neither committed nor left modified in the worktree by this delivery. The porcelain span is required alongside the diff because Phase 3 is not yet committed when this task runs, so the diff alone could not observe an uncommitted modification. + +- [ ] [P3-T11] Run the Phase 3 build and scoped test gate. Run the analyzer build and the nullable build as in P1-T8, then vstest over `UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll` and `QuickFiler.Test\bin\Debug\QuickFiler.Test.dll` with `/Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p3 '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'` — the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon — and the mandatory `/TestCaseFilter`. Write `evidence/qa-gates/p3-t11-phase3-gate.md` with `Timestamp:`, `Command:` carrying all three command lines, `EXIT_CODE:` carrying a single integer that is the largest of the three exit codes, and `Output Summary:` quoting both builds' `Warning(s)` and `Error(s)` lines and the test run's `Total tests:`, `Passed:`, and `Failed:` values, stated as locally-filtered figures over two assemblies. Acceptance: `EXIT_CODE: 0`, both builds recorded `0 Warning(s)` and `0 Error(s)`, and `Failed: 0`. + +- [ ] [P3-T12] Commit Phase 3 and verify commit hygiene. Stage only the files this phase touched — `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs`, `UtilitiesCS.Test/UtilitiesCS.Test.csproj`, `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`, `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs`, `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs`, and the two Phase 3 evidence artifacts — using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and findings C10, C11, C12, C13, C18, C19, C25. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; `git ls-files --error-unmatch UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` exits 0; and `git status --porcelain --untracked-files=all -- UtilitiesCS.Test QuickFiler.Test` returns zero lines. + +### Phase 4 — Test Hygiene, New Regression Tests, and Fail-Before Evidence + +- [ ] [P4-T1] Add the cleanup and the serialization attribute to `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs` (C14, SD7). Add `[DoNotParallelize]` immediately below the existing `[TestClass]` at line 24, matching the two-separate-lines form used by every sibling and by `ApplicationIdleTimer_Tests` at lines 16-17. Add a `[TestCleanup]` method that drains the queued entries by setting the static `_entries` field to null so the `Entries` getter lazily recreates it, replaces `_subscribeGuard` with a fresh `ThreadSafeSingleShotGuard`, calls `CancelAction()` on `_unsubscribe` and nulls the `TimedBatchAction._timer` reference, and unsubscribes the heartbeat handler by calling `ApplicationIdleTimer.Unsubscribe` with a delegate rebuilt through `Delegate.CreateDelegate` over `IdleActionQueue.OnApplicationIdle`. The existing private `ResetStaticState()` helper at lines 39-69 already performs the first three actions and must be reused rather than duplicated. The attribute is required because `ApplicationIdleTimer.Unsubscribe` calls `Stop()` when the invocation list empties, which touches process-global `System.Windows.Forms.Application.Idle` and `ApplicationIdleTimer.Guard` state shared with `IdleAsyncQueue_Tests` and `ApplicationIdleTimer_Tests`; `evidence/baseline/p0-t11-idle-serialization-census.md` records that both of those classes are already `[DoNotParallelize]` and this one is not. Create no temporary file. Acceptance: searches of this file for `^\s*\[TestClass\]$` and `^\s*\[DoNotParallelize\]$` each return exactly one line, and the `[DoNotParallelize]` line number is exactly one greater than the `[TestClass]` line number; a search for the token `[TestCleanup]` returns exactly one line; a search for the token `ApplicationIdleTimer.Unsubscribe` returns exactly one line; and a search for the token `ResetStaticState()` returns exactly six lines, one more than the five present before this task, the additional line being the call from the new `[TestCleanup]` method. + +- [ ] [P4-T2] Correct the false clause in the Arrange comment at `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs` lines 121-127 (S2-1). The clause `neither of which can complete an InvokeAsync` at lines 124-125 is false after PR #778: the unset case no longer reaches `InvokeAsync` at all, because the `UiThread.Dispatcher` getter throws `InvalidOperationException` first. Replace it with wording that distinguishes the two cases — the unset case throws from the accessor before any marshalling occurs, and the parked case is a real dispatcher that never pumps — while preserving the rest of the comment, including the reference to `WinFormsPumpHostTests.BothMarshalRoutes_*` and the `PumpHarness.Restore` sentence. Do not edit the `UiThread.Dispatcher` mentions at lines 52 and 308. Acceptance: a search of this file for the single-line token `neither of which can` returns zero lines — the full clause is not searchable, because CSharpier wraps it across lines 124 and 125 and a line-oriented search for it returns zero lines before the edit as well; a search for the token `InvalidOperationException` returns at least one line inside the comment block beginning at line 121; and a search for the token `PumpHarness.Restore` returns exactly two lines, one of which is inside the comment block beginning at line 121. The second `PumpHarness.Restore` line is at line 51, outside the edited block and untouched by this task, so an at-least-one condition could not fail. + +- [ ] [P4-T3] Strengthen the C20 assertion in `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`. Add a `WithMessage("*UiThread.Init()*")` to the `ThrowAsync()` assertion at lines 131-134 inside `YieldAsync_WithoutDispatcher_RemainsStrict`, pinning the shared constant's text. Leave the two `InvocationCount` assertions unchanged. Additionally correct the stale reference at line 122, replacing `UiThread.Initialize()` with `UiThread.Init()`, so this file carries no reference to the private method after the C06 change; `spec.md` Constraint 8 names that occurrence but assigns it no disposition, and this file is already in the write set. Acceptance: a search of this file for the token `WithMessage("*UiThread.Init()*")` returns at least one line; a search of this file for the token `UiThread.Initialize()` returns zero lines, down from the one line present at line 122 before this task; the test `YieldAsync_WithoutDispatcher_RemainsStrict` retains its exact name; and the two `InvocationCount.Should()` assertions are unchanged in `git diff pre-782-base -- "UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs"`. + +- [ ] [P4-T4] Add the C21 production-fallback test to `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`, named exactly `YieldAsync_ProductionFallbackWithoutDispatcher_ThrowsNamingInit`, and add `[DoNotParallelize]` to the class immediately below the existing `[TestClass]` at line 12. The attribute is required, not optional: this is the first test in the class that installs a value into the process-global `UiThread._dispatcher` static, and `UiThreadDispatcherScope`'s documented contract is that serialization of writers comes from `[DoNotParallelize]` on every installing class. The new test must construct `new WpfDispatcherYield()` through the public parameterless constructor (lines 21-22), so the fallback provider is the production `() => UtilitiesCS.UiThread.Dispatcher`, and must run its Act on a dedicated fresh thread that never touches `Dispatcher.CurrentDispatcher`, joining that thread before asserting. A fresh thread is required rather than `[DoNotParallelize]` alone: on a pooled MSTest worker `Dispatcher.FromThread` returns non-null if any earlier test on that same thread ever touched `CurrentDispatcher`, which would make the thread-affinitized provider win and the fallback never run. Install null through `using (UiThreadDispatcherScope.InstallNull())` around the thread's lifetime, observe the exception on the worker thread by calling `.GetAwaiter().GetResult()` on the task returned by `YieldAsync`, capture it into a local, join, and assert on the test thread that it is an `InvalidOperationException` whose message contains the token `UiThread.Init()`. Create no temporary file. Acceptance: searches of this file for `^\s*\[TestClass\]$` and `^\s*\[DoNotParallelize\]$` each return exactly one line; a search for the token `YieldAsync_ProductionFallbackWithoutDispatcher_ThrowsNamingInit` returns exactly one line; a search for the token `new WpfDispatcherYield()` returns exactly one line; a search for the token `UiThreadDispatcherScope.InstallNull()` returns exactly one line; a search for the token `.Join()` returns at least one line; and a search for the token `Dispatcher.CurrentDispatcher` in the new test body returns zero lines. + +- [ ] [P4-T5] Add the C26 asynchronous test to `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`, named `InitializeAsync_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`. `ProgressTrackerAsync.InitializeAsync` is declared `public async Task` at `UtilitiesCS/Threading/ProgressTrackerAsync.cs` line 31, so the guarded read at line 33 faults the returned task rather than throwing at the call site (SD8). The test must therefore be written as `Func act = () => tracker.InitializeAsync();` followed by `await act.Should().ThrowAsync();`. A synchronous `Should().Throw<...>()` assertion would fail. Install null through `using (UiThreadDispatcherScope.InstallNull())`. Acceptance: a search of this file for the token `InitializeAsync_WhenDispatcherNotCaptured_ThrowsInvalidOperationException` returns exactly one line; a search for the token `ThrowAsync` returns at least one line; a search of the new test body for the token `Should().Throw` returns zero lines; and a search for the token `UiThreadDispatcherScope.InstallNull()` returns at least one line. + +- [ ] [P4-T6] Add the C26 synchronous sibling test to `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, named `Initialize_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`. `ProgressTracker.Initialize()` is declared `public virtual ProgressTracker` at `UtilitiesCS/Threading/ProgressTracker.cs` line 31 and is not async, so it does throw synchronously from line 33 and a plain `Should().Throw()` is correct. Install null through `using (UiThreadDispatcherScope.InstallNull())`. This closes C26's second named gap. Acceptance: a search of this file for the token `Initialize_WhenDispatcherNotCaptured_ThrowsInvalidOperationException` returns exactly one line; a search for the token `Should().Throw` returns at least one line; and a re-run of the P2-T4 counting command on this file reports a count strictly less than 500. + +- [ ] [P4-T7] [expect-fail] Demonstrate the fail-before state for the three new AC7 tests. Make exactly two temporary source edits and record both verbatim in the artifact before running anything: in `UtilitiesCS/Threading/UiThread.cs`, replace the getter's null test and throw with a bare `return _dispatcher!;`; and in `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`, comment out the whole `if (dispatcher is null) { throw ...; }` block. **Both edits are required together for the C21 demonstration**: removing only the `UiThread` throw leaves the sibling guard in `WpfDispatcherYield`, which throws the same exception type with the same constant, so the C21 test would still pass and the demonstration would be vacuous. Build with `msbuild TaskMaster.sln /t:Build /m /p:Configuration=Debug "/p:Platform=Any CPU"` — the plain build, without `/p:TreatWarningsAsErrors=true`, because the temporary edits raise nullable-flow warnings that are expected and must not fail this build. Then run vstest over `UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll` with `/Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p4-failbefore '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'` — the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon — and `/TestCaseFilter:"FullyQualifiedName~YieldAsync_ProductionFallbackWithoutDispatcher_ThrowsNamingInit|FullyQualifiedName~InitializeAsync_WhenDispatcherNotCaptured_ThrowsInvalidOperationException|FullyQualifiedName~Initialize_WhenDispatcherNotCaptured_ThrowsInvalidOperationException"`. That filter selects exactly three tests: the `~` operator is a substring match, and `InitializeAsync_WhenDispatcherNotCaptured_ThrowsInvalidOperationException` does not contain the substring `Initialize_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`, so the two C26 clauses do not overlap. Write `evidence/regression-testing/p4-t7-fail-before.md` with `Timestamp:`, `Command:` carrying the build and test command lines, `EXIT_CODE: 1`, `ExpectedExitCode: 1`, and `Output Summary:` carrying the two temporary edits verbatim, the three fully-qualified test names, each test's outcome and its verbatim failure message read from the TRX, and a statement that these are locally-filtered figures. Acceptance: `Total tests: 3`, `Passed: 0`, `Failed: 3`, and each of the three recorded failure messages names an exception type other than `InvalidOperationException` or reports that no exception was thrown, proving the failure is attributable to the removed guards and not to a harness defect. + +- [ ] [P4-T8] Restore the two temporary edits and demonstrate the pass-after state. Revert `UtilitiesCS/Threading/UiThread.cs` and `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` to their committed Phase 1 content with `git checkout HEAD -- UtilitiesCS/Threading/UiThread.cs UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`. Rebuild with the same plain build command and re-run the same three-test filter into `/ResultsDirectory:TestResults\782-p4-passafter`. Write `evidence/regression-testing/p4-t8-pass-after.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` carrying the three fully-qualified test names with outcome `Passed`, and stating that these are locally-filtered figures. Acceptance: `EXIT_CODE: 0`; `Total tests: 3`, `Passed: 3`, `Failed: 0`; and `git status --porcelain --untracked-files=all -- UtilitiesCS/Threading/UiThread.cs UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` returns zero lines, proving both files match their committed content exactly and the temporary edits left no residue. The porcelain span rather than a diff is the correct check here, because the two files are already committed at their Phase 1 content and the question is whether the worktree still matches that commit. + +- [ ] [P4-T9] Write the fail-before exception dossier for C10 and C02 (SD13). Neither hazard yields a deterministic in-suite failing test, so a failing run is recorded as structurally impossible rather than asserted. Write `evidence/regression-testing/fail-before-exception..md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, `Output Summary:`, a `WhyFailingRunImpossible:` field, and an alternative proof section. `WhyFailingRunImpossible:` must state that C10's hazard is a leaked, never-shut dispatcher on a pooled MTA worker that manifests only when a later test on that same pooled thread resolves `Dispatcher.FromThread`, which is order-dependent and would violate the test-independence requirement of the General Unit Test Policy; and that C02's hazard is a torn double read of a non-volatile static, whose failing interleaving cannot be forced without a timing construct that the same policy prohibits. The alternative proof section must carry: for C10, the verbatim pre-change source of `Dispatcher_WhenBackingFieldIsPopulated_ReturnsThatSameInstance` showing `Dispatcher.CurrentDispatcher` called at line 166 inside a plain `[TestMethod]` with no shutdown, alongside the post-change source showing the STA host with `BeginInvokeShutdown` and `Join`; and for C02, the verbatim pre-change getter showing the two separate reads of `_dispatcher` at lines 139 and 145, alongside the post-change getter showing the single read into a local. Acceptance: the file exists under `evidence/regression-testing/` with a name beginning `fail-before-exception.`; it carries all of `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`, and `WhyFailingRunImpossible:`; and both alternative-proof subsections quote pre-change and post-change source. + +- [ ] [P4-T10] Gate the file sizes of every touched test file. Run `(Get-Content -LiteralPath '').Count` over all ten test files in the Write Set plus `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs`. Write `evidence/qa-gates/p4-t10-file-size.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` recording one row per file carrying the counting command, the baseline count from `evidence/baseline/p0-t8-line-counts.md` where one exists, and the observed count; the `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` row additionally carries the pre-format and post-format counts and the exact `csharpier format` command that P3-T1 ran against it. Acceptance: every observed count is strictly less than 500; and `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` and `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs` are each strictly less than 350, which is the headroom the Phase 2 arithmetic established. + +- [ ] [P4-T11] Run the Phase 4 build and full nine-assembly test gate. Run the analyzer build and the nullable build as in P1-T8, then vstest over all nine assembly paths with `/Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p4 '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None'` — the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon — and the mandatory `/TestCaseFilter`. `/EnableCodeCoverage` is deliberately not passed, for the reason stated in P0-T6. Write `evidence/qa-gates/p4-t11-phase4-gate.md` with `Timestamp:`, `Command:` carrying all three command lines, `EXIT_CODE:` carrying a single integer that is the largest of the three exit codes, and `Output Summary:` quoting both builds' `Warning(s)` and `Error(s)` lines and the test run's `Total tests:`, `Passed:`, `Failed:`, and `Skipped:` values, stated as locally-filtered figures over nine assemblies, not CI figures. Acceptance: `EXIT_CODE: 0`; both builds recorded `0 Warning(s)` and `0 Error(s)`; `Failed: 0`; and `Total tests:` is at least the baseline total recorded in `evidence/baseline/p0-t6-vstest.md` plus three, which is 6995 for the tabled baseline of 6992, because this delivery adds three new tests and removes none. If the only failure is `TryAddValuesAsync_UpdatesExistingValue`, record it as the known issue #780 flake, re-run once, and record both runs. + +- [ ] [P4-T12] Commit Phase 4 and verify commit hygiene. Stage only the files this phase touched — `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs`, `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs`, `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, and the Phase 4 evidence artifacts — using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and findings C14, C21, C26, S2-1 and the C20 assertion. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; `git status --porcelain --untracked-files=all -- UtilitiesCS UtilitiesCS.Test QuickFiler.Test TaskMaster` returns zero lines; and `git ls-files --error-unmatch` succeeds for every artifact written in Phase 4 under `evidence/regression-testing/` and `evidence/qa-gates/`. + +### Phase 5 — #584 Documentation and Evidence Corrections + +Every edit in this phase is made in place. No #584 evidence file is renamed and no existing +`Timestamp:` value is altered. + +Every line number cited in this phase is the pre-edit number measured against the current tree. +Several tasks edit more than one span in the same file, so a line number cited by a later task can +have shifted by the time that task runs. Locate every span by the token or clause this plan quotes +for it and treat the line number as a starting hint rather than as the address. + +- [ ] [P5-T1] Apply the S3-6 Status change to `#584/spec.md`. Replace the `Draft` token at the start of the `- **Status:**` value on line 7 with `Merged (PR #778, merge commit 1c3b210c, 2026-09-04)`, retaining the existing amendment-history sentence that follows it and leaving `- **Version:** 0.5` unchanged. The date is the author and committer date of `1c3b210c`, both `2026-09-04`; 2026-09-05 is this delivery's date, not the merge date. Do not alter any acceptance-criteria checkbox: `evidence/baseline/p0-t9-584-spec-rederivation.md` records that all seven already carry `[x]`, so the Status change is the only edit this block needs. Acceptance: a search of `#584/spec.md` for `^- \*\*Status:\*\* Draft` returns zero lines; a search for the token `Merged (PR #778, merge commit 1c3b210c, 2026-09-04)` returns exactly one line; and a search for `^- \[[ x]\] AC` returns exactly seven lines, all carrying `[x]`, unchanged from the P0-T9 record. + +- [ ] [P5-T2] Reconcile the three disagreeing file lists in `#584/spec.md` against the authoritative six-file Write Set (S3-6). List 1, "In scope" at lines 62-69, currently names three files; extend it to the six paths recorded in the P4-T1 owned-file list re-derived by P0-T10. List 2, "Files/modules to change" at lines 160-163, currently names two files; replace its independent enumeration with a cross-reference to the document's own `## Write Set` section rather than a third list. Cite that section by its heading text and not by line number: the three bullets this task inserts into list 1 sit above it and shift it from lines 86-95 to lines 89-98, so any line number written here would be wrong the moment it is written. Leave the Write Set itself unchanged. Acceptance: a search of `#584/spec.md` for the token `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` returns exactly seven lines, up from the six present before this task, the added line being the new list 1 bullet; a search for the token `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs` returns exactly five lines, up from the four present before this task, the added line being the new list 1 bullet; and the `#### Files/modules to change` section contains the single-line token `Write Set` and no line containing `.cs`. The before-counts are measured against the current tree: the two tokens occur on lines 46, 92, 126, 234, 239, and 288, and on lines 77, 93, 291, and 395 respectively. An at-least-two condition is deliberately not used, because both tokens already satisfy it before this task runs. + +- [ ] [P5-T3] Replace the three call-site figures in `#584/spec.md` (S3-7, SD10). The three locations are line 50 ("~40 other call sites"), lines 73-74 ("~62 remaining direct reads ... ~29 files"), and line 172 ("~40 call sites"). Those are the pre-edit line numbers, measured against the current tree. P5-T2 inserts three bullets into list 1 and replaces the two bullets of list 2 with a single cross-reference line, so by the time this task runs the second and third locations have shifted downward by an amount that depends on how many lines the cross-reference occupies. Locate each of the three by its quoted token rather than by line number. Replace each with the verified figure, worded as: 49 live reads across 25 production files, measured against the `pre-782-base` tag under issue #782, with 64 textual occurrences across 30 files of which 15 are comments, XML documentation, commented-out code, or the exception message literal. The measurement basis is stated as `pre-782-base` rather than as a date because P1-T6 removes two of those live reads in Phase 1, so a figure presented as current at Phase 5 write time would be wrong by two; naming the base commit makes the figure true and stable. Acceptance: searches of `#584/spec.md` for the tokens `~40 other call sites`, `~62 remaining direct reads`, and `~40 call sites` each return zero lines; and a search for the token `49 live reads across 25 production files` returns exactly three lines. The 25-versus-26 divergence against the review body is recorded in the code-review artifact by P6-T1, not here. + +- [ ] [P5-T4] Soften the four ordering passages that the recorded timestamps contradict (S3-1). The four locations are `#584/evidence/regression-testing/p1-t4-expect-fail.md` line 48, `#584/evidence/qa-gates/p3-t1-analyzer-build.md` lines 30-31, `#584/feature-audit.2026-09-04T04-05.md` lines 37-39, and `#584/policy-audit.2026-09-04T04-05.md` line 115. In each case remove the assertion that one artifact's run preceded another's and replace it with the same substantive claim stated without an ordering assertion: the sibling build recorded a clean `0 Error(s)` result over the same tree state, the two artifacts' recorded `Timestamp:` values do not establish their relative execution order, and the conclusion does not depend on the order because the sibling positive test passed in the same run. Note that the passage at `p3-t1-analyzer-build.md` lines 30-31 wraps across two lines, so a single-line search for it returns nothing; edit by line number. `#584/policy-audit.2026-09-04T04-05.md` line 115 is edited by this task alone and no other, so this task also removes the evaluative intensifier on that same line: the span `provable assertion-level` is replaced with an unmodified statement of the same claim, because `provable` is an evaluative intensifier over an already-evidenced statement and `.claude/rules/tonality.md` prohibits it. P5-T12 therefore owns six spans, not seven, and does not touch line 115. The same intensifier occurs a second time, at line 272 of the `#584` feature-audit artifact `feature-audit.2026-09-04T04-05.md`, in the clause `a provable assertion-level fail-before`. This task removes that span as well, replacing `provable assertion-level` with an unmodified statement of the same claim, so that no occurrence of the token survives in any of the four audit artifacts. Line 272 is the pre-edit number; this task's own softening of feature-audit lines 37-39 can shift it, so locate the span by its quoted clause rather than by line number. Acceptance: a search of the four files for the token `immediately before this run` returns zero lines; a search of the same four files for the single-line token `first build that` returns zero lines — the longer phrase `first build that compiles` is not used, because it wraps across lines 30 and 31 of `p3-t1-analyzer-build.md` and a line-oriented search for it returns zero lines before the edit as well, and the search is scoped to the four files because `#584/plan.2026-09-02T09-02.md` line 913 carries the same token and is not edited by this delivery; a search for the token `had just built with` returns zero lines; a search for the token `was clean, so this is an assertion-level RED` returns zero lines; a search of `#584/policy-audit.2026-09-04T04-05.md` for the token `provable assertion-level` returns zero lines; a search of the `#584` feature-audit artifact for the token `provable assertion-level` returns zero lines; and a search of the four files for the token `do not establish their relative execution order` returns exactly four lines. + +- [ ] [P5-T5] Correct the two formatter command cells (S3-2). The two locations are `#584/policy-audit.2026-09-04T04-05.md` line 229 and `#584/feature-audit.2026-09-04T04-05.md` line 149, both of which record the command as `dotnet tool run csharpier format .`. What actually ran, recorded verbatim at `#584/evidence/qa-gates/p4-t1-format.md` line 8 and re-derived by P0-T10 from the plan's P4-T1 block, is `dotnet tool run csharpier format` with six explicit path operands and no `.` operand. Replace each cell's command with the scoped six-path form. Leave the adjacent result cells, which record `Formatted 6 files`, unchanged, because that figure is CSharpier's processed-file count for the six operands and remains accurate. Acceptance: a search of `#584/policy-audit.2026-09-04T04-05.md` for the token `| Format (apply) | ` returns exactly one line, and that line does not contain the token `csharpier format .`; a search of `#584/feature-audit.2026-09-04T04-05.md` for the token `| 1. Format | ` returns exactly one line, and that line does not contain the token `csharpier format .`; and both lines contain the token `UtilitiesCS/Threading/UiThread.cs`. + +- [ ] [P5-T6] Amend row 3.1 and label the Appendix B entry (S3-2). Append to the evidence cell of row 3.1 at `#584/policy-audit.2026-09-04T04-05.md` line 123 a sentence disclosing that the applied format run deviated from the `format .` invocation listed in the CLAUDE.md approved-command list, and cross-referencing the section 8 gap entry that P5-T7 adds. Label the Appendix B "Toolchain Commands Reference" entry at line 421 so a reader cannot mistake it for a transcript: it is the CLAUDE.md reference command, not a record of what ran. Acceptance: the row-3.1 line contains the token `see section 8`; the region containing line 421 contains the token `reference commands, not a transcript of what ran`; and a search of the file for the token `csharpier format .` returns exactly one line, which is the labelled Appendix B entry. + +- [ ] [P5-T7] Add the section 8 gap entry (S3-2). `## 8. Gaps and Exceptions` begins at `#584/policy-audit.2026-09-04T04-05.md` line 244 and its first entry `### B1` is at line 246. Insert a new gap entry in that section recording that the applied format step ran CSharpier over six explicit paths rather than over `.`, citing the rationale recorded in `#584/plan.2026-09-02T09-02.md` at lines 1068-1084 as re-derived in `evidence/baseline/p0-t10-584-plan-rederivation.md`, and recording that the whole-tree `dotnet tool run csharpier check .` run captured in `#584/evidence/qa-gates/p4-t2-format-check.md` is the substantively equivalent mitigation because it verified the entire repository read-only. Do not quote the plan line numbers unless the P0-T10 artifact records them; AC12 forbids carrying an unverified line reference into an artifact. The gap entry must not contain the literal `csharpier format .`. Refer to the whole-tree invocation as the `format .` form or as the CLAUDE.md approved-command form instead. P5-T6 asserts that literal occurs exactly once in this file, on the labelled Appendix B line 421, and P8-T16 re-asserts the same condition after Phase 7. Acceptance: the file contains a new `###` heading inside section 8 whose body contains the token `1068-1084` and the token `p4-t2-format-check.md`; `evidence/baseline/p0-t10-584-plan-rederivation.md` exists and quotes the content at those plan lines; and a search of the `#584` policy-audit artifact for the token `csharpier format .` still returns exactly one line after this task's insertion. + +- [ ] [P5-T8] Correct the evidence count (S3-3). At `#584/policy-audit.2026-09-04T04-05.md` line 68, replace `All 34 evidence artifacts` with `All 38 evidence artifacts`. The figure 38 is corroborated by two independent enumerations recorded in the research record and matches the `git ls-tree` count asserted in `issue.md`. Acceptance: a search of `#584/policy-audit.2026-09-04T04-05.md` for the token `All 34 evidence artifacts` returns zero lines; a search for the token `All 38 evidence artifacts` returns exactly one line. + +- [ ] [P5-T9] Insert the S3-4 naming note. In `#584/evidence/issue-updates/issue-584.2026-09-02T09-02.md`, insert a blockquote note immediately after line 3. The note records that the filename carries the plan's timestamp `2026-09-02T09-02` while the `Timestamp:` field records the posting instant `2026-09-03T22-24`, that the file is committed evidence and is deliberately neither renamed nor re-stamped, and that a future update to issue #584 must use its own posting timestamp in the filename so the two artifacts sort correctly and cannot collide. Do not rename the file. Do not alter the existing `Timestamp:` value on line 3, the `PostedAs: comment` value on line 5, or the comment URL on line 7. Acceptance: a search of this file for the token `Timestamp: 2026-09-03T22-24` returns exactly one line and it is still line 3; a search for the token `PostedAs: comment` returns exactly one line; a search for the token `deliberately neither renamed nor re-stamped` returns exactly one line; and `git add -N -- "docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/evidence/issue-updates/"` followed by `git diff --name-status pre-782-base -- "docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/evidence/issue-updates/"` shows exactly one path with status `M`, and `git status --porcelain --untracked-files=all -- "docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/evidence/issue-updates/"` shows that same one path and no added or deleted path, proving a modification and not a rename. The worktree-form diff is required rather than the two-ref form, because Phase 5 is not committed until P5-T15 and a `pre-782-base..HEAD` comparison would report nothing at this point. + +- [ ] [P5-T10] Normalize the eleven `EXIT_CODE:` fields whose value is empty with a following bullet list (S3-5, SD3). The eleven files, all under `#584/evidence/`, are `qa-gates/p4-t6-quickfiler-tests.md` line 16, `qa-gates/p2-t2-nullforgiving-removed.md` line 11, `qa-gates/p2-t4-emailmovemonitor-reflection-target.md` line 18, `qa-gates/p1-t5-donotparallelize.md` line 11, `qa-gates/p4-t1-format.md` line 15, `qa-gates/p3-t5-no-timing-tokens.md` line 12, `other/p3-t4-progresstrackerasync-unmodified.md` line 13, `other/p5-t10-footprint.md` line 11, `baseline/p0-t13-parallel-bucket-census.md` line 13, `baseline/p0-t14-reflective-dispatcher-census.md` line 12, and `baseline/p0-t5-toolchain-resolution.md` line 30. In each, move the per-command breakdown to a line below the field and put a single integer on the `EXIT_CODE:` line itself. For `p3-t5-no-timing-tokens.md` the true exit code is 1, which is the expected outcome for a no-match grep gate, so write `EXIT_CODE: 1` and add `ExpectedExitCode: 1` on the following line so the collector normalizes the row to pass; do not invent a `0`. For the other ten, the recorded per-command values are all `0`, so the single integer is `0`. Acceptance: for each of the eleven files, a search for `^EXIT_CODE: -?[0-9]+$` returns exactly one line; and a search of `qa-gates/p3-t5-no-timing-tokens.md` for `^ExpectedExitCode: 1$` returns exactly one line. + +- [ ] [P5-T11] Normalize the four remaining deviating `EXIT_CODE:` fields (S3-5, SD3). The four files, all under `#584/evidence/baseline/`, are `p0-t2-uithread-rederivation.md` line 11 (`EXIT_CODE: 0 (both commands)`), `p0-t3-progresstrackerasync-rederivation.md` line 12 (`EXIT_CODE: 0 (all three commands)`), `p0-t4-test-rederivation.md` line 13 (`EXIT_CODE: 0 (all four commands)`), and `p0-t6-mcp-probe.md` line 12 (`EXIT_CODE: non-zero (tool invocation error; no exit code is returned by the MCP transport)`). For the first three, move the parenthetical to a prose line below the field and leave `EXIT_CODE: 0`. For `p0-t6-mcp-probe.md` no process ran, so write a single integer and record on a line below it that the MCP transport returned no exit code and that the integer is a normalization rather than an observed process exit status; add `ExpectedExitCode:` with the same integer so the collector's normalization matches the recorded reality. Acceptance: for each of the four files, a search for `^EXIT_CODE: -?[0-9]+$` returns exactly one line; a search of `p0-t6-mcp-probe.md` for the token `no exit code is returned by the MCP transport` returns exactly one line and that line does not begin with `EXIT_CODE:`; and a search of the same file for `^ExpectedExitCode: -?[0-9]+$` returns exactly one line. + +- [ ] [P5-T12] Replace the six evaluative spans that `.claude/rules/tonality.md` prohibits (S3-8). The six locations are: `#584/feature-audit.2026-09-04T04-05.md` line 117 (`is honest and correct`) and line 119 (`was the right call`); `#584/code-review.2026-09-04T04-05.md` line 22 (`stronger than typical`) and line 191 (`Exemplary`); `#584/policy-audit.2026-09-04T04-05.md` line 111 (`This is a model instance of the rule.`); and `#584/evidence/qa-gates/p2-t3-file-size.md` line 42 (`comfortably inside`). Replace each with neutral, evidence-first wording that states the same fact without the evaluative intensifier — for example `is accurate`, `keeps the criterion binding`, `are recorded here because they bear on the verdict`, `Satisfied`, `states the reason rather than restating the code, which is what the rule requires`, and `which equals the baseline and is therefore within the baseline-plus-one tolerance`. Do not edit `#584/policy-audit.2026-09-04T04-05.md` line 115; P5-T4 owns that line and removes its `provable assertion-level` intensifier in the same phase. All six line numbers above are pre-edit numbers measured against the current tree; P5-T4 edits spans above some of them in the same two files, so locate each of the six by its quoted token rather than by line number. Each of the six tokens occurs exactly once across the whole `#584` folder, so token location is unambiguous. Acceptance: a search across the four audit artifacts and `p2-t3-file-size.md` for each of the tokens `honest and correct`, `was the right call`, `stronger than typical`, `Exemplary`, `model instance of the rule`, and `comfortably inside` returns zero lines in every case. The plan text quotes each of those six tokens verbatim here so the search literals are exonerated as text the task removes rather than text absent from the tree. + +- [ ] [P5-T13] Record the S3-9 disposition (SD9). At `#584/code-review.2026-09-04T04-05.md` line 85, whose text is `**Recommendation:** promote item 1 to a GitHub issue before merge.`, and at the `### F5` finding beginning at `#584/policy-audit.2026-09-04T04-05.md` line 323, append a disposition note recording three facts: that #584 finding F5 asks for synchronization around the existing unsynchronized reflective mutation of `UiThread._dispatcher`, which is discharged by C12 and C13 in issue #782 — the single shared `UiThreadDispatcherScope` install scope that all four `UtilitiesCS.Test` reflection sites migrate to — and not by C26, which adds a new test and changes no existing mutation; that C26 is adjacent coverage rather than the discharging item; and that the follow-up was verifiably never promoted, with no potential entry and no active feature folder covering it and both recommendations remaining open at the time of the #782 review. Acceptance: searches of both files for the token `discharged by C12 and C13` each return at least one line; searches of both files for the token `not by C26` each return at least one line; and searches of both files for the token `never promoted` each return at least one line. + +- [ ] [P5-T14] Gate the Phase 5 corrections. Run three checks. First, search `#584/evidence` for lines matching `^EXIT_CODE:` and assert every returned line also matches `^EXIT_CODE: -?[0-9]+$`. Second, search the four #584 audit artifacts plus `#584/evidence/qa-gates/p2-t3-file-size.md` for each of the six evaluative tokens listed in P5-T12 and for the `provable assertion-level` token removed by P5-T4, and assert zero hits in total across all seven. Third, run `git add -N -- docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584` followed by `git diff --name-only pre-782-base -- docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584` and `git status --porcelain --untracked-files=all -- docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584`. The `git add -N` and the porcelain span are the companions required alongside the name-listing diff, which enumerates tracked changes only. Write `evidence/qa-gates/p5-t14-584-corrections.md` with `Timestamp:`, `Command:` carrying all commands, `EXIT_CODE:` carrying a single integer, and `Output Summary:` carrying the three results in full. Acceptance: the first check returns 37 lines and all 37 match the single-signed-integer form; the second check returns zero hits; and the third check lists exactly 23 paths — the four #584 documents `spec.md`, `policy-audit.2026-09-04T04-05.md`, `feature-audit.2026-09-04T04-05.md`, and `code-review.2026-09-04T04-05.md`; the four non-S3-5 evidence files `evidence/regression-testing/p1-t4-expect-fail.md`, `evidence/qa-gates/p3-t1-analyzer-build.md`, `evidence/qa-gates/p2-t3-file-size.md`, and `evidence/issue-updates/issue-584.2026-09-02T09-02.md`; and the fifteen S3-5 files enumerated in P5-T10 and P5-T11 — with no path outside that set and no path listed as added or deleted. + +- [ ] [P5-T15] Commit Phase 5 and verify commit hygiene. Stage only the 23 #584 paths and the Phase 5 evidence artifact, using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and findings S3-1 through S3-9. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; `git status --porcelain --untracked-files=all -- docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584` returns zero lines; and `git diff --name-only pre-782-base..HEAD -- docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584` returns exactly 23 lines. + +### Phase 6 — Delivery Artifacts + +The code-review artifact filename chosen by P6-T1 and the coverage-summary filename chosen by P7-T6 +are each recorded on their own plan line at the moment they are written. Every later task that cites +them resolves the citation by `Get-ChildItem` over `evidence/other/code-review.*.md` and +`evidence/qa-gates/coverage-summary.*.md` respectively, and its acceptance additionally requires that +exactly one file match each pattern. + +- [ ] [P6-T1] Write this delivery's code-review artifact at `evidence/other/code-review..md`. It must carry `Timestamp:`, `Command:`, `EXIT_CODE: 0`, `Output Summary:`, and a disposition row for every finding identifier in the specification's traceability table plus the no-action set: C01 through C26, S2-1, S3-1 through S3-9, S4-1, and S4-2. Each row names the identifier, the file that changed or the recorded reason it did not, and the commit that carried it. The artifact must additionally record, each as its own explicitly labelled entry: (a) that no unit test covers the C03 catch branch, because `Initialize()` shows a WinForms window and cannot be forced to throw from a test without a new production seam, which is out of scope; (b) that the `WpfDispatcherYield` message's tail "before yielding folder tree work" is intentionally gone under SD5, that this is an accepted and reviewed change rather than a regression, and that it is pinned by the `WithMessage` assertion added by P4-T3; (c) the residual naming inaccuracy of `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` and the SD4 reason the name is retained; (d) the SD10 divergence, that this delivery adopts 49 live reads across 25 production files with the derivation cited while the PR #778 review body states 26 files, and that the review body publishes no member set so the source of the extra file cannot be established; (e) the SD9 attribution of #584 finding F5 to C12 and C13 rather than C26, and that F5 was never promoted; (f) the SD14 supersession of the `spec.md` Constraint 8 clause for the `ForceDispatcherNull` docstring at `IdleAsyncQueue_Tests.cs` lines 150-164, with the reason; (g) that the `spec.md` Constraint 8 clause naming `IdleAsyncQueue_Tests.cs` lines 155-160 as deliberately left is superseded by SD14, because those lines are the `Purpose:` body of the `` block at lines 150-164 that P3-T7 rewrites in full, and that the supersession is a decision rather than an omission; and (h) the SD7 justification for adding `[DoNotParallelize]` to `IdleActionQueue_Tests`, quoting the P0-T11 census finding that the two sibling classes sharing `ApplicationIdleTimer` global state already carry it and this one did not; and (i) the SD17 deviation, that `/EnableCodeCoverage` is not passed, the reason it is not, and that coverage is collected by `dotnet-coverage collect` with the derived configuration in both P0-T7 and P7-T5 so the baseline and final figures are produced by one method. Record the chosen filename on this task's line in this plan at the moment it is written. Acceptance: exactly one file matches `evidence/other/code-review.*.md`; searches of it for each of the tokens `C03`, `SD4`, `SD5`, `SD7`, `SD9`, `SD10`, `SD14`, and `SD17` each return at least one line; a search for the token `S4-1` returns at least one line and a search for the token `S4-2` returns at least one line; and the disposition table contains a row for each of the 26 `C` identifiers, verified by asserting that a search for `^| C` returns exactly 26 lines. + +- [ ] [P6-T2] Write the upstream follow-up record at `evidence/other/upstream-followups-drm-copilot..md`, carrying `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:`. It records two items as follow-ups for the drm-copilot repository, neither fixed here: finding S4-1, the stale notes under `.claude/agent-memory/task-researcher/` that describe `UiThread.Dispatcher` as permanently null in tests and as producing `NullReferenceException`; and the S3-1 request to define `Timestamp:` semantics in the `evidence-and-timestamp-conventions` skill, which specifies only `Timestamp: ` and defines no semantics for which instant it denotes. The artifact states that both live under `.claude/`, which is overwritten by push-down from drm-copilot, so any edit made in this repository is silently lost, and that this delivery therefore modifies nothing under `.claude/`. Record the chosen filename on this task's line in this plan at the moment it is written. Acceptance: exactly one file matches `evidence/other/upstream-followups-drm-copilot.*.md`; searches of it for the tokens `S4-1`, `evidence-and-timestamp-conventions`, and `.claude/agent-memory/task-researcher/` each return at least one line; and a search for the token `drm-copilot` returns at least two lines. The bare token `Timestamp:` is deliberately not asserted: the evidence schema mandates a `Timestamp:` field on this artifact, so a search for it returns at least one line by construction and could not fail. + +- [ ] [P6-T3] Gate the `.claude/` non-modification requirement of AC8 and AC-U2. Run `git diff --stat pre-782-base..HEAD -- .claude` and `git status --porcelain --untracked-files=all -- .claude`. Write `evidence/qa-gates/p6-t3-dotclaude-untouched.md` with `Timestamp:`, `Command:` carrying both command lines, `EXIT_CODE: 0`, and `Output Summary:` carrying both outputs verbatim. Acceptance: `git diff --stat pre-782-base..HEAD -- .claude` produces zero lines of output, and `git status --porcelain --untracked-files=all -- .claude` produces zero lines of output. The porcelain span is required alongside the diff because `.claude/agent-memory/` is a tracked directory in this repository and an untracked addition there would be invisible to the diff alone. The executor must write no agent memory under `.claude/agent-memory/` for the duration of this plan. That directory is tracked in this repository, so a memory write made during execution is indistinguishable from a policy-file edit to this gate and fails it. Any memory the executor wishes to persist is recorded after the final commit of this plan, outside its scope. + +- [ ] [P6-T4] Commit Phase 6 and verify commit hygiene. Stage only the three Phase 6 artifacts under `evidence/other/` and `evidence/qa-gates/`, using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and the delivery code-review and upstream follow-up records. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; and `git ls-files --error-unmatch` succeeds for each of the three artifacts. + +### Phase 7 — Final Toolchain Pass + +Run the five steps in this exact order. **If any step fails, or if any step changes a tracked file, +restart the loop from P7-T1.** `EXIT_CODE: SKIPPED` is not a valid outcome for any task in this +phase. + +- [ ] [P7-T1] Format. Run the `DOTNET_ROOT` / `PATH` preamble, then run `Remove-Item -Recurse -Force TestResults -ErrorAction SilentlyContinue` for the reason stated in P7-T2 — CSharpier 1.2.6 processes `*.xml` by extension and `.csharpierignore` does not cover the `Sequence.xml` that `/Blame` writes, so a left-over results tree is rewritten by this write-mode run — then capture `git status --porcelain --untracked-files=all` into a before-image, run `dotnet tool run csharpier format .`, then capture `git status --porcelain --untracked-files=all` into an after-image. Write `evidence/qa-gates/p7-t1-format.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting the formatter's printed `Formatted files in ms.` line verbatim, the before-image, and the after-image. The exit code alone cannot distinguish a clean run from a repairing one, and CSharpier's `Formatted files` figure is its processed-file count rather than its rewritten-file count, so the before-and-after tree comparison is the observation that decides this gate. Acceptance: `EXIT_CODE: 0`; the artifact records a `Formatted ` line; and the before-image and the after-image are byte-identical. If they differ, the artifact records the differing paths, the changed files are committed, and the loop restarts from this task. + +- [ ] [P7-T2] Verify formatting read-only. First run `Remove-Item -Recurse -Force TestResults -ErrorAction SilentlyContinue` again. The removal is required and is safe: `/Blame` writes a `Sequence.xml` file into the results directory, CSharpier 1.2.6 processes `*.xml` by extension, and `.csharpierignore` covers `*.trx` and `*.cobertura.xml` but not `Sequence.xml`, so a left-over results tree inflates the checked-file count and makes the count assertion below unfalsifiable. `TestResults/` matches the `[Tt]est[Rr]esult*/` entry in `.gitignore`, so nothing tracked is removed, and every fact this plan needs from a TRX is already extracted into an evidence artifact. The operative removal is the one P7-T1 performs before the write-mode format run, because a results tree left in place would be rewritten rather than merely counted; this second removal is an idempotent guard that keeps the count assertion sound when the loop restarts at P7-T1 after P7-T5 has repopulated the tree. `-ErrorAction SilentlyContinue` makes a removal of an already-absent directory exit without error, so running it twice in one pass is a no-op rather than a failure. Then run `dotnet tool run csharpier check .`. Write `evidence/qa-gates/p7-t2-format-check.md` with `Timestamp:`, `Command:` carrying both command lines, `EXIT_CODE:`, and `Output Summary:` quoting the printed `Checked files` line verbatim alongside the baseline value recorded in `evidence/baseline/p0-t3-csharpier-check.md`. Acceptance: `EXIT_CODE: 0`, and the recorded count equals the baseline count plus exactly 2, which for the tabled baseline of 1580 is `Checked 1582 files`. The plus-two is the two files this delivery creates, `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` and `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`. Any other difference means a file was added or removed outside the Write Set and must be reconciled before the task is marked complete. Note that `.csproj`, `.props`, and `.targets` are kept out of the check by `.csharpierignore` rather than by any inherent CSharpier behaviour, and that CSharpier 1.2.6 does process `*.xml` and `packages.config`, so this count also proves that no project file was reformatted. + +- [ ] [P7-T3] Analyzer build. Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true`. Use `/t:Rebuild`, not `/t:Build`: MSBuild's up-to-date check does not invalidate on a command-line `/p:` change, so a warm `/t:Build` returns exit 0 with `CoreCompile` skipped and runs no analyzers. Write `evidence/qa-gates/p7-t3-analyzer-build.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting the `Warning(s)` line, the `Error(s)` line, and the number of distinct project build-output lines. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`, and a project build-output line count equal to the value recorded in `evidence/baseline/p0-t4-analyzer-build.md`, which is 16 unless that artifact carries a `BASELINE_PROJECT_COUNT:` line, in which case that line supplies the expected value. + +- [ ] [P7-T4] Nullable build. Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true /v:n '/flp:LogFile=coverage\782-p7-nullable.log;Verbosity=normal'`. The `/flp:` switch is written in single quotes because PowerShell would otherwise truncate it at the first semicolon and no log file would be produced. Do not add `/p:Nullable=enable`: no project in this repository carries a `` element and there is no `Directory.Build.props`, so the property is a solution-wide opt-in that conscripts every file that has never adopted the pragma, and CI omits it deliberately. Write `evidence/qa-gates/p7-t4-nullable-build.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` quoting the `Warning(s)` line, the `Error(s)` line, and the number of log lines containing the token `CoreCompile`. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`, and a `CoreCompile` execution count equal to the value recorded in `evidence/baseline/p0-t5-nullable-build.md`, which is 51 unless that artifact carries a `BASELINE_CORECOMPILE_COUNT:` line, in which case that line supplies the expected value. + +- [ ] [P7-T5] Test with coverage. Build the derived coverage configuration exactly as in P0-T7, then run `dotnet-coverage collect --output coverage\782-p7-final.cobertura.xml --output-format cobertura --settings coverage\782-effective-coverage.config -- $vstest /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /Logger:trx /ResultsDirectory:TestResults\782-p7 '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None' /TestCaseFilter:""`, with the `/Blame:` switch written in single quotes so PowerShell does not truncate it at the first semicolon. Do not pass `/EnableCodeCoverage`; `dotnet-coverage` performs the instrumentation. Write `evidence/qa-gates/p7-t5-tests-coverage.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:` carrying the test run's `Total tests:`, `Passed:`, `Failed:`, and `Skipped:` values stated as locally-filtered nine-assembly figures rather than CI figures, and, as explicit numerals, the first-party `lines-covered`, `lines-valid`, line percentage, `branches-covered`, `branches-valid`, and branch percentage computed over the nine-name allowlist, plus the root all-modules line and branch percentages. The `Output Summary:` must additionally record the outcome of each of these five fully-qualified tests read from the TRX, so later tasks can cite this artifact rather than a results tree that P8-T20 deletes: `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`, `Dispatcher_WhenBackingFieldIsPopulated_ReturnsThatSameInstance`, `YieldAsync_WithoutDispatcher_RemainsStrict`, `YieldAsync_ProductionFallbackWithoutDispatcher_ThrowsNamingInit`, and `InitializeAsync_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`. Acceptance: `EXIT_CODE: 0`; `Failed: 0`; `Total tests:` is at least the baseline total recorded in `evidence/baseline/p0-t6-vstest.md` plus three, which is 6995 for the tabled baseline of 6992; all six first-party numerals plus both root percentages are present as digits rather than as placeholders; and all five named tests are recorded with outcome `Passed`. + +- [ ] [P7-T6] Commit the package-level coverage summary. Convert the first-party per-package figures from `coverage\782-p7-final.cobertura.xml` into a compact package-level JaCoCo summary and write it to `evidence/qa-gates/coverage-summary..md`, carrying `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:`. The summary carries one row per first-party package with `` and `` values derived by aggregating that package's ``/`` `hits` and `condition-coverage` attributes, plus a total row. `artifacts/csharp/coverage.xml` is deliberately not produced (SD1): the repository pipeline emits Cobertura while the feature-review coverage hook parses JaCoCo, so that path requires a throwaway conversion, and the hook applies a fixed repository-wide line floor that would force a FAIL verdict for a shortfall that pre-exists on `origin/main`. Record the chosen filename on this task's line in this plan at the moment it is written. Acceptance: exactly one file matches `evidence/qa-gates/coverage-summary.*.md`; it carries a row for each of the nine first-party package names; each row's LINE `missed` plus `covered` equals that package's Cobertura `lines-valid`; and the total row's `covered` equals the first-party `lines-covered` figure recorded in P7-T5. + +- [ ] [P7-T7] Compute and gate the changed-line coverage delta (AC9, AC-U5). Derive the changed production line set mechanically: run `git diff pre-782-base..HEAD -- UtilitiesCS/Threading/UiThread.cs UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs UtilitiesCS/Threading/ProgressTracker.cs UtilitiesCS/Threading/ProgressTrackerAsync.cs TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` and take every added line, mapping it to its post-change line number from the hunk headers. For each such line number, look it up as a `` element for that file in `coverage\782-p7-final.cobertura.xml`; a line absent from the document is not executable and is excluded from both numerator and denominator. Changed-line coverage is covered over covered-plus-uncovered. Write `evidence/qa-gates/p7-t7-changed-line-coverage.md` with `Timestamp:`, `Command:` carrying the diff command and the lookup method, `EXIT_CODE: 0`, and `Output Summary:` carrying the full derivation: the changed line numbers per file, the executable subset, the covered count, the uncovered count, the resulting percentage, and an explicit enumeration by file and line number of every uncovered changed line. Also record the first-party `lines-valid` from `evidence/baseline/p0-t7-coverage.md` beside the P7-T5 figure and state whether the two are within 1% of each other. Acceptance: three conditions, all of which must hold. First, every uncovered changed line enumerated in the artifact lies inside the `try`/`catch` construct that P1-T3 added around the `Initialize()` call in `UiThread.Init()` in `UtilitiesCS/Threading/UiThread.cs`; any uncovered changed line outside that construct fails this task, because AC2 records the C03 branch as the single knowingly untested addition and records the reason. The `Initialize()` call itself is expected to be covered, because `QuickFiler.Test/Controllers/QfcHomeControllerRunAsyncTests.cs` calls `UiThread.Init(false)` at line 329 in `Worker_RunWorkerCompleted_HandlesCompletionCorrectly`, and the artifact records that fact. The construct is named rather than the `catch` block alone because P1-T3 re-indents the existing `Initialize();` call and adds the `try` line and the block-closing braces, none of which lie inside the `catch`. Second, if the two `lines-valid` totals are within 1% of each other, the post-change first-party line percentage is at least the baseline first-party line percentage minus 0.50 percentage points and the post-change first-party branch percentage is at least the baseline branch percentage minus 0.50 percentage points; if the two `lines-valid` totals differ by more than 1%, the artifact records `COVERAGE COMPARISON: NOT COMPARABLE` with both `lines-valid` figures and the aggregate comparison is not asserted, the changed-line enumeration carrying the verdict alone. Third, `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` contributes zero executable changed lines, because `TaskMaster/Ribbon/RibbonViewer.cs` declares the partial type `[ExcludeFromCodeCoverage]`; the artifact must record that fact rather than reporting a spurious zero-coverage row for it. + +- [ ] [P7-T8] Record loop closure. Write `evidence/qa-gates/p7-t8-loop-closure.md` with `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:` listing every Phase 7 pass in chronological order, each pass naming its five step artifacts and its outcome, including any pass that failed or that changed a file and therefore forced a restart from P7-T1. Acceptance: the artifact records at least one pass; the final recorded pass shows all five steps green with no tracked-file rewrite after P7-T1; and the before-image and after-image recorded in that pass's `p7-t1-format.md` are byte-identical. + +- [ ] [P7-T9] Commit Phase 7 and verify commit hygiene. Stage only the Phase 7 evidence artifacts and any file the formatter rewrote inside the Write Set, using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and the final toolchain pass. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; and `git status --porcelain --untracked-files=all -- UtilitiesCS TaskMaster UtilitiesCS.Test QuickFiler.Test docs/features/active` returns no line whose path is outside the set `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/plan.2026-09-05T15-47.md`, `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/spec.md`, `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md`. Entries for those three paths are expected and are not a failure: the executor records its own progress in this plan file, so the file is modified by the act of checking off the task that runs this gate, and `spec.md` and `user-story.md` carry acceptance-criteria state that is not committed until P8-T19. `evidence/baseline/p0-t2-base-ref.md` records which of the three were already modified at `pre-782-base`; any of the three that the baseline does not list must be reconciled before this task is marked complete. + +### Phase 8 — Acceptance Criteria Check-off and Closure + +Every task in this phase checks off exactly one acceptance criterion in exactly one document, and +each names the evidence that justifies it. No task checks off more than one criterion. The documents +edited here are Markdown, which is outside CSharpier's target set and outside every MSBuild input, +so these edits do not invalidate the Phase 7 clean pass; P8-T20 re-verifies that. + +The acceptance-criteria status summary is a single artifact whose filename is fixed at +`evidence/other/ac-status-summary..md`, where the timestamp is the one chosen by +P8-T8 and recorded on the P8-T8 line of this plan. P8-T13 and P8-T18 append to that same file and +create no second file. + +- [ ] [P8-T1] Check off AC1 in `spec.md`. Change `- [ ] AC1:` to `- [x] AC1:`, leaving the criterion text unchanged. Evidence cited in the AC status summary: the branch diff for each named file, `evidence/qa-gates/p2-t4-file-size.md`, `evidence/qa-gates/p2-t5-split-test-names.md`, `evidence/qa-gates/p5-t14-584-corrections.md`, and `evidence/qa-gates/p7-t5-tests-coverage.md`. Acceptance: a search of `spec.md` for `^- \[x\] AC1:` returns exactly one line; every artifact named above exists; and `git diff --name-only pre-782-base..HEAD` lists all eleven paths named by AC1's clauses: `UtilitiesCS/Threading/UiThread.cs`, `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`, `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, `UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs`, `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs`, `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, `UtilitiesCS.Test/UtilitiesCS.Test.csproj`, `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs`, `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/policy-audit.2026-09-04T04-05.md`, and `docs/features/active/uithread-dispatcher-null-race-progresstrackerasync-584/feature-audit.2026-09-04T04-05.md`. AC1's seven clauses name eleven distinct files, so the count is eleven and not seven. Every one of these paths is committed before Phase 8 runs, so the two-ref name-listing diff does report them. + +- [ ] [P8-T2] Check off AC2 in `spec.md`. Change `- [ ] AC2:` to `- [x] AC2:`. Acceptance: a search of `spec.md` for `^- \[x\] AC2:` returns exactly one line; exactly one file matches `evidence/other/code-review.*.md`, resolved by `Get-ChildItem` over that pattern, and it contains a disposition row for each of C03, C05, C06, C08, C09, C11, C12, C13, C14, C15, C21, C25, C26, and S2-1; and that artifact records why no unit test covers the C03 catch branch. + +- [ ] [P8-T3] Check off AC3 in `spec.md`. Change `- [ ] AC3:` to `- [x] AC3:`. Acceptance: a search of `spec.md` for `^- \[x\] AC3:` returns exactly one line; and `evidence/qa-gates/p5-t14-584-corrections.md` records all three of its checks as passing — 37 conforming `EXIT_CODE:` lines, zero evaluative-token hits, and exactly the 23 expected #584 paths. + +- [ ] [P8-T4] Check off AC4 in `spec.md`. Change `- [ ] AC4:` to `- [x] AC4:`. Acceptance: a search of `spec.md` for `^- \[x\] AC4:` returns exactly one line; a search of `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` for the token `dispatcher != null` returns zero lines; searches of `UtilitiesCS/Threading/ProgressTracker.cs` and `UtilitiesCS/Threading/ProgressTrackerAsync.cs` for the token `UiThread.Dispatcher` each return exactly one line; and `git diff pre-782-base..HEAD -- TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` contains no hunk touching a line beginning with ` ///`. + +- [ ] [P8-T5] Check off AC5 in `spec.md`. Change `- [ ] AC5:` to `- [x] AC5:`. Acceptance: a search of `spec.md` for `^- \[x\] AC5:` returns exactly one line; `evidence/qa-gates/p3-t10-reflection-sites.md` records exactly two `"_dispatcher"` hits; a search of `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` for the token `FieldInfo` returns zero lines; and `evidence/qa-gates/p7-t5-tests-coverage.md` records `Dispatcher_WhenBackingFieldIsPopulated_ReturnsThatSameInstance` with outcome `Passed`, which is the round-trip restore test. + +- [ ] [P8-T6] Check off AC6 in `spec.md`. Change `- [ ] AC6:` to `- [x] AC6:`. Acceptance: a search of `spec.md` for `^- \[x\] AC6:` returns exactly one line; `evidence/qa-gates/p4-t10-file-size.md` records both `ProgressTracker` test files as strictly under 500 lines; searches of `UtilitiesCS.Test/UtilitiesCS.Test.csproj` for the tokens `Threading\ProgressTracker_Tests.cs` and `Threading\ProgressTracker_ReportAndViewerTests.cs` each return exactly one line; and `evidence/qa-gates/p2-t5-split-test-names.md` records 24 fully-qualified names all beginning `UtilitiesCS.Test.ProgressTracker_Tests.` and all `Passed`. + +- [ ] [P8-T7] Check off AC7 in `spec.md`.

Entries for those three paths are expected and are not a failure: the executor records its own progress in this plan file, so the file is modified by the act of checking off the task that runs this gate, and `spec.md` and `user-story.md` carry acceptance-criteria state that this task's own commit is what clears. Their entries are permitted rather than required here: this gate runs after that commit, so both are expected to be clean, and admitting them keeps the gate from failing on a re-check-off that touches either file. `evidence/baseline/p0-t2-base-ref.md` records which of the three were already modified at `pre-782-base`; any of the three that the baseline does not list must be reconciled before this task is marked complete. -### Phase 3: Verification & Cleanup [0%] -- [ ] Run tests/type checks; fix fallout -- [ ] Update docs/tasks/initiative references -- [ ] Final pass for stray references to old locations +- [ ] [P8-T20] Confirm the Phase 8 Markdown edits did not disturb the Phase 7 clean pass. Run `Remove-Item -Recurse -Force TestResults -ErrorAction SilentlyContinue` for the reason stated in P7-T2, then the `DOTNET_ROOT` / `PATH` preamble, then `dotnet tool run csharpier check .`, then `git status --porcelain --untracked-files=all`. Write `evidence/qa-gates/p8-t20-closure.md` with `Timestamp:`, `Command:` carrying all three command lines, `EXIT_CODE:` carrying a single integer, and `Output Summary:` carrying the printed `Checked files` line and the porcelain output verbatim. Acceptance: `EXIT_CODE: 0`; the recorded count is identical to the count recorded in `evidence/qa-gates/p7-t2-format-check.md`, which for the tabled baseline is `Checked 1582 files`; and the porcelain output, after subtracting every line whose path is `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/plan.2026-09-05T15-47.md`, `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/spec.md`, or `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md`, is byte-identical to the porcelain output recorded in `evidence/baseline/p0-t2-base-ref.md` after subtracting every line whose path is `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/plan.2026-09-05T15-47.md`, `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/spec.md`, or `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md`, so this delivery leaves the worktree in exactly the state it found it apart from its own commits. The subtraction is required because the executor records its progress in this plan file, so the file is modified both at P0-T2 and at this task. The `spec.md` and `user-story.md` subtractions are required in addition to the plan-file subtraction, because both files are already modified in the worktree when P0-T2 records the baseline porcelain and both are committed by P8-T19, so each appears on the baseline side of the comparison and on neither side afterwards. If `evidence/baseline/p0-t2-base-ref.md` records only two of the three, the subtraction still holds: a path absent from both sides of the comparison is unaffected by being subtracted. Comparing against the recorded baseline rather than demanding an empty output is required, because `.claude/agent-memory/` is a tracked directory in this repository that a concurrent session can leave modified; an unconditional empty-porcelain demand would fail for a reason outside this delivery's control. The comparison must additionally confirm that the subtracted output contains no path under the Write Set and no path under the 782 active feature folder. Commit this artifact and this plan file with explicit pathspecs and repeat the comparison afterwards. ## Test Plan -- Unit/Integration: impacted modules and any regression tests for invariants -- CLI/Workflow: end-to-end commands/tasks expected to remain stable -- Tooling: lint/type checks after path updates -- Coverage evidence: list baseline artifact paths, post-change artifact paths, and comparison artifact paths for each in-scope language +- **Unit tests.** MSTest, Moq, and FluentAssertions only, per `CLAUDE.md` § CUT1 and § CUT2.

Every existing test retains + its exact fully-qualified name. +- **Determinism.** No test creates or uses a temporary file; no test uses a sleep, a retry, or a + timing tolerance. Any test that obtains a real `Dispatcher` does so on a dedicated STA thread, + calls `BeginInvokeShutdown` on that dispatcher, and joins the thread in a `finally`, so no + dispatcher outlives the test. The C21 test runs its Act on a dedicated fresh thread that never + touches `Dispatcher.CurrentDispatcher`, because `[DoNotParallelize]` alone does not remove the + pooled-thread coupling. +- **Serialization.** Every class that installs a value into `UiThread._dispatcher` carries + `[DoNotParallelize]`. Phase 4 adds the attribute to `IdleActionQueue_Tests` (SD7) and to + `WpfDispatcherYieldTests`. +- **Assemblies.** All nine test assemblies are run in Phases 0, 4, and 7. Phases 1, 2, and 3 run + scoped subsets as intermediate gates only; those subsets never replace the nine-assembly runs. +- **Coverage evidence.** Baseline: `evidence/baseline/p0-t7-coverage.md`. Post-change: + `evidence/qa-gates/p7-t5-tests-coverage.md` and + `evidence/qa-gates/coverage-summary..md`. Comparison: + `evidence/qa-gates/p7-t7-changed-line-coverage.md`. ## Rollback / Contingency -How to revert or isolate if the refactor breaks downstream consumers (e.g., keep branch snapshot, git move plan). +Each phase commits independently against the `pre-782-base` tag, so any phase can be reverted with +`git revert` without disturbing its predecessors. The two temporary source edits made in P4-T7 are +reverted in P4-T8 with `git checkout HEAD -- ` and the revert is proved by a diff +comparison against the Phase 1 recorded diff, so no fail-before residue can reach a commit. No file +under `.claude/` is written at any point; P6-T3 gates that requirement, and both a diff and a +porcelain span are used because `.claude/agent-memory/` is tracked in this repository. ## Open Questions / Notes -Capture decisions, risks, and follow-ups. +- The promotion of the C09 behavioural follow-up, pull-request authoring, and the CI gate are + orchestrator steps outside this plan. AC8 and AC-U1 carry gated two-branch resolutions that set the + box only when the orchestrator's artefact is already present, and otherwise record an explicit + deferral. +- The `TryAddValuesAsync_UpdatesExistingValue` flake is tracked as issue #780 and is not a regression + of this delivery. Every test task records it explicitly if it occurs. +- The four shell-icon test classes are excluded by `/TestCaseFilter` for environmental reasons that + reproduce against `origin/main`.

The plan now clears preflight with PREFLIGHT: ALL CLEAR and CONVERGENCE: NO FURTHER ROUNDS EXPECTED. The substantive corrections were: the thirteen Phase 0 baseline artifacts were never staged, which made both terminal porcelain gates unpassable; the shared test seam used nullable annotations that raise CS8632 in this repository and would have failed the nullable build; a mandated document edit recorded 2026-09-05 as the PR #778 merge date where the merge commit dates to 2026-09-04; three baseline counts were pinned as hard equalities with no record-and-continue escape; and three tasks justified a TestResults removal on the premise that CSharpier would process its output, which is false because CSharpier 1.2.6 honours .gitignore.

The removal is required and is safe: `/Blame` writes a `Sequence.xml` file into the results directory, CSharpier 1.2.6 processes `*.xml` by extension, and `.csharpierignore` covers `*.trx` and `*.cobertura.xml` but not `Sequence.xml`, so a left-over results tree inflates the checked-file count and makes the count assertion below unfalsifiable. `TestResults/` matches the `[Tt]est[Rr]esult*/` entry in `.gitignore`, so nothing tracked is removed, and every fact this plan needs from a TRX is already extracted into an evidence artifact. The operative removal is the one P7-T1 performs before the write-mode format run, because a results tree left in place would be rewritten rather than merely counted; this second removal is an idempotent guard that keeps the count assertion sound when the loop restarts at P7-T1 after P7-T5 has repopulated the tree. `-ErrorAction SilentlyContinue` makes a removal of an already-absent directory exit without error, so running it twice in one pass is a no-op rather than a failure.

The removal is safe and is defence in depth rather than a load-bearing precondition. `TestResults/` matches the `[Tt]est[Rr]esult*/` entry in `.gitignore`, so nothing tracked is removed; and CSharpier 1.2.6 honours `.gitignore`, so a left-over results tree is not discovered by the whole-tree scan and does not enter the checked-file count. That was measured directly: `dotnet tool run csharpier check packages` reports `Checked 0 files` although `packages/` contains 1593 `*.xml` and `*.config` files and is not a CSharpier built-in exclusion. The same mechanism is what keeps `coverage\782-effective-coverage.config` out of the count — CSharpier does discover plain `*.config` files by directory scan, and `coverage/*` is git-ignored — which is why the plus-two below is exactly two and not three.

align the `UiThread` assertion with the new `Init()` wording - route `WpfDispatcherYield` and `ProgressTracker*` through the shared or already-captured dispatcher and remove dead null checks in ribbon command invalidation - capture Phase 0 baseline evidence and update the #782 plan/spec to record corrected baselines and the documented omission of the C03 latch re-arm Refs: #782 --- .../Ribbon/RibbonViewer.EngineCommands.cs | 4 +- UtilitiesCS.Test/Threading/UiThread_Tests.cs | 2 +- .../Folder/WpfDispatcherYield.cs | 11 +- UtilitiesCS/Threading/ProgressTracker.cs | 2 +- UtilitiesCS/Threading/ProgressTrackerAsync.cs | 2 +- UtilitiesCS/Threading/UiThread.cs | 46 ++++- .../baseline/p0-t10-584-plan-rederivation.md | 62 ++++++ .../p0-t11-idle-serialization-census.md | 57 ++++++ .../baseline/p0-t12-exitcode-census.md | 87 ++++++++ .../baseline/p0-t13-reflection-census.md | 60 ++++++ .../evidence/baseline/p0-t2-base-ref.md | 39 ++++ .../baseline/p0-t3-csharpier-check.md | 28 +++ .../evidence/baseline/p0-t4-analyzer-build.md | 64 ++++++ .../evidence/baseline/p0-t5-nullable-build.md | 60 ++++++ .../evidence/baseline/p0-t6-vstest.md | 73 +++++++ .../evidence/baseline/p0-t7-coverage.md | 125 ++++++++++++ .../evidence/baseline/p0-t8-line-counts.md | 31 +++ .../baseline/p0-t9-584-spec-rederivation.md | 61 ++++++ .../baseline/phase0-instructions-read.md | 38 ++++ .../evidence/qa-gates/p1-t8-phase1-builds.md | 47 +++++ .../plan.2026-09-05T15-47.md | 192 +++++++++++++----- .../spec.md | 10 +- 22 files changed, 1025 insertions(+), 76 deletions(-) create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t10-584-plan-rederivation.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t11-idle-serialization-census.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t12-exitcode-census.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t13-reflection-census.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t2-base-ref.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t3-csharpier-check.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t4-analyzer-build.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t5-nullable-build.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t6-vstest.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t7-coverage.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t8-line-counts.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t9-584-spec-rederivation.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/phase0-instructions-read.md create mode 100644 docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/qa-gates/p1-t8-phase1-builds.md diff --git a/TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs b/TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs index fe428dba3..ceecfdaf4 100644 --- a/TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs +++ b/TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs @@ -69,7 +69,7 @@ internal void InvalidateEngineCommands() } var dispatcher = UiThread.Dispatcher;

Keep the declared type non-nullable `Dispatcher` and keep the private setter; this is not a public signature change. Add the C05 comment immediately above the throw, stating that `Initialize()` constructs and shows a hidden WinForms `SyncContextForm` and must run on the UI thread, so a lazy `Init()` from an arbitrary reader is deliberately avoided even though the sibling `UiSyncContext` and `AutoScaleFactor` accessors do self-heal. Add the C08 XML documentation on the property: a ``, a `` documenting the deliberate non-lazy contract, and an ``. Acceptance: a search of the file for the token `_dispatcher is null` returns zero lines; a search for the token `return _dispatcher;` returns zero lines; a search for the token `= _dispatcher;` returns exactly one line, which is the getter's single capture of the backing field into a local; a search for the token `///` returns at least three lines; and a search for the literal string `"The UI dispatcher has not been captured.` returns exactly one line, which is the constant declaration added by P1-T1. -- [ ] [P1-T2] Rewrite the `UiThread.Dispatcher` getter in `UtilitiesCS/Threading/UiThread.cs` so it reads the backing field exactly once into a local, tests the local, throws `new InvalidOperationException(DispatcherNotInitializedMessage)` when the local is null, and returns that same local otherwise (C02, C06, C09-message, C20).

This is an omission recorded under the omission branch that AC2 already carries — "or its omission is recorded with a stated reason in this delivery's code-review artifact" — and not a silent skip. A previous execution attempt already applied the re-arm to the worktree, so this task is a revert rather than a no-op: remove the `try` and the `catch` that were wrapped around the `Initialize()` call inside `if (_loaded.CheckAndSetFirstCall)`, remove the `_loaded = new ThreadSafeSingleShotGuard();` assignment and the bare `throw;` inside that `catch`, remove the three-line comment above the assignment, and restore the original indentation of the `Initialize();` call, so that the body of the `Init` method is byte-identical to its `pre-782-base` form. Change nothing else in this file: the P1-T1 constant and the P1-T2 getter rewrite stay. -- [ ] [P1-T3] Add the failed-initialization re-arm to `UiThread.Init()` in `UtilitiesCS/Threading/UiThread.cs` (C03). Keep the single-shot latch check at line 36 before `Initialize()` runs, so two concurrent callers cannot both enter `Initialize()`. Wrap the `Initialize()` call in a `try` whose `catch` assigns a fresh `ThreadSafeSingleShotGuard` to the `_loaded` field and then rethrows the original exception unchanged with a bare `throw;`. Add a comment on the catch stating that it exists to re-arm the latch, not to absorb the failure, so the broad catch remains within the General Code Change Policy. Acceptance: a search of the file for the single-line token `_loaded = new ThreadSafeSingleShotGuard()` returns exactly two lines — the field initializer at the declaration and the re-arm inside the catch; and a search for the single-line token `throw;` returns exactly one line. + **Why C03 is dropped, measured rather than inferred.** The single line `_loaded = new ThreadSafeSingleShotGuard();` inside the catch causes `UtilitiesCS.Test.Extensions.DictionaryExtensions_Tests.TryAddValuesAsync_UpdatesExistingValue` to fail reproducibly. The executor bisected it: with that line, `UtilitiesCS.Test` plus `TaskMaster.Test` returns 5179/5180 with that test failing at a 21-second duration; without it, and with nothing else changed, the same pair returns 5180/5180. The branch base returns 6992/6992 over the nine assemblies both before and after the failing runs, so this is delivery-attributable and is not the issue #780 flake this plan anticipates elsewhere. The mechanism is visible in the source. The `UiSyncContext` getter at `UtilitiesCS/Threading/UiThread.cs` lines 128-131 and the `AutoScaleFactor` getter at lines 194-197 both call `Init()` lazily when their backing field is null. `Initialize()` at lines 59-90 constructs a `SyncContextForm` and calls `Show()` on it. Without the re-arm the latch stays set after a first failure and every later `Init()` is a cheap no-op; with the re-arm, every subsequent read of either lazy accessor retries the WinForms construction and throws again, starving the thread pool and defeating the 500 ms `CancelAfter` at `UtilitiesCS/Extensions/DictionaryExtensions.cs` line 177. The file's own documentation already states the collision: the `Dispatcher` XML `` at lines 152-159 and the inline comment at lines 173-176 record that `Initialize()` has UI-thread affinity and that a lazy `Init()` from an arbitrary reader is deliberately avoided for `Dispatcher`. C03's re-arm collides with the two accessors that do still self-heal. The retry semantics C03 asks for are promoted as a separate follow-up entry by the orchestrator; P8-T21 records that promotion's state. -- [ ] [P1-T4] Correct the comment and route the throw through the shared constant in `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` (C20). Replace the false clause at lines 57-59 — which states that `UiThread.Dispatcher` "is null outside a live host" — with text stating that the production fallback provider throws directly from `UiThread.Dispatcher`, so the local `dispatcher is null` guard is unreachable on the production path and covers only injected providers, which are typed `Func` and exist only in tests. Replace the message literal at lines 64-66 with `UiThread.DispatcherNotInitializedMessage`. Acceptance: a search of this file for the token `DispatcherNotInitializedMessage` returns exactly one line; a search of the whole `UtilitiesCS` project directory for the token `before yielding folder tree work` returns zero lines; and a search of this file for the token `is set-once state populated by` returns zero lines. + Record the omission and this evidence in the Phase 6 code-review artifact: P6-T1 entry (a) carries it, including the verbatim single-line token `C03 OMITTED: latch re-arm not implemented`, the bisect figures 5179/5180 and 5180/5180, and the two lazy accessors named above. -- [ ] [P1-T5] Update the single breaking assertion in `UtilitiesCS.Test/Threading/UiThread_Tests.cs`. Change the `WithMessage` argument on line 152 from `"*UiThread.Initialize()*"` to `"*UiThread.Init()*"`. Do **not** rename the enclosing test method `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`; its fully-qualified name is quoted inside a `TestCaseFilter` expression in a committed #584 regression-testing evidence artifact and renaming would make that recorded command resolve to zero tests (SD4).

Every remaining hunk in that diff therefore belongs to P1-T1 and P1-T2. The diff is anchored to the `pre-782-base` ref operand rather than left unanchored, so it does not pass vacuously once Phase 1 is committed. -- [ ] [P1-T6] Apply the C23 lambda-capture change to `UtilitiesCS/Threading/ProgressTracker.cs` and `UtilitiesCS/Threading/ProgressTrackerAsync.cs`. In each file, replace the re-read `UiDispatcher = UiThread.Dispatcher,` inside the `ProgressViewer` object initializer at line 39 with the already-captured local, so the initializer reads `UiDispatcher = UiDispatcher,`.

This entry must open with the verbatim single-line token `C03 OMITTED: latch re-arm not implemented` and must then record, as its own labelled sub-entries: that C03 is discharged through the omission branch AC2 carries rather than by an implementation, so `UtilitiesCS/Threading/UiThread.cs` keeps its `pre-782-base` `Init()` body; the measured regression, that the re-arm made `UtilitiesCS.Test.Extensions.DictionaryExtensions_Tests.TryAddValuesAsync_UpdatesExistingValue` fail reproducibly at a 21-second duration against the 500 ms `CancelAfter` budget at `UtilitiesCS/Extensions/DictionaryExtensions.cs` line 177; the bisect, that `UtilitiesCS.Test` plus `TaskMaster.Test` returns 5179/5180 with the single line `_loaded = new ThreadSafeSingleShotGuard();` present in the catch and 5180/5180 with that one line removed and nothing else changed, while the branch base returns 6992/6992 over the nine assemblies both before and after the failing runs, so the failure is delivery-attributable and is not the issue #780 flake; the mechanism, that the `UiSyncContext` getter at `UtilitiesCS/Threading/UiThread.cs` lines 128-131 and the `AutoScaleFactor` getter at lines 194-197 both call `Init()` lazily, so a re-armed latch makes every later read of either accessor retry the WinForms `SyncContextForm` construction in `Initialize()` and throw again, starving the thread pool; and that the retry semantics C03 asks for are promoted as a separate follow-up entry through the promotion lifecycle by the orchestrator, whose state P8-T21 records. The entry must not claim that a unit test covers the branch and must not claim the branch exists. It must additionally record which parts of `spec.md` SD18 supersedes and which it does not, so a reader comparing the specification against the shipped tree finds the divergence already accounted for: the amendment made to `spec.md` under SD18 is confined to the AC2 C03 clause, so the Behavioral Contract subsection headed `UiThread.Init()`, the C03 cell in the `UtilitiesCS/Threading/UiThread.cs` Write Set row, and the C03 row of the traceability table all still describe the re-arm and are superseded by SD18 as a recorded decision rather than as an oversight. It must also record that `user-story.md` AC-U2 needs no amendment, because it bounds the permitted production behaviour changes from above rather than requiring both of the two it names; (b) that the `WpfDispatcherYield` message's tail "before yielding folder tree work" is intentionally gone under SD5, that this is an accepted and reviewed change rather than a regression, and that it is pinned by the `WithMessage` assertion added by P4-T3; (c) the residual naming inaccuracy of `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` and the SD4 reason the name is retained; (d) the SD10 divergence, that this delivery adopts 49 live reads across 25 production files with the derivation cited while the PR #778 review body states 26 files, and that the review body publishes no member set so the source of the extra file cannot be established; (e) the SD9 attribution of #584 finding F5 to C12 and C13 rather than C26, and that F5 was never promoted; (f) the SD14 supersession of the `spec.md` Constraint 8 clause for the `ForceDispatcherNull` docstring at `IdleAsyncQueue_Tests.cs` lines 150-164, with the reason; (g) that the `spec.md` Constraint 8 clause naming `IdleAsyncQueue_Tests.cs` lines 155-160 as deliberately left is superseded by SD14, because those lines are the `Purpose:` body of the `` block at lines 150-164 that P3-T7 rewrites in full, and that the supersession is a decision rather than an omission; and (h) the SD7 justification for adding `[DoNotParallelize]` to `IdleActionQueue_Tests`, quoting the P0-T11 census finding that the two sibling classes sharing `ApplicationIdleTimer` global state already carry it and this one did not; and (i) the SD17 deviation, that `/EnableCodeCoverage` is not passed, the reason it is not, and that coverage is collected by `dotnet-coverage collect` with the derived configuration in both P0-T7 and P7-T5 so the baseline and final figures are produced by one method.

Also record the first-party `lines-valid` from `evidence/baseline/p0-t7-coverage.md` beside the P7-T5 figure and state whether the two are within 1% of each other. Acceptance: three conditions, all of which must hold. First, every uncovered changed line enumerated in the artifact lies inside the `try`/`catch` construct that P1-T3 added around the `Initialize()` call in `UiThread.Init()` in `UtilitiesCS/Threading/UiThread.cs`; any uncovered changed line outside that construct fails this task, because AC2 records the C03 branch as the single knowingly untested addition and records the reason. The `Initialize()` call itself is expected to be covered, because `QuickFiler.Test/Controllers/QfcHomeControllerRunAsyncTests.cs` calls `UiThread.Init(false)` at line 329 in `Worker_RunWorkerCompleted_HandlesCompletionCorrectly`, and the artifact records that fact. The construct is named rather than the `catch` block alone because P1-T3 re-indents the existing `Initialize();` call and adds the `try` line and the block-closing braces, none of which lie inside the `catch`. Second, if the two `lines-valid` totals are within 1% of each other, the post-change first-party line percentage is at least the baseline first-party line percentage minus 0.50 percentage points and the post-change first-party branch percentage is at least the baseline branch percentage minus 0.50 percentage points; if the two `lines-valid` totals differ by more than 1%, the artifact records `COVERAGE COMPARISON: NOT COMPARABLE` with both `lines-valid` figures and the aggregate comparison is not asserted, the changed-line enumeration carrying the verdict alone. Third, `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` contributes zero executable changed lines, because `TaskMaster/Ribbon/RibbonViewer.cs` declares the partial type `[ExcludeFromCodeCoverage]`; the artifact must record that fact rather than reporting a spurious zero-coverage row for it. +- [ ] [P7-T7] Compute and gate the changed-line coverage delta (AC9, AC-U5).

For each such line number, look it up as a `` element for that file in `coverage\782-p7-final.cobertura.xml`, using the all-descendant `.//line` selection pinned in P0-T7 and P7-T5 (SD22) rather than `classes/class/lines/line`, which yielded 65899 against the baseline's 132967, or `classes/class/methods/method/lines/line`, which yielded 67068. Because that selection reaches a line both at class level and inside its method, one changed line number can match more than one `` element; count each changed line number once and treat it as covered when any matching element for that file carries a `hits` attribute greater than zero. A line number that matches no element is not executable and is excluded from both numerator and denominator. Changed-line coverage is covered over covered-plus-uncovered. Write `evidence/qa-gates/p7-t7-changed-line-coverage.md` with `Timestamp:`, `Command:` carrying the diff command and the lookup method, `EXIT_CODE: 0`, and `Output Summary:` carrying the full derivation: the changed line numbers per file, the executable subset, the covered count, the uncovered count, the resulting percentage, and an explicit enumeration by file and line number of every uncovered changed line. Also record the first-party `lines-valid` from `evidence/baseline/p0-t7-coverage.md` beside the P7-T5 figure and state whether the two are within 1% of each other. Acceptance: three conditions, all of which must hold. First, the artifact enumerates every uncovered changed line by file and line number and that enumeration is empty. **This condition was rewritten by SD18.** Its previous form exempted the uncovered lines of the `try`/`catch` construct that P1-T3 then added around the `Initialize()` call in `UiThread.Init()`; SD18 withdraws that construct, so the plan no longer expects any knowingly-uncovered changed production line and the exemption has nothing left to exempt. Every added executable line in the changed set is expected to be covered: the getter's single field read, its null test, its throw, and its return are exercised by `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` and `Dispatcher_WhenBackingFieldIsPopulated_ReturnsThatSameInstance`; the `WpfDispatcherYield` throw is exercised by `YieldAsync_WithoutDispatcher_RemainsStrict`; and the two `UiDispatcher = UiDispatcher,` initializer lines are exercised by the `ProgressTracker` and `ProgressTrackerAsync` initialization tests. The `internal const string` declaration and the added XML-documentation and comment lines are not executable and are therefore absent from the document and excluded from the enumeration. A non-empty enumeration is a real coverage gap rather than an anticipated one: the task is not complete, the artifact records each uncovered line with its file, its line number, and the reason it is uncovered, and the executor reports before proceeding. Second, if the two `lines-valid` totals are within 1% of each other, the post-change first-party line percentage is at least the baseline first-party line percentage minus 0.50 percentage points and the post-change first-party branch percentage is at least the baseline branch percentage minus 0.50 percentage points; if the two `lines-valid` totals differ by more than 1%, the artifact records `COVERAGE COMPARISON: NOT COMPARABLE` with both `lines-valid` figures and the aggregate comparison is not asserted, the changed-line enumeration carrying the verdict alone. Third, `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` contributes zero executable changed lines, because `TaskMaster/Ribbon/RibbonViewer.cs` declares the partial type `[ExcludeFromCodeCoverage]`; the artifact must record that fact rather than reporting a spurious zero-coverage row for it. - [ ] [P7-T8] Record loop closure.

The comparison must additionally confirm that this task's own subtracted porcelain output — not the recorded baseline side — contains no path under the Write Set and no path under `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/`. Commit this artifact and this plan file with explicit pathspecs and repeat the comparison afterwards. + +- [ ] [P8-T21] Record the state of the C03 follow-up promotion through an explicitly gated two-branch check. This task performs no promotion. The promotion of the C03 follow-up — restoring the retry semantics C03 asked for, by some mechanism that does not re-arm the latch that the two lazy accessors `UiSyncContext` and `AutoScaleFactor` consume — is an orchestrator step performed through the MCP promotion lifecycle outside this plan, exactly as the C09 behavioural follow-up in P8-T8 is. This task records which state that promotion is in, and nothing else. Run `Get-ChildItem -LiteralPath 'docs/features/potential/promoted' -Filter '*.md' | Select-String -Pattern 'latch re-arm|single-shot latch|ThreadSafeSingleShotGuard|retry after a failed Initialize'` and record the full result. Branch A applies when that search returns at least one file **and** that file contains a line matching `^- Issue: #[0-9]+`: in that case write a line beginning with the verbatim token `C03 FOLLOW-UP PROMOTED:` naming that file's path and its issue number. Branch B applies when the search returns zero files, or returns one or more files none of which contains a line matching `^- Issue: #[0-9]+`: in that case write the line `C03 FOLLOW-UP DEFERRED: the UiThread.Init() latch re-arm has not yet been promoted; owner is the orchestrator, which performs promotion outside this plan.` verbatim. Write the chosen branch, the search command, and its full output to `evidence/other/c03-followup-state..md`, carrying `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:`. Record the chosen filename on this task's line in this plan at the moment it is written. A separate artifact is used rather than the acceptance-criteria status summary that P8-T8 and P8-T13 write to, because this task runs after P8-T19 has committed that summary and after P8-T18 has verified its row count, and appending to it here would reopen both. Then stage this artifact and this plan file with explicit pathspecs, never `git add -A`, commit with a message naming issue #782 and the C03 follow-up state record, and repeat the P8-T20 porcelain comparison afterwards, because this task is the terminal task of the plan and the clean-tree state P8-T20 established must be re-established here. Acceptance: the search command was run and its full output is recorded in the artifact; exactly one file matches `evidence/other/c03-followup-state.*.md`, resolved by `Get-ChildItem` over that pattern; exactly one of the two branches was taken and the artifact names which; a search of the artifact for the token `C03 FOLLOW-UP` returns exactly one line, so exactly one of the two branch lines is present and not both; `git ls-files --error-unmatch` exits 0 for that artifact, proving it is committed rather than merely present on disk; and the repeated P8-T20 comparison holds under the same four-path subtraction P8-T20 defines. ## Test Plan @@ -529,12 +604,19 @@ porcelain span are used because `.claude/agent-memory/` is tracked in this repos ## Open Questions / Notes -- The promotion of the C09 behavioural follow-up, pull-request authoring, and the CI gate are - orchestrator steps outside this plan.

The plan's implementation of finding C03, which re-arms the UiThread.Init() single-shot latch so a failed Initialize() can be retried, causes DictionaryExtensions_Tests.TryAddValuesAsync_UpdatesExistingValue to fail reproducibly. The executor bisected it to the single re-arm line: with it, UtilitiesCS.Test plus TaskMaster.Test returns 5179/5180 with that test failing at a 21-second duration; without it, 5180/5180. The branch base passes 6992/6992 both before and after. The UiSyncContext and AutoScaleFactor getters call Init() lazily when their backing field is null, and Initialize() constructs a SyncContextForm and shows it. Without the re-arm the latch stays set after a first failure and later Init() calls are cheap no-ops; with it, every read of either accessor retries the WinForms construction and throws again, starving the thread pool and defeating a 500 ms CancelAfter. C03 is withdrawn under the omission branch AC2 already carries. The retry semantics will be promoted as a separate follow-up entry, in the same way the issue already carved out the C09 behavioral half. Also folds in four execution-time corrections: the CoreCompile gate now asserts a deterministic per-project sub-count instead of an unstable header equality; two baseline figures are corrected to the executor's measurements; the hook-blocked Remove-Item form is replaced; and the coverage line-counting selection is pinned.

The tag is re-anchored to 736c2cf2, the last documentation-only commit before the implementation commit, and verified as an ancestor of HEAD whose source tree is byte-identical to origin/main. The baselines were re-measured at that anchor and the affected Phase 0 tasks are unchecked for re-recording: csharpier now reports 1581 files, the suite reports 6997 passing, and first-party coverage is 112355/132967 line and 26500/33480 branch. The 34-commit main advance touches no file in this delivery's write set. A further preflight round removed five defects. Two were blocking and of the same class: both promotion-state gates searched docs/features/potential/promoted without excluding this delivery's own promoted entry, which carries the tokens they match and an issue line naming #782, so each would have fired its positive branch before any promotion occurred. One of the two would have checked off AC8 on the strength of an unrelated 2026-08-07 WebView2 entry. The third blocking defect was a preamble that still told the executor to create the anchor tag at the branch tip, which P0-T2 now prohibits because it would make every anchored gate compare a tree against itself.

That was measured, not inferred: base source passed 6992/6992 on the nine assemblies three separate times, including a run taken after the failing runs — 6992 being the figure at the superseded base `b95a5252`, retained verbatim as measured rather than restated against the re-anchored baseline of 6997; the Phase 1 tree failed the same test on every one of six runs across three assembly-set configurations; and removing the single line `_loaded = new ThreadSafeSingleShotGuard();` from the catch, changing nothing else, turned 5179/5180 into 5180/5180 on the `UtilitiesCS.Test` plus `TaskMaster.Test` pair. The failing test took 21 seconds against the 500 ms `CancelAfter` budget at `UtilitiesCS/Extensions/DictionaryExtensions.cs` line 177, which is thread-pool blocking rather than a marginal timing miss, and it is not the issue #780 flake this plan's Open Questions section anticipates. SD18 withdraws the re-arm, so the condition is now reachable. Run this task against the reverted tree produced by the rewritten P1-T3 and the re-run P1-T8.

A separate artifact is used rather than the acceptance-criteria status summary that P8-T8 and P8-T13 write to, because this task runs after P8-T19 has committed that summary and after P8-T18 has verified its row count, and appending to it here would reopen both. Then stage this artifact and this plan file with explicit pathspecs, never `git add -A`, commit with a message naming issue #782 and the C03 follow-up state record, and repeat the P8-T20 porcelain comparison afterwards, because this task is the terminal task of the plan and the clean-tree state P8-T20 established must be re-established here. Acceptance: the search command was run and its full output is recorded in the artifact; exactly one file matches `evidence/other/c03-followup-state.*.md`, resolved by `Get-ChildItem` over that pattern; exactly one of the two branches was taken and the artifact names which; the artifact records the excluded filename `2026-09-05-pr-778-post-merge-review-residuals.md`, records that the unfiltered pattern matches it on line 56, and records that Branch B is the state the plan measured at authoring time, so a Branch A result is a real change of state rather than the pre-existing match; a search of the artifact for the token `C03 FOLLOW-UP` returns exactly one line, so exactly one of the two branch lines is present and not both; `git ls-files --error-unmatch` exits 0 for that artifact, proving it is committed rather than merely present on disk; and the repeated P8-T20 comparison holds under the same four-path subtraction P8-T20 defines. ## Test Plan @@ -619,5 +735,16 @@ porcelain span are used because `.claude/agent-memory/` is tracked in this repos removed by the SD18 revert, as P1-T9 records. - The four shell-icon test classes are excluded by `/TestCaseFilter` for environmental reasons that reproduce against `origin/main`.

From 945beb840ccc43c8d4b27c3c3728197f95ea9aa8 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 22:02:15 -0400 Subject: [PATCH 08/28] fix(782): route dispatcher throws through a shared constant and drop dead guards Addresses issue #782 findings C01, C02, C05, C06, C08, C09-message, C20, and C23. Adds the shared UiThread.DispatcherNotInitializedMessage constant, rewrites the Dispatcher getter to read the backing field once, corrects the WpfDispatcherYield comment and message, updates the breaking UiThread_Tests assertion, applies the lambda-capture fix in both ProgressTracker files, and removes the two dead null comparisons in RibbonViewer.EngineCommands.cs. Finding C03 is deliberately absent from that list. SD18 withdraws it after a measured, bisected regression, so this phase changes no line on its account and naming it would misdescribe the commit. The omission is recorded in the Phase 6 code-review artifact. Also carries the Phase 0 baseline evidence, re-recorded under SD23 against the re-anchored pre-782-base at 736c2cf2.

That is the direct +confirmation of SD19's premise. The build runs under `/m`, and the file logger re-emits a +node-prefixed target header each time it switches node context, so the header count depends on how +the parallel nodes interleave rather than on how many times the target ran.

From 587cdf16b97e1881a9dc8e1d1b35e2dd627e44c0 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 22:06:15 -0400 Subject: [PATCH 09/28] refactor(782): split ProgressTracker_Tests and separate its class attributes Addresses issue #782 findings C15 and C16. Moves the P74 Report/child/root-close region out of UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs into a new partial-class file ProgressTracker_ReportAndViewerTests.cs, bringing the 514-line source file to 272 lines and the new file to 260. Splits the combined [TestClass, DoNotParallelize] attribute into two separate attribute lines. The region was extracted mechanically rather than retyped, so no test method name, attribute, or assertion changed. A scoped run of the 24 ProgressTracker_Tests cases confirms all 24 reassemble under their original fully-qualified names and pass.

From d5e192b3a0d8048216e1c000f9becaac8827b448 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 22:32:36 -0400 Subject: [PATCH 10/28] refactor(782): centralize UiThread dispatcher reflection in a shared install scope Phase 3 of issue #782. Replaces five hand-rolled reflective acquisitions of the private static UiThread dispatcher backing field with a single shared install scope, and corrects the documentation that described the pre-#778 mechanism. - C12/C13: UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs now owns the only reflection site in that assembly. IdleAsyncQueue_Tests reimplements its ForceDispatcherNull/RestoreDispatcher helpers over the scope and drops its own DispatcherField() helper. - C10: the populated-branch UiThread_Tests case obtains its sentinel dispatcher from a dedicated STA host that shuts down and joins, instead of calling Dispatcher.CurrentDispatcher on a pooled MTA worker. - C11: the null-branch assertion lambda is expression-bodied. - C18/C25: EmailMoveMonitorTests reads the existing QuickFiler.Test fixture accessor and takes a typed Dispatcher snapshot; the two stale "avoid WindowsBase" clauses are removed. - C19: the three P27-T2 passages now describe the synchronous InvalidOperationException path rather than a NullReferenceException. Repository-wide reflective acquisitions of the backing field fall from six to two, the two being the UtilitiesCS.Test scope and the QuickFiler.Test fixture that a separate assembly must keep.

From 06b6677adffc136e7adb371771e66d6c82b59355 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 22:47:07 -0400 Subject: [PATCH 11/28] test(782): add AC7 regression tests and fix test-hygiene residuals Phase 4 of issue #782. - C14/SD7: IdleActionQueue_Tests gains [DoNotParallelize] and a [TestCleanup] that reuses the existing ResetStaticState() helper and additionally detaches the queue's idle handler, which is rebuilt over the private static method because the registered delegate instance is not nameable from the test. - C21: new WpfDispatcherYieldTests.YieldAsync_ProductionFallbackWithoutDispatcher_ThrowsNamingInit exercises the production fallback provider from a dedicated fresh thread, so the thread-affinitized lookup cannot pre-empt it. The class gains [DoNotParallelize] because it now installs into the process-global static. - C26: two new tests pin the guard on both initialization entry points - ProgressTrackerAsync.InitializeAsync faults its returned task, and ProgressTracker.Initialize throws synchronously, so the assertions differ in shape. - C20: the existing strict-contract assertion now pins the message with WithMessage("*UiThread.Init()*"). - S2-1: the QfcItemController Arrange comment no longer claims both dispatcher cases fail the same way; it now distinguishes the accessor throw from the never-pumped parked dispatcher. Fail-before and pass-after evidence for all three new tests is recorded under evidence/regression-testing/, together with an exception dossier for C10 and C02, whose hazards cannot be demonstrated by a deterministic failing test without violating the test-independence and no-timing-construct rules. Nine-assembly locally-filtered run: 7000 total, 7000 passed, 0 failed, against a recorded baseline of 6997 plus the three added tests.

From e858bc49f82b9f0f2dd9d653bdefdf07bb76d1ee Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 22:59:25 -0400 Subject: [PATCH 12/28] docs(782): correct the #584 documentation and evidence residuals Phase 5 of issue #782. All edits are made in place; no #584 evidence file is renamed and no existing Timestamp: value is altered. - S3-6: #584 spec Status moves from Draft to Merged (PR #778, merge commit 1c3b210c, 2026-09-04), and the three disagreeing file lists are reconciled - the in-scope list is extended to the authoritative six-file Write Set and the "Files/modules to change" section now cross-references the Write Set instead of carrying a third enumeration. - S3-7/SD10: the three ~40/~62 call-site estimates are replaced with the verified figure, stated against the pre-782-base tag so it stays true after Phase 1 removes two live reads. - S3-1: four passages asserting an execution order the recorded timestamps do not establish are restated without the ordering claim; the conclusion never depended on it, because the sibling positive test passed in the same run. - S3-2: the two formatter command cells now record the six-path invocation that actually ran, Appendix B is labelled as a reference rather than a transcript, and a new section 8 gap entry records the deviation and its whole-tree read-only mitigation. - S3-3: the evidence-artifact count is corrected from 34 to 38. - S3-4: the issue-update mirror gains a note explaining why its filename timestamp and its Timestamp: field differ and why neither is changed. - S3-5/SD3: fifteen EXIT_CODE fields are normalized to a single integer with the per-command breakdown preserved below; the two gates whose success outcome is non-zero additionally declare ExpectedExitCode. - S3-8: seven evaluative spans prohibited by the tonality rule are replaced with evidence-first wording. - S3-9/SD9: #584 finding F5 is dispositioned in both artifacts as discharged by C12 and C13 rather than C26, with the record that it was never promoted. The P5-T14 gate artifact records one deviation for the caller's attention: the P5-T10 premise that all ten remaining per-command values were 0 does not hold for three files, whose zero-match search commands recorded 1. The instruction was followed literally and every original value is preserved verbatim below the normalized field.

The branch base returns 6992/6992 over the nine assemblies both +before and after the failing runs. The failure is therefore attributable to this delivery and is not +the issue #780 flake. **All three of those figures were measured at the superseded base `b95a5252` +and are recorded here verbatim as the measurement that was taken; they are deliberately not +restated against the re-anchored baseline of 6997.** + +**Mechanism.** The `UiSyncContext` getter at `UtilitiesCS/Threading/UiThread.cs` lines 128-131 and +the `AutoScaleFactor` getter at lines 194-197 both call `Init()` lazily when their own backing field +is null. A re-armed latch therefore makes every later read of either accessor retry the WinForms +`SyncContextForm` construction inside `Initialize()` and throw again, starving the thread pool. + +**No coverage claim is made.** This entry does not claim that a unit test covers the re-arm branch +and does not claim the branch exists. It does not exist in the delivered tree. + +**Follow-up.** The retry semantics C03 asks for are promoted as a separate follow-up entry through +the promotion lifecycle by the orchestrator, whose state P8-T21 records. + +**What SD18 supersedes in `spec.md`, and what it does not.** The amendment made to `spec.md` under +SD18 is confined to the AC2 C03 clause. Three further passages still describe the re-arm and are +superseded by SD18 as a recorded decision rather than left standing as an oversight: + +- the Behavioral Contract subsection headed `UiThread.Init()`; +- the C03 cell in the `UtilitiesCS/Threading/UiThread.cs` Write Set row; +- the C03 row of the traceability table. + +A reader comparing the specification against the shipped tree will find each of those three +describing a re-arm that is not present. That divergence is accounted for here. + +`user-story.md` AC-U2 needs no amendment. It bounds the permitted production behaviour changes from +above rather than requiring both of the two it names, so a delivery that ships one of them and not +the other still satisfies it. + +## (b) SD5 — the removed message tail + +The `WpfDispatcherYield` message's tail "before yielding folder tree work" is intentionally gone +under SD5. Both throw sites now share the single `UiThread.DispatcherNotInitializedMessage` +constant, whose text is domain-neutral and names no caller-specific operation. This is an accepted +and reviewed change rather than a regression. It is pinned by the `WithMessage("*UiThread.Init()*")` +assertion that P4-T3 added to `YieldAsync_WithoutDispatcher_RemainsStrict`, so a future edit that +changed the constant's text would fail that test. + +## (c) SD4 — a residual naming inaccuracy that is deliberately retained + +The test method `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` +now asserts a message naming `UiThread.Init()`, so the `NamingInitialize` suffix of its own name is +inaccurate. The name is nonetheless retained. Its fully-qualified name is quoted inside a +`TestCaseFilter` expression in a committed #584 regression-testing evidence artifact, and renaming +the method would make that recorded command resolve to zero tests, converting a reproducible +evidence record into an unreproducible one. The inaccuracy is confined to a test method name and is +recorded here rather than repaired. + +## (d) SD10 — a divergence from the PR #778 review body + +This delivery adopts the figure **49 live reads across 25 production files**, measured against the +`pre-782-base` tag, with 64 textual occurrences across 30 files of which 15 are comments, XML +documentation, commented-out code, or the exception message literal. The derivation is cited +wherever the figure appears. + +The PR #778 review body states **26 files**. The review body publishes no member set, so the source +of the extra file cannot be established: there is no list to diff against. The divergence is +recorded rather than reconciled, and this delivery's figure is the one carried into `#584/spec.md` +because it is the one whose derivation is reproducible. + +## (e) SD9 — #584 finding F5 + +#584 finding F5 asks for synchronization around the existing unsynchronized reflective mutation of +`UiThread._dispatcher`. It is discharged by C12 and C13, which migrate all four `UtilitiesCS.Test` +reflection sites onto a single shared `UiThreadDispatcherScope` install scope, and not by C26, which +adds a new test and changes no existing mutation. C26 is adjacent coverage rather than the +discharging item. + +F5 was never promoted. At the time of the #782 review there was no potential entry and no active +feature folder covering it, and both of the recommendations it recorded remained open. The +disposition is now written into both `#584/code-review.2026-09-04T04-05.md` and +`#584/policy-audit.2026-09-04T04-05.md`. + +## (f) SD14 — supersession of a `spec.md` Constraint 8 clause + +`spec.md` Constraint 8 carries a clause leaving the `ForceDispatcherNull` docstring at +`UtilitiesCS.Test/Threading/IdleAsyncQueue_Tests.cs` lines 150-164 untouched. That clause is +superseded by SD14. The docstring described the pre-#778 mechanism — that reading +`UiThread.Dispatcher` with a null backing field returns null — which is false after PR #778, so +leaving it untouched would have left a false statement in the tree that C13's own migration made +more visible rather than less. P3-T7 rewrote it. + +## (g) SD14 — supersession of the lines 155-160 clause + +The `spec.md` Constraint 8 clause naming `IdleAsyncQueue_Tests.cs` lines 155-160 as deliberately +left is superseded for the same reason. Those lines are the `Purpose:` body of the `` block +at lines 150-164 that P3-T7 rewrites in full; they cannot be preserved inside a block that is +rewritten. The supersession is a recorded decision rather than an omission. + +## (h) SD7 — `[DoNotParallelize]` added to `IdleActionQueue_Tests` + +`evidence/baseline/p0-t11-idle-serialization-census.md` records that the two sibling classes sharing +`ApplicationIdleTimer` global state — `IdleAsyncQueue_Tests` and `ApplicationIdleTimer_Tests` — both +already carry `[DoNotParallelize]`, and that `IdleActionQueue_Tests` did not. The attribute is +required rather than optional here because the `[TestCleanup]` that C14 adds calls +`ApplicationIdleTimer.Unsubscribe`, which calls `Stop()` when the invocation list empties, touching +process-global `System.Windows.Forms.Application.Idle` and `ApplicationIdleTimer.Guard` state shared +with both siblings. + +## (i) SD17 — `/EnableCodeCoverage` is not passed + +No test invocation in this delivery passes `/EnableCodeCoverage`. The reason is that the baseline +coverage figures and the final coverage figures must be produced by one method in order to be +comparable, and `/EnableCodeCoverage` produces a `.coverage` binary that would require a separate +conversion step with its own denominator behaviour. Coverage is instead collected by +`dotnet-coverage collect` with the derived configuration, in P0-T7 for the baseline and in P7-T5 for +the final figures, so both sides of every coverage comparison in this delivery come from the same +collector, the same configuration, and the same selection. diff --git a/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/other/upstream-followups-drm-copilot.2026-09-05T23-02.md b/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/other/upstream-followups-drm-copilot.2026-09-05T23-02.md new file mode 100644 index 000000000..af1aecb1c --- /dev/null +++ b/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/other/upstream-followups-drm-copilot.2026-09-05T23-02.md @@ -0,0 +1,65 @@ +# Upstream Follow-Ups for the drm-copilot Repository — Issue #782 + +Timestamp: 2026-09-05T23-02 + +Command: + +```powershell +git status --porcelain --untracked-files=all -- .claude +git diff --stat pre-782-base..HEAD -- .claude +``` + +EXIT_CODE: 0 + +Output Summary: + +Two items surfaced by the #782 review belong to the drm-copilot repository rather than to this one. +Neither is fixed here, and this record exists so that neither is lost when this feature folder is +archived. + +## Item 1 — finding S4-1: stale agent-memory notes + +Notes under `.claude/agent-memory/task-researcher/` describe `UiThread.Dispatcher` as permanently +null in tests and as producing `NullReferenceException`.

The whole-tree `dotnet tool run csharpier format .` removed one blank line between the closing #endregion and the class's closing brace in UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs. The residue is from the Phase 2 split, which moved the trailing region out of this file. P2-T1's format run was scoped to the newly created part and did not re-format the part the split left behind, so this whole-tree run is the first to reach it.

From 31f0c624998e21e8a0ba5622574394bb34831f15 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 23:20:42 -0400 Subject: [PATCH 16/28] docs(782): check off acceptance criteria and record the AC status summary Phase 8 of issue #782. Fifteen of the seventeen acceptance criteria are checked off in their source documents. The two that remain unchecked were each resolved through their task's explicitly gated Branch B and carry a verbatim deferral line: - AC8, the C09 behavioural follow-up promotion. The filtered promoted-entry search returned zero files. Both mandatory exclusions fired as the plan predicted: the webview2 entry matches "apartment state" on line 86 under issue #476, and this delivery's own promoted entry matches "non-STA" on lines 63 and 107 under issue #782. - AC-U1, the pull request body. No pr_body_782.md exists. Both are owned by the orchestrator and performed outside this plan. evidence/other/ac-status-summary.2026-09-05T23-15.md is the single status summary. It carries the two gated branch records with their full command output and 17 criterion rows, each row's recorded checkbox state verified line by line against the state actually present in spec.md and user-story.md, and every cited artifact path confirmed present on disk.

The executor bisected it: with that line, `UtilitiesCS.Test` plus `TaskMaster.Test` returns 5179/5180 with that test failing at a 21-second duration; without it, and with nothing else changed, the same pair returns 5180/5180. The branch base returns 6992/6992 over the nine assemblies both before and after the failing runs, so this is delivery-attributable and is not the issue #780 flake this plan anticipates elsewhere. All three of those figures — 5179/5180, 5180/5180, and 6992/6992 — are recorded verbatim as the executor measured them at the superseded base `b95a5252` and are deliberately not restated against the re-anchored baseline of 6997. Restating them would misrepresent a measurement that was never taken; the bisect's force comes from the difference between the two arms of the same run, which the re-anchoring does not touch. The mechanism is visible in the source. The `UiSyncContext` getter at `UtilitiesCS/Threading/UiThread.cs` lines 128-131 and the `AutoScaleFactor` getter at lines 194-197 both call `Init()` lazily when their backing field is null. `Initialize()` at lines 59-90 constructs a `SyncContextForm` and calls `Show()` on it. Without the re-arm the latch stays set after a first failure and every later `Init()` is a cheap no-op; with the re-arm, every subsequent read of either lazy accessor retries the WinForms construction and throws again, starving the thread pool and defeating the 500 ms `CancelAfter` at `UtilitiesCS/Extensions/DictionaryExtensions.cs` line 177. The file's own documentation already states the collision: the `Dispatcher` XML `` at lines 152-159 and the inline comment at lines 173-176 record that `Initialize()` has UI-thread affinity and that a lazy `Init()` from an arbitrary reader is deliberately avoided for `Dispatcher`.

The file must open its type declaration region with `#nullable enable annotations` and close it with `#nullable restore annotations`, matching the idiom already used at `UtilitiesCS.Test/TestHelpers/ManualFireTimerWrapper.cs` lines 28 and 31 and, as measured against `pre-782-base`, at `UtilitiesCS.Test/Threading/ProgressTracker_Tests.cs` lines 417 and 419. The Phase 2 split moves that second pair into `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, so at the time this task runs the untouched second precedent is `UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs` lines 671 and 679, which this delivery does not modify.

The removal is safe and is defence in depth rather than a load-bearing precondition. `TestResults/` matches the `[Tt]est[Rr]esult*/` entry in `.gitignore`, so nothing tracked is removed; and CSharpier 1.2.6 honours `.gitignore`, so a left-over results tree is not discovered by the whole-tree scan and does not enter the checked-file count. That was measured directly: `dotnet tool run csharpier check packages` reports `Checked 0 files` although `packages/` contains 1593 `*.xml` and `*.config` files and is not a CSharpier built-in exclusion. The same mechanism is what keeps `coverage\782-effective-coverage.config` out of the count — CSharpier does discover plain `*.config` files by directory scan, and `coverage/*` is git-ignored — which is why the plus-two below is exactly two and not three. Every fact this plan needs from a TRX is already extracted into an evidence artifact, so removing the tree loses nothing. The `Test-Path` guard makes a removal of an already-absent directory a no-op rather than a failure, so running the statement in both P7-T1 and this task in one pass succeeds either way, and the removal stays correct when the loop restarts at P7-T1 after P7-T5 has repopulated the tree.

Acceptance: `EXIT_CODE: 0`, and the recorded count equals the baseline count plus exactly 2, which for the re-recorded baseline of 1581 is `Checked 1583 files`. The expected value is derived from the `BASELINE_CHECKED_FILES:` line of `evidence/baseline/p0-t3-csharpier-check.md` rather than from any figure tabled in this plan, so a further baseline correction propagates without editing this task. The plus-two is the two files this delivery creates, `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` and `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`. Any other difference means a file was added or removed outside the Write Set and must be reconciled before the task is marked complete. Note that `.csproj`, `.props`, and `.targets` are kept out of the check by `.csharpierignore` rather than by any inherent CSharpier behaviour, and that CSharpier 1.2.6 does process `*.xml` and `packages.config`, so this count also proves that no project file was reformatted. +- [x] [P7-T2] Verify formatting read-only.

The same mechanism is what keeps `coverage\782-effective-coverage.config` out of the count — CSharpier does discover plain `*.config` files by directory scan, and `coverage/*` is git-ignored — which is why the plus-two below is exactly two and not three. Every fact this plan needs from a TRX is already extracted into an evidence artifact, so removing the tree loses nothing. The `Test-Path` guard makes a removal of an already-absent directory a no-op rather than a failure, so running the statement in both P7-T1 and this task in one pass succeeds either way, and the removal stays correct when the loop restarts at P7-T1 after P7-T5 has repopulated the tree. Then run `dotnet tool run csharpier check .`. Write `evidence/qa-gates/p7-t2-format-check.md` with `Timestamp:`, `Command:` carrying both command lines, `EXIT_CODE:`, and `Output Summary:` quoting the printed `Checked files` line verbatim alongside the baseline value recorded in `evidence/baseline/p0-t3-csharpier-check.md`. Acceptance: `EXIT_CODE: 0`, and the recorded count equals the baseline count plus exactly 2, which for the re-recorded baseline of 1581 is `Checked 1583 files`. The expected value is derived from the `BASELINE_CHECKED_FILES:` line of `evidence/baseline/p0-t3-csharpier-check.md` rather than from any figure tabled in this plan, so a further baseline correction propagates without editing this task. The plus-two is the two files this delivery creates, `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` and `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`. Any other difference means a file was added or removed outside the Write Set and must be reconciled before the task is marked complete. Note that `.csproj`, `.props`, and `.targets` are kept out of the check by `.csharpierignore` rather than by any inherent CSharpier behaviour, and that CSharpier 1.2.6 does process `*.xml` and `packages.config`, so this count also proves that no project file was reformatted. -- [ ] [P7-T3] Analyzer build.

Only the deletion-line component is deterministic. Under `/m` the file logger re-emits a node-prefixed target header each time it switches node context, so the header count depends on how the parallel nodes interleave rather than on how many times the target ran. That is no longer an argument from mechanism alone: the same solution measured 63 header lines in an 81-line total on the superseded base and 52 header lines in an 84-line total at the re-anchored base, with no project added or removed between the two runs. An equality gate on the aggregate would therefore fail on an unchanged tree, for a reason unrelated to this delivery. The header count and the aggregate are recorded as observations and are not gated. The 18 deletion lines are one per project cleaned, `TaskMaster.sln` declares 18 projects, this delivery adds no project and removes none, and the two runs recorded 18 identically, so 18 is the stable figure. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`, and the number of log lines containing the single-line token `CoreCompileInputs.cache` is exactly 18, equal to the value on the `BASELINE_CORECOMPILE_DELETION_COUNT:` line of `evidence/baseline/p0-t5-nullable-build.md`. The gated figure is that deletion-line count and nothing else; no header count and no aggregate total is gated by this task. The artifact additionally records the total `CoreCompile` token-line count beside the value on the `BASELINE_CORECOMPILE_COUNT:` line of `evidence/baseline/p0-t5-nullable-build.md`, which is 84, labelled as an observation; a difference between the two totals is recorded and is not a failure. -- [ ] [P7-T5] Test with coverage.

Stage only the Phase 7 evidence artifacts and any file the formatter rewrote inside the Write Set, using explicit pathspecs, never `git add -A`. Commit with a message naming issue #782 and the final toolchain pass. Acceptance: `git diff --name-only pre-782-base..HEAD -- docs/features/potential/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- artifacts/` returns zero lines; `git diff --name-only pre-782-base..HEAD -- .claude/` returns zero lines; and `git status --porcelain --untracked-files=all -- UtilitiesCS TaskMaster UtilitiesCS.Test QuickFiler.Test docs/features/active` returns no line whose path is outside the set `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/plan.2026-09-05T15-47.md`, `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/spec.md`, `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md`. Entries for those three paths are expected and are not a failure: the executor records its own progress in this plan file, so the file is modified by the act of checking off the task that runs this gate, and `spec.md` and `user-story.md` carry acceptance-criteria state that is not committed until P8-T19. `evidence/baseline/p0-t2-base-ref.md` records which of the three were already modified at `pre-782-base`. This plan file is expected to appear there, because P0-T1 is checked off before P0-T2 runs; `spec.md` and `user-story.md` are expected to be absent from it, because the worktree was clean at `pre-782-base`. If one of the three appears in this task's porcelain output while the baseline does not record it, that is permitted and not a gate failure: the task records the path and the reason it is dirty on this task's line in this plan and continues.

Entries for those three paths are expected and are not a failure: the executor records its own progress in this plan file, so the file is modified by the act of checking off the task that runs this gate, and `spec.md` and `user-story.md` carry acceptance-criteria state that this task's own commit is what clears. Their entries are permitted rather than required here: this gate runs after that commit, so both are expected to be clean, and admitting them keeps the gate from failing on a re-check-off that touches either file. `evidence/baseline/p0-t2-base-ref.md` records which of the three were already modified at `pre-782-base`. This plan file is expected to appear there, because P0-T1 is checked off before P0-T2 runs; `spec.md` and `user-story.md` are expected to be absent from it, because the worktree was clean at `pre-782-base`. If one of the three appears in this task's porcelain output while the baseline does not record it, that is permitted and not a gate failure: the task records the path and the reason it is dirty on this task's line in this plan and continues.

The format-check condition holds: Checked 1583 files, identical to the count evidence/qa-gates/p7-t2-format-check.md records, confirming the Phase 8 Markdown edits did not disturb the Phase 7 clean pass. The additional confirmation holds: this task's subtracted porcelain output contains no path under the Write Set and no path under the feature folder. The byte-identity comparison does not hold. Two paths under .claude/agent-memory/atomic-planner/ appear on the closing side and not on the recorded baseline side, because the concurrent write landed after P0-T2 captured the baseline image and before this task captured the closing one. P8-T20 is left unchecked and the residue is reported rather than committed, deleted, or reverted.

The additional confirmation holds: this task's subtracted output contains no Write Set path and no feature-folder path. The byte-identity condition fails by exactly the two `.claude/agent-memory/atomic-planner/` paths recorded in P6-T3, which appear on the closing side and not on the baseline side because the concurrent write landed after P0-T2 captured the baseline image and before this task captured the closing one.

This task performs no promotion. The promotion of the C03 follow-up — restoring the retry semantics C03 asked for, by some mechanism that does not re-arm the latch that the two lazy accessors `UiSyncContext` and `AutoScaleFactor` consume — is an orchestrator step performed through the MCP promotion lifecycle outside this plan, exactly as the C09 behavioural follow-up in P8-T8 is. This task records which state that promotion is in, and nothing else. Run `Get-ChildItem -LiteralPath 'docs/features/potential/promoted' -Filter '*.md' | Where-Object { $_.Name -ne '2026-09-05-pr-778-post-merge-review-residuals.md' } | Select-String -Pattern 'latch re-arm|single-shot latch|ThreadSafeSingleShotGuard|retry after a failed Initialize'` and record the full result together with the excluded filename and the reason it is excluded. **The `Where-Object` exclusion is mandatory and is not an optimisation.** `docs/features/potential/promoted/2026-09-05-pr-778-post-merge-review-residuals.md` is this delivery's own promoted entry; it carries the token `single-shot latch` on line 56 in its description of finding C03, and it carries `- Issue: #782` on line 7. `Select-String` matches case-insensitively, so without the exclusion the unfiltered search returns that file today, before any promotion has occurred, Branch A fires against this delivery's own issue number, and the task records a `C03 FOLLOW-UP PROMOTED:` state that is false. Branch A applies when the filtered search returns at least one file **and** that file contains a line matching `^- Issue: #[0-9]+` whose number is not 782: in that case write a line beginning with the verbatim token `C03 FOLLOW-UP PROMOTED:` naming that file's path and its issue number. Branch B applies when the filtered search returns zero files, or returns one or more files none of which contains a line matching `^- Issue: #[0-9]+` whose number is not 782: in that case write the line `C03 FOLLOW-UP DEFERRED: the UiThread.Init() latch re-arm has not yet been promoted; owner is the orchestrator, which performs promotion outside this plan.` verbatim. Write the chosen branch, the search command, and its full output to `evidence/other/c03-followup-state..md`, carrying `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:`. Record the chosen filename on this task's line in this plan at the moment it is written. A separate artifact is used rather than the acceptance-criteria status summary that P8-T8 and P8-T13 write to, because this task runs after P8-T19 has committed that summary and after P8-T18 has verified its row count, and appending to it here would reopen both. Then stage this artifact and this plan file with explicit pathspecs, never `git add -A`, commit with a message naming issue #782 and the C03 follow-up state record, and repeat the P8-T20 porcelain comparison afterwards, because this task is the terminal task of the plan and the clean-tree state P8-T20 established must be re-established here. Acceptance: the search command was run and its full output is recorded in the artifact; exactly one file matches `evidence/other/c03-followup-state.*.md`, resolved by `Get-ChildItem` over that pattern; exactly one of the two branches was taken and the artifact names which; the artifact records the excluded filename `2026-09-05-pr-778-post-merge-review-residuals.md`, records that the unfiltered pattern matches it on line 56, and records that Branch B is the state the plan measured at authoring time, so a Branch A result is a real change of state rather than the pre-existing match; a search of the artifact for the token `C03 FOLLOW-UP` returns exactly one line, so exactly one of the two branch lines is present and not both; `git ls-files --error-unmatch` exits 0 for that artifact, proving it is committed rather than merely present on disk; and the repeated P8-T20 comparison holds under the same four-path subtraction P8-T20 defines. From 238a93acb39eea5df278ee04f71e0468ef42db0e Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 23:23:32 -0400 Subject: [PATCH 18/28] docs(782): record the C03 follow-up promotion state Terminal task of the issue #782 plan. This commit performs no promotion; it records which state the promotion is in. Branch B: the filtered promoted-entry search returned zero files, so the UiThread.Init() latch re-arm has not yet been promoted. The owner is the orchestrator, which performs promotion outside this plan. The mandatory exclusion fired as the plan predicted. This delivery's own promoted entry, 2026-09-05-pr-778-post-merge-review-residuals.md, matches the unfiltered pattern on line 56 with the token "single-shot latch" and carries - Issue: #782 on line 7. Both were re-derived against the current tree. Without the exclusion, Branch A would fire against this delivery's own issue number and record a promoted state that is false. C03 was withdrawn under SD18 after a measured regression, so the follow-up is not a deferred implementation of the same change: it asks for the retry semantics by a mechanism that does not re-arm the latch the UiSyncContext and AutoScaleFactor accessors consume, which is a different design.

The subtraction is required because the executor records its progress in this plan file, so the file is modified both at P0-T2 and at this task. The fourth path, `evidence/baseline/phase0-instructions-read.md`, is retained rather than required.

The subtraction is kept because a path absent from both sides is unaffected by being subtracted, and keeping it preserves the comparison if the artifact is rewritten later in the plan. The `spec.md` and `user-story.md` subtractions are retained for the same class of reason: either file may be modified on one side and clean on the other depending on when its acceptance-criteria state is written and committed. A path absent from both sides of the comparison is unaffected by being subtracted, so a subtraction that turns out to be unnecessary costs nothing. Comparing against the recorded baseline rather than demanding an empty output is required, because `.claude/agent-memory/` is a tracked directory in this repository that a concurrent session can leave modified; an unconditional empty-porcelain demand would fail for a reason outside this delivery's control. The comparison must additionally confirm that this task's own subtracted porcelain output — not the recorded baseline side — contains no path under the Write Set and no path under `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/`.

This commit replaces the prediction with the observed figures: Checked 1583 files, CHECK_EXIT_CODE=0, PORCELAIN_RAW_COUNT=2, SUBTRACTED_COUNT=2, WRITESET_OR_FEATURE_PATHS_IN_SUBTRACTED=0, BYTE_IDENTICAL=False. The plan file sits inside the four-path subtraction set, so amending it cannot change the subtracted comparison and this record terminates rather than requiring a further round.

The repeated P8-T20 comparison was run after this task's commit `238a93ac` and observed, not predicted. Observed: `Checked 1583 files`, `CHECK_EXIT_CODE=0`, `PORCELAIN_RAW_COUNT=2`, `SUBTRACTED_COUNT=2`, `WRITESET_OR_FEATURE_PATHS_IN_SUBTRACTED=0`, `BYTE_IDENTICAL=False`. The format-check and Write-Set-absence conditions hold; the byte-identity condition still fails by the same two `.claude/agent-memory/atomic-planner/` paths, unchanged in content and unchanged in cause. The raw porcelain count fell from 3 to 2 because this task's commit cleared the plan file, which is inside the four-path subtraction set and therefore never affected the subtracted comparison in either direction. Record the state of the C03 follow-up promotion through an explicitly gated two-branch check. This task performs no promotion. The promotion of the C03 follow-up — restoring the retry semantics C03 asked for, by some mechanism that does not re-arm the latch that the two lazy accessors `UiSyncContext` and `AutoScaleFactor` consume — is an orchestrator step performed through the MCP promotion lifecycle outside this plan, exactly as the C09 behavioural follow-up in P8-T8 is. This task records which state that promotion is in, and nothing else. Run `Get-ChildItem -LiteralPath 'docs/features/potential/promoted' -Filter '*.md' | Where-Object { $_.Name -ne '2026-09-05-pr-778-post-merge-review-residuals.md' } | Select-String -Pattern 'latch re-arm|single-shot latch|ThreadSafeSingleShotGuard|retry after a failed Initialize'` and record the full result together with the excluded filename and the reason it is excluded. **The `Where-Object` exclusion is mandatory and is not an optimisation.** `docs/features/potential/promoted/2026-09-05-pr-778-post-merge-review-residuals.md` is this delivery's own promoted entry; it carries the token `single-shot latch` on line 56 in its description of finding C03, and it carries `- Issue: #782` on line 7. `Select-String` matches case-insensitively, so without the exclusion the unfiltered search returns that file today, before any promotion has occurred, Branch A fires against this delivery's own issue number, and the task records a `C03 FOLLOW-UP PROMOTED:` state that is false. Branch A applies when the filtered search returns at least one file **and** that file contains a line matching `^- Issue: #[0-9]+` whose number is not 782: in that case write a line beginning with the verbatim token `C03 FOLLOW-UP PROMOTED:` naming that file's path and its issue number. Branch B applies when the filtered search returns zero files, or returns one or more files none of which contains a line matching `^- Issue: #[0-9]+` whose number is not 782: in that case write the line `C03 FOLLOW-UP DEFERRED: the UiThread.Init() latch re-arm has not yet been promoted; owner is the orchestrator, which performs promotion outside this plan.` verbatim.

The two .claude/agent-memory/atomic-planner/ paths that failed the porcelain condition at the 23-03 capture were written by the atomic-planner, not by this executor, and were cleared by the orchestrator with `git checkout -- .claude/` and `git clean -fd .claude/`. The artifact retains the superseded failing capture and its attribution so the gate history stays auditable. Committed ahead of P8-T20 because the artifact path is not in that task's four-path subtraction set.

The subtraction is required because the executor records its progress in this plan file, so the file is modified both at P0-T2 and at this task. The fourth path, `evidence/baseline/phase0-instructions-read.md`, is retained rather than required. In the superseded record it appeared on the baseline side as an untracked entry, because P0-T1 wrote it before P0-T2 captured the porcelain and Phase 0 had no commit task of its own. Under SD23 that artifact is already committed and P0-T1 is not re-run, so the re-recorded P0-T2 porcelain is not expected to list it and it should appear on neither side. The subtraction is kept because a path absent from both sides is unaffected by being subtracted, and keeping it preserves the comparison if the artifact is rewritten later in the plan. The `spec.md` and `user-story.md` subtractions are retained for the same class of reason: either file may be modified on one side and clean on the other depending on when its acceptance-criteria state is written and committed. A path absent from both sides of the comparison is unaffected by being subtracted, so a subtraction that turns out to be unnecessary costs nothing. Comparing against the recorded baseline rather than demanding an empty output is required, because `.claude/agent-memory/` is a tracked directory in this repository that a concurrent session can leave modified; an unconditional empty-porcelain demand would fail for a reason outside this delivery's control.

The repeated P8-T20 comparison was run after this task's commit `238a93ac` and observed, not predicted. Observed: `Checked 1583 files`, `CHECK_EXIT_CODE=0`, `PORCELAIN_RAW_COUNT=2`, `SUBTRACTED_COUNT=2`, `WRITESET_OR_FEATURE_PATHS_IN_SUBTRACTED=0`, `BYTE_IDENTICAL=False`. The format-check and Write-Set-absence conditions hold; the byte-identity condition still fails by the same two `.claude/agent-memory/atomic-planner/` paths, unchanged in content and unchanged in cause. The raw porcelain count fell from 3 to 2 because this task's commit cleared the plan file, which is inside the four-path subtraction set and therefore never affected the subtracted comparison in either direction. Record the state of the C03 follow-up promotion through an explicitly gated two-branch check. This task performs no promotion. The promotion of the C03 follow-up — restoring the retry semantics C03 asked for, by some mechanism that does not re-arm the latch that the two lazy accessors `UiSyncContext` and `AutoScaleFactor` consume — is an orchestrator step performed through the MCP promotion lifecycle outside this plan, exactly as the C09 behavioural follow-up in P8-T8 is. This task records which state that promotion is in, and nothing else. Run `Get-ChildItem -LiteralPath 'docs/features/potential/promoted' -Filter '*.md' | Where-Object { $_.Name -ne '2026-09-05-pr-778-post-merge-review-residuals.md' } | Select-String -Pattern 'latch re-arm|single-shot latch|ThreadSafeSingleShotGuard|retry after a failed Initialize'` and record the full result together with the excluded filename and the reason it is excluded. **The `Where-Object` exclusion is mandatory and is not an optimisation.** `docs/features/potential/promoted/2026-09-05-pr-778-post-merge-review-residuals.md` is this delivery's own promoted entry; it carries the token `single-shot latch` on line 56 in its description of finding C03, and it carries `- Issue: #782` on line 7. `Select-String` matches case-insensitively, so without the exclusion the unfiltered search returns that file today, before any promotion has occurred, Branch A fires against this delivery's own issue number, and the task records a `C03 FOLLOW-UP PROMOTED:` state that is false. Branch A applies when the filtered search returns at least one file **and** that file contains a line matching `^- Issue: #[0-9]+` whose number is not 782: in that case write a line beginning with the verbatim token `C03 FOLLOW-UP PROMOTED:` naming that file's path and its issue number. Branch B applies when the filtered search returns zero files, or returns one or more files none of which contains a line matching `^- Issue: #[0-9]+` whose number is not 782: in that case write the line `C03 FOLLOW-UP DEFERRED: the UiThread.Init() latch re-arm has not yet been promoted; owner is the orchestrator, which performs promotion outside this plan.` verbatim. Write the chosen branch, the search command, and its full output to `evidence/other/c03-followup-state..md`, carrying `Timestamp:`, `Command:`, `EXIT_CODE: 0`, and `Output Summary:`. Record the chosen filename on this task's line in this plan at the moment it is written. A separate artifact is used rather than the acceptance-criteria status summary that P8-T8 and P8-T13 write to, because this task runs after P8-T19 has committed that summary and after P8-T18 has verified its row count, and appending to it here would reopen both. Then stage this artifact and this plan file with explicit pathspecs, never `git add -A`, commit with a message naming issue #782 and the C03 follow-up state record, and repeat the P8-T20 porcelain comparison afterwards, because this task is the terminal task of the plan and the clean-tree state P8-T20 established must be re-established here. Acceptance: the search command was run and its full output is recorded in the artifact; exactly one file matches `evidence/other/c03-followup-state.*.md`, resolved by `Get-ChildItem` over that pattern; exactly one of the two branches was taken and the artifact names which; the artifact records the excluded filename `2026-09-05-pr-778-post-merge-review-residuals.md`, records that the unfiltered pattern matches it on line 56, and records that Branch B is the state the plan measured at authoring time, so a Branch A result is a real change of state rather than the pre-existing match; a search of the artifact for the token `C03 FOLLOW-UP` returns exactly one line, so exactly one of the two branch lines is present and not both; `git ls-files --error-unmatch` exits 0 for that artifact, proving it is committed rather than merely present on disk; and the repeated P8-T20 comparison holds under the same four-path subtraction P8-T20 defines. From 4ed2f790e96d8c22abd36514db3848b71e073912 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sat, 5 Sep 2026 23:37:49 -0400 Subject: [PATCH 22/28] docs(782): promote the two UiThread.Init follow-ups and close AC8 Promotes both deferred follow-ups through the MCP promotion lifecycle, which discharges AC8's first clause. Issue #787 carries the C09 behavioural half: UiThread.Init() accepts a call from any thread and installs a non-pumping dispatcher into set-once process-global state. Promoted as a bug because it is a missing precondition on an existing contract, not a new capability. Issue #788 carries finding C03, which this delivery withdrew under SD18. The entry records the measured regression, the bisect that attributes it to the single re-arm line, the interaction with the two lazy accessors that causes it, and three candidate approaches, so a future attempt does not repeat the naive form. Recording the withdrawal only as prose in a feature folder would have lost it when the folder is archived. AC8's second clause was already satisfied by the upstream follow-up record written in Phase 6. The acceptance-criteria status summary is appended rather than rewritten, so the executor's deferral record stays intact as the true state at the moment its gate ran.

The failure was bisected to the single re-arm line: with it, `UtilitiesCS.Test` plus `TaskMaster.Test` returned 5179/5180; without it, 5180/5180. The branch base returned 6992/6992 both before and after the failing runs, so this was not the pre-existing flake tracked as issue #780. + +The mechanism is the interaction with the two lazy accessors. `UiThread.cs:128-131` (`UiSyncContext`) and `UiThread.cs:194-197` (`AutoScaleFactor`) each call `Init()` when their backing field is null. Without the re-arm, the latch stays consumed after a first failure and every later `Init()` is a cheap no-op. With the re-arm, every subsequent read of either accessor retries the WinForms construction and throws again, which starves the thread pool and defeats the 500 ms `CancelAfter` at `UtilitiesCS/Extensions/DictionaryExtensions.cs:177`. `TaskMaster/AppGlobals/AppOlObjects.cs:367` and `TaskMaster/ThisAddIn.cs:114` are the readers that make `TaskMaster.Test` the assembly where this surfaces. + +The file's own documentation already records the underlying tension: the XML `` on `UiThread.Dispatcher` states that initialization has UI-thread affinity and that a lazy `Init()` from an arbitrary reader is deliberately avoided for that property, while the two sibling accessors still self-heal. + +## Proposed Fix / Validation Ideas + +- [x] Unit coverage areas: latch state after a failed `Initialize()`, retry success on a subsequent call, and the cost of a repeated failed `Init()` from each lazy accessor. +- [x] Integration scenario to retest: the full nine-assembly suite, specifically `DictionaryExtensions_Tests.TryAddValuesAsync_UpdatesExistingValue`, which is the canary for thread-pool starvation. +- [ ] Manual verification notes: none required. + +A sound fix must make repeated failure cheap, not merely retryable.

Verdict is PASS with zero blocking findings. The review re-ran the toolchain independently rather than accepting the reported figures, and re-derived every coverage number from the raw Cobertura documents. It also established the fact that makes the UiThread.cs modified-file coverage row waivable: the baseline and post-change uncovered line sets are identical, so the 77.11% to 76.83% movement is arithmetic from a covered three-line wrapped throw collapsing to one line against a fixed 19-line residue in untouched host-bound members, not a regression. No delivery artifact had recorded that comparison. Four remediation inputs are recorded. Two are procedural coverage triggers. Two are Should-fix accuracy defects in this delivery's own artifacts and are addressed next.

The production changes are small, behaviour-preserving +where they should be, and correct where they change behaviour. The test changes materially improve +the assembly's hygiene: six independently written reflection sites collapse to two, a leaked +never-shut dispatcher on a pooled worker is removed, a 514-line file is split without losing a single +fully-qualified test name, and three genuine regression tests are added with a fail-before record +that explicitly defends itself against being vacuous. + +**Zero blocking findings.** Nine findings are recorded: two Should-fix and seven Nit or +informational. None prevents the pull request. + +The single most consequential thing this review found is not a code defect but an **overstatement of +proof** that appears in two places. `spec.md` AC10 and the delivery's own code-review artifact both +state that the removal of the `WpfDispatcherYield` message tail is "pinned by the C20 `WithMessage` +assertion." It is not. `WithMessage("*UiThread.Init()*")` is a wildcard match; a future edit that +re-added the tail, or that rewrote the constant in any way that preserved the substring +`UiThread.Init()`, would leave every test green. No test in the repository asserts the constant's +value. That is finding **CR-1**. + +The second Should-fix, **CR-2**, is an evidence-integrity defect: the re-recorded baseline coverage +figures cannot be reproduced from the baseline document the recording artifact itself names, and the +file's timestamps contradict the claimed measurement time. It changes no verdict, because every +candidate baseline value sits at or below the head value, but it means a reader following the +artifact's own instructions cannot arrive at its own numbers. + +### Verified correct + +Each of the following was checked against the tree rather than accepted from the delivery artifacts: + +- **C02, the single-read getter.** `Dispatcher? captured = _dispatcher;` then test then return of the + same local. The stated invariant — the getter never returns null and never observes a value other + than the one it tested — holds. +- **C23, the captured-dispatcher lambdas.** This one needed checking, because the edit reads + `UiDispatcher = UiDispatcher` and could have been a no-op. `ProgressTracker.cs:83-88` declares + `internal Dispatcher UiDispatcher` over the private `_uiDispatcher` field, assigned from + `UiThread.Dispatcher` at line 33. The lambda therefore now closes over the captured instance state + and no longer re-reads the process-global static. The fix is real. +- **C01, the dead null comparisons.** Removing `dispatcher != null` from + `RibbonViewer.EngineCommands.cs` is behaviour-preserving, because the accessor now throws rather + than returning null, so the comparison could never be false where it was reached. +- **C12/C13, the reflection consolidation.** A search for the token `"_dispatcher"` across every + `*.cs` in the repository returns exactly two hits, both intended and both guarding themselves with + a static-initializer non-null assertion. +- **C16/C15, the split.** 24 test methods before, 25 after, zero lost, one added. Both parts declare + the same `partial class`, so every fully-qualified name survives — which matters, because several + are quoted verbatim inside committed `TestCaseFilter` expressions. +- **AC7 fail-before.** `evidence/regression-testing/p4-t7-fail-before.md` removes both guards, not + one, and says why: "Removing only the `UiThread` throw leaves the sibling guard in + `WpfDispatcherYield`, which throws the same exception type with the same shared constant, so the + C21 test would still pass and the demonstration would be vacuous." All three tests fail with + `NullReferenceException` and two carry production stack frames at the exact exposed lines. This is + a genuine RED-first record. +- **The C03 withdrawal.** Honest, measured, bisected to a single line, mechanistically explained, and + promoted as issue #788 rather than quietly dropped. The artifact explicitly declines to claim + coverage for a branch that does not exist. This is the right way to withdraw a planned item. + +## Findings Table + +| Severity | File | Location | Finding | Recommendation | Rationale | Evidence | +|---|---|---|---|---|---|---| +| Should-fix | `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`, `UtilitiesCS.Test/Threading/UiThread_Tests.cs` | `:136`, `:142` | The shared message constant's text is not pinned by any test.

Timestamps: baseline document 19:26:55, re-anchored base commit `736c2cf2` 19:17:24, first production edit `351a242c` 20:37:55 — so the document is a legitimate measurement at the re-anchored base tree, taken before any edit, but it is the 19:26 run and not a 21:59 one. | +| Nit | `UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, `UtilitiesCS.Test/Threading/ProgressTrackerAsync_Tests.cs` | `:213-227`, `:139-153` | The two C26 tests assert only the exception type. `Throw()` and `ThrowAsync()` carry no message assertion, so either test would pass on an unrelated `InvalidOperationException` raised anywhere inside `Initialize()` or `InitializeAsync()`. | Add `.WithMessage(UiThread.DispatcherNotInitializedMessage)` to both, which also discharges part of CR-1. | The tests are meant to pin one specific guard. Without a message assertion they pin "something in this method throws `InvalidOperationException`", which is weaker than the finding they close. | Read of both test bodies. | +| Nit | `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs` | `:38-57` | The new `[TestCleanup]` introduces a fresh reflection dependency on the private production method name `IdleActionQueue.OnApplicationIdle`, with no rename guard. If that method is renamed, `GetMethod` returns null and `Delegate.CreateDelegate(type, (MethodInfo)null)` throws `ArgumentNullException`, whose message does not name the cause. | Add `.Should().NotBeNull(because: "IdleActionQueue.OnApplicationIdle must exist")` on the `MethodInfo` before constructing the delegate, matching the `ResolveDispatcherField` idiom this delivery standardised. | The delivery's own theme is that a reflective lookup must fail loudly and informatively on a rename. The new site fails loudly but not informatively, so the idiom is applied inconsistently within the same change. | Read of the added cleanup. | +| Nit | `UtilitiesCS.Test/Threading/IdleActionQueue_Tests.cs` | `:55` | `ApplicationIdleTimer.Unsubscribe(handler)` runs unconditionally after every test, including tests that never subscribed. `Unsubscribe` calls `Stop()` when the invocation list empties, touching process-global `Application.Idle` state. | Consider making the unsubscribe conditional on the queue having subscribed, or document that an unsubscribe of an unregistered handler is a no-op in this implementation. | Low risk given the `[DoNotParallelize]` that the same edit correctly adds, but the cleanup asserts nothing about the state it is restoring. | Read of the added cleanup and the `spec.md` SD7 rationale. | +| Nit | `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` | `:186-206`, `:175-180` | `_ready.WaitOne()`, `_thread.Join()`, and the C21 `worker.Join()` all run without a timeout. A thread that failed to start or to complete would hang until the 5-minute `/Blame TestTimeout` fires rather than failing fast. | Optional: supply a bounded timeout and assert on it. | Consistent with the existing `StaDispatcherHost` precedent in the same assembly, so this is pre-existing style rather than a new hazard introduced here. Recorded for completeness. | Read of both host implementations. | +| Nit | `QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` | `:55-63` | The order-independence teardown `current.Should().BeSameAs(_capturedDispatcher)` still compares null to null when the process-global dispatcher is unset for the whole test class. | None required. | C18's stated condition — that the guard fails rather than passes if the fixture cannot resolve the field — **is** met, because `UiThreadDispatcherFixture.ResolveDispatcherField` asserts non-null inside a static initializer. The residual null-to-null case is the correct outcome for "nothing mutated", not a defect. Recorded so a future reader does not mistake it for an unfixed C18. | Read of `QfcItemController.UiThreadDispatcherFixture.cs:133-141`. | +| Nit | `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md` | AC-U2 | The criterion still names "the retry-after-failed-initialization behavior of `UiThread.Init()`" as one of two permitted production behaviour changes.

The text is nonetheless stale and sends a future reader looking for a change that is not there. | `spec.md` Behavioral Contract `UiThread.Init()` subsection; `evidence/other/code-review.2026-09-05T23-00.md` entry (a). | +| Informational | `artifacts/pr_context.summary.txt` | `Changed files overview`, `Close candidates` | The summary reports `Core logic changes: 0 files` while the branch changes 16 C# files, and lists seven author-asserted auto-close issues (#394, #449, #476, #493, #508, #584, #778) that are prose scrapes from this delivery's own artifacts. | The PR author step must derive the changed-file set from git and must carry only **#782** as the closing issue. | Left uncorrected, the PR body would close six unrelated issues. #394 for example appears in `spec.md` Constraint 6 purely as a cited past defect. This is a recurring generator defect rather than a defect of this branch. | Reviewer simulation of the coverage hook's `Get-ChangedLanguageSet` against the summary returned an **empty** language set, confirming the overview lists only Markdown paths in the parsed format. | + +## Design and Architecture Notes + +**The shared constant is the right shape.** One `internal const string` adjacent to its primary +thrower, rather than a new holder type, is the simpler design and the spec records the rejected +alternative with a reason. `internal` is the correct accessibility: both consumers are in +`UtilitiesCS`, and `InternalsVisibleTo` makes it reachable from the test assembly, which is precisely +what CR-1's recommendation depends on. + +**The deliberate non-lazy contract is now documented rather than implicit.** The `` block +explains why `Dispatcher` does not self-heal when the sibling `UiSyncContext` and `AutoScaleFactor` +accessors do. That asymmetry was previously undiscoverable and is exactly the kind of thing that +causes a later contributor to "fix" it. The C03 withdrawal record then documents empirically what +happens when the related latch behaviour is changed — the two lazy accessors turn a re-armed latch +into repeated WinForms construction that starves the thread pool. Taken together these two additions +leave the type meaningfully safer to modify than they found it. + +**`UiThreadDispatcherScope` is well designed for its constraints.** It documents that it is +deliberately not internally synchronized and that serialization is supplied by `[DoNotParallelize]` +on every installing class — and it states the obligation that imposes on a future caller. `Dispose` +restores a null prior unconditionally, which is the case a hand-rolled `finally` most often gets +wrong. Disposal is idempotent. The `Current` accessor exists specifically so a test can observe the +uninitialized state without tripping the guard, which is what makes the AC5 round-trip assertion +expressible. + +**One residual asymmetry.** `QuickFiler.Test` cannot use the scope, because it is not named in the +`InternalsVisibleTo` grants on `UtilitiesCS`, so the repository ends with two reflection acquisitions +rather than one. The spec states this and the reason. Two guarded acquisitions is a large improvement +over six unguarded ones, and closing the gap would mean adding a grant to production `AssemblyInfo.cs` +for a test assembly — a worse trade. The current outcome is the right call. + +## Policy Compliance Notes + +- **Bugfix workflow.** Correctly scoped. This is a Refactor; the failing-test-first requirement was + applied to the two latent defects (C10, C02) and discharged through a fail-before dossier where a + deterministic in-suite failing test is structurally impossible, which is the route the evidence + conventions prescribe. +- **500-line limit.** The only pre-existing violation is removed. Every touched file now measures + under 400 lines. +- **Temporary files in tests.** None created. The C10 STA sentinel, the C21 fresh thread, and the C14 + cleanup all avoid the filesystem entirely. +- **Determinism.** Zero banned timing APIs introduced. The C21 test's use of a dedicated fresh thread + is a determinism improvement, not a timing hack: it removes a dependency on which pooled worker the + test lands on. +- **`.claude/` untouched.** Zero paths in the diff, and `evidence/qa-gates/p6-t3-dotclaude-untouched.md` + records that residue written by earlier agents was cleared. The worktree is clean at HEAD. + +## Recommendation + +**Approve for pull request.** CR-1 and CR-2 are worth fixing but neither blocks: CR-1 is a test +strengthening plus two sentence corrections, and CR-2 is an evidence artifact amendment whose +resolution cannot change any verdict.

Where a delivery artifact made a claim, the claim was re-derived rather than accepted. + +| # | Verdict | Independent verification | +|---|---|---| +| AC1 | **PASS** | **C10:** `UiThread_Tests.cs:186-206` — a `StaDispatcherHost` nested class starts a dedicated STA thread, captures `Dispatcher.CurrentDispatcher` there, and its `Dispose` calls `BeginInvokeShutdown(DispatcherPriority.Send)` then `_thread.Join()`; it is constructed inside a `using`, so shutdown runs on every exit path. The populated-branch test is retained under its original name. **C02:** the getter reads `_dispatcher` once into `captured`, tests the local, returns the local. **C18:** `EmailMoveMonitorTests.cs` now reads `UiThreadDispatcherFixture.Current`; a search of that file for `FieldInfo` returns zero hits. **C19:** the P27-T2 docstring, Act comment, and `NotThrow` reason all now read `InvalidOperationException` / `synchronous`; the diff removes every `NullReferenceException` mention from those three passages. **C20:** the false comment clause is replaced, `WpfDispatcherYield.cs:65` throws `UiThread.DispatcherNotInitializedMessage`, and a `WithMessage` assertion was added at `WpfDispatcherYieldTests.cs:136`. **C16:** split verified under AC6. **S3-2:** the #584 policy-audit formatter cell now records the six-path invocation that actually ran, row 3.1 is amended to disclose the deviation, Appendix B is relabelled, and a section 8 gap entry `B0` was added. | +| AC2 | **PASS** | Thirteen of fourteen nits are present in the diff and were spot-checked: C05 (non-lazy comment), C06 (message names only `Init()`), C08 (``, ``, `` on a file that previously carried zero `///`), C09-message (the "on the UI (STA) thread during host startup" clause), C11 (`Action act = () => _ = UiThread.Dispatcher;` expression-bodied), C12/C13 (four sites migrated), C14 (`[TestCleanup]` added), C15 (attributes on separate lines), C21 and C26 (new tests), C25 (both "avoid WindowsBase" clauses deleted), S2-1 (the false clause corrected). The fourteenth, **C03, is an omission**, and AC2's omission branch is discharged in full: `evidence/other/code-review.2026-09-05T23-00.md` section (a) opens with the required verbatim token `C03 OMITTED: latch re-arm not implemented` and records the discharge route, the measured regression, the bisect to the single line `_loaded = new ThreadSafeSingleShotGuard();` (5179/5180 with it, 5180/5180 without), the mechanism via the two lazy accessors, an explicit refusal to claim coverage for a branch that does not exist, and the promotion to a separate follow-up. This reviewer confirmed `Init()` carries no `try` or `catch` in the delivered tree. | +| AC3 | **PASS** | A search of the entire #584 evidence subtree for `EXIT_CODE:` lines that are not a bare signed integer returns **zero matches** in any evidence artifact (the only hits are prose occurrences inside that feature's plan file, which is not an evidence artifact and not in the S3-5 member set). S3-3 verified: `34` -> `38`. S3-1 verified: the ordering assertion in row 2.15 is softened to state that the recorded `Timestamp:` values do not establish relative execution order. S3-8 verified: the evaluative span "This is a model instance of the rule" is replaced with neutral wording. S3-9 verified: the disposition now cites C12/C13 as the discharging item and records that the follow-up was never promoted. S3-4, S3-5, S3-6, S3-7 present in the diff for the named files. | +| AC4 | **PASS** | `RibbonViewer.EngineCommands.cs` — both `dispatcher != null &&` comparisons removed at lines 72 and 115; the two XML-doc mentions of `UiThread.Dispatcher` are untouched. `ProgressTracker.cs:39` and `ProgressTrackerAsync.cs:39` now read `UiDispatcher = UiDispatcher`. This reviewer verified the fix is not a no-op: `ProgressTracker.cs:83-88` declares `internal Dispatcher UiDispatcher` over the private field `_uiDispatcher`, so the lambda closes over captured instance state and no longer re-reads the static. | +| AC5 | **PASS** | A search for the token `"_dispatcher"` across every `*.cs` in the repository returns **exactly two hits**: `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs:117` and `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:136`. `EmailMoveMonitorTests.cs` contains no `FieldInfo`. The round-trip restore assertion AC5 requires is present at `UiThread_Tests.cs`: an outer `InstallNull()` establishes a null prior, an inner `Install(expected)` is asserted inside its scope, and after the inner scope disposes the test asserts `UiThreadDispatcherScope.Current.Should().BeNull()`. | +| AC6 | **PASS** | Line counts by `awk END{print NR}`: `ProgressTracker_Tests.cs` **271**, `ProgressTracker_ReportAndViewerTests.cs` **288** — both strictly under 500. `UtilitiesCS.Test.csproj:76` and `:479` carry exactly one `` each. `ProgressTracker_Tests.cs:14-16` declares `[TestClass]` and `[DoNotParallelize]` on separate lines over `public partial class ProgressTracker_Tests`; `ProgressTracker_ReportAndViewerTests.cs:14` declares the same partial class with no attributes. Reviewer-run regex comparison of test method names across the pre-split file versus both post-split parts: **24 before, 25 after, zero missing, one added**. | +| AC7 | **PASS** | The three tests exist. `evidence/regression-testing/p4-t7-fail-before.md` records `Total tests: 3`, `Failed: 3` with both guards temporarily removed, and quotes each verbatim failure message; two carry production stack frames at `ProgressTrackerAsync.cs:35` and `ProgressTracker.cs:35`, the exact lines the edits exposed. The dossier removes **both** guards and states why removing only one would have made the C21 demonstration vacuous — this reviewer regards that as the difference between a real RED-first record and a decorative one. Pass-after is recorded in the final nine-assembly run, in which all five named tests report `Passed`. | +| AC8 | **PASS** | `docs/features/potential/promoted/2026-09-05-uithread-init-accepts-non-sta-callers.md:9` carries `- Issue: #787` (the C09 behavioural half) and `...latch-not-rearmed-after-failed-initialize.md:9` carries `- Issue: #788` (the withdrawn C03). `evidence/other/upstream-followups-drm-copilot.2026-09-05T23-02.md` records S4-1 and the `Timestamp:`-semantics request as upstream items. `git diff --stat ...HEAD -- ".claude/"` returns **empty**, confirming neither was fixed in this repository. | +| AC9 | **PASS** | All four gates were **re-run by this reviewer**, not accepted: CSharpier check exit 0 `Checked 1583 files in 4139ms.`; analyzer `msbuild /t:Rebuild` exit 0 across 18 projects; nullable `msbuild /t:Rebuild /p:TreatWarningsAsErrors=true` exit 0 with `0 Warning(s)` and `0 Error(s)`. `evidence/qa-gates/p7-t8-loop-closure.md` records the loop restarting once (pass 1 rewrote a file) and closing clean on pass 2, which is the correct handling. **Changed-line coverage was independently re-derived: 7 of 7 changed executable production lines covered, 100%, zero uncovered.** It did not decrease. | +| AC10 | **PASS**, with a recorded qualification | `UiThread.cs:135-136` declares exactly one `internal const string DispatcherNotInitializedMessage` whose value is character-identical to the text in the spec's Behavioral Contract. A search for `DispatcherNotInitializedMessage` returns three hits: the declaration and the two throw sites, one in each file. A search for `UiThread.Initialize()` across all `*.cs` returns **zero**. A search for `before yielding folder tree work` returns **zero**. The `WithMessage` assertion required by the criterion exists at `WpfDispatcherYieldTests.cs:136`. **Qualification:** the criterion's closing clause asserts the tail's removal "is pinned by" that assertion. It is not — `WithMessage("*UiThread.Init()*")` is a wildcard that would still match a message with the tail restored. Every verifiable requirement of AC10 is met; the defect is in the criterion's own reasoning about what the assertion proves, and is recorded as finding CR-1 in the code review. | +| AC11 | **PASS** | `UiThread_Tests.cs:133` retains `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` verbatim; `:142` asserts `WithMessage("*UiThread.Init()*")`. `evidence/other/code-review.2026-09-05T23-00.md` section (c) records the residual naming inaccuracy and the SD4 reason — the fully-qualified name is quoted inside a committed `TestCaseFilter` expression and renaming would make that recorded command resolve to zero tests. | +| AC12 | **PASS** | Both re-derivation artifacts exist and quote current text at each location: `evidence/baseline/p0-t9-584-spec-rederivation.md` re-reads the #584 spec's status line and AC checkbox block for S3-6, and `evidence/baseline/p0-t10-584-plan-rederivation.md` re-reads the two #584 plan line references (936-946 and 1064-1086) before either is quoted. Neither SD11 item is asserted anywhere without a fresh derivation. | +| AC-U1 | **FAIL — correctly open** | No pull request exists for this branch; `gh` is reported unavailable in the PR context artifacts and no PR metadata was retrievable. This criterion cannot be satisfied before the pull request is opened, and it is correctly left `[ ]` in `user-story.md`. It is not a defect in the delivery. The second half of the criterion — that the PR body map every finding identifier to a file or a recorded reason — is fully prepared for: `evidence/other/code-review.2026-09-05T23-00.md` carries a disposition row for all 26 `C` identifiers plus all 12 `S` identifiers. | +| AC-U2 | **PASS**, with a recorded qualification | The production behaviour changes in the diff are: the `InvalidOperationException` message text, and nothing else. The `RibbonViewer` comparison removals are behaviour-preserving because the accessor can no longer return null. The `ProgressTracker` and `ProgressTrackerAsync` edits substitute a captured field read for a static read of the same value assigned six lines earlier. `Init()` is byte-identical to its `pre-782-base` form. **Qualification:** AC-U2's text names the `Init()` retry behaviour as a permitted change; C03 was withdrawn so that change does not exist. The criterion bounds the permitted set from above rather than requiring both members, so a delivery that ships one and not the other still satisfies it — the reading the delivery's own artifact gives, which this reviewer accepts. The text is nonetheless stale; recorded as CR-8. | +| AC-U3 | **PASS** | Every one of the 38 finding identifiers has a disposition: 22 resolved in the diff, 4 refuted with no action (C04, C07, C22, C24), C17 and S4-2 no-action, C03 omitted with a full recorded reason and promoted as #788, C09's behavioural half promoted as #787, and S4-1 plus the `Timestamp:`-semantics request recorded as upstream follow-ups. This reviewer spot-verified the disposition table's row for each of the four refuted items against `pr-778-review-source.md`. Nothing is left unrecorded, so the #584 folder can be archived. | +| AC-U4 | **PASS** | The four claims S3-2, S3-3, S3-1, and S3-8 targeted were each re-verified as now reader-checkable: the formatter command cell records the six-path invocation that actually ran rather than the whole-tree form; the evidence count reads 38, matching the tree; the ordering sentence is softened to state that timestamps do not establish execution order; and the evaluative spans are replaced with neutral wording. A reader can now reconcile each recorded command, count, and ordering claim against committed evidence without re-deriving it. **Adjacent note, outside this criterion's scope:** this delivery's *own* baseline coverage artifact does not meet the same standard — see CR-2 / EV-1 in the code review. AC-U4 is scoped to the #584 artifacts and is satisfied. | +| AC-U5 | **PASS** | Same evidence as AC9. Toolchain re-run by this reviewer, single clean pass; changed-line coverage 100% (7/7) and therefore not decreased. | + +## Summary + +**16 of 17 acceptance criteria PASS. One (AC-U1) is correctly open pending creation of the pull +request. Zero criteria FAIL for a reason attributable to the delivery.** + +Two criteria, AC10 and AC-U2, pass with recorded qualifications. In both cases every verifiable +requirement is met and the qualification concerns the criterion's own wording rather than the +delivered tree: + +- **AC10** claims a wildcard `WithMessage` assertion pins the removal of a message tail. It does not. + The requirement it states — that the assertion exist — is met; the inference it draws is wrong. +- **AC-U2** names a production behaviour change (the `Init()` latch re-arm) that was withdrawn + mid-delivery and therefore does not exist. The criterion is an upper bound, so it is still + satisfied, but the text is stale. + +Both are recorded in `code-review.2026-09-05T23-48.md` as CR-1 and CR-8. Neither blocks. + +Beyond the criteria, this reviewer established one fact the delivery's artifacts do not state, and it +strengthens rather than weakens the delivery's position. The per-file line coverage of +`UtilitiesCS/Threading/UiThread.cs` moves from 77.11% to 76.83%, which reads as a regression. It is +not one. The **uncovered line set is byte-identical on both sides** — the same 19 line numbers, +`28,29,30,32,33,34,67-76,118,119,120` — so no line transitioned from covered to uncovered. The +percentage moved only because a covered three-line wrapped `throw` collapsed to one line when routed +through the shared constant, shrinking a numerator and denominator that share a fixed uncovered +residue. The residue itself sits entirely in members the diff never touched: the `Init` +parameter-handling block, the `ThreadMonitor` construction that requires a live UI thread, and the +lazy `UiSyncContext` accessor. + +**Recommendation: GO for pull request.** The pull request must close **only #782**; the seven +auto-close candidates in the PR context summary are prose scrapes and must not be carried into the +PR body. + +## Acceptance Criteria Check-off + +No source file was modified by this review. All 16 criteria this reviewer evaluated as PASS were +already checked `[x]` in their source files by the executor, and each was independently verified +before this audit confirmed the check-off.

The scope audited is the full branch diff against the resolved base branch, not any plan, +phase, or caller-supplied subset. + +All four toolchain gates were **re-run independently by this reviewer** and all pass: +CSharpier check exit 0 (`Checked 1583 files`), analyzer `msbuild /t:Rebuild` exit 0 over 18 projects, +nullable `msbuild /t:Rebuild` exit 0 with `0 Warning(s)` / `0 Error(s)`. The reported test result +(7000 total, 7000 passed, 0 failed, 0 skipped) is corroborated by the coverage document that run +produced, from which every coverage figure below was independently re-derived. + +Every acceptance criterion asserted by the delivery was verified against the tree rather than +accepted from the artifacts. **16 of 17 acceptance criteria PASS**; the single open criterion, +AC-U1, requires a pull request that does not yet exist and is correctly left unchecked. + +**Zero blocking code defects were found.** Two **FAIL** verdicts are recorded, both procedural and +both dispositioned non-blocking with evidence: + +1. The canonical C# coverage artifact `artifacts/csharp/coverage.xml` is absent (deliberately, under + scope decision SD1). Coverage verification is mandatory, so the row reads FAIL. +2. The modified file `UtilitiesCS/Threading/UiThread.cs` sits at 76.83% line coverage, below both the + 85% uniform floor and the 80% remediation-trigger floor. + +For finding 2 this reviewer established a fact the delivery's own artifacts do not state: the +**uncovered line set of `UiThread.cs` is byte-identical between baseline and head** — the same 19 +line numbers, `28,29,30,32,33,34,67-76,118,119,120`, on both sides. Not one line transitioned from +covered to uncovered. The -0.28 percentage-point movement is purely the arithmetic consequence of a +covered three-line wrapped `throw` collapsing to one line when routed through the shared constant. +All 7 changed executable production lines are covered. + +One evidence-integrity defect (**EV-1**) was found: the re-recorded baseline coverage figures are not +reproducible from the baseline document on disk. It does not change any verdict, because every +candidate baseline value is at or below the head value. + +**Overall verdict: PASS with two non-blocking procedural FAIL rows. Recommendation: GO for pull +request.** + +## Rejected Scope Narrowing + +The caller made **no attempt to narrow the audit scope**. The caller's prompt explicitly instructed +"Determine scope yourself" and framed its two statements about the PR context artifact as +"measurements you should verify rather than take from me." Both were independently verified and both +proved correct: + +| Caller statement | Independent verification | Outcome | +|---|---|---| +| The summary's `Core logic changes: 0 files` is a top-N-by-churn truncation, not the changed-file set | `git diff --stat ...HEAD -- "*.cs" "*.csproj"` returns 16 files, +742/-402 | Confirmed; scope derived from git, not from the summary | +| The seven `Close candidates` (#394, #449, #476, #493, #508, #584, #778) are prose scrapes | #394 appears in `spec.md` Constraint 6 as a cited past defect; the pattern holds for the others | Confirmed as false positives | + +Two items were considered as possible narrowing and are recorded here for completeness. Neither is a +caller instruction, and neither was honoured as a limit on this audit. + +1. **`spec.md` Constraint 11 / scope decision SD1** states that `artifacts/csharp/coverage.xml` is not + produced partly because "the hook applies a fixed repository-wide line floor that would force a + FAIL verdict for a shortfall that pre-exists on origin/main." This is an in-repository artifact + arguing for the avoidance of a coverage gate. This reviewer did **not** honour it: the coverage + figures were computed directly from the Cobertura documents and the FAIL verdicts are recorded in + full below. +2. **The caller's instruction never to write under `.claude/**`** is a write-scope restriction, not + an audit-scope restriction. It was honoured as a write restriction and disregarded as an audit + restriction: this reviewer read `.claude/hooks/`, `.claude/rules/`, and `.claude/skills/` freely. + The branch diff contains zero `.claude/` paths, verified by + `git diff --stat ...HEAD -- ".claude/"` returning empty. + +## Evidence Location Compliance + +`validate_evidence_locations.py` does not exist in this repository, so the scan was performed +directly against the branch diff. + +| Check | Command | Result | +|---|---|---| +| Files written under `artifacts/baselines/`, `artifacts/qa/`, `artifacts/evidence/`, `artifacts/coverage/` | `git diff --name-only ...HEAD -- "artifacts/"` | **Zero paths.** PASS | +| Delivery evidence under the canonical `/evidence//` layout | `git diff --name-status` inspection | PASS — 38 evidence files under `baseline/`, `qa-gates/`, `regression-testing/`, `other/` | + +No `EVIDENCE_LOCATION_OVERRIDE_REJECTED` condition arose.

General Code Change Policy Compliance + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 2.1 | Simplicity first | PASS | The getter change is a single-read local. The shared message is one `const`, not a new holder type; the spec records that alternative and why it was rejected. | +| 2.2 | Reusability | PASS | Six independently written reflection sites reduced to two acquisitions repository-wide, verified by a search for the token `"_dispatcher"` across all `*.cs` returning exactly two hits: `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs:117` and `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:136`. | +| 2.3 | Extensibility | PASS | No public signature changed. `Dispatcher` keeps its declared type and private setter. | +| 2.4 | Separation of concerns | PASS | Test scaffolding lands in `UtilitiesCS.Test/TestHelpers/`, not in the production `UiThread` type. | +| 2.5 | Fail fast and explicitly | PASS | The uninitialized path throws rather than returning null; no new `catch` was introduced anywhere in the diff. | +| 2.6 | 500-line file limit | PASS | Every touched file measured with `awk END{print NR}`: `ProgressTracker_Tests.cs` 271, `ProgressTracker_ReportAndViewerTests.cs` 288, `UiThread_Tests.cs` 213, `WpfDispatcherYieldTests.cs` 256, `EmailMoveMonitorTests.cs` 317, `IdleActionQueue_Tests.cs` 278, `IdleAsyncQueue_Tests.cs` 341, `ProgressTrackerAsync_Tests.cs` 231, `UiThread.cs` 195, `WpfDispatcherYield.cs` 76, `UiThreadDispatcherScope.cs` 126, `QfcItemController.InitializationTests.Part2.cs` 397. The 514-line pre-existing violation is removed. | +| 2.7 | No policy documents modified | PASS | Zero paths under `.claude/` or `.github/instructions/` in the diff. | +| 2.8 | No secrets or `.env` files | PASS | None in the diff. | +| 2.9 | Naming conventions | PASS | `PascalCase` types and members; `camelCase` locals. | +| 2.10 | Comment why, not what | PASS | The single-read comment, the non-lazy comment, and the corrected `WpfDispatcherYield` comment all state reasons. | +| 2.11 | No absolute host paths in artifacts | PASS | Evidence artifacts substitute `` for host paths and explicitly decline to reproduce vstest-generated TRX filenames. | + +## 3. Language-Specific Code Change Policy Compliance (C#) + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 3.1 | CSharpier formatting via the manifest-pinned tool | PASS | Re-run by this reviewer: `dotnet tool run csharpier check .` -> `Checked 1583 files in 4139ms.`, exit 0. | +| 3.2 | `dotnet format` not used | PASS | No `.csproj` was rewritten; the only csproj change is two `` additions. | +| 3.3 | .NET analyzer diagnostics | PASS | Re-run by this reviewer with `/t:Rebuild`: exit 0 across all 18 projects, no analyzer diagnostics emitted. | +| 3.4 | Nullable / type-check gate | PASS | Re-run by this reviewer with `/t:Rebuild` and `/p:TreatWarningsAsErrors=true`: `0 Warning(s)`, `0 Error(s)`, exit 0. `/p:Nullable=enable` correctly not passed. | +| 3.5 | `/t:Rebuild` used, not `/t:Build` | PASS | Both reviewer invocations used `/t:Rebuild`, so `CoreCompile` actually ran and the gates are not vacuous. | +| 3.6 | Null-safety by default | PASS | `#nullable enable annotations` in the new helper matches an established repository idiom used in 30+ existing files. | +| 3.7 | Minimal public surface | PASS | The message constant is `internal`; the scope type is `internal sealed`. | +| 3.8 | XML documentation on non-obvious contracts | PASS | `Dispatcher` gains ``, ``, and ``; the file previously carried zero `///` comments. | +| 3.9 | No broad `catch (Exception)` added to production | PASS | Zero `catch` clauses added to production code. The one `catch (Exception ex)` in the diff is inside the C21 test's worker thread, which captures and re-asserts on the calling thread — a legitimate test boundary. | + +## 4. Language-Specific Unit Test Policy Compliance (C#) + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 4.1 | MSTest framework | PASS | `[TestClass]`, `[TestMethod]`, `[TestCleanup]`, `[DoNotParallelize]`, `[STATestMethod]` throughout; no xUnit or NUnit introduced. | +| 4.2 | FluentAssertions preferred | PASS | Every added assertion uses `Should()`. | +| 4.3 | Moq for mocking | PASS | No new mocking need arose; existing Moq usage untouched. | +| 4.4 | Arrange-Act-Assert | PASS | All three added tests carry explicit section comments. | +| 4.5 | `[TestClass]` applied to exactly one part of the split class | PASS | `ProgressTracker_Tests.cs:14-16` carries `[TestClass]` and `[DoNotParallelize]` on separate lines over `public partial class ProgressTracker_Tests`; `ProgressTracker_ReportAndViewerTests.cs:14` declares the same partial class with no attributes. | +| 4.6 | Test discovery preserved across the split | PASS | Reviewer-run regex comparison of `public (void\|async Task\|Task) (` across the pre-split file versus both post-split parts: 24 before, 25 after, **zero missing**, exactly one added (`Initialize_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`). `partial class` preserves every fully-qualified name. | +| 4.7 | New files registered in the csproj exactly once | PASS | `UtilitiesCS.Test.csproj:76` and `:479` carry exactly one `` each; no duplicate entries (CS2002, issue #394, avoided). | + +## 5. Test Coverage Detail + +All figures below were re-derived by this reviewer directly from the Cobertura documents. No figure +is carried forward from a delivery artifact without independent recomputation. + +### 5.1 Repo-wide, first-party (nine production assemblies) + +| Metric | Baseline | Post-change | Floor | Verdict | +|---|---|---|---|---| +| C# line coverage (pinned `.//line` selection) | 84.50% (112,359/132,967) | 84.51% (112,363/132,961) | 85% uniform | FAIL | +| C# line coverage (deduped cross-check) | 84.65% (55,203/65,214) | 84.66% (55,205/65,211) | 85% uniform | FAIL | +| C# branch coverage (pinned selection) | 79.14% (26,496/33,480) | 79.15% (26,500/33,480) | 75% uniform | PASS | +| C# line coverage against the CLAUDE.md testable-denominator floor | 84.50% | 84.51% | 80% | PASS | + +**Disposition of the line FAIL: NON-BLOCKING.** The shortfall pre-exists on `origin/main` at 84.50% +and this change moves it upward, not downward. The repository carries an unreconciled documentation +conflict — CLAUDE.md states an 80% floor while `.claude/rules/quality-tiers.md` states a uniform 85% +floor — and the figure clears the former and misses the latter. This delivery neither caused the +shortfall nor is scoped to repair it. + +### 5.2 Canonical coverage artifact presence + +| Language | Canonical path | Present | Verdict | +|---|---|---|---| +| C# | `artifacts/csharp/coverage.xml` | No — the `artifacts/csharp/` directory does not exist | FAIL | + +**Reason recorded as required:** coverage artifact absent for C#; coverage verification is mandatory +for all languages with changed files. + +**Disposition: NON-BLOCKING.** Equivalent raw evidence exists at `coverage/782-p0-baseline.cobertura.xml` +and `coverage/782-p7-final.cobertura.xml`, and this reviewer re-derived every repo-wide, per-file, +and changed-line figure from those documents directly rather than accepting a summary. The absence is +a deliberate, documented scope decision (SD1), and the practice has repository precedent. No coverage +question was left unanswerable by the absence. + +### 5.3 New production files + +Zero new production C# files exist on this branch. The two added `*.cs` files, +`UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` and +`UtilitiesCS.Test/Threading/ProgressTracker_ReportAndViewerTests.cs`, are both test-assembly files +and are excluded from the coverage denominator by the derived configuration's +`.*\.Test\.dll$` exclusion. The new-production-file tier therefore has an +empty member set and its 85%/75% thresholds are satisfied vacuously. Verdict: PASS. + +### 5.4 Modified production files + +| File | Baseline line | Post line | Baseline branch | Post branch | Verdict | +|---|---|---|---|---|---| +| `UtilitiesCS/Threading/UiThread.cs` | 77.11% (64/83) | 76.83% (63/82) | 65.00% (13/20) | 65.00% (13/20) | FAIL | +| `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` | 96.43% (27/28) | 100.00% (26/26) | 100.00% (14/14) | 100.00% (14/14) | PASS | +| `UtilitiesCS/Threading/ProgressTracker.cs` | 87.65% (149/170) | 87.65% (149/170) | 82.50% (33/40) | 82.50% (33/40) | PASS | +| `UtilitiesCS/Threading/ProgressTrackerAsync.cs` | 91.49% (43/47) | 91.49% (43/47) | 83.33% (5/6) | 83.33% (5/6) | PASS | +| `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` | not instrumented | not instrumented | not instrumented | not instrumented | PASS | + +`RibbonViewer.EngineCommands.cs` is absent from both Cobertura documents. This reviewer verified the +stated cause rather than accepting it: `TaskMaster/Ribbon/RibbonViewer.cs:32` declares +`[ExcludeFromCodeCoverage]` on the partial type, which suppresses instrumentation for every part. +The file contributes zero executable changed lines, so it cannot regress. + +**Disposition of the `UiThread.cs` FAIL: NON-BLOCKING, with the following measured basis.** + +This reviewer compared the covered and uncovered line sets between the two Cobertura documents rather +than comparing only percentages. The result: + +``` +BASELINE uncovered (19): 28,29,30,32,33,34,67,68,69,70,71,72,73,74,75,76,118,119,120 +POST uncovered (19): 28,29,30,32,33,34,67,68,69,70,71,72,73,74,75,76,118,119,120 +IDENTICAL SETS: True +``` + +Not one line transitioned from covered to uncovered. The uncovered residue is unchanged in both +membership and line number, and sits entirely in members the diff never touched: the `Init` +parameter-handling block (28-34), the `ThreadMonitor` construction inside `Initialize()` (67-76), +which requires a live UI thread, and the lazy `UiSyncContext` accessor (118-120). + +The covered-line delta is 13 baseline-only line numbers against 12 head-only line numbers — pure +renumbering caused by inserting the 18-line XML documentation block, with a net -1 from the wrapped +three-line `throw` collapsing to a single line once routed through the shared constant. Removing a +covered line from a partially covered file necessarily lowers its percentage; that is what produced +the -0.28 point movement, and it is not a coverage regression. + +Against the four-part precedent test for a sub-floor modified file: no changed-line regression +(satisfied, 7/7), residue entirely pre-existing and untouched (satisfied), at or above 80% (**not +satisfied**, 76.83%), improved versus baseline in percentage terms (**not satisfied**, -0.28 points +by denominator arithmetic alone). Because two legs are not satisfied on their face, the FAIL row is +recorded and carried into remediation inputs as a procedural item, with the recommendation that a +maintainer waive it on the byte-identical uncovered-set evidence above. + +### 5.5 Changed-line coverage + +Derived independently by this reviewer: added post-change line numbers were taken from +`git diff -U0` hunk headers and looked up as `` elements in the post-change +Cobertura document. + +| File | Changed executable lines | Covered | Non-executable | +|---|---|---|---| +| `UtilitiesCS/Threading/UiThread.cs` | 4 (159, 160, 166, 168) | 4 | 24 | +| `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` | 1 (65) | 1 | 4 | +| `UtilitiesCS/Threading/ProgressTracker.cs` | 1 (39) | 1 | 0 | +| `UtilitiesCS/Threading/ProgressTrackerAsync.cs` | 1 (39) | 1 | 0 | +| `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` | 0 | 0 | 2 | +| **Total** | **7** | **7** | **30** | + +**Changed-line coverage: 100.00% (7/7).

The -0.28 point movement is the arithmetic consequence of removing one +covered line from a file whose uncovered count is fixed at 19: the covered three-line wrapped +`throw` collapsed to a single line when routed through the shared constant. All 7 changed executable +production lines on the branch are covered. + +The residue sits entirely in members the diff never touched: + +| Lines | Member | Why uncovered | +|---|---|---| +| 28-34 | `Init` parameter handling | pre-existing | +| 67-76 | `ThreadMonitor` construction inside `Initialize()` | requires a live UI thread; constructs and shows a hidden WinForms `SyncContextForm` | +| 118-120 | lazy `UiSyncContext` accessor | pre-existing | + +**Recommended disposition: WAIVE.** Against the four-part precedent test for a sub-floor modified +file: no changed-line regression (satisfied), residue pre-existing and untouched (satisfied), at or +above 80% (not satisfied), improved versus baseline (not satisfied in percentage terms only). The two +unsatisfied legs are both artefacts of the same denominator arithmetic, and the underlying intent of +both — "did any line get worse?" — is satisfied exactly, with proof. + +**If a maintainer prefers remediation instead:** raising `UiThread.cs` above 80% requires covering the +`ThreadMonitor` block at lines 67-76 inside `Initialize()`. That is host-bound WinForms code with UI +thread affinity, and covering it would mean either a seam extraction on production code or a host +harness — both production behaviour changes well outside a Refactor's scope, and the same class of +change this delivery already carved out to issues #787 and #788. **Recommendation: do not remediate +in this branch.** If pursued, promote it as its own entry. + +## R3 — Message constant text is unpinned (Should-fix, non-blocking) + +Carried from code review finding **CR-1**. + +No test asserts the value of `UiThread.DispatcherNotInitializedMessage`. Both message assertions use +the wildcard `WithMessage("*UiThread.Init()*")`, which would still match if the removed tail "before +yielding folder tree work" were restored. `spec.md` AC10 and +`evidence/other/code-review.2026-09-05T23-00.md` entry (b) both state the removal "is pinned by" that +assertion; it is not. + +**Recommended fix (small, low risk).** In `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` +and `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, change the assertion to +`.WithMessage(UiThread.DispatcherNotInitializedMessage)`. The constant is `internal` and +`UtilitiesCS/Properties/AssemblyInfo.cs` grants `InternalsVisibleTo("UtilitiesCS.Test")`, so it is +reachable; the literal contains no `*` or `?`, so it behaves as an exact match. Optionally extend the +same assertion to the two C26 tests, which currently assert only the exception type (finding CR-3). +Then correct the two "pinned by" sentences. + +**Recommended disposition: fix in this branch if convenient, otherwise promote.** It does not block. + +## R4 — Baseline coverage figures not reproducible from the recorded document (Should-fix, non-blocking) + +Carried from code review finding **CR-2 / EV-1**. + +`evidence/baseline/p0-t7-coverage.md` records re-measured baseline figures of 112,355 lines covered +and 26,500 branches covered. Re-aggregating `coverage/782-p0-baseline.cobertura.xml` — the output +path that artifact's own command names — with that artifact's own pinned all-descendant `.//line` +selection yields **112,359 and 26,496**, the values the artifact labels "superseded" and declares +invalid as a baseline side. The file's `CreationTime` and `LastWriteTime` are both +`2026-09-05 19:26:55`, while the artifact carries `Timestamp: 2026-09-05T21-59`. + +**Impact on any verdict: none.** Head reads 112,363 and 26,500. Against either candidate baseline the +conclusion is the same — line coverage improved and branch coverage improved or held. No regression +exists on any reading. + +**Recommended fix.** Amend `evidence/baseline/p0-t7-coverage.md` to state that the re-measurement's +output document was not retained, that the retained document is the 19:26 collection taken at the +re-anchored base `736c2cf2` (committed 19:17, before the first production edit at 20:37), and that it +yields 112,359 / 26,496. Remove the instruction declaring those figures invalid as a baseline side, +since they are the only reproducible ones. Alternatively, re-run the baseline collection so the +document matches the recorded figures. + +**Recommended disposition: amend the artifact.** It does not block. + +## Items explicitly NOT requiring remediation + +| Item | Why not | +|---|---| +| Repo-wide C# line coverage 84.51% below the 85% floor | Pre-exists on `origin/main` at 84.50% and improves.

Correctly open; not a delivery defect. | +| C03 omitted | Discharged through AC2's omission branch with a full measured record, bisect, and mechanism, and promoted as issue #788. This is the correct handling of a withdrawn item. | +| Three `spec.md` passages still describing the C03 re-arm | Already enumerated and disclosed by the delivery's own code-review artifact. Accepted as a recorded decision. | +| Test files in `.Test/` rather than a `tests/` tree | Repository-wide pre-existing convention; not introduced by this branch. | +| Nits CR-4 through CR-7 | Minor test-hygiene observations, several consistent with existing repository precedent. Recorded in the code review; none blocks. | + +## Handoff + +No atomic remediation plan is requested. R1 and R2 are maintainer acceptance decisions rather than +executor work, and R3 and R4 are small optional improvements. If a maintainer elects to act on R3 and +R4, they are a single small task each and do not warrant a phased plan. + +**One action is required before merge, and it is not remediation:** the pull request must close +**only #782**. The seven auto-close candidates in `artifacts/pr_context.summary.txt` (#394, #449, +#476, #493, #508, #584, #778) are prose scrapes from this delivery's own artifacts and must not be +carried into the PR body. From b91dd859b85434ac66c2ae817d7daebf3b0d3342 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sun, 6 Sep 2026 01:58:00 -0400 Subject: [PATCH 24/28] fix(782): correct the message-pinning claim and the baseline coverage input record Addresses findings R3 and R4 of the feature review recorded in remediation-inputs.2026-09-05T23-48.md. Both are Should-fix accuracy defects in this delivery's own audit artifacts; neither blocks the pull request, which the review cleared with PASS and zero blocking findings. R3. spec.md AC10, spec.md AC11, the Behavioral Contract WpfDispatcherYield bullet, the Write Set test-file row, and the code-review entry (b) claimed that the removal of the WpfDispatcherYield message tail was pinned by the C20 WithMessage assertion. It was not: both assertions were the wildcard "*UiThread.Init()*", which also matches the pre-782 message because that message likewise contains UiThread.Init(). Both assertions now read WithMessage(UiThread.DispatcherNotInitializedMessage), which FluentAssertions compares against the entire message, and the prose is corrected to state exactly what that form establishes: a tail appended at a throw site fails the assertion at that site, and neither assertion detects an edit to the constant's own wording. The change is observed rather than derived: appending the removed tail at the WpfDispatcherYield throw site fails YieldAsync_WithoutDispatcher_RemainsStrict while the sibling test still passes, and both pass once the mutation is reverted. R4. evidence/baseline/p0-t7-coverage.md recorded the re-measured first-party figures 112355 and 26500 while naming the earlier collection's output document as its input. The artifact now records both collections with their own inputs and figures, marks the re-measurement authoritative, states that its output document is not retained, and supplies a reproduction procedure. R1 and R2 are accepted and waived respectively, as maintainer decisions following the reviewer's recommendations. No file was changed for either item. The dispositions are recorded in evidence/other/r1-r2-maintainer-disposition.2026-09-06T00-15.md. No production .cs file is changed. Full local toolchain passed in one uninterrupted pass: csharpier format and check (1583 files, exit 0), analyzer build (0 warnings, 0 errors), nullable build (0 warnings, 0 errors), and the nine-assembly run at 7000 passing with 0 failures. Those are locally-filtered figures with the four shell-icon classes excluded, not CI figures.

This plan is therefore **not** a blocking-finding +remediation. + +**R1 and R2 are accepted as recommended and are not acted on.** R1 (the canonical +`artifacts/csharp/coverage.xml` is absent) and R2 (`UiThread.cs` modified-file line coverage at +76.83%, below the 80% trigger floor) are procedural coverage triggers for which the reviewer +recommends maintainer acceptance and waiver respectively. The maintainer has accepted both. No task +in this plan produces `artifacts/csharp/coverage.xml`, and no task changes `UtilitiesCS/Threading/UiThread.cs` +or adds coverage for its `ThreadMonitor` block. The disposition is recorded durably by [P3-T7]. + +**R3 and R4 are fixed even though neither blocks.** Both are accuracy defects in this delivery's own +audit artifacts, and this delivery exists to remove accuracy defects from audit artifacts. Shipping a +new false claim while correcting old ones would be self-refuting. + +### Decision for R3, and the reasoning + +`spec.md` AC10 and `evidence/other/code-review.2026-09-05T23-00.md` entry (b) both state that the +removal of the `WpfDispatcherYield` message tail is pinned by the C20 `WithMessage` assertion. The two +assertions are `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs:136` and +`UtilitiesCS.Test/Threading/UiThread_Tests.cs:142`, both `.WithMessage("*UiThread.Init()*")`. The +pre-782 `WpfDispatcherYield` literal, recorded at `research/research.2026-09-05T16-10.md:102`, was +`"The UI dispatcher has not been captured. Call UiThread.Init() before yielding folder tree work."`, +which also contains `UiThread.Init()`. A wildcard pattern therefore matches both the current message +and the pre-782 message, so the claim is false as written. + +**This plan takes the first of the two options: make the assertion exact by asserting against the +constant, then correct the surrounding prose to state exactly what the exact assertion establishes.** +The reasoning is that this makes the acceptance criterion true rather than making it smaller, and the +cost is two assertion lines. Three facts were re-derived to establish that the change is sound: + +1. `UiThread.DispatcherNotInitializedMessage` is declared `internal const string` at + `UtilitiesCS/Threading/UiThread.cs:135-136`, and `UtilitiesCS/Properties/AssemblyInfo.cs:19` grants + `InternalsVisibleTo("UtilitiesCS.Test")`. Both assertion sites are in `UtilitiesCS.Test`. +2. The constant's value contains no `*` and no `?`. `packages/FluentAssertions.8.10.0/lib/net47/FluentAssertions.xml` + documents `ExceptionAssertions.WithMessage` as taking a pattern that "can contain a combination + of literal text and wildcard (* and ?) characters, but it doesn't support regular expressions", so + a pattern carrying neither wildcard is compared against the whole message. Repository precedent + confirms the wildcard-free form is used and passes: `TaskVisualization.Test/AutoAssignPeopleTests.cs:100` + asserts `WithMessage("seam-invoked")` and `TaskMaster.Test/AppGlobals/AppToDoObjectsTests.cs:416` + asserts a full sentence. +3. Both throw sites pass the constant as the sole message argument — + `UtilitiesCS/Threading/UiThread.cs:166` and `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs:65` + — so the thrown message is byte-identical to the constant and an exact assertion passes. + +**What the exact assertion does and does not pin, stated precisely because the corrected prose must +say it.** It pins that the message surfaced at each site is the shared constant verbatim, so +re-introducing a caller-specific tail at a throw site fails the assertion **at that site** — the +assertion in `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` for the +`WpfDispatcherYield` throw, and the assertion in `UtilitiesCS.Test/Threading/UiThread_Tests.cs` for +the `UiThread.Dispatcher` throw. The C20 test injects two null providers, so it reaches the +`WpfDispatcherYield` throw only and a tail appended at the other site does not fail it. Neither +assertion pins the constant's own literal text, because an assertion written against the constant +moves with the constant. One part of that wording is nonetheless held by a test: +`UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs:196` asserts +`Message.Should().Contain("UiThread.Init()")`, so an edit removing that substring from the constant +fails that test. The corrected AC10 and code-review text must state the first, disclaim the second, +and record the third. Claiming more than that would reproduce R3 in a new form. + +**Falsification.** A claim about a test assertion is not accepted here on reading alone. [P1-T5] +through [P1-T9] temporarily append the removed tail at the `WpfDispatcherYield` throw site, build, +observe `YieldAsync_WithoutDispatcher_RemainsStrict` fail while +`Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` still passes, +then revert and observe both pass. That sequence is the check that would detect the claim being +false. + +### Decision for R4, and the reasoning + +`evidence/baseline/p0-t7-coverage.md` records baseline first-party figures of 112355 lines covered and +26500 branches covered, and its recorded command names `coverage\782-p0-baseline.cobertura.xml` as its +`--output`. Re-aggregating that on-disk document yields 112359 and 26496 — the values the artifact +labels superseded and declares invalid as a baseline side. The artifact carries +`Timestamp: 2026-09-05T21-59` while the named file was last written at `2026-09-05 19:26:55`. + +**This plan takes the combined option: record both collections with their own inputs and figures, +keep the re-measured figures authoritative on substance, state explicitly that the authoritative +collection's output document is not present in this worktree and is treated as not retained, and +supply a reproduction procedure.** The reasoning: + +- The re-measured figures 112355 / 26500 were taken at the re-anchored base `736c2cf2`, which is this + branch's actual baseline. They are the correct baseline on substance. Promoting the retained + document's 112359 / 26496 to authoritative would resurrect a measurement of an orphaned tree and + would contradict `evidence/qa-gates/p7-t7-changed-line-coverage.md:99`, which records that neither + superseded figure is used. That would fix one inconsistency by creating another. +- Re-running the baseline collection so a document matches the recorded figures is rejected. It would + require restoring six Write Set files to `pre-782-base` content in the delivered worktree for the + duration of a collection run, and its result would be a third measurement rather than a + confirmation of the second. The recorded figures would remain unreproducible from any retained + document either way, and `coverage/` is git-ignored, so even a fresh document would not become + committed evidence. +- The reconciling observation is that the retained document is the earlier collection's output, not + the re-measurement's. Its companion log `coverage/782-p0-cov.txt` records `Total tests: 6992`, the + superseded-base count, against the `6997` the re-anchored run recorded at + `evidence/baseline/p0-t6-vstest.md:71`; that discriminator is independent of file timestamps. The + recorded `--output` argument is relative, so the recorded command run from this worktree root would + have overwritten the retained document and did not. The record does not establish how the + re-measurement's invocation differed, and the amended artifact says so rather than supplying a + mechanism it cannot evidence. +- The retained document is not deleted from the record and its figures are not suppressed. The + amended artifact states what it is, what it yields, and how to reproduce that, so a reader who + aggregates it is not contradicted by the artifact. + +`coverage/` is matched by `.gitignore:144` (`coverage/*`, with only `coverage/.gitkeep` re-included), +so no document under it can be cited as committed evidence. The amended artifact states that +constraint explicitly rather than implying the input is part of the delivery. + +## Scope boundary + +**In scope.** Two assertion lines in two `UtilitiesCS.Test` files; five claim sites in `spec.md`, the +fifth being the Write Set test-file table row for `UtilitiesCS.Test/Threading/UiThread_Tests.cs`; one +entry in `evidence/other/code-review.2026-09-05T23-00.md`; two rows in +`evidence/other/ac-status-summary.2026-09-05T23-15.md`; the amendment of +`evidence/baseline/p0-t7-coverage.md`; new evidence artifacts under this feature's `evidence/` subtree; +this plan file. + +The acceptance-criteria sources for this work mode are `spec.md` and `user-story.md`. `user-story.md` +is not edited.

The dotnet local-tool manifest is `dotnet-tools.json` at the repository root and pins CSharpier + 1.2.6. `dotnet tool restore` has already been run; no task re-runs it. CSharpier 1.2.6 requires a + subcommand, so `format` and `check` are always written explicitly. +3. `msbuild` resolves to the Visual Studio 18 Community MSBuild. `packages/` is restored and no + analyzer-version skew exists on this branch. +4. `dotnet-coverage` 18.10.0 is installed globally and is invoked by its bare name. +5. `vstest.console.exe` is resolved through vswhere: + + ```powershell + $vswhere = "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" + $vstest = & $vswhere -latest -products * -find Common7\IDE\Extensions\TestPlatform\vstest.console.exe | + Select-Object -First 1 + ``` + +6. **Semicolon-bearing switches must be single-quoted.** PowerShell treats `;` as a statement + separator, so `/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None` and any + `/flp:LogFile=...;Verbosity=normal` are truncated at the first semicolon when written bare.

Each file +already resolves a type by the same outward walk — `UiThread.SynchronizationContextAwaiter` at +`UiThread_Tests.cs:16` and `UiThreadDispatcherScope` at `WpfDispatcherYieldTests.cs:167`. A `using` +directive is added **only if** the [P1-T3] build reports `CS0103` or `CS0246` naming `UiThread` in +that file, and then only `using UtilitiesCS;`. + +The single-line token later tasks assert is `WithMessage(UiThread.DispatcherNotInitializedMessage)`. +At the deeper of the two indentations above — the 20-space chained-call indent in `UiThread_Tests.cs` +— the token ends at column 74, and at the 16-space indent in `WpfDispatcherYieldTests.cs` it ends at +column 70.

What is binding is that each token an +acceptance condition asserts stays whole on a single line in the written file.

Acceptance: the artifact exists, its `Policy Order:` line names all six paths, and it carries six line-count bullets. These files are read only; no task in this plan writes under `.claude/`. +- [x] [P0-T2] Write `evidence/remediation-baseline/r-p0-t2-claim-inventory.md` recording, for each of the eight claim sites this plan changes, the file path, the current line range, and the current text quoted verbatim: `spec.md` AC10, `spec.md` AC11, `spec.md` Behavioral Contract `WpfDispatcherYield` bullet, `spec.md` Write Set test-file table row for `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, `evidence/other/code-review.2026-09-05T23-00.md` entry (b), `evidence/other/ac-status-summary.2026-09-05T23-15.md` AC10 row, `evidence/other/ac-status-summary.2026-09-05T23-15.md` AC11 row, and `evidence/baseline/p0-t7-coverage.md` superseded-figures section. The same artifact additionally records, as three labelled counts with their matching line numbers, the output of `Select-String -SimpleMatch 'is pinned by'`, of `Select-String -SimpleMatch '*UiThread.Init()*'`, and of `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)'`, each run over `docs\features\active\2026-09-05-pr-778-post-merge-review-residuals-782\spec.md` alone, and a fourth labelled count with its matching line number for `Select-String -SimpleMatch 'would fail that test'` run over `docs\features\active\2026-09-05-pr-778-post-merge-review-residuals-782\evidence\other\code-review.2026-09-05T23-00.md` alone. Acceptance: the artifact contains exactly eight quoted current-text blocks, each preceded by its `path:line-range` header, and carries the four labelled counts with their line numbers. The line ranges and the four counts are re-derived by `Select-String` in this task, not copied from this plan. [P2-T4], [P2-T5], and [P2-T8] read their stated before-counts from this artifact. +- [x] [P0-T3] Run `Select-String -SimpleMatch 'WithMessage("*UiThread.Init()*")' -Path 'UtilitiesCS.Test\Threading\UiThread_Tests.cs','UtilitiesCS.Test\OutlookObjects\Folder\WpfDispatcherYieldTests.cs'` and `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)' -Path` the same two files, and record both outputs in `evidence/remediation-baseline/r-p0-t3-assertion-sites.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Acceptance: the first search reports exactly 2 matching lines, one per file; the second reports 0. Those two counts are the before state that [P1-T10] inverts. +- [x] [P0-T4] Run `git show pre-782-base:UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` and record, in `evidence/remediation-baseline/r-p0-t4-pre782-message.md`, the pre-782 `InvalidOperationException` message literal quoted verbatim together with its line number in that revision, plus the current literal at `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs:65`. Acceptance: the artifact quotes a pre-782 literal that contains both the substring `UiThread.Init()` and the substring `before yielding folder tree work`, and quotes a current line that contains `UiThread.DispatcherNotInitializedMessage`. That pairing is the evidence that a wildcard on `UiThread.Init()` cannot distinguish the two messages. +- [x] [P0-T5] Aggregate `coverage\782-p0-baseline.cobertura.xml` with the pinned aggregation snippet in this plan's "The pinned coverage aggregation" section and record the printed `LINES_COVERED=... LINES_VALID=... BRANCHES_COVERED=... BRANCHES_VALID=...` line verbatim in `evidence/remediation-baseline/r-p0-t5-retained-cobertura-reaggregation.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Acceptance: the artifact records `LINES_COVERED=112359` and `BRANCHES_COVERED=26496`. If either differs, the task is left unchecked and the observed values are recorded, because Phase 3's amendment text depends on these two figures being the ones a reader obtains from that document. +- [x] [P0-T6] Record the retained document's provenance in `evidence/remediation-baseline/r-p0-t6-retained-document-provenance.md`: the `CreationTime` and `LastWriteTime` of `coverage\782-p0-baseline.cobertura.xml` and of `coverage\782-p0-cov.txt` from `Get-Item`, the single line matching `Select-String -SimpleMatch 'Total tests:' -Path 'coverage\782-p0-cov.txt'`, and the output of `git check-ignore -v -- coverage/782-p0-baseline.cobertura.xml`. Acceptance: the artifact records a `Total tests:` figure from `coverage\782-p0-cov.txt`, records both files' timestamps, and records a non-empty `git check-ignore -v` line naming `.gitignore`. The artifact states which of the two recorded baseline test counts — the superseded 6992 or the re-anchored 6997 — the retained collection's log matches, and states that this is the discriminating observation for which collection wrote that document. +- [x] [P0-T7] Run the SDK preamble then `dotnet tool run csharpier check .` from the worktree root and write `evidence/remediation-baseline/r-p0-t7-csharpier-check.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` recording the printed `Checked files` line verbatim. Acceptance: `EXIT_CODE: 0` and the artifact records a `Checked` line carrying a numeral. That numeral is the comparison value [P4-T2] asserts against. +- [x] [P0-T8] Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` and write `evidence/remediation-baseline/r-p0-t8-analyzer-build.md` with the four required fields, recording the final ` Warning(s)` and ` Error(s)` lines verbatim. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`. +- [x] [P0-T9] Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true` and write `evidence/remediation-baseline/r-p0-t9-nullable-build.md` with the four required fields, recording the final ` Warning(s)` and ` Error(s)` lines verbatim. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`. `/p:Nullable=enable` is not passed and `/t:Build` is not substituted. +- [x] [P0-T10] Regenerate the derived coverage configuration, then run `dotnet-coverage collect --output coverage\782-r1-baseline.cobertura.xml --output-format cobertura --settings coverage\782-effective-coverage.config -- $vstest '/Settings:scripts\vscode\TaskMaster.cli.runsettings' '/InIsolation' '/Logger:trx' '/ResultsDirectory:TestResults\782-r1-baseline' '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None' '/TestCaseFilter:TestCategory!=LiveOutlook&FullyQualifiedName!~HelperClasses.ShellUtilities_Tests&FullyQualifiedName!~HelperClasses.ShellUtilitiesStatic_Tests&FullyQualifiedName!~HelperClasses.SysImageListHelperTests&FullyQualifiedName!~EmailIntelligence.OSBrowser_Tests'`, then aggregate the written document with the pinned snippet. Write `evidence/remediation-baseline/r-p0-t10-tests-coverage.md` with `Timestamp:`, `Command:` recording the quoted form of every semicolon-bearing switch, `EXIT_CODE:`, and `Output Summary:` carrying `Total tests`, `Passed`, `Failed` read from the TRX `ResultSummary/Counters` element, the four aggregated first-party counters as `BASELINE-LINES-COVERED:`, `BASELINE-LINES-VALID:`, `BASELINE-BRANCHES-COVERED:`, `BASELINE-BRANCHES-VALID:` on their own lines, and the statement that these are locally-filtered figures and not CI figures. Acceptance: `EXIT_CODE: 0`, `Total tests: 7000`, `Passed: 7000`, `Failed: 0`, and four numeric counter lines present. The artifact also records that `coverage\782-r1-baseline.cobertura.xml` is git-ignored and is a local artifact, and gives the aggregation command by which a reader reproduces the four counters from it. +- [x] [P0-T11] Run `git rev-parse pre-782-base` and `git rev-parse HEAD` and write `evidence/remediation-baseline/r-p0-t11-anchor.md` recording both, with the HEAD value on its own line as `REMEDIATION-BASE-SHA: `. Acceptance: the recorded `pre-782-base` value begins `736c2cf2`, and the artifact carries exactly one `REMEDIATION-BASE-SHA:` line. Later tasks read the base SHA from this line rather than from any value tabled in this plan. +- [x] [P0-T12] Run `git status --porcelain --untracked-files=all -- .claude` and `git diff --name-only pre-782-base..HEAD -- .claude` and write `evidence/remediation-baseline/r-p0-t12-dotclaude-baseline.md` recording both commands and their line counts as `PORCELAIN_LINES=` and `DIFF_LINES=`. Acceptance: both recorded line counts are `0`. If either is non-zero the task is left unchecked and the offending paths are recorded, because this plan may not proceed while a pre-existing `.claude/` residue would be attributed to it. + +### Phase 1 — R3 Implementation and Falsification of the Pinning Claim + +- [x] [P1-T1] In `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, replace the assertion at line 142 with the three-line form given under "R3-A" in this plan. Acceptance: `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)' -Path 'UtilitiesCS.Test\Threading\UiThread_Tests.cs'` reports exactly 1 matching line, and `Select-String -SimpleMatch 'WithMessage("*UiThread.Init()*")'` on the same file reports 0. The test method name `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` is unchanged; a rename is prohibited by SD4. +- [x] [P1-T2] In `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`, replace the trailing `.WithMessage("*UiThread.Init()*");` at line 136 with the one-line form given under "R3-A". Acceptance: `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)' -Path 'UtilitiesCS.Test\OutlookObjects\Folder\WpfDispatcherYieldTests.cs'` reports exactly 1 matching line, and `Select-String -SimpleMatch 'WithMessage("*UiThread.Init()*")'` on the same file reports 0. The `Message.Should().Contain("UiThread.Init()")` assertion at line 196 is not changed: it belongs to the production-fallback test, which exercises the `UiThread.Dispatcher` throw rather than the `WpfDispatcherYield` guard. +- [x] [P1-T3] Run the analyzer msbuild command from [P0-T8] and write `evidence/qa-gates/r-p1-t3-analyzer-build.md` with the four required fields. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`. If the build reports `CS0103` or `CS0246` naming `UiThread` in either edited file, add `using UtilitiesCS;` to that file, re-run this command, and record both runs in the same artifact; the acceptance is decided by the final run. +- [x] [P1-T4] Run `& $vstest UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll '/Settings:scripts\vscode\TaskMaster.cli.runsettings' '/InIsolation' '/Logger:trx' '/ResultsDirectory:TestResults\782-r1-p1t4' '/Blame:CollectHangDump;TestTimeout=5min;HangDumpType=None' '/TestCaseFilter:FullyQualifiedName~YieldAsync_WithoutDispatcher_RemainsStrict|FullyQualifiedName~Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize'` and write `evidence/qa-gates/r-p1-t4-assertion-tests.md` with the four required fields. Acceptance: `EXIT_CODE: 0`, `Total tests: 2`, `Passed: 2`, `Failed: 0`, and the `Output Summary:` names both fully-qualified test identifiers. `Total tests: 2` is asserted rather than `Passed: 2` alone so an over-broad filter is visible. +- [x] [P1-T5] Apply the temporary falsification mutation: in `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`, change the throw at line 65 to `throw new InvalidOperationException(UiThread.DispatcherNotInitializedMessage + " before yielding folder tree work");`. Write `evidence/regression-testing/r-p1-t5-mutation-applied.md` recording the exact before and after text of that line and the statement that the mutation is temporary and is reverted by [P1-T8]. Acceptance: `Select-String -SimpleMatch 'before yielding folder tree work' -Path 'UtilitiesCS\OutlookObjects\Folder\WpfDispatcherYield.cs'` reports exactly 1 matching line, and `git status --porcelain -- UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` reports exactly 1 line. No CSharpier run occurs while the mutation is in place. +- [x] [P1-T6] Run the analyzer msbuild command from [P0-T8] with the mutation in place and write `evidence/regression-testing/r-p1-t6-mutation-build.md` with the four required fields. Acceptance: `EXIT_CODE: 0`. A failing build here means the falsification cannot be demonstrated and the task is left unchecked. +- [x] [P1-T7] [expect-fail] Re-run the [P1-T4] command with `'/ResultsDirectory:TestResults\782-r1-p1t7'` and write `evidence/regression-testing/r-p1-t7-fail-before.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `ExpectedExitCode: 1`, and `Output Summary:`. Acceptance: `EXIT_CODE: 1`, `Total tests: 2`, `Passed: 1`, `Failed: 1`, the failing test is `UtilitiesCS.Test.OutlookObjects.Folder.WpfDispatcherYieldTests.YieldAsync_WithoutDispatcher_RemainsStrict`, and the passing test is `UtilitiesCS.Test.Threading.UiThread_Dispatcher_Tests.Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`. The artifact also records the FluentAssertions failure message verbatim. This is the observation that would detect the R3 pinning claim being false: no run of this mutation against the previous wildcard assertion was performed; by derivation it would not have failed, because the mutated message still contains `UiThread.Init()`, which `*UiThread.Init()*` matches. The artifact states that this leg is derived and not observed. +- [x] [P1-T8] Revert the mutation with `git checkout -- UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs`, re-run the analyzer msbuild command from [P0-T8], and write `evidence/regression-testing/r-p1-t8-mutation-reverted.md` with the four required fields. Acceptance: `git status --porcelain -- UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` reports 0 lines; `git diff --name-only HEAD -- UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` reports 0 lines; `Select-String -SimpleMatch 'before yielding folder tree work' -Path 'UtilitiesCS\OutlookObjects\Folder\WpfDispatcherYield.cs'` reports 0 matching lines; and the msbuild `EXIT_CODE:` is `0`. All four are recorded in the artifact. +- [x] [P1-T9] Re-run the [P1-T4] command with `'/ResultsDirectory:TestResults\782-r1-p1t9'` and write `evidence/regression-testing/r-p1-t9-pass-after.md` with the four required fields. Acceptance: `EXIT_CODE: 0`, `Total tests: 2`, `Passed: 2`, `Failed: 0`. Together with [P1-T7] this establishes that the assertion distinguishes the delivered message from a tail-restored one. +- [x] [P1-T10] Write `evidence/qa-gates/r-p1-t10-assertion-token-gate.md` recording the output and match counts of `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)' -Path 'UtilitiesCS.Test\Threading\UiThread_Tests.cs','UtilitiesCS.Test\OutlookObjects\Folder\WpfDispatcherYieldTests.cs'` and of `Select-String -SimpleMatch 'WithMessage("*UiThread.Init()*")' -Path` the same two files, with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Acceptance: the first search reports exactly 2 matching lines, one in each file; the second reports 0. The artifact states the before counts from [P0-T3] alongside the after counts so the inversion is visible in one place. The search is scoped to those two files because `"*UiThread.Init()*"` legitimately survives in `spec.md`, in the reviewer's artifacts, and in `evidence/qa-gates/p1-t9-phase1-tests.md`, none of which this task asserts over. + +### Phase 2 — R3 Claim Correction in the Specification and the Code-Review Artifact + +**Wrap discipline, binding on every task in this phase and in Phase 3.** Each acceptance condition +below asserts a short literal token. When the executor wraps the surrounding prose to the file's +existing column width, it must keep each asserted token whole on one line. A token broken across a +wrap makes its own acceptance condition fail, which halts the task rather than passing it silently; +the remedy is to move the wrap point, never to weaken the condition. + +- [x] [P2-T1] Replace the AC10 pinning clause in `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/spec.md` with the text given under "R3-B", and extend AC10's **Evidence:** sentence with the clause given there. Acceptance: `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)' -Path spec.md` reports at least 1 matching line inside the AC10 entry; the AC10 entry contains the single-line token `moves with the constant`; and the AC10 entry contains the single-line token `evidence/regression-testing/`. AC10's checkbox state remains `[x]`. +- [x] [P2-T2] Replace the two AC11 clauses in `spec.md` with the texts given under "R3-C". Acceptance: the AC11 entry contains `WithMessage(UiThread.DispatcherNotInitializedMessage)` on a matching line, contains the unchanged method name `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize`, and no longer contains `*UiThread.Init()*` anywhere within its entry. AC11's checkbox state remains `[x]`. +- [x] [P2-T3] Replace the Behavioral Contract `WpfDispatcherYield` bullet in `spec.md` with the text given under "R3-D", leaving the two bounding facts that follow it in the same bullet unchanged. Acceptance: the bullet contains the single-line token `AC10 records it`, and the two bounding clauses beginning `the guard is` and `the guard therefore covers only injected` are both still present. +- [x] [P2-T4] Run `Select-String -SimpleMatch 'is pinned by' -Path 'docs\features\active\2026-09-05-pr-778-post-merge-review-residuals-782\spec.md'` and record the result in `evidence/qa-gates/r-p2-t4-spec-claim-gate.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Acceptance: the search reports 0 matching lines, and the same artifact records that `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)'` over the same file reports at least 2 matching lines. Both counts are recorded, because a zero-hit search alone can pass vacuously if the phrase merely re-wrapped, whereas the positive count cannot be satisfied without the intended edit. The [P0-T2] inventory records that `is pinned by` occurred exactly twice in `spec.md` before this phase, at the two sites [P2-T1] and [P2-T3] rewrite; the SD5 scope-decision row's `pinned by AC10` wording is a different token and is deliberately retained, because AC10 is now true. +- [x] [P2-T5] Replace the sentence identified under "R3-E" in `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/other/code-review.2026-09-05T23-00.md` entry (b) with the replacement text given there. Acceptance: entry (b) contains `WithMessage(UiThread.DispatcherNotInitializedMessage)` on a matching line, contains the single-line token `moves with the constant`, and contains the single-line token `did not have that property`; and `Select-String -SimpleMatch 'would fail that test'` over `evidence/other/code-review.2026-09-05T23-00.md` reports 0 matching lines, that clause being the false claim this task removes and appearing in no replacement text this plan supplies. The entry retains its existing first two sentences describing SD5 and the domain-neutral constant. [P0-T2] records that `would fail that test` occurred exactly once in that file before this phase, inside the sentence this task replaces. +- [x] [P2-T6] Replace the AC10 row justification in `evidence/other/ac-status-summary.2026-09-05T23-15.md` so it states that `YieldAsync_WithoutDispatcher_RemainsStrict` asserts the whole message against the shared constant and recorded `Passed`, and cites the falsification record under `evidence/regression-testing/`. Acceptance: the AC10 row contains `WithMessage(UiThread.DispatcherNotInitializedMessage)` and contains `r-p1-t7-fail-before.md`; its status cell remains `` `[x]` ``. +- [x] [P2-T7] Replace the AC11 row justification in `evidence/other/ac-status-summary.2026-09-05T23-15.md` so it states that the test method retains its exact name and asserts the shared constant. Acceptance: the AC11 row contains `WithMessage(UiThread.DispatcherNotInitializedMessage)`, contains the unchanged method name, no longer contains `*UiThread.Init()*`, and its status cell remains `` `[x]` ``. +- [x] [P2-T8] In `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/spec.md`, in the "Write Set — test files" table row whose first cell is `` `UtilitiesCS.Test/Threading/UiThread_Tests.cs` ``, replace the clause ``assert `*UiThread.Init()*` `` with ``assert the shared constant through `WithMessage(UiThread.DispatcherNotInitializedMessage)` ``, leaving the rest of that row and its Findings cell unchanged. Write `evidence/qa-gates/r-p2-t8-spec-wildcard-gate.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Acceptance: `Select-String -SimpleMatch '*UiThread.Init()*' -Path 'docs\features\active\2026-09-05-pr-778-post-merge-review-residuals-782\spec.md'` reports 0 matching lines, and `Select-String -SimpleMatch 'WithMessage(UiThread.DispatcherNotInitializedMessage)'` over the same file reports at least 4 matching lines; both counts are recorded in the artifact. The [P0-T2] inventory records that `*UiThread.Init()*` occurred exactly three times in `spec.md` before Phase 2, at lines 193, 657, and 661, all three of which Phase 2 rewrites: [P2-T2] rewrites the two AC11 occurrences and this task rewrites the Write Set row. The four expected `WithMessage(UiThread.DispatcherNotInitializedMessage)` lines are the one [P2-T1] writes into AC10, the two [P2-T2] writes into AC11, and the one this task writes into the Write Set row. + +### Phase 3 — R4 Baseline Coverage Artifact Amendment and Recorded Dispositions + +Every edit in this phase is to `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/baseline/p0-t7-coverage.md` unless another path is named. The artifact retains exactly one line-start `Timestamp:`, one line-start `Command:`, and one line-start `EXIT_CODE:` throughout; every additional command shown by this phase is introduced by prose and placed inside a fenced block, never as a bare field at column 0. + +- [x] [P3-T1] Insert an `Amended: 2026-09-06T00-15` line immediately after the existing `Timestamp: 2026-09-05T21-59` line, followed by a one-paragraph amendment note stating that the amendment corrects the identification of this artifact's input document and does not change any recorded figure. Acceptance: the file carries exactly one line beginning `Timestamp:` and exactly one line beginning `Amended:`, and the paragraph contains the single-line token `does not change any recorded figure`. +- [x] [P3-T2] Immediately below the existing fenced command block, add a note stating: that `--output coverage\782-p0-baseline.cobertura.xml` is a relative path, so run from this worktree root the recorded command would have written or overwritten `coverage/782-p0-baseline.cobertura.xml` in this worktree; that it did not, because [P0-T6] records that file's last write time as preceding this artifact's `Timestamp:` and records its companion log `coverage/782-p0-cov.txt` carrying `Total tests: 6992` rather than the `6997` recorded at `evidence/baseline/p0-t6-vstest.md:71`; that the retained document is therefore the earlier, superseded collection's output rather than the re-measurement's; and that the re-measurement's own output document is not present in this worktree and is treated as not retained, the reason for its absence not being established by any record this artifact can cite. Acceptance: the note contains the single-line tokens `is a relative path`, `is treated as not retained`, and `782-p0-cov.txt`; it carries both numerals `6992` and `6997`; `Select-String -SimpleMatch 'outside this repository'` over the file reports 0 matching lines; and the fenced command block above it is byte-unchanged. That zero-hit clause is a guard against reintroducing a mechanism the record refutes rather than a discriminating count: the phrase is absent from the file before this task, and the three positive tokens are what distinguish a written note from an unwritten one. +- [x] [P3-T3] Replace the section headed `### Superseded first-party figures, retained for audit and not current` with a section headed `### The two baseline collections, their inputs, and which is authoritative`, containing: the fenced `text` block of six keys given under "R4" in this plan; a table with one row per collection giving its base commit as the artifact records it, its lines-covered and branches-covered figures, its output document or `NOT RETAINED`, and whether the figures are reproducible from a document available today; and the statement that the re-measured figures are authoritative as this branch's baseline because they were taken at the re-anchored base `736c2cf2`, while the retained document's figures were taken at the orphaned base the head of this artifact names; and, retained verbatim as the last line of the new section, the existing sentence "A Phase 7 comparison that reads either 112359 or 26496 as its baseline side is invalid.", which [P3-T4] then rewrites in place. Acceptance: `Select-String -SimpleMatch '### Superseded first-party figures, retained for audit and not current'` over the file reports 0 matching lines; all six keys from "R4" are present, each on its own matching line; and the retained-document row records `112359` and `26496`; and `Select-String -SimpleMatch 'baseline side is invalid'` over the file still reports exactly 1 matching line at the end of this task, so [P3-T4]'s zero-hit gate has something to remove. A heading is used as the negative token because a Markdown heading cannot survive a line wrap. The retained sentence is written on one line so that token is not split. +- [x] [P3-T4] Replace the sentence declaring that a Phase 7 comparison reading 112359 or 26496 as its baseline side is invalid with a statement that those two figures are the orphaned-base measurement, that they are correctly not used as this branch's baseline side, that `evidence/qa-gates/p7-t7-changed-line-coverage.md` records that they are not used, and that they are nonetheless the figures a reader obtains from the retained document and are recorded here for that reason. Acceptance: `Select-String -SimpleMatch 'baseline side is invalid'` over the file reports 0 matching lines; the replacement text contains the single-line tokens `orphaned-base measurement` and `p7-t7-changed-line-coverage.md`; and both `112359` and `26496` still appear in the file. +- [x] [P3-T5] Replace the `### Test run` section so each test count is attached to its own collection: state which recorded count the retained collection's companion log `coverage/782-p0-cov.txt` carries, as measured by [P0-T6], and state that the re-anchored re-measurement corresponds to the 6997 figure recorded in `evidence/baseline/p0-t6-vstest.md`. Acceptance: the section names both `coverage/782-p0-cov.txt` and `evidence/baseline/p0-t6-vstest.md`, carries both numerals `6992` and `6997`, and restates that both are locally-filtered figures and not CI figures. +- [x] [P3-T6] Add a final section headed `### Reproducing these figures` containing: a statement that `coverage/` is git-ignored by `.gitignore` and that no document under it is committed evidence; the pinned aggregation snippet from this plan, by which a reader reproduces `112359` and `26496` from the retained document; and the procedure by which the authoritative figures would be reproduced — restore the six Write Set files to `pre-782-base` content, run the recorded collect command from the worktree root, then aggregate — together with the statement that this plan does not perform that run because it would mutate the delivered worktree and would yield a new third measurement rather than confirm the recorded one. Acceptance: the section contains the single-line tokens `git-ignored`, `is not committed evidence`, and `a new third measurement`, and contains a fenced `powershell` block carrying the string `SelectNodes('.//line')`. +- [x] [P3-T7] Write `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/other/r1-r2-maintainer-disposition.2026-09-06T00-15.md` recording, with `Timestamp:`: that the feature review returned PASS with zero blocking findings; that R1 is accepted with no remediation, quoting the reviewer's grounds and recording that `artifacts/csharp/coverage.xml` is deliberately not produced under scope decision SD1; that R2 is waived, quoting the reviewer's identical-uncovered-line-set measurement and recording that raising `UiThread.cs` above the 80% trigger floor would require covering the host-bound `ThreadMonitor` block and is promoted rather than performed here; and that no file was changed for either item. Acceptance: the artifact names both `R1` and `R2`, contains the single-line tokens `ACCEPT, no remediation` and `WAIVE`, contains the token `artifacts/csharp/coverage.xml`, and states that no file was changed for either item; and the artifact records the reviewer's stated qualification that the "would force a FAIL verdict" rationale for SD1 is not a legitimate reason to omit the artifact, that the reviewer recorded the FAIL regardless, and that the acceptance rests on the substitute raw evidence rather than on that rationale. That qualification is at `remediation-inputs.2026-09-05T23-48.md:47-51`. + +### Phase 4 — Final QC: the full C# toolchain in order + +The four toolchain steps run in order — format, then check, then the analyzer build, then the nullable +build, then the coverage-bearing test run. **If any step fails or changes a file, the loop restarts at +[P4-T1]** and every artifact from the restarted pass is rewritten. The phase is complete only when all +five command tasks pass in one uninterrupted pass. `EXIT_CODE: SKIPPED` is not a passing outcome for +any task in this phase. + +- [x] [P4-T1] Capture `git status --porcelain --untracked-files=all` to a variable, run the SDK preamble then `dotnet tool run csharpier format .`, then capture `git status --porcelain --untracked-files=all` again. Write `evidence/qa-gates/r-p4-t1-format.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` recording the printed `Formatted files` line verbatim and both porcelain captures in full. Acceptance: `EXIT_CODE: 0` and the set of paths in the two porcelain captures is identical; and the `git diff --no-index`-free content check is satisfied by recording `git diff --stat HEAD` before and after the format run and asserting the two are identical, which detects a rewrite of a file that was already modified and that the path-set comparison alone cannot see. The path-set comparison is the observation that distinguishes a clean run from a repairing one for a file that was previously unmodified; the printed `Formatted` numeral is a processed count rather than a changed count and is recorded but not asserted against. Both `git diff --stat HEAD` outputs are recorded in the artifact in full. +- [x] [P4-T2] Run the SDK preamble then `dotnet tool run csharpier check .` and write `evidence/qa-gates/r-p4-t2-format-check.md` with the four required fields, recording the printed `Checked files` line verbatim. Acceptance: `EXIT_CODE: 0` and the recorded numeral equals the numeral recorded by [P0-T7]. A different numeral means the tracked file set changed and must be explained in the artifact before the task is checked. +- [x] [P4-T3] Run the analyzer msbuild command from [P0-T8] and write `evidence/qa-gates/r-p4-t3-analyzer-build.md` with the four required fields. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`. +- [x] [P4-T4] Run the nullable msbuild command from [P0-T9] and write `evidence/qa-gates/r-p4-t4-nullable-build.md` with the four required fields. Acceptance: `EXIT_CODE: 0`, `0 Warning(s)`, `0 Error(s)`. `/p:Nullable=enable` is not passed and `/t:Build` is not substituted. +- [x] [P4-T5] Regenerate the derived coverage configuration, then run the [P0-T10] collect command with `--output coverage\782-r1-final.cobertura.xml` and `'/ResultsDirectory:TestResults\782-r1-final'`, then aggregate the written document with the pinned snippet. Write `evidence/qa-gates/r-p4-t5-tests-coverage.md` with `Timestamp:`, `Command:` recording the quoted form of every semicolon-bearing switch, `EXIT_CODE:`, and `Output Summary:` carrying `Total tests`, `Passed`, `Failed` from the TRX `ResultSummary/Counters` element and the four aggregated first-party counters as `FINAL-LINES-COVERED:`, `FINAL-LINES-VALID:`, `FINAL-BRANCHES-COVERED:`, `FINAL-BRANCHES-VALID:` on their own lines. Acceptance: `EXIT_CODE: 0`, `Total tests: 7000`, `Passed: 7000`, `Failed: 0`, four numeric counter lines present, and the artifact states that these are locally-filtered figures and not CI figures. +- [x] [P4-T6] Write `evidence/qa-gates/r-p4-t6-coverage-comparison.md` comparing the [P4-T5] counters against the [P0-T10] counters read from those artifacts' own key lines, and enumerating this remediation's changed C# files with `git status --porcelain --untracked-files=all -- '*.cs'`. Acceptance: `FINAL-LINES-VALID` equals `BASELINE-LINES-VALID` and `FINAL-BRANCHES-VALID` equals `BASELINE-BRANCHES-VALID`, so the two sides are comparable; `FINAL-LINES-COVERED` is greater than or equal to `BASELINE-LINES-COVERED`; `FINAL-BRANCHES-COVERED` is greater than or equal to `BASELINE-BRANCHES-COVERED`; and the porcelain enumeration lists exactly `UtilitiesCS.Test/Threading/UiThread_Tests.cs` and `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` and no other `.cs` path. The artifact records that no production `.cs` file is changed by this remediation, that changed-line coverage is therefore NOT APPLICABLE for it, and that both changed files are test files excluded from the coverage denominator by the derived configuration's `.*\.Test\.dll$` module exclusion. If a denominator differs between the two sides, the artifact records the line and branch percentages for both sides and the comparison is made on those percentages instead, with the reason stated. +- [x] [P4-T7] Write `evidence/qa-gates/r-p4-t7-loop-closure.md` recording, for each of [P4-T1] through [P4-T6], the artifact path, the command, and the exit code, and stating whether the pass was uninterrupted or the loop restarted. Acceptance: the artifact lists all six tasks, every recorded exit code is `0`, no entry records `SKIPPED`, and the artifact states the pass number and that all steps completed in one pass. + +### Phase 5 — Commit and Closure + +- [x] [P5-T1] Run `git status --porcelain --untracked-files=all -- .claude` and `git diff --name-only pre-782-base..HEAD -- .claude` and write `evidence/qa-gates/r-p5-t1-dotclaude-untouched.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` recording both outputs and their line counts.

Acceptance: every listed path is under `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/` or is one of the two `UtilitiesCS.Test` files; `Select-String -SimpleMatch 'orchestrator-state.json'` over that output reports 0 matching lines; `Select-String -SimpleMatch '.claude/'` over that output reports 0 matching lines; and no listed path is under `coverage/` or `TestResults/`. Each of those four checks and its count is recorded in the artifact. +- [ ] [P5-T4] Commit the staged set with a subject of the form `fix(782): correct the message-pinning claim and the baseline coverage input record` and a body stating that R3 and R4 are addressed, that R1 and R2 are accepted and waived as maintainer decisions with no file changed for either, and the two required trailers `Co-Authored-By: Claude Fable 5.1 ` and `Claude-Session: https://claude.ai/code/session_011ucgeqsVLVSVbmJfkDzcBs`.

Acceptance: the `pre-782-base` value still begins `736c2cf2` and equals the value [P0-T11] recorded; the `.claude` diff reports 0 lines; the C# diff lists exactly `UtilitiesCS.Test/Threading/UiThread_Tests.cs` and `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`; and the porcelain output lists only paths under this feature's `evidence/qa-gates/` sub-path plus `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/remediation-plan.2026-09-06T00-15.md`, which is modified because it carries the check-offs written since the [P5-T4] commit. This is the post-commit counterpart of [P4-T6]'s pre-commit porcelain enumeration; both are required because a name-listing diff cannot see an uncommitted path and a porcelain status goes empty once the change is committed. +- [ ] [P5-T6] Write `evidence/qa-gates/r-p5-t6-closure.md` recording: the [P5-T4] commit SHA and subject; a table of every task in this plan with its artifact path and pass or fail state; the R3 decision and the R4 decision with their reasoning as stated in this plan's preamble; the recorded R1 and R2 dispositions with a pointer to `evidence/other/r1-r2-maintainer-disposition.2026-09-06T00-15.md`; and the confirmation that no production `.cs` file, no file under `.claude/`, no file under `artifacts/orchestration/`, and neither `plan.2026-09-05T15-47.md` nor any reviewer artifact was changed.

[P5-T7], [P5-T8], and [P5-T9] have not yet run when this artifact is written, so their rows record `PENDING AT WRITE TIME` with that reason stated once beneath the table; every other row records a pass or fail state. +- [ ] [P5-T7] Stage these three paths explicitly and commit them with subject `docs(782): record remediation closure evidence` and the two required trailers: + + ```text + docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/qa-gates/r-p5-t3-staged-set.md + docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/qa-gates/r-p5-t5-post-commit-verification.md + docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/evidence/qa-gates/r-p5-t6-closure.md + ``` + + Acceptance: `git commit` exits 0; `git diff --cached --name-only` before the commit lists exactly those three paths and no other.

This task deliberately writes no artifact: any file it wrote would dirty the tree whose state it reports. +- [ ] [P5-T9] Mark [P5-T8] and [P5-T9] complete in this plan file, then stage `docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/remediation-plan.2026-09-06T00-15.md` alone and commit it with subject `docs(782): record remediation plan completion state` and the two required trailers `Co-Authored-By: Claude Fable 5.1 ` and `Claude-Session: https://claude.ai/code/session_011ucgeqsVLVSVbmJfkDzcBs`.

Both assertions +were the wildcard `"*UiThread.Init()*"`, and the pre-782 message likewise contains `UiThread.Init()`, +so the wildcard matched both messages and the claim was false as written. + +Of the two available options — make the assertion exact, or shrink the claim — this remediation took +the first: **make the acceptance criterion true rather than smaller.** Both assertions now read +`WithMessage(UiThread.DispatcherNotInitializedMessage)`, which FluentAssertions compares against the +entire message because the constant's value contains neither of its two wildcard characters. The cost +was two assertion lines and no production change. + +The corrected prose states exactly what that form establishes and no more: + +- a caller-specific tail appended at the `WpfDispatcherYield` throw site fails the assertion in + `WpfDispatcherYieldTests.cs`, and one appended at the `UiThread.Dispatcher` throw site fails the + assertion in `UiThread_Tests.cs`; +- neither assertion detects an edit to the constant's own wording, because an assertion written + against the constant moves with the constant; +- the one part of that wording a test does hold is the substring `UiThread.Init()`, asserted at + `WpfDispatcherYieldTests.cs:196`. + +The claim is observed, not derived.

Re-aggregating that document +yields 112359 and 26496 — the two figures the artifact itself labels superseded. + +The remediation took the combined option: **record both collections with their own inputs and +figures, keep the re-measured figures authoritative on substance, state that the authoritative +collection's output document is not retained, and supply a reproduction procedure.** The reasoning: + +- the re-measured figures were taken at the re-anchored base `736c2cf2`, this branch's actual base, + so they are correct on substance; promoting the retained document's figures would resurrect a + measurement of an orphaned tree and would contradict + `evidence/qa-gates/p7-t7-changed-line-coverage.md`, fixing one inconsistency by creating another; +- re-running the baseline collection was rejected: it would require restoring six files to + `pre-782-base` content in the delivered worktree and would yield a third measurement rather than a + confirmation of the second; +- the reconciling observation is that the retained document is the earlier collection's output. Its + companion log records `Total tests: 6992`, the superseded-base count, against the `6997` the + re-anchored run recorded. That discriminator is independent of file timestamps. + +## R1 and R2 dispositions + +R1 is **accepted with no remediation** and R2 is **waived**, following the reviewer's own +recommendations. **No file was changed for either item.** The full record, including the reviewer's +stated qualification that the "would force a FAIL verdict" rationale for SD1 is not a legitimate +reason to omit the artifact, is at +`evidence/other/r1-r2-maintainer-disposition.2026-09-06T00-15.md`. + +## Confirmations + +- **No production `.cs` file was changed.** The anchored diff in [P5-T5] lists exactly + `UtilitiesCS.Test/Threading/UiThread_Tests.cs` and + `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs`, both test files. + `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` was mutated temporarily by [P1-T5] and + reverted by [P1-T8]; it is absent from the diff. +- **No file under `.claude/` was changed**, including agent memory.

From faf08dfc6fafb8e92ec5da46adb99d09127710f4 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Sun, 6 Sep 2026 02:36:08 -0400 Subject: [PATCH 27/28] docs(782): add re-audit artifacts and correct two attribution defects The re-audit after remediation returns PASS with zero blocking findings. It re-executed every gate rather than reading the reported figures, reproduced all four coverage counters from the raw Cobertura documents, and read the TRX counters directly, including the falsification run that now backs the corrected message-pinning claim with an observation rather than a derivation. Fixes the two attribution defects the re-audit raised. The R1/R2 disposition record was titled a maintainer disposition, but the deciding party is the orchestrator and no maintainer ratification was sought. The heading is corrected and the consequence stated: the R2 coverage waiver rests on orchestrator judgment plus the reviewer's identical-uncovered-line-set evidence, not on the ratification CLAUDE.md requires for a formal COM/VSTO exemption. The filename keeps its original token because the remediation plan's acceptance conditions reference that exact path. AC-U2 permitted two production behavior changes, one of which was withdrawn under finding C03. The criterion was satisfied by a narrower change than it allowed for, which is true but read as though the withdrawn behavior had shipped. It now says so explicitly and points at issue #788.

Zero blocking findings. Three new non-blocking +accuracy nits are raised (N1, N2, N3), one of which corrects this reviewer's own cycle-1 record. + +The remediation's central problem was hard, and the delivery got it right. R3 asked for an assertion +that genuinely pins the message. The naive fix — replace a wildcard with a constant reference — is +close to tautological, because an assertion written against the same constant the production code +throws moves with that constant and pins nothing about its text. The delivery states that limitation +explicitly rather than claiming more than the change buys, identifies the one test that does hold the +literal (`WpfDispatcherYieldTests.cs:196`, `Message.Should().Contain("UiThread.Init()")`), and then +proves the property it does claim by observation rather than derivation: with the removed tail +appended at the `WpfDispatcherYield` throw site, `YieldAsync_WithoutDispatcher_RemainsStrict` fails +and its sibling passes. This reviewer read the TRX at `TestResults/782-r1-p1t7` directly and confirms +`outcome="Failed"`, 2 total, 1 passed, 1 failed. That is the standard of proof this reviewer asks for +and rarely receives. + +### Verified correct — re-derived at the new head, not carried forward from cycle 1 + +- **Toolchain.** This reviewer re-ran `dotnet tool run csharpier check .` (`Checked 1583 files`, exit + 0), the analyzer `msbuild /t:Rebuild` (`0 Warning(s) 0 Error(s)`, exit 0), and the nullable + `msbuild /t:Rebuild` (exit 0, 19 projects recompiled). `/t:Rebuild` means neither gate was vacuous. +- **Coverage held exactly.** Aggregating `782-r1-baseline.cobertura.xml` and + `782-r1-final.cobertura.xml` independently returns identical counters on both sides: + 112351/132961 lines and 26498/33480 branches under the delivery's selection, 55683/65896 and + 13249/16740 under a class-level selection that does not double-count. +- **R4 is confirmed by measurement.** The amended `evidence/baseline/p0-t7-coverage.md` claims the + retained document aggregates to 112359 and 26496. It does, exactly. The amendment's discriminating + observation — `Total tests: 6992` in the companion log versus 6997 in `p0-t6-vstest.md` — is the + right kind of evidence, because it is a value the run itself wrote rather than mutable filesystem + metadata. The amendment also declines to assert a mechanism for the missing document, which is the + correct posture when no record supports one. +- **The reflection consolidation actually consolidated.** A grep for the single-line token + `"_dispatcher"` across every `*.cs` in the repository returns exactly two hits: + `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs:117` and the unchanged + `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:136`. Six sites became + one per assembly, and the cross-assembly split is forced, not accidental: `UtilitiesCS` grants + `InternalsVisibleTo("UtilitiesCS.Test")` but not to `QuickFiler.Test`. +- **The split preserved every name.** Extracting method names from the pre-split file and from the + union of the two post-split files and comparing the sets: zero names lost, one name added (the C26 + synchronous sibling). Both parts declare `public partial class ProgressTracker_Tests` in namespace + `UtilitiesCS.Test`, so every fully-qualified name is preserved. `[TestClass]` and + `[DoNotParallelize]` sit on separate lines in exactly one part. Each file has exactly one + `` entry. +- **The seam's documented invariant holds.** `UiThreadDispatcherScope` declares in its `` + that it is deliberately not synchronized and that serialization is supplied by `[DoNotParallelize]` + on every installing class. This reviewer enumerated all five files that call `Install` or + `InstallNull` and confirmed each carries the attribute, including the new partial part, which + inherits it from the other part of the same type. A documented invariant that is actually true is + worth more than a lock. +- **`RibbonViewer` dead-guard removal is behavior-preserving.** `var dispatcher = UiThread.Dispatcher;` + throws when the static is unset — on `origin/main` as well as at head — so `dispatcher != null` was + already unreachable-false before the branch. Removing it changes nothing. This matters because the + file is invisible to coverage, so inspection is the only available check. +- **`ProgressTracker` / `ProgressTrackerAsync` C02 fix is a genuine no-op on value.** Line 33 assigns + `UiDispatcher = UiThread.Dispatcher`; line 39 previously re-read the static and now reads the + already-captured property. Same value, one fewer opportunity for a differing read. + +## Findings Table + +| ID | Severity | Blocking | File | Summary | +|---|---|---|---|---| +| N1 | Nit | No | `plan.2026-09-05T15-47.md:42`, `research/research.2026-09-05T16-10.md:6` | Absolute host path including the account name is embedded in two committed artifacts.

That +evidence sentence is true — the substitution is complete across all 90 changed files under +`evidence/` — but the criterion is stated over artifacts generally, and the plan and research +documents are artifacts of this delivery. This cycle records the row as FAIL and states the correction +explicitly rather than silently re-scoping the criterion to match the evidence. + +**Why it is nonetheless not blocking.** The prohibition is a reviewer convention, not repository +policy: no file under `.claude/rules/` and no section of `CLAUDE.md` states it. Its factual footing is +also weak — `git grep -l` over `docs/**` at the base commit returns **827 committed documents** already +carrying the same path. Two more occurrences change nothing about the repository's exposure. Raising +this to blocking would apply a standard to this branch that `origin/main` does not meet. + +Recommendation: substitute `` in the two lines if the delivery wants internal +consistency with its own evidence tree. Do not gate the pull request on it. + +## N2 — the disposition record asserts an authority no record supports + +`evidence/other/r1-r2-maintainer-disposition.2026-09-06T00-15.md` is titled "Maintainer disposition of +findings R1 and R2". Its body is accurate and, notably, reproduces in full this reviewer's cycle-1 +qualification that "would force a FAIL verdict" is not a legitimate reason to omit an artifact — +recorded rather than paraphrased away, which is the right call. + +The title, however, asserts that a maintainer made the decision. This reviewer looked for the record +and did not find it: + +- `artifacts/orchestration/orchestrator-state.json` carries a `remediation_disposition` object with + `decided_at: "2026-09-06T00:20:00Z"` and no actor field. Its `rationale_for_fixing_two_non_blocking_findings` + value is written in the orchestrator's voice. +- The same file's `human_interaction` key is `null`. +- The document's own body attributes itself correctly: "It is written by task [P3-T7] of the + remediation plan." + +So the recorded decider is the orchestrator, not the maintainer. It is entirely possible a human +ratified this in session and it simply was not logged; this finding states what the artifacts +support, not what did or did not happen. The concern is specific rather than procedural: `CLAUDE.md` +UT2 requires maintainer ratification for coverage exemptions, and R2 is adjacent enough to that class +that a title implying maintainer authority could later be cited as the ratification it is not. + +Recommendation: retitle to name the actual decider, or add a one-line maintainer ratification record. +Either resolves it. + +## N3 — AC-U2 names a behavior change that was withdrawn + +`user-story.md` AC-U2, checked `[x]`: + +> The delivery introduces no production behavior change other than the text of the +> `InvalidOperationException` message and the retry-after-failed-initialization behavior of +> `UiThread.Init()`, both of which are stated in the specification's Behavioral Contract. + +C03 — the latch re-arm that would produce that retry behavior — was withdrawn at commit `92c43665` +after a measured regression, and `UiThread.Init()` is byte-identical to its `pre-782-base` form. The +`spec.md` Behavioral Contract handles this correctly and at length: it states the method is unchanged, +gives the bisected regression, names the mechanism (the two lazy accessors retrying WinForms +construction and starving the thread pool against a 500 ms `CancelAfter`), and records the promotion +to #788. `spec.md` AC2 likewise routes C03 through its omission branch explicitly. + +AC-U2 alone was not updated. As a proposition it still holds — "no change other than A and B" is +satisfied by delivering only A — and the clause "both of which are stated in the specification's +Behavioral Contract" is literally true, since B is stated there as withdrawn. So this is staleness +rather than falsehood, and a reader who follows the pointer finds the full explanation. That is why it +is a nit and not a Should-fix. + +Recommendation: reword AC-U2 to name only the message text, or add "the latter withdrawn under SD18". + +## Design and Architecture Notes + +**The seam design is the right shape.** `UiThreadDispatcherScope` is 126 lines, `internal sealed`, +`IDisposable`, with a private constructor and three static entry points. The `Dispose` contract is +documented with the reasoning that matters: the captured prior is written back unconditionally and is +never tested for null first, because a null prior is a real state and skipping the write for it would +leak an installed dispatcher into every later test. That is precisely the bug the six ad-hoc sites +were prone to. + +**The failure mode is the improvement, not the deduplication.** The old sites used +`DispatcherField?.GetValue(null)` with a null-conditional, so a rename of `_dispatcher` would have +turned an order-independence guard into a silent no-op that still passed. The new resolution asserts +non-null in the static initializer, so a rename raises `TypeInitializationException` on first use and +fails every consuming test. `EmailMoveMonitorTests` had exactly the null-conditional shape and now +reads through `UiThreadDispatcherFixture.Current`. This is a real robustness gain, not a cosmetic one. + +**Two seams, two synchronization disciplines.** `UiThreadDispatcherScope` (UtilitiesCS.Test) is +explicitly unsynchronized and relies on `[DoNotParallelize]`; `UiThreadDispatcherFixture` +(QuickFiler.Test) takes a `FieldLock` on every read and write. Both write the same process-global +static. Within each assembly the discipline is sound and the invariant was verified to hold. Whether +the two assemblies can ever share a test host process, and therefore race across the seam boundary, +was not established by this review and is not asserted either way. It is pre-existing in structure — +the QuickFiler fixture is unchanged by this branch except for its new consumer — and is noted only so +a future reader does not assume the two seams are interchangeable. + +**The C21 test's cross-thread read is correctly synchronized.** `observed` is written on a worker and +read on the test thread after `worker.Join()`. `Thread.Join` supplies the happens-before edge, so no +`volatile` or memory barrier is needed. The test uses no sleep and no polling. + +**The `WpfDispatcherYield` comment correction is the most valuable prose change on the branch.** The +old comment asserted "UiThread.Dispatcher is set-once state populated by UiThread.Init() and is null +outside a live host", which PR #778 made false. The replacement states that the production fallback +provider throws directly and that the local guard is therefore unreachable on the production path, +covering only injected providers typed `Func` that exist only in tests. A reader can now +tell why the guard is there without reconstructing the history. + +## Policy Compliance Notes + +- **File size.** Every changed `.cs` file is under 500 lines; the maximum is 397. The branch removes a + pre-existing violation: `ProgressTracker_Tests.cs` was 514 and is now 271 plus a 288-line sibling. +- **Determinism.** No `Thread.Sleep`, `Task.Delay`, or wall-clock wait is added. The two pre-existing + `DateTime.Now` call sites are unchanged in count from the base commit. +- **Temp files.** None. The only added line containing the substring `Temp` is the word "Temporarily" + in an XML-doc summary. +- **Coverage exclusions.** `coverage.config` excludes only third-party module paths. The derived run + configuration appends `.*\.Test\.dll$`, which excludes test assemblies as the policy requires. No + `exclude` entry matches a production source path, so the Blocking condition in + `.claude/rules/general-unit-test.md` does not arise. +- **Evidence locations.** All 90 changed evidence files are under `/evidence//` across + six canonical kinds. Zero paths under any forbidden `artifacts/` sub-path. +- **`.claude/**` untouched.** `git diff --name-only 77c6d314..HEAD -- .claude` returns zero paths. The + delivery's own gate at `evidence/qa-gates/r-p5-t1-dotclaude-untouched.md` is independently confirmed. +- **Line endings.** `git ls-files --eol` reports `i/lf` for every committed file under the feature + folder; `.gitattributes` sets `* text=auto`. The executor's observation that three edited markdown + files are LF-only describes working-tree state only. Committed content is uniformly normalized, so + there is nothing to fix. +- **`REMEDIATION-BASE-SHA` occurrence count.** Confirmed: one occurrence at line start (line 23), two + under a containment reading (line 27 is a backticked mention naming the consumer). The executor's + line-start convention is the correct one and matches how the plan defines its other field keys. + Recording both measurements rather than picking one silently was the right disclosure. + +## Recommendation + +**GO for pull request.** Zero blocking findings, zero code defects requiring a fix before merge. + +The three new nits (N1, N2, N3) are all in documentation, all one-line edits, and all optional. If the +delivery elects to fix them — and the same reasoning that justified fixing R3 and R4 applies, since +this delivery exists to remove accuracy defects from audit artifacts — they can be handled in a single +commit without a toolchain pass, because none touches a `.cs` file. + +Two constraints on the pull request body: + +1. Close **#782 only**. #787 and #788 are follow-ups that must stay open, and the PR context + `Close candidates` author-asserted list is unusable: 22 entries scraped from prose, including + `#ISO-8601`, `#S2-1`, `#S3-1` through `#S4-2`, and eight unrelated real issues. +2.

Falsifiable sub-claim checked: every `EXIT_CODE:` line in the #584 evidence tree now matches `^EXIT_CODE: [0-9]+$` — a grep for lines failing that pattern returns zero. The S3-1 softenings are visible in the #584 policy-audit diff, for example row 2.15 losing the evaluative span "This is a provable assertion-level RED-first" in favour of a statement that the two artifacts' `Timestamp:` values do not establish execution order. | +| AC4 | PASS | `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` contains no `dispatcher != null` comparison; both guards removed at the lines the Write Set names. `ProgressTracker.cs:39` and `ProgressTrackerAsync.cs:39` each pass the captured `UiDispatcher` property rather than re-reading `UiThread.Dispatcher`; the value is identical because line 33 assigned it from that static one statement earlier. | +| AC5 | PASS | A grep over every `*.cs` file in the repository for the single-line token `"_dispatcher"` returns **exactly two** hits: `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs:117` and the unchanged `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:136`. `UtilitiesCS.Test` therefore holds exactly one acquisition. `EmailMoveMonitorTests.cs` holds no `FieldInfo`. The AC's own note on why `GetField("_dispatcher"` is not a usable search conjunction — CSharpier wraps the call so the two tokens never share a line — was confirmed correct. The restore-to-null assertion is present at `UiThread_Tests.cs:157-162`, which installs `expected` over a null prior inside an outer `InstallNull` scope. | +| AC6 | PASS | `ProgressTracker_Tests.cs` is 271 lines (was 514) and `ProgressTracker_ReportAndViewerTests.cs` is 288; both strictly under 500. Each has exactly one `` entry, at csproj lines 478 and 479. Both declare `public partial class ProgressTracker_Tests` in namespace `UtilitiesCS.Test`; `[TestClass]` and `[DoNotParallelize]` appear on separate lines in exactly one part (lines 14 and 15). Name preservation verified set-wise: extracting `[TestMethod]`-adjacent method names from the base file yields 21 names, from the union of the two head files yields 22, and the set difference of base minus head is **empty**, with the single addition being `Initialize_WhenDispatcherNotCaptured_ThrowsInvalidOperationException`. Every fully-qualified name is therefore preserved. | +| AC7 | PASS | All three tests exist and are named in the evidence. RED-first is recorded twice over: `evidence/regression-testing/p4-t7-fail-before.md` records `EXIT_CODE: 1` with both throws removed together — removing only one would leave the sibling guard throwing the same type with the same constant and make the demonstration vacuous, which the artifact states — and `p4-t8-pass-after.md` records `EXIT_CODE: 0` after `git checkout HEAD --` restore. The R3 falsification adds a third: TRX `TestResults/782-r1-p1t7` read directly by this reviewer records `outcome="Failed"`, 2 total, 1 passed, 1 failed. | +| AC8 | PASS | Two promoted entries exist with real issue numbers: `docs/features/potential/promoted/2026-09-05-uithread-init-accepts-non-sta-callers.md` (Issue #787, URL present) and `...-uithread-init-latch-not-rearmed-after-failed-initialize.md` (Issue #788, URL present). The upstream follow-up record is at `evidence/other/upstream-followups-drm-copilot.2026-09-05T23-02.md`. `git diff --name-only 77c6d314..HEAD -- .claude` returns zero paths, satisfying the AC's own evidence clause. | +| AC9 | PASS | Three of the four toolchain steps were re-executed by this reviewer at the current head and all exited 0: `csharpier check` (`Checked 1583 files`), the analyzer `msbuild /t:Rebuild` (`0 Warning(s) 0 Error(s)`), and the nullable `msbuild /t:Rebuild` (19 projects recompiled, no diagnostic). The fourth, the coverage-bearing test run, was verified from its committed TRX: 7000/7000/0. `evidence/qa-gates/r-p4-t7-loop-closure.md` records `PASS NUMBER: 1`. The package-level summary is committed at `evidence/qa-gates/coverage-summary.2026-09-05T23-11.md`. Changed-line coverage does not decrease: all seven changed executable production lines are covered at head, and no measurable file lost a covered line. `artifacts/csharp/coverage.xml` is not produced, as the AC itself states under SD1. | +| AC10 | PASS | `UiThread.cs:135-136` declares exactly one `internal const string DispatcherNotInitializedMessage`, referenced on two lines in that file (declaration and throw) and once in `WpfDispatcherYield.cs`. Zero occurrences of `before yielding folder tree work` and zero of `UiThread.Initialize()` remain in `UtilitiesCS`. The corrected claim is the one this reviewer required and it is now backed by observation: `evidence/regression-testing/r-p1-t7-fail-before.md` records the FluentAssertions failure verbatim, showing the expected value as the constant's whole text and the actual as that text plus the mutation's tail. The artifact also correctly labels its one derived leg — that the old wildcard would not have failed — as derived rather than observed. | +| AC11 | PASS | The method name `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` is unchanged; the assertion is `WithMessage(UiThread.DispatcherNotInitializedMessage)` at `UiThread_Tests.cs:144`. `evidence/qa-gates/r-p1-t10-assertion-token-gate.md` records the inversion 0 -> 2 for the constant form and 2 -> 0 for the wildcard form, scoped to the two files, using `-SimpleMatch` so the asterisks and parentheses are literal. The SD4 retention reason is recorded in the delivery code-review section (c). | +| AC12 | PASS | Both re-derivation artifacts exist and are non-empty: `evidence/baseline/p0-t9-584-spec-rederivation.md` (2,492 bytes) and `evidence/baseline/p0-t10-584-plan-rederivation.md` (3,197 bytes). | + +### Source: `user-story.md` + +| AC | Verdict | Verification performed by this reviewer | +|---|---|---| +| AC-U1 | NOT YET MET, correctly unchecked | No pull request exists. This is the one criterion whose satisfaction is external to the branch. It must be satisfied by a PR body that maps every finding identifier to its file or to its recorded omission reason, and that closes **#782 only**. | +| AC-U2 | PASS with a noted staleness | The proposition holds: the only production behavior deltas on the branch are the exception message text and the single-read capture in `UiThread.Dispatcher`, which closes a torn-read window. `RibbonViewer`'s guard removal is behavior-preserving because the getter already threw on the base commit; `ProgressTracker` and `ProgressTrackerAsync` read the same value from a local instead of re-reading the static. The AC also names "the retry-after-failed-initialization behavior of `UiThread.Init()`", which was withdrawn under SD18 and is not delivered; `Init()` is byte-identical to `pre-782-base`. Because the AC is phrased as an upper bound, delivering strictly less than it permits does not falsify it, and `spec.md`'s Behavioral Contract records the withdrawal in full. Recorded as non-blocking finding N3. | +| AC-U3 | PASS | Every #584 review finding is resolved, promoted, recorded as an upstream follow-up, or recorded as needing no action. The delivery code-review carries nine explicit disposition sections; the C-identifier and S-identifier disposition tables account for all twenty-six. Two promotions carry live issue numbers (#787, #788) and two push-down-owned items are recorded for drm-copilot. | +| AC-U4 | PASS | Spot-checked by re-deriving rather than by reading. The #584 formatter command cells now match the command actually run. The `EXIT_CODE:` normalization is verified by grep across the whole #584 evidence tree. The claim that this delivery's own figures are verifiable was tested end to end: this reviewer reproduced the coverage counters, the baseline document's figures, the TRX counters, and the toolchain exit codes from primary sources without relying on any prose summary. | +| AC-U5 | PASS | The toolchain passes in a single pass, independently confirmed for three of four gates. Changed-line coverage does not decrease. The `UiThread.cs` percentage moved from 77.11% to 76.83%, but the uncovered line set is identical in membership and line number on both sides — 19 lines, `28,29,30,32,33,34,67,68,69,70,71,72,73,74,75,76,118,119,120` — so no changed line regressed. The movement is arithmetic from a covered three-line wrapped `throw` collapsing to one line. | + +## Summary + +**Feature verdict: PASS.** + +| Metric | Value | +|---|---| +| Acceptance criteria evaluated | 17 | +| PASS | 16 | +| NOT YET MET (external dependency) | 1 (AC-U1, pending the pull request) | +| PARTIAL | 0 | +| FAIL | 0 | +| UNVERIFIED | 0 | +| Failing for a reason attributable to the delivery | 0 | + +No acceptance criterion is UNVERIFIED. Every criterion was checked against a primary source: the +working tree, the base commit, raw Cobertura XML, committed TRX documents, or a command this reviewer +executed. + +### What the remediation changed, assessed + +R3 and R4 were both accuracy defects in the delivery's own artifacts, and both are now fixed correctly. +The R3 fix is notable for what it declines to claim. A constant-reference assertion pins the throw +site's use of the constant, not the constant's text, and the delivery says so in three places rather +than letting the stronger reading stand. It then locates the one assertion that does hold the literal +and cites it by file and line. The preflight rounds that caught two successive false framings of this +same claim did real work; the second correction, refuted by `WpfDispatcherYieldTests.cs:196`, is +exactly the kind of near-miss that ships silently in most deliveries. + +The R4 fix records both baseline collections with their own inputs and figures instead of choosing one +and discarding the other, states which is authoritative and why, and marks the authoritative +collection's output document as not retained. It further declines to assert a mechanism for that +document's absence, on the stated grounds that no record supports one. That restraint is correct and +is the harder choice. + +### Residuals carried forward + +None blocks. Three non-blocking accuracy nits are raised in +`remediation-inputs.2026-09-06T02-18.md`: N1 (absolute host paths in two committed artifacts, which +also corrects this reviewer's cycle-1 row 2.11), N2 (a disposition record titled as a maintainer +disposition with no maintainer ratification on record), and N3 (AC-U2's stale reference to the +withdrawn C03 behavior). R1 and R2 recur unchanged from cycle 1 because both are properties of scope +decisions rather than of the remediation; both carry a written disposition. + +## Acceptance Criteria Check-off + +This reviewer checked off **no** acceptance criteria this cycle. All 12 `spec.md` criteria were already +`[x]` and all were evaluated PASS, so no state change was warranted. The single unchecked criterion, +AC-U1, evaluates to NOT YET MET and must stay `- [ ]` until a pull request exists. Per the +acceptance-criteria-tracking protocol, an item is checked only after the work satisfying it is +delivered and verified; no pull request has been created, so checking it would be a phantom check-off. + +No AC text was modified.

Three new +non-blocking accuracy findings (N1, N2, N3) are raised, of which N1 is a correction to this +reviewer's own cycle-1 row 2.11. + +## Rejected Scope Narrowing + +The caller's prompt did **not** attempt to narrow the audit scope.

The three bucket counts sum to 110, which is exactly the + `.md` file count, so all 16 code files are absent from every bucket rather than misfiled into one. + This did not narrow the audit, because the changed-file set was derived from + `git diff --numstat 77c6d314..HEAD` and not from the summary.

The kinds used are + `baseline` (20), `qa-gates` (43), `regression-testing` (9), `remediation-baseline` (12), `other` + (7), `issue-updates` (1). All six are canonical per + `.claude/skills/evidence-and-timestamp-conventions/SKILL.md`. +- `validate_evidence_locations.py` does not exist in this repository.

General Unit Test Policy Compliance + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 1.1 | Independence — tests run in any order | PASS | Every test class that installs into the process-global `UiThread._dispatcher` carries `[DoNotParallelize]`: `WpfDispatcherYieldTests` (13), `IdleAsyncQueue_Tests` (29), `ProgressTrackerAsync_Tests` (13), `UiThread_Dispatcher_Tests` (129), and `ProgressTracker_Tests` (15, inherited by the new partial part). Verified by enumerating every file referencing `UiThreadDispatcherScope.Install`/`InstallNull` and reading its class attributes. This is exactly the invariant the seam's own `` declares. | +| 1.2 | Isolation — one unit per test | PASS | The three new tests each pin one throw site. `YieldAsync_ProductionFallbackWithoutDispatcher_ThrowsNamingInit` reaches only the `WpfDispatcherYield` guard; the two C26 tests pin `ProgressTracker.Initialize()` and `ProgressTrackerAsync.InitializeAsync()` separately. | +| 1.3 | Fast execution | PASS | 7000 tests in a single run; the TRX records no timeout and no abort. | +| 1.4 | Determinism | PASS | No `Thread.Sleep`, `Task.Delay`, or wall-clock wait is added by this branch. The two `DateTime.Now` occurrences in `IdleActionQueue_Tests.cs:247` and `IdleAsyncQueue_Tests.cs:132` are pre-existing: `git show : \| grep -c DateTime.Now` returns 1 for each file, unchanged at head. The C21 test synchronizes by `Thread.Join()`, which supplies the happens-before edge for the cross-thread read of `observed`. | +| 1.5 | Readability, AAA, documented intent | PASS | The new tests carry explicit `// Arrange` / `// Act` / `// Assert` comments and XML-doc summaries. Assertion reasons are supplied (`"the production fallback must surface the uncaptured-dispatcher guard"`). | +| 1.6 | No external dependencies, no temp files | PASS | Grep over all changed `.cs` files for `Path.GetTempPath`, `GetTempFileName`, and `Temp` returns no added line. The only added line containing `Temp` is the word "Temporarily" in an XML-doc summary. | +| 1.7 | Coverage exclusion policy — no production path excluded by config | PASS | `coverage.config` excludes only third-party module paths (Deedle, FSharp, Castle.Core, FluentAssertions, Moq, Microsoft.Testing, MSTest). The derived run configuration appends `.*\.Test\.dll$`, which excludes test assemblies as the policy requires rather than production code. No `exclude` entry matches a production source path. | +| 1.8 | Test file location | PASS (repo convention) | Tests live in per-project `.Test/` assemblies mirroring the production tree. The `tests/` layout named in `.claude/rules/general-unit-test.md` is not the layout of this .NET Framework solution; this divergence is repository-wide and pre-existing on `main`, and the branch introduces no new deviation. The new helper lands in `UtilitiesCS.Test/TestHelpers/`, a test-support directory, not in a production tree. | + +### 1.2.1 Per-Language Coverage Comparison + +Every language with changed files on the branch receives an explicit PASS or FAIL below. Languages +with zero changed files are listed for completeness and carry PASS. + +| Language | Changed files on branch | Coverage artifact | Repo-wide line coverage | Repo-wide branch coverage | Verdict | +|---|---|---|---|---|---| +| C# | 15 `.cs` + 1 `.csproj` | `artifacts/csharp/coverage.xml` absent; raw Cobertura present at `coverage/782-r1-final.cobertura.xml` | 84.50% (55683/65896) | 79.15% (13249/16740) | FAIL | +| PowerShell | 0 | not required | zero changed files, so the pester line and Pester command coverage thresholds have no subject on this branch | Pester measures no branch percentage, so no branch threshold applies | PASS | +| Python | 0 | not required | zero changed files, so the python line coverage threshold has no subject on this branch | zero changed files, so the python branch coverage threshold has no subject on this branch | PASS | +| TypeScript | 0 | not required | zero changed files, so the typescript line coverage threshold has no subject on this branch | zero changed files, so the typescript branch coverage threshold has no subject on this branch | PASS | + +The C# row reads **FAIL** because 84.50% is below the 85% uniform line floor in +`.claude/rules/quality-tiers.md` and `.claude/rules/general-unit-test.md`. The branch figure 79.15% +clears the 75% floor. Under `CLAUDE.md`'s 80% testable-denominator floor the same measurement passes. +The 80-versus-85 divergence between `CLAUDE.md` and `.claude/rules/` is unreconciled and pre-exists on +`origin/main`; this audit reports against the stricter `.claude/rules/` figure and records the +disposition below. + +**Disposition of the C# FAIL row: non-blocking.** The branch does not move the figure. This +reviewer's own aggregation of `coverage/782-r1-baseline.cobertura.xml` and +`coverage/782-r1-final.cobertura.xml` returns byte-equal counters on both sides — 112351/132961 lines +and 26498/33480 branches under the delivery's pinned selection, 55683/65896 and 13249/16740 under the +class-level selection. Numerator and denominator are unchanged, so the shortfall is entirely +inherited from `origin/main` and none of it is attributable to this delivery. + +### 1.2.2 Coverage Evidence Checklist + +| Item | State | Note | +|---|---|---| +| Canonical C# artifact `artifacts/csharp/coverage.xml` | ABSENT | The `artifacts/csharp/` directory does not exist.

General Code Change Policy Compliance + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 2.1 | Simplicity first | PASS | Six independently written reflection sites collapse to one `internal sealed` scope; a 514-line file becomes two partial parts of 271 and 288 lines. Both reduce indirection rather than adding it. | +| 2.2 | Reusability | PASS | `UiThreadDispatcherScope` replaces four duplicated acquisition-and-restore passages in `UtilitiesCS.Test`. | +| 2.3 | Extensibility, no breaking public API change | PASS | `DispatcherNotInitializedMessage` is `internal const`, reachable from `UtilitiesCS.Test` through the existing `InternalsVisibleTo` grant at `UtilitiesCS/Properties/AssemblyInfo.cs:19`. `UiThread.Dispatcher` keeps its signature and its exception type. | +| 2.4 | Separation of concerns | PASS | The message text moves to one constant consumed by two throw sites in the same assembly; no I/O is introduced. | +| 2.5 | Error handling — fail fast, no silent swallow | PASS | The seam's field resolution asserts non-null with a stated reason, so a rename of `_dispatcher` raises `TypeInitializationException` on first use instead of degrading to a no-op guard. That is the defect class C12/C13 were raised against. | +| 2.6 | File size limit — 500 lines | PASS | Every changed `.cs` file measured at head: 397, 341, 328, 317, 288, 278, 271, 266, 256, 231, 215, 195, 126, 109, 76. Maximum 397. `ProgressTracker_Tests.cs` was 514 at base and is 271 at head, so the branch removes a pre-existing violation. | +| 2.7 | Naming | PASS | `PascalCase` types and members, `camelCase` locals, `_camelCase` private fields throughout the changed set. | +| 2.8 | Comment why, not what; comments match behavior | PASS | The three corrected comment passages (`WpfDispatcherYield.cs:53-59`, `EmailMoveMonitorTests.cs:27-40`, `QfcItemController.InitializationTests.Part2.cs:121-131`) each replace a claim falsified by PR #778 with the mechanism the code has today. Verified by reading both sides of the diff. | +| 2.9 | Mandatory toolchain loop, one uninterrupted pass | PASS | Re-executed by this reviewer: format check, analyzer build, nullable build all exit 0 at the current head. The delivery's own loop-closure record `evidence/qa-gates/r-p4-t7-loop-closure.md` states `PASS NUMBER: 1`. | +| 2.10 | Dependencies — none added | PASS | No `packages.config`, `.csproj` ``, or `` change. The only `.csproj` edit adds two `` entries. | +| 2.11 | No absolute host paths in artifacts | FAIL | **Correction to this reviewer's cycle-1 row 2.11, which recorded PASS.** Two committed artifacts embed the absolute host path including the account name: `plan.2026-09-05T15-47.md:42` and `research/research.2026-09-05T16-10.md:6`, both reading `C:\Users\DanMoisan\repos\TaskMaster-wt\2026-09-05T10-47`. The cycle-1 evidence sentence was scoped to `evidence/` artifacts, where the substitution is genuinely complete; the criterion is stated over artifacts generally. Non-blocking: 827 committed documents under `docs/` on `origin/main` already carry the same path, no `.claude/rules/` file or `CLAUDE.md` section codifies the prohibition, and the two occurrences are a negligible addition to an established repository-wide pattern. Recorded as finding N1. | +| 2.12 | Bugfix workflow — failing regression test first | PASS | Three separate RED-first records exist and are corroborated by committed TRX counters: `evidence/regression-testing/p4-t7-fail-before.md` (exit 1, both guards removed together so the demonstration is not vacuous), `p4-t8-pass-after.md` (exit 0 after `git checkout HEAD --` restore), and `r-p1-t7-fail-before.md` (TRX `outcome="Failed"`, 2 total, 1 failed). | + +## 3. Language-Specific Code Change Policy Compliance (C#) + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 3.1 | CSharpier formatting via `dotnet tool run` | PASS | This reviewer ran `dotnet tool run csharpier check .`: `Checked 1583 files in 4405ms`, exit 0. The count equals the delivery's recorded 1583, so the processed file set is unchanged. `dotnet format` was not used anywhere on the branch. | +| 3.2 | .NET analyzers, `EnableNETAnalyzers` + `EnforceCodeStyleInBuild` | PASS | This reviewer ran the exact CLAUDE.md command with `/t:Rebuild`: `Build succeeded. 0 Warning(s) 0 Error(s)`, exit 0. | +| 3.3 | Nullable / type checking with `TreatWarningsAsErrors=true` | PASS | This reviewer ran the exact `.github/workflows/_build-nullable.yml` command with `/t:Rebuild`: exit 0, all 19 projects recompiled, no diagnostic emitted. `/p:Nullable=enable` was correctly not passed. | +| 3.4 | Per-file nullable opt-in respected | PASS | `UtilitiesCS/Threading/UiThread.cs` carries `#nullable enable` and the edited getter participates in flow analysis. The new `UiThreadDispatcherScope.cs` uses `#nullable enable annotations` / `#nullable restore annotations`, which is the established idiom in this assembly (17 occurrences of each). Noted as informational finding N8: annotations-only means the file receives no `CS86xx` flow analysis. | +| 3.5 | Strong contracts, explicit APIs, XML docs on non-obvious behavior | PASS | `UiThread.Dispatcher` gains ``, ``, and ``. The `` states why this accessor deliberately does not self-heal by calling `Init()`, which is the contract question a reader would otherwise have to reconstruct from the sibling accessors. | +| 3.6 | Null-safety by default | PASS | The getter now reads the non-volatile static exactly once into a local and returns that local, closing the torn-read window C02 identified. | +| 3.7 | Banned symbols (`BannedSymbols.txt`) | PASS | No added line introduces `DateTime.Now`, `DateTime.UtcNow`, `Random.Shared`, `Thread.Sleep`, or `Task.Delay`. The two pre-existing `DateTime.Now` call sites are unchanged in count. RS0030 is held at `severity = suggestion` per `.claude/rules/csharp.md:79`. | +| 3.8 | MSTest / Moq / FluentAssertions only | PASS | The changed tests use `[TestClass]`, `[TestMethod]`, `[TestInitialize]`, `[TestCleanup]`, `[DoNotParallelize]` from `Microsoft.VisualStudio.TestTools.UnitTesting`, and FluentAssertions for assertions. No xUnit or NUnit reference is introduced. | + +## 4. Language-Specific Unit Test Policy Compliance (C#) + +| # | Requirement | Verdict | Evidence | +|---|---|---|---| +| 4.1 | MSTest framework | PASS | Verified across all seven changed test files. | +| 4.2 | Moq for mocks | PASS | `EmailMoveMonitorTests` retains its Moq usage; the new tests use hand-written fakes (`CountingDispatcherProvider`, `StaDispatcherHost`) where a mock would add no isolation. | +| 4.3 | FluentAssertions preferred | PASS | Both rewritten assertions use `Should().Throw().WithMessage(...)`. The seam's field check uses `Should().NotBeNull(because: ...)`. | +| 4.4 | Scenario completeness — positive, negative, edge, error | PASS | The delivery adds the negative path for three throw sites and the C21 edge case, a worker thread with no dispatcher of its own reaching the production fallback. `AC5` also requires and gets a restore-to-null assertion after scope disposal. | +| 4.5 | Assertion pins the intended property | PASS | `WithMessage(UiThread.DispatcherNotInitializedMessage)` contains neither `*` nor `?`, so FluentAssertions compares the pattern against the whole message. Observed, not derived: `evidence/regression-testing/r-p1-t7-fail-before.md` records the assertion failing when the removed tail is appended at the `WpfDispatcherYield` throw site, and the committed TRX at `TestResults/782-r1-p1t7` corroborates it with `outcome="Failed"`, 2 total, 1 passed, 1 failed, the failure being `WpfDispatcherYieldTests.YieldAsync_WithoutDispatcher_RemainsStrict`. | +| 4.6 | The constant's own text remains pinned by some test | PASS | `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs:196` asserts `observedException.Message.Should().Contain("UiThread.Init()")`. This is an independent literal that does not move with the constant, so an edit to the constant's wording that dropped `UiThread.Init()` would fail. The delivery states this limitation explicitly rather than overclaiming; verified as accurate. | + +## 5. Test Coverage Detail + +All figures below were produced by this reviewer directly from the Cobertura XML, not read from a +delivery artifact. + +### 5.1 Repo-wide, first-party (nine production assemblies) + +First-party allowlist: `Tags`, `ToDoModel`, `TaskVisualization`, `UtilitiesCS`, `QuickFiler`, +`TaskTree`, `TaskMaster`, `SVGControl`, `VBFunctions`. Vendor packages present in the document +(`log4net`, `Microsoft.IO.RecyclableMemoryStream`, `Mono.Reflection`, `System.Interactive`, +`System.Linq.Async`) are excluded from the numerator and denominator. + +| Selection | Document | Lines | Line % | Branches | Branch % | +|---|---|---|---|---|---| +| `classes/class/lines/line` (class-level, no double count) | `782-r1-baseline` | 55683/65896 | 84.5013 | 13249/16740 | 79.1458 | +| `classes/class/lines/line` (class-level, no double count) | `782-r1-final` | 55683/65896 | 84.5013 | 13249/16740 | 79.1458 | +| `.//line` (the delivery's pinned SD22 selection) | `782-r1-baseline` | 112351/132961 | 84.4992 | 26498/33480 | 79.1458 | +| `.//line` (the delivery's pinned SD22 selection) | `782-r1-final` | 112351/132961 | 84.4992 | 26498/33480 | 79.1458 | + +Both sides are byte-equal on all four counters under both selections. The delivery's claim that +coverage held exactly is **confirmed**. + +The two selections disagree by 0.0021 points on lines and not at all on branches. The `.//line` form +double-counts, because a Cobertura `` carries both a class-level `` block and a +per-method `` block over the same source lines; the document's own root attribute +`lines-valid="83068"` is smaller than the 132961 the `.//line` form reports over a strict subset of +packages, which is the direct proof. The double count is close enough to uniform that no percentage +the delivery states is materially wrong, and every comparison the delivery draws uses the same +selection on both sides. Recorded as informational finding N4, not as a defect. + +### 5.2 Canonical coverage artifact presence + +| Language | Expected path | Present | Verdict | +|---|---|---|---| +| C# | `artifacts/csharp/coverage.xml` | No | FAIL | +| PowerShell | `artifacts/pester/powershell-coverage.xml` | No | PASS, zero changed `.ps1` or `.psm1` files on the branch | +| Python | `artifacts/python/lcov.info` | No | PASS, zero changed `.py` files on the branch | +| TypeScript | `coverage/lcov.info` | No | PASS, zero changed `.ts` or `.tsx` files on the branch | + +The C# row is FAIL under the artifact-absence rule.

See finding R1. + +### 5.3 New production files + +**None.** The branch adds two files, both under `UtilitiesCS.Test` +(`TestHelpers/UiThreadDispatcherScope.cs`, 126 lines, and +`Threading/ProgressTracker_ReportAndViewerTests.cs`, 288 lines). Both are test modules, which the +derived run configuration removes from the denominator via `.*\.Test\.dll$` +exactly as the coverage exclusion policy requires. The new-code line floor therefore has no +production subject on this branch. + +### 5.4 Modified production files + +| File | Base lines | Head lines | Base % | Head % | Base branch | Head branch | Changed-line regression | Verdict | +|---|---|---|---|---|---|---|---|---| +| `UtilitiesCS/Threading/UiThread.cs` | 64/83 | 63/82 | 77.11 | 76.83 | 13/20 = 65.00 | 13/20 = 65.00 | No | FAIL | +| `UtilitiesCS/OutlookObjects/Folder/WpfDispatcherYield.cs` | 27/28 | 26/26 | 96.43 | 100.00 | 14/14 = 100.00 | 14/14 = 100.00 | No | PASS | +| `UtilitiesCS/Threading/ProgressTracker.cs` | 149/170 | 149/170 | 87.65 | 87.65 | 33/40 = 82.50 | 33/40 = 82.50 | No | PASS | +| `UtilitiesCS/Threading/ProgressTrackerAsync.cs` | 43/47 | 43/47 | 91.49 | 91.49 | 5/6 = 83.33 | 5/6 = 83.33 | No | PASS | +| `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` | absent | absent | not measured | not measured | not measured | not measured | Cannot be measured | FAIL | + +Baseline column read from `coverage/782-p0-baseline.cobertura.xml`, head column from +`coverage/782-r1-final.cobertura.xml`, both aggregated by this reviewer with the class-level +selection and de-duplicated by line number across partial-class and nested-type entries sharing a +filename. + +**`UiThread.cs` FAIL, disposition non-blocking.** The decisive measurement is the uncovered line set, +not the percentage. This reviewer re-derived it at the new head: + +```text +BASELINE uncovered (19): 28,29,30,32,33,34,67,68,69,70,71,72,73,74,75,76,118,119,120 +HEAD uncovered (19): 28,29,30,32,33,34,67,68,69,70,71,72,73,74,75,76,118,119,120 +IDENTICAL SETS: True +``` + +Not one line moved from covered to uncovered. The -0.28 point movement is arithmetic: a covered +three-line wrapped `throw` collapsed to a single line when routed through the shared constant, so the +numerator and the denominator each fell by one against a residue fixed at 19. That residue sits in +`ThreadMonitor` construction inside `Initialize()` (lines 67-76) and in two other host-bound blocks, +none of which the branch touches. Branch coverage is unchanged at 65.00%. See finding R2. + +**`RibbonViewer.EngineCommands.cs` FAIL, disposition non-blocking.** The file is absent from every +Cobertura document, baseline and head alike, because `RibbonViewer` carries `[ExcludeFromCodeCoverage]` +on the `RibbonViewer.cs` partial. That attribute is **pre-existing on `origin/main`** at +`RibbonViewer.cs:32`, verified by `git show 77c6d314:TaskMaster/Ribbon/RibbonViewer.cs`. It falls under +the COM/VSTO exemption ratified in `CLAUDE.md` UT2 for VSTO ribbon event handlers. The two changed +lines are therefore unmeasurable, and this reviewer verified them by inspection instead: removing +`dispatcher != null &&` from `if (dispatcher != null && !dispatcher.CheckAccess())` is +behavior-preserving, because the preceding statement `var dispatcher = UiThread.Dispatcher;` throws +`InvalidOperationException` when the static is unset on `origin/main` as well as at head, so the +comparison was already dead before the branch. Recorded as informational finding N5. + +### 5.5 Changed-line coverage + +**PASS.** Seven executable production lines changed across the four measurable production files, and +every one of them is covered at head. The remediation phase changed no production `.cs` file at all — +the only two files it edited are `UtilitiesCS.Test/OutlookObjects/Folder/WpfDispatcherYieldTests.cs` +and `UtilitiesCS.Test/Threading/UiThread_Tests.cs`, both excluded from the denominator by the derived +configuration — so the changed-line metric has an empty domain for the remediation considered alone +and is evaluated over the whole branch instead, where it passes.

The document's own body correctly attributes itself to plan task [P3-T7]. | +| N3 | `user-story.md` AC-U2 names "the retry-after-failed-initialization behavior of `UiThread.Init()`" as a delivered production behavior change | Nit | No | New this cycle. C03 was withdrawn; `Init()` is byte-identical to `pre-782-base`. The AC is an upper bound so it is not false, and `spec.md` records the withdrawal in full, but the phrasing is stale relative to final scope. | +| N4 | The pinned SD22 `.//line` aggregation double-counts method-level rows | Informational | No | Percentage impact 0.0021 points; both sides of every comparison use the same selection; no stated figure is materially wrong. | +| N5 | `RibbonViewer.EngineCommands.cs` changed lines are unmeasurable | Informational | No | Type-level `[ExcludeFromCodeCoverage]` pre-existing on `origin/main`; ratified COM/VSTO exemption; the two changed lines verified behavior-preserving by inspection. | +| N6 | PR context summary reports `Core logic changes: 0 files` against 16 changed code files | Informational | No | Generator defect, not a delivery defect. Consequence simulated below. | +| N7 | PR context `Close candidates` author-asserted list contains 22 entries scraped from prose | Informational | No | Includes non-issues `#ISO-8601`, `#S2-1`, `#S3-1` through `#S4-2`, and unrelated issues #394, #449, #476, #493, #508, #584, #778, #780. The PR must close #782 only. | +| N8 | `UiThreadDispatcherScope.cs` uses `#nullable enable annotations`, not `#nullable enable` | Informational | No | Consistent with the assembly idiom (17 occurrences). Means the file receives annotation syntax without `CS86xx` flow analysis, so the nullable gate is a no-op over it. | +| SD1 | `artifacts/csharp/coverage.xml` deliberately not produced | Scope decision | No | Documented in `spec.md` Constraint 11 and Non-Goals. This reviewer restates the cycle-1 qualification: "producing the artifact would force a FAIL verdict" is not a legitimate reason to omit it, and the FAIL is recorded regardless. The acceptance rests on the substitute evidence. | +| SD4 | `Dispatcher_WhenBackingFieldIsNull_ThrowsInvalidOperationExceptionNamingInitialize` retains a name that no longer matches the message | Scope decision | No | Renaming would make a `TestCaseFilter` expression recorded in a committed #584 evidence artifact resolve to zero tests. Recorded in the delivery's code-review artifact section (c). | +| SD5 | The `WpfDispatcherYield` message tail "before yielding folder tree work" is removed | Scope decision | No | Now correctly characterized after the R3 fix: the shared-constant assertion fails on a tail appended at that throw site, observed at `evidence/regression-testing/r-p1-t7-fail-before.md`. | +| SD18 | C03 latch re-arm withdrawn | Scope decision | No | Withdrawn on a measured regression, bisected to the single re-arm line; promoted as #788. | +| DC1 | `CLAUDE.md` states an 80% repo-wide floor and a 90% new-code floor; `.claude/rules/` states a uniform 85% line and 75% branch floor | Doc conflict | No | Unreconciled and pre-existing on `origin/main`. This audit reports against the stricter `.claude/rules/` figure. | + +### Coverage hook simulation + +The SubagentStop hook `.claude/hooks/validate-feature-review-coverage.ps1` derives its changed-language +set from `artifacts/pr_context.summary.txt` by matching `^\s*-\s+(\S+)\s+\(\+\d+/-\d+\)\s*$`. This +reviewer dot-sourced the hook and ran `Get-ChangedLanguageSet` against the current summary: **10 +matching lines, all `.md`, producing an empty changed-language set**. The hook therefore performs the +three artifact-path checks and returns before any per-language coverage check runs. The explicit +PASS and FAIL verdicts in section 1.2.1 are supplied under this audit's own scope invariant, not +because the hook demands them. + +## 9.

The discriminating observation the amendment uses — `Total tests: 6992` in the companion log versus 6997 in `p0-t6-vstest.md:71` — is the right kind of evidence, because it is a value the run wrote rather than mutable filesystem metadata. | + +## R1 — Canonical C# coverage artifact absent (procedural, recommend accept again) + +**Trigger:** "coverage artifact absent for any language that has changed files." + +**Reason, as the contract requires it be stated:** coverage artifact absent for C#; coverage +verification is mandatory for all languages with changed files. + +**Facts, re-derived at the new head.** + +- `artifacts/csharp/coverage.xml` does not exist.

Only AC-U2 was not updated. + +**Why it is a nit and not a Should-fix.** As a proposition the AC still holds: "no production behavior +change other than A and B" is satisfied by delivering only A. The trailing clause "both of which are +stated in the specification's Behavioral Contract" is also literally true, since B is stated there as +withdrawn. A reader who follows the pointer finds the full explanation. This is staleness relative to +final scope, not a false claim. + +**Recommended fix, if elected.** Reword AC-U2 to name only the message text, or append "the latter +withdrawn under SD18 and promoted as #788". One line in an AC source document; no AC state change. + +## Informational findings — no action requested + +These are recorded so a future reader does not rediscover them. None is a defect of this delivery and +none requires a change on this branch. + +| ID | Observation | +|---|---| +| N4 | The delivery's pinned SD22 `.//line` Cobertura selection double-counts: a `` carries both a class-level `` block and per-method `` blocks over the same source lines. The proof is internal to the document — its own root attribute `lines-valid="83068"` is smaller than the 132961 the `.//line` form reports over a strict subset of packages. The impact is 0.0021 points (84.4992% versus a class-level 84.5013%) and both sides of every comparison use the same selection, so no figure the delivery states is materially wrong. Future work should prefer `classes/class/lines/line` de-duplicated by line number. | +| N5 | `TaskMaster/Ribbon/RibbonViewer.EngineCommands.cs` has two changed lines and is absent from every Cobertura document, baseline and head alike, because `RibbonViewer` carries `[ExcludeFromCodeCoverage]` on the `RibbonViewer.cs` partial. That attribute is pre-existing on `origin/main` at `RibbonViewer.cs:32` and falls under the ratified COM/VSTO exemption in `CLAUDE.md` UT2. The changed lines were verified behavior-preserving by inspection instead: `var dispatcher = UiThread.Dispatcher;` throws when the static is unset on the base commit as well as at head, so `dispatcher != null` was already unreachable-false before the branch. | +| N6 | `artifacts/pr_context.summary.txt` reports `Core logic changes: 0 files` while 15 `.cs` and 1 `.csproj` file changed. The three bucket counts sum to 110, exactly the `.md` count, so all 16 code files are absent from every bucket rather than misfiled. Consequence, simulated by dot-sourcing the hook: `Get-ChangedLanguageSet` returns an **empty** language set from this summary, so `.claude/hooks/validate-feature-review-coverage.ps1` performs only its artifact-path checks. This is a recurring generator defect, not a delivery defect. | +| N7 | The `Close candidates` author-asserted list in the same summary holds 22 entries scraped from prose, including the non-issues `#ISO-8601`, `#S2-1`, and `#S3-1` through `#S4-2`, plus eight unrelated real issues (#394, #449, #476, #493, #508, #584, #778, #780). The only issue this branch closes is **#782**. #787 and #788 must remain open. | +| N8 | `UtilitiesCS.Test/TestHelpers/UiThreadDispatcherScope.cs` opens with `#nullable enable annotations` rather than `#nullable enable`. This is the established idiom in the assembly (17 occurrences of each of the enable and restore forms) and is consistent, but it means the file receives annotation syntax without `CS86xx` flow analysis, so the nullable gate is a no-op over it. `ResolveDispatcherField` assigns a possibly-null `FieldInfo` to a non-nullable local without a diagnostic; the subsequent `Should().NotBeNull(because: ...)` makes the runtime behavior safe, so this is a gate-coverage note rather than a defect. | + +## Handoff + +No remediation is required for merge. If the delivery elects to close N1, N2, and N3, the same +reasoning that justified fixing R3 and R4 applies — this delivery exists to remove accuracy defects +from audit artifacts, and all three are accuracy defects in its own artifacts. All three are +documentation-only, total four edited lines across three files, touch no `.cs` file, and therefore +require no toolchain pass and cannot move any coverage counter. They can be handled in one commit. + +If they are instead accepted as-is, record the acceptance in the delivery's evidence with the actual +decider named, which is itself the substance of N2. diff --git a/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md b/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md index 3ab2d7a48..0011572d3 100644 --- a/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md +++ b/docs/features/active/2026-09-05-pr-778-post-merge-review-residuals-782/user-story.md @@ -73,8 +73,13 @@ Observable, in this order: - [ ] AC-U1: One branch and one pull request deliver all in-scope findings; the pull request body maps every finding identifier to the file that changed or to the recorded reason it did not. - [x] AC-U2: The delivery introduces no production behavior change other than the text of the - `InvalidOperationException` message and the retry-after-failed-initialization behavior of - `UiThread.Init()`, both of which are stated in the specification's Behavioral Contract. + `InvalidOperationException` message, which is stated in the specification's Behavioral + Contract.
