Conversation
📝 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

- 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.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Keep a view-state write failure from aborting webviewDidLaunch.
setViewStateId assigns viewStateId before awaiting ContextProxy.setValue("viewStates", ...), which forwards the rejection from globalState.update. The message listener has no outer error boundary, so the callback can exit before the initial state, theme, API configuration, and isViewLaunched assignment run. Catch and log the failure, and restore the previous viewStateId so a later launch retries registration and loadViewState instead of returning early for the failed ID.

…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.
…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).
…tore deleteProviderProfile only rewrote the UI-facing listApiConfigMeta and currentApiConfigName in ContextProxy, leaving the profile's settings in the ProviderSettingsManager store (context.secrets). Per-mode mappings (modeApiConfigs) that still pointed at the deleted profile re-activated its stale settings on the next handleModeSwitch, clobbering the active configuration: the subtask child profile's gpt-4.1-mini leaked into ask-mode tasks, breaking downstream e2e suites (60s timeouts on search_files no-match and terminal reuse after zero-chunk shell race). Purge the profile from the store on delete so dangling mode mappings can no longer resolve it: listConfig().find(id) fails and handleModeSwitch continues with the current configuration. The F3 mode/profile isolation commit further up the chain introduces the same purge plus per-view pin handling. Regression test: sticky-profile spec "deleteProviderProfile removes the stored profile so a dangling mode mapping can no longer re-activate it".
handleModeSwitchUnlocked persisted the switched mode only through the deprecated updateGlobalState, so the in-memory viewLocalState buffer kept serving a stale restored mode: getValues() merges viewLocalState on top of the ContextProxy values and would shadow the fresh switch for consumers. Route the write through setValue so the buffer and the durable global state stay in sync, and cover it with a regression test for switching after a restored view state. Also assert the restored mode in public state, and harden the import viewStates test with a write-tracking proxy across all write paths (setValues/setValue/setProviderSettings) for seeded and fresh machines.
…isolate launch-suite provider doubles ProviderSettingsManager.deleteConfig now throws ProviderSettingsNotFoundError for a missing config and rethrows it unwrapped, so ClineProvider.deleteProviderProfile branches on the type instead of matching the not-found message text that a profile name could spoof; the sticky-mode handleModeSwitch test additionally pins the durable per-view persisted mode and getValues(); the webviewDidLaunch tests restore the mockClineProvider members they replace after each test so launch stubs cannot leak.
… state WMH webviewDidLaunch persists the webview view-state id via provider.setViewStateId and re-pins the view-local currentApiConfigName through provider.saveViewState when the view-local profile is missing but the shared global selection is still valid. updateSettings is routed through provider.setValue so view-local buffer and pin sync stay consistent with the other mutation paths. The webview VSCodeAPIWrapper gains a stable getViewStateId persisted via setState (with an in-memory fallback) and the launch effect posts the id with the webviewDidLaunch message.
…ate ids getViewStateId now trims and rewrites unsafe characters before reuse, mirroring ClineProvider.setViewStateId, and rejects whitespace-only and __proto__ values by generating a fresh id. Regression coverage: normalized reuse, whitespace-only, and __proto__.
…d profile has no name The launch-time re-pin guard required the first listed profile to carry a name, so with a legacy nameless profile the still-valid shared global selection fell into the repair branch and was cleared with undefined for every view. Drop the name requirement: the view-local re-pin only needs the shared selection to resolve. Cover the combination (valid global selection + nameless first listed profile) and assert the shared selection is never written as undefined. Also pin the exact fixture values for the getState merging case instead of toBeDefined.

The restore runs in the wrong suite, so the launch doubles leak into every test between them.
The webviewDidLaunch suite at Line 275 reassigns providerSettingsManager, getMcpHub, and getStateToPostToWebview on the shared mockClineProvider in its beforeEach, and never restores them. The afterEach that restores the snapshot is scoped to the telemetrySetting describe, so it first runs long after the launch suite finishes. Vitest executes suites in file order, so every test declared between the two suites — including the updateSettings tests — observes the launch doubles instead of the module-level mocks.
Put the restore in the launch suite's own afterEach and keep the snapshot at module scope.
🧪 Proposed fix
Move the snapshot to module scope (next to mockClineProvider) and restore inside the launch suite:
const double = mockClineProvider as unknown as LaunchProviderFixture
+ afterEach(() => {
+ const view = mockClineProvider as unknown as {
+ getMcpHub: unknown
+ providerSettingsManager: unknown
+ getStateToPostToWebview: unknown
+ }
+ view.getMcpHub = launchSuiteSnapshot.getMcpHub
+ view.providerSettingsManager = launchSuiteSnapshot.providerSettingsManager
+ view.getStateToPostToWebview = launchSuiteSnapshot.getStateToPostToWebview
+ })

Capture the deleting view’s local pin before updating it.
When the local pin names the deleted profile but the global selection differs, setValue("currentApiConfigName", profileToActivate) updates the local pin before the guard runs. The guard then skips the deleting view, and rePinViewLocalStateForDeletedProfile excludes it. getState() keeps the local apiConfiguration, so it reports the surviving profile name with the deleted profile’s provider settings.
Capture the pin before setValue, then include the captured value in the guard. Keep setProviderSettings conditional on the global selection.

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
