feat(webview): per-view ack, history and profile restore writes (N5, split 5/5 of #1546) - #2237
Split unit N5 of #1546 (per-view ack, history and profile restore writes)
Final unit of the split plan (tracking issue: fork issue 41), on top of N4 (#2236). Completes the pure F1a content.
Scope
postMessageToWebview posts synchronously without awaiting the webview ack, with the per-view state ack wired through the message listener.
History restore (createTaskWithHistoryItemUnlocked, updateTaskHistory) and mode switch (handleModeSwitchUnlocked) keep the per-view buffer/persisted entry authoritative.
Profile activation/delete re-pins the view-local state; handleZooCodeCallback and dispose clean up per-view state without leaking another view's entry.
Focused tests for ack ordering/logging, restored-mode validation and profile-sync behaviour.
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.
Final split unit N5: non-awaiting postMessageToWebview with view-state ack, history restore via createTaskWithHistoryItemUnlocked/updateTaskHistory, profile activation/delete re-pin, handleModeSwitchUnlocked and dispose cleanup. Completes the pure F1a content.

Summary
Summary by CodeRabbit
New Features
Modes, provider profiles, and API configurations are managed independently for each view, preserving selections when switching between views.
Returning to a task restores its mode and associated provider profile for that view.
Improvements
Settings imports continue to apply supported settings while ignoring saved per-view selections; exports omit those selections.
Updates to modes and provider profiles are more reliable when changes happen quickly or a view is reset.
Bug Fixes
Removing a provider profile that is no longer available handles the stale selection more cleanly.
The extension adds claim-bound per-view settings for modes and provider selections. ClineProvider restores and synchronizes these settings across task-history and profile workflows. Global-state writes track generations to guard cache recovery after failures and resets. Webview message dispatch no longer waits for renderer acknowledgement.
Per-key write generations guard cache recovery after failed writes and resets. Tests cover overlapping failures and export filtering.

ClineProvider validates view IDs and claims, persists and loads selections, and handles ownership, pruning, and asynchronous lookups.

Task restoration, mode changes, and profile operations update view-local state. Missing profiles use a typed error. Tests cover profile synchronization, deletion, and persistence failures.
The mutation check fails for this PR, and several mode and profile failure paths remain inconsistent. Resolve the gate failure and the active state-handling concerns before merging.

Explanation
The title names a feature (per-view ack, history and profile restore writes) that matches the changeset's core themes: per-view view-state handling in ClineProvider, postMessageToWebview ack behavior, history restore, and profile activation/deletion. It is somewhat dense and uses internal split-plan labels (N5, split 5/5 of #1546) that add noise, but it still refers to the real main change. The title is a single sentence, but at 88 characters it is longer than the short, concise title the guidelines prefer.
Full details: Security Boundaries
Explanation
The prior secret-leak finding remains present in changed code. activateProviderProfileUnlocked now copies the credential-bearing providerSettings into viewLocalState.apiConfiguration (src/core/webview/ClineProvider.ts:3224-3229), and the changed getValues() returns that buffer (:4493-4495). API.getConfiguration() filters only top-level keys (src/extension/api.ts:626-629), so nested fields such as apiConfiguration.apiKey are returned. A caller can activate a profile containing an API key, then retrieve it through getConfiguration().
Resolution
Do not expose credential-bearing apiConfiguration through ClineProvider.getValues() or API.getConfiguration(). Return only non-secret configuration, or recursively redact every secret field in nested profile objects. Add a regression test that activates a profile containing apiKey and verifies that getConfiguration() contains no nested credentials.
Full details: Persistence Integrity
Explanation
Changed persistence paths still allow state loss and partial commits. savePersistedViewState stores a claim, then postViewStateClaimToWebview discards the delivery promise; postMessageToWebview returns when the view is absent or disposed and only logs rejected delivery. If a claim is not delivered, the next setViewStateId rejects the missing or mismatched claim, so the persisted view entry cannot be restored. Profile writes also lack compensation: persistProviderProfile saves the profile before its Promise.allSettled activation writes, including the new per-view write; a failed write leaves successful profile/list/mode/shared writes committed. activateProviderProfileUnlocked changes manager selection before Promise.all writes the list, shared settings, and per-view state; a rejection leaves prior or still-running writes committed. deleteProviderProfile removes the stored profile before writing the list and repairing selections and view pins; a later failure leaves the profile deleted with stale state. These are changed paths in ClineProvider.ts and match the check's explicit failure conditions.
Resolution
Make claim delivery awaited and bounded. If delivery fails or the webview is unavailable, retry or revoke the stored claim so a persisted entry cannot become inaccessible. Make profile save, activation, and deletion transactional, or add compensation for each committed profile secret, manager selection, profile list, mode mapping, shared provider setting, and per-view value. If full compensation fails, return and log an explicit partial-failure result. Add failure-injection tests where claim delivery and each profile operation fail after earlier writes succeed.
Full details: Description check
Explanation
The description follows the repository template structure only partially. It gives scope, budget, evidence, and stack/merge order, and it links the tracking issue as a reference ('Refs: #1546, tracking issue 41 (fork)'). It does not use the template's 'Closes: #<issue>' line, so the required approved GitHub issue link is missing or unclear. The Description, Test Procedure, Pre-Submission Checklist, Visual Snapshots, Documentation Updates, and Get in Touch sections are absent or not filled in as the template asks. The description also does not explicitly state a test procedure beyond the reported test counts, and it does not address the checklist items such as documentation impact or the visual snapshot requirement for UI changes. The description uses a split-plan jargon that a reviewer outside the project may not understand.
Resolution
Add a 'Closes: #<issue number>' line that links an approved GitHub issue. If the fork tracking issue is not an approved GitHub issue for the upstream repository, link the approved issue instead. Fill in the 'Test Procedure' section with the steps to reproduce the tests, including the exact vitest command and the test environment. Complete the Pre-Submission Checklist, and mark the Documentation Updates item. Explain the 'how' in the Description section, including the key design choices such as the generation-guarded rollback and the 50-record cap on closed views. State whether any UI change needs a visual snapshot in webview-ui. Replace or define the split-plan jargon (N4, N5, F0, F1b) for reviewers who do not track the stack.
Full details: Regression Evidence
Explanation
Changed profile-deletion behavior still lacks focused coverage for its negative and durable-state branches. deleteProviderProfile now treats ProviderSettingsNotFoundError as idempotent cleanup, rethrows other deleteConfig failures, and repairs per-view state after deletion (src/core/webview/ClineProvider.ts:2994-3019, 3074-3130). The three focused tests added in ClineProvider.spec.ts:5601-5767 mock only successful deletion; none covers either rejection path or asserts the durable viewStates entry after re-pinning an active or sibling view. The tests cover some in-memory repair and task rebuilding, but do not cover the changed negative branches or durable-state outcomes.
Resolution
Add focused ClineProvider tests that make deleteConfig reject with ProviderSettingsNotFoundError and assert idempotent completion, stale-list pruning, shared-state repair, view-local repair, and durable viewStates repair. Add a test for an unexpected deleteConfig error that asserts rejection and no cleanup. Add deletion tests for the active profile and a profile pinned only in another live view, and assert the survivor selection and durable entries for every affected view.
Full details: Lifecycle Resource Cleanup
Explanation
The changed mode-switch path continues after cancellation. enqueueProviderProfileMutation aborts the signal when its 30-second timeout expires (ClineProvider.ts:374-381). The new await this.setValue("mode", newMode) can wait on the serialized durable view-state write (ClineProvider.ts:2636-2637, 4472-4475). When that write later resolves, the handler emits ModeChanged at line 2645 before its next abort check at line 2659. With the workspace lock enabled, it can also post state and return without checking the signal. The current tests cover an already-aborted signal and cancellation during config reads, but not cancellation while setValue is pending (ClineProvider.spec.ts:5268-5310).
Resolution
Check signal?.aborted immediately after await this.setValue("mode", newMode) and return before ModeChanged. Check the signal after each remaining awaited operation in the mode-switch path, including task-history update, workspace-lock state post, profile-list write, profile lookup and activation, mode-config write, and final webview post. Add a regression test that stalls the durable viewStates write past PENDING_OPERATION_TIMEOUT_MS, resolves it after timeout, and verifies that no post-cancellation mode event, profile mutation, or webview dispatch occurs.

src/core/webview/ClineProvider.ts:2361 🗄️ Data Integrity & Integration | 🟡 Minor | ⚖️ Poor tradeoff
Move the TaskModeSwitched emit and _taskMode update after the per-view write.
TaskModeSwitched fires and _taskMode changes before the per-view setValue("mode") write. If that write fails, the error propagates, but the event and task mode stay changed. Observers see a rejected switch, and a reload restores the previous view selection. Reordering is not verified safe, so no diff is proposed. Check ModeChanged and profile-activation ordering before changing it.

Minor · Refresh sibling view buffers when a profile changes. · ClineProvider.ts:2898-2900
src/core/webview/ClineProvider.ts:2898-2900 🎯 Functional Correctness | 🟡 Minor | 🏗️ Heavy lift
Refresh sibling view buffers when a profile changes.
getConfiguration() reads the sidebar view's buffer through getValues(), and the buffer overrides the shared store. The buffer keeps a copy of profile P's apiConfiguration from loadViewState(). When another view activates or saves P, the sidebar buffer is not updated, so getConfiguration() can return the old P settings.
The sibling-refresh comments at src/core/webview/ClineProvider.ts:2898-2900 and in the activation branch of persistProviderProfile describe a refresh that the code does not perform. The save-only branch at lines 2702-2716 refreshes only the pinned current view.
Do not replace the buffer with shared-store values. Each view keeps its own pinned profile in that buffer. Instead, refresh the buffered apiConfiguration of every other live view that holds P when P is saved or activated. Alternatively, resolve the buffered profile from providerSettingsManager when getConfiguration() runs. Update the comments to match the behavior that is implemented. The comments that say getState() is shadowed are inaccurate, because getState() reads the shared store.

src/core/webview/ClineProvider.ts:4108-4110 🎯 Functional Correctness | 🟡 Minor | 💤 Low value
Restored history mode is missing from the posted state during restore.
History restore now writes the mode only to the view buffer. Profile activation then posts state before the restored task exists, so the webview receives the pre-restore shared mode until a later post. The base wrote the shared mode before this post, so the stale window is new.
This changes only the posted mode field. getState() and profile binding stay unchanged, and an active task keeps precedence through currentTaskMode.

Update the restored mode selection used for the state returned by getValues so
it checks viewLocalState.mode after currentTaskMode and before the shared mode
and default; preserve active-task precedence and leave getState and profile

Assert the restored mode in the deleted-mode sticky-mode test.
The PR removes the only assertion on the fallback slug during history restore. The remaining test, should handle mode deletion between sessions, checks only that createTaskWithHistoryItem resolves and that handleModeSwitch is not called with "deleted-mode". If the fallback were removed, historyItem.mode would stay "deleted-mode" and this test would still pass.
The suggested assertion must not use defaultModeSlug as a bare identifier. The sticky-mode spec does not import it. Use the literal "code", which matches this spec's mocked defaultModeSlug.
🧪 Suggested test assertion
In src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts, inside should handle mode deletion between sessions:
// Initialize task with history item - should not throw
await expect(provider.createTaskWithHistoryItem(historyItem)).resolves.not.toThrow()
// Verify mode switch was not called with deleted mode
expect(handleModeSwitchSpy).not.toHaveBeenCalledWith("deleted-mode")

The review thread on the seeding suite measured true against 45795c8: every seeding case
put a single zoo-gateway profile in the store, where a first-only check, a last-only check,
an every-profile check and the shipped any-profile guard all take the same branch, and the
case titled "...stale or missing token" never left zooSessionToken unset.
Added three cases, with the production guard untouched. Two run through it.each over a store
of ["Zoo Gateway", "Other", "Zoo Gateway 2"] where "Other" is an anthropic profile: one with
the stale profile last, one with it first; each asserts handleZooCodeCallback ran with the
fresh token and that getProfile was never asked about "Other", which is what exercises the
apiProvider filter. The third gives a zoo-gateway profile with a current base URL and no
token at all, and asserts seeding still runs.
Controls, each applied to src/core/webview/ClineProvider.ts, measured, then reverted (the
file's blob is ee8203a before and after, and git checkout HEAD -- confirmed it):
zooGatewayProfiles.slice(0, 1) fails the stale-last case; .slice(-1) fails the stale-first
case; replacing the apiProvider filter with () => true fails the "Other" assertion in the
stale-last row; requiring a non-null token before comparing fails the no-token case. Every
mutation kills exactly one test and nothing else.
vitest core/webview + core/config: 44 files / 1299 tests green (1296 before this commit, plus
the three new cases). prettier --check, tsc --noEmit -p . and eslint --max-warnings=0 are
clean; scope unchanged at 810 extension-package executable lines (no production change).

The extension diff exceeds the 500-line mutation-gate limit, so the mutation CI step fails.
The checked-in gate in scripts/stryker-diff.mjs counts changed executable lines per package. It throws when a package exceeds MAX_CHANGED_LINES = 500. The pull-request step in .github/workflows/mutation-testing.yml runs this gate on the reviewed tree. For the extension package, the count is 561 lines: ClineProvider.ts contributes 542, ContextProxy.ts 10, ProviderSettingsManager.ts 7, and importExport.ts 2. ClineProvider.ts exceeds the limit by itself.
If this check is required by branch protection, the PR cannot pass ordinary merge checks until the count drops to 500 or below.
Do not raise the limit or add a file exclusion to pass this gate. Split the change so each PR stays within the checked-in threshold. A narrow exclusion needs a maintainer decision and a reviewed change to the gate script.

closed views. State whether any UI change needs a visual snapshot in webview-ui.
Replace or define the split-plan jargon (N4, N5, F0, F1b) for reviewers who do
not track the stack.
- Regression Evidence:
Add focused `ClineProvider` tests that make `deleteConfig` reject with
`ProviderSettingsNotFoundError` and assert idempotent completion, stale-list
pruning, shared-state repair, view-local repair, and durable `viewStates`
repair. Add a test for an unexpected `deleteConfig` error that asserts rejection
and no cleanup. Add deletion tests for the active profile and a profile pinned
only in another live view, and assert the survivor selection and durable entries
for every affected view.
- Security Boundaries:
Do not expose credential-bearing `apiConfiguration` through
`ClineProvider.getValues()` or `API.getConfiguration()`. Return only non-secret
configuration, or recursively redact every secret field in nested profile
objects. Add a regression test that activates a profile containing `apiKey` and
verifies that `getConfiguration()` contains no nested credentials.
- Persistence Integrity:
Make claim delivery awaited and bounded. If delivery fails or the webview is
unavailable, retry or revoke the stored claim so a persisted entry cannot become
inaccessible. Make profile save, activation, and deletion transactional, or add
compensation for each committed profile secret, manager selection, profile list,
mode mapping, shared provider setting, and per-view value. If full compensation
fails, return and log an explicit partial-failure result. Add failure-injection
tests where claim delivery and each profile operation fail after earlier writes
succeed.
- Lifecycle Resource Cleanup:
Check `signal?.aborted` immediately after `await this.setValue("mode", newMode)`
and return before `ModeChanged`. Check the signal after each remaining awaited
operation in the mode-switch path, including task-history update, workspace-lock
state post, profile-list write, profile lookup and activation, mode-config
write, and final webview post. Add a regression test that stalls the durable
`viewStates` write past `PENDING_OPERATION_TIMEOUT_MS`, resolves it after
timeout, and verifies that no post-cancellation mode event, profile mutation, or
webview dispatch occurs.

…ting profile save
The activating branch refreshed sibling views inline; the non-activating branch checked only
this.pinnedProfileName, so a save that did not activate left every other live view pinned to
that profile serving its buffered copy of the old settings, and left any task following the
profile with the handler built from them. That branch is load-bearing: handleZooCodeCallback
routes non-active Zoo Gateway profile updates through it.
refreshSiblingsAfterProfileSave is ported unchanged from the n4 head (877ea0a) rather than
invented a third time: one overlay loop over the instances pinned to the saved name, then a
separate task loop. The separation is itself the second half of the fix - the inline copy on
this head nested the task rebuild under the same pinned-name check, so a task restored from
history that follows profile A inside a view pinning profile B was never rebuilt. Both save
branches now call the one helper. ClineProvider.ts 6442 -> 6456 lines.
Tests. The existing sibling case drove activate=true while its comment described the false
branch, so it is renamed to say "pinned to the activated profile" and its comment corrected.
Two cases arrive with the capability: the same save with activate=false, asserting the pinned
sibling's buffered overlay moves to the saved settings; and a sibling whose task follows the
saved profile while its view pins another, asserting the handler rebuild still happens. Both
fail against 723c363 (expected undefined to deeply equal { apiProvider: 'anthropic', ...1 };
expected "vi.fn()" to be called with arguments [ ...2 ]).
Controls (ClineProvider.ts snapshotted at ff22c45, restored by content hash after each):
drop the non-activating call -> the overlay and task cases fail, the activating case passes;
drop the activating call -> only the activating case fails; nest the task rebuild back under
the pinned-name check (the shape this head had) -> only the task case fails; delete the
helper's overlay write -> both overlay cases fail.
Gates: prettier --check clean; tsc --noEmit -p . clean; eslint --max-warnings=0 clean on both
files; vitest core/webview + core/config 44 files / 1301 tests green (1299 before, +2 cases).
Scope 810 -> 815 extension-package executable lines (types unchanged at 8).
…opped
This commit touches one file: src/core/webview/__tests__/ClineProvider.spec.ts.
The two upstream/main merges on this branch (61189bb, d46d7b2) resolved that
file toward our side and dropped 72 declarations that main carries at e943530 -
the whole "webview heartbeat watchdog" suite (70 declarations, 1,912 lines) plus
two top-level .each tables (the diagnostics-broker router and the dev-server probe
fallback). An AST title inventory over all 932 spec files in this tree finds none
of the 72 anywhere else, and no distinctive token from any of their bodies appears
in another spec, so this is deleted coverage rather than a rewording. The four
sibling heads (Zoo-Code-Org#2226, Zoo-Code-Org#2227, Zoo-Code-Org#2236, Zoo-Code-Org#2237) each still carry all 72.
All 72 are re-adopted from main: every adopted body is byte-identical to main's
modulo repo prettier formatting, and no assertion is re-pointed to a different
seam. The suite needs harness plumbing this file had also lost, so the commit
restores exactly that and nothing more: the pWaitFor import, the ViewColumn,
getCommands and createWebviewPanel doubles, a showWarningMessage double that
resolves, and the show member on the sidebar and output-channel doubles. Net
effect: 1,996 added / 27 removed lines as git counts the diff in one file (the only
pre-existing line whose text changes is the showWarningMessage double; the other
"deletions" are identical blocks re-paired by the diff), zero executable lines
changed, and no eslint suppression count moved.
Controls: with mockWebviewView.show removed again the explicit-retry recovery case
livelocks and the worker dies at 122s, so that restored double member is
load-bearing rather than cosmetic. Moving WEBVIEW_WATCHDOG_TICK_MS off 60_000 fails
47 of the adopted cases, never registering the watchdog interval fails 57, and
short-circuiting retryWebviewRecovery fails 14. On the unmutated tree all 381 cases
in the file pass, including the 96 re-adopted heartbeat cases and the 6 re-adopted
table cases.
…ck generation guard
_restoreSharedValuesAfterFailedViewWrite gates every key on the per-key write generation the
setter captured. ContextProxy counts only cached global-state writes: secrets go through
storeSecret and pass-through keys straight to the Memento, and neither advances the map, so
those keys are captured with generation 1 and still read 0 afterwards. The guard is never
satisfiable for them, which exempts exactly the keys whose value cannot be compared back
(a secret is not in getValues, a pass-through key is not cached) from the rollback of their
own failed attempt: after a failed per-view write the secret and the durable task history
stay at the value the failed attempt wrote while every other key is restored.
The filter now skips the generation clause for keys the repo's own predicates say ContextProxy
does not count - isSecretStateKey from @roo-code/types and isPassThroughStateKey from
../config/ContextProxy - and keeps it everywhere else. ClineProvider.ts 6456 -> 6464 lines.
Tests (three cases, all red before the change).
- a secret key (nanoGptApiKey) written alongside a counted key with the per-view write
failing: asserts the store moved to the new value and the cache is back to the old one;
failed with expected 'new-secret' to be 'old-secret'. storeSecret is fire-and-forget, so the
attempted value is asserted by presence, not order.
- a pass-through key (taskHistory) in the same shape: asserts the Memento was written the new
history and then the old one; received only the new write before the fix. The double delegates
to the real store, because replacing it would also silence the read-back the guard compares.
- the guard's own case: a concurrent provider re-writes the very value the attempt wrote, so
only the generation distinguishes them; asserts the newer write stands. Without the generation
clause it reads expected 'architect' to be 'code'.
Controls (ClineProvider.ts snapshotted at 8a5977a, restored by content hash after each):
drop the exemption (the previous guard) -> the secret and pass-through cases fail and the
other three pass; delete the generation clause -> only the same-value case fails, so the guard
is still load-bearing for counted keys; delete only the secret arm -> only the secret case
fails; delete only the pass-through arm -> only the pass-through case fails.
Gates: prettier --check clean; tsc --noEmit -p . clean; eslint --max-warnings=0 clean on both
files with no suppression count changed; vitest core/webview + core/config 44 files / 1304
tests green (1301 before, +3 cases). Scope 815 -> 818 extension executable lines (types 8).
…g rows
CodeRabbit's point measured rather than argued. The two it.each rows share the store order
["Zoo Gateway", "Other", "Zoo Gateway 2"], so only one of them can ever fail
expect(...).not.toContain("Other"): with the stale profile first the every-profile loop breaks
before it reaches the non-gateway profile, so that row cannot observe the filter at all.
Mutants run against 27a2836, production untouched (blob 8a5977a, restored by content hash
after each):
- drop the provider filter in ensureZooGatewayProfileSeeded: fixture as shipped -> 1 of the 2
rows fails (expected [ 'Zoo Gateway', 'Other', ...1 ] to not include 'Other'); with "Other"
leading the store -> both rows fail. The assertion goes from one-row to two-row coverage.
- check only the first gateway profile (the bug the comment describes): 1 row fails on the
handleZooCodeCallback assertion, before and after the reorder, so the reorder does not weaken
the detection this fixture pair exists for.
- no mutant: 397 tests in the file pass.
Test-only: the store order of the two rows moves and the comment records why "Other" leads.
No assertion was added, weakened or deleted - nothing deleted here, duplicate or coverage - so
the number a maintainer needs is 0 deleted-duplicate, 0 deleted-coverage, 1 assertion made
load-bearing in a second row. Gates: prettier --check, tsc --noEmit -p . and eslint
--max-warnings=0 clean; vitest core/webview + core.config suites 44 files / 1304 tests green.

…when it fails
This branch had no write guard at all. There was no reset flag, storeSecret() had nothing telling it a
reset was in progress, and resetAllState() cleared the two caches, deleted every global-state and secret
key in a single Promise.all and reinitialized - the success path being the only path. A save issued while
a reset was still inside its deletes could therefore land after the deletes and put back a value the user
had just erased. This commit introduces the guard, so on this branch the refusal is new behaviour rather
than a repair of an existing one, and it should be read as scope rather than as a bug fix to code that
already refused writes.
What lands: a resetting field, a rejection at the top of storeSecret() carrying the key in failed so a
caller can tell a refused save from a committed one, resetting raised as the first statement of
resetAllState() and lowered in a finally wrapping the whole body. The body itself is untouched: this
lineage has neither a pending-write barrier nor write-owner clears, and importing them from Zoo-Code-Org#2235 would
have imported a different unit's design instead of answering this unit's defect. initialize() performs no
writes, so the refusal cannot make a reset wait on itself.
Two cases, because the guard has two halves and the refusal is the new observable here, so it is tested on
its own rather than as a phase of the leak case:
- refuses a secret write issued while a reset is still inside its delete pass
- accepts a secret write again after a reset whose delete pass rejected
Assertions read captured call arguments (mockSecrets.store.mock.calls filtered on the key) and the cache
and storage read-backs, not toHaveBeenCalledWith: that matcher compares the way toEqual does and drops
undefined-valued keys, so a loose matcher would pass on a tree where nothing is refused at all.
Controls, measured in five steps rather than described. Baseline at e398b67: Test Files 10 passed
(10), Tests 314 passed (314). Refusal case alone with production untouched: 1 failed | 314 passed (315),
AssertionError: expected undefined to be an instance of SettingsWriteError - with no refusal the mid-reset
save simply succeeds. Guard and refusal with the flag lowered only on the success path: 10 passed (10),
315 passed (315). Leak case added against exactly that shape, which is the negative control for the
finally: 1 failed of 316 with the production consequence in the message - promise rejected
"SettingsWriteError: Could not store apiKey: secret writes are refused while state is being reset"
instead of resolving. With the try/finally: Test Files 10 passed (10), Tests 316 passed (316), identical
before and after prettier.
gates: tsc -p . --noEmit exit 0, eslint --max-warnings=0 --no-warn-ignored on both files exit 0, and the
recorded suppression counts for the two touched files stand at 1 and 5 across a --prune-suppressions run;
prettier --check exits 0 on the working copies and 0 on the HEAD copies fed through the same invocation,
so a format failure here would be this commit's. src/eslint-suppressions.json untouched.
Size posture, with the pair printed: scripts/stryker-diff.mjs ci --base
e943530 (main's tip, this PR's recorded base) --head
e398b67 (this commit's parent) exits 1 and puts the
extension bucket at 566 changed executable lines against MAX_CHANGED_LINES 500. This commit
adds 29 added / 14 deleted in src/core/config/ContextProxy.ts plus 69 lines in its spec, and the spec half
is excluded from the bucket by the /__tests__/ segment at scripts/stryker-diff.mjs:85. Stryker itself could
not start locally for either package (spawnSync node_modules\.bin\stryker ENOENT), so no mutants were
scored here and only the size line is a real measurement; it belongs in the PR body or the maintainers'
queue rather than being argued in a commit on a branch declared final.
This ports the answer measured on vps2/n2-viewstates-durability and vps2/n4-values-reset so the three
sibling units do not ship three different answers to one defect. It closes no review row on this PR of
itself.
Mutation-gate measurement for this push, stated here so it is dated and attributed rather than only inside a commit message.
Command and pair, printed rather than recalled: node scripts/stryker-diff.mjs ci --base e943530c848624bd3054c960be1e4fb0b658509a --head <sha> run locally against vps2/n5-ack-history, where the base is upstream/main's tip and this PR's recorded base.
parent e398b6737ddb52513dfe986eb59fdc321537d324: extension bucket 566 changed executable lines against MAX_CHANGED_LINES = 500 (already over the cap before this commit)
head e9ac2639d73a01fa61b6e3541c0a97f8ed4c8cd9: extension bucket 585 changed executable lines
The commit in between answers a reset-guard defect in src/core/config/ContextProxy.ts (+29/-14 there, +69 lines in its spec, which the gate excludes through the /__tests__/ segment at scripts/stryker-diff.mjs:85). So this push deepens a size failure that already existed on #2237 by 66 lines before it, rather than starting one.
Two caveats stated with the number. Stryker itself does not run in this checkout - the script spawns node_modules\.bin\stryker, which is not installed here, so every run exits on spawnSync ... ENOENT and scores zero mutants; the size line above is the only part of the run that is a measurement, and the survivor list for the changed file stays unscored locally. And the CI figure for the same branch is a different number for a different reason than a moved diff, so the two should be quoted with their basis rather than compared as if they measured the same thing.
This is not an argument for writing the guard in fewer lines or adding a Stryker directive: it is the fact that either a narrow maintainer-reviewed exclusion or a split has to answer the size, and it is stated here so nobody has to diff the commit out to find it.
