📝 SummarySummary by CodeRabbit
WalkthroughThe change adds cross-window liveness tracking for delegated child tasks. Startup and periodic reconciliation now skip recently modified or locally owned children, while stale or unreadable children are repaired. Repair-intent replay uses the same guard, with expanded lifecycle modeling, provider wiring, typing updates, and tests. ChangesDelegated task recovery
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This change strengthens reasoning-history test assertions, while the broader delegated-task recovery work still has unresolved concurrency and coverage risks that could interrupt a live child task or leave recovery behavior insufficiently protected. Resolve or explicitly accept these risks before merge. Sequence Diagram(s)sequenceDiagram

Assert the unsupported and omitted supportedParameters cases.
parseOpenRouterModel returns an array only when supportedParameters includes "reasoning" and otherwise returns undefined. The existing non-reasoning and omitted-input cases do not assert supportsReasoningEffort, so a regression could enable reasoning for unsupported models without failing this suite. Assert undefined for both cases.

Replace the new any test-double types. Repository guidance requires typed test doubles. Define minimal prop types and narrow unknown before dispatching extension messages. These annotations remove compile-time checks at the mock boundaries.

Assert removal of the registered handleMessage callback.
This test still passes if removeEventListener is deleted. After unmount, the DOM assertion remains true, and the idle handleMessage callback does not throw. Without cleanup, the callback remains reachable; when unmounted during Loading, it can update state and invalidate both router-model caches. Repeated refreshStatus changes can also accumulate handlers. Spy on both methods and assert that removeEventListener("message", ...) receives the exact callback registered by addEventListener.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Correlate model refresh responses before updating refresh state.
ApiOptions starts an unscoped useRouterModels() request while OpenRouter can start a scoped manual refresh. The shared handler emits responses without request identifiers. Either response can therefore complete or fail the manual refresh while it is loading. Add request correlation or serialize these requests at the shared boundary.

getChildFileMtimeMs and immediately before repairActiveDelegation; skip the
repair when ownership was claimed during the await.
In `@src/core/webview/__tests__/ClineProvider.markLocallyActive.spec.ts`:
- Around line 197-200: Update the success and rehydrate tests around
markLocallyActive and taskScheduler.schedule to assert invocation order,
verifying the local claim occurs before scheduling rather than only checking
both calls afterward. Use the mocks’ recorded invocation order and preserve the
existing call-count assertions.
In `@src/core/webview/ClineProvider.ts`:
- Line 179: Add regression tests around the task-ownership flow in
ClineProvider, forcing performPreparationTasks to throw and
TaskScheduler.schedule to reject, and assert the task ID is marked locally
active once and locally inactive once. Also cover successful, cancellation, and
startTask: false compatibility paths to verify ownership is not released
prematurely, including the onScheduleFailure path.

…lineProvider.ts What: replace every explicit-any site with precise domain types — super.on/off via base EventEmitter signature assertion (documented @types/node deferred-conditional limitation), params via Record<string, string | DiagnosticData[]>, _taskMode via AGENTS.md bracket access, apiConfiguration/mode/parent casts deleted (redundant), parentApiMessages typed as ApiMessage[]. Delete the core/webview/ClineProvider.ts entry from eslint-suppressions.json (count 12 -> 0, tab format preserved). Also stub missing markLocallyInactive on the flicker-free-cancel spec's taskHistoryStore double to remove 5 pre-existing unhandled rejections (mirrors TaskHistoryStore.markLocallyInactive and remote commit e90c99a). Why: VS Code ESLint extension does not read eslint-suppressions.json, so the editor showed 12 red no-explicit-any squiggles despite CI passing; user requires zero editor diagnostics. Pure type-space refactor — emitted JS verified byte-identical. Verification: eslint --max-warnings=0 exit 0; tsc --noEmit exit 0; vitest run core/webview 484/484 with 0 unhandled errors; prune-suppressions leaves entry removed.
What: replace every explicit-any site with precise domain types — providerRef target typed as ClineProvider (cast deleted, method public), tool-use .id writes uncast (id?: string exists on ToolUse), getCurrentProfileId param typed via Pick<ExtensionState, ...>, backoff error typed via minimal BackoffApiError structural interface, reasoning summary items derived from OpenAI SDK ResponseReasoningItem with the existing ReasoningDetail domain type, and two pure narrowing helpers replacing the (first as any) chain. Delete the core/task/Task.ts entry from eslint-suppressions.json (count 17 -> 0, tab format preserved). Why: VS Code ESLint extension does not read eslint-suppressions.json, so the editor showed 17 red no-explicit-any squiggles in Task.ts despite CI passing; user requires zero editor diagnostics and zero remaining problems. Pure type-space refactor. Verification: eslint --max-warnings=0 exit 0 (Task.ts and ClineProvider.ts); tsc --noEmit exit 0 project-wide; vitest run core/task 35 files / 569 tests, 0 unhandled errors.
…anup What: add three focused specs — getCurrentProfileId return assertions (kills 4 Survived + 6 NoCoverage on profile lookup), buildCleanConversationHistory reasoning-block cleaning coverage (kills 25 NoCoverage across encrypted/plain-text/standalone/passthrough paths), and backoffAndAnnounce RetryInfo extraction (kills 7 NoCoverage on 429 retry-delay parsing). Add a Stryker OptionalChaining disable directive with justification on the getCurrentProfileId find callback: removing the inner state?. is a provably equivalent mutant (the callback only executes when state is non-nullish, and undefined state returns "default" via the outer short-circuit). Why: the Task.ts type-cleanup commit brought these lines into the CI mutation gate's changed-code scope; the gate fails with 43 blockers until covered. Private methods exercised via the existing Object.create(Task.prototype) bracket seam used by sibling specs; no production behavior change. Verification: vitest run core/task 38 files / 591 tests 0 unhandled; eslint core/task --max-warnings=0 exit 0; tsc --noEmit exit 0; local gate Task.ts tally Killed 3->45 Survived 4->1 NoCoverage 39->0.

… checks
What: add not.toHaveProperty("id") at the three sites in Task.buildCleanConversationHistory.reasoning.spec.ts where key-absence is the claim being pinned (encrypted-split enc-2 case, solo reasoning enc-3 case, standalone no-id case), keeping existing toEqual assertions. Kill-strength proven by hand-mutation: flattening Task.ts conditional id spreads (L5005/L5059) yields 0/3 failures on the old assertions and is caught by the new checks.
Why: vitest toEqual treats an undefined-valued id key as absent, so the previous assertions could not distinguish the real object from one carrying id: undefined; a conditional-spread mutant would pass silently. Addresses CodeRabbit round-5 finding 1 (verified valid); findings 2-3 were skipped as invalid with causal-chain proofs (active-status persist precedes the ownership claim; run()-rejection ownership retention is the ratified crash-orphan policy).
