fix(webview): isolate parallel mode and provider profile writes (vps2 F3) by easonLiangWorldedtech · Pull Request #1560 · Zoo-Code-Org/Zoo-Code

easonLiangWorldedtech · 2026-09-07T02:38:30Z

Draft PR — vps2 unit F3 (mode/profile writes).

Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1559 (this series' gap record; the original upstream bug is #978). Port source: the F1c-head-to-CS residual, cross-checked against upstream PR #979 (fix(webview): isolate parallel mode and provider profile writes) — closed/superseded by the vps2 series; the fork issue 41 ledger names #979 as the F3 port source.

What this unit does at head `ca61d20`

src/core/webview/ClineProvider.ts — the webview delete-path (deleteProviderProfile + repointPersistedViewStates), loadViewState dead-mode-pin validation, the handleModeSwitch profile-write isolation (per-view upsert/activate instead of the shared write), the as-any cast drop in delegateParentAndOpenChild, and a 3-line Stryker exclusion comment above the no-op listApiConfigMeta view-state write (two equivalent mutants). This round also: dispose() runs every cleanup step independently (per-step try/catch, first error preserved and rethrown after all steps run, individual disposables isolated) — the CR Major finding fix; and 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/task/Task.ts + Task.spec.ts — the task-side per-view mode/profile write: mode switches route through provider.handleModeSwitch and the submitted message is kept on failure.
src/core/tools/SwitchModeTool.ts + switchModeTool.spec.ts — the tool-side per-view write port.
src/core/webview/webviewMessageHandler.spec.ts — ported mock surface only (4 mock fields + defaultModeSlug import); webviewMessageHandler.ts itself is 0/0.
sticky-mode / ClineProvider / parallelMode specs — per-view assertions, the CS F3 describes, and the mutation-killing tests; this round the sticky-mode persisted-view-state-keys suite, rollback tests and the re-key ownership adaptations are ported in, and every ClineProvider construction passes the shared WebviewFocusTracker.
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: 10 files, +919/-65 (a+d 984 vs the 400-soft / 1000-hard budget: soft-over, hard-under; the unit carries the production isolation logic). The PR diff vs upstream/main is 33 files (+9186/-511) 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

vitest run src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts — per-view mode/profile isolation, delete-path repointing, dispose cleanup-branch sequence.
vitest run src/core/webview/__tests__/ClineProvider.spec.ts -t "active instance tracking" — dispose step isolation (early-step failure runs later releases and reports the first error).
vitest run src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts — per-view viewStates keys + the ported persisted-view-state-keys suite.
vitest run src/core/tools/__tests__/switchModeTool.spec.ts src/core/task/__tests__/Task.spec.ts — tool/task-side per-view writes.

Verification numbers (head `ca61d20`)

vitest: ClineProvider.spec 288/291 (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); sticky-mode + registerCommands + parallelMode + webviewMessageHandler + flicker-free-cancel + api-set-configuration 221/221; 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 controls: flipping the first-error guard in the new cleanupStep reddens both dispose tests; forcing the re-key ownership check to true reddens sticky-mode "does not merge a stale temporary-id entry"; both restored byte-exact (sha256 match).
Prettier: full-repo check passes on the PR merge tree (merge ref cddc7d7).

Updated this round (`d2faa7e` -> `ca61d20`)

Merged upstream/main 793b65b; resolved 5 conflicts with both-sides review (registerCommands + spec, ClineProvider + spec, ExtensionStateContext.spec.tsx).
Fixed the CR Major finding: dispose() cleanup steps are now isolated (per-step try/catch, first error preserved and rethrown after all steps run, individual disposables isolated); new regression test "runs every later cleanup step when an earlier step rejects" (mcpHub.unregisterClient rejects; customModesManager.dispose and taskHistoryStore.dispose still run); existing cleanup-failure test updated for the per-step log wording. Thread replied and resolved.
Ported the F1a view-identity review fixes into this unit's ClineProvider copy; adapted the three 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 88 ClineProvider.spec and 40 parallelMode.spec constructions; api-set-configuration.spec passes the required ClineProviderFactory.
Suppression count ClineProvider.spec.ts 196 -> 194.

Mutation gate (carried)

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). The dispose-isolation change is covered by the two dispose tests plus the negative control above.

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.

Pre-merge ERROR-row pre-check (head `9c2bee3`)

Security Boundaries / view-state id rows: addressed at 9c2bee3. 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 9c2bee3: 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 fe00539: 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 `a5a2f60`)

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 `b68744c`)

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 `390c0d4`)

A review round on this unit produced three fixes. 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).
The fallback deletion path's re-check of whether this view pinned the deleted profile was unreachable (a view pinned to the deleted profile takes the activation path above and returns); the dead branches are removed, behavior-preserving (spec green).
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 293/293, sticky-mode 34/34 (new pin-write-failure rollback test), parallel-mode 34/34 (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 08c6fcb)

Mode-switch atomicity (ported from the sibling unit): handleModeSwitchUnlocked 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 included.
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.
Verified: ClineProvider.spec, sticky-mode and parallelMode suites green, eslint --max-warnings=0 clean, tsc real=0, prettier clean; negative controls: removing either rebuild guard reddens exactly its test, reverting the reconcile reddens exactly the activation-rollback test.

Updated this round (CodeRabbit follow-up 2, head c820dd0)

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.
Verified: ClineProvider.spec 296 green, sticky-mode 35 green, parallelMode 34 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

Updated this round (CodeRabbit follow-up 3, head 0b08bb0)

Mode-switch reconcile: 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 new profile), and also when the mutation signal has aborted (the queue has advanced; a newer mutation may own the mode stores - this is the fix requested on the PR thread). 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).
Verified: sticky-mode 38 green, ClineProvider.spec 296 green, parallelMode 34 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

📝 Summary

Summary by CodeRabbit

New Features
- Mode, provider-profile, and API configuration selections are saved per webview, allowing editor tabs to maintain separate settings.
- Editor-tab actions for starting a task, opening settings, browsing the marketplace, and viewing history now target that tab.
- Webview state can be restored across launches when supported.
- Opening a task in a tab reuses the existing tab when available.
Bug Fixes
- Mode changes apply to the intended task, and message delivery continues if switching fails.
- Browser-based state recovery is more resilient when local storage is unavailable.
- Deleting a nonexistent provider configuration now reports a specific error.
Other Changes
- Webview-specific state is excluded from global settings imports and exports.

The pull request adds persisted per-view mode and profile state, task-aware mode switching, and editor-tab-specific commands. It also changes configuration import and export behavior and updates launch handling, profile synchronization, and tab-panel tracking.

Changes: Per-view state and profile settings

Layer / File(s)	Summary
View-state contract and stable identity `packages/types/src/global-settings.ts`, `packages/types/src/vscode-extension-host.ts`, `webview-ui/src/utils/vscode.ts`, `webview-ui/src/context/ExtensionStateContext.tsx`, `webview-ui/src/utils/__tests__/`, `webview-ui/src/context/__tests__/`, `packages/types/src/__tests__/*`	The settings schema and launch message support view-state data and an optional view ID. The webview generates and stores a sanitized ID, with browser-storage fallback handling.
Persisted view state and merged settings `src/core/webview/ClineProvider.ts`, `src/core/webview/__tests__/ClineProvider.*.spec.ts`	`ClineProvider` persists mode and profile selections by view ID, limits stored entries to 50, restores valid values, overlays local state on shared settings, and clears the view entry on reset.
Profile lifecycle and settings integration `src/core/webview/ClineProvider.ts`, `src/core/webview/webviewMessageHandler.ts`, `src/core/config/`, `src/extension/api.ts`, `src/extension/__tests__/`, `src/eslint-suppressions.json`	Profile operations synchronize affected views. Launch handling registers view IDs and repairs invalid profile selections. Import and export omit `viewStates`, settings writes use provider-level methods, and missing-profile deletion has a distinct error type.

Task-scoped mode switching

Layer / File(s)	Summary
Task-targeted mode-switch flow `src/core/task/Task.ts`, `src/core/tools/SwitchModeTool.ts`, `src/core/webview/ClineProvider.ts`, `src/core/task/__tests__/Task.spec.ts`, `src/core/tools/__tests__/switchModeTool.spec.ts`, `src/core/webview/__tests__/ClineProvider.*.spec.ts`	Task submission and the switch-mode tool pass the target task to mode handling. Mode changes validate slugs and apply task- and view-scoped effects according to focus and cancellation state. Cancellation checks protect task-history updates, with rollback handling for interrupted writes.

Editor-tab commands and panels

Layer / File(s)	Summary
Tab-specific command routing `packages/types/src/vscode.ts`, `src/package.json`, `src/activate/registerCommands.ts`, `src/activate/__tests__/registerCommands.spec.ts`	New command IDs and editor-title contributions route task, settings, marketplace, and history actions to the tracked tab provider. Sidebar actions target the activation-time provider, and focus targets the tab when one is tracked.
Tab creation and panel tracking `src/activate/registerCommands.ts`, `src/activate/__tests__/registerCommands.spec.ts`	Overlapping tab opens share a creation promise. Opening reuses and reveals a tracked tab with a live provider, while activation and disposal update the tracked panel reference.

Change: Bug fix

Merge Risk: 🔵 Low · up to c820d

The per-view mode and profile isolation is largely in place. In one rare case, a timed-out mode switch can later undo a newer switch and leave a mode the user did not choose. The change can merge with a small follow-up to skip that rollback after a timeout.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to d2faa

Parallel views can select different provider profiles, but overlapping profile changes may leave a view showing one profile while using settings from another. The affected scope is the extension's views and configured provider connections, not a demonstrated cross-user or cross-tenant boundary.

Retained concerns

Medium · security · inferred: Overlapping profile activations can leave a view pinned to one profile name while its configuration falls back to another view's shared provider settings. A local overlay is also merged over, rather than substituted for, those shared settings. This can undermine the intended isolation of provider credentials and destinations across parallel views.
Low · architecture · inferred: Launch registration accepts a renderer-supplied view ID without binding it to the receiving view. If a renderer supplies another valid ID, it can load and later write that ID's persisted mode or profile pin. Practical targeting depends on learning or colliding with an ID; this does not establish new access to profile secrets, which existing renderer commands can already select.

Security review details

Security Blast Radius

inferred — The independently affected scope is multiple views in one extension host and their configured provider connections. A profile/settings mismatch could cause a view or subsequent task to use an unintended provider configuration; the evidence does not establish cross-user, cross-tenant, or deployment-wide exposure.

Security Findings and Attack Paths

inferred — Two live views can initiate overlapping profile activations. Because their mutation queues are separate, one activation can clear its own overlay after the other has taken a sibling snapshot, leaving its pinned name backed by the final shared settings. No concurrent two-provider activation test or runtime trace was available to establish frequency.

Trust Boundaries and Controls

observed — Launch forwards a renderer-provided ID into state restoration. Sanitization, random default IDs, stale-load checks, and invalid-mode handling constrain the path, but none binds a supplied valid ID to its view. Existing renderer profile-selection commands limit any claim of newly gained secret-reading authority.

Resilience and Maintainability Implications

observed — Serialized persisted-state writes, stale-load suppression, focused-task gating, and sibling refresh provide meaningful counterevidence for ordinary sequential operation. They do not establish atomic cross-view profile activation or recovery from a partially completed activation.

Hardening Proposals

proposed — Keep the selected profile name and complete configuration together as a view-owned value, or serialize shared-setting replacement across providers and reconcile overlays after failure. Bind stable-ID restoration to the receiving view rather than treating a sanitized renderer-supplied ID as ownership proof.

Full details: Security Boundaries

Explanation

The changed launch path trusts a client-supplied view identity and can disclose provider secrets. webviewMessageHandler.ts:583-595 passes message.viewStateId to ClineProvider.setViewStateId. ClineProvider.ts:746-811 normalizes the value and rejects only IDs held by a live provider; it does not bind the ID to the receiving WebviewPanel or WebviewView. Disposal removes the provider from activeInstances at ClineProvider.ts:1382-1384, while the changed retention behavior preserves the persisted entry. A compromised webview that knows a disposed view's ID can launch with that ID, load its persisted profile through loadViewState (ClineProvider.ts:819-865), and receive the complete profile snapshot through getState and postStateToWebview (ClineProvider.ts:3994-4003, 3414-3419). Profile data can include apiKey (packages/types/src/provider-settings/anthropic.ts:15-20).

Resolution

Do not use the client-supplied viewStateId as the authorization boundary. Generate or register the identifier in the extension host and bind each identifier to its owning WebviewPanel or WebviewView. Reject launch messages when the supplied identifier is not bound to the receiving view, including after the original provider is disposed. Also redact secret provider fields from webview state unless the UI requires them.

Full details: Persistence Integrity

Explanation

The prior persistence-integrity failure remains. The PR adds a compound path: webviewMessageHandler calls provider.setValue at src/core/webview/webviewMessageHandler.ts:892-895, and ClineProvider.setValue writes shared state before the per-view write at src/core/webview/ClineProvider.ts:4180-4185. If globalState.update rejects, ContextProxy.updateGlobalState has already changed stateCache at src/core/config/ContextProxy.ts:366-372; the per-view write is skipped and no rollback runs. ClineProvider.setValues has the same unguarded initial write at src/core/webview/ClineProvider.ts:4231-4236, while ContextProxy.setValues uses Promise.all at src/core/config/ContextProxy.ts:561-564, so one rejected key can leave other keys persisted. The changed path can therefore leave the cache, durable global state, and viewStates inconsistent.

Resolution

Make ClineProvider.setValue and setValues transactional. Snapshot shared values, the ContextProxy cache, the view-local buffer, and the prior persisted view-state entry. Roll back every changed store when either the shared write or view-state write fails, including an initial shared-write rejection. Serialize multi-key writes so setValues cannot partially persist keys. Preserve the original error and report rollback failures. Add tests for rejected shared writes and partial setValues writes that verify durable global state, the ContextProxy cache, view-local state, and viewStates remain unchanged.

Full details: Lifecycle Resource Cleanup

Explanation

The cancellation defect remains in the changed mode-switch path. handleModeSwitchUnlocked awaits saveViewState("mode", newMode) at ClineProvider.ts:2397-2404, but saveViewState and _persistViewLocalStateFromMutation accept no AbortSignal and can remain blocked in savePersistedViewState at :579-629. If that write lasts beyond the 30-second timeout, enqueueProviderProfileMutation aborts the caller and advances its queue at :281-309, while the original operation continues. When the write resolves, the cancelled switch proceeds to setValue, ModeChanged, metadata writes, and profile activation because there is no signal check after the awaited view-state write. A later mode switch can therefore overlap with and be overwritten by the cancelled switch. The added cancellation tests cover a deferred task-history write, not a deferred view-state write.

Resolution

Pass the mutation signal into saveViewState and the persisted view-state write helper. Check the signal after every awaited write and before shared writes, events, metadata writes, and profile activation. Do not advance providerProfileMutationQueue until the underlying mutation stops, or compensate every post-cancellation write. Add a deferred saveViewState regression test that verifies a cancelled switch emits no event, activates no profile, and cannot overwrite a later switch.

…en view-identity tests Track the in-flight tab panel creation with a module-level promise so concurrent openClineInNewTab calls reuse one panel and provider (adds a Promise.all regression test). ClineProvider.spec sets the private view via the public resolveWebviewView() instead of a ts-ignore assignment. registerCommands.spec types evictCurrentTask/refreshWorkspace on the fixture and drops the as any attachment. eslint-suppressions: prune the registerCommands.spec.ts entry (two as any suppressions removed).

…n the concurrency assertion

…-bar posts - openClineInNewTab: extract the unserialized creation body into createTabPanelUnlocked and guard the in-flight slot clear so a settled creation cannot clobber a replacement already stored in the slot. - onDidDispose: clear the tracked tab ref only when the disposing panel is still the tracked one, so a late disposal of a replaced panel cannot clobber the replacement's ref. - MDM lookup failure: log the fallback to the output channel instead of swallowing it silently. - Route the six title-bar button handlers through a shared postActions helper that posts each action in order and logs failures with the handler-specific prefix. - package.json: add the four InTab commands to the command palette, scoped to the active tab panel. - Tests: handler-level regression for openInNewTab + popoutButtonClicked started before the first creation resolves; fresh-creation test for a settled in-flight promise; stale-panel disposal regression; retained panel assertion for disposed tab instances; rightmost-editor column placement assertion; MDM fallback output assertion; %s placeholders for primitive it.each titles. - Stryker directives for the two equivalent setPanel type-literal mutants (setPanel branches only on type === sidebar).

Replace the weak toBeDefined() assertion in the dispose spec with an identity check against the panel returned during creation, per the CodeRabbit actionable comment on this PR (review run 7c4cfeb3-6dd9-4615- 9a58-70cfc705eca2). The tracked tab is now pinned with toBe(panel) before the dispose assertions, so a wrong or duplicated tracked panel fails the suite instead of passing a defined-only check. Upstream: Zoo-Code-Org#1528 (vps2 F0)

Retain the tracked tab panel in the InTab handler cases and assert that getInstanceForView was called with that exact panel, per the CodeRabbit actionable comment on this PR (review run 4afe1273-8739-4235-90d3-311db5f6ccb9, inline comment 3952466254 on the tabHandlerCases spec). A handler resolving any other view now fails instead of passing on the stubbed provider result alone; the same identity pin is applied to plusButtonClickedInTab. Upstream: Zoo-Code-Org#1528 (vps2 F0)

…States Each ClineProvider instance now owns a unique viewId (renderContext plus a monotonic counter) and registers a stable viewStateId for durable persistence. - Per-view state buffer (viewLocalState) holds mode / currentApiConfigName / apiConfiguration overrides in memory; saveViewState persists the non-secret subset durably under the active view id, rekeyed to the stable id on registration. - viewStates is stored as a map pruned to the newest 50 entries; writes go through a serialized queue so concurrent provider instances merge without lost updates. - setViewStateId sanitizes ids and rejects "__proto__" so a per-view entry can never be keyed through the Object.prototype setter. - postMessageToWebview no longer awaits the webview ack: a remounted or disposed page never acknowledges, and awaiting would wedge task-critical callers. - History restore falls back to the default mode view-locally instead of writing the shared global mode. - GlobalState gains the "viewStates" key and GLOBAL_STATE_KEYS tracks it. Adds F1a coverage in ClineProvider.spec.ts (viewId uniqueness, saveViewState persistence semantics, loadViewState fallback and failure, pruning, the __proto__ guard) and adapts the two history-restore tests in ClineProvider.sticky-mode.spec.ts to the view-local restore. getState() merging of hydrated per-view values and the remaining view-state suites land in the follow-up (F1b).

ClineProvider.resolveWebviewView registers its onDidDispose handler (the one that calls this.dispose()) only after its awaited getHtmlContent and getState calls. A rejection before that point left the provider in ClineProvider.activeInstances with its constructor-time resources alive, growing one orphaned provider per failed open: newPanel.dispose() ran only the registerCommands disposal handler. Dispose the provider explicitly in the failure path. The second dispose of the panel is a no-op, and a failing provider dispose is logged and swallowed so the original resolve error stays the one the command handler observes. Regression tests: the failure path now also asserts the provider dispose ran and that no active instance is left pointing at the failed panel, and a second test pins that a provider-dispose failure is logged while the original resolve error still propagates.

ClineProvider.dispose() marks _disposed before any cleanup runs, and the activeInstances release was the final cleanup step. A rejected cleanup step (task eviction, MCP/skills/marketplace teardown) left the provider retained in activeInstances with no retry path, so later resources stayed undisposed and the provider appeared as a ghost instance to getAllInstances()/getInstanceForView(). Wrap the cleanup body in a guard that preserves the first failure, run the release steps (activeInstances removal, listener cleanup, McpServerManager unregister) regardless of that failure, and rethrow the error after they have run so callers still observe it. Cover the release contract with a real-provider harness: ClineProvider.spec.ts now asserts getAllInstances() membership before and after dispose(), and that a rejecting cleanup step still releases the provider while surfacing the error to the caller. The command-level test in registerCommands.spec.ts keeps the disposal-call and error-precedence coverage; its getInstanceForView assertion is removed because the mocked resolver never assigns the panel to provider.view, making it vacuous.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

The dispose() restructure put the pre-existing cleanup body inside the unit delta, so the mutation gate now tests those lines. Cover the branches the default harness skips: - "runs every cleanup branch when the provider is fully wired": a task on the stack (eviction branch, proven through the task's own dispose()), a live view, registered webview/instance disposables, an initialized CloudService listener detach, and the exact cleanup log strings pinning the sequence. - "completes disposal when the optional manager instances are absent": nulls the manager instances the constructor normally initializes to prove the optional call sites skip cleanly instead of throwing. - The cleanup-failure test additionally asserts the exact reported message so the error template cannot be emptied. The CloudService instance getter is swapped with defineProperty (the style the getTelemetryProperties tests use) and the original descriptor is restored exactly; spying the mock's hasInstance is deliberately avoided because mockRestore leaves a cleared implementation that breaks the later telemetry tests.

The re-indented dispose() body put the `if (x)` guard of the disposables loop into the unit delta, and its conditional survived: a falsy entry pushed onto the disposables array must be skipped so disposal resolves instead of calling .dispose() on it and rejecting. Push one and assert disposal completes while the neighbouring real entry is still disposed.

Merge upstream/main and reconcile both sides: - registerCommands: keep the serialized openClineInNewTab flow on main's typed options + shared WebviewFocusTracker; spec calls pass the tracker. - ClineProvider: keep per-view mergedStateValues reads in getState (incl. main's new alwaysDenyUnapprovedCommands) and the non-await postMessage path with the original-content strip; port the view-identity review fixes (temporary-id authorship flag, ownsTargetEntry re-key gate, null-prototype viewStates, loadViewState ownership guard, setValue/setValues rollback). - dispose(): run every cleanup step independently (per-step try/catch, first error preserved and rethrown after all steps run; individual disposables isolated) so one failing step cannot leak the later releases (CR finding). New test: mcpHub.unregisterClient rejects and the later manager/store releases still run; existing cleanup-failure test updated for the per-step log. - api-set-configuration.spec: pass the required ClineProviderFactory argument. - tests: port sticky-mode view-state-keys suite, rollback tests, viewStates global-setting tests; re-key tests author entries via the write path. - eslint-suppressions: ClineProvider.spec.ts 196 -> 194.

…ting it The stable view state id arrives over the webview postMessage channel, so the declared string type is not a guarantee: a crafted message could carry a non-string value (which the sanitizer would crash on), an unbounded string (unbounded growth in the shared viewStates map), or an id another live view already owns (adopting it would load that view's pinned profile, overlay and mode here, and let this webview overwrite that view's persisted entry). setViewStateId now rejects non-strings, bounds the key length, and refuses ids claimed by another live instance; a refused view stays on its temporary id and keeps working against the shared state. The spec gains an afterEach that clears the static instance registry: the suite constructs providers directly and never disposes most of them, and a leaked instance would otherwise claim ids ahead of later tests. Proofs: ClineProvider.sticky-mode.spec 33/33 (3 new 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); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier ALL-MATCHED on touched files.

… view overlay as a complete profile Port of the review fixes landed on the get-state unit: 1. A save that does not activate (upsertProviderProfile with activate=false, and the zoo-gateway callback's non-active profile path) rewrote the profile's settings on disk but left every view pinned to it serving the pre-save snapshot from its buffer. The non-activating branch now refreshes pinned sibling views (and this view when it holds the pin), and the callback routes non-active profiles through upsertProviderProfile instead of a bare saveConfig so the refresh cannot be forgotten at that call site. 2. getState() spread the pinned overlay over the shared provider settings, so any key the pinned profile never defined leaked in from whatever profile the shared store points at (another profile's model id, region, tuning). The overlay is a complete profile snapshot: it is now used in place, with only apiProvider falling back to the shared state when the profile omits one. Proofs: ClineProvider.spec 294/294 (2 new tests: pinned-sibling refresh on non-activating save; no shared-key leak through the overlay; callback test updated to assert 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); sticky-mode 33/33, webviewMessageHandler 89/89; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier clean on touched files.

…tate The overlay-completeness fix 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: when a view had no overlay but the raw key held a partial object, getState() served only that partial object and dropped the shared provider settings the previous merge produced (activation tests caught exactly this: the activated profile's model id vanished). Read the overlay 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 (the six activation/upsert/ delete 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; prettier clean; tsc clean except the two known local telemetry-dist noise lines.

…aved A non-activating save refreshed the 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 sibling views, and the non-activating branch rebuilds this view's own handler when it holds the pin. Proofs: ClineProvider.spec 258/258 (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); sticky-mode 32/32, webviewMessageHandler 82/82; eslint --max-warnings=0 clean; prettier clean.

check deterministic, restore timers in finally Review round on this unit's test quality: the viewStates describe block was nested inside the alwaysDenyUnapprovedCommands block, so reported test names carried the wrong subject; the prune test asserted survival with toDefined(), which passes even if pruning strips fields - the surviving entries are fully known, so assert their exact shape (matching the parallel-mode suite); the stale-temporary-entry test waited on a fixed 10 ms timer, so a slow load could let the negative assertion pass vacuously - await the load itself; the readiness-cancel test left fake timers active when an assertion failed before the restore line, hanging a later real-timer test - restore in a finally block. Proofs: global-settings 9/9, ClineProvider.spec 294/294, sticky-mode 33/33, api-task-control 23/23; 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 clean.

viewWasPinnedToDeleted handling, including its setValue and view-local overlay
update. Keep the deletedWasGlobal path in the profile-deletion logic, updating
the shared selection and provider settings when survivingSettings is available.
- Around line 2950-2952: In rePinViewLocalStateForDeletedProfile, after updating
each sibling’s local state, rebuild its active task against replacementSettings
with forceRebuild enabled before posting state, so the task no longer retains
the deleted profile’s API configuration; also update the task’s persisted
profile name if needed to keep its history aligned with the replacement.

After applying the fix, consider running `coderabbit review --agent` for local

drop unreachable deletion branches, rebuild re-pinned siblings' tasks Review round on this unit: (1) when the view's durable mode pin write rejected inside handleModeSwitchUnlocked, 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 pin-write failure now restores the pre-switch task mode and history entry before rethrowing, so the switch is all-or-nothing for the delivered message. (2) The fallback deletion path re-checked whether this view pinned the deleted profile, but a view pinned to the deleted profile (or with no pin) takes the activation path above and returns - the re-check was unreachable; the dead branches are removed and the deleted-was-global handling kept. (3) rePinViewLocalStateForDeletedProfile updated each sibling'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: sticky-mode 34/34 (new pin-write-failure rollback test asserts the task mode and history entry are restored), parallel-mode 34/34 (the sibling re-pin test now asserts the active task's handler rebuild and sticky-name re-point), ClineProvider.spec 293/293 (dead-branch removal behavior- preserving); 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; prettier clean.

… task rebuilds Port of the sibling-unit fixes: handleModeSwitchUnlocked reconciles every write it owns (shared mode, view mode pin, task mode, task history) when a failure lands after the task-mode write, including the mode-linked profile activation, so submitUserMessage delivers on the pre-switch mode and profile. Non-activating profile saves only force-rebuild a view's task handler when the task actually runs under the saved profile. Regression tests for the activation-failure rollback and both rebuild guards. Test hygiene: prune assertions compare full kept entries; re-key storage tests seed through the durable write path so assertions can fail; sticky-mode afterEach disposes the per-test provider before resetting the instance registry; webview state-payload test renamed.

…wn profile Port of the sibling-unit fix: a view pinned to a deleted profile can hold a task that follows a different sticky profile: the deletion re-pin must re-point the view buffer but must not force the replacement's settings onto that conversation's handler, nor rewrite its persisted sticky profile name. Both task-side writes are now gated on a taskApiConfigName match with the deleted profile, mirroring the profile-save rebuild guards. Regression test included.

The mode-switch reconcile rolled the mode back even when the mode-linked activation had already written shared state (profile, provider settings, mode mapping, sticky task profile): a later failure then paired the old mode with the new profile, the very mismatch the reconcile exists to prevent. The catch now keeps the switch once activation has started writing, and also when the mutation signal has aborted - the queue has advanced past the timed-out switch, so a newer mutation may own the mode stores. The trailing state post moved outside the reconciled region: a UI-refresh failure after a fully committed switch is logged, not rolled back. Three regression tests included.
