📝 SummarySummary by CodeRabbit
WalkthroughThe change adds stable per-webview identifiers, persistent non-secret view state, provider-level state isolation, view-aware launch 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.

Do not require name to take the view-only re-pin branch.
The re-pin branch uses globalConfigName, not name. The guard still requires name, so a legacy listApiConfig[0] without a name sends control to the else branch even when the shared global selection is valid. That branch then runs updateGlobalState("currentApiConfigName", name) with name === undefined, which clears a valid shared selection for every view and skips activation. This contradicts the stated intent that the global selection is repaired only when it is invalid.
Drop name from the condition. The else branch already handles the nameless case.
🐛 Proposed fix
- if (globalStillValid && globalConfigName && name) {
+ if (globalStillValid && globalConfigName) {Add a test for a valid shared global selection combined with a first listed profile that has no name, and assert contextProxy.setValue is not called with undefined.

branch guard around globalStillValid and globalConfigName to remove the name
requirement, allowing valid shared selections to use globalConfigName even when

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.

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
…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".
… 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__.

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
