Part of the vps2 durable per-view state series —. Unit F2c of the F2 split; supersedes upstream PR 1555. Stacked on F2b. Content source of record: kind: commit, base 8554307ec -> head bff2a5ca8 (upstream PR 1555).

Budget: 739 a+d standalone — over the soft 400 cap, under the hard 1000 cap. Rationale: one cohesive regression suite whose ~588 lines are shared mock setup for three describes; splitting the file would duplicate the setup rather than reduce what a reviewer reads.

Description

How this unit implements durable per-view state, and the choices reviewers should check:

• Per-view identity. Each ClineProvider starts with a host-generated temporary id (sidebar-3) and, on webviewDidLaunch, adopts the stable id the webview persists through acquireVsCodeApi().setState() (webview-ui/src/utils/vscode.ts). The id is sanitized to [A-Za-z0-9_-] and __proto__ is rejected so it stays a safe object key in the shared map.
• Durable viewStates map. mode and currentApiConfigName are stored per view id under the new viewStates global-state key (packages/types/src/global-settings.ts). Every write goes through one serialized write queue that re-reads the map fresh and merges into the existing entry, so concurrent views cannot clobber each other; entries with nothing persistable are deleted and stale entries are pruned.
• Re-keying. Writes captured while the provider still holds its temporary id persist under that id and are re-keyed to the stable id when the webview registers one, so a change made before the launch message stays durable. A failed registration restores the previous id so a later launch retries.
• Overlay composition in getState(). The view-local buffer is layered over the shared ContextProxy values; fields mutated while the async profile lookup is in flight are re-applied field by field, so a slow load cannot clobber a newer user selection.
• Cache/storage atomicity. ContextProxy#updateGlobalState fills the in-memory cache before awaiting globalState.update, so the three viewStates writes now go through writePersistedViewStates, which restores the previously cached map when the storage write rejects instead of leaving other views reading an uncommitted map.
• viewStates is excluded from settings import/export so a per-window view map is never transferred between machines.
• Title-bar command routing (src/activate/registerCommands.ts): title-bar commands target the click-origin instance, and overlapping openClineInNewTab calls are serialized.

Test Procedure

pnpm --dir src vitest run core/webview core/config core/task activate
pnpm --dir webview-ui vitest run src/utils/__tests__/vscode.spec.ts src/context/__tests__/ExtensionStateContext.spec.tsx

• ClineProvider.parallelMode.spec.ts — multi-tab isolation: two views with different ids keep separate mode, profile pin and apiConfiguration.
• ClineProvider.spec.ts → setViewStateId, persisted view state pruning, view state persistence edge cases — merge/clear/prune semantics, corrupted storage values treated as an empty map, re-keying of pre-launch writes, and the cache rollback when the storage write rejects.

Further narrative detail (per-hunk ownership evidence, follow-up dispositions, negative-control records) lives in the review thread, not the description, to satisfy the description length gate.

Split-unit issue reference

No approved upstream issue exists for this change. This pull request is one unit of a declared split of a larger change, and the split plan, the unit boundaries and this unit's acceptance criteria are recorded on the tracking issue in this repository: #1992. That issue is the home for this unit's review dispositions and follow-up registrations, which is why no approved issue is linked above.

Updated this round (head 60d6561)

• Merged upstream/main 839fd6c. One conflict: src/services/skills/SkillsManager.ts. Both sides reviewed: main refactored watcher creation into a shared createSkillsWatcher plus a container-watcher system; this unit adds a pre-creation isDisposed guard so a watcher created after dispose() drained the disposables does not stay registered for the session. The resolution keeps main's structure and ports the guard into createSkillsWatcher, which covers both the watchDirectory and syncContainerWatchers creation paths; the unit's initialize() guard survived the auto-merge.
• Ported the shared-code fix from the sibling unit at 8a43f2b: deleting the active profile now completes the activation-side effects the old deleteApiConfiguration -> activateProviderProfile path performed (manager current-profile record, current-mode mapping, current task API handler rebuild, sticky profile, ProviderProfileChanged emit), with its two tests and the manager doubles.

Verification numbers (head 60d6561)

• ClineProvider.spec 301/301, SkillsManager.spec 95/95, webviewMessageHandler.spec 92/92, ClineProvider.sticky-mode.spec 31/31, ClineProvider.sticky-profile.spec 18/18, ProviderSettingsManager.spec 60/60
• Negative control on the ported block: removing it reddens exactly the rebuild test (1 failed / 300 passed); restore byte-exact (hash match)
• tsc: only the two known local telemetry-dist noise lines (CI builds types from source); eslint --max-warnings=0 clean on touched files; suppression counts unchanged vs both merge parents
• Prettier merge-ref gate ALL-MATCHED

Cancelled-switch pin fix (head 6378845)

• AT-HEAD thread 4252409834 (Minor, data integrity): the compensation for a cancelled mode switch restored the shared previous mode through setValue, which also repinned the acting view to the shared value. Fixed: the acting view's own pin is captured before the switch and the two stores are restored separately, mirroring compensateProfileActivation's shared/pin split; an unpinned view is restored to unpinned.
• Proofs at 6378845: sticky-mode 32/32 (new regression test), ClineProvider.spec 301/301, webviewMessageHandler.spec 92/92, ProviderSettingsManager.spec 60/60; negative control 1-red / restore-hash MATCH; tsc clean except the two known local telemetry-dist noise lines; eslint clean; prettier merge-ref gate ALL-MATCHED.

Post-commit activation error distinction (head 5c7f5f0, port)

• Ported the sibling unit's fix for AT-HEAD thread 4251990874 (same deletion code): post-commit activation failures now post the committed state and throw a distinct ProfileDeletionActivationError; the handler warns instead of reporting a failed deletion.
• Proofs at 5c7f5f0: ClineProvider.spec 302/302, webviewMessageHandler.spec 93/93; negative controls 1-red each, restores byte-exact (hash match); tsc 0; eslint clean; prettier merge-ref gate ALL-MATCHED.

CR round: non-activating-save refresh + overlay completeness (head 319cba7)

This unit already implemented both behaviors the review round named on the get-state unit (non-activating saves refresh views pinned to the saved profile; the pinned overlay is used as a complete profile snapshot with only an apiProvider fallback). The round's two regression tests now land here as a test-only commit; the cloud instance doubles gained on/off handlers because provider dispose detaches the settings listener against the getter those tests leave in place.

• 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 (already asserted here).
• 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 319cba7: 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: mutation queue keeps ownership until the timed-out mutation settles (head 4350d18)

The queue advanced from the timeout-bounded result, so a caller-facing timeout released the next queued mutation while the previous one was still awaiting its profile load; the abort signal is advisory, so a late durable write could interleave with the successor. The queue now chains to the underlying run promise (matching the deletion unit's implementation): the timeout releases the caller, not the queue; the pre-activation signal check stays.

Proofs: ClineProvider.spec 305/305 (new test: the queue hands over only once the running mutation settles while the caller is released at the timeout); negative control: advancing the queue from the timeout-bounded result reddens exactly that test, restores byte-exact (hash match); parallelMode 18/18, sticky-mode 32/32, webviewMessageHandler 93/93; eslint --max-warnings=0 clean; tsc clean; prettier merge-ref gate ALL-MATCHED.

Follow-up: active task handlers rebuilt on non-activating saves (head 6b1d046)

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 9bdac41)

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 b375467)

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.

Follow-up: review-round fixes from the series (head 2e932e8)

A review round on this unit found two cross-instance integrity issues: (1) the profile-mutation queue belonged to each provider while profile mutations rewrite the shared ContextProxy stores - a second view could commit between the first view's shared write and its snapshot compensation, and the compensation restored a stale copy over the newer write; the queue is now shared across instances. (2) The sibling re-pin switched each successful view's task to the replacement's API handler and sticky profile name inside the per-sibling loop, so a later sibling's rejection rolled the pins back but left the tasks on the replacement profile after the deletion failed; task updates now run only after every sibling's re-pin landed.

Proofs: ClineProvider.spec 306/306 (new cross-instance serialization test), parallel-mode 19/19 (new sibling-task rollback test), sticky-mode 32/32; negative controls: a per-instance queue again reddens exactly the serialization test, pre-check task updates redden exactly the sibling-task test, byte-exact restore (hash match); tsc clean, eslint --max-warnings=0 clean, prettier merge-ref gate ALL-MATCHED.

---

Updated this round (CodeRabbit follow-up, head 91c3bfa)

• Non-activating profile saves no longer force-rebuild the API handler of a view whose active task follows a different sticky profile: the refresh rebuild site is guarded by pinned === name && taskApiConfigName === saved profile (the include-self refresh covers the acting view); pinned-view overlays still refresh. Regression tests cover the pinned-sibling and acting-view cases (negative control: removing the guard reddens exactly those two tests - this unit has a single rebuild site).
• Test hygiene: prune assertions compare full kept entries; the webview state-payload test renamed to describe what it asserts.
• Verified: ClineProvider.spec 308 green, sticky-mode 32 green, parallelMode 19 green, eslint --max-warnings=0 clean, tsc 0 errors, prettier clean.

---

Updated this round (CodeRabbit follow-up 2, head d86aea7)

• Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite (post-loop task pass in this unit's compensated re-pin) now require taskApiConfigName === deleted profile (the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test).
• Verified: ClineProvider.spec 309 green, sticky-mode 32 green, parallelMode 19 green, eslint --max-warnings=0 clean, tsc 0 errors, prettier clean.

---

Updated this round (CodeRabbit follow-up 3, head 717b0ea)

• Aborted deletions now compensate: the queue stays owned until the timed-out run settles, so the skip-compensation branch in the deletion catch was stale - it could leave the settings deleted while the profile list, the shared selection, or a view pin still named the deleted profile. The abort checkpoints route through the same store-by-store rollback a rejected write gets; the stale queue-advance comments in the deletion and upsert paths are corrected. The deletion-abort regression test now asserts the settings restore and the rolled-back profile list (negative control: restoring the skip branch reddens exactly that test).
• Test hygiene: every ClineProvider a profile-mutation test creates is now disposed (finally block in the three-provider re-pin test; after the final assertions elsewhere) so leaked instances cannot be reached by later tests' sibling-scanning paths.
• Verified: ClineProvider.spec 309 green, parallelMode 19 green, sticky-mode 32 green, eslint --max-warnings=0 clean, tsc 0 errors, prettier clean.

---

Note for reviewers (j-wave scope)

• The mode-switch reconcile-clobber defect class (sibling PRs, follow-up 3 there) does not apply to this unit: handleModeSwitchUnlocked here has no reconcile region (the mode-switch rollback mechanism lives in the mode-profile-write units), and this unit's mutation queue chains the timed-out run, so a late continuation cannot overlap the next queued mutation. No code change needed on this unit for that class.

Stryker suppression comments removed

Per the AGENTS.md policy (never add Stryker directives; remove them when a file is touched), all // Stryker disable directives were dropped from this PR. Equivalence rationale for the removed suppressions:

• Stryker disable next-line ConditionalExpression: defensive clobber guard, unreachable per the ordering argument above.
• Stryker disable next-line StringLiteral: setPanel branches only on type === "sidebar", so any other literal routes to the identical tab-ref assignment
• Stryker disable next-line StringLiteral: setPanel only distinguishes "sidebar"; any other value routes to the tab-ref assignment
• Stryker disable next-line ConditionalExpression,BlockStatement: hostile non-stabilizing encodings are unreachable from the webview (its posts are plain link targets); the bound is defensive
• Stryker disable next-line CallExpression: hostile non-stabilizing encodings are pinned by the direct decodeUntrustedPathToStable bound test; the webview never posts such values
• Stryker disable next-line ConditionalExpression,OptionalChaining: equivalent mutant - when localStorage is unavailable the guard-false path and the throwing body both return this.fallbackState from this catch
• Stryker disable next-line ConditionalExpression,OptionalChaining: equivalent mutant - when localStorage is unavailable the guard-false path and the throwing body both mark the write failed and return newState

CR round 2026-10-14 (second pass)

• ClineProvider.parallelMode.spec.ts: the sibling-view-consistency block now builds its own extension-context/output-channel doubles and initializes the telemetry singleton inside its beforeAll, so the block passes when run alone (vitest -t) instead of relying on a leftover mockContext from an earlier test's beforeEach.
• ClineProvider.spec.ts: the activation-buffer regression test's providerSettingsManager double now provides getProfile (not-found = creation case) and getModeConfigId, so snapshotProfileActivationStores succeeds and the activation path the test names actually executes; breaking the buffer-clear ordering reddens exactly that test.

Row-9 update (head c040c8b)

• Activation writes from the stored record (read-back feeds every post-save consumer; CR Security Boundaries).
• Re-point cache rollback: repointPersistedViewStates restores the cache to the durable value when the write rejects (the clear path already rolls back through the shared write helper; CR Persistence Integrity).
• Deletion re-points closed views' durable pins onto the surviving profile, with landed-flag compensation (CR Persistence Integrity).

Verification: new tests are focused negative controls (reverting each guard reddens exactly the matching test); ClineProvider.spec, webviewMessageHandler.spec spot-checks, api specs, spec-inclusive tsc --noEmit, eslint --max-warnings=0 (suppression counts unchanged) and prettier all green on this head.

Upstream refresh (head c040c8b)

Merged the current upstream/main (merge commit; the row-9 fix commit is unchanged and is the first parent) to clear the review gate's mergeability hold. Upstream refactored upsertProviderProfile into a new persistProviderProfile method and added a runToCompletion queue option; this unit's transactional body was ported into the new method unchanged and upstream's Promise.allSettled activation fix was adopted in it. One deliberate adaptation: upstream opts upsertProviderProfile into runToCompletion; this unit does not, because its contract is the landed-write compensation - the mutation timeout must abort the run so the compensation rolls the record and the stores back, which is what the cancellation tests pin. ClineProvider.spec, webviewMessageHandler.spec, tsc --noEmit, eslint (suppression counts unchanged) and prettier re-verified green at this head. The first refreshed head's windows unit-test lane caught that upstream's new updateProfileModel tests in ClineProvider.apiHandlerRebuild.spec.ts mock the settings manager with a static getProfile, which starves the post-save read-back; the mock now repoints getProfile at what saveConfig wrote (the real manager's behavior), and the file's 38 tests pass locally alongside the rest of the verification set. Three of upstream's new tests are adapted to this unit's abort-and-compensate upsert semantics (documented in comments): the timed-out upsert cancels and rolls back instead of running to completion, and the restore-path tests account for the compensation's record rollback and the serialized write order.

Three review threads addressed

• No provider sharing across API task requests — openClineInNewTab-style coalescing is now UI-only. ClineProviderFactory.createInNewTab() (the API.startNewTask({ newTab: true }) path) calls a new openClineInNewTabForApi, which serializes creations but never shares one provider: every independent API request gets its own panel and provider, so neither task can evict the other. reuseTrackedPanel is disabled on that path.
• Merge instead of overwrite in the inner rollback — the scoped compensation after a failed persisted-pin re-point now re-reads the durable map and restores only the entries that named the deleted profile in the pre-delete snapshot; concurrent sibling writes (e.g. saveViewState("mode")) survive.
• Committed deletion survives a failed state post — both trailing postStateToWebview() calls are now best-effort (logged, not rethrown): a post failure after the deletion committed can no longer reach the outer compensation and resurrect the profile. Added a test where the post rejects after a successful non-active deletion: deleteConfig ran once, saveConfig was never called, and listApiConfigMeta no longer contains the deleted entry.

Local: registerCommands.spec.ts 55 passed (includes the new independent-API-provider test); tsc clean for the touched files. The large ClineProvider.spec.ts cannot load in this shared worktree because its @roo-code/types junction points at another worktree's newer types (zod/schema mismatch); the new test is type-checked and will run in CI.

Review comments at @src/activate/__tests__/registerCommands.spec.ts:
- Around line 746-747: Update the assertions in the test around the two API
requests to verify that the provider instances are distinct; retain the existing
definedness checks and assert that the second provider is not the same object as
the first.

Review comments at @src/core/webview/ClineProviderFactory.ts:
- Line 15: Update the ClineProviderFactory.spec.ts mock and all three
createInNewTab tests to use the openClineInNewTabForApi export for mock setup,
configured return values, and call assertions, matching the API used by
ClineProviderFactory.

Timestamp: 2026-10-10T11:26:30.658Z
Learning: In src/activate/__tests__/registerCommands.spec.ts, tab-tracking tests must preserve vscode.WebviewPanel object identity and match provider lookups by reference, not marker fields. To test the inactive-panel guard, send an inactive event for a different panel object from the tracked panel and assert that getPanel() retains the tracked object. An event for the already-tracked panel cannot detect removal of the active guard.

## ESLint Suppressions

When writing new code:

- Avoid floating promises; add `void`, `await`, or `.catch()` as appropriate.

Applied to files:

• src/activate/__tests__/registerCommands.spec.ts

[easonLiangWorldedtech]

Both follow-up threads addressed

• Provider identity — the API tab-creation test now reads vi.mocked(ClineProvider).mock.results and asserts each caller received a distinct constructed provider (created[0] === first, created[1] === second, first !== second); sharing the first provider would fail.
• Factory test mock — ClineProviderFactory.spec.ts now imports/mocks/configures openClineInNewTabForApi (not the UI-only openClineInNewTab) and asserts it was called with the injected dependencies, so the focused suite exercises the new API path.

Local: registerCommands.spec.ts + ClineProviderFactory.spec.ts 58 passed.
