fix(webview): invalidate live sibling view state on reset and settings import (vps2 F4)

[easonLiangWorldedtech]

Draft PR — vps2 unit F4 (cross-instance reset + import invalidation).

Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1561 (this series' gap record; the original upstream bug is #980). Port source: upstream PR #981 (fix(webview): invalidate per-view state after reset and import) — closed draft, superseded by the vps2 series; the fork issue 41 ledger names #981 as the F4 port source.

What this unit does at head 4f60bbf

1. src/core/webview/ClineProvider.ts — broadcastResetToAllInstances(): every live instance clears its in-memory view-local state (_clearViewLocalState), the single global viewStates clear removes the durable per-view entries in one write-queue clear, and each non-calling instance re-posts its state to its webview. Wired into resetState before its final postStateToWebview(). This round also: the F1a view-identity review fixes are ported into this unit's copy (temporary-id authorship flag, ownsTargetEntry re-key gate, null-prototype viewStates, loadViewState ownership guard, setValue/setValues rollback).
2. src/core/config/importExport.ts — ImportWithProviderOptions gains the optional broadcastResetToAllInstances(); importSettingsWithFeedback broadcasts after the settingsImportedAt write behind a try/catch (a broadcast failure is console.warn'd and never fails the import).
3. src/core/config/tests/importExport.spec.ts — the 3 ported tests (broadcast on success; skip when the callback is missing with a console.warn negative assertion; import stays successful when the broadcast throws).
4. src/core/webview/tests/ClineProvider.parallelMode.spec.ts — the F4 multi-instance + _clearViewLocalState describes (CS-verbatim); this round every construction passes the shared WebviewFocusTracker.
5. src/core/webview/tests/ClineProvider.spec.ts — the F3 resetState sentinel forward fix (viewStates key removed, toBeUndefined) plus this round's ported sticky-mode persisted-view-state-keys suite, rollback tests, and re-key ownership adaptations.
6. src/extension/tests/api-set-configuration.spec.ts — passes the required ClineProviderFactory argument (main's new constructor parameter).
7. Upstream main 793b65b merged (this round): 5 conflicts reconciled both-sides — openClineInNewTab keeps the serialized flow on main's typed options + shared tracker; getState keeps the per-view mergedStateValues reads including main's new alwaysDenyUnapprovedCommands; the non-await postMessage path keeps the original-content strip.

Budget

Unit delta vs the stack base: 5 files, +342/-1 — well under the 400-soft budget. The PR diff vs upstream/main is larger because the branch is stacked on the unmerged F1-F2 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.

How to test

• vitest run src/core/config/__tests__/importExport.spec.ts — import-path broadcast (success, missing callback, throwing broadcast).
• vitest run src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts — multi-instance broadcast + _clearViewLocalState.
• vitest run src/core/webview/__tests__/ClineProvider.spec.ts -t "resetState" — the single global viewStates clear semantics.
• vitest run src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts — per-view state keys incl. the ported persisted-view-state-keys suite.

Verification numbers (head 4f60bbf)

• vitest: ClineProvider.spec + sticky-mode + registerCommands + parallelMode + api-set-configuration 404/407 (the 3 failures are local-only: the donor-built @roo-code/types dist predates alwaysDenyUnapprovedCommands, so globalSettingsSchema strips it locally; CI builds types from source); webview-ui ExtensionStateContext 25/25; packages/types global-settings 9/9.
• eslint --max-warnings=0 clean on all touched files; eslint-suppressions ClineProvider.spec.ts 196 -> 194 (decrease), no count increased.
• Negative control: forcing the re-key ownership check to true reddens sticky-mode "does not merge a stale temporary-id entry"; restored byte-exact (sha256 match).
• Prettier: full-repo check passes on the PR merge tree (merge ref 52a8a93).

Updated this round (c9b08aa -> 4f60bbf)

• Merged upstream/main 793b65b; resolved 5 conflicts with both-sides review (registerCommands + spec, ClineProvider + spec, ExtensionStateContext.spec.tsx).
• Ported the F1a view-identity review fixes into this unit's ClineProvider copy; adapted the re-key tests to author entries through the real write path; ported the sticky-mode persisted-view-state-keys suite, rollback tests and the viewStates global-setting tests.
• Added the required WebviewFocusTracker constructor argument to the 84 ClineProvider.spec and 44 parallelMode.spec constructions; api-set-configuration.spec passes the required ClineProviderFactory.
• Suppression count ClineProvider.spec.ts 196 -> 194.

Mutation gate (carried)

• Unit-delta local Stryker preflight was certified at the pre-merge head; the stacked CI mutation-diff reports a changed-line cap artifact by construction (inherited shared content).

Series mechanics

• PR base is main; the branch is stacked on the F2 head; merge order F1a -> F1b -> F1c -> F2 -> F3 -> F4 -> F5 -> F6 -> F7.
• CS not-ported register (for consistency): kimi-code OAuth try/catch + routerModels.spec +29; ApiConfigManager min-w-0->grow; ApiConfigManager.visual.tsx deletion + 2 PNG baselines; mojibake comment; providers/, .coderabbit.yaml, .github/, CONTRIBUTING.md, .gitignore churn — none of these touch the files in this PR.

Pre-merge ERROR-row pre-check (head 7e649e9)

• Security Boundaries / view-state id rows: addressed at 7e649e9. 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).
• The spec gained an afterEach clearing the static instance registry (suites construct providers directly and never dispose most of them; leaked instances would claim ids ahead of later tests).
• 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 7e649e9: 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) rewrote the profile on disk but left pinned views serving the pre-save snapshot; the non-activating branch now refreshes pinned sibling views (and this view when it holds the pin), and the callback routes through upsertProviderProfile so the refresh cannot be forgotten.
• getState() no longer spreads the pinned overlay over the shared provider settings (a key the profile never defined leaked in from the shared profile: model id, region, tuning). The overlay is a complete snapshot: used in place, with only apiProvider falling back to shared state.
• Regression tests: "refreshes views pinned to a profile saved without activation"; "does not leak shared provider keys into a pinned view's api configuration; the zoo-gateway callback test asserts the upsert path.
• Negative controls: dropping the else-branch refresh reddens exactly the refresh test, reverting the merge semantics reddens exactly the leak test; restores byte-exact (hash match).
• Proofs at 73c0b90: 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: overlay read from the view buffer (required-lane fix)

The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw apiConfiguration state key. That key is a partial patch written by shared-store paths, not a view snapshot: with no overlay present and the raw key partial, getState() served only the partial object and dropped the shared provider settings the previous merge produced (the parallel-mode activation tests caught exactly this - the activated profile's model id vanished; required lane red on the units carrying that spec). The overlay is now read from the view buffer itself, where a present value is by contract a complete profile and an absent one means the shared store serves the settings.

Proofs: ClineProvider.parallelMode.spec green where present (the six synchronization tests that regressed), ClineProvider.spec green including the overlay-completeness tests, sticky-mode and webviewMessageHandler green; negative control: reverting the overlay to a shallow merge over the shared settings still reddens exactly the leak test; restores byte-exact (hash match); 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 59744fd)

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 4b28d3d)

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 db6299d)

A review round on the mode-profile-writes unit found fixes this unit carries. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
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.

Proofs: ClineProvider.spec 287/287, sticky-mode 34/34 (new pin-write-failure rollback test), parallel-mode 37/37 (sibling re-pin test asserts the task handler rebuild and sticky-name re-point); negative controls: dropping the rollback call reddens exactly the rollback test, dropping the rebuild reddens exactly the re-pin test, restores byte-exact (hash match); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.

Updated this round (CodeRabbit follow-up, head 574dfeb)

• Mode-switch atomicity: handleModeSwitchUnlocked now reconciles every write it owns (shared mode, durable view pin, task mode, task history) when a failure lands after the task-mode write - including the mode-linked profile activation - so submitUserMessage delivers the submitted message on the pre-switch mode and profile instead of a half-applied switch. Regression test fails the activation after the task-mode write and asserts all four stores are restored (negative control: reverting the reconcile reddens exactly that test).
• 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 guarded by taskApiConfigName); regression tests cover both sites.
• Test hygiene: prune assertions compare full kept entries; the two re-key storage tests seed through the durable write path so their assertions can fail; sticky-mode afterEach disposes the per-test provider before resetting the instance registry; the webview state-payload test renamed to describe what it asserts.
• Verified: ClineProvider.spec 289 green, sticky-mode 35 green, parallelMode 37 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

---

Updated this round (CodeRabbit follow-up 2, head 1849e73)

• 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); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.
• Verified: ClineProvider.spec 290 green, sticky-mode 35 green, parallelMode 37 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

---

Updated this round (CodeRabbit follow-up 3, head c40a67a)

• Mode-switch reconcile (this unit's thread): the rollback is skipped once the mode-linked activation has started writing shared state - a mode-only rollback would pair the old mode with the profile the activation switched to - and also when the mutation signal has aborted (the queue has advanced; a newer mutation may own the mode stores). The trailing state post now runs outside the reconciled region: a UI-refresh failure after a committed switch is logged, not rolled back. Three regression tests included (negative controls: removing either guard or re-throwing the post reddens exactly one test each).
• Verified: sticky-mode 38 green, ClineProvider.spec 290 green, parallelMode 37 green, eslint --max-warnings=0 clean, tsc real=0, prettier clean.

📝 Summary

Summary by CodeRabbit

• New Features
  • Added persistent, per-view settings for modes and API configurations.
  • Added dedicated title-bar actions for editor tabs that target the correct tab.
• Improvements
  • Reuse open editor tabs and prevent duplicate tabs when opening multiple times quickly.
  • Improved recovery when saved view settings or API profiles are unavailable.
  • Mode changes remain associated with the correct task and view.
  • Settings remain available when browser storage is inaccessible.
• Bug Fixes
  • Settings import and export no longer transfer machine-local view state.
  • Reset and configuration updates synchronize across active views.
  • Submitted messages continue when a mode change fails; unsuccessful tool-based mode changes are reported as failures.

The change adds durable per-view mode and provider selections, stable webview identifiers, tab-specific commands, import/export isolation, and task-scoped mode switching. It also updates profile synchronization, reset handling, and provider configuration writes.

Changes: Per-view state and mode handling

Layer / File(s)	Summary
View identity and persisted state contract packages/types/src/*, webview-ui/src/utils/*, webview-ui/src/context/*	Defines persisted view state and launch identifiers. The webview generates and persists stable identifiers, with in-memory fallback when browser storage fails.
Provider-local state and profile synchronization src/core/webview/ClineProvider.ts, src/core/webview/__tests__/*	Stores mode and provider selections per view, merges local and shared state, validates modes, repairs profile pins, prunes persisted entries, and synchronizes live views.
Launch, import, and task mode integration src/core/webview/webviewMessageHandler.ts, src/core/config/*, src/core/task/*, src/core/tools/*	Registers view state during launch, repairs invalid selections, excludes machine-local view state from imports and exports, broadcasts resets after imports, and passes explicit tasks to mode switching.

Panel commands and lifecycle

Layer / File(s)	Summary
Tab command routing and panel lifecycle src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts, src/package.json, packages/types/src/vscode.ts	Adds tab-specific commands, routes actions to the provider for the tracked panel, shares overlapping tab creation, and handles panel visibility, disposal, and initialization failure.
Provider configuration write routing src/extension/api.ts, src/extension/__tests__/*, src/core/config/ProviderSettingsManager.ts	Routes configuration writes through ClineProvider.setValues and adds a typed error for missing provider profiles.

Loading

Merge Risk: 🟡 Moderate · up to 1849e

Most per-view state, reset, and import isolation work appears sound. However, a failure late in a mode switch can leave a task running in the old mode with the new mode's provider profile. A held error notification can also block later tasks until the user dismisses it. Resolve these before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to c9b08

A failed or overlapping reset can leave an open tab using an outdated provider configuration after settings have changed. New tasks can read that configuration, although the observed scope is the local extension’s open views and task creation still checks the organization’s provider allow-list.

Retained concerns

• Medium · security · inferred: Reset and import do not consistently invalidate every live view: a rejected durable clear stops the sibling loop, and an in-flight state load can restore a selection read before a successful clear. A stale provider-configuration overlay can then remain authoritative for a subsequent task.

Security review details

Security Blast Radius

• inferred — The invalidation boundary covers all live provider instances sharing this extension’s state, rather than an evidenced tenant or remote-service boundary. An affected sibling can retain its local provider overlay until another lifecycle action changes it.

Security Findings and Attack Paths

• inferred — Following a user-initiated settings import, a failed clear—or a load that began before invalidation—can leave a sibling’s older API-configuration overlay in place. A later task in that view can consume it. No unauthenticated trigger, allow-list bypass, or cross-tenant exposure was established.

Trust Boundaries and Controls

• observed — Import sanitizes shared settings and excludes imported view selections; view-state loading checks that modes resolve and attempts to resolve pinned profiles. New task creation applies an organization provider allow-list check.

Resilience and Maintainability Implications

• inferred — Logging and continuing after a broadcast failure preserves the completed import, but leaves no demonstrated retry or recovery step that reconciles sibling buffers with the imported settings.

Hardening Proposals

• proposed — Give invalidation a generation marker checked by in-flight loads, and provide a reconciliation path when the durable clear fails, so import success cannot silently leave live views on pre-import provider settings.

Full details: Regression Evidence

Explanation

Focused regression coverage remains incomplete for the changed browser fallback paths. VSCodeAPIWrapper.createViewStateId() checks only 'randomUUID' in crypto and then calls crypto.randomUUID() at webview-ui/src/utils/vscode.ts:35-40; a present-but-undefined or non-callable value can throw instead of using the fallback. The focused spec covers a missing property and an undefined crypto, but not those callable-capability cases. getState() catches JSON.parse failures at webview-ui/src/utils/vscode.ts:105-113, but webview-ui/src/utils/__tests__/vscode.spec.ts has no test with malformed persisted JSON; its null case is valid JSON.

Resolution

Change the capability guard to require typeof crypto.randomUUID === "function" before calling it. Add focused VSCodeAPIWrapper tests for crypto = { randomUUID: undefined } and a non-callable randomUUID, and add a malformed vscodeState JSON test that verifies getState() returns the in-memory fallback without throwing.

Full details: Security Boundaries

Explanation

The prior security failure remains unresolved. webviewDidLaunch passes renderer-controlled message.viewStateId to setViewStateId (src/core/webview/webviewMessageHandler.ts:583-595). The changed validation only normalizes the string and rejects IDs claimed by live providers (src/core/webview/ClineProvider.ts:758-790). dispose() removes the old provider from activeInstances (ClineProvider.ts:1333), so a crafted webview that knows a disposed view's ID can adopt its persisted entry. loadViewState then loads the named profile from provider settings (ClineProvider.ts:832-859), while getState uses the loaded full apiConfiguration (ClineProvider.ts:3942-3951) and postStateToWebview sends it to the webview (ClineProvider.ts:3362-3366). Provider profiles include secrets loaded from SecretStorage (ProviderSettingsManager.ts:458-490, 670-704). The changed test explicitly demonstrates adoption after the original writer is disposed (ClineProvider.spec.ts:2112-2154).

Resolution

Do not use an arbitrary renderer-provided ID as authorization. Bind each persisted record to an extension-owned webview or panel identity, or use an extension-generated unforgeable token and verify it before loading. Reject IDs not registered for the current provider, including IDs from disposed providers. Add a regression test where a provider submits another provider's persisted ID after disposal and verify that no profile loads. Redact credential fields from state sent to the webview where possible.

Full details: Persistence Integrity

Explanation

The prior persistence failure remains present in the reviewed code. ClineProvider.broadcastResetToAllInstances() awaits the queued durable contextProxy.setValue("viewStates", undefined) at src/core/webview/ClineProvider.ts:4292-4296 before it clears live sibling buffers and posts their state at :4298-4318. If the durable write rejects, no live invalidation or sibling post runs. resetState() awaits this method without recovery at :4359-4362. During import, importSettingsWithFeedback() catches that rejection, logs a warning, and still posts state and reports success at src/core/config/importExport.ts:401-410; stale sibling overlays can therefore remain after a successful import. The added test only verifies that a rejected callback is tolerated (importExport.spec.ts:1205-1262), not that partial invalidation is reported or completed.

Resolution

Clear all live view-local buffers and attempt sibling posts in a finally or equivalent failure-isolation path, even when the durable viewStates clear fails. Preserve or retry the durable-clear failure. Return or record an explicit degraded invalidation result, and make reset and settings import handle that result instead of silently treating stale sibling state as successfully invalidated.

Full details: Lifecycle Resource Cleanup

Explanation

The lifecycle leak remains in the changed tab-creation path. createTabPanelUnlocked registers onDidChangeViewState and onDidDispose into context.subscriptions at lines 434-477 before resolveWebviewView. If initialization rejects, the catch at lines 479-495 removes the panel from liveTabPanels, clears tabPanel, and calls tabProvider.dispose(), but it does not dispose either listener registration. ClineProvider.dispose() only drains provider-owned this.disposables at lines 1315-1321. Repeated failed tab opens can therefore retain listener registrations and their closures in the extension context until extension deactivation.

Resolution

Create a tab-lifecycle cleanup object that stores both listener disposables. Dispose it from the panel disposal handler and from the initialization-failure catch, before or alongside provider disposal. Do not rely on onDidDispose firing for failed or test panels. Ensure successful, disposed, and failed tab paths release each listener exactly once.

🧠 Learnings (1)

📓 Common learnings

Learnt from: easonLiangWorldedtech
Repo: Zoo-Code-Org/Zoo-Code PR: 1562
File: src/activate/registerCommands.ts:252-267
Timestamp: 2026-09-28T02:17:25.615Z
Learning: In `src/activate/registerCommands.ts`, `focusInput` intentionally does not fall back to the sidebar when a tracked tab panel has no live `ClineProvider`. `src/utils/focusPanel.ts` prioritizes and reveals the tracked tab, so `focusInput` logs the dropped action instead of posting it to the sidebar.

Inline comments:
Review comments at @src/core/task/Task.ts:
- Line 2519: Update the mode-switch error handling around
`provider.handleModeSwitch(mode, this)` so a failure after the task mode is
persisted cannot deliver a message with mismatched mode and profile; roll back
the persisted mode or reconcile the profile before delivery, and define explicit
partial-failure behavior for persisted state. Ensure this covers failures
occurring after the task-mode write, not only an initial rejection.

Review comments at @src/core/webview/__tests__/ClineProvider.spec.ts:
- Around line 1871-1874: Strengthen the pruning assertions in the test by
replacing the presence-only checks for pruned["view-54"] and pruned["view-5"]
with equality checks against their complete expected entries, including mode and
updatedAt.

Review comments at
@src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts:
- Around line 1640-1661: Update the sticky-mode tests around
getPersistedViewStates and setViewStateId to use shared backing state that
mockContext.globalState.get reads and globalState.update writes. Assert the
rekeyed state through that backing store so the tests fail when the provider
does not persist the expected change.

Review comments at @src/core/webview/ClineProvider.ts:
- Around line 2875-2888: Update rePinViewLocalStateForDeletedProfile so that,
after saving a sibling’s replacement settings, it rebuilds that sibling’s task
API handler with the replacement settings and force rebuild enabled. Only
rebuild when replacementSettings is available; keep the existing state-posting
flow unchanged.

Review comments at
@webview-ui/src/context/__tests__/ExtensionStateContext.spec.tsx:
- Around line 171-210: Rename the test in the ExtensionStateContext test suite
to describe that a later state payload applies its mode and API profile after
local edits; remove the inaccurate “reseeds” wording while keeping the test
behavior unchanged.
