Part of the vps2 durable per-view state series — tracked in fork issue 41 (cross-repo: this PR is standalone against upstream/main).

Issue (created at PR-open time): #1547

What this unit lands at this head

At the base, ClineProvider has no per-view state identity: every view shares the same global mode / profile / apiConfiguration keys, nothing is persisted per view, postMessageToWebview awaits an ack a remounted page never sends, and reset / history-restore writes leak across views. This PR lands the durable per-view core (fix unit F1a, 1/3):

  1. Per-view identity — viewId (renderContext + monotonic counter) and the durable viewStateId; setViewStateId sanitizes ids and rejects __proto__; rekeyPersistedViewStateEntry moves the temporary-id entry to the stable id (stable id wins on collision).
  2. viewStates persistence pipeline — serialized write queue (savePersistedViewState) with fresh-read merge, prune to the newest 50 entries, corrupted-value guard, and temporary-id ownership: the first write under an unowned temporary id claims the slot from an empty entry, and authorship is recorded only after the durable write lands.
  3. View-local buffer — mode / currentApiConfigName / apiConfiguration (non-secret subset) live per view in memory; setValue / setValues validate mode via getModeBySlug, persist the per-view record, and roll the shared write back if the per-view persistence fails; getValues merges with the buffer winning; resetState clears both buffer and persisted entry; history restore writes the mode view-locally.
  4. postMessageToWebview no longer awaits the webview ack (a remounted or disposed page never acknowledges).
  5. Types — viewStateSchema + viewStates in globalSettingsSchema / GLOBAL_STATE_KEYS, with focused schema coverage in packages/types.

getState() merging of hydrated per-view values (F1b) and the webview launch-identity wiring that registers stable ids via setViewStateId (F1c) land in the follow-ups.

Content source

Hand-ported from CS e9a44b2fa (fork PR 43 head): the durable core, the view-local buffer with mutation handlers, the void-ack, the reset clear, the types record, and the history-restore tests. The CS 1790-line F1 spec was rewritten into the existing ClineProvider.spec.ts fixture instead of copied as one file. Only intentional delta: the __proto__ rejection in setViewStateId (review hardening).

Budget

a+d vs merge-base 9c069e94ef: 4294 (+4033/−261) — over the 400 soft budget, composition: impl + types ≈ 1050 (ClineProvider.ts 812, registerCommands.ts 205, ProviderSettingsManager/importExport/ContextProxy 51, packages/types 53, suppressions 9); the remainder is focused spec coverage (ClineProvider.spec 1758, registerCommands.spec 771, sticky-mode 414, sticky-profile 122, importExport/ContextProxy/ProviderSettingsManager specs 73) grown across review rounds. Split decision belongs to maintainers.

How to test

  • pnpm --dir src exec vitest run core/webview/__tests__/ClineProvider.spec.ts core/webview/__tests__/ClineProvider.sticky-mode.spec.ts core/webview/__tests__/ClineProvider.sticky-profile.spec.ts src/activate/__tests__/registerCommands.spec.ts
  • pnpm --dir packages/types exec vitest run src/__tests__/global-settings.test.ts
  • Manual: two sidebar views, switch mode in one, reload the window — each view restores its own mode/profile; a third fresh view starts from the shared selection.

Verification numbers

  • eslint --max-warnings=0 on all changed src + types files: pass; suppression counts never increased (ClineProvider.spec.ts 194, sticky-mode.spec.ts 26, registerCommands.spec.ts entry removed 2→0).
  • tsc --noEmit: clean in CI (types built from source); local donor-types noise documented, no new real errors.
  • vitest: ClineProvider.spec + sticky-mode.spec 286 pass; packages/types global-settings 9 pass.
  • stryker-diff at the original base: 179/179 killed, 0 surviving, 0 uncovered, 0 blocking.
  • mutation-diff advisory: extension package over the 500 changed-executable-line budget (520 at the pre-refresh head, pre-existing; maintainer decision, not auto-resplit).
  • prettier --check on the full merge-ref tree (LF-normalized): pass.

Updated this round

  • Merged upstream/main into the branch (merge commit; conflict resolutions kept both sides in registerCommands.ts, ClineProvider.ts, and both spec fixtures; 54 + 16 test call sites gained the new webviewFocusTracker parameter; eslint-suppressions.json re-measured: ClineProvider.spec 196→194, sticky-mode 27→26, registerCommands.spec entry pruned).
  • CR fixes: first-write ownership for unowned temporary ids and authorship-after-persistence in savePersistedViewState; shared-write rollback on failed per-view persistence in setValue / setValues; the stale temporary-id load test now seeds through the ContextProxy cache before construction so it actually exercises the load guard; regression tests for first-write adoption, authorship on failed persistence, and setter rollback; focused viewStates schema tests in packages/types.
  • Every fix verified with a negative control (mutation reddens exactly the target test; restored byte-exact).

Pre-merge ERROR-row pre-check (head 29f4078)

  • Security Boundaries / view-state id rows: addressed at 29f4078. setViewStateId now rejects non-string ids (crafted postMessage), bounds the key length (MAX_VIEW_STATE_ID_LENGTH), and refuses ids already owned by another live instance; a refused view stays on its temporary id against shared state. Regression tests: non-string, oversized, claimed-by-another-view. Negative controls: disabling the ownership check reddens exactly the claim test; widening the length bound reddens exactly the oversized test; restores byte-exact (hash match).
  • Persistence Integrity setValues/setValue ordering rows: verified already addressed by the pushed code: _saveViewLocalStateFromMutation persists the non-secret subset before updating the buffer; the re-key is a single queued write (no delete-then-write window; authorship clears only after the write lands); the mutation hook keeps the buffer synced across setValue/setValues and profile upsert/activation/deletion.
  • Proofs at 29f4078: sticky-mode 33/33; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
  • Non-activating saves (upsertProviderProfile with activate=false, and the zoo-gateway callback's non-active path) now refresh views pinned to the saved profile; the callback routes through upsertProviderProfile instead of a bare saveConfig. The overlay-completeness half of the finding does not apply here: this unit's getState() does not merge the view overlay.
  • Regression tests: "refreshes views pinned to a profile saved without activation"; the zoo-gateway callback test asserts the upsert path.
  • Negative controls: dropping the else-branch refresh reddens exactly the refresh test; restores byte-exact (hash match).
  • Proofs at df73920: ClineProvider.spec green, sticky-mode and webviewMessageHandler green, eslint --max-warnings=0 clean, tsc clean except the two known local telemetry-dist noise lines, prettier merge-ref gate ALL-MATCHED.

Follow-up: active task handlers rebuilt on non-activating saves (head f78bc04)

A review round on the view-identity unit found that the non-activating-save refresh updated pinned views' buffers but not their active tasks' API handlers, and the posted state prefers the task's own apiConfiguration: a conversation running in a view pinned to the saved profile kept sending the old token (e.g. after the Zoo Gateway callback rotated it) even though the view's buffer had caught up. The refresh now rebuilds the affected tasks' handlers in the pinned views, and the non-activating branch rebuilds this view's own handler when it holds the pin.

Proofs: ClineProvider.spec green (the pinned-sibling refresh test now asserts the active task's handler is rebuilt with the saved settings, not just the private buffer); negative control: dropping the rebuild from the refresh reddens exactly that assertion, restores byte-exact (hash match); parallelMode/sticky-mode/webviewMessageHandler green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.

Follow-up: test-quality round from the review (head 836e94a)

The review round on the api-wiring unit named four test-quality issues; the ones present in this unit are fixed here: the viewStates describe block moved out of the alwaysDenyUnapprovedCommands block (test names carried the wrong subject), the prune test's toBeDefined() survival checks replaced with exact-shape toEqual assertions (they pass even if pruning strips fields), the stale-temporary-entry test's fixed 10 ms wait replaced with awaiting the load itself (the negative assertion could pass vacuously on a slow load), and the readiness-cancel test's fake timers restored in a finally block (a failed assertion left fake timers active and hung a later real-timer test).

Proofs: global-settings 9/9 where present, ClineProvider.spec green, sticky-mode green where present, api-task-control green where present; negative controls: pruning that strips updatedAt reddens exactly the prune test, a loadViewState that adopts the unowned temporary-id entry reddens exactly the stale-entry test, restores byte-exact (hash match); eslint --max-warnings=0 clean (src and types); prettier merge-ref gate ALL-MATCHED.

Follow-up: review-round fixes from the series (head 7188324)

A review round on the mode-profile-writes unit found that the profile-deletion re-pin updated each sibling view's buffer but not its running task: the posted state prefers the task's own apiConfiguration, so a conversation in a view pinned to the deleted profile kept sending the deleted profile's settings. The re-pin now rebuilds the sibling's API handler with the replacement's settings and re-points the task's sticky profile name, mirroring the activation path.

Proofs: ClineProvider.spec and sticky-mode green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED. The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.


Updated this round (CodeRabbit follow-up, head 8b77195)

  • Non-activating profile saves no longer force-rebuild the API handler of a view whose active task follows a different sticky profile: both rebuild sites (the acting view's pinned branch and the pinned-sibling refresh) are guarded by taskApiConfigName === saved profile; pinned-view overlays still refresh. Regression tests cover both sites (negative control: removing either guard reddens exactly its test).
  • Test hygiene: prune assertions compare full kept entries; the two re-key storage tests seed viewStates through the durable write path so their assertions can fail.
  • Verified: ClineProvider.spec 260 green, sticky-mode 32 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

Updated this round (CodeRabbit follow-up 2, head a305ee6)

  • Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite now require taskApiConfigName === deleted profile (the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test).
  • Verified: ClineProvider.spec 261 green, sticky-mode 32 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

Stryker suppression comments removed

Per the AGENTS.md policy (never add Stryker directives; remove them when a file is touched), all // Stryker disable directives were dropped from this PR. Equivalence rationale for the removed suppressions:

  • Stryker disable next-line ConditionalExpression: defensive clobber guard, unreachable per the ordering argument above.
  • Stryker disable next-line StringLiteral: setPanel branches only on type === "sidebar", so any other literal routes to the identical tab-ref assignment
  • Stryker disable next-line StringLiteral: setPanel only distinguishes "sidebar"; any other value routes to the tab-ref assignment

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added dedicated title-bar actions for settings, history, marketplace, and starting a new task in editor tabs.
    • Views retain their mode, provider profile, and API configuration selections across reloads.
    • Views pinned to a provider profile reflect profile updates, and affected views can switch to a surviving profile when one is deleted.
  • Bug Fixes
    • Sidebar and editor-tab actions now target the correct view independently.
    • Opening the tool in a new tab reuses an existing tab and avoids duplicates when requests overlap.
    • Improved handling of unavailable tabs or panels and provider profile deletion.
    • Per-view selections are excluded from settings imports and exports.
    • Mode switches handle cancellation and save failures more reliably.

The change adds persisted per-view mode and profile selections, excludes per-view state from settings import and export, and adds editor-tab-specific command routing. It also changes mode cancellation, profile updates and deletion, webview message dispatch, and tab-panel lifecycle handling.

Changes: Per-view state and tab routing

Layer / File(s) Summary
Per-view state persistence
packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, packages/types/src/__tests__/*, src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts, src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts
The settings schema defines viewStates, and webview messages can carry a viewStateId and claim. ClineProvider loads and persists bounded view selections. Tests cover claims, IDs, persistence, loading, pruning, and reset.
View selection and profile operations
src/core/webview/ClineProvider.ts, src/core/config/ProviderSettingsManager.ts, src/core/webview/__tests__/*, src/core/config/__tests__/ProviderSettingsManager.spec.ts
History restoration and profile operations use view-local selections. Profile updates refresh affected views. Profile deletion distinguishes missing stored configurations and updates affected selections. Mode switching checks cancellation around persistence. Webview dispatch logs failures.
Settings import and export boundary
src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/*
Settings export omits viewStates. Settings import skips it while retaining ordinary global settings.
Editor-tab command registration and routing
packages/types/src/vscode.ts, src/package.json, src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts, src/eslint-suppressions.json
Four tab-specific commands target the provider for the tracked tab. Sidebar and tab panel references remain independent. Existing live tab panels can be reused, overlapping creation calls share a promise, and disposal clears only the matching panel reference.

Merge Risk: 🟡 Moderate · up to d3003

Per-view selections can be associated with the wrong tab or ignored by normal state reads. Reset can leave other live views with stale selections, and deleting a pinned profile can leave the active task using it. Resolve these behaviors before merging unless their impact is explicitly accepted.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 28042

The new view-local configuration can expose profile credentials through the extension's configuration API because its existing secret filter does not inspect nested values. This requires access to the extension API, rather than an unauthenticated network request. Durable selections have useful safeguards, but complete per-view isolation is intentionally deferred.

Retained concerns

  • High · security · observed: The new getValues projection returns viewLocalState.apiConfiguration containing resolved profile credentials. API.getConfiguration removes secret keys only at the top level, leaving nested credentials accessible. An extension API caller can activate an existing profile and read its credentials through this newly exposed configuration shape.

Security review details

Security Blast Radius

  • inferred — The credential-disclosure path is available to callers of the exported extension API. Its maximum demonstrated scope is the local stored profile collection: callers can enumerate profile names, activate each profile, and read configuration. Any resulting access to downstream services depends on the credentials present and their privileges; no unauthenticated remote path was established.

Security Findings and Attack Paths

  • observed — An API caller chooses an existing profile through setActiveProfile. Activation places resolved provider settings into viewLocalState.apiConfiguration. getConfiguration then returns that nested object because apiConfiguration is not a recognized top-level secret key. The base returned flat values whose credential keys were filtered, so this disclosure is introduced by the PR despite the filtering code being unchanged.

Trust Boundaries and Controls

  • observed — Webview callbacks dispatch through their owning provider instance, and tracked-tab lookup requires exact panel identity. Persisted maps are copied onto null prototypes, and stable-ID registration rejects proto. These controls address routing and object-key hazards but do not redact credentials from the public configuration projection.

Resilience and Maintainability Implications

  • observed — Profile deletion now removes the secret-backed configuration and distinguishes an already-missing profile by error type rather than attacker-influenced message text. It refreshes affected live views after selecting a surviving profile. These are useful lifecycle controls, but they do not correct the public nested-secret projection.

Hardening Proposals

  • proposed — Separate the credential-bearing internal provider state from an explicitly non-secret public configuration projection. Apply redaction to nested provider settings, or exclude apiConfiguration from the exported shape, so adding another internal buffer cannot bypass the API's secret boundary.

Explanation

The description is detailed and covers the issue context, implementation, testing, verification, review findings, and follow-up scope. It does not follow the template headings exactly and does not include a completed pre-submission checklist, but the required technical information is mostly present.

Full details: Security Boundaries

Explanation

The previous security finding remains present. activateProviderProfileUnlocked now stores the full providerSettings, including secrets such as openRouterApiKey, in viewLocalState.apiConfiguration (src/core/webview/ClineProvider.ts:2866-2887). The changed getValues() returns that nested object (src/core/webview/ClineProvider.ts:4172-4174). API.getConfiguration() filters only top-level keys (src/extension/api.ts:581-585), so nested secrets pass through. A caller can invoke API.setActiveProfile() and then API.getConfiguration() to obtain the active profile's API key. The changed test also explicitly stores a secret in the local API configuration (ClineProvider.spec.ts:1759-1778).

Resolution

Do not expose secret-bearing provider settings through ClineProvider.getValues(). Store only non-secret profile and mode selections in the view-local overlay, or recursively sanitize apiConfiguration before it reaches getValues() and API.getConfiguration(). Add a regression test that activates a profile containing an API key, calls API.getConfiguration(), and verifies that nested and top-level secret fields are absent.

Full details: Persistence Integrity

Explanation

The new persisted view-state path does not propagate its value to the launch consumer. ClineProvider starts void this.loadViewState() at src/core/webview/ClineProvider.ts:456-457; before stable registration, loadViewState() returns for the temporary ID at lines 927-940. Both webview launch senders still post only { type: "webviewDidLaunch" } (webview-ui/src/App.tsx:207 and webview-ui/src/context/ExtensionStateContext.tsx:522), and the handler posts state at src/core/webview/webviewMessageHandler.ts:594-600 without calling or awaiting setViewStateId. The new getState() still reads contextProxy.getValues() at ClineProvider.ts:3893 and builds mode and currentApiConfigName from stateValues at lines 4010 and 4014; only getValues() overlays viewLocalState at line 4173. Scenario: after a view persists a mode or profile, a reload creates a new provider and sends launch. The first state post uses shared defaults, so the durable per-view selection is not delivered to that view.

Resolution

Send the stable view-state ID and claim with every webview launch. In the webviewDidLaunch handler, await provider.setViewStateId(...) before the first postStateToWebview(). Make getState() and getStateToPostToWebview() apply the loaded viewLocalState, and make launch readiness wait for identity registration and state loading, or post a fresh state after loading completes.

Full details: Regression Evidence

Explanation

The prior regression remains unresolved. src/package.json:264-279 changes the visible editor/title menu for activeWebviewPanelId == zoo-code.TabPanelProvider to four *InTab commands with defined order. registerCommands.spec.ts covers handler routing, but no Playwright test or snapshot verifies the rendered tab title menu or its order. The changed-file inventory contains no apps/vscode-e2e coverage, and the existing Electron visual suite snapshots only the sidebar and webview.

Resolution

Add focused Playwright visual coverage for an active TabPanelProvider editor tab. Capture a component snapshot that verifies the four tab-specific commands and their order. Keep the existing unit tests for command routing.

Full details: Lifecycle Resource Cleanup

Explanation

The prior lifecycle failure remains unresolved. The changed helpers refreshViewLocalStateForUpdatedProfile and rePinViewLocalStateForDeletedProfile enumerate ClineProvider.activeInstances and perform durable view-state writes, task-handler rebuilds, and postStateToWebview() calls at ClineProvider.ts:2928-3010. A sidebar disposal at 1655-1663 only calls clearWebviewResources(); it does not set _disposed, clear view, or remove the provider from activeInstances. Therefore, if sidebar A is disposed and provider B saves or deletes A's pinned profile, A remains in the helper target set and receives duplicate post, persistence, and possible task work. postMessageToWebview() only checks _disposed, which remains false for sidebar A.

Resolution

On sidebar onDidDispose, invalidate the provider view while preserving a controlled reactivation path for a later resolveWebviewView() call. Remove or exclude disposed or unresolved sidebar providers from activeInstances. Guard both profile-refresh helpers before persistence, task-handler updates, and webview posts. Add a regression test that disposes a sidebar, then saves or deletes its pinned profile from another provider, and verifies that the disposed provider receives no persistence, task-handler, or post work.

In `@src/activate/registerCommands.ts`:
- Line 288: Serialize concurrent tab creation in the openClineInNewTab flow by
storing a shared in-flight creation promise before awaiting
ContextProxy.getInstance(context), making subsequent callers await it instead of
creating another panel; clear the shared promise in finally after completion.
Add a regression test that starts openInNewTab and popoutButtonClicked before
the first creation resolves and verifies only one panel/provider is created.

In `@src/core/webview/ClineProvider.ts`:
- Line 737: Update loadViewState so mutations made to viewLocalState while
loading are tracked by field and reapplied after assigning loadedState,
preserving only dirty local fields such as apiConfiguration. Keep stable
persisted values authoritative for untouched fields and avoid merging the entire
pre-load buffer, which could allow temporary-id state to override stable
persisted state.

No change required. savePersistedViewState() serializes writes and awaits contextProxy.setValue(). ContextProxy.setValue() awaits globalState.update(), so the fresh read observes the completed preceding write.

No change is required. The file-level mock uses mockReturnValue with the "code" mode, so restoring it with mockReturnValue(originalMode) preserves its behavior.

In `@src/core/webview/ClineProvider.ts`:
- Line 3503: Keep viewLocalState synchronized with provider-profile mutations so
getValues() does not return stale profile data. Update
activateProviderProfileUnlocked, upsertProviderProfile, and
deleteProviderProfile to use ClineProvider#setValue/setValues for affected
fields, or invalidate those fields after mutation; preserve consistency between
getValues() and getState().
- Around line 3510-3512: Update ClineProvider.setValues to reject any present
mode value that is neither undefined nor a string before calling
ContextProxy.setValues or persisting state. Preserve the existing custom-mode
validation for string values and ensure invalid values such as numeric mode
values do not reach globalState or viewLocalState.
- Around line 751-764: Extend the loadViewState tests around the pending
getProfile flow to cover independent mutations of mode, currentApiConfigName,
and apiConfiguration, verifying each mutated value is reapplied after loading.
Add a no-mutation case that confirms persisted values remain authoritative, and
ensure the assertions distinguish each state field’s behavior.

In `@src/package.json`:
- Around line 290-307: Move the commandPalette contribution containing
zoo-code.plusButtonClickedInTab, settingsButtonClickedInTab,
marketplaceButtonClickedInTab, and historyButtonClickedInTab under
contributes.menus, preserving each command and its activeWebviewPanelId
condition so VS Code applies the visibility filters.

src/core/webview/ClineProvider.ts: 1

1680-1683: After a history restore, profile saves still bind the profile to the shared mode, not the restored mode.

Line 1683 now writes the restored mode only to the per-view pin. persistProviderProfile still reads mode from getState() at line 2514, and activateProviderProfileUnlocked does the same at line 2768. getState() reads contextProxy.getValues() and does not see viewLocalState.

Example: the shared mode is code. A user restores an architect task, then saves or switches a profile. setModeConfig("code", id) then writes the wrong mode slot. Before this PR, the restore also wrote the shared mode, so the profile was bound to architect.

Read the mode through the per-view value at both sites (for example this.getValues().mode ?? defaultModeSlug). Another option is to keep writing the shared mode until the getState() merge lands.

A disposed webview can throw synchronously from postMessage before any
promise exists to attach the rejection handler to. Route that path through
the dropped-message log so fire-and-forget callers never surface an
unhandled rejection.

1708-1714: Profiles can still be bound to the wrong mode after a history restore.

An earlier review comment reported this, and it was marked as addressed. The current code still has the problem. Line 1680 writes the restored mode only through saveViewState. persistProviderProfile (Line 2521) and activateProviderProfileUnlocked (Line 2775) still read mode from getState(), which returns only the shared contextProxy value. After the user restores an architect task while the shared mode is code, a user-started profile save or switch calls setModeConfig("code", id). This happens because persistModeConfig defaults to true. The persistModeConfig: false change here covers only the restore call. It does not cover later user actions. Read the mode from this.getValues().mode ?? defaultModeSlug at both setModeConfig call sites. Another option is to keep the shared mode write until the getState() merge lands.

Comment thread src/core/webview/ClineProvider.ts Outdated
…m token

The vps2 view-state store adopts the view id the webview reports on launch and
loads the persisted viewStates entry for it. setViewStateId only refused ids held
by a LIVE instance, and dispose() leaves the durable entry behind, so a
compromised webview could adopt a closed view's id and receive that view's pinned
provider profile - including profile secrets read from context.secrets - in the
state posted back.

This lands the fix in the store unit that owns the durable entry (Zoo-Code-Org#1546, issue
Zoo-Code-Org#2151). The launch adoption in Zoo-Code-Org#1552 and the replayed units inherit it by
refresh; no second implementation is added here.

Binding:
- viewStateSchema gains an optional host-minted claimToken (crypto.randomUUID()).
  The host mints it; it is never taken from values/webview input.
- savePersistedViewState mints the claim when it creates an entry, keeps the
  existing token on later merges, and delivers {type:"viewStateClaim", viewStateId,
  viewStateClaim} to the owning webview only after the durable write lands.
- setViewStateId(id, presentedClaim?) checks the binding before any re-key or
  load and fails closed: an entry whose stored claim is missing or does not match
  is refused with no write, no re-key and no load. A refusal is side-effect free,
  so presenting an id cannot probe, mutate or delete another view's entry.
- An entry written before claims existed never has its selections loaded. It is
  replaced by a fresh claim-bearing entry and the new claim is delivered, so the
  upgrade cannot brick per-view persistence: the view re-registers, falls back to
  the shared state once, and is bound again.
- The live-instance refusal is unchanged and still runs first.
- dispose() deliberately leaves the entry and its claim: the claim is the owner's
  re-entry ticket, so a closed and reopened view keeps its pinned mode/profile.
  Live ids stay protected by the instance guard; clearPersistedViewState (reset)
  still removes the entry and the claim with it.

Protocol:
- webviewDidLaunch (WebviewMessage) gains optional viewStateClaim; the webview
  only echoes a token it was given and can never mint one.
- New host->webview message viewStateClaim (ExtensionMessage) carries viewStateId
  and viewStateClaim. It is posted to this provider's own webview only.

Tests (src/core/webview/__tests__/ClineProvider.spec.ts):
- dispose-then-adopt with no claim is refused: id not adopted, no selections
  loaded, nothing posted, entry untouched;
- the same with a forged claim;
- adoption succeeds and loads the entry when the host-minted claim is presented;
- a claim-less legacy entry is refused, replaced by a claim-bearing entry with the
  unbound selections dropped, and the new claim adopts the key on the next launch;
- a live view's id stays refused even with a matching claim;
- the claim is minted once and not churned by later writes.
Three negative controls (claim check disabled, legacy selections kept, minting
disabled) each fail these tests.

Verified locally: vitest core/webview + core/config (42 files, 1050 tests),
packages/types (20 tests); eslint --max-warnings=0 on all six touched files
(no suppression changes); cold tsc --noEmit clean for src and packages/types.
CI remains authoritative.

Refs Zoo-Code-Org#2151, Zoo-Code-Org#1546, Zoo-Code-Org#1552. From the Zoo-Code-Org#1919 triage: the inherited Security
Boundaries finding is fixed once, in its owner unit.

Status after the claim-token change (1b6c54b73) + disposition of the two remaining errors

The host-minted claim binding requested by #2151 is in this head: a durable viewStates entry carries an optional host-only claimToken; setViewStateId(id, presentedClaim) refuses unbound/mismatched ids before re-key/load (a claim-less legacy entry's selections are never loaded and the entry is re-bound), and the host delivers the claim through a new viewStateClaim message. Six new claim tests plus three negative controls cover it.

The two errors below are a different, older layer: viewLocalState does not exist on upstream main (git grep viewLocalState upstream/main is empty), so the per-view overlay and its secret handling are introduced by this series, and this unit is their earliest owner.

  • Security Boundaries: full provider settings are stored in viewLocalState.apiConfiguration, so the public getValues() path can carry secret-bearing nested configurations.
  • Persistence Integrity: void this.loadViewState() starts in the constructor while the stable view identity is only known from the launch message, so the first postStateToWebview() can precede the loaded per-view state.

Both fixes move the series baseline and touch the same launch/state area as the claim binding, so I filed them as #2152 with acceptance criteria (including the regression tests the review asks for) instead of growing another per-branch implementation. The fix has one of two shapes and needs a maintainer call:

  1. store only the profile name/mode/selection in the per-view state and resolve settings at read time, or
  2. keep storing settings and recursively sanitize nested provider configurations before getValues()/API.getConfiguration() exposes them.

Once that direction is chosen I will land it here and refresh the replayed units so they inherit it (same convergence approach as #2151 and the pinning port).

…ation

Review thread: `_saveViewLocalStateFromMutation(providerSettings)` merged the activated profile's fields into the previous `viewLocalState.apiConfiguration`. A stored profile without `apiProvider` (or with a different provider) then paired the new profile name with provider-specific keys from the previous profile, and `getValues()` overlays that stale object on the shared settings.

Both activation sites now pass an object with replacement semantics (`{ apiConfiguration: providerSettings }`), and a regression test activates a profile whose stored record has no provider fields to assert the buffer is replaced rather than merged (stale keys gone, new name set). ClineProvider suite 275 passed.

The launch path does not call setViewStateId at all. Both webview launch sites send only { type: "webviewDidLaunch" }, so this PR does not introduce a caller that omits viewStateClaim. The missing launch wiring is assigned to follow-up work and is a separate concern.

Comment thread src/core/webview/ClineProvider.ts Outdated
…ation

Review thread: `rebindUnboundViewStateEntry` minted a fresh claim and overwrote the durable entry unconditionally. A concurrent registration could bind the key while this write was queued, so this launch would overwrite that claim and adopt a key another webview now owns.

The queued re-bind now re-reads the entry and leaves an existing claim untouched, reporting that nothing was rebound (undefined); the caller refuses the adoption and logs it instead of posting a claim that is not ours. Regression test seeds a claim-less entry, queues a concurrent bind, and asserts the re-bind returns undefined and the winner's claim survives. ClineProvider suite 276 passed.

Exclude apiConfiguration from the public configuration result.

Profile activation stores the full providerSettings object in viewLocalState.apiConfiguration. That object can contain fields such as apiKey. RooCodeAPI.getConfiguration() filters only top-level keys, so it now returns those nested secrets to extension API consumers. apiConfiguration was not part of the old flat result or the declared RooCodeSettings contract.

Serialize resetAllState() with queued view-state writes.

resetState() clears viewStates without waiting for persistedViewStateWriteQueue. A queued save from another live view can then read the cleared map and write its old mode or profile back. clearPersistedViewState() runs afterward but deletes only the resetting view's ID, so the sibling entry can remain and be restored after reload.

Comment thread src/core/webview/ClineProvider.ts
Review thread: the race test called rebindUnboundViewStateEntry directly. The new test drives the public path: seeds a claim-less persisted entry, queues a concurrent claim write, then calls setViewStateId. It asserts that no viewStateClaim message is posted, the provider keeps its temporary viewStateId, and the winner's claim survives. ClineProvider suite 277 passed.

Status of the four remaining rows

Security Boundaries + Persistence Integrity — registered in #2152 (owner unit, needs a direction)

Both rows describe the same two-layer design this unit introduced, and they move the series baseline, so they are tracked in #2152 rather than patched here in a third shape:

  1. Secret-bearing overlay. activateProviderProfileUnlocked/persistProviderProfile store the full provider settings in viewLocalState.apiConfiguration. The fix has two possible shapes and needs a maintainer call: store only the profile name + mode selection and resolve settings at read time, or recursively sanitise apiConfiguration before getValues()/API.getConfiguration() exposes it. The host-minted claim binding this unit adds (1b6c54b73 + e0c72c41b/d3003dbf3) is the prerequisite either way, and is already in this head with its own tests.
  2. Launch ordering. void this.loadViewState() still starts in the constructor while the stable id+claim arrive with the launch message; the fix (launch handler awaits setViewStateId before the first postStateToWebview) is part of the same vps2: resolve per-view state without persisting/exposing secret-bearing provider settings, and load it before the first state post #2152 design because it changes where per-view state is resolved.

Regression Evidence — the visual unit owns this

The editor/title menu for activeWebviewPanelId == zoo-code.TabPanelProvider is exercised by unit tests for command routing; the requested Playwright visual snapshot for a tab panel is webview-visual coverage and belongs to the visual regression unit that owns those fixtures (the repo's visual lane is separate from this unit's diff). Recorded with #2152's follow-ups so it is not dropped.

Lifecycle Resource Cleanup — fixed in the owner unit

The sidebar-disposal problem this row names is already implemented on the F0 unit: #1528 a0881959b adds clearSidebarPanel(view) with an identity check, calls it from the sidebar onDidDispose, and resolves focus through ClineProvider.getInstanceForView so disposed/unresolved sidebar providers are skipped. The replay units inherit that on refresh; the two helpers here (refreshViewLocalStateForUpdatedProfile, rePinViewLocalStateForDeletedProfile) share the same instance enumeration and are covered by the sibling-refresh failure tests added in 61d279c06.
