feat(webview): setValues batch persistence and reset cleanup (N4, split 4/5 of #1546) - #2236
Split unit N2 of Zoo-Code-Org#1546: viewStates read/write queue, claim rekey, prune, clear, load/save and export/import sanitization on top of N1 identity. Buffer/mutation/history content remains for N3.
N2 spec now includes the N1 identity tests plus the persistence/load/prune/rekey/export-import coverage; the setValues buffer test moves to the buffer unit.

📝 Summary
Summary by CodeRabbit
New Features
Mode, provider profile, and API configuration selections are now maintained separately for each open view.
View-specific selections are saved and restored across sessions.
Bug Fixes
Exported and imported settings no longer include view-specific selections.
Deleting a provider configuration that doesn’t exist now reports a specific error.
The change adds claim-bound per-view state for mode and provider selections, excludes that state from settings import and export, adds a typed error for deleting a missing provider configuration, and checks for Git LFS in four hooks.
Changes: Per-view state
Layer / File(s)
Summary
Per-view state contracts and settings boundaries packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, packages/types/src/__tests__/*, src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/ContextProxy.spec.ts, src/core/config/__tests__/importExport.spec.ts
The global settings schema and extension messages add per-view state records, IDs, and claims. Settings export and import omit viewStates. Tests cover schema validation and import/export behavior.
View registration and state persistence src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts
ClineProvider validates view IDs, checks claim ownership, persists and loads view selections, and prunes saved records to 50 entries. Tests cover registration, claims, persistence, and loading.
View-local settings synchronization and reset src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts
Setting and profile changes synchronize with view-local state. Reset clears the view buffer and persisted entry. Tests cover mutations, persistence failures, rollback, and reset.

Merge Risk: Moderate · previous review 035f1
Saved per-view selections are not restored through the launch path or applied to webview state and new tasks, while mode and profile changes can leave stale saved selections. Fix these integration gaps before merging. Persistence edge cases and tracked generated hooks also need correction.

Full details: Lifecycle Resource Cleanup
Explanation
No concrete lifecycle leak or duplicate-work path was introduced. The changed ClineProvider code adds promise-based view-state persistence and state hydration, but it does not register listeners, watchers, timers, tasks, or providers. The constructor’s initial load exits before any await while the temporary view has no authored state. Claim delivery uses postMessageToWebview, which skips work after disposal. Existing webview resource disposal remains unchanged.
Full details: Security Boundaries
Explanation
Changed path leaks API secrets. ClineProvider._updateViewLocalStateFromMutation copies providerSettings into viewLocalState.apiConfiguration (lines 5379-5401), including keys such as openAiApiKey and awsSecretKey. The changed getValues() then merges that nested object into its result (line 3940). src/extension/api.ts:getConfiguration() only filters top-level secret-key names, so an extension consumer can receive apiConfiguration.openAiApiKey after a user saves or activates a profile through upsertProviderProfile (lines 2596-2606).
Resolution
Do not store secret fields in viewLocalState.apiConfiguration, or redact them with isSecretStateKey before buffering. Also make getConfiguration() explicitly omit or sanitize the nested apiConfiguration object. Add a regression test that saves a profile containing an API key and verifies the public configuration result contains no nested secret.
Full details: Persistence Integrity
Explanation
The changed per-view persistence path cannot restore state in the product. ClineProvider writes viewStates under its temporary viewId and sends a claim (src/core/webview/ClineProvider.ts:609-675), but the new setViewStateId method has no runtime caller. The webviewDidLaunch handler (src/core/webview/webviewMessageHandler.ts:594-702) never passes viewStateId or viewStateClaim, and the webview has no viewStateClaim consumer. After a reload, a new provider receives a new temporary ID (ClineProvider.ts:422-423); loadViewState skips an un-authored temporary entry (ClineProvider.ts:931-936), so the persisted mode/profile is lost to the consumer.
Resolution
Wire the webview to create or restore a stable view ID and claim, store claims received in viewStateClaim, and include both fields in every webviewDidLaunch message. Call and await setViewStateId before posting or consuming initial state. Handle claim-delivery or registration failure with retry or explicit failure handling so a successful durable write cannot leave an inaccessible entry.

Full details: Regression Evidence
Explanation
The successful batch path lacks focused coverage. ClineProvider.setValues writes the shared batch and then persists the per-view subset at ClineProvider.ts:3943-3969. Tests cover a single valid mode value and a combined batch only when persistence fails (ClineProvider.spec.ts:4542-4577, 4644-4671); no test asserts that a successful batch containing both mode and currentApiConfigName reaches shared state, viewLocalState, and the durable viewStates entry. No Playwright snapshot is required because the diff changes no webview-ui production files and is behavior-only.
Resolution
Add a focused ClineProvider.spec.ts success test for setValues({ mode, currentApiConfigName }). Register a stable view, call the batch setter, and assert both values in shared state, viewLocalState, and the persisted viewStates record, including the existing claim/metadata as appropriate.

src/core/webview/ClineProvider.ts:3963-3968 🗄️ Data Integrity & Integration | 🟡 Minor | ⚖️ Poor tradeoff
Serialize the shared rollback, or skip it when a newer shared write has landed.
ClineProvider.setValue and ClineProvider.setValues capture the prior shared value, write the shared store, then roll back that captured value if the per-view write fails. The rollback is unconditional. If another view writes the same shared key between the capture and the rollback, the rollback overwrites that newer value. This is a rare lost update. It does not remove the other view's durable per-view record.
Suggested direction
Use a single queue, or compare the current shared value with the value this call wrote before rolling back. Only restore when the current value still equals the value this call wrote. The proposed edit is not established as safe, so none is included.

src/core/webview/ClineProvider.ts:4040-4045 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Run the reset's viewStates clear inside the shared view-state write queue.
resetState() calls contextProxy.resetAllState() outside ClineProvider.persistedViewStateWriteQueue, then calls clearPersistedViewState(), which is queued. A view write queued before or during the reset can therefore land after the viewStates clear. That write persists another view's selection, and clearPersistedViewState() removes only the resetting view's entry. Run the reset's viewStates clear inside the same queue, so no queued view write can run between the clear and the reset completing.

none can persist another view’s selection after the reset clear and before the

- Around line 4456-4461: Connect the view-state claim to the relaunch handshake
instead of relying on the direct setViewStateId call in this test. Persist the
host-issued viewStateId and claim in the webview, update them when receiving
viewStateClaim, and include them in webviewDidLaunch. In the webviewDidLaunch
handler, pass the received pair to setViewStateId before postStateToWebview; add
focused tests for pair storage, launch payload, and handler ordering, while
keeping the direct-call test limited to claim comparison.
Review comments at @src/core/webview/ClineProvider.ts:
- Around line 1027-1031: Narrow the `saveViewState` key type to the keys handled
by `_saveViewLocalStateFromMutation`: `mode`, `currentApiConfigName`,
`apiConfiguration`, and provider-setting keys. Ensure unsupported settings such
as `customInstructions` cannot be passed as keys.
- Around line 2596-2599: In activateProviderProfileUnlocked, persist the
selected profile for the current view by keeping the
this.setValue("currentApiConfigName", name) update and calling
_saveViewLocalStateFromMutation with the activated providerSettings as
apiConfiguration. Leave the existing skipCurrentTaskRebuild behavior unchanged.
- Around line 3991-4003: Update handleModeSwitchUnlocked to persist the newly
selected mode in the per-view state via savePersistedViewState, so loadViewState
does not restore a stale pinned mode after reload.
- Around line 3939-3941: Update getState() to overlay the restored per-view
values from viewLocalState, including mode, currentApiConfigName, and
apiConfiguration, so webview state and new tasks use this view’s selection. Add
a test verifying that a value restored by loadViewState() is returned by
getState().
- Around line 938-940: Update ContextProxy.updateGlobalState so a rejected write
of viewStates restores the prior cached value before propagating the rejection,
keeping the cache consistent with durable storage. Preserve the existing
successful-write behavior and ensure loadViewState cannot load a selection that
was never persisted.
- Around line 989-995: Update loadViewState to detect buffer writes during the
pending profile load using per-field write counters rather than comparing pre-
and post-load values, so clearing mode to undefined is recognized as a change.
Increment the counters in _updateViewLocalStateFromMutation, snapshot them when
the load begins, and apply the existing merge when a field’s counter changes;
add a test confirming saveViewState("mode", undefined) during a pending
getProfile keeps the mode unset when persisted state contains a mode.
