fix(webview): invalidate live sibling view state on reset and settings import (vps2 F4) - #1562
Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1561 (this series' gap record; the original upstream bug is #980). Port source: upstream PR #981 (fix(webview): invalidate per-view state after reset and import) — closed draft, superseded by the vps2 series; the fork issue 41 ledger names #981 as the F4 port source.
src/core/webview/ClineProvider.ts — broadcastResetToAllInstances(): every live instance clears its in-memory view-local state (_clearViewLocalState), the single global viewStates clear removes the durable per-view entries in one write-queue clear, and each non-calling instance re-posts its state to its webview. Wired into resetState before its final postStateToWebview(). This round also: the F1a view-identity review fixes are ported into this unit's copy (temporary-id authorship flag, ownsTargetEntry re-key gate, null-prototype viewStates, loadViewState ownership guard, setValue/setValues rollback).
src/core/config/importExport.ts — ImportWithProviderOptions gains the optional broadcastResetToAllInstances(); importSettingsWithFeedback broadcasts after the settingsImportedAt write behind a try/catch (a broadcast failure is console.warn'd and never fails the import).
src/core/config/tests/importExport.spec.ts — the 3 ported tests (broadcast on success; skip when the callback is missing with a console.warn negative assertion; import stays successful when the broadcast throws).
src/core/webview/tests/ClineProvider.parallelMode.spec.ts — the F4 multi-instance + _clearViewLocalState describes (CS-verbatim); this round every construction passes the shared WebviewFocusTracker.
src/core/webview/tests/ClineProvider.spec.ts — the F3 resetState sentinel forward fix (viewStates key removed, toBeUndefined) plus this round's ported sticky-mode persisted-view-state-keys suite, rollback tests, and re-key ownership adaptations.
src/extension/tests/api-set-configuration.spec.ts — passes the required ClineProviderFactory argument (main's new constructor parameter).
Upstream main 793b65b merged (this round): 5 conflicts reconciled both-sides — openClineInNewTab keeps the serialized flow on main's typed options + shared tracker; getState keeps the per-view mergedStateValues reads including main's new alwaysDenyUnapprovedCommands; the non-await postMessage path keeps the original-content strip.
Budget
Unit delta vs the stack base: 5 files, +342/-1 — well under the 400-soft budget. The PR diff vs upstream/main is larger because the branch is stacked on the unmerged F1-F2 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.
vitest: ClineProvider.spec + sticky-mode + registerCommands + parallelMode + api-set-configuration 404/407 (the 3 failures are local-only: the donor-built @roo-code/types dist predates alwaysDenyUnapprovedCommands, so globalSettingsSchema strips it locally; CI builds types from source); webview-ui ExtensionStateContext 25/25; packages/types global-settings 9/9.
eslint --max-warnings=0 clean on all touched files; eslint-suppressions ClineProvider.spec.ts 196 -> 194 (decrease), no count increased.
Negative control: forcing the re-key ownership check to true reddens sticky-mode "does not merge a stale temporary-id entry"; restored byte-exact (sha256 match).
Prettier: full-repo check passes on the PR merge tree (merge ref 52a8a93).
Ported the F1a view-identity review fixes into this unit's ClineProvider copy; adapted the re-key tests to author entries through the real write path; ported the sticky-mode persisted-view-state-keys suite, rollback tests and the viewStates global-setting tests.
Added the required WebviewFocusTracker constructor argument to the 84 ClineProvider.spec and 44 parallelMode.spec constructions; api-set-configuration.spec passes the required ClineProviderFactory.
Unit-delta local Stryker preflight was certified at the pre-merge head; the stacked CI mutation-diff reports a changed-line cap artifact by construction (inherited shared content).
Series mechanics
PR base is main; the branch is stacked on the F2 head; merge order F1a -> F1b -> F1c -> F2 -> F3 -> F4 -> F5 -> F6 -> F7.
CS not-ported register (for consistency): kimi-code OAuth try/catch + routerModels.spec +29; ApiConfigManager min-w-0->grow; ApiConfigManager.visual.tsx deletion + 2 PNG baselines; mojibake comment; providers/, .coderabbit.yaml, .github/, CONTRIBUTING.md, .gitignore churn — none of these touch the files in this PR.
Security Boundaries / view-state id rows: addressed at 7e649e9. 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.
Proofs at 7e649e9: sticky-mode 33/33; 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 73c0b90: 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 59744fd)
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 4b28d3d)
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 db6299d)
A review round on the mode-profile-writes unit found fixes this unit carries. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
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.
Proofs: ClineProvider.spec 287/287, sticky-mode 34/34 (new pin-write-failure rollback test), parallel-mode 37/37 (sibling re-pin test asserts the task handler rebuild and sticky-name re-point); negative controls: dropping the rollback call reddens exactly the rollback test, dropping the rebuild reddens exactly the re-pin 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.
Updated this round (CodeRabbit follow-up, head 574dfeb)
Mode-switch atomicity: handleModeSwitchUnlocked now reconciles every write it owns (shared mode, durable view pin, task mode, task history) when a failure lands after the task-mode write - including the mode-linked profile activation - so submitUserMessage delivers the submitted message on the pre-switch mode and profile instead of a half-applied switch. Regression test fails the activation after the task-mode write and asserts all four stores are restored (negative control: reverting the reconcile reddens exactly that test).
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 guarded by taskApiConfigName); regression tests cover both sites.
Test hygiene: prune assertions compare full kept entries; the two re-key storage tests seed through the durable write path so their assertions can fail; sticky-mode afterEach disposes the per-test provider before resetting the instance registry; the webview state-payload test renamed to describe what it asserts.
Updated this round (CodeRabbit follow-up 2, head 1849e73)
Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite 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); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.
Updated this round (CodeRabbit follow-up 3, head c40a67a)
Mode-switch reconcile (this unit's thread): the rollback is skipped once the mode-linked activation has started writing shared state - a mode-only rollback would pair the old mode with the profile the activation switched to - and also when the mutation signal has aborted (the queue has advanced; a newer mutation may own the mode stores). The trailing state post now runs outside the reconciled region: a UI-refresh failure after a committed switch is logged, not rolled back. Three regression tests included (negative controls: removing either guard or re-throwing the post reddens exactly one test each).
Updated this round (CodeRabbit follow-up 4, head 8fbce54)
Mode-switch events now match the stores: ModeChanged is emitted only after the switch commits (a reconciled failure no longer leaves listeners on the rolled-back mode), and the rollback re-emits TaskModeSwitched with the restored mode for API/IPC consumers. The lock path no longer posts inside the reconciled region (it falls through to the committed-switch tail, where a post failure is logged). The mode-default recording reads the view's effective profile (getValues overlay) instead of the shared slot, so a sibling view's activation cannot become this mode's default. Three regression tests included (negative controls: each mutation reddens exactly its test).
Updated this round (CodeRabbit follow-up 5, head 3c454e5)
The committed-switch guard now flips only when the activation has actually written the activated profile (onSharedWriteStart callback), so a mode-linked activation whose own profile lookup fails (deleted profile) still reconciles the switch. The catch that keeps a switch (activation had written, no abort) now emits ModeChanged and posts state before rethrowing, so listeners and the webview learn the committed mode; the abort branch intentionally stays silent (a newer mutation may own the fields - documented in code). In-try abort checkpoints after the mode writes no longer return silently: they fall through to the emit/post tail so the committed mode reaches listeners and the webview. Three regression tests; negative controls: each mutation reddens exactly its test. The activation-failure test double now mirrors the onSharedWriteStart flip.
Updated this round (CodeRabbit follow-up 6, head 47fc2ff)
Abort-silence rule settled: the emit/post tail announces a switch only while its committed mode is still current (after an abort, the tail checks the effective mode store; a superseded commit stays silent because the newer mutation already announced its own mode). This keeps both invariants: a committed switch is never left un-notified while it is current, and no stale announce clobbers a newer owner. Regression tests cover both branches (still-current -> emitted; superseded -> silent); negative controls: dropping the guard reddens the superseded test, always-silencing reddens the still-current test.
Updated this round (CodeRabbit follow-up 7, head 612c6cc)
The lookup-failure regression test now exercises the REAL activateProviderProfileUnlocked (providerSettingsManager.activateProfile rejects) instead of a stub, so the production placement of the committed-switch flip (only after activateProfile resolves) is covered; a matching test keeps the switch when activateProfile resolves and a later shared write (setModeConfig) rejects. Negative controls: moving the flip above the activateProfile await reddens exactly the rollback test; removing it reddens exactly the kept-switch test.
Updated this round (CodeRabbit follow-up 8, head 1106fcb)
The kept-switch regression test now also pins the task-side state on the committed mode: the task's in-memory mode stays architect and the last task-history write carries mode architect (a trailing rollback of the task-side writes after the committed-switch point would now be caught). Negative control: an extra history write with a different mode in the kept branch reddens exactly this 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: at the catch, this call's own state-change handler only ever re-points the tracked ref at newPanel itself, so tabPanel === newPanel is the only reachable state here; a concurrent re-pointing race is not representable in this spec.
Stryker disable next-line ConditionalExpression: only tool_use and mcp_tool_use entries ever carry an id — the text block pushed in the text case has no id field and the start events reaching this guard always carry the string id locked in by processRawChunk — so the type check cannot change the outcome of entry.id === event.id for any entry this pipeline produces; the false replacement is additionally killed by the rejection tests.
Stryker disable next-line ConditionalExpression: event.name is always a string on this path — the only delta events reaching this handler are emitted by processRawChunk with the tracked start name (never undefined), so the legacy nameless branch below is unreachable defensive code and the conditional always takes the named side.
Stryker disable next-line ConditionalExpression: streamingKey can never be undefined here — makeStreamingKey always returns a string and the legacy lookup branch above is unreachable (see the directive on the event.name check) — so the null side is unreachable defensive code.
Stryker disable next-line ConditionalExpression, EqualityOperator: streamingKey is always a defined string on this path (makeStreamingKey never returns undefined; the legacy branch is unreachable per the directives above), and processStreamingChunk returns a partial ToolUse for a known key, so both defensive conditions reduce to the partialToolUse check and cannot change the observed behavior.
Stryker disable next-line LogicalOperator: event.name is always a string on this path — finalizeRawChunks emits end events with the tracked start name (a string, set before the tracker can start), so the ?? event.id fallback guards a nameless end event this pipeline cannot produce.
Stryker disable next-line ConditionalExpression, LogicalOperator, EqualityOperator: the both-miss case is unreachable via the raw-chunk pipeline — end events carry the locked start name so the compound key resolves the registered entry, and a same-ID rejected-start end is always processed after the accepted start's end has already removed that entry; this defensive path protects against a cross-name end event the pipeline cannot produce.
Stryker disable next-line ConditionalExpression: unreachable defensive region — getStreamingToolCallById can only resolve when the both-miss case above is reachable, which the raw-chunk pipeline cannot produce (see the directive there).
Stryker disable next-line CallExpression,ObjectLiteral: _updateViewLocalStateFromMutation applies only mode, currentApiConfigName, apiConfiguration and provider-settings keys, so a listApiConfigMeta-only payload (deleted call or empty object) is a behavior-preserving no-op.
Stryker disable next-line ConditionalExpression: in this fallback the view does not pin the deleted profile, so when the deleted profile was not the shared selection profileToActivate equals the shared selection itself; forcing the branch only rewrites that same value back into the store.
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 (b)
Ported the payload-customModes fix for setValues mode validation (identical flagged block; regression test added) so the units stay byte-identical at merge.
CR round 2026-10-15 (c)
Ported: the dispose() finally-path deregistration (identical flagged block; regression test added).
The createTask registration-failure rollback now restores the shared mode and the view's own mode pin independently (unset pin stays unset); divergent-pin regression test added. Same fix in all six units carrying the flagged block.
Activation writes from the stored record: upsertProviderProfile reads the saved profile back after saveConfig and feeds the normalized record to every post-save consumer (CR Security Boundaries).
Clear/re-point cache rollback: both durable viewStates writers restore the cache to the durable value when the write rejects, before rethrowing (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. 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.
registerCommands.ts:70 - overlapping openClineInNewTab calls now share one in-flight tab creation (the reuse path still runs first, and the promise is cleared in a finally). Test drives two overlapping calls through the real window and asserts one panel, one ClineProvider construction, and the same provider returned to both. Control: removing the in-flight branch reddens it with expected "vi.fn()" to be called 1 times, but got 2 times.
ClineProvider.ts:3527 - snapshotSiblingOverlaysBeforeSharedSettingsWrite fails the caller's shared write when a sibling pin cannot be read, and draws the same distinction as fix(core/webview): merge view-local state into getState for per-view overrides #1550: a ProviderSettingsNotFoundError (the pin names a deleted profile) is tolerated because this unit's deletion path re-points those views itself (rePinViewLocalStateForDeletedProfile at ClineProvider.ts:3825, repointPersistedViewStates at :835, called from deleteProviderProfile at :3372/:3408/:3469); any other read failure aborts. Pair control: removing the discrimination reddens "should still write the shared store when a sibling pins a deleted profile" (promise rejected ... instead of resolving), and removing the abort reddens "should abort the shared settings write when a sibling's pin cannot be resolved" (promise resolved "undefined" instead of rejecting). fix(webview): invalidate live sibling view state on reset and settings import (vps2 F4) #1562 and fix(core/webview): merge view-local state into getState for per-view overrides #1550 now behave identically here.
Test hygiene (test-only, no production behaviour depends on it): ClineProvider.sticky-profile.spec.ts now disposes the provider it creates in afterEach. It leaked one instance per test into the static registry carrying the profile pin that test had activated; a later test's fresh settings store cannot resolve that pin, so the new abort failed three unrelated tests. Teardown errors are swallowed there because dispose() deregisters in its finally even when that file's CloudService double has no off().
ClineProvider.parallelMode.spec.ts's ProviderSettingsManager double now re-exports the real ProviderSettingsNotFoundError, since the production check is an instanceof and a doubled class would make the tolerated branch unreachable.

New Features
Webview tabs now have distinct commands for creating tasks, opening settings, browsing the marketplace, and viewing history.
Per-view mode and profile selections can be restored when a webview is reopened.
Bug Fixes
Mode changes and profile updates are more reliable across views, including when operations fail or overlap.
Settings imports and configuration updates avoid overwriting local view state and better recover from partial failures.
Opening a new tab reuses available tabs and handles concurrent requests more reliably.
The changes add per-view state identity and update profile, mode, and configuration flows. They also add editor-tab commands with tracked-panel routing, and adjust settings import, tests, and repository maintenance.
Changes: Per-view state and profile coordination
Layer / File(s)
Summary
View identity and state contracts packages/types/src/*, webview-ui/src/utils/vscode.ts, webview-ui/src/context/ExtensionStateContext.tsx, related tests
Global settings and webview messages support per-view state and IDs. The webview wrapper validates, generates, and persists an ID, uses an in-memory fallback for browser state, and sends the ID at launch.
Profile lookup and lifecycle operations src/core/config/ProviderSettingsManager.ts, src/core/webview/webviewMessageHandler.ts, related tests
Provider settings add cross-instance serialization, profile-selection snapshots, and a specific missing-config error. Launch handling validates and repairs selections. Profile save, rename, deletion, and sign-out use provider-level operations with rollback or error handling.
View-local modes and task switching src/core/task/Task.ts, src/core/tools/SwitchModeTool.ts, src/core/webview/webviewMessageHandler.ts, src/core/webview/__tests__/*, related tests
Mode settings reject invalid slugs and use provider methods. Task message submission and the switch-mode tool pass the target task to mode switching. Tests cover view-local persistence, cancellation, failures, and task-state reconciliation.
Configuration writes and rollback src/extension/api.ts, src/extension/__tests__/api-configuration.spec.ts, src/extension/__tests__/api-set-configuration.spec.ts, src/core/config/ContextProxy.ts
Configuration writes filter non-portable settings and save the profile before settings and mode mappings. On failure, the code attempts independent restoration of affected profiles, settings, overlays, and mappings.
Settings import and reset notification src/core/config/importExport.ts, src/core/config/__tests__/importExport.spec.ts
Import skips per-view state. An optional reset broadcast completes before state is posted; broadcast failures are logged and do not fail the import.
Editor-tab command routing
Layer / File(s)
Summary
Tab commands and panel lifecycle packages/types/src/vscode.ts, src/package.json, src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts
Four tab-specific commands route actions to the tracked tab provider. Panel creation can reuse a live panel or share an in-flight creation, and disposal updates the tracked panel reference.
Test and repository maintenance
Layer / File(s)
Summary
Test synchronization and repository updates .gitignore, src/eslint-suppressions.json, src/core/task/Task.ts, src/core/webview/webviewMessageHandler.ts, webview-ui/src/i18n/__tests/TranslationContext.locale-loading.spec.tsx
Ignore patterns and suppression counts change. Locale tests await language loading. Stryker annotations are removed while the guarded code remains unchanged.
Zoo-Code-Org/Zoo-Code#1560: Both PRs change per-view settings isolation, view-local state, and profile/mode coordination.
Zoo-Code-Org/Zoo-Code#2227: This PR uses the durable viewStates pipeline and extends related state restoration and invalidation flows.
Zoo-Code-Org/Zoo-Code#1552: Both PRs cover stable view-state identity, launch handling, and profile re-pinning.
Security Architecture Review
Security architecture risk:🟡 Moderate · up to c9b08
A failed or overlapping reset can leave an open tab using an outdated provider configuration after settings have changed. New tasks can read that configuration, although the observed scope is the local extension’s open views and task creation still checks the organization’s provider allow-list.
Retained concerns
Medium · security · inferred: Reset and import do not consistently invalidate every live view: a rejected durable clear stops the sibling loop, and an in-flight state load can restore a selection read before a successful clear. A stale provider-configuration overlay can then remain authoritative for a subsequent task.
Security review details
Security Blast Radius
inferred — The invalidation boundary covers all live provider instances sharing this extension’s state, rather than an evidenced tenant or remote-service boundary. An affected sibling can retain its local provider overlay until another lifecycle action changes it.
Security Findings and Attack Paths
inferred — Following a user-initiated settings import, a failed clear—or a load that began before invalidation—can leave a sibling’s older API-configuration overlay in place. A later task in that view can consume it. No unauthenticated trigger, allow-list bypass, or cross-tenant exposure was established.
Trust Boundaries and Controls
observed — Import sanitizes shared settings and excludes imported view selections; view-state loading checks that modes resolve and attempts to resolve pinned profiles. New task creation applies an organization provider allow-list check.
Resilience and Maintainability Implications
inferred — Logging and continuing after a broadcast failure preserves the completed import, but leaves no demonstrated retry or recovery step that reconciles sibling buffers with the imported settings.
Hardening Proposals
proposed — Give invalidation a generation marker checked by in-flight loads, and provide a reconciliation path when the durable clear fails, so import success cannot silently leave live views on pre-import provider settings.

Full details: Security Boundaries
Explanation
The prior security issue remains in the changed view-state path. webviewDidLaunch passes renderer-controlled message.viewStateId to setViewStateId (src/core/webview/webviewMessageHandler.ts:596-604). The validation rejects malformed IDs and claims held only by currently live providers (ClineProvider.ts:968-1013). dispose() removes provider A from activeInstances (ClineProvider.ts:1552-1574) but intentionally preserves A's durable viewStates entry, as the changed test asserts (ClineProvider.spec.ts:7266-7282). A replacement or compromised webview can therefore submit A's former ID after A is disposed. loadViewState() then reads the persisted profile name and calls getProfile() (ClineProvider.ts:1049-1097), which returns the complete stored profile (ProviderSettingsManager.ts:489-525). getStateToPostToWebview() sends that configuration in the state message (ClineProvider.ts:4824-4922, 4993-5006), and the message redaction helper does not remove API credentials (stripOriginalContent.ts:72-84). This creates a concrete credential disclosure path to the reassociated webview.
Resolution
Bind each persisted view-state record to an extension-owned panel/webview identity, or require a host-validated unforgeable capability before reassociation. Do not authorize a renderer-supplied ID after its provider is disposed. If secure reassociation is unavailable, clear or retire the durable record during disposal. Add a regression test that disposes provider A, submits A's ID through provider B, and verifies that no credential-bearing apiConfiguration is loaded or posted. Redact credential fields before posting state where possible.
Full details: Persistence Integrity
Explanation
Activation remains non-atomic in the changed path. ClineProvider.ts:3968 persists the manager selection, then :3986-3998 starts list metadata, shared provider settings, current-profile, and view-state-related writes with Promise.all. If the viewStates write rejects, setValue rolls back only currentApiConfigName (:5450-5468). The manager selection, list metadata, provider settings, and any sibling overlay writes can remain committed, leaving persisted stores inconsistent. The changed tests do not cover this post-activation failure.
Resolution
Make activateProviderProfileUnlocked transactional. Snapshot the manager selection/profile, list metadata, shared provider settings, mode mapping, durable and in-memory view state, and sibling overlays before activation. Await all started writes with Promise.allSettled; on failure, compensate every write that landed, restore durable and in-memory view state, and rethrow the original error. Add a direct activation test that rejects the viewStates write after activateProfile and verifies every persistence surface remains unchanged.

Full details: Regression Evidence
Explanation
The standing regression finding remains unresolved. VSCodeAPIWrapper.createViewStateId() now falls back when typeof crypto.randomUUID !== "function" (webview-ui/src/utils/vscode.ts:35-42), but the focused tests cover only a missing member, an undefined crypto, and an inherited non-callable member. No test sets an own randomUUID: undefined property. The malformed-storage test (webview-ui/src/utils/__tests__/vscode.spec.ts:379-400) first expects an undefined fallback, then seeds state after the malformed read, so it does not verify that a pre-existing non-undefined fallback is returned.
Resolution
Add a browser-wrapper test with globalThis.crypto set to { randomUUID: undefined } and assert the deterministic timestamp-random ID. Change the malformed vscodeState test to seed a non-undefined in-memory state before the malformed read, then assert getState() returns that state without throwing and does not re-read stale storage.
Full details: Lifecycle Resource Cleanup
Explanation
The prior lifecycle defect remains. setViewStateId() starts loadViewState() at src/core/webview/ClineProvider.ts:1028; loadViewState() awaits getCustomModes() or getProfile() at lines 1077 and 1089, then checks only whether viewStateId changed. dispose() sets _disposed at line 1559 but does not cancel or invalidate the load. If getProfile() is pending when disposal starts, the unchanged view id passes the guard and line 1181 assigns viewLocalState after disposal. The tests cover superseded ids, but no disposal-during-load case.
Resolution
Add a lifecycle generation or cancellation guard for loadViewState(). Check the guard after each awaited custom-mode or profile read and immediately before assigning viewLocalState. Make setViewStateId() stop or ignore delivery when disposal starts. Add a regression test that defers getProfile(), starts view-state registration, disposes the provider, resolves the profile, and verifies that no state is applied after disposal.

…tore
deleteProviderProfile only rewrote the UI-facing listApiConfigMeta and
currentApiConfigName in ContextProxy, leaving the profile's settings in the
ProviderSettingsManager store (context.secrets). Per-mode mappings
(modeApiConfigs) that still pointed at the deleted profile re-activated its
stale settings on the next handleModeSwitch, clobbering the active
configuration: the subtask child profile's gpt-4.1-mini leaked into
ask-mode tasks, breaking downstream e2e suites (60s timeouts on search_files
no-match and terminal reuse after zero-chunk shell race).
Purge the profile from the store on delete so dangling mode mappings can no
longer resolve it: listConfig().find(id) fails and handleModeSwitch continues
with the current configuration. The F3 mode/profile isolation commit further
up the chain introduces the same purge plus per-view pin handling.
Regression test: sticky-profile spec "deleteProviderProfile removes the
stored profile so a dangling mode mapping can no longer re-activate it".
… state
WMH webviewDidLaunch persists the webview view-state id via provider.setViewStateId and re-pins the view-local currentApiConfigName through provider.saveViewState when the view-local profile is missing but the shared global selection is still valid. updateSettings is routed through provider.setValue so view-local buffer and pin sync stay consistent with the other mutation paths. The webview VSCodeAPIWrapper gains a stable getViewStateId persisted via setState (with an in-memory fallback) and the launch effect posts the id with the webviewDidLaunch message.
…ate ids
getViewStateId now trims and rewrites unsafe characters before reuse, mirroring ClineProvider.setViewStateId, and rejects whitespace-only and __proto__ values by generating a fresh id. Regression coverage: normalized reuse, whitespace-only, and __proto__.
The provider owns a DiagnosticsRequestBroker whose pending entries hold a resolver and a
timeout that close over the provider, and requestWebviewDiagnostics leaves an entry
behind until the webview answers. Nothing disposed the broker, so a view that went away
mid-request kept both alive until the timeout fired - and a teardown that threw on the
way to the last cleanup step would have left them dangling entirely.
Dispose the broker in dispose()'s finally, ahead of the steps that may throw, and pin it
with a test that fails MCP cleanup mid-dispose and asserts both the release and that the
waiting request resolves instead of hanging on its 60s timeout.
Two panel rows point at sibling-unit content — scoping with evidence
The 20:10Z panel re-evaluation on 4770161ce reported 2 ERRORS + 2 WARNINGS. Both WARNING rows are now fixed on this branch — ec2fb372 (mint a view id only through a callablecrypto.randomUUID, plus tests for an inherited non-callable one and for malformed persisted vscodeState JSON) and f555d04a (release the diagnostics request broker in dispose()'s finally, ahead of the steps that may throw, with a regression test that fails MCP cleanup mid-dispose). This comment is only about the two ERROR rows.
At this head the ownership rule is "another live instance already holds this id" (ClineProvider.ts:992-1004). Once the owning provider disposes, the persisted entry becomes adoptable again on purpose — otherwise a key would be bricked for every later view. That is the pre-capability shape of the contract the row describes.
The capability itself — a host-minted claimToken stored with each persisted entry, setViewStateId accepting only a claim the host minted (or minting one itself), refusing renderer-written viewStates, and re-binding claim-less legacy entries — is the content of sibling unit #2226 (vps2/n1-view-identity). Evidence on this branch: git log -S claimToken -- src/core/webview/ClineProvider.ts returns nothing, and git merge-base --is-ancestor shows neither branch head contains the other, so this PR's diff still carries the pre-capability setViewStateId.
#2226 head db5bffa4 now closes the two paths through which a renderer could reach that state: a posted updateSettings is checked against isNonPortableSettingsKey before contextProxy.setValue — the same boundary sanitizeGlobalSettings applies to an imported settings file — and claim delivery reports failure and retries with the stored token instead of dropping it. Implementing the token here too would write the same contract twice, in two branches that both edit setViewStateId, the webviewDidLaunch registration and viewStates, and the two copies would still have to be reconciled at fold-forward. Please assess this row against #2226; whatever remains there belongs to that unit.
2. Persistence Integrity — non-transactional profile activation
Cited: activateProviderProfileUnlocked — the ask is to snapshot the previous manager record and roll back activateProfile, list metadata, the shared selection, provider settings, mode mapping and the per-view pin as one transaction.
This unit's changes inside that function are narrower than the row implies: 312e6885 only tolerates a pin that names a deleted profile while reading the sibling snapshot (hunks at 3586-3606 / 3623-3656), and 4770161 only holds the cross-instance lock around the shared store writes (hunk at 3199, persistProviderProfile). The order in which the six writes are performed, and what is snapshotted before them, is untouched here — that is the profile-switching design carried by #1919/#1921. Making the sequence transactional is a change to that design rather than to the lock this unit adds, so it belongs in the unit that owns the sequence; the same lines are edited there, so a second copy here would conflict on merge.

src/core/webview/ClineProvider.ts:1584-1593 Minor · Stability & Availability · Quick win
Run each teardown step even when an earlier step throws.
dispose() now deregisters the provider in finally. The remaining cleanup still sits in a plain sequence in disposeInternal. A rejection in an earlier step skips every later step, and dispose() cannot run again because _disposed is already set.
Examples:
evictCurrentTask() rejects. view.dispose(), clearWebviewResources(), mcpHub.unregisterClient(), skillsManager.dispose(), customModesManager.dispose() and taskHistoryStore.dispose() never run.
mcpHub.unregisterClient() rejects. skillsManager.dispose(), marketplaceManager.cleanup(), customModesManager.dispose() and taskHistoryStore.dispose() never run.
Result: watchers and the MCP client registration stay alive for a provider that is no longer tracked. The new tests only assert deregistration and broker release. They do not assert that the other steps run.
Run the later steps best-effort and rethrow the first failure at the end. Apply the same helper to the earlier steps in disposeInternal.

Trivial · Complete the providerSettingsManager double so the upsert… · ClineProvider.spec.ts:4992-5000
Complete the providerSettingsManager double so the upsert reaches its success path.
This double has no getProfile. persistProviderProfile calls getProfile after saveConfig to read the record back. The call throws TypeError. The read-back handler then tries to compensate: deleteConfig is also missing, so that step fails and is only logged. The handler then throws. upsertProviderProfile swallows that error.
The ordering assertion at Line 5022 still passes. The upsert fails after saveConfig, and the test cannot detect a regression in the work that follows. Sibling tests in this file already supply a getProfile that returns the saved record.

Failed pre-merge checks:
- Regression Evidence:
Add a focused browser-wrapper test with `crypto: { randomUUID: undefined }` and
assert the timestamp-random fallback ID. Update the malformed `vscodeState` test
so the wrapper first has a non-undefined in-memory state, then storage contains
malformed JSON, and assert `getState()` returns that in-memory state without
throwing.
- Security Boundaries:
Bind each persisted view-state record to an extension-owned webview or panel
identity, or use a host-validated unforgeable capability with secure
reassociation. Do not authorize a renderer-supplied ID after its provider is
disposed. If secure reassociation is unavailable, retire or clear the durable
record on disposal. Add a regression test that disposes provider A, submits A's
ID from provider B, and verifies that no credential-bearing `apiConfiguration`
is loaded or posted. Redact credential fields before posting state where
possible.
- Persistence Integrity:
Make `activateProviderProfileUnlocked` transactional across the manager
selection, profile list, shared selection, provider settings, mode mapping, and
per-view pin. Snapshot the previous manager record and all affected persistence
values before activation. Serialize the writes or await all started writes
before handling failure. If any write fails, restore every write that landed,
including the manager record and provider settings, and restore the in-memory
view buffer. Add a regression test that rejects the per-view `viewStates` write
after activation starts and verifies that the manager record, list metadata,
shared settings, shared selection, mode mapping, and view pin remain on the
previous profile.
- Lifecycle Resource Cleanup:
Add a provider lifecycle generation or cancellation guard to `setViewStateId()`
and `loadViewState()`. Check the guard after every awaited load and before
applying `viewLocalState`; return without applying state when the provider is
disposed or the load is superseded. Add a regression test with a deferred
profile lookup: start registration, dispose the provider, resolve the lookup,
and verify that no stale state is applied. The diagnostics broker cleanup is now
correctly in the unconditional `dispose()` finally block at lines 1509-1515.

The claimed provider-queue deadlock is not present.
The rename callback releases the shared lock before calling activateProviderProfile. Its in-lock repoint helper does not enqueue a provider-profile mutation. persistProviderProfile also holds the shared lock only around saveConfig. The cited cyclic wait and permanent queue blockage are therefore contradicted by the inspected call paths.

No provider-lock deadlock exists in the repoint path.
The repoint operation uses separate view-state and task-history persistence paths. It does not re-enter runExclusiveAcrossInstances or wait on enqueueProviderProfileMutation, so the proposed change is not required.
Carry the activation-ordering fix from Zoo-Code-Org#1557 (8320d78) onto this branch:
the sibling overlay snapshot now runs before activateProfile, so a pin whose
record cannot be read aborts the shared write instead of leaving the store on
the new profile while a mode switch that already passed onSharedWriteStart
keeps the new mode, which would leave mode and provider disagreeing. For an
activation by id the resolved name comes from the manager's own listing, which
the shared write reads as well.
Carried: the ClineProvider change, the apiHandlerRebuild serialization test's
setImmediate flush (the snapshot adds an await before activateProfile), and the
'aborts the shared settings write when a pinned sibling's profile cannot be
snapshotted' regression with its activateProfile spy. That test asserts on the
pin the abort names rather than the sentence, because the sibling branches
phrase this abort differently.
Not carried: the webviewMessageHandler half of 8320d78 and the four
viewStateReadiness tests. They exercise the repair-inside-readiness wiring that
this branch's public setViewStateId does not take; here the launch repair runs
unconditionally after registration, so the skipped-repair behaviour they prove
cannot occur. The re-pin overlay-clearing test is dropped for the same reason:
this branch does not clear a re-pinned sibling's overlay when the replacement's
settings cannot be read - reported to the stack owner rather than silently
changed here.
Verified: ClineProvider.spec 426 passed, apiHandlerRebuild 38 passed,
webviewMessageHandler 143 passed, registerCommands 46 passed, tsc clean,
prettier and eslint clean, src/eslint-suppressions.json unchanged.
createClineTab tracked the panel, then awaited resolveWebviewView with the
panel's listeners registered only afterwards. A rejected initialization left
the failed panel tracked with no dispose listener that could ever clear it,
left the provider bound to that panel and never disposed, and let the next
"Open in editor" click take the reuse path with a provider whose creation had
already failed - the *InTab commands then act on a panel the user had closed.
Register onDidChangeViewState and onDidDispose before the await, and handle the
rejection: only while the tracked panel is still this one, clear the tracked
panel, dispose the panel and its provider, and rethrow the initialization
error. A cleanup failure is logged together with the initialization error
instead of replacing it, and nothing throws out of a finally, so the error that
explains the failure stays the one that propagates.
Tests: "clears the tracked tab and closes the panel when webview resolution
rejects" (tracked panel cleared, panel and provider each disposed once, both
listeners registered before the await, rejection matched by identity) and
"keeps the initialization error when the failed tab's provider teardown
rejects" (expect(thrown).toBe(initError) with the teardown failure logged
beside it).
Controls, each restored byte-identically:
- dropping the catch's cleanup block -> expected { reveal: [Function Mock],
... (5) } to be undefined (the failed panel stays tracked) and the log
assertion fails
- replacing the teardown log with throw disposeError -> expected Error: provider
teardown failed to be Error: webview initialization failed
- moving the two listener registrations back after the await -> expected
"vi.fn()" to be called 1 times, but got 0 times

Resolves the eight open CodeRabbit threads on Zoo-Code-Org#1560 without changing the write ordering those
threads defend:
- webviewMessageHandler: the Zoo Gateway sign-out sweep treats an undefined profile id as a
failed cleanup, because upsertProviderProfile resolves undefined when its write fails instead
of rejecting, so the handler cannot tell a cleared token from a swallowed save.
- registerCommands: openClineInNewTab re-enters the shared tab-panel join when the provider it
awaited turned out to be disposed, instead of opening a second panel beside the replacement.
- ClineProvider: the apiHandlerRebuild specs pin the mode across all three surfaces after a
post-activation shared-write failure, and add a case where provider and model are unchanged
so the handler rebuild is the only thing keeping the task on the new profile.
- ClineProvider: the delete compensation snapshots the sibling overlay before the doomed record
turns unreadable, and reads the selection through saveViewState so the snapshot branch is the
one under test.
- ClineProvider + ProviderSettingsManager: the delete compensation now also restores the
manager gate - its selected profile and every mode mapping - through getSelectionAndModeConfigs
and only while the manager still reports what this deletion wrote, so a concurrent owner is
not overwritten and a mapping this deletion did not move is not replayed.
- api-configuration: the restore-order spec records the write sequence instead of inferring it
from call counts.
The unit-level mutation delta is closed with tests rather than directives or suppressions: a
sign-out scenario in which the tokenless, non-active zoo-gateway profile is left out of the
sweep; the exact clear and failure log lines for an active and a persisted-only profile; a
delete whose activation target is named by the shared selection but absent from the durable
entry list; a concurrent activation that takes ownership of the manager gate between the
replacement activation and the failure; a compensation whose gate read fails outright, proving
the restores behind it are independent; and a delete that starts with the manager already
selecting the profile it goes on to activate.
Local verification: vitest 786 passed across the seven touched specs; tsc --noEmit clean;
prettier --check clean; eslint --max-warnings=0 clean per file with no suppression increase -
webviewMessageHandler.spec.ts drops from 35 to 29 no-explicit-any after the casts are replaced
with typed provider views, and src/eslint-suppressions.json was pruned to match. Fourteen
measured negative controls against this head: mutate, capture the real assertion failure,
restore byte-identically, re-run green - the sign-out skip guard and its body, the undefined-id
confirmation and its message, the three clear-log literals, the optional-chained gate snapshot,
all five manager-gate guard conjuncts, the gate-restore log wording, and the shared-pair restore
ordering.
…ofile-writes
Zoo-Code-Org#2223 landed the time/date format and message-timestamp settings on the same
surface this unit edits, so the branch now carries the merge of main plus this
unit's review fixes in one head. Hand-resolved files:
- src/core/webview/ClineProvider.ts: kept main's displaySettings import and its
three new fields in the state posted to the webview, read from this unit merged
overlay copy so a pinned view posts its own values, and kept this unit validated
setValues while routing its payload through withoutInvalidDisplaySettings so an
invalid display value is dropped and logged before anything is stored, as main
does.
- src/extension/api.ts: kept main SettingsWriteError doc block and its
invalid-display-value filtering, and kept this unit snapshot-then-write,
restore-in-the-same-catch, rethrow-the-original transaction beneath it.
- src/extension/__tests__/api-configuration.spec.ts: kept main new
display-settings tests unchanged in intent, extending their doubles with the
reads this unit performs before its first write and pointing two assertions at
the writes that actually follow the settings here (the mode fan-out and the
webview post) plus the rollback of the record the save already made.
Verified: tsc clean; eslint --max-warnings=0 clean package-wide with no new
suppressions; prettier --check clean; 932 tests across the affected suites green
(api-configuration, displaySettings, ContextProxy, ClineProvider,
webviewMessageHandler, parallelMode, apiHandlerRebuild, registerCommands,
ProviderSettingsManager).
…ps2/f4-cross-instance-reset
Zoo-Code-Org#1560 settled the profile-write plumbing this unit extends, so this head carries
that plumbing plus this unit's cross-instance behaviour, resolved file by file.
Hand-resolved files:
- src/core/webview/ClineProvider.ts: kept main's write machinery - the
previousManagerGate/getSelectionAndModeConfigs snapshot with its id-gated restore,
the hasConfig fail-closed classification of a rejected profile read, the
name-and-id deleteConfig, the launch invalid-pin repair ordering, main's
displaySettings fields read through this unit's merged overlay copy, and main's
settled dispose() cleanup tail with its loadViewState reload - and kept this
unit's cross-instance machinery beside it: the runExclusiveAcrossInstances join
around the store write, the sibling overlay snapshot with its commit-time pin
recheck and its fail-closed refusal to overwrite the shared store, the sibling
postState guards with their named logs, modeSlugResolves, preserveForeignTask,
and the boolean-returning loadViewState delivery seam annotated at both ends.
- src/core/webview/webviewMessageHandler.ts: kept main's launch repair (an
unresolvable view profile re-pins only this view through the durable writes when
the shared selection is still valid) and main's mode-slug validation surface, and
kept this unit's cross-instance section around the profile save and the rename
compensation that depends on it.
- src/core/webview/__tests__/webviewMessageHandler.spec.ts: kept main's launch
tests, which assert that re-pin contract, and retired this unit's two
activation-based variants that the repair replaced; the launch fixture carries
main's activateProviderProfile signature with this unit's activate options.
- src/core/webview/ClineProvider.spec.ts: union of both suites. This unit's rival
double gained the read-back getProfile the writer now performs so the
critical-section ordering test still exercises the save inside the section.
Five of this unit's tests were retired as superseded by main's counterparts: the
two that asserted dispose rejecting on a failing cleanup step (main's tail runs
every later step and reports the failure) and the one that expected an unset
view-profile provider to default to Anthropic rather than follow the shared
selection.
- src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts: the two
registrations of the manager mock now form one double carrying main's gate
(getSelectionAndModeConfigs, hasConfig, gate-backed activation) and this unit's
cross-instance section, exporting the manager's typed not-found class with a
declared fallback because the original-module import can hand back a partially
initialized module for this chain. Main's re-point and replacement-activation
bodies won their titles; this unit's sibling-overlay guard tests stayed; main's
log-and-continue variant was retired as the guard replaces its outcome and the
abort test keeps that coverage; and a deleted profile lookup now rejects with the
manager's own ProviderSettingsNotFoundError, as ProviderSettingsManager.getProfile
does, so a stale pin is not mistaken for a store outage.
- src/activate/registerCommands.ts and its spec: took main's reviewed superset
(the postActions helper, the tab-priority focus panel post, the
all-instances-aware diagnostics handler); this unit's only own content there was
the pre-refactor inline post forms main's helper supersedes, and this unit's
all-instances diagnostics test was ported onto main's handler shape with its
module mock.
- src/extension/api.ts, its configuration spec, and the webview-ui api spec: main's
versions wholesale; the set-configuration spec keeps this unit's five lines beside
main'sseventeen additions.
- src/eslint-suppressions.json: the provider spec's any-suppressions pruned 191 to
188 after the retirements, proved with --prune-suppressions; no count increased.
- .gitignore: main's scratch-file ignore entries.
Verified: tsc clean; eslint --max-warnings=0 clean on every merged path with no new
suppressions; prettier --check clean; 1008 tests across the affected suites green
(api-configuration, api-set-configuration, registerCommands, ContextProxy,
ProviderSettingsManager, ClineProvider, parallelMode, apiHandlerRebuild,
webviewMessageHandler, sticky-mode, sticky-profile, Task.sticky-profile-race).

Review comments at @src/core/webview/__tests__/ClineProvider.spec.ts:
- Around line 6796-6810: Remove the no-op test in the `getState merging` block
that only calls `saveViewState` and `dispose`; it neither exercises `setValues`
nor verifies an outcome. The adjacent test already covers the flat provider
write and overlay removal, so avoid duplicating that coverage.
Review comments at @src/extension/api.ts:
- Around line 722-730: The rollback in setConfiguration replays a stale full
configuration snapshot, potentially overwriting concurrent view-state updates
outside their serialized write queue. Before calling sidebarProvider.setValues
in the rollback, restrict restoreValues to keys present in values, using their
prior values from previousValues; preserve the existing savedProfileName
behavior.
- Around line 649-714: Update setConfiguration to run the profile existence
check and saveConfig within one runExclusiveAcrossInstances section, then
perform rollback restoration or deletion in a separate section using the same
lock. Before rollback deletes the profile, verify the stored record is still the
one this call created, using its saved identifier if available; do not delete a
record that may belong to another writer.
Review comments at

- Around line 752-780: Restore tests around mergeExtensionState for a fresh push
with an empty clineMessages array and no serialized currentTaskId, asserting the
result clears the previous task ID to undefined. Also restore context-level
coverage for internMessages: verify message-string interning and reuse,
messageCache clearing on an explicit task change, and that stale sequenced
updates are not interned.
Review comments at @webview-ui/src/utils/vscode.ts:
- Around line 63-68: Update the validation around normalizedViewStateId to reuse
a stored ID only when it is nonempty and no longer than 64 characters; otherwise
let the existing generated-ID path run. Correct the nearby comment to state that
the host rejects only "__proto__", and add coverage in vscode.spec.ts verifying
that a stored 65-character ID produces a new generated ID.

Failed pre-merge checks:
- Regression Evidence:
Add a browser-wrapper test with `crypto: { randomUUID: undefined }` and assert
the timestamp-random fallback ID. Update the malformed `vscodeState` test to set
a non-undefined in-memory state before the malformed read and assert that
`getState()` returns that state without throwing.
- Security Boundaries:
Bind each persisted view-state record to an extension-owned panel or webview
identity, or use a host-validated unforgeable capability with secure
reassociation. Do not authorize a renderer-supplied ID after its provider is
disposed. If secure reassociation is unavailable, retire or clear the durable
record on disposal. Add a regression test that disposes provider A, submits A's
ID through provider B, and verifies that no credential-bearing
`apiConfiguration` is loaded or posted. Redact credential fields before posting
state where possible.
- Persistence Integrity:
Make `activateProviderProfileUnlocked` transactional across the manager
record/selection, profile metadata, shared provider settings, mode mapping,
shared selection, and per-view pin. Snapshot all prior values before activation,
await every started write, and compensate every write that landed on failure.
Restore the in-memory view buffer as well. Add a regression test that rejects
the per-view `viewStates` write after activation and verifies that all manager,
shared, mode, metadata, and view-pin state remains on the previous profile.
- Lifecycle Resource Cleanup:
Add a lifecycle generation or cancellation guard to `setViewStateId()` and
`loadViewState()`. Check it after each awaited load and immediately before
applying `viewLocalState`; return without applying state when the provider is
disposed or the load is superseded. Avoid starting a new load during disposal
unless it is guarded. Add a regression test with a deferred profile lookup:
start registration, dispose the provider, resolve the lookup, and verify that no
stale state is applied.

No focus-dependent path reaches the sidebar commands after this change.
The four sidebar commands are hidden only from the Command Palette. No keybinding or other menu entry references them. Their view/title entries stay limited to SidebarProvider. The one internal caller, src/extension.ts:107, opens the sidebar on purpose, and its handler targets the registered sidebar provider. The handlers already use that provider, so the proposed routing change to *InTab or getVisibleProviderOrLog is not needed.

5253-5259: Change the unset apiProvider fallback back to Anthropic.
An earlier review comment reported this line, and the author said it was fixed in 152fad9. The current code still has viewApiConfiguration.apiProvider ?? providerSettings.apiProvider.
Suppose a view is pinned to a profile with no apiProvider, and the shared store belongs to another profile. The view then runs that other profile's provider with its own profile fields. The stored-profile default elsewhere is providerIdentifiers.anthropic.
The regression test the author described ("resolves an unset view-profile provider to Anthropic instead of the shared provider") is not in the supplied test files.
3569-3571: Activate the replacement for an unpinned view only when the shared selection named the deleted profile.
An earlier review comment reported this condition, and the author said it was fixed in e6f730a. The current code still activates whenever this.viewLocalState.currentApiConfigName === undefined. That includes deletions of a profile that no view uses.
When this path runs, activateProviderProfile force-rebuilds the current task's API handler and rewrites the shared selection, even for an unrelated deletion. The test "should activate the replacement profile when the deleting view has no profile pin" in ClineProvider.parallelMode.spec.ts (lines 1217-1244) now requires this behavior for an unrelated deletion. Fix the condition and change that test.
1217-1244: Change this test to fail when an unrelated deletion activates a replacement.
This test deletes doomed-profile while the shared selection is keeper-profile and the view has no pin. It then requires activateProviderProfile to be called. The earlier fix (e6f730a) said an unpinned view must not activate a replacement for an unrelated deletion. It also named a test for that rule: "should not activate for an unrelated deletion when the deleting view has no profile pin". That test is not in this file.
The root cause is the viewPinsDeletedProfile condition in ClineProvider.ts (lines 3569-3571), which I reported there. Change this test to expect that activateSpy is not called and that currentApiConfigName stays keeper-profile.
…ites and retake the deleted cases
Resolves the five open CodeRabbit threads on Zoo-Code-Org#1560 at 8cc8f33. Four are teardown in the specs
this unit added; one is a behaviour change confined to the public API round trip.
- extension/api.ts: setConfiguration drops viewStates from the settings payload before the forward
write, and from the snapshot the rollback replays. The map is a snapshot of every view's
selection: writing a caller's copy forward pins views this call does not own, and replaying
the getter's copy on failure rolls them back to where this call found them. Both consult
isNonPortableSettingsKey, the list the export schema above and the import path already use,
which Zoo-Code-Org#2226 adds at its head (e9d0a2a) for the read side of the same round trip - that PR
filters what an external caller may read, this one filters what it may write. getConfiguration
and ContextProxy.getValues keep the key: the host's own consumers still need viewStates.
- core/config/ContextProxy.ts: declares NON_PORTABLE_SETTINGS_KEYS and exports
isNonPortableSettingsKey beside the export schema, so the two PRs share one rule instead of
each keeping its own copy of the key list.
- ClineProvider.spec: the mode-switch timeout test brackets its flow in try/finally so a failed
assertion cannot leave the gate unresolved, the prototype spy installed, or the timers faked
for the rest of the file.
- webviewMessageHandler.spec: the sign-out suite restores the three fixture members its tests
reassign. Measured control: with the assignments unrestored the file is still 176/176, so the
leak is latent rather than failing - vi.clearAllMocks undoes call history, never a property
assignment, and mockClineProvider.contextProxy alone is read 28 times by the eight describes
that follow.
- ClineProvider.sticky-mode.spec: the three temporary-id providers are disposed in finally, and
the third restores mockContext.globalState.update there before disposing, so a failing
assertion cannot leave the rejecting mock installed for the teardown below it.
- webview-ui ExtensionStateContext.spec.tsx: restored the 13 cache-interning and task-identity
cases main carries (from upstream c4ed96c, Zoo-Code-Org#2217) with the expectMessages, InternSpy and
cacheFor scaffolding they need and main's afterEach(vi.restoreAllMocks). They came back with
the merge of main; our scaffolding cleanup (fda1600) removed them without moving them
anywhere, and webview-ui/src/utils/__tests__/stringCache.spec.ts covers the class, not this
provider wiring.
Verified: src tsc --noEmit exit 0; webview-ui tsc --noEmit exit 0; eslint --max-warnings=0 clean
on every touched file with src/eslint-suppressions.json byte-for-byte unchanged; prettier clean.
856 tests green across api-configuration (17), api-set-configuration (1), ContextProxy (64),
ClineProvider (448), sticky-mode (46), sticky-profile (23), apiHandlerRebuild (40),
parallelMode (41) and webviewMessageHandler (176); webview-ui ExtensionStateContext 43/43.
Test (negative control for the API filter): with neither filter in place the new case fails with
`expected { Object (currentApiConfigName, modeApiConfigs, ...) } to not have property
"viewStates"` while the other 16 cases in the file pass.
…ps2/f4-cross-instance-reset
Zoo-Code-Org#1560 settled its review round in one commit: four test-teardown fixes and one behaviour change
confined to the public API round trip. This head takes that settled half and keeps this unit
cross-instance reset machinery intact.
Git auto-merged the four overlapping files and the content was checked hunk by hunk:
- src/extension/api.ts, src/core/config/ContextProxy.ts and
src/extension/__tests__/api-configuration.spec.ts came over from Zoo-Code-Org#1560 unchanged, so the
write-side viewStates filter (isNonPortableSettingsKey over NON_PORTABLE_SETTINGS_KEYS, the same
predicate Zoo-Code-Org#2226 applies to getConfiguration at its head e9d0a2a) now applies on this branch too:
Zoo-Code-Org#2226 filters what an external caller may read, this chain filters what it may write.
- ClineProvider.spec kept this unit cross-instance doubles and cases (the runExclusiveAcrossInstances
inline manager section, the in-flight-disposal lookup case) around Zoo-Code-Org#1560 timeout-test teardown fix.
- webviewMessageHandler.spec kept this unit deleteCustomMode routing, activateProviderProfile option
typing and isViewLaunched leak guard, around Zoo-Code-Org#1560 sign-out member restore.
- ExtensionStateContext.spec kept this unit two stale-push task-id cases below the 13 cache-interning
and task-identity cases Zoo-Code-Org#1560 restored from main.
- api.ts doc block: main sentence "Invalid values of the display settings are dropped and logged
first" is kept in the paragraph main wrote it in; Zoo-Code-Org#1560 restatement of it in our own paragraph,
which this branch already dropped at 17890eb, stays dropped, so the round trip is documented
once rather than twice.
Verified on the merged tree before committing: src tsc --noEmit exit 0; webview-ui tsc --noEmit
exit 0; eslint --max-warnings=0 clean on all seven touched files with
src/eslint-suppressions.json byte-for-byte unchanged (33814 bytes); prettier --check clean.

ClineProvider 457, sticky-mode 46, sticky-profile 23, webviewMessageHandler 180, api-configuration
17, api-set-configuration 1); webview-ui ExtensionStateContext 45/45, which is Zoo-Code-Org#1560 43 plus this
unit two stale-push cases.
…uration, narrow the rollback
Four findings from the review pool on this head, one reply-only (D, the restored
ExtensionStateContext cases). A, B and C are in the extension API transaction; E is the
webview-side view-state guard; A is a test that promised a behaviour it never performed.
setConfiguration (src/extension/api.ts):
- The existence check, the prior-record read and the save now run inside the manager
cross-instance critical section that the profile rename, the persist path and the
handler deletions already join. Unserialised, the sequence was: we read the name as
absent, another view created it through a locked writer, our own settings or mode write
failed, and our rollback deleted that view record together with its secrets.
- The compensation runs in its own section and re-reads the record first: only the record
whose id this call save returned is this call own to delete.
- The rollback replays only the keys the failed call itself wrote, taken from the snapshot
it captured. A rollback may restore what this call changed and nothing else, because
anything else the snapshot holds belongs to a writer that has moved on since it was
taken. That subsumes the viewStates filter and closes the taskHistory half.
- Re-entrancy audit: nothing inside either section joins the cross-instance queue again.
hasConfig, getProfile, saveConfig and deleteConfig take only the per-instance lock, which
is the inner one, and the settings write goes through ClineProvider.setValues, which
does not join it either. A section that called the sidebar provider persist path or the
rename handler would deadlock, because that queue is a promise chain and is not
re-entrant.
Tests:
- api-configuration: a second view parks inside a real queue double and creates the same
profile name while our call waits behind it; our mode write fails and the rollback
restores that record and its secret instead of deleting it (deleteConfig is never
reached, the id and the apiKey survive).
- api-configuration: the payload writes two keys while another view changes a third shared
key and the pass-through taskHistory key mid-call; the replay carries exactly the two
keys this call wrote and leaves the other view values where that view put them.
- api-configuration: the manager doubles now share a profile-store double in which
hasConfig, getProfile, saveConfig and deleteConfig agree on one map, so the compensation
re-read sees the record this call saved rather than the pre-call answer.
- ClineProvider: the flat-provider-write test now performs the write and asserts the
overlay drop plus the unmasked merged read, instead of naming them in a title.
- webview-ui: the view-state id guard applies the host 64-character bound inclusively, the
test covers 65 (refused) and 64 (reused), and the comment states what the host actually
rejects - an empty id and the proto key - rather than claiming more than it does.
Negative controls, each run against this head with the fix removed:
- record legs unwrapped: both new api-configuration tests fail and the other 18 pass
(ordering assertion trips, and the replay carries four keys instead of two).
- overlay drop removed: the repaired ClineProvider test fails with the stale per-view copy
still served by getValues().
- length bound removed: the 65-character test fails and reuses the too-long id.

Failed pre-merge checks:
- Regression Evidence:
Add a focused browser-wrapper test with `crypto: { randomUUID: undefined }` and
assert the timestamp-random fallback ID. Update the malformed `vscodeState` test
to establish a non-undefined in-memory state before the malformed read, then
assert that `getState()` returns that state without throwing.
- Security Boundaries:
Bind each persisted view-state record to an extension-owned panel or webview
identity, or use a host-validated unforgeable capability for secure
reassociation. Do not authorize a renderer-supplied ID after its provider is
disposed. If secure reassociation is unavailable, clear or retire the durable
record on disposal. Add a regression test that disposes provider A, submits A's
ID through provider B, and verifies that no credential-bearing
`apiConfiguration` is loaded or posted. Redact credential fields before posting
state where possible.
- Persistence Integrity:
Make `activateProviderProfileUnlocked` transactional across manager
selection/record, profile metadata, shared provider settings, mode mapping,
shared selection, and the per-view pin. Snapshot all prior values and the
in-memory view buffer before activation. Await all started writes with an
all-settled failure path. On any failure, compensate every write that landed,
including manager selection and mode mapping, restore the durable view-state map
and in-memory buffer, and rethrow the original error. Add a direct-activation
regression test that rejects the `viewStates` write after manager activation and
verifies that every persistence surface remains on the previous profile.
- Lifecycle Resource Cleanup:
Add a lifecycle generation or cancellation guard to `setViewStateId()` and
`loadViewState()`. Check the guard after each awaited read and immediately
before assigning `viewLocalState`. Return without applying state when the
provider is disposed or the load is superseded. Do not start a disposal-time
load unless it is guarded and necessary. Add a regression test that defers a
profile lookup, starts registration, disposes the provider, resolves the lookup,
and verifies that no stale state is applied.

… section
The unit promises that a failed setConfiguration restores the prior mapping of every mode the
payload touched. The read that captures that mapping sat in the compensation region, below the
manager's cross-instance critical section, so a rejection there aborted the call after the
profile record had already been created or overwritten - the one state the compensation cannot
rebuild, because a record this call created has no prior record to restore.
Lift the capture above the section rather than into it: it joins the fail-closed reads that
precede the save, and it stays outside the cross-instance hold, so it lengthens no lock and the
mode writes it guards still happen after the section, as before.
A payload carrying modeApiConfigs whose getModeConfigId rejects now aborts with saveConfig never
called and the store still holding its prior record and settings (api-configuration.spec 20/20);
at the un-lifted order the same case fails on saveConfig having been called once (19/20).
api-set-configuration 1/1, ClineProvider 457/457 and webviewMessageHandler 180/180 unchanged.

disposeInternal duplicated the teardown releases that dispose()s finally already
owns. Measured on 057e866, a single dispose() ran the diagnostics broker
release, removeAllListeners and McpServerManager.unregisterProvider twice
({"broker":2,"listeners":2,"unregister":2}), and because dispose() returns early
when _disposed is set, a second dispose() changed nothing - so the existing
idempotency test could not see the doubling. The releases now live only in the
finally, which is what the teardown bodys own comment already claimed.
The unawaited `void this.loadViewState()` in the teardown body came from the
merge resolution at 17890eb: neither parent carried it - one occurrence at
:563 on f4, one at :523 on f3, zero on origin/main. Starting a state load
against a provider that is already closing mutates view-local state
mid-teardown with no live view left to deliver to, so it is gone, and the seam
comment beside cleanupStep no longer claims a dispose-time load re-runs the
constructors hydrate.
Tests: the broker release, the listener removal and the MCP unregistration are
asserted to happen exactly once across a double dispose, and dispose is
asserted not to start a view-state load. Control with only the production
change reverted: the count test fails on 2/2/2 and the load test fails on one
call. With the fix ClineProvider.spec.ts is 459 passed, tsc and eslint clean.

previousProfileName must come from snapshotValues, not from replayValues. This issue is still present.
replayValues contains only the keys that forwardValues wrote. Some payloads omit currentApiConfigName, for example { apiProvider, apiModelId } sent while my-profile is active. For those payloads, previousProfileName falls back to "default". savedProfileName also falls back to "default". If a later write then fails, the rollback has two errors:
Line 781 refreshes the overlays pinned to default with the provider keys from the restored snapshot. Those keys belong to my-profile.
The previousProfileName !== savedProfileName block at Line 827 is skipped. Views pinned to the real previous profile do not get their credentials back.
Every rollback test in api-configuration.spec.ts passes currentApiConfigName. No test catches this case.
Add a rollback test with a payload that has no currentApiConfigName.

The id-mismatch branch of the rollback delete still has no test.
At Lines 755-761 of src/extension/api.ts, the rollback skips deleteConfig when currentRecord.id !== savedId. No test reaches that branch:
In this test, hasConfig returns true, so the rollback restores the record and never compares ids.
The makeProfileStoreDouble cases return the same id from getProfile and saveConfig, so they only cover a matching id.
If someone removes the guard, the suite still passes, and a rollback can delete another view's record and its secrets.
Add a test with these steps:
hasConfig returns false, and saveConfig returns "this-call-id".
After the save section ends, another view writes pinned with id: "other-view-id".
setModeConfig rejects.
Assert that deleteConfig is not called and that the record is unchanged.
As per path instructions: "For guards and validators, require tests for both the accept path and the reject path through every public entry point."

Log the dropped focusInput action when the tracked tab has no live provider.
An earlier review thread was resolved because this path logged the drop. The retrieved learning also says that focusInput "logs the dropped action instead of posting it to the sidebar." The current code has no else branch. When tabPanel is set and getTabProvider() returns undefined, the handler returns without a log line. The drop is silent again.
The spec case "focusInput does not post when a tab panel is tracked without a live tab instance" checks only that nothing is posted. It does not catch this regression. Restore the log and assert it in that test.
Proposed fix
if (tabPanel) {
const tabProvider = getTabProvider()
if (tabProvider) {
await tabProvider.postMessageToWebview({ type: "action", action: "focusInput" })
+ } else {+ outputChannel.appendLine("[focusInput] no live provider for the tracked tab panel; dropping focusInput")
}
} else if (sidebarPanel) {
In registerCommands.spec.ts, add this assertion to the dead-tab case:
expect(mockOutputChannel.appendLine).toHaveBeenCalledWith("[focusInput] no live provider for the tracked tab panel; dropping focusInput",)
Based on learnings: "focusInput intentionally does not fall back to the sidebar when a tracked tab panel has no live ClineProvider … so focusInput logs the dropped action instead of posting it to the sidebar."

When writing new code:
- Avoid `as any`; use typed APIs directly (e.g. `RooCodeEventName.X` constants with typed `on()`/`listenerCount()`), or bracket notation (`obj["privateField"]`) to access private members. Prefer precise test doubles or `unknown` with a type guard over double assertions (`as unknown as T`); use double assertions only as a last resort, with a comment explaining why.

2636-2648: Stability & Availability
The deadlock mechanism is real for a nested call on the same secretsKey, but the path from repointViewLocalStateAfterProfileRename to a lock acquisition is not supported. The re-point helpers do not call any lock call site or any caller of upsertProviderProfile or activateProviderProfile. The lock is taken by callers, so the comment's named sources are not lock-taking paths. The residual unread portions are not shown to reach a lock call.
…ough a rollback
Three review rows on the same path:
- registerCommands.ts: a Zoo Code tab open behind another editor in its group is neither
active nor visible, so the dispose handler cleared the tracked ref while a live tab still
existed, contradicting the comment right above it. openClineInNewTab then skipped its reuse
path and focusInput targeted the sidebar. The fallback now takes any live tab; only an
empty set clears the ref.
- extension/api.ts: previousProfileName came from the replay map, which holds only the keys
this call wrote. A payload that never carried currentApiConfigName therefore defaulted the
name to "default", refreshing the overlays pinned to "default" with this profile settings
and skipping the credential replay for the profile that was actually active. It now reads
the snapshot, which is the same value whenever the payload did write the pin.
- api-configuration.spec.ts: the compensation-time id mismatch had no test on its reject
path. A case now creates the name, lets another locked writer replace the record under its
own id between the sections, and fails the mode write: deleteConfig is not called and the
record keeps the other view id and secret. With the guard removed the case fails with
"expected the mock to not be called at all, but actually been called 1 times", so it is
the case the guard needed.
Measured before the changes: the hidden-tab case failed with "expected undefined to be
{ marker: 'panel-A' }" and the omitted-pin case failed with savedProfileName "default"
instead of "my-profile".
registerCommands.spec.ts 63 passed, api-configuration.spec.ts 22 passed, tsc 0 errors,

When writing new code:
- Avoid `as any`; use typed APIs directly (e.g. `RooCodeEventName.X` constants with typed `on()`/`listenerCount()`), or bracket notation (`obj["privateField"]`) to access private members. Prefer precise test doubles or `unknown` with a type guard over double assertions (`as unknown as T`); use double assertions only as a last resort, with a comment explaining why.

The restore branch of setConfiguration's compensation replayed the pre-call record over whatever was in
the store. The id comparison cannot detect the race that follows: saveConfig keeps the existing id when
it overwrites a record, so a sibling view that saved the same name after this call looks identical.
Restoring then replaces that view's committed record - including its secrets - with the pre-call copy.
The record this call wrote is now the reference: the compensation re-reads the current record and
restores only while it still deep-equals what this call saved.
New test: setModeConfig rewrites the record from another writer and then rejects; the rewritten record
and its key must survive. The previous-record test moves to the stateful store double, because a
getProfile mock that always answers the pre-call record cannot model a store that took this call's save.

- Description check:
Add the required template sections. Include an approved issue in the form
`Closes: #<issue-number>`, complete the Pre-Submission Checklist, and confirm
the applicable documentation, contribution, and testing items. Keep the existing
implementation details under Description and the test commands under Test
Procedure; mark non-applicable sections explicitly where needed.
- Regression Evidence:
Add a browser-wrapper test with `globalThis.crypto` set to `{ randomUUID:
undefined }` and assert the deterministic timestamp-random ID. Change the
malformed `vscodeState` test to seed a non-undefined in-memory state before the
malformed read, then assert `getState()` returns that state without throwing and
does not re-read stale storage.
- Security Boundaries:
Bind each persisted view-state record to an extension-owned panel/webview
identity, or require a host-validated unforgeable capability before
reassociation. Do not authorize a renderer-supplied ID after its provider is
disposed. If secure reassociation is unavailable, clear or retire the durable
record during disposal. Add a regression test that disposes provider A, submits
A's ID through provider B, and verifies that no credential-bearing
`apiConfiguration` is loaded or posted. Redact credential fields before posting
state where possible.
- Persistence Integrity:
Make `activateProviderProfileUnlocked` transactional. Snapshot the manager
selection/profile, list metadata, shared provider settings, mode mapping,
durable and in-memory view state, and sibling overlays before activation. Await
all started writes with `Promise.allSettled`; on failure, compensate every write
that landed, restore durable and in-memory view state, and rethrow the original
error. Add a direct activation test that rejects the `viewStates` write after
`activateProfile` and verifies every persistence surface remains unchanged.
- Lifecycle Resource Cleanup:
Add a lifecycle generation or cancellation guard for `loadViewState()`. Check
the guard after each awaited custom-mode or profile read and immediately before
assigning `viewLocalState`. Make `setViewStateId()` stop or ignore delivery when
disposal starts. Add a regression test that defers `getProfile()`, starts
view-state registration, disposes the provider, resolves the profile, and
verifies that no state is applied after disposal.

749-757: Data Integrity & Integration
The restore guard compares the stored record with the unfiltered payload. The restore branch does not run for ordinary payloads.
The open follow-up on the earlier thread still applies at this revision. Line 751 compares currentSettings with values:
currentSettings is the stored profile record without name and id. saveConfig normalizes and schema-filters the payload before it stores the record, so the record holds only provider-settings keys.
values is the full RooCodeSettings payload. It almost always contains non-profile keys, such as currentApiConfigName and modeApiConfigs.
When the payload contains any non-profile key, deepEqual returns false, even if no other view wrote the record. The compensation then logs "another view wrote it after this call saved" and returns. Here is the result: a later setValues or setModeConfig failure leaves the existing profile overwritten with this call's settings and secrets. The function docstring says the prior record is restored.
The test suite does not catch this. makeProfileStoreDouble stores the payload unchanged, so the test "restores the previous record when rolling back a save over an existing profile" passes.
Make these changes:
Capture the normalized record while the first critical section still holds the lock. Call getProfile right after saveConfig, then remove name and id.
In the restore branch, compare the current record with that captured record.
Make the store double filter the payload to provider-settings keys, as production does.
Keep two tests. In the first, no other view writes the record, and rollback restores the old apiKey. In the second, another view rewrites the record, and rollback keeps the newer record.
🐛 Proposed fix
const id = await manager.saveConfig(savedProfileName, values)
- return { recordExisted: existed, previousRecord: priorRecord, savedId: id }+ // The normalized record this call stored, so the compensation compares like with like.+ const { name: _writtenName, id: _writtenId, ...writtenSettings } = await manager.getProfile({+ name: savedProfileName,+ })+ return { recordExisted: existed, previousRecord: priorRecord, savedId: id, writtenSettings }
})
- if (!deepEqual(currentSettings, values)) {+ if (!deepEqual(currentSettings, writtenSettings)) {

Compare the rollback record with the normalized profile values.
saveConfig removes non-profile keys before storing the record, but the rollback comparison uses the raw values object. If a later setValues or setModeConfig call fails, deepEqual(currentSettings, values) can be false even when no other view changed the profile. The rollback then returns without restoring the previous record, leaving the failed call's profile data in storage and contradicting the setConfiguration rollback contract.
The test double in src/extension/__tests__/api-configuration.spec.ts stores raw settings, so it hides this mismatch. Capture the normalized settings produced by the save while holding the same critical section, then compare the current record with that normalized snapshot before restoring.

Draft PR — vps2 unit F4 (cross-instance reset + import invalidation).
Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1561 (this series' gap record; the original upstream bug is #980). Port source: upstream PR #981 (fix(webview): invalidate per-view state after reset and import) — closed draft, superseded by the vps2 series; the fork issue 41 ledger names #981 as the F4 port source.
What this unit does at head 4f60bbf
Budget
Unit delta vs the stack base: 5 files, +342/-1 — well under the 400-soft budget. The PR diff vs upstream/main is larger because the branch is stacked on the unmerged F1-F2 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.
How to test

setViewStateIdnow rejects non-string ids (crafted postMessage), bounds the key length (MAX_VIEW_STATE_ID_LENGTH), and refuses ids already owned by another live instance; a refused view stays on its temporary id against shared state. Regression tests: non-string, oversized, claimed-by-another-view. Negative controls: disabling the ownership check reddens exactly the claim test; widening the length bound reddens exactly the oversized test; restores byte-exact (hash match)._saveViewLocalStateFromMutationpersists the non-secret subset before updating the buffer; the re-key is a single queued write (no delete-then-write window; authorship clears only after the write lands); the mutation hook keeps the buffer synced across setValue/setValues and profile upsert/activation/deletion.--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.upsertProviderProfilewithactivate=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 throughupsertProviderProfileso 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 onlyapiProviderfalling back to shared state.--max-warnings=0clean, tsc clean except the two known local telemetry-dist noise lines, prettier merge-ref gate ALL-MATCHED.Follow-up: overlay read from the view buffer (required-lane fix)
The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw
apiConfigurationstate key. That key is a partial patch written by shared-store paths, not a view snapshot: with no overlay present and the raw key partial,getState()served only the partial object and dropped the shared provider settings the previous merge produced (the parallel-mode activation tests caught exactly this - the activated profile's model id vanished; required lane red on the units carrying that spec). The overlay is now read from the view buffer itself, where a present value is by contract a complete profile and an absent one means the shared store serves the settings.Proofs: ClineProvider.parallelMode.spec green where present (the six synchronization tests that regressed), ClineProvider.spec green including the overlay-completeness tests, sticky-mode and webviewMessageHandler green; negative control: reverting the overlay to a shallow merge over the shared settings still reddens exactly the leak test; restores byte-exact (hash match); eslint

A review round on the view-identity unit found that the non-activating-save refresh updated pinned views' buffers but not their active tasks' API handlers, and the posted state prefers the task's own
apiConfiguration: a conversation running in a view pinned to the saved profile kept sending the old token (e.g. after the Zoo Gateway callback rotated it) even though the view's buffer had caught up. The refresh now rebuilds the affected tasks' handlers in the pinned views, and the non-activating branch rebuilds this view's own handler when it holds the pin.Proofs: ClineProvider.spec green (the pinned-sibling refresh test now asserts the active task's handler is rebuilt with the saved settings, not just the private buffer); negative control: dropping the rebuild from the refresh reddens exactly that assertion, restores byte-exact (hash match); parallelMode/sticky-mode/webviewMessageHandler green; eslint

The review round on the api-wiring unit named four test-quality issues; the ones present in this unit are fixed here: the
viewStatesdescribe block moved out of thealwaysDenyUnapprovedCommandsblock (test names carried the wrong subject), the prune test'stoBeDefined()survival checks replaced with exact-shapetoEqualassertions (they pass even if pruning strips fields), the stale-temporary-entry test's fixed 10 ms wait replaced with awaiting the load itself (the negative assertion could pass vacuously on a slow load), and the readiness-cancel test's fake timers restored in afinallyblock (a failed assertion left fake timers active and hung a later real-timer test).Proofs: global-settings 9/9 where present, ClineProvider.spec green, sticky-mode green where present, api-task-control green where present; negative controls: pruning that strips

A review round on the mode-profile-writes unit found fixes this unit carries. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
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.Proofs: ClineProvider.spec 287/287, sticky-mode 34/34 (new pin-write-failure rollback test), parallel-mode 37/37 (sibling re-pin test asserts the task handler rebuild and sticky-name re-point); negative controls: dropping the rollback call reddens exactly the rollback test, dropping the rebuild reddens exactly the re-pin test, restores byte-exact (hash match); eslint
--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.Updated this round (CodeRabbit follow-up, head 574dfeb)
handleModeSwitchUnlockednow reconciles every write it owns (shared mode, durable view pin, task mode, task history) when a failure lands after the task-mode write - including the mode-linked profile activation - sosubmitUserMessagedelivers the submitted message on the pre-switch mode and profile instead of a half-applied switch. Regression test fails the activation after the task-mode write and asserts all four stores are restored (negative control: reverting the reconcile reddens exactly that test).taskApiConfigName); regression tests cover both sites.afterEachdisposes the per-test provider before resetting the instance registry; the webview state-payload test renamed to describe what it asserts.Updated this round (CodeRabbit follow-up 2, head 1849e73)
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); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.Updated this round (CodeRabbit follow-up 3, head c40a67a)
