Related GitHub Issue

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.ts 283 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.

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:

1. 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.
2. 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.
3. 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").
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. Deletion compensation vs other provider instances (Major) - addressed: same merge-style restore as row 3, with a one-to-one negative control.

Verification numbers (head 8a43f2b)

• ClineProvider.spec 316/316 (2 new tests: rebuild on active-profile deletion; no rebuild when not active)
• webviewMessageHandler.spec 91/91, ClineProvider.sticky-profile.spec 18/18, ProviderSettingsManager.spec 55/55
• Negative control: removing the new deletion-completion block reddens exactly the rebuild test (1 failed / 315 passed); restore byte-exact (hash match)
• tsc 0 errors; eslint --max-warnings=0 clean on both touched files; suppression counts unchanged
• Prettier merge-ref gate ALL-MATCHED

Post-commit activation error distinction (head 91dfd64)

• 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.

Pre-merge ERROR-row pre-check (head d5c69d3)

• 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)

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:

1. 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.
2. 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.
• Verified: ClineProvider.spec 323 green, sticky-mode 33 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

---

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).
• Verified: ClineProvider.spec 324 green, sticky-mode 33 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

Stryker suppression comments removed

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).

Row-9 update (head 0dae49a)

• 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.

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 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.

Summary

Summary by CodeRabbit

• New Features
  • 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.
  • Profile changes are reflected in views using that profile; 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 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 replacement-activation failures.

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.

Merge Risk: Moderate · previous review 4dcc3

Profile saves, deletions, renames, and resets can leave view selections, stored settings, and running tasks inconsistent after failures or concurrent actions. Resolve these state-consistency risks before merging, or explicitly accept the affected recovery behavior.

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.

Full details: Security Boundaries

Explanation

The prior security finding remains unresolved. The changed path accepts a renderer-supplied message.viewStateId in webviewMessageHandler.ts:604-616; ClineProvider.setViewStateId only validates syntax and collisions with currently live providers (src/core/webview/ClineProvider.ts:954-1012). dispose() removes the provider from activeInstances but does not remove its durable viewStates entry (src/core/webview/ClineProvider.ts:1538-1551). Therefore, after the original view is disposed, a crafted or compromised webview that knows its stable ID can submit that ID, load the persisted profile through loadViewState and ProviderSettingsManager.getProfile (src/core/webview/ClineProvider.ts:1029-1068), and receive the profile configuration through getState and launch state posting (src/core/webview/ClineProvider.ts:5444-5533). The persisted schema has no owner binding (packages/types/src/global-settings.ts:118-134). The added regression test covers only collision with another live view (src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts:1916-1947).

Resolution

Bind each stable view-state ID to its owning extension-host webview, or use a host-minted capability that the renderer 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, submits its known ID through webviewDidLaunch on another provider, and verifies that profile settings and credentials are not loaded or posted.

Full details: Persistence Integrity

Explanation

The deletion path can still report success while task history keeps the deleted profile. The changed deleteProviderProfileUnlocked path awaits rePinViewLocalStateForDeletedProfile (src/core/webview/ClineProvider.ts:3736-3779). That helper calls persistStickyProviderProfileToCurrentTask (:4431-4437), which awaits updateTaskHistory, but catches and logs every failure (:4064-4081). updateTaskHistory awaits the durable TaskHistoryStore.upsert (:5666-5680), so a failed task-history write is possible. If a sibling task is pinned to the deleted profile and this write fails, the helper resolves, deletion remains committed, and durable history still names the deleted profile. The existing deletion compensation does not run because it only runs when the helper rejects.

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: Description check

Explanation

The description provides detailed scope, implementation context, testing steps, verification results, and checklist coverage. However, the required Related GitHub Issue field does not contain an approved issue in the prescribed format and explicitly states that no approved issue is linked.

Resolution

Add the approved tracking issue in the Related GitHub Issue section, using the required format such as Closes: #1992 if that issue is approved for this PR. Complete the required Get in Touch field and keep the checklist consistent with the actual issue-link status.

Full details: Regression Evidence

Explanation

The prior regression remains unresolved. src/package.json changes the visible editor/title actions for activeWebviewPanelId == zoo-code.TabPanelProvider to four new tab-specific commands: New Task, Settings, Marketplace, and History. This is a durable visible UI change. The pull request adds no Playwright visual test or baseline snapshot. The existing apps/vscode-e2e/src/visual/electron.visual.ts tests only welcome and chat, focuses zoo-code.SidebarProvider, and captures sidebar screenshots plus one webview screenshot. The screenshot directory contains no editor-tab title-bar snapshot.

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 constructor-failure leak remains in the changed tab-opening lifecycle. createTabPanelUnlocked constructs new ClineProvider at src/activate/registerCommands.ts:405-412, but the cleanup try starts only at line 416. If synchronous constructor initialization fails after registration, disposeFailedTabCreation cannot run. The constructor adds the provider to ClineProvider.activeInstances at src/core/webview/ClineProvider.ts:536 and creates WorkspaceTracker at line 562. WorkspaceTracker owns file/tab listeners and debounce timers. A constructor failure after those steps leaves the provider and resources registered. The in-flight promise then clears, so a retry can duplicate the lifecycle work.

Resolution

Make ClineProvider construction exception-safe. Guard construction with a factory or partial-initialization cleanup that removes the provider from activeInstances and disposes WorkspaceTracker, timers, listeners, tasks, managers, and other initialized resources. Keep panel cleanup independent, then rethrow the original constructor error so retries cannot duplicate resources.

Add a two-provider launch-routing test.

The current launch tests invoke webviewMessageHandler with one mock provider at a time. The two-provider tests call setViewStateId and saveViewState directly, so they do not verify that separate webview messages reach the correct provider and restore distinct persisted selections. Add a host-side test that sends different webviewDidLaunch IDs through two provider message listeners and asserts each provider's restored selection.

Bump the write generations in resetAllState.

51-51: Minor · Data Integrity & Integration · Quick win

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.

Learning: Persistence integrity: Fail only when a concrete changed persistence path can lose or corrupt state because an operation is not awaited, a write is non-atomic, rollback or explicit partial-failure behavior is missing, or a persisted default is not propagated to a consumer. Cite the changed path and a plausible triggering scenario; pass when no such changed path exists.

Apply the mapped profile when a mode switch times out after commit.

2850-2853: 🎯 Functional Correctness | 🟡 Minor | 🏗️ Heavy lift

Apply the mapped profile when a mode switch times out after commit.

After ModeChanged fires, the signal?.aborted checks at lines 2914 and 2920 return before getModeConfigId, listConfig, and profile activation run. A timeout in that window leaves the new mode persisted while the task keeps the previous profile. Complete the profile activation after the commit, or roll back the mode before returning. This defect predates the change.

Update the mode-switch flow around `TaskModeSwitched` so an abort after the mode
is committed cannot leave the task using its previous profile: complete the
mapped-profile activation before returning, or roll back the committed mode
first. Preserve the existing timeout behavior and ensure `getModeConfigId`,
`listConfig`, and profile activation are not skipped while the new mode remains
persisted.

Restore the profile manager record when a read before the compensation block fails.

4074-4077: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚖️ Poor tradeoff

Restore the profile manager record when a read before the compensation block fails.

Activation rewrites the profile manager's current profile at line 4066, before the getState() read at line 4076 and the compensation try block. If that read fails, the manager keeps the new name while shared selection keeps the old one. A later settings import with no valid profiles then adopts the stale name (importExport.ts:210, 244). Restore the manager record on this path.

Check the upsert result before sending the credentials-ready message.

4595-4598: 🎯 Functional Correctness | 🟡 Minor | ⚖️ Poor tradeoff

Check the upsert result before sending the credentials-ready message.

When a backup Zoo Gateway profile save fails, upsertProviderProfile returns undefined, and the loop ignores it. The credentials-ready message is then sent anyway, while the failed profile keeps its old zooSessionToken. This predates the change. The PR narrows it, because the loop now continues to later profiles instead of stopping at the first failure.

Restore a command-level test for the createDiagnosticsReport providers argument.

134-134: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Restore a command-level test for the createDiagnosticsReport providers argument.

This PR deletes the only test that runs zoo-code.createDiagnosticsReport and checks the providers array it receives. The handler still passes ClineProvider.getAllInstances(), so current behavior is correct. Nothing in the suite now detects a later change that passes only the sidebar provider or an empty array.

Restore a test that invokes the command handler, mocks ClineProvider.getAllInstances to return both sidebar and tab instances, and asserts that createDiagnosticsReport receives the full array.

Assert the tab New Task message order.

647-651: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Assert the tab New Task message order.

plusButtonClickedInTab posts chatButtonClicked and then focusInput (src/activate/registerCommands.ts:163-164). The tab test checks each message with a separate toHaveBeenCalledWith call, so the test still passes if the two posts are reversed. The sidebar path documents the same order as intended (src/activate/registerCommands.ts:148-151), so this order is the behavior the test should protect.

Reversed order can leave focus off the chat input. focusInput runs before the chat view is shown. The textarea focus call does not check isHidden (webview-ui/src/components/chat/ChatView.tsx:920-921). The later chatButtonClicked shows the view, and the visibility effect focuses the textarea only when the view is visible and the document has focus (webview-ui/src/components/chat/ChatView.tsx:1121-1126). Focus after the reversed order therefore depends on the document focus state.

Assert the exact call sequence. The mock in this test receives only these two posts, so the full-array check is safe.

Validate the mode slug before the durable mode write.

2812-2812: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Validate the mode slug before the durable mode write.

handleModeSwitchUnlocked persists the slug without a getModeBySlug check, unlike setValues. A new task then filters its tools with isToolAllowedForMode, which returns false for an unknown mode. Only always-available tools remain. Reject unknown slugs before the history write and the setValue("mode", …) write.

Narrow the saveViewState key type to the keys it persists.

1183-1187: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Narrow the saveViewState key type to the keys it persists.

saveViewState accepts any key of ViewLocalStateValues, which includes every RooCodeSettings key. The helpers handle only mode, currentApiConfigName, and apiConfiguration. A call with another key, such as alwaysAllowReadOnly, resolves without saving it, and getState keeps returning the old value. No current caller passes another key, so the fix is to narrow the key type.

Suggested fix

-	public async saveViewState<K extends keyof ViewLocalStateValues>(
+	public async saveViewState<K extends "mode" | "currentApiConfigName" | "apiConfiguration">(
 		key: K,
 		value: ViewLocalStateValues[K] | undefined,

Report a committed rename separately from a pre-commit failure.

2608-2608: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Report a committed rename separately from a pre-commit failure.

When activateProviderProfile({ name: newName }) rejects after deleteConfig(oldName) has committed, the outer catch shows only the generic "Failed to rename api configuration" message. oldName stays deleted, and the live views stay pinned to newName. Catch activation errors after the delete commits. Post the webview state and show a message that the rename succeeded but activation failed.

Review comment at @src/core/webview/webviewMessageHandler.ts at line 2608:
Update the rename flow around deleteConfig(oldName) to handle a later
activateProviderProfile({ name: newName }) failure separately from failures
before the deletion commits. After activation fails, post the updated webview
state and report that the rename succeeded but activation failed; preserve the
existing failure handling for pre-commit errors.

Activation failure leaves the shared name and settings mismatched.

696-700: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Activation failure leaves the shared name and settings mismatched.

In the invalid-selection repair, currentApiConfigName is written to the first listed profile before activateProviderProfile runs. If activation rejects, the name stays set and the settings do not match it. Later launches see a valid name, so the repair does not run again. Write the selection only after activation succeeds, or skip the early write when a profile name exists and let activation persist the selection.

Suggested direction

Do not write currentApiConfigName before activateProviderProfile when name is set. Activation persists the selection through setValue. Keep the updateGlobalState call only for the empty-list case, where it clears the invalid name.

Add a bound to the profile storage wait in a follow-up.

443-448: 🩺 Stability & Availability | 🟡 Minor | ⚖️ Poor tradeoff

Add a bound to the profile storage wait in a follow-up.

The queue now chains to run, so a secrets.store call that never settles keeps every later profile mutation pending. The abort signal does not reach that call. ProviderSettingsManager.lock already blocks later operations at the same storage call, so this wait predates the hunk. Track it as a follow-up.

Compensate or complete the mode switch after ModeChanged emits.

2943-2943: 🎯 Functional Correctness | 🟡 Minor | 🏗️ Heavy lift

Compensate or complete the mode switch after ModeChanged emits.

After the durable mode write and ModeChanged emit, handleModeSwitchUnlocked awaits getModeConfigId and listConfig. A stall there that passes the 30-second timeout rejects the caller with "Provider profile mutation timed out". The new mode stays persisted, and the mode's profile is not activated. The handler code (webviewMessageHandler.ts:2211) does not reconcile this state.

This window exists in the base revision. The PR does not introduce it.

Suggested direction

Choose one: run the post-emit profile lookup and activation to completion (for example, through runToCompletion), or roll back the mode when a post-emit abort occurs. The fix needs a design decision, so this comment does not include a diff.
