|---|---|
View-state contracts and identifier persistence packages/types/src/*, webview-ui/src/context/*, webview-ui/src/utils/* |
Schemas define persisted viewStates and optional viewStateId values. VSCodeAPIWrapper creates stable identifiers and uses in-memory state when browser storage is unavailable. |
Provider-local state persistence and isolation src/core/webview/ClineProvider.ts, src/core/webview/__tests__/*, src/core/config/ProviderSettingsManager.ts, src/core/config/__tests__/ProviderSettingsManager.spec.ts |
ClineProvider loads and persists view-local mode and profile selections, merges them over shared values, and clears the current view state on reset. Profile changes synchronize affected views. Missing configurations use a typed error. |
Launch and settings synchronization src/core/webview/webviewMessageHandler.ts, src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/*, src/core/webview/__tests__/webviewMessageHandler.spec.ts |
Launch handling registers the view identifier and validates its API profile selection. Settings import and export omit viewStates. Settings updates use provider-level methods. |
Sidebar and editor-tab command routing src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts, src/package.json, packages/types/src/vscode.ts, src/eslint-suppressions.json |
New editor-tab commands target the provider for the tracked panel. Sidebar commands target the activation provider. Live tab panels are reused, and overlapping panel creation requests share one in-flight operation. |

Merge Risk: 🟡 Moderate · up to 85543
A view can lose its saved selection when it launches with certain IDs, and leaked test doubles weaken launch-related checks. Fix those paths before merging.
Security Architecture Review
Security architecture risk: 🔵 Low · up to 85543
Per-view isolation and tab targeting have safeguards, but two state-identity and configuration-refresh cases can leave a view using a selection or configuration different from the one expected. The evidence does not establish a remote attack path.
Retained concerns
- Low · security · inferred: Settings import updates shared provider profiles without refreshing already-loaded view-local API configuration buffers. A pinned view can continue presenting its pre-import configuration under a profile name whose stored settings have changed; any effect on subsequent task requests needs confirmation.
- Low · reliability · inferred: A stable view ID of “constructor” passes validation, but re-keying checks an ordinary object's inherited property as though it were an existing stable entry. It can discard this view's temporary persisted selection and leave the view to load a different or shared selection.
Security review details
Security Blast Radius
- inferred — The demonstrated scope is local to extension-managed views and their shared profile store. A stale buffered configuration can affect a pinned view after import; the evidence does not establish cross-user access or a remotely reachable entry point.
Security Findings and Attack Paths
- inferred — After a user imports changed settings for an existing profile, a previously loaded view can continue exposing its old buffered API configuration because import changes the shared store but refreshes only the invoking provider's posted state. Whether that stale configuration reaches a later external task request remains unverified.
Trust Boundaries and Controls
- observed — The extension normalizes webview-supplied IDs and rejects empty and “proto” IDs. It does not reject every inherited object-key name or establish unique ownership of a normalized ID.
Resilience and Maintainability Implications
- observed — Failure to persist registration no longer prevents initial state posting, and the former ID is restored for a possible later attempt. No retry on the same mounted launch was established.
Hardening Proposals
- proposed — Refresh or invalidate loaded per-view profile configurations when settings import changes profiles, and use own-key checks for stable-ID map operations. Treat an ID collision as a state-ownership case rather than proof that two views are the same owner.

Full details: Regression Evidence
Explanation
The launch identity change lacks composed-runtime coverage and introduces a duplicate launch path. ExtensionStateContextProvider now posts webviewDidLaunch with viewStateId (webview-ui/src/context/ExtensionStateContext.tsx:519), while the unchanged App still posts webviewDidLaunch separately (webview-ui/src/App.tsx:207). AppWithProviders mounts both components. The new tests render ExtensionStateContextProvider alone, and App.spec.tsx replaces that provider with a pass-through mock, so no test checks the actual launch count or ordering.
Resolution
Centralize webviewDidLaunch in one component. Remove the redundant App launch effect, or move the stable-ID payload into the existing App effect. Add an App-level test with the real ExtensionStateContextProvider that asserts one launch message with the stable ID and covers the unavailable-helper fallback.
Full details: Persistence Integrity
Explanation
The changed ClineProvider.setValue path is not atomic. It first persists the shared key through contextProxy.setValue, then persists the per-view subset through _saveViewLocalStateFromMutation and savePersistedViewState. If the second viewStates write fails, the shared write remains, while the view-local buffer is not updated. For example, an updateSettings mode or profile update can change the shared selection, then fail on the per-view write; a reload can expose that shared selection to other views. handleModeSwitch has a specific rollback, but generic setValue, setValues, and the updateSettings path have no rollback or explicit partial-failure handling.
Resolution
Make shared and per-view persistence transactional, or define and implement rollback. Capture the previous shared value and restore it when _saveViewLocalStateFromMutation fails, including the multi-key setValues and profile-activation paths. Alternatively, use one serialized persistence operation that commits both representations and reports a consistent failure state. Add tests that force the viewStates write to reject after the shared write and verify that neither the shared selection nor the view-local selection is left partially updated.
Full details: Lifecycle Resource Cleanup
Explanation
The new cross-view profile synchronization can perform work on a disposed provider. refreshViewLocalStateForUpdatedProfile() and rePinViewLocalStateForDeletedProfile() iterate over ClineProvider.getAllInstances() and only exclude this; they do not exclude providers whose dispose() has already set _disposed. dispose() removes the provider from activeInstances only after awaited cleanup. If provider A changes or deletes a profile while provider B is disposing, A can call B's _saveViewLocalStateFromMutation() and persist B's view state after disposal. This is duplicate lifecycle work and can recreate stale durable state for the closed view.
Resolution
Exclude disposed providers from cross-view synchronization, preferably through a live-provider predicate such as !instance._disposed (or a public disposal state). Re-check the disposal state immediately before each asynchronous mutation and post, because disposal can begin after the initial instance snapshot. Add a regression test that starts provider disposal, triggers profile activation or deletion from another provider, and verifies that the disposing provider receives no state mutation or durable view-state write.

Inline comments:
In `@src/activate/__tests__/registerCommands.spec.ts`:
- Around line 519-520: Extend the declared type of mockProvider to include
evictCurrentTask and refreshWorkspace, then assign those typed mocks directly
without explicit any assertions. Keep the existing mock behavior unchanged.
In `@src/activate/registerCommands.ts`:
- Around line 288-295: Update the tab panel disposal handling near the
existingProvider branch so the stale panel’s onDidDispose callback clears the
tracked panel only if that disposed panel is still the current tracked panel.
Preserve the replacement panel reference when a new panel has already been
created, and add a regression test covering stale-panel disposal after
replacement creation.
In `@src/core/webview/__tests__/ClineProvider.sticky-profile.spec.ts`:
- Around line 1056-1058: Update the getProfile assertion for
"subtask-child-profile" in the sticky-profile test to verify the specific
missing-profile error, while retaining the existing rejection assertion and
authoritative-store deletion check.
In `@src/core/webview/ClineProvider.ts`:
- Around line 2219-2222: Update the profile-deletion flow around
ProviderSettingsManager.deleteConfig and getProviderProfileEntries so a
missing-profile deletion removes the stale listApiConfigMeta entry while
preserving the invariant that the final configuration cannot be deleted. Derive
the deletion guard and list update from ProviderSettingsManager where possible,
handle the not-found rejection without masking other errors, and add tests
covering both divergent-store cases.
In `@src/core/webview/webviewMessageHandler.ts`:
- Line 583: Update the webviewDidLaunch flow around provider.setViewStateId to
catch and log persistence failures without aborting subsequent initial-state,
theme, API configuration, and launch-state setup. Restore the previous
viewStateId when the write fails so a later launch retries registration and
loadViewState instead of treating the failed ID as already handled.
In `@webview-ui/src/utils/vscode.ts`:
- Line 93: Update the state retrieval flow around getViewStateId so a failed
setItem write marks or preserves the in-memory fallbackState, and subsequent
calls return that state instead of stale persisted JSON. Keep normal
persisted-state behavior when writes succeed, and add a regression test covering
readable storage whose setItem throws.

…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).
…lude viewStates from settings transfer
…ions through the view-local buffer
…nd target tab-instance commands Reapply in-flight view-local fields with Object.is identity so a field cleared during the load window stays cleared; route mode switches through setValue so the in-memory buffer and durable write agree, with rollback on failure; refresh cross-instance view-local state on profile upsert, activate and delete and re-pin the buffer after a delete; point focusInput and active-panel re-registration at the tracked tab provider and panel; log dropped webview postMessage failures with the message type; pin tab-instance, focusInput and active-panel identity in the registerCommands tests and type the mdm double in the provider spec.
…apture view pin on delete Address CodeRabbit walkthrough findings on the F1a unit: - handleModeSwitchUnlocked now bails before the task-level writes when the abort signal has fired, closing the partial-apply window where a cancelled switch could still rewrite the persisted task mode; the existing pre-write guard still covers in-flight aborts. - Replace bracket access to sibling-instance private members with a typed pinnedProfileName getter and direct private member access (compile-time safe across instances). - deleteProviderProfile now captures this view's pin before the currentApiConfigName rewrite so a view pinned to the deleted profile while the global selection points elsewhere is still reconfigured with the surviving profile's settings. Tests: focusInput asserts the tab panel by identity and that no error was logged on the success path; the stalled getProfile double fails loudly on a second lookup (only one lookup is resolvable).
…-local profile pins
handleModeSwitchUnlocked: an abort landing while updateTaskHistory is in flight previously left the new mode persisted in task history and assigned to task._taskMode before the pre-write signal check bailed; the landed write is now rolled back to the pre-switch item and the method returns before the TaskModeSwitched emit and the durable mode write. TaskModeSwitched now only fires for a completed transition. deleteProviderProfile: the unconditional setValue('currentApiConfigName', ...) overwrote a view's pin when an unrelated profile was deleted; the pin is now re-pointed only when it names the deleted profile, and a deleted-was-global deletion updates the shared store only. The nested apiConfiguration overlay is replaced with the surviving profile's settings only for a view pinned to the deleted profile.
…tore deleteProviderProfile pruned the UI-facing listApiConfigMeta entry but never removed the profile's settings from the ProviderSettingsManager store (context.secrets), so a later listApiConfigMeta sync could resurrect the deleted profile and a dangling per-mode mapping could re-activate it. The purge now calls providerSettingsManager.deleteConfig and branches on the typed ProviderSettingsNotFoundError (introduced here alongside) so an already-gone secret is an idempotent success -- the stale list entry is still pruned -- while any other failure (e.g. the store refusing to delete the last remaining configuration) propagates. Matching message text instead would let a profile whose name contains 'not found' swallow an unrelated failure. Tests: the dangling-mode-mapping resurrection scenario, the already-gone secret, the store-level last-profile refusal, the typed-signal contract in the manager spec, and provider-level not-found/propagation pins.
A failed task-history rollback during an aborted mode switch previously propagated into the outer persistence-error handler and surfaced as the switch's own persistence failure. Guard the rollback with its own try/catch so the rollback error is logged with task context and the cancellation return is preserved (CodeRabbit finding on this PR).
…d switch The in-flight abort rollback rewrote the whole task-history item with the pre-switch snapshot, clobbering any fields the running task persisted during the pending window (tokens, cost, status, apiConfigName). Re-read the item and restore only the mode this switch changed (CodeRabbit data-integrity finding on this PR).
Rebasing onto main tip merged main's createTabPanelUnlocked body with the PR's serialized creation. Main no longer resolves CodeIndexManager in this function, so the leftover line referenced an import the PR never added and the suite failed with ReferenceError. Removing it restores the PR's own delta: 48 registerCommands tests and 459 F1a tests pass.
…overrides Fold ClineProvider viewLocalState on top of ContextProxy values in getState() (mode, apiConfiguration, and all per-view fields) so each webview reports its own selections while falling back to shared global state for everything else. Ports the getState-merging and local-state-isolation spec coverage from the superseded vps2 source. Also pins the full default surface of the merged read path, including the apiConfiguration provider fill-in when provider settings sanitize the raw value away (mutation-diff gate).
Rebuilding the F1b unit as main tip + its own delta cleared the conflict with main. The patch was authored against an older main, so applying it dropped the alwaysDenyUnapprovedCommands entry from getState(); restoring it with the shared default constant keeps the settings round trip complete. 410 tests pass.
Applying the F1c delta (ad94239...8554307) onto the rebuilt F1b head cleared the conflict with main tip without changing content. 338 src tests and 39 webview-ui tests pass.

Issue (created at PR-open time): #1551
What
Persists each webview's stable state identity at launch and makes launch-time per-view state re-pin correctly. The webview now carries a
viewStateId(created and persisted via the webview state API, with an in-memory fallback) that is posted withwebviewDidLaunchand persisted on the provider viasetViewStateId, re-keying the pre-launch temporary state entry to the launching webview. When the view-local API profile is invalid at launch, the view is re-pinned to the still-valid shared global selection with a view-local write only — the shared global is repaired only when its own selection is also invalid.updateSettingsis routed throughprovider.setValueso view-local buffer/pin sync stays consistent with the other mutation paths.Design decisions
VSCodeAPIWrapper.getViewStateId): it reuses the id persisted in webview state, creates one (crypto.randomUUID, with a timestamp+random fallback) and persists it viasetState; when storage is unavailable it falls back to an in-memory field. The id is best-effort — the launch message carriesviewStateId: undefinedwhen the helper is unavailable, and the provider degrades to the shared-global path.provider.saveViewState("currentApiConfigName", name)writes the view's buffer/pin without touching the shared global selection; the legacy global repair (global write +activateProviderProfile) runs only when the shared global selection is also invalid.getState()semantics from F1b.updateSettingsdelegates toprovider.setValuerather thancontextProxy.setValueso the view-local buffer/pin sync path (_saveViewLocalStateFromMutation) runs for settings edits too.Measurements
