Verified empirically: `artifacts/csharp/final-coverage.cobertura.xml` contains no `class name="QuickFiler.ItemViewer"` and no `filename` ending `ItemViewer.Breadcrumb.cs`. **Any AC demanding ">= 90% coverage on new or changed code" in this type is structurally unmeasurable.** Plan a decidable two-branch determination keyed on a class-element count query, not an executor judgment, and supply named-test branch evidence as the substitute. Same trap applies to any type in this repo carrying the attribute — check before writing a changed-line coverage gate. + +2. **A guard swap invalidates its own sibling comments.** `EnsureBreadcrumbResourceOwnership` (lines 380-388) carries a statement-order comment that names `UiSyncContext` and "a SynchronizationContext comparison"; the guard's own `` claims "a thread id is not a boundary proof". Both become false the moment the guard becomes thread-identity based. Gate them on single-line tokens that exist *today* on one line (`SynchronizationContext comparison after a throw` on line 388, `when UiSyncContext is null` on line 383, `a thread id is not a boundary proof` on line 414) so the zero-hit condition is false-before/true-after rather than vacuous. + +3. **Do not gate on zero occurrences of `SynchronizationContext.Current`** in the same file where a later task must write remarks explaining the dispatcher context. The gate and the required prose collide. Gate the narrower `ReferenceEquals(SynchronizationContext.Current` instead. A stronger structural gate is available and cheap: after the fix the file names no unqualified `SynchronizationContext`, so `using System.Threading;` must be removed, and a `Select-String -SimpleMatch 'using System.Threading;'` zero-match over that one file proves it (it does not match `using System.Threading.Tasks;`). + +3b. **A "succeeds under a null ambient context" test is UNSATISFIABLE for `InitializeBreadcrumbPipeline`, guard or no guard.** `ItemViewer.Breadcrumb.cs:80` calls `BreadcrumbUiDispatcher.CaptureCurrent()` unconditionally on the first-time path, and `BreadcrumbUiDispatcher.cs:44-50` throws `InvalidOperationException` when `SynchronizationContext.Current` is null — independently of `ThrowIfOffUiBoundary`. Two #781 tests were first specified in exactly that shape and would have blocked execution at the first `[expect-fail]` verification. The witness must be a **repeat call with the same provider reference**, which returns through the already-initialized early return at `:60-72` and never reaches `:80`. The same trap governs every worker-thread case expected NOT to throw, because a worker thread's ambient context is null — including the `_uiDispatcher`-nulled null-owner test in item 5. General rule: when a guard fix loosens a precondition, enumerate every other fail-fast on the path to the observable outcome before asserting success. + +4. **`QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs` is 480 lines** (8 test methods; the `481` figure in an earlier draft of this note was off by one, and line 245 is the blank separator after the deleted block). Replacement tests must go in a NEW file (`QuickFiler.Test.csproj` needs an explicit ``; the project is legacy `packages.config` and its item list is insertion-ordered, not alphabetical). The old file only loses the two obsolete D4 tests at lines 152-244. Do not assert an exact post-deletion line count: the deletion leaves two adjacent blank lines that CSharpier may collapse, so an exact figure is unsatisfiable in one of the two orderings — assert a decrease instead. + +5. **The two ambient-null harnesses are same-thread, not cross-thread.** `BreadcrumbSelectorToggleUiBoundaryTests.InvokeAmbientNull` (lines 325-337) only swaps the ambient context. So does the #475 test `ConfigureBreadcrumbDropDown_SeededLifecycleNullUiContext_DoesNotThrow`, which nulls `_context` reflectively — after a dispatcher-based guard it exercises the `CheckAccess()`-true path, NOT the null-owner escape. Citing it as null-owner branch evidence is false. Add a test that nulls `_uiDispatcher` if that branch needs covering. + +6. **No test in `QuickFiler.Test` calls a guarded member from a `Task.Run` worker** (multiline search for `Task.Run` within 200 chars of the four guarded member names returns zero). The pump-host tests marshal every guarded call through `host.InvokeAsync` on the constructing thread. So a thread-identity guard breaks nothing beyond the two D4 tests being replaced. Run that search before assuming a blast radius. + +7. **`Dispatcher.CurrentDispatcher.Invoke(Action)` runs at `DispatcherPriority.Send` inline on the same thread and installs a `DispatcherSynchronizationContext` for the callback** — no message pump needed, which makes the production-shape regression test deterministic. Require the test to assert, as an arrange precondition, that the captured context is not reference-equal to the ambient one at call time, so it cannot pass vacuously if that behavior ever changes. + +8. **Never halt a plan on a pre-existing repository coverage floor.** The first draft stopped before Phase 1 when `Assert-CoberturaLineCoverageThreshold` threw on the baseline. That figure is pre-existing, and a change whose lines are outside the denominator (item 1) cannot move it in either direction, so the halt made a blocker-severity fix unexecutable for an unrelated condition. Record a `BASELINE_FLOOR: MET | NOT MET` line and continue; the operative gate is the no-regression comparison. Mechanically: put the threshold call **last** in its script block and wrap it in `try`/`catch`, because it throws a terminating error and would otherwise discard the six root attribute values the task exists to record. + +9. **The plan path can have a concurrent writer.** Two planner instances wrote this same `plan..md` in one cycle; `Write` failed twice with "file has been modified since read". Under the Plan-Path Continuity Contract the correct response is to re-read, review the concurrent text adversarially, and apply targeted `Edit` corrections — never overwrite. Re-check the whole document after every edit batch, because the other writer may also have changed prose your edit depends on. + +10. **`"/p:Platform=Any CPU"` is a SOLUTION-level alias and fails a PROJECT-file build.** `QuickFiler.Test/QuickFiler.Test.csproj` sets `AnyCPU` (line 12) and defines `OutputPath` only under `Debug|AnyCPU`, `Release|AnyCPU`, `Debug|x86`, `Release|x86` (lines 32, 41, 49, 53). A `msbuild .csproj ... "/p:Platform=Any CPU"` invocation matches no property group and fails with `The BaseOutputPath/OutputPath property is not set`. Use `/p:Platform=AnyCPU` (no space) for project-file builds and keep `"/p:Platform=Any CPU"` for `TaskMaster.sln`. Copying the CLAUDE.md solution command onto a project file is the trap. + +11. **`git diff ...HEAD` cannot observe an uncommitted plan.** The three-dot form compares two commits and never reads the working tree, so in a plan that stages but never commits it returns an empty list however the executor edits the files — an unfalsifiable scope gate. Use the two-dot `git diff -- ` form (base commit against the working tree) plus a `git add --intent-to-add` companion so a newly created file is visible, plus a `git status --porcelain --untracked-files=all` span. If the plan also needs "nothing inherited from the branch", add a separate commit-to-commit `git diff --name-only ..HEAD -- ` and gate on its emptiness rather than asserting the branch's commit contents in prose. + +12. **Cobertura root `lines-covered`/`lines-valid` are reproduced by NEITHER node axis.** `Get-CoberturaClassLineSummary` (`Invoke-MSTestWithCoverage.Helpers.ps1:193-232`) merges `./lines/line` AND `./methods/method/lines/line` keyed by line number, keeping the maximum `hits`.

That is the right +mechanism for the reported defect: every production `ItemViewer` is built inside a WPF dispatcher +operation, which installs a `DispatcherSynchronizationContext` for the duration of the callback, so +the captured context is never the UI thread's ambient context again and the old comparison rejected +every legitimate call. + +The implementation is in fact stronger than its own stated rationale. `Dispatcher.CheckAccess()` +compares `Thread` object references, not managed thread ids, so it is immune to id recycling +entirely — a point the rewritten documentation argues around rather than states (CR-4). + +Test quality is high. The new class reproduces the exact production construction shape, asserts +non-vacuity explicitly before acting, restores every ambient-context substitution in a `finally`, +and uses no sleeps, timers, or temporary files. The RED-first claim was independently reproduced by +this review: restoring the pre-fix production file yields 5 failures out of 7, matching the +executor's artifact test by test. + +**Blocking findings: 0.** Seven findings are recorded, one Medium and the rest Low or +Informational. None of them justifies withholding the PR. Two are defects in the executor's +evidence prose rather than in shipped code (CR-1, CR-2), one is a residual promotion obligation +(CR-8). + +## Findings Table + +| Severity | File | Location | Finding | Recommendation | Rationale | Evidence | +|---|---|---|---|---|---|---| +| Medium | `docs/features/.../evidence/qa-gates/coverage-delta.2026-09-05T10-49.md` | "The two-line difference in `lines-covered`" paragraph | The artifact attributes the -2 `lines-covered` movement to the two deleted D4 tests in `QuickFiler.Test`.

Both are individually defensible — `BreadcrumbUiDispatcher` accepts a currently executing dispatcher callback first and always posts through its captured context, and its fallback identity test uses a managed id rather than a `Thread` reference — but the pairing is a maintenance hazard. | Add one cross-reference sentence to each `` explaining why the two guards legitimately differ (one proves "this is the thread that owns the control", the other proves "this callback is running on the captured posting context").

Three properties are worth recording: + +1. **The null-owner escape is preserved but re-keyed.** It previously guarded a null captured + context; it now guards a null captured dispatcher. Because `Dispatcher.CurrentDispatcher` creates + a dispatcher for the calling thread rather than returning null, a viewer that has actually run + its constructor always has a non-null owner. The escape therefore only fires for a viewer built + without running the constructor, which is exactly the `FormatterServices.GetUninitializedObject` + test shape the documentation names, and the new + `InitializeBreadcrumbPipeline_NullOwningDispatcher_DoesNotThrow` test covers it by nulling the + field through reflection while asserting the field still exists. +2. **All four guard sites benefit.** The single private method is called from + `InitializeBreadcrumbPipeline` (line 51), both `ConfigureBreadcrumbDropDown` overloads (lines 172 + and 229), and `EnsureBreadcrumbResourceOwnership` (line 389). AC2's enumeration is satisfied by + construction rather than by four separate edits. +3. **The D5 statement-order comment was correctly updated.** The comment on + `EnsureBreadcrumbResourceOwnership` previously reasoned about `UiSyncContext` being null; it now + reasons about the owning dispatcher being null, so the FIRST STATEMENT / FIRST ACTION argument it + documents remains accurate after the swap. + +### Test design + +The strongest element of the new class is the non-vacuity assertion in the flagship test: + +``` +ReferenceEquals(viewer.UiSyncContext, SynchronizationContext.Current) + .Should() + .BeFalse( + "the dispatcher operation must have captured a context that is not the " + + "thread's ambient context, or this test would pass vacuously" + ); +``` + +This makes the test self-policing: if a future runtime change made the dispatcher reuse the ambient +context, the test would fail loudly rather than silently stop discriminating. That is the pattern +this repository's review history repeatedly asks for and it was applied here without prompting. + +The two tests that use a repeat-call-with-the-same-provider shape both carry a `` +explaining that the shape is required, not stylistic: a first-time initialization reaches +`BreadcrumbUiDispatcher.CaptureCurrent()`, which throws under a null ambient context regardless of +the guard, so only a call that returns through the already-initialized early return can witness the +case under test. The remarks also state why the shape still discriminates. This is the correct level +of documentation for a non-obvious test construction. + +### Deletion of the two D4 tests + +Removing `InitializeBreadcrumbPipeline_AmbientContextNull_ThrowsBoundaryDiagnostic` and +`InitializeBreadcrumbPipeline_DifferentNonNullContext_ThrowsBoundaryDiagnostic` is correct rather +than a coverage retreat: both asserted the defective behaviour directly, so retaining them would +require them to fail. Their replacements invert the expectation for the same two ambient shapes +(`_OwningThreadNullAmbientContext_DoesNotThrow` and +`_OwningThreadDifferentPlainContext_DoesNotThrow`) and add the dispatcher-operation shape that +neither original covered. Net coverage of the guard's contract increased. + +The reviewer re-ran the six retained lifecycle tests, which cover the issue #488 D3 (second-provider +fail-fast) and D5 (disposal) behaviours AC5 requires be left intact, and all six pass. + +### Scope discipline + +The C# write set is exactly the four paths AC7 permits. The reviewer confirmed independently with +`git diff --numstat` that zero paths under `QuickFiler/Controllers/` appear in the branch diff, so +`QfcCollectionController.LoadSecondaryAsync`, `QfcItemController.AssignFolderComboBox`, and +`QfcItemController.EnsureBreadcrumbPipeline` are untouched, as AC7 requires. + +The nine `.claude/agent-memory/**` files were reviewed rather than excluded. They are well-formed +learning entries with correct frontmatter (`name`, `description`, `metadata.type`) and matching +one-line `MEMORY.md` index pointers, and their content is accurate against what this review observed +(notably the `[ExcludeFromCodeCoverage]`-on-partial-class entry and the Cobertura package-rollup +entry).

The rewritten +`ThrowIfOffUiBoundary` reads that dispatcher, returns without effect when it is null, and +otherwise throws `InvalidOperationException` when `CheckAccess()` is false. The `UiSyncContext` +property and every other member are left in place. + +## Constraint 3 — Prohibition on touching the controllers + +`QuickFiler/Controllers/**` must not be edited. AC7 names +`QuickFiler/Controllers/QfcCollectionController.cs`, +`QuickFiler/Controllers/QfcItemController.FolderHandling.cs`, and +`QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` explicitly; none of the three, and no +other file under that directory, may appear in the diff.

Specifically prohibited by token: `Thread.Sleep`, +`Task.Delay`, `Path.GetTempFileName`, `InvokeAsync`, and `PushFrame`. `Dispatcher.Run` is also +prohibited. Only the same-thread `Dispatcher.Invoke(Action)` fast path is used, which runs the +callback inline at `DispatcherPriority.Send` and needs no pump; an awaited `DispatcherOperation` +against a dispatcher that is never pumped would not complete and would hang the run instead of +failing it. Injected operations are built from an owner-thread-only boundary +(`BreadcrumbUiDispatcher.CreateForCurrentThreadTests()`) or the drainable-context shape already +present in `ItemViewerBreadcrumbLifecycleRegressionTests`, so no posted work escapes the test +thread.

P1-T4's acceptance "the msbuild invocation exits 0" is unsatisfiable as written.

The union is required rather than the P0-T8 observation alone: defining the set by one observation would fail P2-T6 on a pre-existing intermittent condition in `UtilitiesCS.Test` that this `QuickFiler` change cannot affect, which is the same unexecutability the version 1.2 correction removed from P0-T9.

Do **not** record the output of `git rev-parse --show-toplevel` verbatim: that value is an absolute host path containing the operating-system account name, and this repository forbids an absolute host path in any tracked artifact — the same rule correction 7 of this plan applied to the execution-location decision.

A hand-written count over `./classes/class/lines/line` does not reproduce it: `Get-CoberturaClassLineSummary` (`scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 193 through 232) merges `./lines/line` and `./methods/method/lines/line` into a map keyed by line number and keeps the maximum `hits` across the two views, so a line present only in the method view, or covered only there, is counted by the root attributes and missed by a class-direct count. +> +> ```powershell +> . .\scripts\vscode\Invoke-MSTestWithCoverage.Helpers.ps1 +> [xml]$cov = Get-Content -LiteralPath '.\coverage\baseline-781.cobertura.xml' -Raw -Encoding UTF8 +> $sb = [System.Text.StringBuilder]::new() +> [void]$sb.AppendLine('') +> $tc = 0; $tm = 0; $tbc = 0; $tbm = 0 +> foreach ($pkg in @($cov.SelectNodes('/coverage/packages/package'))) { +> $s = Get-CoberturaPackageLineSummary -PackageNode $pkg +> $lc = [int]$s.LinesCovered; $lm = [int]$s.LinesValid - $lc +> $bc = [int]$s.BranchesCovered; $bm = [int]$s.BranchesValid - $bc +> $tc += $lc; $tm += $lm; $tbc += $bc; $tbm += $bm +> [void]$sb.AppendLine(" ") +> } +> [void]$sb.AppendLine('') +> Set-Content -LiteralPath '.\docs\features\active\2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781\evidence\baseline\coverage-baseline.jacoco.2026-09-05T10-49.xml' -Value $sb.ToString() -Encoding UTF8 +> Write-Output "derived lines-covered=$tc lines-valid=$($tc + $tm) branches-covered=$tbc branches-valid=$($tbc + $tbm)" +> ``` +> +> `Invoke-MSTestWithCoverage.Helpers.ps1` dot-sources `Invoke-MSTestWithCoverage.PackageRate.ps1`, which declares `Get-CoberturaPackageLineSummary`, so the single dot-source above resolves it.

A grep of the changed file for +`ReferenceEquals(SynchronizationContext.Current` returns zero matches, and `using System.Threading;` +has been removed from the file. `Dispatcher.CheckAccess()` compares `Thread` object references, +which is a stricter form of owner-thread identity than the id comparison the AC permits as one +option. + +### AC2 — guarded members succeed on the owning thread under any ambient context + +**PASS.** All four guard sites route through the single private method: line 51 +(`InitializeBreadcrumbPipeline`), lines 172 and 229 (both `ConfigureBreadcrumbDropDown` overloads), +and line 389 (`EnsureBreadcrumbResourceOwnership`). The last is reached from +`InitializeBreadcrumbPipeline` through `EnsureBreadcrumbLifecycle` (line 361), so the owning-thread +tests exercise it. + +All three ambient shapes the AC enumerates are covered by a passing test that the reviewer executed +in this session: + +| Ambient shape at the call site | Test | Result | +|---|---|---| +| `DispatcherSynchronizationContext` from a WPF dispatcher operation | `InitializeBreadcrumbPipeline_ConstructedInsideDispatcherOperation_...` and `ConfigureBreadcrumbDropDown_OwningThreadInsideDispatcherOperation_DoesNotThrow` | Passed | +| null | `InitializeBreadcrumbPipeline_OwningThreadNullAmbientContext_DoesNotThrow` | Passed | +| a different plain `SynchronizationContext` instance | `InitializeBreadcrumbPipeline_OwningThreadDifferentPlainContext_DoesNotThrow` | Passed | + +### AC3 — cross-thread call still throws `InvalidOperationException` naming the operation + +**PASS.** The `throw` retains `InvalidOperationException` and the message still interpolates +`{operation}`, which every call site supplies via `nameof(...)`. Two tests assert the contract +directly, each with `.Where(error => error.Message.Contains(""))` and an explicit +`.Which.Should().NotBeOfType()`: +`InitializeBreadcrumbPipeline_WorkerThread_ThrowsBoundaryDiagnostic` and +`ConfigureBreadcrumbDropDown_WorkerThread_ThrowsBoundaryDiagnostic`. Both passed in the reviewer's +run, and both also passed against the pre-fix guard, which confirms the fail-fast contract was +preserved rather than weakened by the change. + +### AC4 — deterministic regression test reproducing the production shape + +**PASS.** `InitializeBreadcrumbPipeline_ConstructedInsideDispatcherOperation_SucceedsUnderDifferentAmbientContext` +installs a plain `SynchronizationContext`, constructs the viewer inside +`Dispatcher.CurrentDispatcher.Invoke((Action)(...))`, and then calls +`InitializeBreadcrumbPipeline` on the same thread outside that operation. It asserts non-vacuity +before acting, by requiring that the viewer's captured context is not reference-equal to the ambient +context. + +Determinism requirements are met: no sleep, timer, wall-clock wait, or temporary file appears in the +file; the same-thread `Dispatcher.Invoke(Action)` fast path runs the callback inline at +`DispatcherPriority.Send` and needs no message pump; the ambient context is restored in a `finally`. +The reviewer observed the test fail against the pre-fix guard and pass against the fixed guard. + +### AC5 — old reference-comparison tests replaced; #488 D3 and D5 behaviours intact + +**PASS.** Both named tests are deleted from +`QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs` +(`InitializeBreadcrumbPipeline_AmbientContextNull_ThrowsBoundaryDiagnostic` and +`InitializeBreadcrumbPipeline_DifferentNonNullContext_ThrowsBoundaryDiagnostic`, 94 lines removed), +and the suite now asserts the thread-identity contract through the new class. + +The D3 and D5 tests are unchanged and were re-executed by the reviewer: +`InitializeBreadcrumbPipeline_SecondDifferentProvider_ThrowsInvalidOperationException` (D3) and +`InitializeBreadcrumbPipeline_AfterViewerDisposed_ThrowsObjectDisposedException` (D5) both Passed, +as did the four other retained tests in the class. Removing the two deleted tests is correct rather +than a coverage retreat: both asserted the defective behaviour and could not have been retained +without failing. + +### AC6 — XML documentation states the thread-identity contract and why context equality was unsuitable + +**PASS, with a documentation-accuracy note.** The rewritten `` states that ownership is +proved through `Dispatcher.CheckAccess()` on the constructor-captured dispatcher, and explains why +the previous test was unsuitable: a WPF dispatcher operation installs a +`DispatcherSynchronizationContext` for the duration of its callback, so a viewer constructed inside +one captures a context that is never the UI thread's ambient context again. Both clauses the AC +requires are present. The `EnsureBreadcrumbResourceOwnership` statement-order comment was updated in +the same commit and remains accurate: it now reasons about the owning dispatcher being null rather +than about `UiSyncContext` being null, preserving the FIRST STATEMENT / FIRST ACTION argument it +documents. + +Note, recorded as code-review finding CR-4 and not affecting this verdict: the supporting sentence +"Managed thread ids are unique among live threads" describes a mechanism the code does not use. +`Dispatcher.CheckAccess()` compares `Thread` object references, so id recycling is not a +consideration at all. The AC's required content is present; the supporting argument understates the +guard. + +### AC7 — scope limited to `QuickFiler/Viewers/ItemViewer*.cs` and their tests + +**PASS.** Independently verified by the reviewer with +`git diff --numstat a007f72e..4f74aa39`, not by reading the executor's scope-boundary artifact. The +C# change surface is exactly four paths, listed in the Scope and Baseline section above. Zero paths +under `QuickFiler/Controllers/` appear in the branch diff, so `QfcCollectionController.cs`, +`QfcItemController.FolderHandling.cs`, and `QfcItemController.ViewerSetup.cs` — the three files AC7 +names explicitly — are unchanged. + +One non-code path outside the write set is present in the branch: the deletion of the tracked, +gitignore-matched `artifacts/orchestration/orchestrator-state.json`. It is not a source or test file +and does not bear on AC7's subject, which is the fix's code scope; it is recorded separately as +policy-audit finding F5 and code-review finding CR-6. + +### AC8 — full C# toolchain in one consecutive pass, >= 90% new-code line coverage, canonical coverage artifact produced + +**PASS, with a recorded deviation on the coverage clause.** + +Toolchain clause — satisfied and independently corroborated: + +| Stage | Command | Exit | +|---|---|---| +| Format | `dotnet tool run csharpier check .` | 0, zero files needing formatting | +| Analyzers | `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` | 0, 3 warnings equal to baseline, 0 errors, 36 `csc.exe` invocations so the gate was live | +| Nullable and type check | `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true` | 0, 3 warnings equal to baseline, 0 errors, `/p:Nullable=enable` correctly omitted and `/t:Rebuild` correctly used | +| Test | `vstest.console.exe ... /EnableCodeCoverage /InIsolation` | 0; repository-wide suite 6997 of 6997 passed | + +No stage modified a file, so the four stages completed in one consecutive pass without a restart. +The reviewer re-ran the format stage over the two changed directories (exit 0) and the test stage +over the four affected classes (33 of 33 passed). + +Canonical artifact clause — satisfied. `artifacts/csharp/coverage.xml` exists, 12,732,521 bytes, +mtime 2026-09-05 17:10, Cobertura root +`line-rate="0.848316" branch-rate="0.791421" lines-covered="54920" lines-valid="64740"`. + +Coverage clause — **deviation**. No percentage exists for the changed production lines. The reviewer +independently enumerated every `` element in the baseline and post-change Cobertura documents +and found zero whose `filename` ends `ItemViewer.Breadcrumb.cs` in either.

They close the open questions raised against version 1.0. + +1. **Execution location.** Execution happens in the main checkout at the repository root (referred to below as ``; no absolute host path is recorded in this tracked document), which is on branch `bug/breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781` at HEAD `ef0b5253`. The harness snapshot naming `chore/update-dependencies` predates that checkout. P0-T3 still records the observed branch and still reports `BRANCH MISMATCH` if it differs, because that task is the plan's own verification of this decision rather than a restatement of it. +2. **Base ref.** A local `main` exists at `a007f72e` and equals `origin/main`. `BASE_REF` is `main`. P0-T3 still records `BASE_REF:` so P1-T10 reads a value observed at execution time. +3. **Coverage of the excluded class.** The orchestrator accepts the P2-T7 `CHANGED-CODE COVERAGE: NOT MEASURABLE` determination as satisfying AC8's new-code clause. The class-level `[ExcludeFromCodeCoverage]` on `ItemViewer` is the ratified WinForms UserControl exemption under CLAUDE.md UT2(b), and removing it is out of scope for this issue. +4. **Canonical artifact format.** `artifacts/csharp/coverage.xml` stays a verbatim Cobertura copy, as P2-T8 specifies. Do not write JaCoCo to that path. The feature-review-workflow skill defines the artifact through `dotnet test --collect:"XPlat Code Coverage"`, which emits Cobertura. The consequence that `.claude/hooks/validate-feature-review-coverage.ps1` parses JaCoCo `` elements and therefore computes null on this file is recorded by the orchestrator as an upstream item and is not addressed here. +5. **Run cost.** Both repository-wide runs, P0-T8 and P2-T6, are accepted as planned, including the four shell-icon class exclusions. + +## Corrections Applied In Version 1.2 (planner adversarial self-review) + +Each item below was found by re-deriving a citation against the working tree and is recorded so a reviewer can check the correction rather than rediscover the defect. + +1. **Two tests were unsatisfiable as specified.** `InitializeBreadcrumbPipeline_OwningThreadNullAmbientContext_DoesNotThrow` and `InitializeBreadcrumbPipeline_NullOwningDispatcher_DoesNotThrow` both asserted that a first-time pipeline initialization succeeds under a null ambient synchronization context. `ItemViewer.Breadcrumb.cs` line 80 calls `BreadcrumbUiDispatcher.CaptureCurrent()`, which throws under a null ambient context independently of the guard, so neither test could have passed after the fix. Both are now specified as repeat calls with the same provider reference, which return through the already-initialized early return. New fact 16 records the mechanism. +2. **A halt on a pre-existing coverage figure was removed.** P0-T9 previously stopped the plan before Phase 1 when the repository-wide baseline line-rate was below 80 percent. That figure is pre-existing and this change cannot move it, so the halt would have made a blocker-severity fix unexecutable for an unrelated condition. P0-T9 now records `BASELINE_FLOOR:` and continues, and the threshold call is the last statement of its block and wrapped in `try`/`catch` so a throw no longer discards the six numeric values the task exists to record. +3. **Line-count citation corrected.** `ItemViewerBreadcrumbLifecycleRegressionTests.cs` is 480 lines, not 481. +4. **Phase 0 artifact name corrected.** The policy-read artifact is `phase0-instructions-read.md`, the exact name `.claude/skills/atomic-plan-contract/SKILL.md` requires, with no timestamp suffix. +5. **A stale sibling comment was brought into scope.** `SetViewerSyncContext` in the regression test file documents that nulling `_context` makes the affinity guard inert. The guard change falsifies that. P1-T8 now corrects it and gates on the single-line literal. +6. **An exact-count gate was relaxed to a lower bound.** P1-T5 demanded exactly one occurrence of `CheckAccess()`, which the P1-T6 documentation rewrite could legitimately push to two. It is now a lower bound, and the justification for the removed `using System.Threading;` no longer overclaims. +7. **An absolute host path was removed** from the execution-location decision, per the repository rule against embedding host paths in tracked documents. +8. **Test-support gaps were closed.** P1-T2 now names the stub `IBreadcrumbDropDownHost` the two `ConfigureBreadcrumbDropDown` tests require, names the owner-thread-only operations seam (new fact 17), and forbids `InvokeAsync` and `PushFrame` by token so the dispatcher tests cannot be rewritten into a shape that hangs the run instead of failing it. +9. **The regression-risk claim was given an argument.** Fact 8 previously rested on an enumeration of call sites. It now also carries the equivalence argument that bounds which shapes the old guard admitted and the new guard rejects. + +## Corrections Applied In Version 1.3 (executor preflight round 1) + +Round 1 returned `PREFLIGHT: REVISIONS REQUIRED` with eight defects and three advisories, recorded verbatim at `FEATURE/evidence/other/preflight-round1-revisions.2026-09-05T19-59.md`. All fifteen deltas are applied. Every citation each delta relies on was re-derived against the working tree before it was applied. + +1. **D1 — P1-T4 and P1-T9 used a platform value the project file rejects.** Both project-file builds now pass `/p:Platform=AnyCPU`. Re-derived: `QuickFiler.Test/QuickFiler.Test.csproj` declares `AnyCPU` at line 12 and defines `OutputPath` only under `Debug|AnyCPU` (line 32), `Release|AnyCPU` (line 41), `Debug|x86` (line 49) and `Release|x86` (line 53). The solution-level `Any CPU` alias in P0-T6, P0-T7, P2-T3 and P2-T4 is unchanged and must stay. +2. **D2 — P1-T10's diff span observed nothing.** The three-dot `main...HEAD` form compares two commits and never reads the working tree, so with no commit in this plan it reported an empty list whatever the executor edited. P1-T10 now uses the two-dot `git diff --name-status main -- ` form against the working tree, retains the `--intent-to-add` and porcelain companions, and adds a fourth invocation recorded under `INHERITED PATHS:`. +3. **D3 — P0-T3 wrote an absolute host path into a tracked artifact.** `git rev-parse --show-toplevel` is no longer recorded verbatim; the task records `TOPLEVEL CONTAINS FEATURE:` and `TOPLEVEL LEAF:` instead, and its acceptance now requires the artifact to contain no absolute filesystem path. +4. **D4 — P2-T13 staged before P2-T14 created its artifact.** P2-T14 now re-stages the feature folder after writing the handoff record and gates on a porcelain output carrying no `??` path. +5. **D5 — `BASELINE_FAILURE_SET` could not absorb the flaky test it was written for.** The set is now the union of the P0-T8 observation and the known-flaky name, and P0-T8 records that name under `BASELINE_FAILURE_SET:` whether or not it was observed to fail. +6. **D6 — P0-T10 and P2-T8 asserted an equality no available node axis produces.** Both now derive per-package counters from the repository's own `Get-CoberturaPackageLineSummary`, which is the same helper `Get-CoberturaCoverageSummary` sums into the root attributes, so the identity holds by construction. Re-derived: `Invoke-MSTestWithCoverage.Helpers.ps1` line 120 calls `Get-CoberturaPackageLineSummary -PackageNode` and lines 121 through 124 sum `.LinesValid`, `.LinesCovered`, `.BranchesValid` and `.BranchesCovered`; `Get-CoberturaClassLineSummary` merges `./lines/line` and `./methods/method/lines/line` at lines 193 and 194 and keeps the maximum `hits` at lines 216 through 218; `Invoke-MSTestWithCoverage.PackageRate.ps1` declares the helper at line 3, takes `[System.Xml.XmlElement]$PackageNode` at line 41, returns those four properties at lines 60 through 63, and calls `Set-StrictMode -Version Latest` at line 1; `Helpers.ps1` dot-sources it at line 3. Fact 14 is corrected accordingly. +7. **D7 — P1-T11's evidence citation contradicted the condition it cited.** It now states the lower bound that P1-T5 actually carries. +8. **D8 — the Write Set annotation contradicted P1-T8.** The regression test file is annotated as two test-method deletions plus one comment-clause correction. +9. **A1 — P2-T5 carried no long-run guidance.** The stall behaviour, the two-sample CPU-time check, the scoped termination, and the statement that an unchanged rerun is not a toolchain-loop restart are now in the task text. +10. **A2 — P2-T13's ignore rationale was inaccurate.** The acceptance now attributes the result to the pathspec-scoped `git add` rather than to `.gitignore`, and records that the ignore rules apply to untracked paths only. +11. **Conventions — shell form.** A bullet records that every command is issued as a `git` invocation or from inside a `pwsh -NoProfile` process, so the recorded `Command:` values and the permitted shell forms agree. + +**One delta was corrected against the tree before it was applied.** Delta 10 as written asserted that "the single commit between the base ref and `HEAD` touches only `docs/`". That claim depends on commit contents, and no git tool was available in this planning session, so it could not be re-derived. Asserting an unverified fact in the plan is not permitted, so the clause was replaced by an executor-verified observation that establishes the same operative consequence and is strictly stronger: P1-T10 now runs `git diff --name-only main..HEAD` over the same two pathspecs, records the result under the literal heading `INHERITED PATHS:`, and requires that heading to list no path. If it does list a path, the task reports it and subtracts it from the union rather than proceeding on an assumption. Every other citation in every other delta was re-derived and applied as written. + +**Advisory A3** requires no plan change. The `PLANNER-INTERNAL-REVIEW: PASS` record and the `SELF-REVIEW: RE-DERIVED THIS PASS` enumeration belong to the planner-to-executor handoff, not to the plan file; the orchestrator relays them with the preflight delegation. + +**Commit responsibility.** This plan stages but never commits. The orchestrator commits through the commit-message agent per the orchestrate skill. P2-T13 ends with a staged, uncommitted tree. **Fail-closed evidence rule:** Include explicit baseline artifact tasks, final-QA artifact tasks, and coverage-comparison tasks for each in-scope language when policy requires coverage. If any required baseline artifact, QA artifact, or coverage-comparison artifact is missing, the audit verdict must be BLOCKED or INCOMPLETE, never PASS. **Evidence accounting rule:** Record the expected artifact path or location in each evidence-producing task. Do not mark evidence-backed work complete without the artifact. +--- + +## Conventions Used By This Plan + +- `FEATURE` denotes `docs/features/active/2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781`. +- Every evidence artifact this plan produces is written under `FEATURE/evidence//` with `` one of `baseline`, `regression-testing`, `qa-gates`, `issue-updates`, `other`. No evidence is written to `artifacts/baselines/`, `artifacts/baseline/`, `artifacts/qa/`, `artifacts/qa-gates/`, `artifacts/coverage/`, `artifacts/evidence/`, or `artifacts/regression-testing/`. +- `artifacts/csharp/coverage.xml` is a review-tooling input, not evidence. It is git-ignored (`.gitignore` line 57 ignores `artifacts/`) and is produced only so `.claude/hooks/validate-feature-review-coverage.ps1` and the feature reviewer have a current C# coverage document at the canonical path AC8 names. +- All artifact filenames carry the fixed suffix `2026-09-05T10-49`, which is this plan's timestamp, with one deliberate exception: `FEATURE/evidence/baseline/phase0-instructions-read.md` carries no suffix, because `.claude/skills/atomic-plan-contract/SKILL.md` names that filename exactly and a suffixed variant would not satisfy its Phase 0 evidence check. The `Timestamp:` field **inside** each artifact records the actual execution time in `yyyy-MM-ddTHH-mm` form. Baseline and final-QC artifacts never collide because they live in different `evidence//` folders. +- Every command-step artifact carries `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:`. Test-step artifacts additionally carry numeric coverage headline values in `Output Summary:`. +- `BASELINE_FAILURE_SET` denotes the union of two sets: the exact set of fully-qualified test names recorded as failed by task P0-T8, and the single known-flaky name `DictionaryExtensions_Tests.TryAddValuesAsync_UpdatesExistingValue` (issue #780), which fails only intermittently under a parallel coverage run and may therefore pass in P0-T8 and fail in P2-T6. The union is required rather than the P0-T8 observation alone: defining the set by one observation would fail P2-T6 on a pre-existing intermittent condition in `UtilitiesCS.Test` that this `QuickFiler` change cannot affect, which is the same unexecutability the version 1.2 correction removed from P0-T9. Repository-wide zero-failure assertions are not used for the same reason. +- Every command this plan runs is issued either as a `git` invocation or from inside a `pwsh -NoProfile -Command` process (or `pwsh -NoProfile -File` for the P0-T8 script). `dotnet`, `msbuild`, `vstest.console.exe` and `dotnet-coverage` are invoked from within that `pwsh` process rather than directly, so the shell forms this workspace permits and the `Command:` values recorded in the evidence artifacts agree. +- Raw `.trx` files are never copied into `FEATURE/evidence/`. A `.trx` carries `runUser` and `computerName` host tokens. TRX output stays under `TestResults\`, which `.gitignore` line 39 (`[Tt]est[Rr]esult*/`) already ignores; evidence artifacts record only counts and test names. +- Raw Cobertura reports are never staged and never committed. The only coverage evidence this plan stages is the package-level JaCoCo projection, produced by P0-T10 for the baseline and by P2-T8 for the final pass. Raw Cobertura stays under `coverage\`, which `.gitignore` line 144 (`coverage/*`) ignores. A full-repository Cobertura document for this repository is roughly 10 MB and 187,000 lines, which is why the compact projection is what enters the feature folder. + +## Write Set (exhaustive; anything outside this set is out of scope) + +Production: + +- `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs` + +Tests and test build configuration: + +- `QuickFiler.Test/Viewers/ItemViewerBreadcrumbThreadAffinityTests.cs` (new file) +- `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs` (two test-method deletions plus one comment-clause correction in the `SetViewerSyncContext` ``; no other edit) +- `QuickFiler.Test/QuickFiler.Test.csproj` (one added `` line) + +Documentation and evidence: + +- `FEATURE/issue.md` (AC checkbox state only) +- `FEATURE/plan.2026-09-05T10-49.md` (task checkbox state only) +- `FEATURE/evidence/**` + +Local, git-ignored, never staged: `coverage/**`, `TestResults/**`, `artifacts/csharp/coverage.xml`, and the throwaway session script named in P0-T8. + +This plan stages the Write Set in P2-T13 and does not commit it.

The XML documentation for the guard begins at line 406, the method `ThrowIfOffUiBoundary` is declared at line 420, its `SynchronizationContext owning = UiSyncContext;` capture is line 422, its `ReferenceEquals(SynchronizationContext.Current, owning)` test is line 428, and the method closes at line 436. +2. The same file's `EnsureBreadcrumbResourceOwnership` statement-order comment occupies lines 380 through 388 and ends with the sentence that names a `SynchronizationContext` comparison. +3. The file's using block is lines 1 through 9 and contains `using System.Threading;` at line 4. After the fix, `SynchronizationContext` is no longer referenced anywhere in the file, so that using becomes unused. `System.Windows.Threading` is **not** in the using block and must be added for the `Dispatcher` type. +4. `QuickFiler/Viewers/ItemViewer.cs` line 23 through 29 is the constructor. It captures `_context = SynchronizationContext.Current` (line 26) and `_uiDispatcher = Dispatcher.CurrentDispatcher` (line 27). The `Dispatcher` is exposed publicly as `UiDispatcher` (lines 64 through 68). +5. `QuickFiler/Viewers/ItemViewer.cs` line 20 carries `[ExcludeFromCodeCoverage]` on the `ItemViewer` partial class declaration. The attribute applies to the whole type, including the members declared in `ItemViewer.Breadcrumb.cs`. This is confirmed empirically against `artifacts/csharp/final-coverage.cobertura.xml`, a full coverage document produced by a previous feature's run and still on disk because `artifacts/` is git-ignored: a search of that document returns zero occurrences of `ItemViewer.Breadcrumb.cs` and zero occurrences of `name="QuickFiler.ItemViewer"`, while returning 20 occurrences of the substring `ItemViewer` from unrelated identifiers such as `ItemViewerQueue` and `BreadcrumbItemViewerLifecycleCoordinator`. The prior document is corroborating evidence only; P0-T9 measures the same property on this feature's own baseline run and is what the plan gates on. The changed production lines are therefore outside the coverage denominator and cannot produce a measured percentage. AC8's new-code coverage clause is handled by P2-T7 on that basis. +6. `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs` is 480 lines and declares 8 `[TestMethod]` members. The two obsolete D4 tests, with their XML documentation, occupy lines 152 through 244; line 245 is the blank separator before the D5 test's documentation at line 246. Adding the new tests to this file would take it past the 500-line ceiling, so the new tests go in a new file. +7. `QuickFiler.Test/QuickFiler.Test.csproj` uses explicit `` items (legacy `packages.config` project). `Viewers\ItemViewerBreadcrumbLifecycleRegressionTests.cs` is wired at line 92. The project already references `WindowsBase` (line 460), so `System.Windows.Threading.Dispatcher` is available to the test assembly. +8. No test in `QuickFiler.Test` calls a guarded member from a `Task.Run` worker. A multiline search for `Task.Run` followed within 200 characters by `InitializeBreadcrumbPipeline`, `ConfigureBreadcrumbDropDown`, `EnsureBreadcrumbResourceOwnership`, or `InitializeWebViewAsync` returns zero matches across the whole test project. The pump-host tests in `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs` (line 74) and `.Part3.cs` construct the viewer inside `host.InvokeAsync` and make every guarded call inside `host.InvokeAsync` on the same pump thread, so a thread-identity guard leaves them passing. The enumeration is corroborated by an argument that does not depend on it: the old guard admits a call exactly when the ambient context instance is reference-equal to the captured one, and the new guard admits a call exactly when the calling thread is the constructing thread. The only shape the old guard admitted and the new one rejects is one where the captured context instance is ambient on a **different** thread, which requires a test to install another thread's context object on the calling thread; no test in `QuickFiler.Test` does that, and the two shapes that come closest are `QfcItemController.ViewerSetupTests.ResolveControlGroups_WithHeadlessItemViewer_PopulatesConcreteControlCollections` (line 388, which constructs and calls on the one thread) and `...ResolveControlGroupsAsync_ThroughThePumpHost_PopulatesTipsAndControlGroups` (line 426, which constructs on the pump and reaches no guarded member; `ResolveControlGroups` and `ResolveControlGroupsAsync` are not guarded). P2-T5 and P2-T6 are the safety net for the whole assembly regardless. +9. `QuickFiler.Test/Helper Classes/QfcThemeHelperTests.cs` line 249 and `QuickFiler.Test/Helper Classes/ViewerQueueStaticWrapperTests.cs` lines 97, 128, 208, 280 build an `ItemViewer` through `FormatterServices.GetUninitializedObject`, so `_uiDispatcher` is null on those instances. Neither file calls a guarded member, but the guard must retain a null-owner escape so those shapes stay inert. +10. `QuickFiler.Test/Viewers/BreadcrumbSelectorToggleUiBoundaryTests.InvokeAmbientNull` (lines 325 through 337) sets the ambient context to null and invokes on the **same** thread. It is not a cross-thread harness. +11. The guard's exception message is asserted nowhere except by the two tests being replaced, and those assert only `error.Message.Contains("InitializeBreadcrumbPipeline")`. A repository-wide search for `must be called on the thread that owns` matches only `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs`, `FEATURE/issue.md`, and `docs/features/potential/promoted/2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers.md`. +12. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` guards its entry point with `if ($MyInvocation.InvocationName -ne '.')` at line 348, so dot-sourcing the file exposes its functions without running a test pass. Its discovery filter at line 301 already excludes `.claude\` paths. Its `Get-DotnetCoverageArgumentList` hardcodes `/TestCaseFilter:TestCategory!=LiveOutlook` at line 76 and offers no extension point, which is why the repository-wide runs in this plan issue `dotnet-coverage collect` directly with the same argument shape plus the workstation-specific hang exclusion. +13. `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` line 405 declares `ConvertTo-KoverageCoberturaXml -XmlContent -RepoRoot `. It removes non-first-party packages, rewrites filenames to repository-relative form, merges duplicate classes by filename, and recomputes the root `line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` attributes. `Assert-CoberturaLineCoverageThreshold` (`scripts/vscode/Invoke-MSTestWithCoverage.Threshold.ps1`) throws unless the recomputed root `line-rate` is at or above 0.80. +14. In this repository's Cobertura output every `` carries both a `///` tree and a duplicating class-direct `/` block (`artifacts/csharp/final-coverage.cobertura.xml` lines 7 through 46 show both for one class). Neither axis reproduces the document's root attributes, so a per-package count that must reconcile with them is computed by the repository's own `Get-CoberturaPackageLineSummary` rather than by hand: `./classes/class/lines/line` misses any line that appears only in the method view and reads a `hits` of 0 where the method view recorded a hit, and `.//lines/line` double-counts. +15. Four `UtilitiesCS.Test` classes stall a local vstest run on this workstation because of a hung Windows shell icon handler: `HelperClasses.ShellUtilities_Tests`, `HelperClasses.ShellUtilitiesStatic_Tests`, `HelperClasses.SysImageListHelperTests`, `EmailIntelligence.OSBrowser_Tests`. Every repository-wide run in this plan excludes them by `FullyQualifiedName!~` and relies on CI to cover them. + +16. **A first-time `InitializeBreadcrumbPipeline` call cannot succeed under a null ambient synchronization context, guard or no guard.** `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs` line 80 calls `BreadcrumbUiDispatcher.CaptureCurrent()` unconditionally while constructing the bridge coordinator, and `QuickFiler/Viewers/BreadcrumbUiDispatcher.cs` lines 44 through 50 show that member throwing `InvalidOperationException` when `SynchronizationContext.Current` is null. That throw is independent of `ThrowIfOffUiBoundary` and survives this change. Two consequences bind the test design and must not be "simplified" away: the AC2 null-ambient case has to be witnessed by a call that returns through the already-initialized early return at lines 60 through 72, which never reaches line 80; and any worker-thread case that is expected **not** to throw has to take that same early return, because a worker thread's ambient context is null. A test that initializes a fresh pipeline under a null ambient context and asserts success is unsatisfiable after the fix and would make the plan unexecutable. + +17. `QuickFiler/Viewers/BreadcrumbUiDispatcher.cs` lines 62 through 65 declare `internal static BreadcrumbUiDispatcher CreateForCurrentThreadTests()`, an owner-thread-only boundary that reports rather than marshals cross-thread work. `BreadcrumbPopupUiOperations` accepts a single `BreadcrumbUiDispatcher` constructor argument, as used at `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs` lines 54 through 56.

Do **not** record the output of `git rev-parse --show-toplevel` verbatim: that value is an absolute host path containing the operating-system account name, and this repository forbids an absolute host path in any tracked artifact — the same rule correction 7 of this plan applied to the execution-location decision. Record instead, under the literal heading `TOPLEVEL CONTAINS FEATURE:`, the single word `YES` or `NO`, obtained by testing whether the directory `docs/features/active/2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781` exists beneath the toplevel path, and record under the literal heading `TOPLEVEL LEAF:` only the final path segment of that toplevel path. If no local `main` ref exists in that worktree, use `origin/main` instead and record in the artifact, under the literal heading `BASE_REF:`, which of the two refs was used; every later task that names `main` as a diff base uses that same recorded ref.

Acceptance, all three required: the `Output Summary:` carries all six numeric values; it carries the class count; and it carries a `BASELINE_FLOOR:` line. A `NOT MET` outcome is reported to the orchestrator as `BASELINE COVERAGE FLOOR NOT MET` and **execution continues**: the breach is pre-existing, this change adds no production line to the coverage denominator and removes none (fact 5), so it cannot move the repository figure in either direction, and the operative gate for this issue is the no-regression comparison in P2-T9. Halting a blocker-severity fix on a pre-existing repository-wide figure would make this plan unexecutable for a condition it cannot remedy. + +- [x] [P0-T10] Project the baseline Cobertura to a package-level JaCoCo summary at `FEATURE/evidence/baseline/coverage-baseline.jacoco.2026-09-05T10-49.xml`, using `pwsh -NoProfile -Command` over the block below, run from the repository root. This projection is what P2-T13 stages; the raw Cobertura is never staged. The per-package counters are produced by the repository's own `Get-CoberturaPackageLineSummary` and not by a hand-written node count, because that helper is exactly what `Get-CoberturaCoverageSummary` sums into the root attributes this task's acceptance compares against, so the identity holds by construction. A hand-written count over `./classes/class/lines/line` does not reproduce it: `Get-CoberturaClassLineSummary` (`scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 193 through 232) merges `./lines/line` and `./methods/method/lines/line` into a map keyed by line number and keeps the maximum `hits` across the two views, so a line present only in the method view, or covered only there, is counted by the root attributes and missed by a class-direct count. + + ```powershell + . .\scripts\vscode\Invoke-MSTestWithCoverage.Helpers.ps1 + [xml]$cov = Get-Content -LiteralPath '.\coverage\baseline-781.cobertura.xml' -Raw -Encoding UTF8 + $sb = [System.Text.StringBuilder]::new() + [void]$sb.AppendLine('') + $tc = 0; $tm = 0; $tbc = 0; $tbm = 0 + foreach ($pkg in @($cov.SelectNodes('/coverage/packages/package'))) { + $s = Get-CoberturaPackageLineSummary -PackageNode $pkg + $lc = [int]$s.LinesCovered; $lm = [int]$s.LinesValid - $lc + $bc = [int]$s.BranchesCovered; $bm = [int]$s.BranchesValid - $bc + $tc += $lc; $tm += $lm; $tbc += $bc; $tbm += $bm + [void]$sb.AppendLine(" ") + } + [void]$sb.AppendLine('') + Set-Content -LiteralPath '.\docs\features\active\2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781\evidence\baseline\coverage-baseline.jacoco.2026-09-05T10-49.xml' -Value $sb.ToString() -Encoding UTF8 + Write-Output "derived lines-covered=$tc lines-valid=$($tc + $tm) branches-covered=$tbc branches-valid=$($tbc + $tbm)" + ``` + + `Invoke-MSTestWithCoverage.Helpers.ps1` dot-sources `Invoke-MSTestWithCoverage.PackageRate.ps1`, which declares `Get-CoberturaPackageLineSummary`, so the single dot-source above resolves it.

The platform value is `AnyCPU` with no space, and the solution-level alias `Any CPU` used by P0-T6, P0-T7, P2-T3 and P2-T4 must not be substituted here: `QuickFiler.Test/QuickFiler.Test.csproj` declares `AnyCPU` at line 12 and defines `OutputPath` only under the conditions `Debug|AnyCPU` (line 32), `Release|AnyCPU` (line 41), `Debug|x86` (line 49) and `Release|x86` (line 53), so a project-file build invoked with `Any CPU` matches no property group and fails with `The BaseOutputPath/OutputPath property is not set for project 'QuickFiler.Test.csproj'`, which would make this task's own "the msbuild invocation exits 0" condition unsatisfiable. Write `FEATURE/evidence/regression-testing/regression-fail-before.2026-09-05T10-49.md` with `Timestamp:`, `Command:` for both invocations, `EXIT_CODE:` for both, `ExpectedExitCode: 1` for the vstest invocation, and an `Output Summary:` listing every test name with its outcome.

Do not copy the `.trx` into the evidence folder. + +- [x] [P1-T5] Replace the body of `ThrowIfOffUiBoundary` in `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs` so ownership is proved by owner-thread identity through the `Dispatcher` captured in the constructor. The method reads the viewer's `UiDispatcher`, returns without effect when it is null (preserving the inert behavior fact 9 depends on), and otherwise throws `InvalidOperationException` when `CheckAccess()` is false. The message keeps its existing first sentence shape, `"{operation} must be called on the thread that owns this ItemViewer. "`, and its second sentence is rewritten so it no longer claims a synchronization-context comparison; the replacement second sentence states that the calling thread is not the thread the viewer was constructed on. Add `using System.Windows.Threading;` to the file's using block in its correct sorted position, and remove `using System.Threading;`, which becomes unused. Do not remove or alter the `UiSyncContext` property or any other member. Acceptance, all five required: `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs` contains at least one occurrence of the literal `CheckAccess()`; it contains zero occurrences of the literal `ReferenceEquals(SynchronizationContext.Current`; it contains exactly one occurrence of the literal `using System.Windows.Threading;`; a `Select-String -SimpleMatch 'using System.Threading;'` over that one file returns zero matches, which together with a clean P2-T4 build establishes that no unqualified `SynchronizationContext` remains in executable code, since such a reference would not compile without that using; and the file remains at or below 500 lines. The `CheckAccess()` condition is a lower bound rather than an exact count on purpose: the P1-T6 documentation rewrite may legitimately name the member, and an exact-count gate would then fail on correct work. The second and fourth conditions are deliberately narrow so they do not collide with the prose the P1-T6 and P1-T7 comment edits must contain. + +- [x] [P1-T6] Rewrite the XML documentation on `ThrowIfOffUiBoundary` (the `` and `` block that begins at line 406 before this edit) so it describes the thread-identity contract and states why context reference equality was unsuitable. The `` must state that a viewer constructed inside a WPF dispatcher operation captures a `DispatcherSynchronizationContext` that is never again the UI thread's ambient context, and must reference issue #781. Remove the superseded claim that a thread id is not a boundary proof. Acceptance, all three required: the documentation block contains the literal `DispatcherSynchronizationContext`; it contains the literal `#781`; and it contains zero occurrences of the literal `a thread id is not a boundary proof`. + +- [x] [P1-T7] Correct the `EnsureBreadcrumbResourceOwnership` statement-order comment (lines 380 through 388 before this edit) so it stays accurate under the new guard, without changing statement order. The comment must continue to state that the affinity guard is the first statement and that the issue #488 D5 `ObjectDisposedException` throw is the first action, and must replace the two clauses that describe the old mechanism: the clause naming a null `UiSyncContext` becomes a clause naming a null owning dispatcher, and the closing sentence naming a `SynchronizationContext` comparison becomes one naming a thread-identity check. Acceptance, all four required: the comment block contains the literal `first statement`; it contains the literal `first action`; `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs` contains zero occurrences of the literal `SynchronizationContext comparison after a throw`; and it contains zero occurrences of the literal `when UiSyncContext is null`. Both prohibited literals are single-line today (they sit on the current lines 388 and 383 respectively), so each condition is false before this edit and true after it. + +- [x] [P1-T8] Delete the two obsolete D4 tests from `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs`: `InitializeBreadcrumbPipeline_AmbientContextNull_ThrowsBoundaryDiagnostic` and `InitializeBreadcrumbPipeline_DifferentNonNullContext_ThrowsBoundaryDiagnostic`, together with their XML documentation blocks (lines 152 through 244 before this edit). In the same task, correct the one surviving comment in that file that the guard change falsifies: the `` on the private `SetViewerSyncContext` helper ends with the clause `so the D4 affinity guard is inert for that viewer`, which stops being true once the guard keys on `_uiDispatcher` rather than `_context`. Rewrite that clause to say that nulling `_context` reproduces the issue #475 shape and that the affinity guard now keys on the owning dispatcher, so it still admits the call on the owning thread. This is a comment-accuracy correction in the same file and the same concern as the deletion; the file must not encode the superseded reference-comparison contract in tests or in prose. Change nothing else in the file: the D1 test, both D3 tests, the D5 test, the two issue #475 tests, and the bodies of every private helper (`SeamProbeDropDownHost`, `UninitializedEnvironment`, `Host`, `SetViewerSyncContext`, `DrainableSynchronizationContext`, `ViewerScope`) are unchanged, and no test method name changes. Acceptance, all five required: the file contains zero occurrences of the literal `InitializeBreadcrumbPipeline_AmbientContextNull_ThrowsBoundaryDiagnostic`; zero occurrences of the literal `InitializeBreadcrumbPipeline_DifferentNonNullContext_ThrowsBoundaryDiagnostic`; exactly one occurrence each of the literals `InitializeBreadcrumbPipeline_SecondDifferentProvider_ThrowsInvalidOperationException`, `InitializeBreadcrumbPipeline_RepeatSameProvider_DoesNotThrowAndKeepsCoordinator`, and `InitializeBreadcrumbPipeline_AfterViewerDisposed_ThrowsObjectDisposedException`; the file contains zero occurrences of the literal `so the D4 affinity guard is inert for that viewer`, which sits on a single line today (line 409) so the condition is false before this edit and true after it; and the file's line count has decreased by at least 90 from its pre-edit count of 480. The line-count condition is stated as a decrease rather than an exact figure because the deletion leaves two adjacent blank lines that CSharpier may collapse in P2-T1, which would make an exact figure unsatisfiable in one of the two orderings. + +- [x] [P1-T9] Rebuild and re-run both affected test classes. Run `msbuild QuickFiler.Test\QuickFiler.Test.csproj /t:Rebuild /m /p:Configuration=Debug /p:Platform=AnyCPU`, using the same `AnyCPU` project-file platform value and for the same reason stated in P1-T4, then run the resolved `vstest.console.exe` against `QuickFiler.Test\bin\Debug\QuickFiler.Test.dll` with `/InIsolation /Logger:trx "/ResultsDirectory:TestResults\pass-after-781" "/TestCaseFilter:FullyQualifiedName~ItemViewerBreadcrumbThreadAffinityTests|FullyQualifiedName~ItemViewerBreadcrumbLifecycleRegressionTests|FullyQualifiedName~QfcItemControllerBreadcrumbDropDownTests|FullyQualifiedName~ItemViewerBreadcrumbDropDownContractTests" "/Settings:scripts\vscode\TaskMaster.cli.runsettings"`.

Acceptance, all five required: both invocations exit 0; the failed count is 0; all seven `ItemViewerBreadcrumbThreadAffinityTests` methods are recorded as Passed; `InitializeBreadcrumbPipeline_SecondDifferentProvider_ThrowsInvalidOperationException`, `InitializeBreadcrumbPipeline_RepeatSameProvider_DoesNotThrowAndKeepsCoordinator`, and `InitializeBreadcrumbPipeline_AfterViewerDisposed_ThrowsObjectDisposedException` are each recorded as Passed; and `ConfigureBreadcrumbDropDown_SeededLifecycleNullUiContext_DoesNotThrow` is recorded as Passed, which is the sibling issue #475 test that the guard change puts back under an active affinity check for the first time. + +- [x] [P1-T10] Verify the AC7 scope boundary. In one task run `git add --intent-to-add --all -- QuickFiler QuickFiler.Test`, then `git diff --name-status main -- QuickFiler QuickFiler.Test` (substituting the `BASE_REF:` value recorded in P0-T3 for `main` when that task recorded `origin/main`), then `git status --porcelain --untracked-files=all -- QuickFiler QuickFiler.Test`, then `git diff --name-only main..HEAD -- QuickFiler QuickFiler.Test` with the same ref substitution. The two-dot form is required for the second invocation and the three-dot form must not be substituted: `git diff --name-status main...HEAD` compares two commits and never reads the working tree, so because this plan never commits it reports an empty list for these pathspecs however the executor edits those files. The two-dot form compares the base commit against the working tree, which is the comparison the `--intent-to-add` companion completes: without that entry the new test file is untracked and invisible to any diff. The porcelain span remains required because it observes untracked paths directly and would still report them if the intent-to-add step were skipped. The fourth invocation is the commit-to-commit form and is recorded under the literal heading `INHERITED PATHS:`; it exists to establish, by observation rather than by assertion, that no commit already on this branch touches these two pathspecs, so every path the second invocation reports is this plan's own uncommitted work. Write `FEATURE/evidence/qa-gates/scope-boundary.2026-09-05T10-49.md` with `Timestamp:`, `Command:` for all four invocations, `EXIT_CODE:` for all four, and an `Output Summary:` giving the union of the paths reported by the second and third invocations plus the `INHERITED PATHS:` heading. Acceptance, all four required: `INHERITED PATHS:` is present and lists no path; the union contains zero paths beginning `QuickFiler/Controllers/`; the union contains zero paths matching `QfcCollectionController` or `QfcItemController`; and every path in the union is one of `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs`, `QuickFiler.Test/Viewers/ItemViewerBreadcrumbThreadAffinityTests.cs`, `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs`, `QuickFiler.Test/QuickFiler.Test.csproj`. If `INHERITED PATHS:` lists any path, do not proceed on the assumption that the union is this plan's own work: report the listed paths to the orchestrator and subtract them from the union before evaluating the remaining three clauses. + +- [x] [P1-T11] Check off AC1 in `FEATURE/issue.md` by changing the single line beginning `- [ ] AC1: ` to `- [x] AC1: `, preserving the criterion text exactly. Evidence: the P1-T5 acceptance conditions, namely at least one occurrence of `CheckAccess()` and zero occurrences of `ReferenceEquals(SynchronizationContext.Current` in `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs`, together with P1-T9. The lower-bound wording matches P1-T5 exactly; version 1.2 relaxed that condition from an exact count because the P1-T6 documentation rewrite may legitimately name the member a second time, and citing an exact count here would reintroduce the condition that correction removed. Acceptance: `FEATURE/issue.md` contains exactly one line beginning `- [x] AC1: ` and no other AC line changed in this task. + +- [x] [P1-T12] Check off AC2 in `FEATURE/issue.md` by changing the single line beginning `- [ ] AC2: ` to `- [x] AC2: `. Evidence, one named test per ambient shape AC2 enumerates: the null ambient context by `InitializeBreadcrumbPipeline_OwningThreadNullAmbientContext_DoesNotThrow`; a different plain `SynchronizationContext` instance by `InitializeBreadcrumbPipeline_OwningThreadDifferentPlainContext_DoesNotThrow`; and a `DispatcherSynchronizationContext` installed by a WPF dispatcher operation by `ConfigureBreadcrumbDropDown_OwningThreadInsideDispatcherOperation_DoesNotThrow`, with `InitializeBreadcrumbPipeline_ConstructedInsideDispatcherOperation_SucceedsUnderDifferentAmbientContext` covering the converse case of a viewer captured inside a dispatcher operation and called outside one. All four recorded Passed in `FEATURE/evidence/regression-testing/regression-pass-after.2026-09-05T10-49.md`.

Evidence: the P1-T6 and P1-T7 acceptance conditions, together with the P1-T8 condition that the file contains zero occurrences of `so the D4 affinity guard is inert for that viewer`, which covers the sibling comment the guard change would otherwise have left inaccurate. Acceptance: exactly one line beginning `- [x] AC6: ` and no other AC line changed in this task. + +- [x] [P1-T17] Check off AC7 in `FEATURE/issue.md` by changing the single line beginning `- [ ] AC7: ` to `- [x] AC7: `.

Before the run, capture `git status --porcelain --untracked-files=all`; after the run, capture it again. Write `FEATURE/evidence/qa-gates/csharpier-format.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and an `Output Summary:` that quotes the tool's `Formatted` summary line verbatim and records both porcelain captures. The exit code alone cannot distinguish a clean run from a repairing one, which is why both the summary line and the two tree observations are required. Acceptance: the artifact exists, both porcelain captures are recorded, and if the two captures differ, the differing paths are all inside the Write Set. If any path outside the Write Set was rewritten, revert that path and rerun. + +- [x] [P2-T2] Run `dotnet tool run csharpier check .` from the repository root. Write `FEATURE/evidence/qa-gates/csharpier-check.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and an `Output Summary:` quoting the tool's final summary line verbatim. Acceptance: `EXIT_CODE:` is 0.

Write `FEATURE/evidence/qa-gates/msbuild-analyzers.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and an `Output Summary:` giving the warning count and error count. Acceptance: `EXIT_CODE:` is 0, the error count is 0, and the warning count is at or below the count recorded in `FEATURE/evidence/baseline/msbuild-analyzers.2026-09-05T10-49.md`. If the step fails or any file changed, restart the loop from P2-T1. + +- [x] [P2-T4] Run `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true`. Do not add `/p:Nullable=enable` and do not substitute `/t:Build`. Write `FEATURE/evidence/qa-gates/msbuild-nullable.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and an `Output Summary:` giving the warning count and error count. Acceptance: `EXIT_CODE:` is 0 and the error count is 0. If the step fails or any file changed, restart the loop from P2-T1. + +- [x] [P2-T5] Run the scoped in-project test gate. Invoke the `vstest.console.exe` resolved in P0-T4 as `vstest.console.exe QuickFiler.Test\bin\Debug\QuickFiler.Test.dll /EnableCodeCoverage /InIsolation /Logger:trx "/ResultsDirectory:TestResults\final-quickfiler-781" "/TestCaseFilter:TestCategory!=LiveOutlook" "/Settings:scripts\vscode\TaskMaster.cli.runsettings"`. `/InIsolation` is mandatory: without it the assembly binding redirects in the test assembly's `.config` are ignored and the run produces mass empty-message sub-millisecond failures that are an invocation defect, not a regression. Write `FEATURE/evidence/qa-gates/mstest-quickfiler.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and an `Output Summary:` giving total, passed, failed, and skipped counts plus the fully-qualified name of every failed test. Acceptance, both required: every failed test name recorded here is a member of `BASELINE_FAILURE_SET` from P0-T8, so the failure set did not grow; and the exit-code expectation is recorded by the following mechanical rule, which admits no other outcome. When the failed count is 0, `EXIT_CODE:` must be 0 and no `ExpectedExitCode:` line is written. When the failed count is greater than 0 and every failed name is a member of `BASELINE_FAILURE_SET`, write `ExpectedExitCode: 1` and list those names. When any failed name is not a member of `BASELINE_FAILURE_SET`, the task fails; do not write an `ExpectedExitCode:` line. Do not copy the `.trx` into the evidence folder. This run can stall: `/EnableCodeCoverage` over the whole `QuickFiler.Test.dll` has been observed on this workstation to freeze the testhost on one attempt and to complete in about twelve seconds on an identical retry, because `scripts/vscode/TaskMaster.cli.runsettings` requests one worker per logical processor at class level and the pump-host tests are load-sensitive. Do not abort it on a short timeout. If it stalls, sample the testhost process CPU time twice about twenty seconds apart to distinguish a hang from a slow run, terminate only this task's own `vstest.console` and `testhost` chain and no shared MSBuild or compiler worker, then rerun the identical command. A rerun with no intervening file change is not a toolchain-loop restart; record in the artifact that no file in the Write Set changed between the two attempts. + +- [x] [P2-T6] Run the final repository-wide test and coverage pass using the same throwaway script as P0-T8, invoked as `pwsh -NoProfile -File "$env:TEMP\taskmaster-781-coverage.ps1" -CoverageOutput "coverage\final-781.cobertura.xml" -ResultsDirectory "TestResults\final-781"`. Write `FEATURE/evidence/qa-gates/mstest-coverage.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:` (the printed `COLLECT_EXIT_CODE:`), and an `Output Summary:` giving total, passed, failed, and skipped counts and the fully-qualified name of every failed test. Acceptance, all three required: every `ASSEMBLY:` line printed is free of the substring `\.claude\`; `ASSEMBLY_COUNT:` equals the value recorded in P0-T8, so the two runs cover the same assembly set and their coverage denominators are comparable; and every failed test name is a member of `BASELINE_FAILURE_SET`. Record the exit-code expectation by the same mechanical rule stated in P2-T5. This run takes tens of minutes; do not abort it on a short timeout. + +- [x] [P2-T7] Post-process the final Cobertura and answer the changed-code coverage question. Run the P0-T9 block with `.\coverage\final-781.cobertura.xml` substituted for the baseline path, then append the results to `FEATURE/evidence/qa-gates/mstest-coverage.2026-09-05T10-49.md` and write the changed-code determination to `FEATURE/evidence/qa-gates/changed-code-coverage.2026-09-05T10-49.md`. That artifact records `Timestamp:`, `Command:` (the post-processing block and the class-count query), `EXIT_CODE:`, and an `Output Summary:` carrying: the six root Cobertura attribute values; the observed `ItemViewerBreadcrumbClassCount`; and one of exactly two determinations, selected by that count and by nothing else. + - When the count is `0`: record `CHANGED-CODE COVERAGE: NOT MEASURABLE`. State that `QuickFiler/Viewers/ItemViewer.cs` line 20 carries `[ExcludeFromCodeCoverage]` on the `ItemViewer` partial class, that the attribute applies to the whole type including the members declared in `ItemViewer.Breadcrumb.cs`, and that the collector therefore emits no class element for that file, so the changed production lines are outside the coverage denominator and no percentage exists to compare against 90 percent. Record, as the substitute behavioral evidence, that every outcome of both conditionals in the rewritten `ThrowIfOffUiBoundary` is exercised by a named passing test: the null-owner early return by `InitializeBreadcrumbPipeline_NullOwningDispatcher_DoesNotThrow`; the non-null owner with `CheckAccess()` true by `InitializeBreadcrumbPipeline_OwningThreadNullAmbientContext_DoesNotThrow`, `InitializeBreadcrumbPipeline_OwningThreadDifferentPlainContext_DoesNotThrow`, `InitializeBreadcrumbPipeline_ConstructedInsideDispatcherOperation_SucceedsUnderDifferentAmbientContext`, and `ConfigureBreadcrumbDropDown_OwningThreadInsideDispatcherOperation_DoesNotThrow`; and the non-null owner with `CheckAccess()` false by `InitializeBreadcrumbPipeline_WorkerThread_ThrowsBoundaryDiagnostic` and `ConfigureBreadcrumbDropDown_WorkerThread_ThrowsBoundaryDiagnostic`. Do not cite `ConfigureBreadcrumbDropDown_SeededLifecycleNullUiContext_DoesNotThrow` as null-owner evidence: it nulls `_context`, not `_uiDispatcher`, so after this change it exercises the `CheckAccess()`-true path instead. + - When the count is not `0`: record `CHANGED-CODE COVERAGE: MEASURED` together with the per-file covered-line and valid-line counts read from the class elements whose `filename` ends `ItemViewer.Breadcrumb.cs`, and the resulting percentage. Acceptance in this branch: that percentage is at or above 90. + + Acceptance for the task as a whole: the artifact exists, records the observed class count, and carries exactly one of the two determination lines. -**Phase 0 — Context & Inputs** -- [ ] [P0-T1] Link approved spec: -- [ ] [P0-T2] Record branch/commit baseline: -- [ ] [P0-T3] List required environment/fixtures/data: +- [x] [P2-T8] Produce the two final coverage artifacts. First, run the P0-T10 projection block with `.\coverage\final-781.cobertura.xml` as input and `FEATURE/evidence/qa-gates/coverage-final.jacoco.2026-09-05T10-49.xml` as output. Second, copy the post-processed `.\coverage\final-781.cobertura.xml` to `artifacts/csharp/coverage.xml`, creating `artifacts/csharp/` if absent. AC8 names the canonical artifact as Cobertura, so this is a verbatim copy and not a format conversion; the copy is git-ignored and exists for the feature reviewer, who parses the root `line-rate` and `branch-rate` attributes directly. Acceptance, all three required: the JaCoCo file exists and its derived `lines-covered`, `lines-valid`, `branches-covered` and `branches-valid` totals equal the final Cobertura root values exactly; `artifacts/csharp/coverage.xml` exists and its root element is `/#781-.py` only if no clear home exists) -- [ ] [P2-T2] [expect-fail] Run the regression to confirm it fails and captures the repro +- [x] [P2-T10] Audit file sizes after formatting. Record the line counts of `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs`, `QuickFiler.Test/Viewers/ItemViewerBreadcrumbThreadAffinityTests.cs`, and `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs` in `FEATURE/evidence/qa-gates/file-size-audit.2026-09-05T10-49.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, and an `Output Summary:` listing each path and its count. This runs after P2-T1 because CSharpier can change line counts. Acceptance: all three counts are at or below 500. -**Phase 3 — Minimal Fix** -- [ ] [P3-T1] Apply the smallest change needed to make the regression test pass; avoid opportunistic refactors +- [x] [P2-T11] Check off AC8 in `FEATURE/issue.md` by changing the single line beginning `- [ ] AC8: ` to `- [x] AC8: `. Evidence: `EXIT_CODE: 0` in the P2-T2, P2-T3, and P2-T4 artifacts from one consecutive loop pass; the P2-T5 and P2-T6 failure-set acceptance; the changed-code determination in `FEATURE/evidence/qa-gates/changed-code-coverage.2026-09-05T10-49.md`; and the existence of `artifacts/csharp/coverage.xml` proved by P2-T8. Acceptance: exactly one line beginning `- [x] AC8: ` and no other AC line changed in this task. -**Phase 4 — Verification Loop** -- [ ] [P4-T1] Re-run repro and regression test to confirm expected behavior -- [ ] [P4-T2] Run formatter → linter → type checker → tests; restart loop if any step changes files or fails -- [ ] [P4-T3] Record baseline, post-change, and comparison artifact paths for each in-scope language where coverage is required +- [x] [P2-T12] Mirror the issue update to `FEATURE/evidence/issue-updates/issue-781.2026-09-05T10-49.md` with `Timestamp:`, the exact AC checkbox state of `FEATURE/issue.md` after P2-T11, and `PostedAs: body` together with the issue URL, or a `POSTING BLOCKED` header and the reason when the GitHub update cannot be made from this session. Acceptance: the artifact exists and carries one of `PostedAs: body`, `PostedAs: comment`, or a `POSTING BLOCKED` header. -**Phase 5 — Documentation & Status** -- [ ] [P5-T1] Update spec/issue with outcomes, decisions, and any deviations from scope +- [x] [P2-T13] Delete the throwaway session script `$env:TEMP\taskmaster-781-coverage.ps1`, then stage the Write Set without committing it. In one task run `git add -- QuickFiler QuickFiler.Test docs/features/active/2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781`, then run `git status --porcelain --untracked-files=all`. **Do not commit.** The orchestrator commits through the commit-message agent per the orchestrate skill, so plan execution ends with a staged, uncommitted tree; a commit issued here would bypass that agent. Acceptance, all four required: the throwaway session script no longer exists; every path in the Write Set that changed appears in the porcelain output with a staged status code in the first column, that is `M`, `A`, or `R`, rather than an unstaged-only code; the porcelain output lists no staged path under `coverage/`, `TestResults/`, or `artifacts/`, which holds because the `git add` span above is scoped to three pathspecs that exclude all three trees, and not because `.gitignore` covers them: lines 144, 39 and 57 ignore `coverage/*`, `[Tt]est[Rr]esult*/` and `artifacts/` for untracked paths only, and `artifacts/orchestration/orchestrator-state.json` is a tracked file that no ignore rule affects; and `git rev-parse HEAD` returns the same commit recorded by P0-T3, proving no commit was created by this plan. -**Phase 6 — PR & Handoff** -- [ ] [P6-T1] Prepare PR notes (summary, risks, validation performed, links to tests) and request review +- [x] [P2-T14] Write the reduced-audit handoff record to `FEATURE/evidence/other/reduced-audit-handoff.2026-09-05T10-49.md` and hand off to the small-path reviewer. The record names the reduced artifact set the short-path audit consumes, enumerated as explicit paths rather than as counts: `FEATURE/issue.md` with AC1 through AC8 all checked; every file under `FEATURE/evidence/baseline/`; every file under `FEATURE/evidence/regression-testing/`; every file under `FEATURE/evidence/qa-gates/`; `FEATURE/evidence/issue-updates/issue-781.2026-09-05T10-49.md`; `FEATURE/evidence/other/implementation-handoff.2026-09-05T10-49.md`; the pre-existing `FEATURE/evidence/other/dispatcher-synccontext-probe.2026-09-05T10-40.md`; and the git-ignored review input `artifacts/csharp/coverage.xml`. It also names the one item requiring reviewer judgment: the `CHANGED-CODE COVERAGE:` determination recorded by P2-T7, together with the `QuickFiler/Viewers/ItemViewer.cs` line 20 `[ExcludeFromCodeCoverage]` citation that produces it. Then, because P2-T13 staged the Write Set before this artifact existed, re-stage the feature folder: run `git add -- docs/features/active/2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781`, then `git status --porcelain --untracked-files=all -- docs/features/active/2026-09-05-breadcrumb-ui-boundary-guard-rejects-dispatcher-built-viewers-781`. **Do not commit.** Acceptance, all four required: the artifact exists; every path it lists resolves on disk; the `CHANGED-CODE COVERAGE:` determination line is reproduced in it verbatim; and the porcelain output for the feature folder lists no path whose status code is `??`, so no evidence artifact is left untracked. The plan-checkbox writes for P2-T13, P2-T14 and P2-T15 are made after this staging span and are expected to leave `FEATURE/plan.2026-09-05T10-49.md` with the porcelain code `MM`, which is a staged and then further modified tracked file rather than an unstaged path; the orchestrator's commit step covers that residual. -**Phase 7 — Rollout / Follow-up** -- [ ] [P7-T1] Capture deployment/rollout notes and post-fix monitoring items -- [ ] [P7-T2] Record links (issue, PRs, related docs) for traceability +- [x] [P2-T15] Emit the acceptance-criteria status summary in the executor's final report, in the exact form required by `.claude/skills/acceptance-criteria-tracking/SKILL.md`: `Source:` naming `FEATURE/issue.md`, `Total AC items:`, `Checked off (delivered):`, `Remaining (unchecked):`, and `Items remaining:`.

The orchestrator subsequently resolved the asset and + supplied it, and this document was repaired in place against it. All canonical major headings, + the coverage-metrics-by-language table with the template's seven-column header, the Coverage + Evidence Checklist, section 1.2.1, and both appendices are now present, and the template + instruction block is removed. +2. **`validate_orchestration_artifacts` is not on this agent's tool surface.** The orchestrator runs + it. Substitute check performed locally by the reviewer: the `SubagentStop` hook + `.claude/hooks/validate-feature-review-coverage.ps1` was dot-sourced and executed against the + three artifacts this review produced, including a stress run with the real coverage figures + forced in.

Result in the Evidence Location Compliance section. + +## Rejected Scope Narrowing + +No caller instruction narrowed the audit scope, and none was accepted. The delegating prompt +states "Scope determination is yours per your scope invariant." The audit was performed against +the full branch diff of 44 paths. + +Two statements in the supplied inputs were evaluated as candidate narrowings and both were found +**not** to be narrowings of the audit: + +1. `plan.2026-09-05T10-49.md` line 21 records that removing the class-level exemption on the + `ItemViewer` type lies outside this issue's implementation write set. That constrains the fix. + It does not instruct any reviewer to skip a check, and the executor produced complete + repository-wide measurement regardless. The reviewer independently measured the same figures. +2. `evidence/other/reduced-audit-handoff.2026-09-05T10-49.md` enumerates a "reduced artifact set" + for the `minor-audit` short path. That enumeration selects which evidence documents the audit + consumes; it does not restrict which files are diffed. The full 44-path diff was audited, and + two branch paths absent from that enumeration — the nine `.claude/agent-memory/**` files and the + deleted `artifacts/orchestration/orchestrator-state.json` — were audited on their own merits and + produced Finding F5. + +## Evidence Location Compliance + +Scan command: +`git diff --name-only a007f72e..4f74aa39 | grep -E "^artifacts/(baselines|qa|evidence|coverage)/"` + +Result: no matching path. **PASS.** + +All executor evidence is written under the canonical `/evidence//` tree: +`baseline/` (9 files), `regression-testing/` (2), `qa-gates/` (11), `issue-updates/` (1), +`other/` (4). No `EVIDENCE_LOCATION_OVERRIDE_REJECTED` event occurred during this review; the three +artifacts produced here are written to the feature folder root as the agent contract requires. + +Absolute-host-path scan over all 43 added and modified tracked paths in the range +(`C:\Users\` and account-name tokens): **0 hits. PASS.** The one tracked file that did +contain an absolute host path with the OS account name, +`artifacts/orchestration/orchestrator-state.json`, is deleted by this branch (see Finding F5). + +--- + +## 1. General Unit Test Policy Compliance + +### 1.1 Core Principles + +| Requirement | Status | Evidence | +|------------|--------|----------| +| **Independence** - Tests run in any order | PASS | Every new test either owns its `ViewerScope` or constructs its viewer inside the test body; every ambient `SynchronizationContext` substitution is restored in a `finally`. No static mutable state is shared across tests. | +| **Isolation** - Each test targets single behavior | PASS | Each of the seven new tests targets one guarded member under one ambient-context shape. | +| **Fast Execution** - Tests complete quickly | PASS | Re-measured in this session: the four affected classes complete in 2.60 s for 33 tests; the seven new tests total 1.47 s, dominated by the first WinForms `InitializeComponent()` at 950 ms. | +| **Determinism** - Consistent results | PASS | Five independent executions across the executor's runs and this session, all agreeing test by test. No sleeps, timers, wall-clock waits, or temporary files. One theoretical inlining dependency is recorded as code-review finding CR-5 (Low) and was not reproduced. | +| **Readability & Maintainability** - Clear structure | PASS | Every test carries an XML ``; the two non-obvious shapes carry a `` explaining why the repeat-call form is required rather than stylistic. | + +### 1.2 Coverage and Scenarios + +| Requirement | Status | Evidence | +|------------|--------|----------| +| **Baseline Coverage Documented** | PASS | **Baseline (pre-development):** 84.8347% lines, 79.1542% branches, `lines-covered` 54922, `lines-valid` 64740, 9 instrumented assemblies.
**Command:** repository-wide `Invoke-MSTestWithCoverage.ps1` run producing `coverage/baseline-781.cobertura.xml`.
**Timestamp:** 2026-09-05 (task P0-T8/P0-T9).
Re-read directly from the document by the reviewer, not transcribed from the executor's artifact. | +| **No Coverage Regression** | FAIL, non-blocking | **Post-change coverage:** 84.8316% lines, 79.1421% branches.
**Change:** -0.0031% lines, -0.0121% branches.
**Status:** No regression attributable to this branch. Denominators are identical at `lines-valid` 64740 and assembly count 9. A class-by-class diff of the two documents found 3 differing classes out of 564, all in untouched `UtilitiesCS`. Every `QuickFiler` class is identical and the `QuickFiler` package counters are unchanged at LINE missed=2376 covered=9960. The row is recorded FAIL only because the absolute figure 84.8316% sits below the 85% uniform floor; disposition in section 1.2.2. | +| **New Code Coverage >= 90%** | PASS with deviation | **New/modified production files:** `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs`.
**New code coverage:** 100%, measured as 3 of 3 reachable outcomes of the rewritten guard, each covered by a named passing test.
**Calculation method:** the changed lines are outside the instrumented denominator because the enclosing type carries `[ExcludeFromCodeCoverage]`, so no line percentage exists. The reviewer enumerated the guard's reachable outcomes from the source, mapped a named test to each, executed all seven tests, and observed five of them fail against the pre-fix guard and pass against the fixed guard. Detail in section 5.3 and finding F2. | +| **Comprehensive Coverage** | PASS | **Changed member tested:**
- `ThrowIfOffUiBoundary(string)` (lines 428-444): 7 tests across 3 outcomes
- Guard call sites reached: `InitializeBreadcrumbPipeline` (line 51), both `ConfigureBreadcrumbDropDown` overloads (lines 172, 229), `EnsureBreadcrumbResourceOwnership` (line 389, reached through `EnsureBreadcrumbLifecycle` at line 361)
**Untested code:** none added by this branch. | +| **Positive Flows** - Valid inputs | PASS | Three ambient-context shapes on the owning thread, all expected to succeed: `InitializeBreadcrumbPipeline_ConstructedInsideDispatcherOperation_SucceedsUnderDifferentAmbientContext`, `InitializeBreadcrumbPipeline_OwningThreadNullAmbientContext_DoesNotThrow`, `InitializeBreadcrumbPipeline_OwningThreadDifferentPlainContext_DoesNotThrow`, plus `ConfigureBreadcrumbDropDown_OwningThreadInsideDispatcherOperation_DoesNotThrow`.
**Total positive tests:** 4 | +| **Negative Flows** - Invalid inputs | PASS | Cross-thread calls must be rejected: `InitializeBreadcrumbPipeline_WorkerThread_ThrowsBoundaryDiagnostic` and `ConfigureBreadcrumbDropDown_WorkerThread_ThrowsBoundaryDiagnostic`, each asserting `InvalidOperationException` whose message contains the member name.
**Total negative tests:** 2 | +| **Edge Cases** - Boundary conditions | PASS | `InitializeBreadcrumbPipeline_NullOwningDispatcher_DoesNotThrow` nulls the private `_uiDispatcher` field by reflection, while asserting the field still exists so a rename fails loudly, and confirms the guard stays inert.
**Total edge case tests:** 1 | +| **Error Handling** - Error paths | PASS | Both cross-thread tests assert the exception type, that the message names the operation, and explicitly that it is not an `ObjectDisposedException`, which keeps the issue #488 D5 disposal contract distinguishable from the boundary contract.
**Total error handling tests:** 2 | +| **Concurrency** - If applicable | PASS | Applicable and covered at the level the contract permits. The guard is a precondition check, not a synchronization primitive; its own documentation states it declares and enforces the contract without making the read-then-write atomic. Cross-thread rejection is tested with a real second thread. A true two-thread data race is not reproducible deterministically under the repository ban on sleeps and wall-clock waits, and the tests correctly do not claim to prove race absence. | +| **State Transitions** - If applicable | PASS | The relevant transition is uninitialized to initialized pipeline. `InitializeBreadcrumbPipeline_RepeatSameProvider_DoesNotThrowAndKeepsCoordinator` and `InitializeBreadcrumbPipeline_SecondDifferentProvider_ThrowsInvalidOperationException` cover the repeat and conflicting-provider transitions and were re-executed passing by the reviewer. | + +### 1.2.1 Per-Language Coverage Comparison + +- C#: Baseline: 84.8347% lines (54922/64740) -> Post-change: 84.8316% lines (54920/64740). Change: -0.0031% lines (-2 covered lines, identical denominator). New/changed-code coverage: 100%. Disposition: FAIL. Evidence: `coverage/baseline-781.cobertura.xml`, `artifacts/csharp/coverage.xml`, `/evidence/qa-gates/coverage-delta.2026-09-05T10-49.md`, `/evidence/qa-gates/changed-code-coverage.2026-09-05T10-49.md`. +- PowerShell: Baseline: N/A.

Evidence: N/A - zero TypeScript files changed on this branch. + +### 1.2.2 Disposition of the C# Coverage Row + +The FAIL disposition above is **non-blocking**. Three reasons, each verified in this session: + +1. **Pre-existing.** The baseline measurement at merge base `a007f72e` is 84.8347%, already below + 85%. The shortfall predates the branch and is not caused by it. +2. **Governing-floor conflict, both floors reported.** `CLAUDE.md` UT2 sets the repository floor at + `>= 80%`; `.claude/rules/quality-tiers.md` sets it at `>= 85%` uniformly across T1-T4. The two + documents are unreconciled in this repository. The measured 84.8316% clears the first and misses + the second. This audit reports against the stricter of the two and therefore records FAIL, so + that the row is not silently upgraded by choosing the looser document. +3. **No attributable movement.** A class-by-class diff of the two Cobertura documents, performed by + the reviewer, found exactly three differing classes out of 564, all in `UtilitiesCS` and none + touched by this branch: `UtilitiesCS.OlTableExtensions` (0.885522 -> 0.912458, improved), + `UtilitiesCS.HelperClasses.SegmentStopWatch` (1.0 -> 0.944954), and `UtilitiesCS.SubjectMapSco` + (0.969466 -> 0.938931). The -2 movement is run-to-run nondeterminism in unrelated code. + +No `remediation-inputs` artifact is emitted on this row. The correct disposition is procedural +rather than a code defect in this change. + +The new/changed-code figure of 100% is stated in outcomes rather than lines for the reason given +beside the metrics table and expanded in section 5.3 and finding F2. + +### 1.3 Test Structure and Diagnostics + +| Requirement | Status | Evidence | +|------------|--------|----------| +| **Clear Failure Messages** | PASS | Every FluentAssertions call in the new file supplies a `because` string. The non-vacuity assertion states the failure meaning directly: "the dispatcher operation must have captured a context that is not the thread's ambient context, or this test would pass vacuously". | +| **Arrange-Act-Assert Pattern** | PASS | All seven new tests carry literal `// Arrange`, `// Act`, `// Assert` comments in that order, with the act phase captured into an `Action` and asserted through `.Should().Throw<...>()` or `.Should().NotThrow(...)`. | +| **Document Intent** | PASS | Test names encode member, thread, ambient shape, and expectation, for example `InitializeBreadcrumbPipeline_OwningThreadDifferentPlainContext_DoesNotThrow`. The class carries a `` naming issue #781 and a `` explaining why it declares its own scope helpers rather than widening the accessibility of the sibling file's private helpers. | + +### 1.4 External Dependencies and Environment + +| Requirement | Status | Evidence | +|------------|--------|----------| +| **Avoid External Dependencies** | PASS | No Outlook, network, database, remote API, or external process. No filesystem access. The only host facility used is the WPF `Dispatcher` for the current thread, which is in-process. | +| **Use Mocks/Stubs** | PASS | `IFolderHierarchyProvider` is a `MockBehavior.Strict` Moq double, so any unexpected call fails the test. `InertDropDownHost` is a hand-written `IBreadcrumbDropDownHost` fake. `DrainableSynchronizationContext` queues posted work so nothing escapes the test thread. | +| **Environment Stability** | PASS | Grepped the new test file for `GetTempPath`, `GetTempFileName`, and `TempDirectory`: 0 hits, so the prohibition on temporary files is met. Ambient `SynchronizationContext` is the only global touched, and every substitution is restored in a `finally` or in `ViewerScope.Dispose`. | + +### 1.5 Policy Audit Requirement + +| Requirement | Status | Evidence | +|------------|--------|----------| +| **Pre-submission Review** | PASS | This document is the required pre-submission policy review. Outstanding review items are the four non-blocking residuals enumerated in section 10; none gates the PR. | + +--- + +## 2. General Code Change Policy Compliance + +### 2.1 Before Making Changes + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Objective clarified from stated assumptions | PASS | `issue.md` states the root cause with a runtime probe (`evidence/other/dispatcher-synccontext-probe.2026-09-05T10-40.md`) whose decisive line is `Invoke ctx == outer ambient : False`, and explicitly rejects an earlier competing hypothesis with reasons. | +| Existing change plan read | PASS | `plan.2026-09-05T10-49.md` version 1.3 is the approved plan of record; Phase 0 task P0-T1 records the mandated policy reading order and the nine files read. | +| Plan documented before execution | PASS | The plan predates the fix commit and carries a preflight revision record at `evidence/other/preflight-round1-revisions.2026-09-05T19-59.md`. | +| Bugfix workflow, failing regression test first | PASS | Independently reproduced by the reviewer. See section 6. | + +### 2.2 Design Principles + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Simplicity first | PASS | Net production change is 24 added and 17 removed lines; the guard body shrank by one statement while the documentation grew. | +| Reusability | PASS | The single private `ThrowIfOffUiBoundary` remains the one implementation shared by all four guard sites, so the fix applies at every site without duplication. | +| Extensibility | PASS | No public signature changed. `UiSyncContext` is retained for its existing consumers across the `QuickFiler` controllers. | +| Separation of concerns | PASS | The change is confined to a precondition check. No I/O and no control manipulation were added. | + +### 2.3 Module & File Structure + +| Requirement | Status | Evidence | +|------------|--------|----------| +| File size limit, 500 lines | PASS | Re-measured with `awk END{print NR}`: `ItemViewer.Breadcrumb.cs` 456, `ItemViewerBreadcrumbThreadAffinityTests.cs` 419, `ItemViewerBreadcrumbLifecycleRegressionTests.cs` 388. All below 500. | +| Module cohesion | PASS | The new test file holds one test class plus three private test-support types, all serving that class. | +| Small, intentional public surface | PASS | No member was promoted in visibility. The new test file declares its own scope helpers precisely so that the sibling file's `private` helpers are not widened, which the class `` states explicitly. | +| Explicit imports, no circular dependencies | PASS | `System.Windows.Threading` replaces the now-unused `System.Threading` in the changed production file. | +| I/O boundaries | PASS | No new I/O. | +| Dependencies | PASS | No package reference added. `WindowsBase` was already referenced by the `QuickFiler` project, and the constructor already captured `Dispatcher.CurrentDispatcher` before this branch. | + +### 2.4 Naming, Docs, and Comments + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Descriptive naming | PASS | `PascalCase` types and members, `camelCase` locals throughout the diff. The local `owning` names the captured dispatcher by its role. | +| Public API documentation | PASS | `ThrowIfOffUiBoundary` carries a rewritten `` and ``. | +| Comment why, not what | PASS | The rewritten `` explains the dispatcher-context reason the previous comparison was unsuitable. One accuracy note is recorded as code-review finding CR-4 (Low), which does not change this verdict. | +| Dependent comments kept accurate | PASS | The `EnsureBreadcrumbResourceOwnership` statement-order comment was updated in the same commit: it now reasons about the owning dispatcher being null rather than about `UiSyncContext` being null, so the FIRST STATEMENT and FIRST ACTION argument it documents remains true after the swap. | + +### 2.5 After Making Changes - Toolchain Execution + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Full toolchain run in order | PASS | Format, then lint and analyzers, then type and nullable check, then tests. Section 7 records each command and exit code. | +| One consecutive passing pass | PASS | No stage modified a file and no stage failed, so no restart from step 1 was required. | +| Reviewer re-execution | PASS | The reviewer independently re-ran the format stage over the two changed directories and the test stage over the four affected classes. Both passed. | + +### 2.6 Summarize and Document + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Key changes summarized | PASS | `evidence/other/implementation-handoff.2026-09-05T10-49.md` and section 9 of this document. | +| Supporting documents updated | PASS | `issue.md` acceptance criteria checked off; `plan.2026-09-05T10-49.md` task checkboxes updated; `evidence/issue-updates/issue-781.2026-09-05T10-49.md` mirrors the issue update. | +| Next steps provided | PASS | `evidence/other/reduced-audit-handoff.2026-09-05T10-49.md` enumerates the review inputs and names the single reviewer-judgment item, which this audit resolves in finding F2. | + +--- + +## 3.

Reviewer re-ran `dotnet tool run csharpier check ./QuickFiler/Viewers ./QuickFiler.Test/Viewers`: `Checked 89 files in 614ms`, exit 0. | +| `dotnet format` not used | PASS | Absent from every recorded command. No project file was rewritten; the only `.csproj` change is one added `` line. | +| Analyzers with `/t:Rebuild` | PASS | `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true`, exit 0, 3 warnings and 0 errors, equal to baseline. The gate is non-vacuous: the log records 36 `csc.exe` command lines. The three warnings are all `MSB3061` `CoreClean` file-deletion diagnostics caused by a running Outlook process holding output binaries; they are present identically at baseline and no analyzer rule identifier appears. | +| Nullable and type check, correct command shape | PASS | `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true`, exit 0, 3 warnings and 0 errors, equal to baseline. `/p:Nullable=enable` correctly omitted and `/t:Build` correctly not substituted, so the gate could have failed. | + +#### 3C#.2 C# Design & Type-Safety + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Strong contracts and explicit APIs | PASS | The guard's contract is now stated as owner-thread identity in the XML documentation and enforced by one expression. The local is explicitly typed `Dispatcher owning`, not `var`. | +| Null-safety | PASS | The null-owner early return is retained and re-keyed onto the dispatcher. No new nullable-flow warning was introduced, confirmed by the `TreatWarningsAsErrors` build. | +| Composition and focused types | PASS | No type was added to production code. | +| Asynchrony and resource safety | PASS | No async or disposable surface changed. | + +#### 3C#.3 C# Error Handling and Suppressions + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Fail fast with explicit exceptions | PASS | `InvalidOperationException` is thrown with a message naming the operation; no broad catch was added. | +| No new suppressions | PASS | No `#pragma warning disable` and no new `[ExcludeFromCodeCoverage]` appears anywhere in the diff. The pre-existing class-level attribute on `ItemViewer` was neither added nor altered by this branch. | + +--- + +## 4. Language-Specific Unit Test Policy Compliance + +Applicable language: C#.

No MSTest `Assert.` call appears in the added code. | + +#### 4C#.2 Test Style and Structure + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Sealed test class, no shared fixture state | PASS | `public sealed class ItemViewerBreadcrumbThreadAffinityTests` with no `[ClassInitialize]` or static field. | +| Deterministic disposal | PASS | `ViewerScope` implements `IDisposable` and is used in `using` blocks; the one test that constructs its viewer outside a scope disposes it in a `finally`. | + +#### 4C#.3 Naming and Readability + +| Requirement | Status | Evidence | +|------------|--------|----------| +| Behavioural test names | PASS | Names follow member, condition, expectation.

The reviewer independently enumerated every `` element in both documents and found zero whose `filename` ends `ItemViewer.Breadcrumb.cs`, and likewise zero for `ItemViewer.cs`. The cause is `[ExcludeFromCodeCoverage]` on the `ItemViewer` partial class declaration at `QuickFiler/Viewers/ItemViewer.cs` line 20, which applies to the whole type including the members declared in this file. The attribute predates the branch, since the same enumeration returns zero on the baseline document, and it is the maintainer-ratified CLAUDE.md UT2(b) WinForms form-derived exemption.

Gaps and Exceptions + +### Identified Gaps + +#### F1 — `coverage-delta` misattributes the coverage movement — **PARTIAL, non-blocking** + +`evidence/qa-gates/coverage-delta.2026-09-05T10-49.md` states the two-line movement "is consistent +with the deletion of the two obsolete D4 tests in +`QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs`: those tests drove the +old reference-comparison throw path". That explanation is not supported by the documents it cites, +and it is self-contradictory: the same artifact establishes that the old reference-comparison throw +path lives in a type outside the denominator, so exercising it or not cannot move any counter. + +Reviewer measurement: the `QuickFiler` package counters are identical in both documents +(LINE missed=2376 covered=9960); all three differing classes are in `UtilitiesCS` and none is +touched by this branch. The movement is run-to-run nondeterminism in unrelated code. + +A second, smaller citation defect appears in the same artifact: it states that test projects are +excluded from instrumentation "by `coverage.config`". The committed `coverage.config` contains only +seven third-party `ModulePath` excludes and no test-assembly entry; the `.*\.Test\.dll$` exclusion +is injected at run time by `Invoke-MSTestWithCoverage.ps1` line 99. The substantive effect the +artifact relies on is real, but the citation names the wrong mechanism. + +Impact: the artifact's conclusion, that no regression is attributable to this change, is correct +and is in fact strengthened by the corrected measurement, so this changes no verdict. The defect is +in the recorded rationale. The orchestrator has appended a "Correction recorded by the +orchestrator" section to that artifact carrying this finding. Not blocking. + +#### F4 — PR context summary misclassifies the changed C# files — **PARTIAL, tooling defect, non-blocking** + +`artifacts/pr_context.summary.txt` is fresh, since its Head SHA `4f74aa39...` equals current `HEAD`, +but its "Changed files overview" reports "Core logic changes: 0 files" and places all changes under +"Docs/templates/agents/tooling: 30 files", listing only ten Markdown paths. The branch actually +changes 44 paths including three `.cs` files and one `.csproj`. + +Consequence for enforcement: `.claude/hooks/validate-feature-review-coverage.ps1` derives its +changed-language set from that summary's `- (+N/-N)` bullets, so it computes an empty +language set and skips its per-language checks entirely. This audit therefore does **not** rely on +the summary for scope. Scope was recomputed with +`git diff --numstat a007f72e394ee3038c6c52bfdf91f007df96fd6c..4f74aa39799dca7233bcf286dac90e8691eabd99`, +and the verdicts in sections 1.2.1 and 5.2 are written as if the hook were enforcing them. + +This is a recurring defect in the context-collection tooling, not a defect in this branch. It is +recorded here so the branch is not credited with a check that was never actually exercised. + +#### F5 — Unrelated tracked-file deletion bundled into the fix commit — **Minor, non-blocking** + +Commit `4f74aa39` deletes `artifacts/orchestration/orchestrator-state.json`, 386 lines, alongside +the guard fix. The file is stale checkpoint state from an unrelated feature, since its `objective` +names PR #704 CI format recovery and its `workspace_root` names a different worktree; it sits under +a path matched by `.gitignore` line 57; and it contained an absolute host path including the OS +account name. Removing it from tracking is beneficial, and the local working copy is intact on disk +at 24,709 bytes with mtime 2026-09-05 17:20, so no orchestration state was lost. + +The objection is traceability only: the deletion is unmentioned in the commit subject +`fix(781): use dispatcher CheckAccess for breadcrumb UI-boundary guard` and lies outside the AC7 +write set. Recommendation: mention it in the PR body. Not blocking. + +#### F6 — Latent defect recorded only as feature-folder prose — **Minor, action recommended before merge** + +`issue.md` records, under "Related observations, not in scope for the fix", that +`UtilitiesCS/Threading/UiThread.cs` line 100, `SynchronizationContextAwaiter.IsCompleted`, uses the +same reference comparison, so `await viewer.UiSyncContext` always posts rather than continuing +inline for a dispatcher-built viewer. The reviewer confirmed the code at that location is unchanged +by this branch and the described behaviour is accurate. This is an extra dispatch hop, not a +failure. + +Feature-folder prose does not survive merge. Recommendation: promote this observation to a GitHub +issue through the promotion lifecycle before the feature folder is archived. The same applies to +the `BreadcrumbUiDispatcher.IsCurrentBoundary` divergence recorded as code-review finding CR-7. + +**Status: discharged.** The orchestrator promoted the observation to issue #784, recorded at +`docs/features/potential/promoted/2026-09-05-uithread-synccontext-awaiter-always-posts-for-dispatcher-built-viewers.md`. +The finding stands as recorded; only its recommended action is now complete. + +### Approved Exceptions + +#### F2 — AC8's 90% new-code clause is unevaluable as a line percentage — **PASS with recorded deviation** + +No line percentage exists for the changed production lines, because `ItemViewer` carries +`[ExcludeFromCodeCoverage]`. The clause is therefore answered by substitute behavioural evidence, +reported as 100% of reachable guard outcomes in the metrics table and in section 1.2.1. + +The reviewer judges the substitute sufficient, on these grounds: + +1. The rewritten method has exactly two conditionals and three reachable outcomes: null owner + returns; non-null owner with `CheckAccess()` true returns; non-null owner with `CheckAccess()` + false throws. A named, passing test exists for each — seven tests across the three outcomes. +2. Five of those tests were independently observed to fail against the pre-fix guard and pass + against the fixed guard in this session, so they discriminate on the changed behaviour rather + than merely execute it. +3. The exemption is pre-existing, applies to the whole type, and is the maintainer-ratified + CLAUDE.md UT2(b) WinForms form-derived exemption. Removing it would be a materially larger + refactor of a WinForms `UserControl` and is properly a separate work item. + +Deviation recorded so a maintainer can overrule: if the maintainer requires a measured line +percentage rather than branch-complete behavioural evidence, the only remedy is to extract the +guard logic out of the `UserControl`-derived type into a host-neutral class. That is a separate +issue and not a defect in this change. + +#### F3 — Repository-wide C# line coverage below the 85% uniform floor — **FAIL, non-blocking** + +Recorded and disposed in section 1.2.2, with the figures in section 5.2. Pre-existing at the merge +base, not attributable to this branch, and clears the 80% floor stated in `CLAUDE.md`. The +80-versus-85 conflict between `CLAUDE.md` UT2 and `.claude/rules/quality-tiers.md` remains +unreconciled at the repository level and is outside this branch's remit. + +### Removed/Skipped Tests + +Two tests were removed, both deliberately and both correctly: + +- `InitializeBreadcrumbPipeline_AmbientContextNull_ThrowsBoundaryDiagnostic` +- `InitializeBreadcrumbPipeline_DifferentNonNullContext_ThrowsBoundaryDiagnostic` + +Both asserted the defective behaviour directly, so retaining them would require them to fail. Their +replacements invert the expectation for the same two ambient shapes and add the dispatcher-operation +shape that neither original covered, so net coverage of the guard's contract increased. No test was +skipped, marked `[Ignore]`, or otherwise disabled by this branch. + +### UNVERIFIED items + +1. **Manual Outlook verification of the production launch path.** `issue.md` lists manual + verification, launching QuickFiler in standard and high-confidence mode, among the validation + ideas; it is unchecked and no evidence artifact records it. This review cannot execute it, + because it requires a live Outlook session with a mailbox producing folder suggestions. The + reason is environmental and is not a gap in the executor's work. The unit-level evidence + reconstructs the production construction shape, a viewer built inside a `Dispatcher.Invoke` + callback with the pipeline initialized afterwards under a different ambient context, which is + the exact shape the stack trace in `issue.md` shows failing. +2. **CI green run against the branch head.** GitHub CLI is unavailable in this environment and the + PR context reports "CI status (HEAD): (not available)". The repository-wide local suite is green + at 6997 of 6997. The modified-workflow green-run rule is not triggered by this branch, so no + Blocking finding follows from this. + +--- + +## 9.

For any context captured inside a WPF dispatcher operation (which is how every pooled `ItemViewer` is constructed, see issue #781), the captured instance is never the UI thread's ambient context again, so `await viewer.UiSyncContext` always reports not-completed and always posts, even when the caller is already on the UI thread.

Construct an `ItemViewer` through `ItemViewerQueue.Dequeue` (production path: `ViewerQueueCore.CreateWithPriority` inside `UiThread.Dispatcher.Invoke`), so `viewer.UiSyncContext` is a `DispatcherSynchronizationContext`. +2. On the UI thread, outside any dispatcher operation (ambient context is the persistent `WindowsFormsSynchronizationContext`), evaluate `viewer.UiSyncContext.GetAwaiter().IsCompleted`. +3. Observe `false`; `await viewer.UiSyncContext` therefore posts the continuation instead of continuing inline. + +## Expected Behavior + +An `await` on the UI thread's own synchronization context should continue inline when the caller already runs on the owning thread, regardless of which `SynchronizationContext` instance happens to be ambient at the call site. + +## Actual Behavior + +`IsCompleted` returns `false` whenever the ambient instance differs from the captured instance, so the continuation is always posted through `SynchronizationContext.Post`.

Recorded as out of scope by issue #781 and requested as a promoted follow-up by the #781 feature review (`code-review.2026-09-05T17-29.md`). + +## Suspected Cause / Notes + +Same root mechanism as issue #781: WPF installs a `DispatcherSynchronizationContext` for the duration of each dispatcher operation, so a context captured inside one is a different object from the thread's ambient context afterwards. Reference equality is therefore not a reliable "already on this context" test for dispatcher-captured contexts. + +Related low-severity follow-ups from the #781 review that can ride along with this fix (same file family, same reviewer): + +- `QuickFiler/Viewers/ItemViewer.Breadcrumb.cs`, XML documentation on `ThrowIfOffUiBoundary` (added by #781): the remarks justify the guard with "managed thread ids are unique among live threads", but `Dispatcher.CheckAccess()` compares `Thread` object references, not ids. The guard is stronger than its stated rationale; reword so a future refactor does not weaken it to an id comparison (review finding CR-4). +- `QuickFiler.Test/Viewers/ItemViewerBreadcrumbLifecycleRegressionTests.cs`: the private helper `DrainableSynchronizationContext.Drain()` is never called after the #781 test deletions and can be removed. + +## Proposed Fix / Validation Ideas + +- [ ] Change `IsCompleted` to a thread-identity test where the context exposes one: for a `DispatcherSynchronizationContext`, resolve its `Dispatcher` and use `CheckAccess()`; for `WindowsFormsSynchronizationContext`, compare the owning thread (or fall back to the existing reference comparison only for plain `SynchronizationContext` instances). Alternatively, have `ItemViewer` and `UiThread` capture the persistent WinForms context rather than the transient dispatcher context. +- [ ] Unit coverage: a test that captures a context inside `Dispatcher.CurrentDispatcher.Invoke(...)`, then evaluates `GetAwaiter().IsCompleted` on the same thread under the WinForms ambient context and expects `true`; a `Task.Run` case that expects `false`. +- [ ] Integration scenario to retest: QuickFiler launch in standard and high-confidence mode, confirming no behavior change and fewer posted continuations. +- [ ] Manual verification notes: none beyond the above. + +## Next Step + +- [ ] Promote to GitHub issue (bug-report template) +- [ ] Move to active fix folder / branch
