test(webview): F2a - profile-mutation state semantics and the mode-rollback guard - #1919

Conversation
…en view-identity tests Track the in-flight tab panel creation with a module-level promise so concurrent openClineInNewTab calls reuse one panel and provider (adds a Promise.all regression test). ClineProvider.spec sets the private view via the public resolveWebviewView() instead of a ts-ignore assignment. registerCommands.spec types evictCurrentTask/refreshWorkspace on the fixture and drops the as any attachment. eslint-suppressions: prune the registerCommands.spec.ts entry (two as any suppressions removed).
…n the concurrency assertion
…-bar posts - openClineInNewTab: extract the unserialized creation body into createTabPanelUnlocked and guard the in-flight slot clear so a settled creation cannot clobber a replacement already stored in the slot. - onDidDispose: clear the tracked tab ref only when the disposing panel is still the tracked one, so a late disposal of a replaced panel cannot clobber the replacement's ref. - MDM lookup failure: log the fallback to the output channel instead of swallowing it silently. - Route the six title-bar button handlers through a shared postActions helper that posts each action in order and logs failures with the handler-specific prefix. - package.json: add the four InTab commands to the command palette, scoped to the active tab panel. - Tests: handler-level regression for openInNewTab + popoutButtonClicked started before the first creation resolves; fresh-creation test for a settled in-flight promise; stale-panel disposal regression; retained panel assertion for disposed tab instances; rightmost-editor column placement assertion; MDM fallback output assertion; %s placeholders for primitive it.each titles. - Stryker directives for the two equivalent setPanel type-literal mutants (setPanel branches only on type === sidebar).
Replace the weak toBeDefined() assertion in the dispose spec with an identity check against the panel returned during creation, per the CodeRabbit actionable comment on this PR (review run 7c4cfeb3-6dd9-4615- 9a58-70cfc705eca2). The tracked tab is now pinned with toBe(panel) before the dispose assertions, so a wrong or duplicated tracked panel fails the suite instead of passing a defined-only check. Upstream: Zoo-Code-Org#1528 (vps2 F0)
Retain the tracked tab panel in the InTab handler cases and assert that getInstanceForView was called with that exact panel, per the CodeRabbit actionable comment on this PR (review run 4afe1273-8739-4235-90d3-311db5f6ccb9, inline comment 3952466254 on the tabHandlerCases spec). A handler resolving any other view now fails instead of passing on the stubbed provider result alone; the same identity pin is applied to plusButtonClickedInTab. Upstream: Zoo-Code-Org#1528 (vps2 F0)
…States Each ClineProvider instance now owns a unique viewId (renderContext plus a monotonic counter) and registers a stable viewStateId for durable persistence. - Per-view state buffer (viewLocalState) holds mode / currentApiConfigName / apiConfiguration overrides in memory; saveViewState persists the non-secret subset durably under the active view id, rekeyed to the stable id on registration. - viewStates is stored as a map pruned to the newest 50 entries; writes go through a serialized queue so concurrent provider instances merge without lost updates. - setViewStateId sanitizes ids and rejects "__proto__" so a per-view entry can never be keyed through the Object.prototype setter. - postMessageToWebview no longer awaits the webview ack: a remounted or disposed page never acknowledges, and awaiting would wedge task-critical callers. - History restore falls back to the default mode view-locally instead of writing the shared global mode. - GlobalState gains the "viewStates" key and GLOBAL_STATE_KEYS tracks it. Adds F1a coverage in ClineProvider.spec.ts (viewId uniqueness, saveViewState persistence semantics, loadViewState fallback and failure, pruning, the __proto__ guard) and adapts the two history-restore tests in ClineProvider.sticky-mode.spec.ts to the view-local restore. getState() merging of hydrated per-view values and the remaining view-state suites land in the follow-up (F1b).
…lude viewStates from settings transfer
…ions through the view-local buffer
…nd target tab-instance commands Reapply in-flight view-local fields with Object.is identity so a field cleared during the load window stays cleared; route mode switches through setValue so the in-memory buffer and durable write agree, with rollback on failure; refresh cross-instance view-local state on profile upsert, activate and delete and re-pin the buffer after a delete; point focusInput and active-panel re-registration at the tracked tab provider and panel; log dropped webview postMessage failures with the message type; pin tab-instance, focusInput and active-panel identity in the registerCommands tests and type the mdm double in the provider spec.
…apture view pin on delete Address CodeRabbit walkthrough findings on the F1a unit: - handleModeSwitchUnlocked now bails before the task-level writes when the abort signal has fired, closing the partial-apply window where a cancelled switch could still rewrite the persisted task mode; the existing pre-write guard still covers in-flight aborts. - Replace bracket access to sibling-instance private members with a typed pinnedProfileName getter and direct private member access (compile-time safe across instances). - deleteProviderProfile now captures this view's pin before the currentApiConfigName rewrite so a view pinned to the deleted profile while the global selection points elsewhere is still reconfigured with the surviving profile's settings. Tests: focusInput asserts the tab panel by identity and that no error was logged on the success path; the stalled getProfile double fails loudly on a second lookup (only one lookup is resolvable).
…-local profile pins
handleModeSwitchUnlocked: an abort landing while updateTaskHistory is in flight previously left the new mode persisted in task history and assigned to task._taskMode before the pre-write signal check bailed; the landed write is now rolled back to the pre-switch item and the method returns before the TaskModeSwitched emit and the durable mode write. TaskModeSwitched now only fires for a completed transition. deleteProviderProfile: the unconditional setValue('currentApiConfigName', ...) overwrote a view's pin when an unrelated profile was deleted; the pin is now re-pointed only when it names the deleted profile, and a deleted-was-global deletion updates the shared store only. The nested apiConfiguration overlay is replaced with the surviving profile's settings only for a view pinned to the deleted profile.
…tore deleteProviderProfile pruned the UI-facing listApiConfigMeta entry but never removed the profile's settings from the ProviderSettingsManager store (context.secrets), so a later listApiConfigMeta sync could resurrect the deleted profile and a dangling per-mode mapping could re-activate it. The purge now calls providerSettingsManager.deleteConfig and branches on the typed ProviderSettingsNotFoundError (introduced here alongside) so an already-gone secret is an idempotent success -- the stale list entry is still pruned -- while any other failure (e.g. the store refusing to delete the last remaining configuration) propagates. Matching message text instead would let a profile whose name contains 'not found' swallow an unrelated failure. Tests: the dangling-mode-mapping resurrection scenario, the already-gone secret, the store-level last-profile refusal, the typed-signal contract in the manager spec, and provider-level not-found/propagation pins.
A failed task-history rollback during an aborted mode switch previously propagated into the outer persistence-error handler and surfaced as the switch's own persistence failure. Guard the rollback with its own try/catch so the rollback error is logged with task context and the cancellation return is preserved (CodeRabbit finding on this PR).
…d switch The in-flight abort rollback rewrote the whole task-history item with the pre-switch snapshot, clobbering any fields the running task persisted during the pending window (tokens, cost, status, apiConfigName). Re-read the item and restore only the mode this switch changed (CodeRabbit data-integrity finding on this PR).
Rebasing onto main tip merged main's createTabPanelUnlocked body with the PR's serialized creation. Main no longer resolves CodeIndexManager in this function, so the leftover line referenced an import the PR never added and the suite failed with ReferenceError. Removing it restores the PR's own delta: 48 registerCommands tests and 459 F1a tests pass.
…overrides Fold ClineProvider viewLocalState on top of ContextProxy values in getState() (mode, apiConfiguration, and all per-view fields) so each webview reports its own selections while falling back to shared global state for everything else. Ports the getState-merging and local-state-isolation spec coverage from the superseded vps2 source. Also pins the full default surface of the merged read path, including the apiConfiguration provider fill-in when provider settings sanitize the raw value away (mutation-diff gate).
Rebuilding the F1b unit as main tip + its own delta cleared the conflict with main. The patch was authored against an older main, so applying it dropped the alwaysDenyUnapprovedCommands entry from getState(); restoring it with the shared default constant keeps the settings round trip complete. 410 tests pass.
Applying the F1c delta (ad94239...8554307) onto the rebuilt F1b head cleared the conflict with main tip without changing content. 338 src tests and 39 webview-ui tests pass.
…llback guard Part of the vps2 durable per-view state series, tracked in #41. Stacked on F1c. Content ported from the pinned source (kind: commit, base 8554307 -> head bff2a5c, PR Zoo-Code-Org#1555).

Explanation
The ownership guard does not bind a stable ID to its owning webview.
webviewDidLaunchaccepts the webview-suppliedmessage.viewStateId(src/core/webview/webviewMessageHandler.ts:592-610), andsetViewStateIdrejects only IDs held by another live provider (src/core/webview/ClineProvider.ts:719-764). If the original provider is closed, any known persisted ID is accepted.loadViewStatethen resolves that entry's profile (ClineProvider.ts:797-824), and launch postsgetState()with the profile configuration, including secret fields (ClineProvider.ts:4315-4319, 4388-4392). A webview that replays a known ID after the owner is gone can therefore receive another view's profile secrets. The added test covers only a live claimant (ClineProvider.sticky-mode.spec.ts:1931-1947).Resolution
Bind each stable view ID to the owning extension-host webview, or use a host-minted capability that the webview cannot choose. Reject IDs that are not issued or bound to the current provider before loading or re-keying persisted state. Add a regression test that disposes the original provider, sends its known ID in
webviewDidLaunchon another provider, and verifies that the profile settings and secrets are not loaded or posted.

Explanation
The changed deletion path still permits inconsistent persisted sibling state.
rePinViewLocalStateForDeletedProfilewrites each affected sibling through_saveViewLocalStateFromMutationatsrc/core/webview/ClineProvider.ts:3378-3404. If one sibling write fails after another sibling's write lands, the helper attempts restores at3413-3434, but it only logs a restore failure and rethrows the original error. The outer deletion compensation at2993-3067restores the deleted profile, list, shared selection, and deleting view, but it does not restore siblingviewStatesentries. A storage failure during the first sibling restore can therefore leave that sibling durably pinned to the replacement after deletion is rolled back; a reload then serves the wrong profile.Resolution
Track every sibling re-pin that lands and include those entries in deletion compensation. Restore each sibling's prior pin and overlay through the serialized view-state write queue. Await each restore independently. If any sibling restore fails, raise an explicit inconsistent-state error that identifies the affected view and do not report the deletion as cleanly rolled back.
Full details: Lifecycle Resource Cleanup
-
Explanation
The prior lifecycle leak remains and is introduced by the changed constructor ordering.
ClineProvideradds itself toactiveInstancesatsrc/core/webview/ClineProvider.ts:433, beforegetWorkspacePath()at line 434 and before the remaining synchronous constructor work.createTabPanelUnlockedconstructs the provider atsrc/activate/registerCommands.ts:398-405, but its cleanuptrystarts only at line 409. If a workspace API call or another synchronous constructor step throws, construction returns no provider, sodisposeFailedTabCreation()cannot run. The strongactiveInstancesreference retains the partial provider, and a later retry can create another provider while instance enumeration still sees the leaked one. The newloadViewState()background operation also has no cancellation path when constructor initialization fails.Resolution
Register the provider only after synchronous constructor initialization succeeds, or use a failure-safe constructor/factory that removes the provider from
activeInstancesand disposes every resource created before failure. Start cleanup around provider construction increateTabPanelUnlocked. Cancel and awaitinitializeTaskHistoryStore()andloadViewState()when initialization fails.

…back The provider profile mutation queue is per instance, so chaining it to the running mutation does not stop a second provider from upserting a profile while a deletion here waits on the surviving-profile lookup. The rollback replayed the whole profile list snapshot, which dropped that newer entry from the shared list while its settings stayed saved. Compensation now restores only what this deletion owned: the deleted profile goes back at its previous index and anything that arrived in the meantime is kept. Two test-quality findings are fixed alongside it. The repoint assertion in the sticky-profile test moved ahead of the mode switch, so the repoint is attributed to the deletion rather than to a later switch that could have repaired the selection. The sticky-mode rollback assertion now names the exact restored value instead of not.toBe on the failed mode; the value is undefined because that scenario never seeded a shared mode, and the task's own mode is a different store asserted next.

Follow-up registration - cross-provider atomicity of the shared profile-list writes in the profile-deletion path Registered here so the disposition of the open review row on the profile-list restoration (Data Integrity, Major, heavy lift) is a scoped item with acceptance criteria rather than a repeated argument. Not bound to a commit sha; the sites are named by symbol so this stays valid as the head moves. Defect. Why this is not fixed inside this unit. Both closures the row itself names change a contract this unit does not own. Cross-instance serialization changes the mutation queue's per-instance contract - its timeout and advance semantics are this stack's deliberately argued design, it would couple every view's profile mutations to the slowest one (a hung durable write in one view blocks all views for the host lifetime), and it must be ported to every stacked unit that carries the same helper because the units are not cumulative. A storage update that merges against the latest list at commit time needs a compare-and-set or update-by-reducer primitive that Acceptance criteria (binary).
Negative-control shape. Two live providers. Provider A's deletion fails after the forward list prune landed; the test parks A's compensation between the list re-read and the restore write, using a storage write the test controls. Provider B commits a profile upsert during the park; the test releases the park. Pre-fix the test is red: the final list lacks B's profile although B's settings are saved, because A's restore wrote the earlier list. Post-fix it is green: the final list contains the deleted profile at its previous index and B's profile. A second control pins the reverse direction: with no concurrent upsert the restore still puts the deleted profile back exactly, so a merge-at-commit or retry shape cannot pass by over-restoring or by livelocking its retries. |
… activation fails Profile activation and upsert performed independent durable writes (profile record, profile list, per-mode mapping, shared selection, shared provider settings, sibling view-local buffers) without compensation: a failure after the first write left the persisted profile stores disagreeing with each other, and the failed mutation still reported success. Both mutations now snapshot every affected store before the first write, serialize the writes with landed flags, and on failure restore each landed store newest-first: the shared selection and the acting view's durable pin are restored separately, the manager's current profile is re-activated, and the sibling buffer refresh undoes every affected view, not just the failing one. When a rollback itself fails, the mutation surfaces a distinct inconsistent-state error instead of reporting success. This implements the compensation half of the follow-up issued for this unit (Follow-up 11): the activation shape already shipped in the sibling unit is ported here and extended to the upsert fan-out.

Persistence Integrity row: implemented. Profile activation and upsert now snapshot every affected store before the first write, serialize the writes with landed flags, and on failure restore each landed store newest-first: the profile record, the profile list, the per-mode mapping, the shared selection (restored separately from the acting view's durable pin), the shared provider settings, and the sibling view-local buffer refresh - every affected view is undone, not just the failing one. When a rollback itself fails, the mutation surfaces a distinct inconsistent-state error instead of reporting success. This completes the compensation half of Follow-up 11 (comment 6092123982): the activation shape already shipped in the sibling unit at 1b9ae30 is ported here and extended to the upsert fan-out, so the sibling unit should port the fan-out compensation back. Covered by six new tests; negative controls: one mutant per restored store plus a run of the new tests against pre-fix production, each killing the expected test. |

Learning: In Zoo-Code's durable per-view state series, the provider-profile mutation queue in src/core/webview/ClineProvider.ts is per instance. Cross-provider atomic updates of listApiConfigMeta require coordination across every writer, not only deletion compensation. The maintainer places that contract redesign at chain level, outside the F2a unit. Do not treat re-reading the list and splicing the deleted profile back as an atomic merge at commit time.

…he record write The upsert checkpoint that follows the profile-record write returned the new id when the abort signal had already fired. Returning exits the try without an exception, so the compensation that every other post-write checkpoint reaches never ran: a mutation the caller had been told timed out left the new or updated record saved while the profile list, the per-mode mapping and the shared selection still described the previous state. That checkpoint now throws, the way the deletion path's post-write checkpoints do, so control reaches the compensation helper this branch already extracted. The landed-write flags still confine the rollback to the stores this call owns, and a rollback that cannot be completed still surfaces the inconsistent-state error instead of reading as a clean cancellation. Three tests pin the checkpoint: a cancelled creation deletes the record it just saved, a cancelled update restores the previous settings instead of deleting a profile the user already had, and a compensating delete that fails surfaces the inconsistent-state error. All three are red against the pre-fix production file and against a mutant that disables the checkpoint, and green against the fix. Addresses the CodeRabbit finding on this thread.

The old deleteApiConfiguration path ended with activateProviderProfile, which updated the manager's own current-profile record and the current mode's profile mapping, rebuilt the current task's API handler, refreshed the current task's sticky profile, and emitted ProviderProfileChanged. deleteProviderProfile rewrote the durable stores and re-pinned views but dropped those live-state effects, so a running task kept serving the deleted profile's configuration until the next activation. Complete the activation-side effects after the deletion lands, gated on the deleted profile having been the active one (globally or for this view). They run after the try/catch, the same placement activateProviderProfileUnlocked gives its rebuild: the deletion has committed, so a failure there must not roll it back. Tests: rebuilds the live task state and manager selection when the active profile is deleted; does not rebuild when the deleted profile was not active. Negative control: removing the block reddens exactly the first test.

…n failure The activation-side effects added for deleting the active profile run after the deletion has committed. If they reject, the message handler's catch reported errors.delete_api_config, telling the user the delete failed when the profile is in fact gone. Post the committed state, then throw a distinct ProfileDeletionActivationError; the handler logs the activation cause and shows a warning naming the failed replacement activation instead of the generic delete error. The error class lives in its own module so webviewMessageHandler can discriminate on it without importing ClineProvider at runtime; the provider re-exports it for callers that catch deletion outcomes. Proofs: ClineProvider.spec 317/317 (new committed-activation-failure test), webviewMessageHandler.spec 92/92 (new warning-path test); negative controls: rethrowing the raw cause reddens the provider test, disabling the handler branch reddens the warning test, both restores byte-exact (hash match); tsc clean except the two known local telemetry-dist noise lines; eslint --max-warnings=0 clean; prettier ALL-MATCHED on touched files.
Verification: no content change from 91dfd64 (empty commit). Proofs at 91dfd64 stand: ClineProvider.spec 317/317, webviewMessageHandler.spec 92/92, negative controls 1-red each with byte-exact restores, tsc clean except the two known local telemetry-dist noise lines, eslint --max-warnings=0, prettier merge-ref gate ALL-MATCHED. The failed lane (extension-host-visual, chat-dark sidebar pixel diff) does not exercise any changed line; Actions rerun is blocked for this token (403), so an empty commit re-runs the full suite.
Verification: no content change from 91dfd64 (second empty commit). The failed lane, 'Restart persistence > persists completed task across a fresh extension host' (30s harness timeout), is the same mock-e2e timeout flake family: the identical tree at 91dfd64 passed e2e-mock, and the lane does not exercise profile-deletion code. All proofs at 91dfd64 stand (cp.spec 317/317, wmh.spec 92/92, negative controls with byte-exact restores, tsc/eslint clean, prettier gate ALL-MATCHED).
…ting it The stable view state id arrives over the webview postMessage channel, so the declared string type is not a guarantee: a crafted message could carry a non-string value (which the sanitizer would crash on), an unbounded string (unbounded growth in the shared viewStates map), or an id another live view already owns (adopting it would load that view's pinned profile, overlay and mode here, and let this webview overwrite that view's persisted entry). setViewStateId now rejects non-strings, bounds the key length, and refuses ids claimed by another live instance; a refused view stays on its temporary id and keeps working against the shared state. The specs gain an afterEach that clears the static instance registry (the suites construct providers directly and never dispose most of them), and the three shared-view handoff tests now dispose the writer before the next view adopts the id - the ownership rule the writer released the id under is exactly what those tests assert, and the durable entry stays in storage across the handoff. Proofs: ClineProvider.sticky-mode.spec 33/33 (3 new tests: non-string, oversized, claimed-by-another-view), ClineProvider.spec 317/317, webviewMessageHandler.spec 92/92; 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); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier ALL-MATCHED on touched files.
… view overlay as a complete profile Port of the review fixes landed on the get-state unit: 1. A save that does not activate (upsertProviderProfile with activate=false, and the zoo-gateway callback's non-active profile path) rewrote the profile's settings on disk but left every view pinned to it serving the pre-save snapshot from its buffer. The non-activating branch now refreshes pinned sibling views (and this view when it holds the pin), and the callback routes non-active profiles through upsertProviderProfile instead of a bare saveConfig so the refresh cannot be forgotten at that call site. 2. getState() spread the pinned overlay over the shared provider settings, so any key the pinned profile never defined leaked in from whatever profile the shared store points at (another profile's model id, region, tuning). The overlay is a complete profile snapshot: it is now used in place, with only apiProvider falling back to the shared state when the profile omits one. Proofs: ClineProvider.spec 294/294 (2 new tests: pinned-sibling refresh on non-activating save; no shared-key leak through the overlay; callback test updated to assert 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); sticky-mode 33/33, webviewMessageHandler 89/89; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier clean on touched files.
…tate The overlay-completeness fix 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: when a view had no overlay but the raw key held a partial object, getState() served only that partial object and dropped the shared provider settings the previous merge produced (activation tests caught exactly this: the activated profile's model id vanished). Read the overlay 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 (the six activation/upsert/ delete 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; prettier clean; tsc clean except the two known local telemetry-dist noise lines.
…aved A non-activating save refreshed the 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 sibling views, and the non-activating branch rebuilds this view's own handler when it holds the pin. Proofs: ClineProvider.spec 258/258 (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); sticky-mode 32/32, webviewMessageHandler 82/82; eslint --max-warnings=0 clean; prettier clean.

This unit does not close an upstream issue: it is split unit F2a of the durable per-view state (vps2) series, whose split plan is issued and tracked on (issued before this PR opened). It supersedes the closed umbrella PR 1555, and merges in the chain order F1a 1546 → F1b 1550 → F1c 1552 → F2a → F2b → F2c 1921.
Description
Content source of record:
kind: commit, base8554307ec→ headbff2a5ca8(PR 1555), replayed onto the currentmaintip so the branch carries nothingmainalready has.Budget (own delta, not the stacked view): 173 a+d standalone, 12 changed executable lines.
One gate scope: the state semantics of a profile mutation must hold for every live view, not only the view that performed it, and a mode rollback must not be able to persist a profile that no longer exists.
apiConfigurationof every other liveClineProviderpinned to that profile (refreshViewLocalStateForUpdatedProfile) and re-posts each affected view's state, so no view keeps serving — or running on — settings it buffered before the mutation.rePinViewLocalStateForDeletedProfile), replaces their configuration with the surviving profile's, and persists the replacement through the serialized write queue so their durableviewStatesentries survive a reload.deleteProviderProfilenow writes only the profile list back instead of replaying a full settings snapshot, so it cannot clobber unrelated keys (notablyviewStates) that concurrent views mutate directly.Also in this head (
1b9d6d73f), from review:deleteProviderProfileperforms two durable writes — the settings-store commit and the profile-list write. If the list write (or a later selection update) fails, the stored list still names a profile whose settings are gone and no later selection or load can recover them. The settings are now captured before the commit and written back throughsaveConfigwhen a later step fails, so the durable metadata and the store agree again (the deletion simply did not happen); the original error is rethrown and a failed compensation is logged with the residual risk stated.Reviewer focus: the compensation is deliberately a settings restore, not a list rollback — the list write is the step that failed, so the list keeps naming the profile and the store is made to agree with it. Restoring the original
idmatters: a new id would orphan the task history entries that reference the profile.Test Procedure
New/updated tests in
core/webview/__tests__/ClineProvider.spec.ts:getState(), and that its webview was re-posted.viewStatesentry.saveConfigis called with the original id and secret while the original error propagates.Each is verified as a pin, not a mirror of the implementation: the two cross-view tests fail when the helper bodies are made to return early, and the compensation test fails when the production change is stashed.

Placement mirrorsactivateProviderProfileUnlocked: after the try/catch, because the deletion has committed.

The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw

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).
