test(webview): F2a - profile-mutation state semantics and the mode-rollback guard - #1919

Conversation
…en view-identity tests Track the in-flight tab panel creation with a module-level promise so concurrent openClineInNewTab calls reuse one panel and provider (adds a Promise.all regression test). ClineProvider.spec sets the private view via the public resolveWebviewView() instead of a ts-ignore assignment. registerCommands.spec types evictCurrentTask/refreshWorkspace on the fixture and drops the as any attachment. eslint-suppressions: prune the registerCommands.spec.ts entry (two as any suppressions removed).
…n the concurrency assertion
…-bar posts - openClineInNewTab: extract the unserialized creation body into createTabPanelUnlocked and guard the in-flight slot clear so a settled creation cannot clobber a replacement already stored in the slot. - onDidDispose: clear the tracked tab ref only when the disposing panel is still the tracked one, so a late disposal of a replaced panel cannot clobber the replacement's ref. - MDM lookup failure: log the fallback to the output channel instead of swallowing it silently. - Route the six title-bar button handlers through a shared postActions helper that posts each action in order and logs failures with the handler-specific prefix. - package.json: add the four InTab commands to the command palette, scoped to the active tab panel. - Tests: handler-level regression for openInNewTab + popoutButtonClicked started before the first creation resolves; fresh-creation test for a settled in-flight promise; stale-panel disposal regression; retained panel assertion for disposed tab instances; rightmost-editor column placement assertion; MDM fallback output assertion; %s placeholders for primitive it.each titles. - Stryker directives for the two equivalent setPanel type-literal mutants (setPanel branches only on type === sidebar).
Replace the weak toBeDefined() assertion in the dispose spec with an identity check against the panel returned during creation, per the CodeRabbit actionable comment on this PR (review run 7c4cfeb3-6dd9-4615- 9a58-70cfc705eca2). The tracked tab is now pinned with toBe(panel) before the dispose assertions, so a wrong or duplicated tracked panel fails the suite instead of passing a defined-only check. Upstream: Zoo-Code-Org#1528 (vps2 F0)
Retain the tracked tab panel in the InTab handler cases and assert that getInstanceForView was called with that exact panel, per the CodeRabbit actionable comment on this PR (review run 4afe1273-8739-4235-90d3-311db5f6ccb9, inline comment 3952466254 on the tabHandlerCases spec). A handler resolving any other view now fails instead of passing on the stubbed provider result alone; the same identity pin is applied to plusButtonClickedInTab. Upstream: Zoo-Code-Org#1528 (vps2 F0)
…States Each ClineProvider instance now owns a unique viewId (renderContext plus a monotonic counter) and registers a stable viewStateId for durable persistence. - Per-view state buffer (viewLocalState) holds mode / currentApiConfigName / apiConfiguration overrides in memory; saveViewState persists the non-secret subset durably under the active view id, rekeyed to the stable id on registration. - viewStates is stored as a map pruned to the newest 50 entries; writes go through a serialized queue so concurrent provider instances merge without lost updates. - setViewStateId sanitizes ids and rejects "__proto__" so a per-view entry can never be keyed through the Object.prototype setter. - postMessageToWebview no longer awaits the webview ack: a remounted or disposed page never acknowledges, and awaiting would wedge task-critical callers. - History restore falls back to the default mode view-locally instead of writing the shared global mode. - GlobalState gains the "viewStates" key and GLOBAL_STATE_KEYS tracks it. Adds F1a coverage in ClineProvider.spec.ts (viewId uniqueness, saveViewState persistence semantics, loadViewState fallback and failure, pruning, the __proto__ guard) and adapts the two history-restore tests in ClineProvider.sticky-mode.spec.ts to the view-local restore. getState() merging of hydrated per-view values and the remaining view-state suites land in the follow-up (F1b).
…lude viewStates from settings transfer
…ions through the view-local buffer
…nd target tab-instance commands Reapply in-flight view-local fields with Object.is identity so a field cleared during the load window stays cleared; route mode switches through setValue so the in-memory buffer and durable write agree, with rollback on failure; refresh cross-instance view-local state on profile upsert, activate and delete and re-pin the buffer after a delete; point focusInput and active-panel re-registration at the tracked tab provider and panel; log dropped webview postMessage failures with the message type; pin tab-instance, focusInput and active-panel identity in the registerCommands tests and type the mdm double in the provider spec.
…apture view pin on delete Address CodeRabbit walkthrough findings on the F1a unit: - handleModeSwitchUnlocked now bails before the task-level writes when the abort signal has fired, closing the partial-apply window where a cancelled switch could still rewrite the persisted task mode; the existing pre-write guard still covers in-flight aborts. - Replace bracket access to sibling-instance private members with a typed pinnedProfileName getter and direct private member access (compile-time safe across instances). - deleteProviderProfile now captures this view's pin before the currentApiConfigName rewrite so a view pinned to the deleted profile while the global selection points elsewhere is still reconfigured with the surviving profile's settings. Tests: focusInput asserts the tab panel by identity and that no error was logged on the success path; the stalled getProfile double fails loudly on a second lookup (only one lookup is resolvable).
…-local profile pins
handleModeSwitchUnlocked: an abort landing while updateTaskHistory is in flight previously left the new mode persisted in task history and assigned to task._taskMode before the pre-write signal check bailed; the landed write is now rolled back to the pre-switch item and the method returns before the TaskModeSwitched emit and the durable mode write. TaskModeSwitched now only fires for a completed transition. deleteProviderProfile: the unconditional setValue('currentApiConfigName', ...) overwrote a view's pin when an unrelated profile was deleted; the pin is now re-pointed only when it names the deleted profile, and a deleted-was-global deletion updates the shared store only. The nested apiConfiguration overlay is replaced with the surviving profile's settings only for a view pinned to the deleted profile.
…tore deleteProviderProfile pruned the UI-facing listApiConfigMeta entry but never removed the profile's settings from the ProviderSettingsManager store (context.secrets), so a later listApiConfigMeta sync could resurrect the deleted profile and a dangling per-mode mapping could re-activate it. The purge now calls providerSettingsManager.deleteConfig and branches on the typed ProviderSettingsNotFoundError (introduced here alongside) so an already-gone secret is an idempotent success -- the stale list entry is still pruned -- while any other failure (e.g. the store refusing to delete the last remaining configuration) propagates. Matching message text instead would let a profile whose name contains 'not found' swallow an unrelated failure. Tests: the dangling-mode-mapping resurrection scenario, the already-gone secret, the store-level last-profile refusal, the typed-signal contract in the manager spec, and provider-level not-found/propagation pins.
A failed task-history rollback during an aborted mode switch previously propagated into the outer persistence-error handler and surfaced as the switch's own persistence failure. Guard the rollback with its own try/catch so the rollback error is logged with task context and the cancellation return is preserved (CodeRabbit finding on this PR).
…d switch The in-flight abort rollback rewrote the whole task-history item with the pre-switch snapshot, clobbering any fields the running task persisted during the pending window (tokens, cost, status, apiConfigName). Re-read the item and restore only the mode this switch changed (CodeRabbit data-integrity finding on this PR).
Rebasing onto main tip merged main's createTabPanelUnlocked body with the PR's serialized creation. Main no longer resolves CodeIndexManager in this function, so the leftover line referenced an import the PR never added and the suite failed with ReferenceError. Removing it restores the PR's own delta: 48 registerCommands tests and 459 F1a tests pass.
…overrides Fold ClineProvider viewLocalState on top of ContextProxy values in getState() (mode, apiConfiguration, and all per-view fields) so each webview reports its own selections while falling back to shared global state for everything else. Ports the getState-merging and local-state-isolation spec coverage from the superseded vps2 source. Also pins the full default surface of the merged read path, including the apiConfiguration provider fill-in when provider settings sanitize the raw value away (mutation-diff gate).
Rebuilding the F1b unit as main tip + its own delta cleared the conflict with main. The patch was authored against an older main, so applying it dropped the alwaysDenyUnapprovedCommands entry from getState(); restoring it with the shared default constant keeps the settings round trip complete. 410 tests pass.
Applying the F1c delta (ad94239...8554307) onto the rebuilt F1b head cleared the conflict with main tip without changing content. 338 src tests and 39 webview-ui tests pass.
…llback guard Part of the vps2 durable per-view state series, tracked in #41. Stacked on F1c. Content ported from the pinned source (kind: commit, base 8554307 -> head bff2a5c, PR Zoo-Code-Org#1555).

Explanation
The prior secret-disclosure finding remains unresolved in changed code.
webviewDidLaunchpasses the webview-controlledmessage.viewStateIdtoClineProvider.setViewStateId(src/core/webview/webviewMessageHandler.ts:603-615). The host checks only format, length, and IDs held by live providers (src/core/webview/ClineProvider.ts:852-897).dispose()removes the old provider fromactiveInstances(src/core/webview/ClineProvider.ts:1360-1367) but preserves its durableviewStatesentry, so a different provider can adopt a known closed-view ID.loadViewState()then loads that entry and callsgetProfile(src/core/webview/ClineProvider.ts:950-958), and launch posts the resultingapiConfigurationthroughgetState()(src/core/webview/ClineProvider.ts:4781-4790,src/core/webview/ClineProvider.ts:4201-4205). Provider profiles include secrets in secret storage (src/core/config/ProviderSettingsManager.ts:459-492,774-780). A compromised webview that knows a closed view's ID can therefore cause the extension host to load and post that view's profile secrets to the wrong webview.Resolution
Bind each stable view-state ID to its owning extension-host webview, or use a host-minted capability that the webview cannot choose. Reject IDs that are not issued or bound to the current provider before loading or re-keying persisted state. Preserve only a controlled reload or re-adoption path. Add a regression test that disposes the original provider, sends its known ID in
webviewDidLaunchon another provider, and verifies that profile settings and secrets are not loaded or posted.
Full details: Persistence Integrity
-
Explanation
Changed deletion re-pin persistence still lacks rollback for task history.
rePinViewLocalStateForDeletedProfilewrites each affected task'sapiConfigNameatClineProvider.ts:3768-3773, then posts state at:3774. If a later post rejects, the helper rejects and deletion compensation restores view-state/profile stores at:3254-3338, but it never restores the task-history write.persistStickyProviderProfileToCurrentTaskpersists throughtaskHistoryStore.upsertat:3424-3428and only changes the in-memory pin during compensation. A failed deletion can therefore restore the deleted profile while the task history still points to the replacement profile. Also, if that task-history write itself fails,:3429-3435logs and allows deletion to commit, leaving durable task history pointing at the deleted profile. The closed-view repoint added at:3249-3253addresses the earlier stale closed-pin path, but it does not address these task-history outcomes.Resolution
Make deletion re-pin a compensating transaction for task state. Snapshot each affected task's prior in-memory and persisted
apiConfigName, include task-history writes and state posts in the protected operation, and restore every landed task-history record and task on any later failure. Surface restore failures as an explicit inconsistent-state error. If a task-history write fails during a committed deletion, either roll back the deletion or report the partial state instead of swallowing the error and continuing.
Full details: Regression Evidence
-
Explanation
The prior regression remains unresolved.
src/package.jsonchanges the visibleeditor/titlemenu for an activezoo-code.TabPanelProviderto four new tab-specific commands (plusButtonClickedInTab,settingsButtonClickedInTab,marketplaceButtonClickedInTab, andhistoryButtonClickedInTab). The PR changes noapps/vscode-e2evisual test or snapshot files. The existing Electron visual test captures only.part.sidebarand selected webview frames, and its scene controller supports onlywelcomeandchat. The routing unit tests do not capture the visible title-bar surface.Resolution
Add a Playwright Electron visual test that opens an active
zoo-code.TabPanelProvider, waits for the editor title bar, and captures a deterministic snapshot containing the New Task, Settings, Marketplace, and History actions. Commit the baseline snapshot. Keep the existing routing unit tests.
Full details: Lifecycle Resource Cleanup
-
Explanation
The lifecycle leak remains in the changed tab-creation path.
createTabPanelUnlockedconstructsClineProvideratsrc/activate/registerCommands.ts:395-402, before the cleanuptryat line 406. The constructor adds itself toClineProvider.activeInstancesatsrc/core/webview/ClineProvider.ts:467and createsWorkspaceTrackerat line 490.WorkspaceTrackerregisters a file watcher and tab listener at lines 42-73. If constructor initialization throws after those side effects, no provider object reachesdisposeFailedTabCreation, so the watcher, listener, and registry entry can remain. The shared creation promise then clears inopenClineInNewTab, and a retry can create another provider and another set of resources.Resolution
Use constructor-safe cleanup. Track each resource during provider construction, or use a factory that can roll back partial construction. On synchronous constructor failure, remove the provider from
activeInstances, disposeWorkspaceTrackerand every other initialized resource, clear any panel reference, preserve the original error, and keep retry cleanup safe.

- Around line 3318-3320: In refreshViewLocalStateForUpdatedProfile, defer
updateTaskApiHandlerIfNeeded calls until all sibling buffer writes and
postStateToWebview calls succeed, so a failed refresh cannot leave a task
handler using rolled-back settings. Add a regression test with a healthy sibling
task pinned to the profile and another sibling whose post rejects; assert the

Learning: In Zoo-Code's durable per-view state series, the provider-profile mutation queue in src/core/webview/ClineProvider.ts is per instance. Cross-provider atomic updates of listApiConfigMeta require coordination across every writer, not only deletion compensation. The maintainer places that contract redesign at chain level, outside the F2a unit. Do not treat re-reading the list and splicing the deleted profile back as an atomic merge at commit time.

Learning: In Zoo-Code's durable per-view state series, the provider-profile mutation queue in src/core/webview/ClineProvider.ts is per instance. Cross-provider atomic updates of listApiConfigMeta require coordination across every writer, not only deletion compensation. The maintainer places that contract redesign at chain level, outside the F2a unit. Do not treat re-reading the list and splicing the deleted profile back as an atomic merge at commit time.

profile’s stored settings to `repointViewLocalStateAfterProfileRename` instead
of `normalizedRenamed`, so affected views restore the old settings when their
selection returns to `oldName`.
- Around line 2485-2496: Before calling repointViewLocalStateAfterProfileRename,
snapshot the existing newName record and the exact persisted and live state of
views it will affect. If repointing fails, restore the prior destination record
(or remove newName only if it was previously absent) and independently restore
each affected pin, overlay, task handler, and sticky profile name; report any
restoration failures as an inconsistent-state error rather than discarding them.
Keep this compensation in the failure path before deleteConfig(oldName).

…ck view-state maps, and re-point closed views on deletion
# Conflicts: # src/core/webview/ClineProvider.ts
…get names - Reject a rename whose target name already exists before saving: webview name validation lets a case-only collision reach the handler, and the rollback would otherwise delete a record the rename never owned. - Keep the pre-rename stored record and roll the views back to it when the old-name deletion fails, instead of the attempted payload that was never persisted under the old name. - Undo the rename's own save when the normalized read-back or the view re-point fails, so a failed rename cannot leave both names resolving to the same id. - Log failed rename compensation instead of discarding it.

A rejected durable re-point left live siblings already re-pointed in memory while the compensation restored only the shared stores: their buffers served the survivor until their next mutation while the restored durable entries named the deleted profile again after a reload. Running the re-point first leaves every view - live and closed - on the restored profile when the write rejects.
… failed deletions - Re-read the stored record after saveConfig and fail the upsert when the read-back fails, compensating the landed save with the pre-save snapshot instead of letting an unvalidated caller payload drive activation writes. - Snapshot the manager record and every persistence surface before deleteProviderProfile commits its manager delete, and restore them (record, profile-list merge, selection, shared settings, affected view pins) when a later write in the deletion group fails. - Keep the mutation queue owned by a mode switch past its timeout via runToCompletion so the next queued mutation cannot overlap in-flight writes.
The outer write-group restore must not roll back a replacement activation failure (the deletion has committed by contract) and must not run a second compensation after the scoped activation rollback already ran. Guard both with a rethrow, strengthen the activation-failure test with a saveConfig spy, and re-key the cancelled-deletion double for the snapshot read.

This unit does not close an upstream issue: it is split unit F2a of the durable per-view state (vps2) series, whose split plan is issued and tracked on (issued before this PR opened). It supersedes the closed umbrella PR 1555, and merges in the chain order F1a 1546 → F1b 1550 → F1c 1552 → F2a → F2b → F2c 1921.
Description
Content source of record:
kind: commit, base8554307ec→ headbff2a5ca8(PR 1555), replayed onto the currentmaintip so the branch carries nothingmainalready has.Budget (own delta, not the stacked view): 173 a+d standalone, 12 changed executable lines.
One gate scope: the state semantics of a profile mutation must hold for every live view, not only the view that performed it, and a mode rollback must not be able to persist a profile that no longer exists.
apiConfigurationof every other liveClineProviderpinned to that profile (refreshViewLocalStateForUpdatedProfile) and re-posts each affected view's state, so no view keeps serving — or running on — settings it buffered before the mutation.rePinViewLocalStateForDeletedProfile), replaces their configuration with the surviving profile's, and persists the replacement through the serialized write queue so their durableviewStatesentries survive a reload.deleteProviderProfilenow writes only the profile list back instead of replaying a full settings snapshot, so it cannot clobber unrelated keys (notablyviewStates) that concurrent views mutate directly.Also in this head (
1b9d6d73f), from review:deleteProviderProfileperforms two durable writes — the settings-store commit and the profile-list write. If the list write (or a later selection update) fails, the stored list still names a profile whose settings are gone and no later selection or load can recover them. The settings are now captured before the commit and written back throughsaveConfigwhen a later step fails, so the durable metadata and the store agree again (the deletion simply did not happen); the original error is rethrown and a failed compensation is logged with the residual risk stated.Reviewer focus: the compensation is deliberately a settings restore, not a list rollback — the list write is the step that failed, so the list keeps naming the profile and the store is made to agree with it. Restoring the original
idmatters: a new id would orphan the task history entries that reference the profile.Test Procedure
New/updated tests in
core/webview/__tests__/ClineProvider.spec.ts:getState(), and that its webview was re-posted.viewStatesentry.saveConfigis called with the original id and secret while the original error propagates.Each is verified as a pin, not a mirror of the implementation: the two cross-view tests fail when the helper bodies are made to return early, and the compensation test fails when the production change is stashed.

vitestlanes run fromsrc/. Local result at this head:ClineProvider.spec.ts283 passed (280 baseline + 3 new);tsc --noEmitunchanged from this branch's local baseline; eslint clean on both touched files with unchanged suppression counts.Pre-Submission Checklist
No documentation change: the user-facing flow (activate / edit / delete a provider profile) is unchanged; only the state each live view ends up with, and the durability ordering inside deletion, changed.
Split-unit issue reference
No approved upstream issue exists for this change. This pull request is one unit of a declared split of a larger change, and the split plan, the unit boundaries and this unit's acceptance criteria are recorded on the tracking issue in this repository: #1992. That issue is the home for this unit's review dispositions and follow-up registrations, which is why no approved issue is linked above.
AT-HEAD review walkthrough triage (head 8a43f2b)
All 31 review threads are resolved. The nine latest AT-HEAD walkthrough rows were re-verified against this head:
viewIdadoption (ClineProvider.tsload/rekey) - addressed:rekeyPersistedViewStateEntrytreats temporary ids as session counters; a stable entry wins and the temporary entry is dropped, so an unrelated earlier view's entry is not adopted as a stable rekey.undoHistoryWriteassigned without a landed history write - addressed: the closure is a no-op when no history item existed before the switch, and the comment matches the code.deleteApiConfiguration->activateProviderProfilepath (Major) - fixed at 8a43f2b: the deletion now completes the activation-side effects when the deleted profile was the active one (globally or for this view): the manager's own current-profile record and the current mode's profile mapping follow the survivor, the current task's API handler is rebuilt from the survivor's settings, the current task's sticky profile is refreshed, andProviderProfileChangedis emitted. Placement mirrorsactivateProviderProfileUnlocked: after the try/catch, because the deletion has committed. Proofs in the thread reply.openInNewTabcalls (Major) - addressed: the handler unconditionally creates a new panel viaopenClineInNewTab; the tracked-panel reveal is not on the settled path.*InTabvariants, which target the tracked tab instance and are meaningless from the palette, are hidden withwhen: false; the sidebar variants are registered once at activation and target the activation-wired provider directly (no per-view registration, no visible-instance heuristic), which is the pre-unit palette behavior.Verification numbers (head 8a43f2b)
Post-commit activation error distinction (head 91dfd64)
errors.delete_api_config, misreporting a successful deletion. Fixed: the committed state is posted first, then a distinctProfileDeletionActivationError(own moduleprofileDeletionError.ts, re-exported by the provider) is thrown; the handler warns with the activation cause instead of the generic delete error.CI re-trigger: heads e704ab4 and 67a9649 are empty commits over 91dfd64 (no content change) to re-run flaked lanes; the visual lane passed at e704ab4, and 67a9649 re-runs the mock-e2e 30s-timeout flake ('persists completed task across a fresh extension host' - the identical tree passed e2e-mock at 91dfd64). All verification numbers above apply unchanged.
Pre-merge ERROR-row pre-check (head d5c69d3)
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)._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.rePinViewLocalStateForDeletedProfilere-pins other live views still buffered on a deleted profile (buffer + durable entry), and deletion snapshots/compensates every store it rewrites.

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

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

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 acfd9ae)
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.Updated this round (port of the two upstream PR 1921 review fixes)
acfd9ae -> 54b3890
Ported the two fixes landed on the sibling unit (fork PR 43 / upstream PR 1921 at 2e932e8). This unit carries the same shared code (provider-profile mutation queue + sibling re-pin), so the same review findings apply to this branch:
providerProfileMutationQueueis now shared across instances (static). The per-instance queue let a second view commit between this view's shared write and its snapshot compensation, and the compensation restored a stale copy over the newer write; one queue now serializes every view's profile mutations against each other.Tests: this unit has no
ClineProvider.parallelMode.spec.ts(parallel-mode lineage), so both regression tests land inClineProvider.spec.tsnext to the existing re-pin rollback tests - cross-instance serialization + sibling-task rollback - adapted to this unit's manager-double and saveViewState pin conventions.Proofs:
ClineProvider.spec321/321 (2 new tests); sticky-mode + sticky-profile + webviewMessageHandler 143/143; negative controls: per-instance queue shadow reddens exactly the serialization test, task updates moved back into the per-sibling loop redden exactly the sibling-task test, both restores byte-exact (hash match 7c41a7db88ee1710); eslint --max-warnings=0 clean, suppression counts unchanged; tsc = 2 known donor telemetry-dist noise lines only (real 0); prettier touched files clean and the full merge-ref tree gate ALL-MATCHED @617037b1c (base 54b3890).Updated this round (CodeRabbit follow-up, head 28e969c)
taskApiConfigName === saved profile; pinned-view overlays still refresh. Regression tests cover both sites (negative control: removing either guard reddens exactly its test).Updated this round (CodeRabbit follow-up 2, head 9afc9d8)
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).Stryker suppression comments removed

resetState()now broadcasts across live providers (broadcastResetToAllInstances, the same slice this series ships in the cross-instance-reset units): the shared durableviewStatesslot is cleared once through the persisted write queue, every live view's in-memory buffer (which can hold a deleted profile's settings, API keys included) is dropped, and each sibling view is reposted. Regression test added; dropping the broadcast reddens exactly that test.saveApiConfiguration/renameApiConfiguration/getListApiConfigurationhandlers, launch-timelistApiConfigMetasync).Row-9 update (head 0dae49a)
deleteProviderProfilenow re-points persisted pins of disposed views onto the surviving profile, records the write in the landed-flags set, and rolls the exact pre-deletion map back through the serialized queue on failure (CR Persistence Integrity).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.
Upstream refresh (head 0dae49a)
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 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. One deliberate adaptation: upstream optsupsertProviderProfileintorunToCompletion; this unit does not, because its contract is the landed-write compensation - the mutation timeout must abort the run so the compensation rolls the record and the stores back, which is what the cancellation tests pin. 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. Three of upstream's new tests are adapted to this unit's abort-and-compensate upsert semantics (documented in comments): the timed-out upsert cancels and rolls back instead of running to completion, and the restore-path tests account for the compensation's record rollback and the serialized write order.
