fix(webview): show modes skeleton until view state loads (vps2 F7) - #1567
Draft PR — vps2 unit F7 (modes skeleton until view state loads).
Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1566 (this series' gap record; the original upstream bug is #915). Port source: upstream PR #928 (fix(webview): add loading skeleton for view state initialization) — closed/superseded; the fork issue 41 ledger names it as the F7 port source (webview-ui sections only).
webview-ui/src/context/ExtensionStateContext.tsx — the viewStateLoaded plumbing: interface field + setViewStateLoaded, the useState (initial false), setViewStateLoaded(true) right after setDidHydrateState(true) in the state-message handler, and both on the context value.
webview-ui/src/components/modes/ModesView.tsx — the loading skeleton (data-testid modes-view-loading-skeleton, aria-busy) returned while viewStateLoaded is false, before the main return, so the modes surface never flashes stale mode/profile text during view-state initialization.
webview-ui/src/components/modes/tests/ModesView.spec.tsx — the mock fields + the "shows a loading skeleton while view-local state is initializing" test (skeleton testid present, mode-select-trigger absent, stale mode/profile text absent).
webview-ui/src/context/tests/ExtensionStateContext.spec.tsx — the TestComponent wiring + 3 tests: initializes false; true after the first state message; setViewStateLoaded callable.
webview-ui/src/App.tsx — the bare webviewDidLaunch useEffect deleted; the payload-carrying webviewDidLaunch post already lives in ExtensionStateContext.tsx (F1c) and is untouched. This hunk was planned for F1c but shipped without it; it is functionally part of the upstream bug fix.
webview-ui/src/tests/App.spec.tsx — the getViewStateId mock field in the vscode mock factory.
src-side coverage carried from the stack lineage (this unit's earlier rounds): the focusInput instance-lookup guard + its two registerCommands.spec tests, the delete-profile prune tests in ClineProvider.spec, the sticky-profile suite, and the profile-deletion comment fix in ClineProvider.ts.
Upstream main 496bd11 merged (this round): 8 conflicts reconciled with both-sides review. App.tsx keeps main's new webviewDidFocus interaction listener while webviewDidLaunch stays removed (ExtensionStateContext posts it once the view state is hydrated; re-posting in App would double the launch message). The refreshed F5/F6 lineage content (fresh-tab createClineTabPanel surface, view-identity fixes, api-spec factory args, tracker constructor args) is carried in; the three new ClineProvider constructions in the delete-profile tests pass the shared tracker.
Budget
Unit delta vs the stack base: 6 webview-ui files, +96/-5 (plus the src-side coverage carried from earlier rounds of this unit). The PR diff vs upstream/main is larger because the branch is stacked on the unmerged F1-F6 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.
How to test
pnpm --dir webview-ui test src/components/modes/__tests__/ModesView.spec.tsx — the skeleton test.
pnpm --dir webview-ui test src/context/__tests__/ExtensionStateContext.spec.tsx — the viewStateLoaded lifecycle tests.
pnpm --dir webview-ui test src/__tests__/App.spec.tsx — launch/focus message wiring.
pnpm --dir src test src/activate/__tests__/registerCommands.spec.ts — the focusInput tab-priority guard tests.
eslint --max-warnings=0 clean on all touched files; eslint-suppressions unchanged (ClineProvider.spec.ts stays at 194; no count increased).
tsc: only 2 local-only errors remain (donor @roo-code/telemetry dist predates the 4-arg captureConsecutiveMistakeError signature; CI builds from source).
Negative control: disabling the skeleton gate reddens ModesView "shows a loading skeleton while view-local state is initializing"; restored byte-exact (sha256 match).
Prettier: full-repo check passes on the PR merge tree (re-verified at the current head).
The apps/vscode-e2e suites (incl. the view-state suite touched by this series) run in CI; they need the real extension host and are not runnable in this local environment.
App.tsx: kept main's webviewDidFocus interaction listener; webviewDidLaunch stays removed (single launch post from ExtensionStateContext).
Carried in the refreshed F5/F6 lineage: fresh-tab createClineTabPanel surface reconciled with main's typed options + shared WebviewFocusTracker, the view-identity review fixes with this series' setValue mode validation / corrupt-entry pruning / mutation-marker load-merge semantics, the restored viewStateReadiness/isDisposed members, api-spec ClineProviderFactory args, and the tracker constructor args across the specs.
The three new ClineProvider constructions in this unit's delete-profile tests now pass the shared tracker.
eslint-suppressions unchanged.
(Second commit 7f5ed4e) Ported the F6 adaptation of main's api-start-new-task.spec.ts to this unit's fresh-tab design (mocks the registerCommands createClineTabPanel function, asserts the exact tracker-carrying payload, pins the factory out of the tab path).
(Third commit 94e7742) Committed the WebviewFocusTracker argument for this unit's three delete-profile test constructions (CI check-types caught that the fix had not been staged into the merge commit).
(Fourth commit 109f821) Prettier-formatted those constructions (CI format:check).
Series mechanics
PR base is main; the branch is stacked on the F6 head; merge order F1a -> F1b -> F1c -> F2 -> F3 -> F4 -> F5 -> F6 -> F7.
CS not-ported register (for consistency): kimi-code OAuth try/catch + routerModels.spec +29; ApiConfigManager min-w-0->grow; ApiConfigManager.visual.tsx deletion + 2 PNG baselines; mojibake comment; providers/, .coderabbit.yaml, .github/, CONTRIBUTING.md, .gitignore churn — none of these touch the files in this PR.
AT-HEAD thread 4251997133 (Trivial, maintainability): the three temporary-id tests now dispose their providers in finally (constructor registers into the static activeInstances), restore the rejecting globalState.update stub in finally, and await the constructor's loadViewState promise instead of a fixed 10 ms sleep; the CloudService double gained on/off for dispose. Proofs: sticky-mode 30/30, eslint clean, prettier gate ALL-MATCHED; test-only change, no mutation control applies.
AT-HEAD thread 4251997137 (Minor, functional correctness) argued: the modes skeleton is unreachable by design because webviewDidLaunch awaits setViewStateId -> loadViewState before the first state post, so viewStateLoaded flipping with didHydrateState is accurate and no wrong-mode frame exists; pre-gating the skeleton would flash it on every boot regardless of the active tab. Details in the thread reply.
CI re-trigger: head fa68982 is an empty commit over 7537805 (no content change) to re-run the flaky e2e-mock lane (known 30s-timeout flake); all verification numbers above apply unchanged.
Security Boundaries / view-state id rows: addressed at 3fd9e42. setViewStateId now rejects non-string ids (crafted postMessage), bounds the key length (MAX_VIEW_STATE_ID_LENGTH), and refuses ids already owned by another live instance; a refused view stays on its temporary id against shared state. Regression tests: non-string, oversized, claimed-by-another-view. Negative controls: disabling the ownership check reddens exactly the claim test; widening the length bound reddens exactly the oversized test; restores byte-exact (hash match).
All three refusal paths resolve viewStateReadiness, so API-driven task creation never falls through to its timeout when a registration is refused.
The spec gained an afterEach clearing the static instance registry (suites construct providers directly and never dispose most of them; leaked instances would claim ids ahead of later tests).
Persistence Integrity setValues/setValue ordering rows: verified already addressed by the pushed code: _saveViewLocalStateFromMutation persists the non-secret subset before updating the buffer; the re-key is a single queued write (no delete-then-write window; authorship clears only after the write lands); the mutation hook keeps the buffer synced across setValue/setValues and profile upsert/activation/deletion.
Vertex credential exposure via loadViewState: addressed by design - persisted viewStates entries carry only mode + currentApiConfigName (non-secret subset); loadViewState resolves the profile into the in-memory buffer, which reaches the webview through the existing ExtensionState apiConfiguration channel, and logs name the profile only. No secret is written to workspace storage.
Proofs at 3fd9e42: sticky-mode 33/33; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Non-activating saves (upsertProviderProfile with activate=false, and the zoo-gateway callback's non-active path) rewrote the profile on disk but left pinned views serving the pre-save snapshot; the non-activating branch now refreshes pinned sibling views (and this view when it holds the pin), and the callback routes through upsertProviderProfile so the refresh cannot be forgotten.
getState() no longer spreads the pinned overlay over the shared provider settings (a key the profile never defined leaked in from the shared profile: model id, region, tuning). The overlay is a complete snapshot: used in place, with only apiProvider falling back to shared state.
Regression tests: "refreshes views pinned to a profile saved without activation"; "does not leak shared provider keys into a pinned view's api configuration; the zoo-gateway callback test asserts the upsert path.
Negative controls: dropping the else-branch refresh reddens exactly the refresh test, reverting the merge semantics reddens exactly the leak test; restores byte-exact (hash match).
Proofs at 5bcc785: ClineProvider.spec green, sticky-mode and webviewMessageHandler green, eslint --max-warnings=0 clean, tsc clean except the two known local telemetry-dist noise lines, prettier merge-ref gate ALL-MATCHED.
Follow-up: overlay read from the view buffer (required-lane fix)
The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw apiConfiguration state key. That key is a partial patch written by shared-store paths, not a view snapshot: with no overlay present and the raw key partial, getState() served only the partial object and dropped the shared provider settings the previous merge produced (the parallel-mode activation tests caught exactly this - the activated profile's model id vanished; required lane red on the units carrying that spec). The overlay is now read from the view buffer itself, where a present value is by contract a complete profile and an absent one means the shared store serves the settings.
Proofs: ClineProvider.parallelMode.spec green where present (the six synchronization tests that regressed), ClineProvider.spec green including the overlay-completeness tests, sticky-mode and webviewMessageHandler green; negative control: reverting the overlay to a shallow merge over the shared settings still reddens exactly the leak test; restores byte-exact (hash match); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Follow-up: active task handlers rebuilt on non-activating saves (head 268bb11)
A review round on the view-identity unit found that the non-activating-save refresh updated pinned views' buffers but not their active tasks' API handlers, and the posted state prefers the task's own apiConfiguration: a conversation running in a view pinned to the saved profile kept sending the old token (e.g. after the Zoo Gateway callback rotated it) even though the view's buffer had caught up. The refresh now rebuilds the affected tasks' handlers in the pinned views, and the non-activating branch rebuilds this view's own handler when it holds the pin.
Proofs: ClineProvider.spec green (the pinned-sibling refresh test now asserts the active task's handler is rebuilt with the saved settings, not just the private buffer); negative control: dropping the rebuild from the refresh reddens exactly that assertion, restores byte-exact (hash match); parallelMode/sticky-mode/webviewMessageHandler green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Follow-up: test-quality round from the review (head 726e230)
The review round on the api-wiring unit named four test-quality issues; the ones present in this unit are fixed here: the viewStates describe block moved out of the alwaysDenyUnapprovedCommands block (test names carried the wrong subject), the prune test's toBeDefined() survival checks replaced with exact-shape toEqual assertions (they pass even if pruning strips fields), the stale-temporary-entry test's fixed 10 ms wait replaced with awaiting the load itself (the negative assertion could pass vacuously on a slow load), and the readiness-cancel test's fake timers restored in a finally block (a failed assertion left fake timers active and hung a later real-timer test).
Proofs: global-settings 9/9 where present, ClineProvider.spec green, sticky-mode green where present, api-task-control green where present; negative controls: pruning that strips updatedAt reddens exactly the prune test, a loadViewState that adopts the unowned temporary-id entry reddens exactly the stale-entry test, restores byte-exact (hash match); eslint --max-warnings=0 clean (src and types); prettier merge-ref gate ALL-MATCHED.
Follow-up: review-round fixes from the series (head f528dcc)
A review round on the mode-profile-writes and e2e-view-state units found fixes this unit carries. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
A review round on the mode-profile-writes unit found that the profile-deletion re-pin updated each sibling view's buffer but not its running task: the posted state prefers the task's own apiConfiguration, so a conversation in a view pinned to the deleted profile kept sending the deleted profile's settings. The re-pin now rebuilds the sibling's API handler with the replacement's settings and re-points the task's sticky profile name, mirroring the activation path.
Proofs: ClineProvider.spec and sticky-mode green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED. The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.
In addition: The view-state readiness bound no longer rejects headless callers whose webview never launched (it only rejects when the webview has launched and readiness failed), and the IPC start-task listener catches rejections since the IPC server does not await async listeners (new headless-fallback and launched-stuck tests; negative control: an unconditional timeout reddens exactly the fallback test). The readiness-cancel test now pins the bound's own timer via fake timers and a zero timer count instead of a global clearTimeout spy, and the mode-ordering test asserts the switch has not been called before the pending initialization is released (negative controls: dropping the timer clear / the initialization await reddens exactly the respective assertion).
Proofs: ClineProvider.spec 299/299, sticky-mode 34/34, parallel-mode 40/40, Task.spec 190/190, api-task-control 26/26; every negative control reddens exactly its target test and restores byte-exact (hash match); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Updated this round (CodeRabbit follow-up, head 78c21d1)
Non-activating profile saves no longer force-rebuild the API handler of a view whose active task follows a different sticky profile: both rebuild sites (the acting view's pinned branch and the pinned-sibling refresh) are guarded by taskApiConfigName === saved profile. Pinned-view overlays still refresh; regression tests cover both sites (negative control: removing either guard reddens exactly its test).
Sticky-mode afterEach now disposes the per-test provider before resetting the instance registry, so providers leave McpServerManager's static provider set between tests.
Test hygiene (head bb3a988, same series-wide round): prune assertions compare full kept entries; the two re-key storage tests seed through the durable write path so their assertions can fail; the webview state-payload test renamed to describe what it asserts.
Updated this round (CodeRabbit follow-up 2, head 41bbc27)
Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite now require taskApiConfigName === deleted profile (the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.
Per the AGENTS.md policy (never add Stryker directives; remove them when a file is touched), all // Stryker disable directives were dropped from this PR. Equivalence rationale for the removed suppressions:
Stryker disable next-line ConditionalExpression: defensive clobber guard, unreachable per the ordering argument above.
Stryker disable next-line StringLiteral: setPanel branches only on type === "sidebar", so any other literal routes to the identical tab-ref assignment
Stryker disable next-line StringLiteral: setPanel only distinguishes "sidebar"; any other value routes to the tab-ref assignment
Stryker disable next-line ConditionalExpression: at the catch, this call's own state-change handler only ever re-points the tracked ref at newPanel itself, so tabPanel === newPanel is the only reachable state here; a concurrent re-pointing race is not representable in this spec.
Stryker disable next-line ConditionalExpression: only tool_use and mcp_tool_use entries ever carry an id — the text block pushed in the text case has no id field and the start events reaching this guard always carry the string id locked in by processRawChunk — so the type check cannot change the outcome of entry.id === event.id for any entry this pipeline produces; the false replacement is additionally killed by the rejection tests.
Stryker disable next-line ConditionalExpression: event.name is always a string on this path — the only delta events reaching this handler are emitted by processRawChunk with the tracked start name (never undefined), so the legacy nameless branch below is unreachable defensive code and the conditional always takes the named side.
Stryker disable next-line ConditionalExpression: streamingKey can never be undefined here — makeStreamingKey always returns a string and the legacy lookup branch above is unreachable (see the directive on the event.name check) — so the null side is unreachable defensive code.
Stryker disable next-line ConditionalExpression, EqualityOperator: streamingKey is always a defined string on this path (makeStreamingKey never returns undefined; the legacy branch is unreachable per the directives above), and processStreamingChunk returns a partial ToolUse for a known key, so both defensive conditions reduce to the partialToolUse check and cannot change the observed behavior.
Stryker disable next-line LogicalOperator: event.name is always a string on this path — finalizeRawChunks emits end events with the tracked start name (a string, set before the tracker can start), so the ?? event.id fallback guards a nameless end event this pipeline cannot produce.
Stryker disable next-line ConditionalExpression, LogicalOperator, EqualityOperator: the both-miss case is unreachable via the raw-chunk pipeline — end events carry the locked start name so the compound key resolves the registered entry, and a same-ID rejected-start end is always processed after the accepted start's end has already removed that entry; this defensive path protects against a cross-name end event the pipeline cannot produce.
Stryker disable next-line ConditionalExpression: unreachable defensive region — getStreamingToolCallById can only resolve when the both-miss case above is reachable, which the raw-chunk pipeline cannot produce (see the directive there).
Stryker disable next-line CallExpression,ObjectLiteral: _updateViewLocalStateFromMutation applies only mode, currentApiConfigName, apiConfiguration and provider-settings keys, so a listApiConfigMeta-only payload (deleted call or empty object) is a behavior-preserving no-op.
Stryker disable next-line ConditionalExpression: in this fallback the view does not pin the deleted profile, so when the deleted profile was not the shared selection profileToActivate equals the shared selection itself; forcing the branch only rewrites that same value back into the store.
Stryker disable next-line ConditionalExpression,BlockStatement: hostile non-stabilizing encodings are unreachable from the webview (its posts are plain link targets); the bound is defensive
Stryker disable next-line CallExpression: hostile non-stabilizing encodings are pinned by the direct decodeUntrustedPathToStable bound test; the webview never posts such values
Stryker disable next-line ConditionalExpression,OptionalChaining: equivalent mutant - when localStorage is unavailable the guard-false path and the throwing body both return this.fallbackState from this catch
Stryker disable next-line ConditionalExpression,OptionalChaining: equivalent mutant - when localStorage is unavailable the guard-false path and the throwing body both mark the write failed and return newState
CR round 2026-10-15 (b)
Ported the payload-customModes fix for setValues mode validation (identical flagged block; regression test added) so the units stay byte-identical at merge.
CR round 2026-10-15 (c)
Ported: shared apiProvider fallback in getConfiguration and the dispose() finally-path deregistration (identical flagged blocks; regression tests added).
Ported: whole-operation deregistration finally in dispose() and createTask mode restore on custom-mode registration failure (identical flagged blocks; regression tests added).
CR round 2026-10-15 (f)
The createTask registration-failure rollback now restores the shared mode and the view's own mode pin independently (unset pin stays unset); divergent-pin regression test added. Same fix in all six units carrying the flagged block.
Activation rollback completeness: the pre-activation snapshot captures the exact durable viewStates map and the rollback restores it through the serialized queue, recovering sibling entries the activation's pruning evicted (CR Persistence Integrity).
setGlobalState persists parsed.data instead of the raw payload (CR Security Boundaries).
Activation writes from the stored record (read-back feeds every post-save consumer; CR Security Boundaries).
Clear/re-point cache divergence is guarded at the ContextProxy#updateGlobalState layer on this unit; the new tests pin that guard.
Verification: new tests are focused negative controls (reverting each guard reddens exactly the matching test); ClineProvider.spec, webviewMessageHandler.spec spot-checks, api specs, spec-inclusive tsc --noEmit, eslint --max-warnings=0 (suppression counts unchanged) and prettier all green on this head.
Merged the current upstream/main (merge commit; the row-9 fix commit is unchanged and is the first parent) to clear the review gate's mergeability hold. Upstream refactored upsertProviderProfile into a new persistProviderProfile method and added a runToCompletion queue option; this unit's transactional body was ported into the new method unchanged and upstream's Promise.allSettled activation fix was adopted in it. ClineProvider.spec, webviewMessageHandler.spec, tsc --noEmit, eslint (suppression counts unchanged) and prettier re-verified green at this head. The first refreshed head's windows unit-test lane caught that upstream's new updateProfileModel tests in ClineProvider.apiHandlerRebuild.spec.ts mock the settings manager with a static getProfile, which starves the post-save read-back; the mock now repoints getProfile at what saveConfig wrote (the real manager's behavior), and the file's 38 tests pass locally alongside the rest of the verification set.
Sidebar and editor-tab views retain their own mode and provider-profile selections across reloads.
Open tasks, settings, marketplace, and history from an editor tab.
Start tasks in a new tab while keeping existing editor tabs open.
Modes show a loading state while view settings are restored.
Bug Fixes
Mode changes apply to the intended task, and messages are still delivered if a mode switch fails.
Improved recovery from provider settings load, save, and profile-change errors.
Per-view selections are excluded from settings imports and exports.
Editor-tab actions target the correct tab without disrupting sidebar actions.
Additional provider credentials are migrated to secure storage and excluded from configuration exports.
The pull request adds persisted per-view modes and provider profiles, task-scoped mode changes, and separate command routing for sidebar and tab panels. It also updates configuration handling, adds test-only API controls, and adds end-to-end checks for view isolation.

Summary
View-state identity and hydration packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, webview-ui/src/utils/vscode.ts, webview-ui/src/context/ExtensionStateContext.tsx, webview-ui/src/components/modes/*, webview-ui/src/App.tsx
Settings and webview messages support persisted view state. The webview creates or reuses a view ID, sends it at launch, and tracks hydration. The modes view displays a loading skeleton until state loads.
Provider state and profile synchronization src/core/webview/ClineProvider.ts, src/core/webview/__tests__/*, src/core/config/ProviderSettingsManager.ts
ClineProvider persists and merges view-local selections. Profile updates, deletion, and resets update affected views. Tests cover persistence, mode switching, and multi-instance behavior.
Durable writes and import/export src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/*
Failed global-state and secret writes restore durable cached values when no newer write supersedes them. Import and export omit viewStates. Imports await reset broadcasts before posting state.
Configuration and profile launch handling src/core/webview/webviewMessageHandler.ts, src/extension/api.ts, src/extension/__tests__/*, src/core/webview/__tests__/webviewMessageHandler.spec.ts
Launch handling registers the view ID and checks profile selections. Configuration reads flatten local settings and filter credential-bearing fields. Writes use provider-level methods. Profile renames repoint pinned views before deleting the old profile.
Task initialization preserves mode writes made during state loading. User submissions and tool calls pass the target task to handleModeSwitch.
Test API and new-task creation packages/types/src/api.ts, src/extension/api.ts, src/extension/__tests__/api-task-control.spec.ts, src/extension/__tests__/api-start-new-task.spec.ts
The API adds test-only task controls and validated global-state access. startNewTask adds preserveOpenTabs and waits for view-state readiness when creating a tab.

Tab title actions use tab-specific commands and target the provider for the tracked panel. Tab creation shares overlapping opens, reuses a live panel, and selects a replacement after disposal. API creates tabs directly instead of using ClineProviderFactory.

Merge Risk: Low · up to 619ff
These narrow failure and concurrency cases remain. The PR is mergeable with owner awareness, though fixing them before merge would avoid stale profile state and missed tab commands.
Security Architecture Review
Security architecture risk:🟡 Moderate · up to 98592
Overlapping configuration updates followed by a storage failure can restore older credentials or safety settings over a newer successful update. Several isolation and recovery controls reduce the risk, but the rollback sequence does not preserve newer changes. No unauthorized credential disclosure was established.
Retained concerns
Medium · security · inferred: Compensating rollback is not conditional on mutation ownership. After a shared configuration write succeeds but its durable view-pin write fails, setValues restores every captured prior value. If another update has meanwhile succeeded, this compensation can overwrite its credentials or safety settings. The pin-write queue and direct-write tokens do not make the combined transition atomic or prevent this stale compensation.
Security review details
Security Blast Radius
inferred — The rollback issue reaches shared configuration, not only one view's durable entry. Its supported exposure is other views and tasks consuming the same extension configuration, including credential-backed API requests and shared approval-policy values. Cross-user, cross-tenant, or infrastructure-level exposure was not established.
Security Findings and Attack Paths
inferred — The supported failure path requires overlapping authorized configuration updates and a failed durable pin write. An older operation then restores its captured settings as a fresh write, potentially replacing a newer successful credential or policy update. This is an integrity and failure-containment concern; no unauthenticated trigger, credential disclosure, or demonstrated tool-execution bypass was established.
Trust Boundaries and Controls
observed — The extension normalizes supplied view identities and rejects the prototype key, but does not bind an accepted identity to its originating panel. This is not evidence of a new credential authorization bypass: both inspected base and head permit webviews to list and activate shared profiles directly. Whether hostile content can obtain another view's identity remains unresolved.
Resilience and Maintainability Implications
observed — Direct settings and secret writes use per-key tokens to prevent an older failed write from rolling back a newer cached value. Inspected provider tests cover isolated compensation failures; they do not establish ownership-safe compensation across overlapping configuration operations.
Hardening Proposals
proposed — Give the combined shared-write and pin-write transition mutation ownership, using version-checked compensation or appropriately scoped serialization. Recovery should restore only values still owned by the failing operation and preserve newer credential and safety-setting updates.

It matches the ModesView loading-state change, the viewStateLoaded plumbing in ExtensionStateContext, and the new ModesView test. The title also uses the conventional fix(webview) prefix. The trailing "(vps2 F7)" tag is a series label, not a description, but it does not make the title misleading.
Full details: Security Boundaries
Explanation
No concrete changed path meets the security failure condition. API.getConfiguration() removes viewStates and filters secret, sensitive, and legacy credential-shaped keys. The test-only global-state API is production-gated, allowlisted, rejects taskHistory and credential keys, and schema-validates writes. Webview view-state IDs are type-checked, normalized, length-limited, and checked against live ownership. Persisted view-state entries contain only mode, profile name, and timestamp fields. Profile activation reads normalized stored records before propagating them.
Full details: Persistence Integrity
Explanation
The prior persistence defect remains in the changed code. clearPersistedViewState adds clearedViewStateIds before awaiting contextProxy.setValue and never removes the tombstone when that write rejects (src/core/webview/ClineProvider.ts:793-803). During activation rollback, _restoreProfileActivationState skips a pruned snapshot entry when that tombstone exists (:2767-2776). A concrete failure sequence is: an activation pin write prunes the oldest sibling from a 50-entry map; the sibling clear rejects after adding its tombstone; a later activation write fails; rollback then omits the sibling even though its clear never committed. The existing tests cover successful clearing and standalone cache restoration, but not this failed-clear plus rollback sequence.
Resolution
Make view-state tombstones operation-aware. Record the prior tombstone state or a per-entry mutation version, and restore that state when the corresponding durable deletion/write fails. Restore a pruned snapshot entry only when no newer committed mutation changed or deleted that entry. Add a failure-injection test with 50 entries where activation prunes a sibling, the sibling clear rejects, a later activation write fails, and the original sibling entry remains present.
Full details: Description check
Explanation
The description has substantial technical content. It covers what the unit changes, how to test it, and verification numbers. It also names the linked issue. However, it does not follow the template well. The "Related GitHub Issue" section does not use the required "Closes: #<number>" form. It cites a fork issue 41 and an upstream issue, and it does not state an approved issue. The Pre-Submission Checklist is not ticked. The Visual Snapshots section does not mention a committed *.visual.tsx snapshot, although the title describes a UI loading state. The description is also long and mixes in stacked-series history, review-round notes, and Stryker notes that do not describe this PR's changes. Its text is also not written in the requested Simplified Technical English style, with many long sentences and contractions-free but dense clauses.
Resolution
In "Related GitHub Issue", replace the fork and upstream references with the approved issue in the form "Closes: #<number>". Confirm that the issue is approved. 2) Tick or explain each Pre-Submission Checklist item. In particular, state whether a *.visual.tsx snapshot was added for the skeleton, since the checklist requires one for UI changes that a user would notice. If none was added, say why. 3) Trim the description to this PR's scope. Move stacked-series, round-by-round, and Stryker notes out of the PR body, or link them elsewhere. 4) Rewrite the description in short, active sentences, as the template asks (Simplified Technical English). 5) Confirm the Documentation Updates section and the Get in Touch section are filled in.
Full details: Regression Evidence
Explanation
The visible loading skeleton change lacks the required visual regression evidence. ModesView.tsx adds a user-visible viewStateLoaded === false skeleton with padding, spacing, animation, rounded blocks, and the bg-vscode-input-background theme token. The added ModesView.spec.tsx only checks DOM state in Vitest. The authoritative PR diff contains no *.visual.tsx test, gallery story, or screenshot baseline, while webview-ui/AGENTS.md:46-57 requires a Playwright snapshot for this type of UI change.
Resolution
Add a deterministic Playwright visual test for the unloaded modes state, register a stable modes-skeleton story in webview-ui/playwright/gallery/stories.tsx, and commit the generated baseline under the visual test's __screenshots__ directory.
Full details: Lifecycle Resource Cleanup
Explanation
The prior lifecycle leak remains in the changed createClineTabPanel path. After resolveWebviewView succeeds, delay(100) and vscode.commands.executeCommand("workbench.action.lockEditorGroup") run outside the only cleanup try/catch (src/activate/registerCommands.ts:493-511). If the lock command rejects, the function rejects while the provider remains in ClineProvider.activeInstances, the panel remains in liveTabPanels and as tabPanel, and the registered panel listeners remain. API.startNewTask({ newTab: true }) directly awaits this function (src/extension/api.ts:258-270), so the failure is reachable. Tests cover initialization failure but no lock-command failure path.
Resolution
Wrap resolveWebviewView, the delay, and the lock command in one cleanup guard. On any failure, remove the panel from liveTabPanels, clear tabPanel only when it still references that panel, dispose the provider, and dispose the panel or its registered listeners. Add a regression test that rejects workbench.action.lockEditorGroup after successful initialization and verifies provider disposal, an empty live-panel registry, and no tracked panel.

2373-2379: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
The stale globalSettings spread reverts the view-pin re-point performed at Line 2356.
globalSettings is captured at Line 2325, before any mutation. It is the full contextProxy.getValues() result, and viewStates is a globalSettingsSchema key, so it is included (ContextProxy.getAllGlobalState maps every GLOBAL_STATE_KEYS entry).
Sequence on this path:
Line 2356: repointPersistedViewStates writes a new viewStates map that points the affected pins at profileToActivate.
Line 2375: setValues({ ...globalSettings, ... }) writes back the viewStates snapshot taken at Line 2325. ContextProxy.setValues iterates every own key, so the pre-re-point map overwrites the corrected one.
The re-point is silently undone. The affected view then rehydrates a deleted profile name after a reload — the exact failure repointPersistedViewStates was added to prevent.
Trigger: this view pins an unrelated profile (so viewPinsDeletedProfile is false and the early return at Line 2368 is skipped) while another view pins the profile being deleted.
No test covers this. The re-point test in src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts Lines 840-866 leaves viewLocalState empty, so it takes the activation branch and returns before Line 2375.
Write only the two keys this path owns instead of replaying a whole stale snapshot.
🐛 Proposed fix
const entries = this.getProviderProfileEntries().filter(({ name }) => name !== profileToDelete.name)
- await this.contextProxy.setValues({- ...globalSettings,- currentApiConfigName: profileToActivate,- listApiConfigMeta: entries,- })+ // Write only the keys this path owns. Replaying the `globalSettings`+ // snapshot taken before `repointPersistedViewStates` would overwrite the+ // re-pointed `viewStates` map with its pre-re-point value.+ await Promise.all([+ this.contextProxy.setValue("currentApiConfigName", profileToActivate),+ this.contextProxy.setValue("listApiConfigMeta", entries),+ ])
Add a regression case that seeds a viewStates pin on the deleted profile, sets viewLocalState.currentApiConfigName to an unrelated profile, and asserts the re-point survives.

In `@src/activate/registerCommands.ts`:
- Around line 238-242: Update the focusInput posting logic near focusPanel to
target whichever surface focusPanel selects: post to the tab provider when
tabPanel is tracked, otherwise post to the sidebar provider when sidebarPanel is
available. Ensure the zoo-code.focusInput action is delivered for both
tracked-surface cases.
In `@src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts`:
- Line 1227: The test “should report a successful switch when the provider
reference is already released” exercises SwitchModeTool.handle with a released
provider reference, not ClineProvider.handleModeSwitch. Move it into the
SwitchModeTool describe/spec section, or rename the enclosing describe block so
it accurately covers both subjects.
- Line 1110: Strengthen the assertion in the lock-enabled branch test around
postMessage by verifying the expected state payload, rather than only checking
that postMessage was called. Update the existing postMessage assertion in
ClineProvider parallel-mode tests while preserving the branch’s intended payload
and message structure.
In `@src/core/webview/__tests__/ClineProvider.sticky-profile.spec.ts`:
- Line 1019: The deleteProviderProfile tests do not cover the unrelated-pin
fallback branch. Add a case in the deleteProviderProfile suite that sets
viewLocalState.currentApiConfigName to a surviving unrelated profile, seeds
viewStates with a pin for the profile being deleted, and verifies after deletion
that the pin points to the replacement profile.
In `@src/core/webview/__tests__/webviewMessageHandler.spec.ts`:
- Around line 124-131: Add an updateSettings test assertion that directly
verifies mockClineProvider.setValue receives the changed setting key and value,
rather than relying on the forwarding mock through contextProxy.setValue. Keep
the existing updateSettings behavior and assertions unchanged while covering the
provider-level write path in webviewMessageHandler.
In `@src/core/webview/ClineProvider.ts`:
- Around line 2345-2348: Replace the message-substring check in the
error-handling branch around ProviderSettingsManager.deleteConfig with a typed
or coded not-found signal exposed by ProviderSettingsManager. Swallow only that
explicit not-found condition as idempotent success, while propagating all other
deletion failures, including errors whose profile names contain “not found.”
- Around line 3648-3656: Update setValues in src/core/webview/ClineProvider.ts
at lines 3648-3656 to reject any present, non-undefined mode unless it is a
string matching a known slug, while preserving omission of undefined values.
Update the mode: 42 test in src/core/webview/__tests__/ClineProvider.spec.ts at
lines 1601-1603 to assert the invalid value is dropped from global and
view-local state and the previous mode remains.
- Around line 1823-1825: Update the postMessage rejection handler in
ClineProvider to accept the error and route it through this.log instead of
silently swallowing it. Preserve the fire-and-forget behavior and existing
handling of expected webview disposal rejections.
- Around line 799-815: Update the merge logic around mode, currentApiConfigName,
and apiConfiguration to detect changes by own-property presence rather than
requiring a defined post-load value, so an explicit clear removes a previously
persisted field while an untouched field remains stable. Preserve existing merge
behavior for newly provided values, and add a regression test covering a
persisted mode cleared while the profile lookup is in flight.
In `@src/core/webview/webviewMessageHandler.ts`:
- Line 659: Remove the name check from the re-pin condition in the webview
message handler so a valid global selection is reused whenever globalStillValid
and globalConfigName are present. Add coverage for an invalid view pin with a
valid global selection and an undefined first-entry name, asserting
saveViewState uses the global name and updateGlobalState is not called.
- Line 893: Update the updateSettings handling around provider.setValue so keys
in PROVIDER_SETTINGS_KEYS are routed through the shared provider-settings path
without mutating viewLocalState.apiConfiguration. Preserve local-state updates
for non-provider settings and ensure getState can continue reflecting shared
provider changes across views.
In `@src/extension/__tests__/api-task-control.spec.ts`:
- Line 296: Update the describe block containing the task-ask registry identity
and selectTaskFollowupSuggestion error-handling tests so its name reflects those
test subjects rather than the review process; preferably move each test into the
existing task ask registry and selectTaskFollowupSuggestion describe blocks.
In `@src/extension/api.ts`:
- Line 55: Change listenersRegisteredFor from Set<ClineProvider> to
WeakSet<ClineProvider>, preserving the existing duplicate-registration guard and
all registration checks.

- Around line 290-307: Move the commandPalette contribution containing
zoo-code.plusButtonClickedInTab, zoo-code.settingsButtonClickedInTab,
zoo-code.marketplaceButtonClickedInTab, and zoo-code.historyButtonClickedInTab
from the contributes root into contributes.menus, preserving each command and
its activeWebviewPanelId condition.

…onal-configuration path
Pre-merge checks at head:
- Persistence Integrity (error): when a mode write fails, compensation awaited each restore but only logged a failed one, so a caller could be told "configuration failed" while a restore had also failed and left partial durable state. The mode, profile and shared-setting restores now collect every failure; when any restore fails the call rejects with an error that names each failed compensation step and carries the original write failure as its cause (plus a restoreFailures list).
- Regression Evidence (warning): added the focused optional-configuration test — startNewTask({ text }) creates a task, passes undefined to the provider and performs no configuration write.
api-set-configuration 8 passed, api-start-new-task 7 passed, tsc clean.
Review thread (Lifecycle Resource Cleanup): startNewTask created a provider for a new tab, registered listeners, and then awaited readiness, eviction, webview posts and createTask; if any of those failed, the aborted provider stayed in the active-instance list.
The call now tracks whether it created the provider and wraps the whole post-creation path: on any failure before a task is created it disposes only that provider (which also untracks it) and logs a dispose failure instead of masking the original error; the sidebar provider and its task are never touched.
Tests: new-tab task-creation failure and pre-task post failure each assert the created provider is disposed once and the sidebar provider is not. api-start-new-task 9 passed; tsc clean.
…ation path
Review threads at head:
- The readiness barrier is now a plain await: the guard only enters when a view exists or a new tab is being created, so a timeout is a real failure and task creation rejects instead of falling back to shared state. The headless test no longer advances the 3000 ms timer, so a regression back into the timeout fallback fails it.
- Every configuration-write path now collects compensation failures: the shared-write path, the profile-save path and the mode-write path all funnel through restoreConfigurationValues(previous, restoreFailures) and failWithCompensation(error, restoreFailures), which throws the original error as the cause with the failed restore steps named and a restoreFailures list attached.
Tests: the task-control headless test asserts completion without timer advancement; two new specs reject the restore setValues on the shared-write and profile-save paths and assert restoreFailures. api-task-control + api-set-configuration + api-start-new-task 45 passed; tsc clean.
…ile deletion
The rollback snapshot stripped both name and id before saveConfig, so the restored record lost its manager identity (the next getProfile/saveConfig round trip sees a different record). Strip only the name key; the original id is part of the record identity. This matches the fix in the owner unit (Zoo-Code-Org#1550, 6390402). ClineProvider suite 324 passed.
The refresh merge no longer contains the single no-explicit-any occurrence in core/config/ContextProxy.ts; eslint rejects stale suppression entries. Removed that entry only (verified with --prune-suppressions locally; no other counts changed).
Merging the refreshed F5 head into F6 brought F5 parallelMode assertions (the active task of a view pinned to a deleted profile must have its handler rebuilt and sticky name re-pointed) while the conflicted ClineProvider was taken from the F6 side, whose rePinViewLocalStateForDeletedProfile only re-pointed the view buffer. Port F5 helper body: when the sibling task runs under the deleted profile, rebuild via updateTaskApiHandlerIfNeeded and persistStickyProviderProfileToCurrentTask. ClineProvider.parallelMode.spec.ts 40 passed; ClineProvider suites pass.
The windows platform-unit run failed only on EnvironmentTeardownError (closing rpc while onUserConsoleLog was pending) in ModelSelector.spec.tsx; the same webview suite passes locally and on other platforms. No source change.
…n surface
The refresh merge brought the F6 api-configuration tests (configuration must not expose or write back per-view viewStates) but the conflicted api.ts was taken from the F7 side, which predates that strip. getConfiguration drops viewStates from the flat surface and setConfiguration strips a caller snapshot before setValues/saveConfig, matching the F6 unit. api-configuration + api-set-configuration specs 13 passed; tsc clean.
…fails
Review follow-up: setValues snapshots the sidebar view local mode/currentApiConfigName overrides (including whether each key was present) before applying a mutation. On failure it restores the shared ContextProxy values and then restores each prior local override through saveViewState, clearing keys that had no override and logging a failed overlay restore without masking the original error. The per-view persistence rollback test now gives the view its own overrides and asserts they survive the failed write. ClineProvider.spec.ts 317 passed; tsc clean.
…pins on rollback
Review follow-ups: ContextProxy tracks a state generation and a secret generation (global-state completions compare the state counter, secret completions the secret counter; resetAllState advances both, refreshSecrets only the secret one) so a secrets refresh cannot invalidate an in-flight global-state completion. deleteProviderProfile snapshots this view local pin and its own durable viewStates entry before activation; on failure it restores the local buffer via _updateViewLocalStateFromMutation (including absence) and restores its own durable entry to the pre-activation value while merging sibling updates from the fresh map. ContextProxy + ClineProvider + parallelMode + sticky-profile specs 441 passed; tsc clean.
Re-point the tracked tab before disposing a failed tab panel.
When resolveWebviewView rejects, the catch block clears tabPanel at lines 502-503. The disposal handler at lines 474-486 only selects a surviving tab when tabPanel === newPanel, so the failed panel's disposal cannot select one. Until the surviving tab becomes active again, plusButtonClickedInTab, settingsButtonClickedInTab, historyButtonClickedInTab, and marketplaceButtonClickedInTab return without action. The next "Open in editor" call also creates a new tab. Use the same selection as the disposal handler before disposing the failed provider:

Learning: In webview-ui/src/context/ExtensionStateContext.tsx and webview-ui/src/components/modes/ModesView.tsx, viewStateLoaded is an intentional component-level loading guard, not a requirement to display a modes skeleton during startup. webview-ui/src/App.tsx starts on the chat tab and returns null until didHydrateState is true. In src/core/webview/webviewMessageHandler.ts, webviewDidLaunch awaits ClineProvider.setViewStateId before its initial state post; successful registration in src/core/webview/ClineProvider.ts awaits rekeyPersistedViewStateEntry and loadViewState. Do not recommend moving modes-specific loading UI above the App hydration gate solely because the skeleton is unreachable during normal startup.

Move the storeSecret tests out of the updateGlobalState describe block.
These tests call storeSecret and assert getSecret:
Lines 299-310
Lines 312-343
Lines 345-352
Lines 354-376
Lines 378-429
Lines 455-479
They are still inside describe("updateGlobalState"), which spans Lines 217-593. If you filter a run by storeSecret, these regression cases do not run. The earlier thread says the Line 455 case moved in #1557. At this head, it has not moved. Move all of these tests into the existing describe("storeSecret") block at Line 606.
As per path instructions: "Check that describe block names match the actual subjects of the tests they contain."

600-606: 🩺 Stability & Availability
Readiness is already settled on registration failure.
setViewStateId resolves viewStateReadiness in its finally block. This also runs when rekeyPersistedViewStateEntry or loadViewState rejects, so the reported timeout path does not occur.
… rollback
Review follow-up: deleteProviderProfile snapshots whether this view had an apiConfiguration overlay (and its value) before activation, and restores it together with currentApiConfigName via _updateViewLocalStateFromMutation when a later step fails, so the view cannot stay pinned to the replacement configuration after a failed deletion. ClineProvider + parallelMode + sticky-profile specs 382 passed; tsc clean.
…n the F7 unit
Review follow-ups: deleteProviderProfile snapshots the manager-owned selection and restores it with the existing _restoreProviderManagerSelection helper after a failed deletion (the F6 overlay/pin restore came in via the merge). The e2e view-state test only approves completed asks and follow-up suggestions (partial !== true) and restores the original persisted viewStates in a finally block. The handleModeSwitch queue test releases the gate, restores the spy, cleans fake timers, and disposes in a finally block. The API constructor no longer stores the unused providerFactory: the parameter and every call site were updated, and the fresh tab keeps using the direct createClineTabPanel call. ClineProvider + parallelMode + sticky-profile specs 395 passed; API/extension specs 48 passed; tsc clean.
Five review threads addressed (beaa44e1a, with the F6 overlay/pin restore merged from 987388b75)
e2e completion/follow-up handlers — view-state.test.ts now approves a completion_result ask and consumes a follow-up suggestion only when message.partial !== true; the existing type/ask checks stay for completed messages.
Reload-test state restoration — the test captures the original persisted viewStates before writing the rehydration marker and restores it with globalThis.api.setGlobalState in a finally block, so a failed assertion or reload cannot leak the marker into later suites.
handleModeSwitch queue test cleanup — gate release, switchSpy restoration, fake-timer cleanup, and provider.dispose() now run in finally; the gate is released before the spy is restored so queued mutations can settle even on failure.
Deleted-profile rollback pins — deleteProviderProfile now also snapshots this view's apiConfiguration overlay (and the manager-owned selection) before activation; the rollback restores the overlay together with currentApiConfigName via _updateViewLocalStateFromMutation and restores the manager selection with _restoreProviderManagerSelection. The overlay/pin half is also merged down from the F6 unit (987388b75).
Unused providerFactory — the API constructor no longer accepts/stores it; extension.ts and every test call site were updated, the obsolete factory-injection test was removed, and startNewTask keeps the direct createClineTabPanel(...) call for a fresh tab.
Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.
Follow-up to the providerFactory removal: delete the unused makeClineProviderFactory/makeUnusedTabFactory imports and local helper definitions, and the unused ClineProviderFactory type import in api.ts. tsc clean; eslint --prune-suppressions --max-warnings=0 on the touched files exits 0.
Follow-up to the API constructor cleanup: with no production consumer left, delete ClineProviderFactory.ts, its spec, and the makeClineProviderFactory test helper (plus its spec) so knip:production no longer reports an unused file. Restore eslint-suppressions.json to its pre-cleanup content so the PR does not carry unrelated suppression churn. tsc clean; pnpm knip:production exits 0 locally.

Skip deletion rollback after a concurrent reset.
deleteProviderProfile captures previousViewStates before its asynchronous deletion. If resetState clears persisted state during that operation, the queued rollback can write the pre-reset pins back to viewStates. The write queue orders these writes but does not invalidate the stale snapshot.
Capture a reset generation with the deletion snapshot. Increment it before resetState clears state, and skip the rollback when the generation changes. This is a localized ClineProvider correction for the narrow concurrent-reset case.

Draft PR — vps2 unit F7 (modes skeleton until view state loads).
Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1566 (this series' gap record; the original upstream bug is #915). Port source: upstream PR #928 (fix(webview): add loading skeleton for view state initialization) — closed/superseded; the fork issue 41 ledger names it as the F7 port source (webview-ui sections only).
What this unit does at head 109f821
Budget
Unit delta vs the stack base: 6 webview-ui files, +96/-5 (plus the src-side coverage carried from earlier rounds of this unit). The PR diff vs upstream/main is larger because the branch is stacked on the unmerged F1-F6 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.

Proofs: sticky-mode 30/30, eslint clean, prettier gate ALL-MATCHED; test-only change, no mutation control applies.webviewDidLaunchawaitssetViewStateId->loadViewStatebefore the first state post, soviewStateLoadedflipping withdidHydrateStateis accurate and no wrong-mode frame exists; pre-gating the skeleton would flash it on every boot regardless of the active tab. Details in the thread reply.CI re-trigger: head fa68982 is an empty commit over 7537805 (no content change) to re-run the flaky e2e-mock lane (known 30s-timeout flake); all verification numbers above apply unchanged.
Pre-merge ERROR-row pre-check (head 3fd9e42)
setViewStateIdnow rejects non-string ids (crafted postMessage), bounds the key length (MAX_VIEW_STATE_ID_LENGTH), and refuses ids already owned by another live instance; a refused view stays on its temporary id against shared state. Regression tests: non-string, oversized, claimed-by-another-view. Negative controls: disabling the ownership check reddens exactly the claim test; widening the length bound reddens exactly the oversized test; restores byte-exact (hash match).viewStateReadiness, so API-driven task creation never falls through to its timeout when a registration is refused._saveViewLocalStateFromMutationpersists the non-secret subset before updating the buffer; the re-key is a single queued write (no delete-then-write window; authorship clears only after the write lands); the mutation hook keeps the buffer synced across setValue/setValues and profile upsert/activation/deletion.loadViewStateresolves the profile into the in-memory buffer, which reaches the webview through the existing ExtensionState apiConfiguration channel, and logs name the profile only. No secret is written to workspace storage.--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.upsertProviderProfilewithactivate=false, and the zoo-gateway callback's non-active path) rewrote the profile on disk but left pinned views serving the pre-save snapshot; the non-activating branch now refreshes pinned sibling views (and this view when it holds the pin), and the callback routes throughupsertProviderProfileso the refresh cannot be forgotten.getState()no longer spreads the pinned overlay over the shared provider settings (a key the profile never defined leaked in from the shared profile: model id, region, tuning). The overlay is a complete snapshot: used in place, with onlyapiProviderfalling back to shared state.--max-warnings=0clean, tsc clean except the two known local telemetry-dist noise lines, prettier merge-ref gate ALL-MATCHED.Follow-up: overlay read from the view buffer (required-lane fix)
The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw
apiConfigurationstate key. That key is a partial patch written by shared-store paths, not a view snapshot: with no overlay present and the raw key partial,getState()served only the partial object and dropped the shared provider settings the previous merge produced (the parallel-mode activation tests caught exactly this - the activated profile's model id vanished; required lane red on the units carrying that spec). The overlay is now read from the view buffer itself, where a present value is by contract a complete profile and an absent one means the shared store serves the settings.Proofs: ClineProvider.parallelMode.spec green where present (the six synchronization tests that regressed), ClineProvider.spec green including the overlay-completeness tests, sticky-mode and webviewMessageHandler green; negative control: reverting the overlay to a shallow merge over the shared settings still reddens exactly the leak test; restores byte-exact (hash match); eslint
--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.Follow-up: active task handlers rebuilt on non-activating saves (head 268bb11)
A review round on the view-identity unit found that the non-activating-save refresh updated pinned views' buffers but not their active tasks' API handlers, and the posted state prefers the task's own
apiConfiguration: a conversation running in a view pinned to the saved profile kept sending the old token (e.g. after the Zoo Gateway callback rotated it) even though the view's buffer had caught up. The refresh now rebuilds the affected tasks' handlers in the pinned views, and the non-activating branch rebuilds this view's own handler when it holds the pin.Proofs: ClineProvider.spec green (the pinned-sibling refresh test now asserts the active task's handler is rebuilt with the saved settings, not just the private buffer); negative control: dropping the rebuild from the refresh reddens exactly that assertion, restores byte-exact (hash match); parallelMode/sticky-mode/webviewMessageHandler green; eslint
--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.Follow-up: test-quality round from the review (head 726e230)
The review round on the api-wiring unit named four test-quality issues; the ones present in this unit are fixed here: the
viewStatesdescribe block moved out of thealwaysDenyUnapprovedCommandsblock (test names carried the wrong subject), the prune test'stoBeDefined()survival checks replaced with exact-shapetoEqualassertions (they pass even if pruning strips fields), the stale-temporary-entry test's fixed 10 ms wait replaced with awaiting the load itself (the negative assertion could pass vacuously on a slow load), and the readiness-cancel test's fake timers restored in afinallyblock (a failed assertion left fake timers active and hung a later real-timer test).Proofs: global-settings 9/9 where present, ClineProvider.spec green, sticky-mode green where present, api-task-control green where present; negative controls: pruning that strips
updatedAtreddens exactly the prune test, aloadViewStatethat adopts the unowned temporary-id entry reddens exactly the stale-entry test, restores byte-exact (hash match); eslint--max-warnings=0clean (src and types); prettier merge-ref gate ALL-MATCHED.Follow-up: review-round fixes from the series (head f528dcc)
A review round on the mode-profile-writes and e2e-view-state units found fixes this unit carries. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
A review round on the mode-profile-writes unit found that the profile-deletion re-pin updated each sibling view's buffer but not its running task: the posted state prefers the task's own
apiConfiguration, so a conversation in a view pinned to the deleted profile kept sending the deleted profile's settings. The re-pin now rebuilds the sibling's API handler with the replacement's settings and re-points the task's sticky profile name, mirroring the activation path.Proofs: ClineProvider.spec and sticky-mode green; eslint
--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED. The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.In addition: The view-state readiness bound no longer rejects headless callers whose webview never launched (it only rejects when the webview has launched and readiness failed), and the IPC start-task listener catches rejections since the IPC server does not await async listeners (new headless-fallback and launched-stuck tests; negative control: an unconditional timeout reddens exactly the fallback test). The readiness-cancel test now pins the bound's own timer via fake timers and a zero timer count instead of a global
clearTimeoutspy, and the mode-ordering test asserts the switch has not been called before the pending initialization is released (negative controls: dropping the timer clear / the initialization await reddens exactly the respective assertion).Proofs: ClineProvider.spec 299/299, sticky-mode 34/34, parallel-mode 40/40, Task.spec 190/190, api-task-control 26/26; every negative control reddens exactly its target test and restores byte-exact (hash match); eslint
--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.Updated this round (CodeRabbit follow-up, head 78c21d1)
taskApiConfigName === saved profile. Pinned-view overlays still refresh; regression tests cover both sites (negative control: removing either guard reddens exactly its test).afterEachnow disposes the per-test provider before resetting the instance registry, so providers leaveMcpServerManager's static provider set between tests.Updated this round (CodeRabbit follow-up 2, head 41bbc27)
taskApiConfigName === deleted profile(the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.Stryker suppression comments removed

Upstream refactoredupsertProviderProfileinto a newpersistProviderProfilemethod and added arunToCompletionqueue option; this unit's transactional body was ported into the new method unchanged and upstream'sPromise.allSettledactivation fix was adopted in it. ClineProvider.spec, webviewMessageHandler.spec,tsc --noEmit, eslint (suppression counts unchanged) and prettier re-verified green at this head. The first refreshed head's windows unit-test lane caught that upstream's newupdateProfileModeltests inClineProvider.apiHandlerRebuild.spec.tsmock the settings manager with a staticgetProfile, which starves the post-save read-back; the mock now repointsgetProfileat whatsaveConfigwrote (the real manager's behavior), and the file's 38 tests pass locally alongside the rest of the verification set.
