📝 SummarySummary by CodeRabbit
WalkthroughThe change adds stable webview identifiers, persistent non-secret per-view state, provider-level state isolation, launch-time synchronization, and separate sidebar/editor-tab command routing. It also adds coverage for persistence, recovery, command targeting, panel reuse, and storage fallbacks. ChangesMulti-view state and command routing

Full details: Regression EvidenceExplanation The PR adds sibling-view synchronization without focused coverage for the affected branch. Resolution Add focused Full details: Persistence IntegrityExplanation A changed mutation path has an unhandled partial-write case. Resolution Use one mutation helper for shared and per-view settings. Capture the previous shared value, previous view-local value, and previous persisted view-state entry before writing. If either write fails, compensate by restoring the other store and the in-memory buffer, then report the failure. Update Full details: Lifecycle Resource CleanupExplanation Changed cross-view profile refresh can run after a sidebar view is disposed. Resolution Track sidebar view detachment explicitly and exclude detached providers from cross-view refresh and re-pin operations. Clear or invalidate the provider's ✨ Finishing Touches 💡 1🛠️ Fix failing CI checks 💡

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.

Same stacked-series effect as #1550: this PR's own layer is ~72 a+d; the excess comes from the layers below it in the stack (notably #1546 f1a at ~900 a+d). Once #1546 lands on main, this PR's delta falls under the 500-line cap and the gate will pass on the next main merge. No code change is expected from this PR. |

2381-2387: Refresh the deleting view’s local API configuration.This duplicates the existing review finding. If this view is pinned to the deleted profile while the shared selection names another profile, this condition is false.
setValue()changes only the local profile name, and this instance is excluded fromrePinViewLocalStateForDeletedProfile(). The local API configuration then remains for the deleted profile.
4105-4108: 🎯 Functional Correctness
createTaskspreadsoptionsintonew Task, sohandoffExecutionContextreaches the constructor.Taskthen useshandoffExecutionContext.apiConfigurationin preference to the fallbackapiConfiguration. The selected handoff configuration therefore reaches the task, and passingeffectiveApiConfigurationseparately is unnecessary.
…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).

- Line 2400: Update deleteProviderProfile so setValue("currentApiConfigName",
profileToActivate) does not overwrite an unrelated view-local profile pin; only
replace the local value when it matches the profile being deleted. Adjust the
associated test expectation to preserve keeper-profile.
- Around line 2086-2088: Make the mode-switch flow in ClineProvider
cancellation-safe across the pending updateTaskHistory() operation: recheck
cancellation before committing task history or _taskMode, and ensure an aborted
or partially failed transition leaves no partial mode state before the queue
advances. Add deterministic coverage in the sticky-mode tests by aborting while
controlled updateTaskHistory() is pending and asserting that neither transition
state nor persisted mode state remains.
- Line 2412: Update the deletion flow around viewWasPinnedToDeleted to persist {
apiConfiguration: survivingSettings } through _saveViewLocalStateFromMutation
when the deleted profile is pinned locally; leave views pinned to another
profile unchanged. Extend the relevant tests to seed the deleted nested
apiConfiguration and verify it is replaced, while a different local pin remains
intact.

…l buffer Flat provider-settings writes now flow through the ContextProxy only; merging them into viewLocalState.apiConfiguration turned them into a per-view override that masked later shared updates from other views (the e2e provider-probe suites: 14 failures). Ported from dfcc3e7 of the f1c-webview-identity unit; adds a regression test pinning the profile-activation -> global-write -> getState ordering and retargets the tests that pinned the removed merge behavior.

…-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.
# Conflicts: # src/core/webview/__tests__/ClineProvider.spec.ts
…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.

Part of the vps2 durable per-view state series — tracked in easonLiangWorldedtech#41 (cross-repo: standalone a+d measured against the stack base; the displayed vs-main diff includes lower units until they merge).
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
