Exciting to see this work come together! Had some implementation comments, and can we also add some ui testing:
We can leverage the UI testing setup established in McpServerRestriction.spec.tsx and webview-ui/src/utils/test-utils.tsx:
-
ExtensionStateContext.ProviderWrapper Pattern:
Re-use therenderWithStatepattern to mount webview components with specificviewStateIdprops and verify that UI components respond correctly to view-localmodeandcurrentApiConfigNamestate without global bleed. -
Reseed & Identity Tests:
Similar to the slug-change reseed tests inMcpServerRestriction.spec.tsx, add UI-level tests inExtensionStateContext.spec.tsxorApp.spec.tsxto verify that whenviewStateIdchanges or a webview reloads, local React state reseeds properly from the new view'sviewStateIdpayload. -
vscode.getViewStateId& Messaging Spies:
Ensure UI tests verifyVSCodeAPIWrapper.getViewStateId()fallback behavior whensessionStorage/localStorageare restricted or cleared.

…iable - removeRegisteredTask only drops the registration when the stored controller is the same instance, so a replaced task reusing a taskId is not torn down by the old instance's abort/unfocus events. - selectTaskFollowupSuggestion delivers the answer even when the follow-up mode switch fails, logging the failure instead of losing the user's response.
…selection - webviewDidLaunch rescue: when the view's own pin is invalid, re-pin the view to the shared global selection if it is still valid instead of overwriting the global setting and activating a global profile from one view's launch path. - updateSettings persists provider settings through the provider-level setValue so the durable write path is the one the provider serializes. - Lower the recorded no-explicit-any suppression counts for the touched files (fixes, not new suppressions).
…red fixtures - view-state.test.ts derives the round count from the follow-up isolation fixture instead of a hardcoded 10, and drops an unused map. - Document the new mode-switch predicate fixtures alongside the legacy model-scoped fixtures in runTest.ts.
- The webviewDidLaunch describe now assigns its runtime members through a structural LaunchProviderFixture cast instead of per-line as-any, and the getState mock return is typed against the provider signature. - Drops the webviewMessageHandler.spec.ts suppression count back to the PR base level (35).
…ion spec Use typed structural casts (ClineProvider / OutputChannel) for the API double and remove the now-empty suppression entry for the file.
CI e2e-mock regression: the mode switch inside a task lands before the tab webview's launch message registers its stable viewStateId, so the ephemeral-skip silently dropped the view's durable mode write and the "sidebar and tab panel keep mode isolated" e2e timed out waiting for the persisted entries. Pre-launch writes now persist under the temporary view id and are re-keyed to the stable id when the webview registers it (setViewStateId runs the re-key through the serialized write queue before loadViewState). A pre-existing stable entry wins and the temporary entry is dropped, since temporary ids are session counters that can collide across window reloads. The stale-load guard is unchanged. Unit tests: the ephemeral-skip assertion is replaced with re-key tests (write under temporary id, re-key on registration, stable entry wins) and the stale-load test is restructured so it genuinely exercises the guard through the cached read path.
…elMode spec Address the CodeRabbit maintainability finding: drop the blanket no-explicit-any suppression (137) for ClineProvider.parallelMode.spec.ts and type the spec properly instead. - Private member access moves from (provider as any).x to bracket notation (provider["x"]); public members (saveViewState, setValue, setValues, handleModeSwitch, resolveWebviewView, log) drop the cast entirely and keep their native generics. - MockContextProxy now takes vscode.ExtensionContext; memento and mock callbacks use unknown instead of any; the webview structural double is cast once as unknown as vscode.WebviewView. - Key/value casts are removed where the key is a valid RooCodeSettings key; the one genuine exception (apiConfiguration is a GlobalState key outside the proxy's generic) keeps a documented double assertion. - api-configuration.spec.ts: document the as-unknown-as-ClineProvider structural double in the new test (API.getConfiguration only reads sidebarProvider.getValues). check-types clean; parallelMode 49/49 and api-configuration 3/3 green; eslint --prune-suppressions clean with the parallelMode entry removed from eslint-suppressions.json and every other count unchanged.
Review of every mode-change entry point surfaced three inconsistencies:
- handleModeSwitch accepted any slug (the webview "mode" message sends
message.text as Mode with no server-side validation), so unvalidated
callers could persist invalid modes into task history and the view's
durable pin. Validate the slug against built-in + custom modes and
no-op (with a log) on unknown slugs, mirroring
selectTaskFollowupSuggestion.
- Task.submitUserMessage wrote the mode through setValues (raw global
ContextProxy write, no history entry, no TaskModeSwitched/ModeChanged,
no view pin) while every other switch goes through handleModeSwitch.
Route it through handleModeSwitch(mode, this) so an API-initiated
switch is recorded like any other.
- delegateParentAndOpenChild passed the child's mode as as any; drop the
cast now that handleModeSwitch validates.
Test updates:
- sticky-mode: the "invalid mode" test now asserts the ignore behavior;
the module-level getModeBySlug mock's undefined override (leaked past
vi.clearAllMocks, which does not clear implementations) is restored in
the top-level beforeEach so later tests validate through the default;
the slow-init ordering test settles the restore's early durable write
before issuing the mid-init switch, matching the production order in
which a user's switch is issued after the restore starts.
- Task.spec: the submitUserMessage mode test now expects
handleModeSwitch("code", task); the mock provider gains the method.
check-types clean; 336/336 across the six affected spec files; eslint
--prune-suppressions clean (ClineProvider.ts no-explicit-any 12 -> 11).
The "sidebar and tab panel keep mode isolated" e2e test timed out on its 15s viewStates poll at 30c4f0c while 85 other tests passed and the previous head (f91e19c) was green. Log the serialized viewStates write queue outcomes (write/clear/rekey) and snapshot the raw globalState read at the start and timeout of the poll so the next CI run pinpoints where the ask/debug entries go missing. Revert this commit once the cause is found.
The 15s viewStates poll timed out once at 30c4f0c while 85 other e2e tests passed; the same code with diagnostics (16c6c64) ran green, confirming a timing flake rather than a regression. The DIAG logs showed the serialized write queue produced the correct ask/debug entries. Remove the temporary write/clear/rekey and read logging from ClineProvider (back to the 30c4f0c content) and the test, and raise the poll budget from 15s to 30s to match the suite's other waits (waitUntilCompleted, follow-up polling) so a slow memento flush under CI load cannot turn a correct write into a failure.
Restore api-task-control.spec.ts (2-arg handleModeSwitch expectations), api-configuration.spec.ts (providerIdentifiers import), and webviewMessageHandler.spec.ts (single telemetry mock block) from pre-rebase head bac74f1; the rebase re-edit conflict resolutions had downgraded them.
…derer ack postMessageToWebview awaited the webview postMessage promise, which VS Code only settles once the webview page acknowledges the message. When the page is remounted or reloaded, or the view is disposed while the post is in flight, that promise is orphaned forever and every caller awaiting it wedges on the task critical path. This wedged the tab task in the e2e view-state test: switch_mode awaited handleModeSwitch, whose trailing postStateToWebview was blocked on the orphaned ack during a webview remount, so the task's next turn never started and the 30s waitUntilCompleted timed out. Dispatch the post without awaiting the ack (with a rejection catch). Message ordering is enforced by the message seq, not by the ack. Add a unit regression test asserting postMessageToWebview returns without waiting for the renderer ack.
Scope the mode-switch handler to the target task (SwitchModeTool, Task, extension api) so the slug is validated and an unknown slug leaves the task mode untouched instead of recording a bad one. On webviewDidLaunch, re-pin the view to the still-valid shared global profile rather than the first listed profile; add a regression test. Convert the remaining as-any casts in the sticky-mode and parallelMode specs to bracket notation / typed doubles; add a deterministic view-state id fallback test; surface follow-up delivery failures in the e2e view-state diagnostics. Reduce the sticky-mode no-explicit-any suppression count to match the cleanup.
The CodeRabbit fixes moved the task-mode write into ClineProvider.handleModeSwitch (after validation and persistence) and made SwitchModeTool pass the explicit task. Update the pre-existing specs accordingly: - switchModeTool.spec.ts: handleModeSwitch is now asserted with (slug, task) - Task.spec.ts: the handleModeSwitch mock mirrors the provider's post-persistence mode write, and the test settles the task's initial mode before the user-selected mode switch
Run 33651477142 (head beb70ac): extension-host-visual failed only in repeat 1 of electron-chat-dark-sidebar (354 px, ratio 0.01); repeat 2 passed with the same code on the same runner. Pixel forensics on the 300x743 sidebar (webview bg lum ~49) shows the diff in exactly three zones, all consistent with the webview lagging the completion_result event (screenshot taken ~790 ms after it landed): - TaskHeader context row: actual shows the CircularProgress arc with a non-zero percentage plus cost text; the baseline (settled) shows 0%, only the 0.2-opacity ring background, and no cost. - Send button: identical glyph shape, only the streaming background class differs (max lum 92 vs 103). - Input placeholder: actual "Type a message..." vs settled "Type your task here...". The scene resolves on the completion_result message event while the webview streaming/cost/placeholder state settles slightly later, and no task-idle signal exists in the API surface to wait on. Earlier branch heads (5383cd9, bc34ecc, 02b5ea8) were fully green including extension-host-visual. Empty commit to re-trigger CI; no code change.
CI failures on this PR — both triaged as flakes, re-triggeredTwo unrelated one-off failures have occurred on recent heads; both are settled-state evidence, not regressions: 1. 2.

No task-idle signal exists in the API surface to wait on, and the settled baseline is the correct target state, so no test change was made — that would risk changing which state the baseline represents. Precedent: earlier branch heads Re-triggered with empty commit |

- Around line 180-184: Update the voided promise chain in the follow-up
suggestion delivery flow to add a rejection handler for
selectTaskFollowupSuggestion. Record the task identifier and rejection details
in deliveryFailures so the eventual timeout diagnostic names failed deliveries,
while preserving the existing handling for fulfilled results where delivered is
false.
In `@src/core/task/Task.ts`:
- Line 1665: Update the mode-switch flow around handleModeSwitch so a rejection
is caught and logged locally, allowing execution to continue to
handleWebviewAskResponse and deliver the pending ask. Add a regression test at
the lowest valid test layer that makes handleModeSwitch reject and verifies the
ask response is still set.
In `@src/core/tools/SwitchModeTool.ts`:
- Line 60: Update SwitchModeTool’s early-return comparison and success message
to use await task.getTaskMode() for the executing task rather than the focused
provider mode, while preserving the mode-switch call on task. Add a regression
test covering different focused-task and executing-task modes to verify the
executing task switches independently.

- Around line 715-721: Update the viewStateId handling to sanitize the trimmed
value before comparing it with this.viewStateId, then return early when the
sanitized value is empty or unchanged. Store and compare the same sanitized

- Around line 2265-2280: In the profile-deletion flow, resolve the replacement
profile identified by profileToActivate and apply it through the existing
activation path rather than only updating the profile name. Ensure activation
refreshes viewLocalState.apiConfiguration and invokes

repointing behavior.
- Around line 3531-3560: Update setValues to validate any provided mode with
getModeBySlug(mode, await this.customModesManager.getCustomModes()) before

Timestamp: 2026-07-30T20:04:07.669Z
Learning: For `src/core/webview/ClineProvider.ts`, VS Code `onDidDispose` does not reliably distinguish an explicit user tab close from reload, shutdown, or extension deactivation. Do not use generic provider disposal as the signal to delete durable per-view `viewStates`; explicit close intent is required.

The theme class swap in applyVisualTheme started ~150ms color transitions (transition-colors) and the contrast asserts plus screenshot baselines sampled mid-transition colors on CI. Apply a .visual-theme-applying class for one style flush with transition-duration forced to 0ms so assertions observe the final theme values.
…t guards Add five tests killing the seven surviving changed-code mutants: crypto global undefined (timestamp fallback id), stored state parsing to JSON null, non-object persisted state replacement, empty persisted viewStateId replacement, and the launch effect when getViewStateId is unavailable. Exclude the two equivalent localStorage guard mutants (guard-false and body-throw paths both return the same value through the surrounding try/catch).

Description
Add the foundational per-view state infrastructure for parallel mode. This is the root PR that all subsequent parallel-mode PRs depend on.
How:
webview-ui/src/utils/vscode.tsviagetViewStateId(), sent during launch).ClineProvider.setViewStateId()sanitizes it into a safe object key.viewLocalStatebuffer: transient per-view state that merges on top of the sharedContextProxyvalues ingetState()(themergedStateValueslayer), so a tab's mode never overwrites the sidebar's.viewStatespersistence: registered global setting key storing only non-secret selections (mode,currentApiConfigName,updatedAt), bounded to the most recent 50 entries byupdatedAtordering.viewStatesmutation goes through a static write queue (persistedViewStateWriteQueue) that re-reads the map fresh fromglobalStateon each write, so concurrent sidebar/tab providers cannot clobber each other.Reviewers should pay attention to:
mode,currentApiConfigName). FullapiConfiguration(API keys, Kimi Code keys) is never written to globalState; e2e asserts no secret paths leak into persisted entries.viewStatesentries. Retention uses the 50-entry pruning cap. Follow-up#1065tracks explicit stale-entry cleanup.approveTaskAsk,selectTaskFollowupSuggestion) andpreserveOpenTabsfor new tasks. These are required so parallel views can be driven per-task by the orchestrator e2e foundation (test(vscode-e2e): add orchestrator E2E foundation for parallel-mode coverage #1064), which is why they stay in this root PR rather than being split out.Test Procedure
