Split unit N3 of #1546 (view-local buffer reads + setValue persistence)

Third unit of the split plan in the tracking issue (fork issue 41), on top of N2 (#2227).

Scope

• setValue writes the shared value and mirrors it into the in-memory viewLocalState buffer, with _restoreSharedValuesAfterFailedViewWrite rolling the shared write back when per-view persistence fails.
• getValues merges the buffer over the shared values so consumers read the view's own state.
• Focused tests for setValue buffer/rules and failed-write rollback.

Explicitly NOT in this unit

• F0 content (owner: fix(activate): target title-bar commands to their click-origin instance #1528) / F3 content (owner: fix(webview): isolate parallel mode and provider profile writes (vps2 F3) #1560).
• setValues batch persistence and reset/history-restore writes (N4), non-awaiting postMessageToWebview ack (N5).

Budget (own delta vs parent)

• git diff vps2/n2-viewstates-durability..<head>: 149 insertions, 1 deletion (~150 a+d).

Evidence

• ClineProvider.spec.ts: 246 passed; tsc --noEmit: 0 errors.

Stack / merge order

F0 → N1 → N2 → N3 (this PR) → N4 → N5 → F1b → F1c → F3 → F4/F5/F6/F7. Base is main; merge strictly in order.

Refs: #1546, tracking issue 41 (fork).

Summary

Summary by CodeRabbit

• New Features
  • Modes and provider-profile selections are saved and restored independently for each view. Sensitive provider settings are excluded from saved view state.
• Bug Fixes
  • Failed settings writes no longer overwrite newer selections or restore settings cleared by a reset.
  • Deleting a provider profile that doesn’t exist now reports a distinct not-found error.
• Settings
  • View-specific state is omitted when importing or exporting settings.
  • In CLI, history restoration restores modes without activating provider profiles.

The change adds durable per-view mode and provider-profile selections, claim-based view registration, and view-local overlays. It excludes per-view state from settings import and export, adds guarded handling for write and reset races, and introduces a distinct error for deleting a missing provider profile.

Changes: Per-view state

Layer / File(s)	Summary
View-state contracts and settings boundaries packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, packages/types/src/__tests__/*, src/core/config/importExport.ts, src/core/config/__tests__/importExport.spec.ts	The global settings schema validates per-view records, and extension-host messages carry view IDs and claims. Settings import and export omit viewStates.
Write generations and reset ordering src/core/config/ContextProxy.ts, src/core/config/__tests__/ContextProxy.spec.ts	ContextProxy tracks global-state write generations and pending secret writes. Reset waits for pending secret writes and clears write ownership. Tests cover write and reset races and export filtering.
View registration and durable state src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts	ClineProvider assigns view IDs, validates claims, persists and prunes records, and loads eligible mode and profile selections. Tests cover registration, ownership, persistence, pruning, and loading.
View overlays and profile activation src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts	getValues() overlays buffered values on shared settings. Mutations persist before updating the buffer. Profile activation and failed persistence use ownership checks for conditional rollback and refresh affected views.

Provider profile deletion error

Layer / File(s)	Summary
Missing-profile error handling src/core/config/ProviderSettingsManager.ts, src/core/config/__tests__/ProviderSettingsManager.spec.ts	Deleting a missing profile throws ProviderSettingsNotFoundError, which is rethrown without the generic error wrapper. Tests distinguish it from storage errors containing “not found.”

• Zoo-Code-Org/Zoo-Code#2311: Changes ContextProxy handling for overlapping writes and reset races used by conditional shared-value rollback.

Merge Risk: Moderate · up to f95d1

The change adds per-view mode and profile selection. Several rollback and buffer-sync edge cases in rare multi-view or failure scenarios remain open. A failed reset can also let a late deletion erase a secret saved right after it. The required mutation-testing CI check is currently failing and needs a split or a maintainer exemption before merge.

Full details: Title check

Explanation

The title names the core change: setValue writes the shared value and mirrors it into the view-local buffer, and getValues merges that buffer over shared values. The diff adds viewStates types and schema, ContextProxy generation tracking, and ClineProvider view-state persistence and overlays. The title does not mention the wider scope (claims, reset generations, import/export exclusion, and ProviderSettingsNotFoundError), which is acceptable for a title. It is a single sentence, but it is dense and uses internal jargon (N3, split 3/5 of #1546) that a teammate scanning history may not follow.

Full details: Description check

Explanation

The description covers the scope, the explicit exclusions, the stack and merge order, and test evidence. It does not link a GitHub issue using the required 'Closes: #' format; it refers to a tracking issue (fork issue 41) and #1546 instead. The template sections for Test Procedure, Pre-Submission Checklist, Visual Snapshots, Documentation Updates, and Get in Touch are missing or not filled in. The description also does not state a reviewer test procedure beyond the spec run and tsc. It is mostly complete in substance, but several required template items are absent.

Resolution

Add a 'Closes:' line that links an approved GitHub issue, using the template format. Fill in the 'Test Procedure' section with reviewer steps. Complete the Pre-Submission Checklist and the Documentation Updates section. Add a Discord username under 'Get in Touch' if the template requires it.

Full details: Security Boundaries

Explanation

The prior secret leak remains in the changed view overlay path. loadViewState() stores the complete profile returned by getProfile() in viewLocalState.apiConfiguration (src/core/webview/ClineProvider.ts:1034-1041). _viewLocalValuesOverlay() copies every PROVIDER_SETTINGS_KEYS field except keys recognized by isSecretStateKey() (src/core/webview/ClineProvider.ts:4520-4525). vertexJsonCredentials is a service-account credential in the Vertex schema (packages/types/src/providers/vertex.ts:830-836), is included in PROVIDER_SETTINGS_KEYS, and is absent from SECRET_STATE_KEYS (packages/types/src/global-settings.ts:361-398). A view that loads a Vertex profile can therefore expose vertexJsonCredentials through getValues(). API.getConfiguration() returns that view data after applying the same incomplete filter (src/extension/api.ts:626-629).

Resolution

Create an explicit safe projection for view-local overlays. Exclude vertexJsonCredentials, vertexKeyFile, openAiHeaders, and all other credential-bearing fields before storing or returning overlay values, or classify those fields in isSecretStateKey() and apply the filtering consistently. Add regression tests that load a Vertex profile with service-account JSON and verify that both ClineProvider.getValues() and API.getConfiguration() omit the credential.

Full details: Persistence Integrity

Explanation

The changed view-state persistence path still does not reach the webview consumer. setValue() now persists mode/profile selections and getValues() overlays viewLocalState (src/core/webview/ClineProvider.ts:4455-4470, 4489-4528), but getState() still reads contextProxy.getValues() and getProviderSettings() (4197-4207), while getStateToPostToWebview() calls getState() (3949). A reload or a second view can therefore receive the shared mode/profile instead of the persisted view-local selection. The launch producers still send only { type: "webviewDidLaunch" } (webview-ui/src/App.tsx:210, webview-ui/src/context/ExtensionStateContext.tsx:635, apps/cli/src/agent/extension-host.ts:453), and the handler posts state without calling setViewStateId() (src/core/webview/webviewMessageHandler.ts:596-601). This leaves the stable ID and claim path unreachable.

Resolution

Persist a stable viewStateId and host-minted claim in each webview. Include both fields in every webviewDidLaunch message. Handle viewStateClaim in the webview and echo the claim on the next launch. In the webviewDidLaunch handler, await provider.setViewStateId(viewStateId, viewStateClaim) before postStateToWebview(). Update getState() to use this.getValues() and construct apiConfiguration from the view-local provider overlay while retaining shared secret values.

Full details: Regression Evidence

Explanation

The standing concern is only partly resolved. The changed ClineProvider.setValue() path has new coverage, but no focused test covers its success-path shared write, durable viewStates entry, local precedence over a different shared value, and fallback after unset. Changed behavior (src/core/webview/ClineProvider.ts:4455-4491): setValue(key, value) writes the shared value, then mirrors mode and currentApiConfigName into viewLocalState through _saveViewLocalStateFromMutation. On failure it rolls back the shared write. getValues() overlays the local buffer on the shared values. Coverage found in src/core/webview/__tests__/ClineProvider.spec.ts: - Lines 6530-6580: saveViewState tests for mode and currentApiConfigName. They check the buffer and viewStates, but they call saveViewState, not setValue. - Lines 6862-6904: two ClineProvider instances share one ContextProxy. setValue writes mode and currentApiConfigName, and getValues() returns the local values. This covers local precedence over a different shared value, but it does not assert the shared value, the viewStates entry, or fallback. - Lines 7439-7463: setValue(key, undefined) clears the buffer. It asserts only not.toHaveProperty. It does not assert that getValues() falls back to the shared value. - Lines 7483-7505: rollback when the viewStates write rejects. This is the negative path and it is covered. Gaps: - No test reads the shared store after a successful setValue("mode", …) or setValue("currentApiConfigName", …). Shared reads of these keys appear only at lines 6985, 7349, and 7502, all in other flows. A regression that dropped the shared write on success would not fail these tests. - No test asserts getValues() fallback to the shared value after setValue(key, undefined). The standing required resolution asks for one focused test with these assertions. That test does not exist in the current head. The 49 missing-title concern in the objectives was not confirmed: all three describe blocks still exist in the current file and the base. The PR's reported 246 passing tests could not be verified because the sandbox cannot run tests.

Resolution

Add one focused ClineProvider test in the view state persistence edge cases block for a successful defined setValue("mode", ...) and setValue("currentApiConfigName", ...): 1. Seed a different shared value with contextProxy.setValue(key, sharedValue). 2. Call provider.setValue(key, localValue). 3. Assert the shared value equals localValue, since setValue writes the shared store. 4. Assert viewStates[viewId][key] equals localValue (durable entry). 5. Assert viewLocalState[key] equals localValue. 6. Assert getValues()[key] equals localValue. 7. Call provider.setValue(key, undefined). 8. Assert viewLocalState lacks the key and getValues()[key] equals the shared value. Keep the existing rollback test at lines 7483-7505.

Full details: Lifecycle Resource Cleanup

Explanation

The prior lifecycle defect remains in changed view-state paths. savePersistedViewState queues a callback on the static persistedViewStateWriteQueue (ClineProvider.ts:678-755), but dispose() only sets _disposed at line 1453 and does not cancel or invalidate that queue. If a queued saveViewState() is released after disposal, the callback can call contextProxy.setValue("viewStates", ...), then _saveViewLocalStateFromMutation() updates viewLocalState after its await. The new loadViewState() path has the same issue: it awaits custom-mode or profile lookup at lines 1026 and 1038, then checks only viewStateId at line 1049. Disposal does not change that ID, so line 1083 can mutate viewLocalState after disposal. setViewStateId() can also continue after disposal and attempt claim handling. The existing _disposed check in postMessageToWebview() prevents message delivery, but it does not prevent the storage or buffer mutations.

Resolution

Add a provider-scoped disposal generation or cancellation token and advance it at the start of dispose(). Capture and validate it before queued callbacks run, after every awaited operation, before storage or local-state mutation, and before claim delivery. Apply the guard to registration, save, rebind, re-key, clear, and load paths. Add tests that block a queued write and a profile/custom-mode load, dispose the provider, release each operation, and verify no post-disposal storage mutation, buffer mutation, or claim delivery.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Protect live views from recency-only pruning of persisted view selections.

prunePersistedViewStates keeps the 50 entries with the newest updatedAt and does not check whether an entry belongs to an open view. An open view that has not changed its mode or profile recently can lose its entry once 50 other view ids write newer selections. On that view's next reload, its selection is not restored. The provider already enumerates live instances through ClineProvider.getAllInstances(), so live view ids are available at prune time. Exempt those ids from eviction, and make sure the cap does not drop below the live count.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Refresh the sibling views' buffers, or remove the comment that says they are refreshed.

The activation branch refreshes only this provider. The new comment at ClineProvider.ts:2616-2618 says other live views are refreshed, but no code refreshes them. A sibling pinned to the saved profile keeps the old apiConfiguration in its viewLocalState. getValues() returns that buffer, and ExtensionApi.getConfiguration() returns it. The webview state path does not use the buffer, so the stale value does not reach the webview through getState().

Suggested direction

Add a loop in the activation branch that calls _saveViewLocalStateFromMutation({ apiConfiguration: providerSettings }) on each other instance from ClineProvider.getAllInstances() whose pinnedProfileName === name. Then update the comment to match. This direction is not verified against the merge base, and I did not test it.

- Line 141: Strip the host-owned `viewStates` property from `taskConfiguration`
in the `newTask` message path before passing the remaining settings to
`provider.createTask`; retain all other configuration values unchanged so
webview input cannot overwrite durable view state or supply claim tokens.

Review comments at @src/core/webview/ClineProvider.ts:
- Around line 3939-3940: Update resetState to call _clearViewLocalState()
immediately after contextProxy.resetAllState(), so getValues() cannot reapply
stale view-local values after reset.
- Around line 3939-3940: Update getState() to merge viewLocalState into the
values it builds so restored per-view selections reach posted webview state and
task setup when no current task overrides them. Add a test confirming two views
can retain different modes.
- Around line 1027-1033: Restrict the `saveViewState` generic to the supported
keys `mode`, `currentApiConfigName`, and `apiConfiguration`, so unsupported keys
such as `writeDelayMs` are rejected by the compiler.
- Around line 3939-3943: Update setValues in ClineProvider so successful writes
also refresh matching entries in viewLocalState, keeping getValues consistent
with the latest settings after mode changes or task configuration updates.
- Around line 3923-3930: Update the rollback flow around
_saveViewLocalStateFromMutation so _restoreSharedValuesAfterFailedViewWrite does
not overwrite a shared value changed by a concurrent provider. Restore the prior
value only if the current shared value still matches the value written by this
mutation; otherwise leave the newer value intact.
- Around line 2596-2599: Update activateProviderProfileUnlocked to write the
activated profile name through setValue for currentApiConfigName instead of
writing only to ContextProxy, so the viewLocalState buffer reflects the newly
activated profile.

- Around line 2984-2987: In persistProviderProfile, update the successful
activation mirror to save both currentApiConfigName and apiConfiguration through
_saveViewLocalStateFromMutation, keeping the view’s selected profile name
aligned with its settings and durable pin. Add a ClineProvider.spec.ts test that
activates a new profile while the view has a prior-profile buffer, then verifies
getValues() and the persisted viewStates entry both name the newly activated
profile.
- Around line 4532-4534: Update resetAllState so clearing the shared store also
clears viewLocalState for every live ClineProvider, not just the provider
executing the reset; use the existing live-instance tracking mechanism and
preserve the current reset behavior.

Failed pre-merge checks:
- Description check:
Add a Related GitHub Issue line that links an approved issue (for example,
Closes: #N). If the approved issue is the fork tracking issue 41, state that
explicitly. Add a Test Procedure section with the commands reviewers should run
(for example, the ClineProvider.spec.ts run and tsc --noEmit) and any manual
steps. Add the Pre-Submission Checklist with each item checked or marked not
applicable. Add the Visual Snapshots, Videos, and Documentation Updates
sections, marking them not applicable where they do not apply. Update the Scope
section to cover the follow-up commits (profile activation mirroring, rollback
ownership checks, and the heartbeat watchdog test re-adoption). Describe the
design trade-offs and the reviewer checks in the Description section. Note the
open scope-check failure and the 49 missing test titles, and state the planned
fix or the maintainer decision needed.

- Regression Evidence:
Add a focused `ClineProvider` test for successful defined `setValue()` on `mode`
or `currentApiConfigName`. Assert the shared value, durable `viewStates` entry,
local buffer, and `getValues()` result. Seed different shared and local values
and assert local precedence. Clear the local fields with `setValue(key,
undefined)` and assert that `getValues()` falls back to the shared values. Keep
the existing rollback test.

- Security Boundaries:
Create an explicit safe projection for view-local overlays. Exclude
`vertexJsonCredentials`, `vertexKeyFile` where appropriate, `openAiHeaders`, and
every other credential-bearing field, or classify them in `isSecretStateKey()`
and apply the same filtering before storing or returning `apiConfiguration`. Add
a regression test that loads a Vertex profile with service-account JSON and
verifies both `ClineProvider.getValues()` and `API.getConfiguration()` omit it.

- Persistence Integrity:
Persist the stable view ID and host claim in the webview. Include `viewStateId`
and `viewStateClaim` in every `webviewDidLaunch` message. In
`webviewMessageHandler`, await `provider.setViewStateId(viewStateId,
viewStateClaim)` before `postStateToWebview()`. Update `getState()` to use
`this.getValues()` and build `apiConfiguration` from the view-local provider
overlay while preserving shared secret values.

- Lifecycle Resource Cleanup:
Add a provider-scoped disposal generation or cancellation token and invalidate
it at the start of `dispose()`. Capture and check it before queued callbacks
execute, after every awaited operation, before shared or local-state mutation,
and before claim delivery. Apply the guard to save, clear, rebind, re-key,
registration, and load paths. Add tests that block a queued write and a
custom-mode/profile load, dispose the provider, release each operation, and
assert no post-disposal storage mutation, buffer mutation, or claim delivery.

2858-2871: The listConfig() suspension still follows the rollback snapshots.

await this.providerSettingsManager.listConfig() still runs inside the Promise.allSettled array, after the snapshots and generations are captured. The earlier thread already reported this remaining gap.

---

2930-2947: The mode-binding restore still checks ownership outside the locked write.

The ownsSharedSelection() pre-check and the separate getModeConfigId/setModeConfig lock acquisitions leave the race that the earlier thread reported. That thread also records the author's deferral.

---

3098-3104: The mirror rollback still has the list-generation and listConfig() snapshot gaps.

The profile-list restore is still gated on the shared-name generation. The snapshot still precedes the awaited listConfig() call. The earlier review thread already reported both gaps.

Clear the buffers of every live view on reset, not only this view's buffer.

resetAllState() clears the shared store, including every view's viewStates entry. The static viewStatesResetGeneration bump also affects all views. This block clears only this.viewLocalState. Other live providers keep their buffered mode, currentApiConfigName, and apiConfiguration. Their getValues() results then show pre-reset selections that a reload drops. This is the defect the comment describes, but in the other views.

Proposed fix

-		this.viewLocalState = {}
+		for (const instance of ClineProvider.getAllInstances()) {
+			instance.viewLocalState = {}
+		}

Measured, and parking it here as the answer to this row. Owner: n-series-threads. Head it was measured against: f3ca33b (#2227), with the merged head f2d4336 read as well.

One run, three counters, all frozen into one assertion object so the numbers cannot be paraphrased (counters incremented inside resetState by probe lines that were reverted immediately after the run; nothing of this is in any pushed tree):

entered: 1        // resetState() was called and executed its first statement
reached: 0        // the line 'for (const instance of ClineProvider.getAllInstances())' was never reached
loopVisits: 0     assignments: 0   // the clear never executed
trappedWrites: 0  // zero assignments to the viewLocalState container on either provider, across the saves and the reset
contentsChangedInPlace: true       // the buffer's contents did change with zero container assignments
bufferResetting: {"mode":"architect"}   bufferOther: {"mode":"architect"}

Which explanation this separates: entered true with reached false means the method returned between its entry and the loop, so placement is not moot - it is the live question. The statement between entry and the loop that can return is the confirmation gate: resetState compares showInformationMessage(...) against t("common:answers.yes") and returns on mismatch. The counters say it returned there. So on this head the reset-time sibling clear has never actually executed in the harness, and I cannot claim either that it works or that the mutation convention defeats it.

The part that is established independently of the harness gap: the container property is never assigned while its contents change (zero trapped writes, contents changed). That is in-place mutation through the buffer object, not replacement. It is why I state the fix shape as a mutation-convention question rather than a position question: a clear that assigns {} into viewLocalState is a different kind of write than the one the class uses to change that buffer, and even once the reset reaches it, an assignment-shaped clear can leave whoever holds the old object looking at a buffer that still has content. The fix has to either mutate the buffer the way its writer mutates it, or clear it where it is written.

Two artifacts recorded so nobody repeats them. (1) The confirm gate is the second time this row has been blocked by a fixture rather than by product: mocking showInformationMessage to resolve the literal "Yes" while the product compares against a translated string produces an early return that looks exactly like a failed fix. (2) In this junction worktree git diff is not evidence: after git checkout stash@{0} -- ClineProvider.ts the file on disk hashed to the stash blob (7f144872da, containing the loop) while git diff --numstat printed empty and HEAD's blob is 8f05e399aa without the loop. Blob hashes are the evidence there, and the earlier negative - emptying the live list changed nothing - was a comparison between two runs of a reset that never reached the loop. That negative is withdrawn.

Row stays open, deliberately: nothing landed, so there is no fix to resolve against. Next measurement, if this row is picked up again, is one assertion - mock the confirmation to resolve with the prompt's own text, and re-run the same three counters; if reached becomes 1 and assignments becomes 186 (the live-instance count at that point) while the buffers still hold mode:architect, then and only then is the mutation convention the thing to fix.

[coderabbitai]

@easonLiangWorldedtech Understood. This row remains open. Nothing landed, and the reported run did not reach the sibling-clear loop. It therefore does not validate or disprove that fix.

The zero container assignments establish in-place mutation during that run. They do not establish a requirement to preserve buffer identity. In the supplied ClineProvider.ts, loadViewState() replaces viewLocalState, and _viewLocalValuesOverlay() reads the current property on each call. A retained reference could show old contents after replacement without getValues() returning those contents.

When this row resumes, the next measurement should:

• Return the offered confirmation action—the third argument to showInformationMessage—not the prompt message or literal "Yes".
• Assert that resetAllState() and the sibling-clear loop execute.
• Read each provider’s current buffer and call getValues() after reset. Keep those checks separate from any captured pre-reset buffer reference.
• Compare loop visits with the measured live-instance count, rather than hard-coding 186.

That separates confirmation-fixture failure, stale test references, and actual post-reset state. The original sibling-buffer concern remains valid in the supplied code; the proposed clear remains unverified.

Minor · Data Integrity & Integration · Quick win

Snapshot the shared values after listConfig() resolves.

activateProviderProfileUnlocked captures sharedValuesBeforeActivation and the expected generations before await this.providerSettingsManager.listConfig(). That await runs inside the Promise.all group. A write to currentApiConfigName from another source during the await bumps the generation. This activation's own write then bumps it again, so the captured nameGeneration no longer matches. If the view mirror rejects, the compensation skips the shared-selection restore, and it skips the profile-list and provider-settings restores that use the same baseline. The shared selection keeps the failed profile while the view buffer keeps the previous one.

Read the profile list first. Then take the snapshot and generations immediately before the shared writes, so the baseline matches this activation's own writes.

Suggested fix

+			const configList = await this.providerSettingsManager.listConfig()
 			const sharedValuesBeforeActivation = {
 				list: this.contextProxy.getValue("listApiConfigMeta"),
 				name: this.contextProxy.getValue("currentApiConfigName"),

Check list ownership before restoring listApiConfigMeta.

A sibling non-activating upsertProviderProfile updates listApiConfigMeta without updating currentApiConfigName. If that write overlaps a rejected activation mirror, the name-only check still passes.

Create an explicit safe projection for view-local overlays. Exclude
`vertexJsonCredentials`, `vertexKeyFile` where appropriate, `openAiHeaders`, and
every other credential-bearing field before storing or returning overlay values,
or classify those fields in `isSecretStateKey()` and apply the filtering
consistently. Add regression tests that load a Vertex profile with
service-account JSON and verify both `ClineProvider.getValues()` and
`API.getConfiguration()` omit the credential.

- Persistence Integrity:
Persist and echo the stable `viewStateId` and host claim in every
`webviewDidLaunch` message. In the `webviewDidLaunch` handler, await
`provider.setViewStateId(viewStateId, viewStateClaim)` before
`postStateToWebview()`. Update `getState()` to use `this.getValues()` and
construct `apiConfiguration` from the view-local provider overlay while
retaining shared secret values.

- Lifecycle Resource Cleanup:
Add a provider-scoped disposal generation or cancellation token and advance it
at the start of `dispose()`. Capture and validate it before queued callbacks
run, after every awaited operation, before storage or local-state mutation, and
before claim delivery. Apply the guard to registration, save, rebind, re-key,
clear, and load paths. Add tests that block a queued write and a
profile/custom-mode load, dispose the provider, release each operation, and
verify no post-disposal storage mutation, buffer mutation, or claim delivery.

3156-3167: The earlier review finding on this snapshot is still open.

The snapshot and the ownership generations are taken before await this.providerSettingsManager.listConfig() on line 3164. A sibling write during that await invalidates nameGeneration and apiProviderGeneration. This activation then writes with later generations. If the mirror rejects, the compensation at lines 3181-3211 skips the restore although this activation made the latest writes. The list restore is also gated on the currentApiConfigName generation, not on the listApiConfigMeta generation.

Await listConfig() first. Take the snapshots and generations immediately before the writes. Gate the list restore on its own generation, as persistProviderProfile does.

---

4592-4592: The earlier review finding is still open: clear the buffers of all live views.

resetAllState() clears the shared store, including every view's viewStates entry. The static viewStatesResetGeneration bump applies to all views. This line clears only this instance's viewLocalState. Other live providers keep their pre-reset mode, currentApiConfigName and apiConfiguration. Their getValues() results then show selections that a reload drops.

Clear the buffer for each instance from ClineProvider.getAllInstances().

Review comments at @src/core/config/ContextProxy.ts:
- Line 759: Update resetAllState() to clear this.resetting in a finally block so
it is restored whether the reset succeeds or rejects, while preserving the
existing reset operations and error propagation. Add a test where secrets.delete
rejects once, then verify a subsequent storeSecret() succeeds.

---

Failed pre-merge checks:
- Regression Evidence:
Add a focused `ClineProvider` test for successful defined `setValue("mode",
...)` or `setValue("currentApiConfigName", ...)`. Seed different shared and
local values, then assert the shared value, durable `viewStates` entry, local
buffer, and `getValues()` local precedence. Clear the field with `setValue(key,
undefined)` and assert `getValues()` falls back to the shared value. Keep the
existing rollback test.

- Security Boundaries:
Create an explicit safe projection for view-local overlays. Exclude
`vertexJsonCredentials`, `vertexKeyFile` where applicable, `openAiHeaders`, and
all other credential-bearing fields before storing or returning overlay values,
or classify those fields in `isSecretStateKey()` and apply the filtering
consistently. Add regression tests that load a Vertex profile with
service-account JSON and verify both `ClineProvider.getValues()` and
`API.getConfiguration()` omit the credential.

- Persistence Integrity:
Persist a stable `viewStateId` and the host-minted claim in each webview, and
include both fields in every `webviewDidLaunch` message. Handle the claim
message in the webview so the claim is echoed on the next launch. In the
`webviewDidLaunch` handler, await `provider.setViewStateId(viewStateId,
viewStateClaim)` before `postStateToWebview()`. Change `getState()` to use
`this.getValues()` and build `apiConfiguration` from the view-local provider
overlay while retaining shared secret values.

- Lifecycle Resource Cleanup:
Add a provider-scoped disposal generation or cancellation token and advance it
at the start of `dispose()`. Capture and validate it before queued callbacks
run, after every awaited operation, before storage or local-state mutation, and
before claim delivery. Apply the guard to registration, save, rebind, re-key,
clear, and load paths. Add tests that block a queued write and a
profile/custom-mode load, dispose the provider, release each operation, and
verify no post-disposal storage mutation, buffer mutation, or claim delivery.

- Around line 784-793: In the reset operation, replace the early-rejecting
Promise.all for global-state and secret deletions with Promise.allSettled, then
rethrow the first rejection only after every deletion settles so the original

Add one focused `ClineProvider` test in the `view state persistence edge cases`

`contextProxy.setValue(key, sharedValue)`. 2. Call `provider.setValue(key,

writes the shared store. 4. Assert `viewStates[viewId][key]` equals `localValue`
(durable entry). 5. Assert `viewLocalState[key]` equals `localValue`. 6. Assert
`getValues()[key]` equals `localValue`. 7. Call `provider.setValue(key,
undefined)`. 8. Assert `viewLocalState` lacks the key and `getValues()[key]`
equals the shared value. Keep the existing rollback test at lines 7483-7505.

Minor · Data Integrity & Integration · Quick win

Wait for every reset deletion to settle before the finally clears resetting.

Promise.all rejects when the first secrets.delete() rejects. The other globalState.update() and secrets.delete() calls can still be pending at that moment. The finally on Line 793 then sets resetting = false, so storeSecret() accepts new writes again.

Failure sequence:

1. A user saves a secret for a key whose reset delete is still pending.
2. The store resolves, and the cache shows the new value.
3. The pending reset delete lands afterwards and erases the stored value.
4. The cache and storage now disagree. The secret is lost on the next initialize() or extension reload, and nothing reports the loss.

This is the ordering limit raised in the Line 759 thread. Commit 48e9bcb39 does not close it.

Fix:

• Replace Promise.all with Promise.allSettled.
• Rethrow the first rejection only after all deletions settle. This keeps the original error, so the test assertion on "keychain locked" still holds.
• Remove Line 791. The finally already clears resetting, so that line is redundant.

Regression test: reject the apiKey delete, and keep a sibling delete (for example openAiApiKey) pending. While that delete is pending, assert that storeSecret("openAiApiKey", ...) rejects with SettingsWriteError. Then settle the pending delete. Assert that resetAllState() rejects with "keychain locked". Finally, assert that a new storeSecret("openAiApiKey", ...) resolves and reads back from both the cache and storage.
