test(webview): F2a - profile-mutation state semantics and the mode-rollback guard - #1919
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, base 8554307ec → head bff2a5ca8 (PR 1555), replayed onto the current main tip so the branch carries nothing main already 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.
Activating or upserting a profile refreshes the buffered apiConfiguration of every other live ClineProvider pinned 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.
Deleting a profile re-pins the other live views whose buffer still names it (rePinViewLocalStateForDeletedProfile), replaces their configuration with the surviving profile's, and persists the replacement through the serialized write queue so their durable viewStates entries survive a reload.
deleteProviderProfile now writes only the profile list back instead of replaying a full settings snapshot, so it cannot clobber unrelated keys (notably viewStates) that concurrent views mutate directly.
A mode-scoped profile rollback is guarded so a profile that no longer exists cannot be re-persisted.
Also in this head (1b9d6d73f), from review:deleteProviderProfile performs 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 through saveConfig when 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 id matters: a new id would orphan the task history entries that reference the profile.
Test Procedure
# from the repository root, with dependencies installed (pnpm install)
pnpm --dir src exec vitest run --globals core/webview/__tests__/ClineProvider.spec.ts
pnpm --dir src exec tsc --noEmit
New/updated tests in core/webview/__tests__/ClineProvider.spec.ts:
refreshes another live view's buffered settings when the profile it pins is reactivated — two live providers; the mutating view is a different instance, and the assertion is on the other view's buffer, its constructed getState(), and that its webview was re-posted.
re-pins another live view and persists the replacement in its durable view state when its profile is deleted — asserts the other view's in-memory pin, its replaced configuration, and the durable viewStates entry.
restores the deleted profile's settings when the profile-list write fails after the store commit — the store commit succeeds, the list write rejects, and the test asserts saveConfig is 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.
Environment: Windows 11 / Node 22, vitest lanes run from src/. Local result at this head: ClineProvider.spec.ts283 passed (280 baseline + 3 new); tsc --noEmit unchanged from this branch's local baseline; eslint clean on both touched files with unchanged suppression counts.
Pre-Submission Checklist
Issue Linked: No upstream issue is closed by this unit (see above).
Scope: One gate scope — cross-view state semantics for profile mutations, plus the mode-rollback guard.
Self-Review: Reviewed against the shipped behavior of the superseded umbrella PR 1555.
Testing: Three new focused unit tests, each verified as a pin.
Visual Snapshots: Not applicable — no rendered-state change.
Documentation Impact: None required; no user-facing setting or message contract changes.
Contribution Guidelines: Read and agreed. ### Documentation Impact
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.
All 31 review threads are resolved. The nine latest AT-HEAD walkthrough rows were re-verified against this head:
Temporary-viewId adoption (ClineProvider.ts load/rekey) - addressed: rekeyPersistedViewStateEntry treats 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.
undoHistoryWrite assigned 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.
Deletion compensation vs concurrent profile-list mutations - addressed: the compensation re-reads the stored list and splices only the deleted profile back at its previous index (test: "restores the deleted profile without dropping one another instance upserted meanwhile").
Cancelled deletion not rolled back after the settings commit - addressed (a591a1e): the catch routes every failure, including cancellation, through the compensation; the superseded-contract comments were corrected.
Deleting the active profile dropped the live-state half of the old deleteApiConfiguration -> activateProviderProfile path (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, and ProviderProfileChanged is emitted. Placement mirrors activateProviderProfileUnlocked: after the try/catch, because the deletion has committed. Proofs in the thread reply.
Multi-tab creation for settled openInNewTab calls (Major) - addressed: the handler unconditionally creates a new panel via openClineInNewTab; the tracked-panel reveal is not on the settled path.
Queue advance contract (Major) - addressed: the queue is deliberately chained to the full run - holding the queue until the run settles is what makes the rollback safe - and the comments describing the superseded contract were corrected.
Sidebar-only title commands visible in the command palette - addressed (6cc68ef, within the marked range): the *InTab variants, which target the tracked tab instance and are meaningless from the palette, are hidden with when: 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.
Deletion compensation vs other provider instances (Major) - addressed: same merge-style restore as row 3, with a one-to-one negative control.
AT-HEAD thread 4251990874 (Minor, functional correctness): a rejection in the post-commit activation block was reported by the message handler as errors.delete_api_config, misreporting a successful deletion. Fixed: the committed state is posted first, then a distinct ProfileDeletionActivationError (own module profileDeletionError.ts, re-exported by the provider) is thrown; the handler warns with the activation cause instead of the generic delete error.
Proofs at 91dfd64: ClineProvider.spec 317/317, webviewMessageHandler.spec 92/92 (new tests both sides); negative controls 1-red each, restores byte-exact (hash match); tsc clean except the two known local telemetry-dist noise lines; eslint clean; prettier merge-ref gate ALL-MATCHED. Ported to the sibling unit carrying the same deletion code.
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.
Security Boundaries / view-state id rows: addressed at d5c69d3. 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).
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.
Deletion sibling-state: addressed - rePinViewLocalStateForDeletedProfile re-pins other live views still buffered on a deleted profile (buffer + durable entry), and deletion snapshots/compensates every store it rewrites. Re-key persistence: single queued write, temp entry survives a failed write.
The three shared-view handoff tests now dispose the writer before the next view adopts the id (the ownership rule being enforced); the durable entry stays in storage across the handoff.
Proofs at d5c69d3: sticky-mode 33/33, ClineProvider.spec 317/317, webviewMessageHandler.spec 92/92; 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 bf474cd: 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 7b107d3)
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 eda590a)
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 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=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.
Updated this round (port of the two upstream PR 1921 review fixes)
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:
providerProfileMutationQueue is 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.
The sibling re-pin now switches each view's task (API handler rebuild + sticky profile name) only after every sibling's re-pin landed. Running those updates inside the per-sibling loop left a successful sibling's task on the replacement's handler and sticky name while its pin was compensated back to the deleted profile after a later sibling's rejected re-pin rolled the deletion back.
Tests: this unit has no ClineProvider.parallelMode.spec.ts (parallel-mode lineage), so both regression tests land in ClineProvider.spec.ts next 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.spec 321/321 (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)
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).
Test hygiene: prune assertions compare full kept entries; the webview state-payload test renamed to describe what it asserts.
Updated this round (CodeRabbit follow-up 2, head 9afc9d8)
Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite (post-loop task pass in this unit's compensated re-pin) 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).
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,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
resetState() now broadcasts across live providers (broadcastResetToAllInstances, the same slice this series ships in the cross-instance-reset units): the shared durable viewStates slot 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.
Corrected the stale "per instance" queue comments (compensation path and its test): the queue is static and serializes provider-profile mutations across views; the remaining hazard is the queue-bypassing profile-list writes (saveApiConfiguration/renameApiConfiguration/getListApiConfiguration handlers, launch-time listApiConfigMeta sync).
Deletion re-points closed views: deleteProviderProfile now 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).
Activation writes from the stored record (read-back feeds every post-save consumer; CR Security Boundaries).
Clear/re-point cache rollback on durable write 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.
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. One deliberate adaptation: upstream opts upsertProviderProfile into runToCompletion; 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 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. 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.
…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).
…-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).
…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).
Editor tabs now have dedicated New Task, Settings, Marketplace, and History actions.
Mode and provider-profile selections are saved separately for each view and restored when it reopens.
Changes to a provider profile are reflected in views using it; deleting a profile selects a surviving option when available.
Tab actions and input focus target the relevant editor tab when one is active.
Bug Fixes
Improved recovery when saved profile selections are missing or invalid.
Renaming a profile updates views that use it and rejects names already in use.
Browser fallback state is retained when local storage is unavailable or a write fails.
Importing or exporting settings no longer overwrites or includes view-specific selections.
Failed settings writes no longer overwrite newer values.
Profile deletion errors distinguish deletion failures from failures to activate a replacement profile.
The changes add persisted per-view mode and profile selections, coordinate profile mutations across live views, and add tab-specific editor commands. They also update launch-state handling, settings import and export, and related tests.
Changes: Per-view state and configuration
Layer / File(s)
Summary
View identity and persistence packages/types/src/*, webview-ui/src/utils/vscode.ts, webview-ui/src/context/ExtensionStateContext.tsx, src/core/webview/ClineProvider.ts, src/core/config/ContextProxy.ts, src/core/config/importExport.ts
The settings schema adds persisted viewStates. The webview creates and sends a view ID. ClineProvider registers IDs and loads and saves view-local selections. Import and export omit viewStates, and failed global-state writes restore the cache unless a newer write exists.
View-local state and mode operations src/core/webview/ClineProvider.ts, src/core/webview/webviewMessageHandler.ts, webview-ui/src/context/*
Returned state overlays view-local values on shared state. Mode changes compensate writes on failure or cancellation. Launch handling validates view-local profiles, and generic updates skip host-owned settings.
Profile lifecycle and message handling src/core/config/ProviderSettingsManager.ts, src/core/webview/ClineProvider.ts, src/core/webview/profileDeletionError.ts, src/core/webview/webviewMessageHandler.ts
Typed not-found errors identify missing profiles. Profile operations synchronize affected views and compensate writes. Message handling delegates deletion and rename operations through the provider and distinguishes replacement-activation failures.
Tab command registration and panel lifecycle packages/types/src/vscode.ts, src/package.json, src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts
Tab-specific editor-title commands route to the provider for the tracked panel. Overlapping panel opens share a creation promise, and failed setup attempts provider and panel cleanup.

Merge Risk: Moderate · up to 45f81
Resolve the remaining state-consistency issues before merging: mode changes can be hidden by existing pins, failed profile operations can leave views on inconsistent settings, and concurrent reset operations can retain or restore cleared selections. Profile-list lookup failures also bypass deletion error reporting.
Security Architecture Review
Security architecture risk:🟡 Moderate · up to b4057
Owner-specific command routing improves isolation between views. However, profile deletion can propagate a replacement profile name without matching configuration after a lookup failure. This could leave subsequent work using an unintended account or endpoint. Failure and recovery coverage remains incomplete.
Retained concerns
Medium · security · inferred: The new multi-view deletion transition publishes replacement profile names even when replacement configuration lookup fails. Configuration replacement is conditional, but durable re-pinning continues, leaving affected views capable of serving the deleted profile’s cached configuration under another profile’s name. This extends a pre-existing shared-selection inconsistency into other live views and their persisted selections.
Security review details
Security Blast Radius
inferred — The identified consistency exposure extends to live provider views sharing the profile and settings store, including views other than the deletion initiator. Its sensitive consequence is subsequent work inheriting unintended provider configuration; broader tenant, service, environment, or IAM exposure has not been established.
Security Findings and Attack Paths
inferred — If the public deletion transition runs and replacement lookup fails, it can persist the replacement name while retaining the removed profile’s configuration overlay. Later task creation can consume that configuration. This supports a conditional account or endpoint misselection risk, not verified exfiltration or an unauthenticated attack path; production caller reachability remains unresolved.
Trust Boundaries and Controls
observed — Client-supplied persistence IDs are normalized and reject proto; restoration checks that persisted modes still resolve. These are storage-key and semantic-validation controls, not demonstrated authentication controls. Tab command ownership uses actual panel identity rather than the client-supplied persistence ID.
Resilience and Maintainability Implications
observed — Tracked-tab handlers stop when no owning provider resolves. Concurrent tab creation shares a pending operation, and disposal clears the tracked panel only when identities match, containing ordinary duplicate-creation and stale-cleanup failures.
Hardening Proposals
proposed — Resolve and validate replacement configuration before committing deletion, and reconcile selected identity and effective settings together across affected views. If reconciliation fails, prevent affected views from starting new work until a matching configuration is established.
proposed — For the residual mode-cancellation limitation, define a terminal cancellation contract covering every durable write and late completion. Validate compensation and ordering when cancellation occurs during shared or per-view persistence, rather than treating pre-write checks as complete cancellation protection.

Explanation
The description covers the change scope, implementation details, review focus, test procedure, verification results, checklist, and documentation impact. It references tracking issue #1992, but it does not provide the template's requested Get in Touch section and does not use a standard Closes issue line because this is a split unit.
Full details: Security Boundaries
Explanation
The previous security finding remains. webviewDidLaunch passes webview-controlled message.viewStateId to setViewStateId (src/core/webview/webviewMessageHandler.ts:603-615). setViewStateId rejects malformed IDs and IDs held by live providers, but it does not verify durable ownership (src/core/webview/ClineProvider.ts:873-931). dispose() removes the provider from activeInstances while retaining its durable viewStates entry (src/core/webview/ClineProvider.ts:1453-1460, 3452-3454). A compromised webview that knows a closed view's ID can therefore adopt it. loadViewState resolves the persisted profile through ProviderSettingsManager.getProfile and places the returned profile settings into local state (src/core/webview/ClineProvider.ts:948-988). getState then includes that configuration in the state posted to the webview (src/core/webview/ClineProvider.ts:4628-4632, 5211-5221). This can disclose stored profile credentials. The added test covers only collision with another live view and does not cover adoption after disposal.
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 webviewDidLaunch on another provider, and verifies that profile settings and credentials are not loaded or posted.
Full details: Persistence Integrity
Explanation
The prior persistence defect remains in the changed deletion path. deleteProviderProfileUnlocked calls rePinViewLocalStateForDeletedProfile at src/core/webview/ClineProvider.ts:3499. That method awaits persistStickyProviderProfileToCurrentTask at :4148, but the helper catches and logs all updateTaskHistory failures at :3778-3805. updateTaskHistory awaits the durable task-history store write at :5353-5360. If that write fails after the view pin is persisted, deletion still completes while the task remains durable history-pinned to the deleted profile.
Resolution
Use a strict persistence mode or a dedicated deletion re-pin helper that propagates task-history failures. Snapshot each affected task and history item before re-pinning. If any history write fails, reject deletion so compensation runs. Restore each task's prior apiConfigName and history item with independent awaited attempts, and surface any restore failure as an explicit inconsistent-state error. Do not report deletion success while task history names the deleted profile.
Full details: Regression Evidence
Explanation
The prior regression remains unresolved. src/package.json changes the visible editor/title menu for activeWebviewPanelId == zoo-code.TabPanelProvider to four new tab commands: plusButtonClickedInTab, settingsButtonClickedInTab, marketplaceButtonClickedInTab, and historyButtonClickedInTab. The PR changes no apps/vscode-e2e file or snapshot. The existing Playwright visual test captures only the sidebar and selected webview frames (apps/vscode-e2e/src/visual/electron.visual.ts:250-266), and its scene controller supports only welcome and chat (apps/vscode-e2e/src/visual/sceneController.ts:51-65). Unit routing tests do not capture the editor 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 routing unit tests.
Full details: Lifecycle Resource Cleanup
Explanation
The tab creation path can leak resources when ClineProvider construction throws. createTabPanelUnlocked constructs ClineProvider at src/activate/registerCommands.ts:397-404, but its cleanup try starts at line 408. The constructor adds the instance to activeInstances at src/core/webview/ClineProvider.ts:472 and creates WorkspaceTracker at line 495. WorkspaceTracker registers file and tab listeners at src/integrations/workspace/WorkspaceTracker.ts:41-73 and owns debounce timers at lines 94-134. If watcher or listener registration, or later constructor initialization, throws, no provider is returned to disposeFailedTabCreation. The pending creation slot is then cleared at registerCommands.ts:304-317, so a retry can create duplicate lifecycle resources while the failed instance remains registered.
Resolution
Make ClineProvider construction exception-safe. Guard the constructor or use a factory that tracks partial initialization, disposes WorkspaceTracker, timers, listeners, tasks, and other resources, and removes the instance from activeInstances when construction fails. Keep tab and panel cleanup safe, then rethrow the original error so a retry cannot duplicate lifecycle work.

…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.

The rename compensation still stops early when the reverse re-point fails.
In both compensation blocks, deleteConfig(newName) runs inside the same try as the reverse repointViewLocalStateAfterProfileRename(newName, oldName, previousRecord). If the reverse re-point rejects, the new record is never removed. Both names then stay stored with the same id. The only trace is the log line, and the user sees the generic rename error.
Run each restore step in its own try, collect the failures, and report an incomplete compensation as a distinct inconsistent-state error. Add a regression test in which the reverse re-point rejects, and assert that deleteConfig("new-profile") still runs.
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.

…s out of compensation
Two review threads on Zoo-Code-Org#1919:
- The scoped compensation replayed the whole pre-deletion viewStates snapshot, dropping sibling writes that queued on persistedViewStateWriteQueue while the deletion waited. It now re-reads the durable map and rewrites only the entries the deletion re-pointed (same merge pattern as the outer compensation), skipping the write when nothing changed.
- The two post-commit postStateToWebview() calls were bare awaits, so a posting failure entered the outer catch AFTER the deletion committed and ran the compensation against a durable deletion. They now go through postStateToWebviewAfterCommittedDeletion(), which logs and continues.
Also closes the unit-local compensation gap the Persistence Integrity check names: before the survivor is persisted into live tasks, the re-pin snapshots each instance's task apiConfigName + task-history item, and the scoped compensation restores them together with the view pins.
Test: "keeps a committed deletion when posting the committed state fails" (postStateToWebview rejects; the profile stays deleted, listApiConfigMeta stays pruned, failure is logged, no throw). ClineProvider + sticky-profile suites 364 passed; eslint/tsc clean.
Security Boundaries — provenance and disposition (fix lands in the owner units)
The remaining error is real at this head but inherited: the vulnerable path is replayed from the base series, not authored here.
Evidence:
main @ 05d01f33d has no setViewStateId at all (git grep setViewStateId upstream/main is empty), and the PR diff contains + await provider.setViewStateId(message.viewStateId) — so it is inside this PR's delta, but replayed.
Tracked as #2151: bind each durable view-states entry to a host-minted claim token (never chosen by webview input), reject unbound/mismatched ids before loadViewState/re-keying, and add the dispose-then-adopt regression test that fails today.
Sequencing: the claim binding lands in #1546 (store/enforcement) and #1552 (launch protocol); the replayed units inherit it via refresh, which also lets their 1200+-line inherited deltas collapse back toward their declared unit. Fixing it here instead would collide with six sibling branches, so this PR keeps only its own two fixes plus the compensation-gap closure.
Keep the F2a guarded teardown (attemptCleanup) and view-state statics; drop the removed private disposables field/loop, matching the earlier unit-chain resolution.

Restore shared writes when a ContextProxy write rejects.
ClineProvider.setValues awaits this.contextProxy.setValues(sanitizedValues) before its try block. If one key write rejects, the sibling writes that Promise.all already started still persist, and the restore never runs. createTask then throws, but the shared settings keep the partial configuration. The rejection path already exists on the merge base and this PR does not change it. Fixing it needs rollback in ContextProxy.setValues or a wider wrapper, so treat it as a follow-up.

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.
Rebuilt the spec from upstream/main and re-applied the branch additions (vscode viewStateId launch mock and the view-local mode/profile test); 43 tests pass.

Bump the write generations in resetAllState.

Bump the write generations in resetAllState.
A global-state write that is still pending when resetAllState runs can restore its pre-reset value after it rejects. Reset does not advance stateWriteGenerations, so the rollback in updateGlobalState still matches. getGlobalState then returns a value that reset cleared from storage. Invalidate the pending writes for every key during reset.
Suggested fix
public async resetAllState() {
// Clear in-memory caches
this.stateCache = {}
this.secretCache = {}
+ // Invalidate pending writes so their rejections cannot restore pre-reset values.+ for (const key of GLOBAL_STATE_KEYS) {+ this.stateWriteGenerations.set(key, (this.stateWriteGenerations.get(key) ?? 0) + 1)+ }

Update resetAllState to increment the generation in stateWriteGenerations for
every key in GLOBAL_STATE_KEYS, invalidating pending writes so updateGlobalState
cannot restore pre-reset values after a rejection.
Add a cold-start rejected-write test for apiProvider.
124-130: Minor · Functional Correctness · Quick win
Add a cold-start rejected-write test for apiProvider.
The rollback test at src/core/config/__tests__/ContextProxy.spec.ts:123-131 seeds "anthropic" before the rejected write. The restore therefore runs with a defined previous value. The repository's test guidelines for src/core/config/** require false/unset coverage, and for fallback behavior they require both the cold-start case (no prior state) and the warm case (prior state exists). This file covers only the warm case for the rollback path.
A regression that skips the restore when the previous value is undefined would leave "openrouter" cached for the unset key. The existing test would still pass. The suggested test covers that case by rejecting the first write to an unset key and asserting that getGlobalState returns undefined.
Suggested test
+ it("should clear the cache when the first write to an unset key rejects", async () => {+ mockGlobalState.update.mockRejectedValueOnce(new Error("write failed"))++ await expect(proxy.updateGlobalState("apiProvider", "openrouter")).rejects.toThrow("write failed")++ expect(proxy.getGlobalState("apiProvider")).toBeUndefined()+ })

Add a cold-start rejected-write test alongside the existing rollback test for
`updateGlobalState`: reject the first write to an unset `apiProvider` key and
assert that `getGlobalState` returns `undefined` afterward.
Rollback after a rejected write can leave an unpersisted cached value.
383-383: Minor · Data Integrity & Integration · Heavy lift
Rollback after a rejected write can leave an unpersisted cached value.
updateGlobalState saves the cached value that is present before each write. When that write rejects and still owns the key, it restores the saved value. If an earlier write to the same key is still pending, the saved value is that pending write's value, and storage has not accepted it. When both writes reject, getGlobalState can return that value. It stays until a later write or a reload replaces it.
Possible approach
Track the last value that storage accepted for each key. On rejection, restore that value instead of the value cached before the failed write.

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.

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.

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

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.
