Full details: Regression EvidenceExplanation Focused coverage is incomplete for the new readiness behavior. Resolution Add provider-level regression tests for delayed migration through both Full details: Persistence IntegrityExplanation The new readiness gate treats a failed migration as successful. Resolution Do not resolve the readiness gate as a normal success after initialization or migration failure. Propagate the failure or retry migration before allowing these consumers to proceed. Keep the migration marker unset until all entries and repairs succeed, and make the mode/profile mutation paths fail or retry instead of silently treating a missing store item as a successful persistence path. Preserve a verified legacy-source fallback during a failed migration if standalone recovery is required.

- Line 2247: Gate the task-history lookups in the mode path, provider-profile
path, and getTaskWithId around taskHistoryStore.get(id) on a provider-level
readiness promise that resolves only after ClineProvider completes legacy
globalState migration. Replace reliance on taskHistoryStore.initialized for
these paths, ensuring delayed migration still allows updateTaskHistory() and
getTaskWithId() to find legacy tasks; add regression coverage for this
delayed-migration scenario.

taskHistoryStore.initialized resolves in a finally before migrateFromGlobalState finishes, so the task-history lookup paths in ClineProvider (mode switch, sticky provider profile, getTaskWithId) could observe the pre-migration window and miss legacy tasks that the removed globalState fallback used to serve. Add a provider-level readiness gate that settles only after initializeTaskHistoryStore (including legacy migration) completes or fails, and await it in the three lookup paths. Add a regression test covering a delayed migration.

Propagate task-history initialization failures to the gated readers.
initializeTaskHistoryStore catches failures from TaskHistoryStore.initialize() and migrateFromGlobalState(), then resolves taskHistoryStoreReady in finally. The constructor has no retry. If migration fails before a legacy item reaches the cache, getTaskWithId() throws "Task not found". The mode-switch and sticky-profile readers can also skip persistence for that task. Reject the readiness state and make all three readers surface or retry the initialization error. Add a regression test for a rejected migrateFromGlobalState() call.

Closes: #1543
Description
Removes the three dead
context.globalState.get("taskHistory")fallback reads inClineProvider.ts(handleModeSwitchUnlocked, provider-profile-switch persistence, andgetTaskWithId).Why they're dead:
initializeTaskHistoryStore(run at construction, before any webview state is served) performs a one-time, idempotent migration of legacy globalState entries into the file-backedTaskHistoryStore, andTaskHistoryStore.get(in-memory cache over per-task files) is the source of truth. After migration, the fallback can never serve a case the store doesn't already cover.Deliberately untouched: the migration's own read (
globalState.get("taskHistory")as migration source) and theupdateGlobalState("taskHistory", …)write-through — the latter belongs to the sibling issues/PR (#1541/#1542, PR #1664) and is out of scope here, per this issue's "safe to merge standalone" note.Test Procedure
getGlobalState("taskHistory")as the sole history source): 6 inClineProvider.sticky-mode.spec.ts, 2 inClineProvider.spec.ts(getTaskWithId). Updated to feed the primary path via typedvi.spyOn(provider.taskHistoryStore, "get")— zero assertion changes, and the change removed 6 now-unneededas anycasts (suppression count 37 → 31 for that file, exactly the removed casts; no other counts touched).cd src && ./node_modules/.bin/vitest run core/webview→ 28 files / 505 tests passed.cd src && pnpm run check-types→ 0 errors.Pre-Submission Checklist

Additional Notes
Behavior note (matches the issue's intent): if
getTaskWithIdwere ever called beforetaskHistoryStore.initialize()resolves, it now throws "Task not found" instead of silently finding a legacy globalState entry — the only production caller of that kind (IPCResumeTask) catches and logs the error gracefully, and all webview flows operate on store-built task lists.Get in Touch
