fix(core/webview): merge view-local state into getState for per-view overrides - #1550
Part of the vps2 durable per-view state series — tracked in fork issue 41 (cross-repo: the displayed vs-main diff includes the F1a content this unit branches from until F1a merges).
Fix unit F1b (2/3 of the F1 split). F1a landed per-view identity, the durable viewStates pipeline, and the in-memory viewLocalState buffer, but getState() still read every field straight from the shared ContextProxy — so a webview reporting state ignored its own hydrated per-view selections. This PR:
getState() merge — mergedStateValues = { ...contextProxy.getValues(), ...viewLocalState }; every per-view-capable field (mode, currentApiConfigName, apiConfiguration, modeApiConfigs) is served off the merge: a view-local selection beats the shared global value, unset fields fall back to the shared value with existing defaults untouched. apiConfiguration re-merges over the shared profile settings so the flat provider-settings mutation path stays coherent. The read path stays side-effect free.
F1a shared-code fixes ported in (this round): temporary-id ownership (wroteUnderTemporaryViewStateId — first write claims the slot, load and re-key only touch entries this instance authored, authorship recorded only after the durable write lands), shared-write rollback in setValue / setValues when per-view persistence fails, and the null-prototype copy in getPersistedViewStates.
Spec coverage — the getState-merging and local-state-isolation describes, the ported F1a regression tests (ownership, rollback), and the default-surface pinning tests.
The webview launch-identity wiring that registers stable ids (F1c) lands in the follow-up.
Content source
Hand-ported from CS e9a44b2fa (fork PR 43 head): the getState merge hunks and the getState-merging spec describes; the F1a snapshot on this branch carries the same review-round fixes as the F1a PR head (ported this round, with two tests adapted to the ownership semantics).
Budget
a+d vs merge-base 89a90f513: 5435 (+5025/−410) — includes the shared F1a content until F1a merges; the F1b-specific delta is the getState() region in ClineProvider.ts (~104 executable lines) plus spec coverage. Over the 400 soft budget; split decision belongs to maintainers.
How to test
pnpm --dir src exec vitest run core/webview/__tests__/ClineProvider.spec.ts core/webview/__tests__/ClineProvider.sticky-mode.spec.ts activate/__tests__/registerCommands.spec.ts
Manual: two views with different modes; the webview of each view reports its own mode/profile in state messages instead of the shared selection.
Verification numbers
eslint --max-warnings=0 on all changed files: pass; suppression counts never increased (ClineProvider.spec.ts 196→194 re-measured, ClineProvider.ts 7, sticky-mode.spec.ts 26, registerCommands.ts 1).
vitest: ClineProvider.spec + sticky-mode.spec + registerCommands.spec 362 pass; sticky-profile + taskHistory + ContextProxy + importExport specs 191 pass (3 ProviderSettingsManager migration tests fail locally only — they read a types constant the stale local types build lacks; CI builds types from source).
tsc --noEmit: no new real errors (all local errors are the stale-types class; CI builds types from source).
Negative control on the ported ownership fix: reverting the first-write claim reddens exactly the ported regression test; restored byte-exact (sha256 match).
prettier --check on the full merge-ref tree (LF-normalized): pass.
mutation-diff advisory: extension package 638 changed executable lines (limit 500) — inherited from the shared F1a content on this branch, not new in this unit; maintainer decision.
Updated this round
Merged upstream/main (conflicts in registerCommands.ts, ClineProvider.ts, and both spec fixtures resolved keeping both sides; constructor call sites gained the webviewFocusTracker argument).
Ported the F1a review-round fixes into the shared per-view code (ownership, authorship-after-persistence, setter rollback, null-prototype map) with the regression tests; adapted two pre-existing tests to the ownership semantics (register a stable id before forcing a load failure; author the temporary entry through the real write path before re-key).
eslint-suppressions re-measured; PR body rewritten.
Security Boundaries / view-state id rows: addressed at 8c9c55f. setViewStateId now rejects non-string ids (crafted postMessage), bounds the key length (MAX_VIEW_STATE_ID_LENGTH), and refuses ids already owned by another live instance; a refused view stays on its temporary id against shared state. Regression tests: non-string, oversized, claimed-by-another-view. Negative controls: disabling the ownership check reddens exactly the claim test; widening the length bound reddens exactly the oversized test; restores byte-exact (hash match).
Persistence Integrity setValues/setValue ordering rows: verified already addressed by the pushed code: _saveViewLocalStateFromMutation persists the non-secret subset before updating the buffer; the re-key is a single queued write (no delete-then-write window; authorship clears only after the write lands); the mutation hook keeps the buffer synced across setValue/setValues and profile upsert/activation/deletion.
Proofs at 8c9c55f: sticky-mode 33/33; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Non-activating saves (upsertProviderProfile with activate=false, and the zoo-gateway callback's non-active path) rewrote the profile on disk but left pinned views serving the pre-save snapshot; the non-activating branch now refreshes pinned sibling views (and this view when it holds the pin), and the callback routes through upsertProviderProfile so the refresh cannot be forgotten.
getState() no longer spreads the pinned overlay over the shared provider settings (a key the profile never defined leaked in from the shared profile: model id, region, tuning). The overlay is a complete snapshot: used in place, with only apiProvider falling back to shared state.
Regression tests: "refreshes views pinned to a profile saved without activation"; "does not leak shared provider keys into a pinned view's api configuration; the zoo-gateway callback test asserts the upsert path.
Negative controls: dropping the else-branch refresh reddens exactly the refresh test, reverting the merge semantics reddens exactly the leak test; restores byte-exact (hash match).
Proofs at e0e540e: ClineProvider.spec green, sticky-mode and webviewMessageHandler green, eslint --max-warnings=0 clean, tsc clean except the two known local telemetry-dist noise lines, prettier merge-ref gate ALL-MATCHED.
Follow-up: overlay read from the view buffer (required-lane fix)
The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw apiConfiguration state key. That key is a partial patch written by shared-store paths, not a view snapshot: with no overlay present and the raw key partial, getState() served only the partial object and dropped the shared provider settings the previous merge produced (the parallel-mode activation tests caught exactly this - the activated profile's model id vanished; required lane red on the units carrying that spec). The overlay is now read from the view buffer itself, where a present value is by contract a complete profile and an absent one means the shared store serves the settings.
Proofs: ClineProvider.parallelMode.spec green where present (the six synchronization tests that regressed), ClineProvider.spec green including the overlay-completeness tests, sticky-mode and webviewMessageHandler green; negative control: reverting the overlay to a shallow merge over the shared settings still reddens exactly the leak test; restores byte-exact (hash match); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Follow-up: active task handlers rebuilt on non-activating saves (head 08af5cb)
A review round on the view-identity unit found that the non-activating-save refresh updated pinned views' buffers but not their active tasks' API handlers, and the posted state prefers the task's own apiConfiguration: a conversation running in a view pinned to the saved profile kept sending the old token (e.g. after the Zoo Gateway callback rotated it) even though the view's buffer had caught up. The refresh now rebuilds the affected tasks' handlers in the pinned views, and the non-activating branch rebuilds this view's own handler when it holds the pin.
Proofs: ClineProvider.spec green (the pinned-sibling refresh test now asserts the active task's handler is rebuilt with the saved settings, not just the private buffer); negative control: dropping the rebuild from the refresh reddens exactly that assertion, restores byte-exact (hash match); parallelMode/sticky-mode/webviewMessageHandler green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Follow-up: test-quality round from the review (head ef73863)
The review round on the api-wiring unit named four test-quality issues; the ones present in this unit are fixed here: the viewStates describe block moved out of the alwaysDenyUnapprovedCommands block (test names carried the wrong subject), the prune test's toBeDefined() survival checks replaced with exact-shape toEqual assertions (they pass even if pruning strips fields), the stale-temporary-entry test's fixed 10 ms wait replaced with awaiting the load itself (the negative assertion could pass vacuously on a slow load), and the readiness-cancel test's fake timers restored in a finally block (a failed assertion left fake timers active and hung a later real-timer test).
Proofs: global-settings 9/9 where present, ClineProvider.spec green, sticky-mode green where present, api-task-control green where present; negative controls: pruning that strips updatedAt reddens exactly the prune test, a loadViewState that adopts the unowned temporary-id entry reddens exactly the stale-entry test, restores byte-exact (hash match); eslint --max-warnings=0 clean (src and types); prettier merge-ref gate ALL-MATCHED.
Follow-up: review-round fixes from the series (head 6efdad3)
A review round on the mode-profile-writes unit found that the profile-deletion re-pin updated each sibling view's buffer but not its running task: the posted state prefers the task's own apiConfiguration, so a conversation in a view pinned to the deleted profile kept sending the deleted profile's settings. The re-pin now rebuilds the sibling's API handler with the replacement's settings and re-points the task's sticky profile name, mirroring the activation path.
Proofs: ClineProvider.spec and sticky-mode green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED. The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.
Updated this round (CodeRabbit follow-up, head 50aa367)
Non-activating profile saves no longer force-rebuild the API handler of a view whose active task follows a different sticky profile: both rebuild sites are guarded by taskApiConfigName === saved profile; pinned-view overlays still refresh. Regression tests cover both sites (negative control: removing either guard reddens exactly its test).
Test hygiene: prune assertions compare full kept entries; the two re-key storage tests seed viewStates through the durable write path so their assertions can fail.
Updated this round (CodeRabbit follow-up 2, head 66f5945)
Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite now require taskApiConfigName === deleted profile (the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test).
Per the AGENTS.md policy (never add Stryker directives; remove them when a file is touched), all // Stryker disable directives were dropped from this PR. Equivalence rationale for the removed suppressions:
Stryker disable next-line ConditionalExpression: defensive clobber guard, unreachable per the ordering argument above.
Stryker disable next-line StringLiteral: setPanel branches only on type === "sidebar", so any other literal routes to the identical tab-ref assignment
Stryker disable next-line StringLiteral: setPanel only distinguishes "sidebar"; any other value routes to the tab-ref assignment
Activation writes from the stored record: upsertProviderProfile reads the saved profile back after saveConfig and builds the shared provider-settings write, sibling refresh, view overlay and task-handler rebuild from the normalized record, so raw webview fields the profile schema strips cannot enter durable state (CR Security Boundaries).
Clear/re-point cache rollback: clearPersistedViewState and repointPersistedViewStates restore the in-memory viewStates cache to the value durable storage actually holds when the durable write rejects, before rethrowing (CR Persistence Integrity).
Activation rollback completeness: the pre-activation snapshot now captures the exact durable viewStates map and the rollback restores it through the serialized queue, so a sibling entry evicted by the activation's own pruning is not lost (CR Persistence Integrity).
Deletion re-points closed views: deleteProviderProfile now calls repointPersistedViewStates so disposed views' durable pins follow the surviving profile (CR Persistence Integrity).
Verification: new tests are focused negative controls (reverting each guard reddens exactly the matching test); ClineProvider.spec, webviewMessageHandler.spec spot-checks, api specs, spec-inclusive tsc --noEmit, eslint --max-warnings=0 (suppression counts unchanged) and prettier all green on this head.
Merged the current upstream/main (merge commit; the row-9 fix commit is unchanged and is the first parent) to clear the review gate's mergeability hold. Upstream refactored upsertProviderProfile into a new persistProviderProfile method and added a runToCompletion queue option; this unit's transactional body was ported into the new method unchanged and upstream's Promise.allSettled activation fix was adopted in it. ClineProvider.spec, webviewMessageHandler.spec, tsc --noEmit, eslint (suppression counts unchanged) and prettier re-verified green at this head. The first refreshed head's windows unit-test lane caught that upstream's new updateProfileModel tests in ClineProvider.apiHandlerRebuild.spec.ts mock the settings manager with a static getProfile, which starves the post-save read-back; the mock now repoints getProfile at what saveConfig wrote (the real manager's behavior), and the file's 38 tests pass locally alongside the rest of the verification set.
Review round r111 - threads 1 and 3 (702913278)
Test-only commit, one push, on top of e0cb48c51 (no fork-side commits were lost: e0cb48c51 is its parent, and git log confirms the fast-forward chain).
Majorrt4473642023webviewMessageHandler.spec.ts:2747-2753: the rename-compensation ordering assertion compared findIndex results from two different mocks, which cannot order the events. Kept the indices to select the calls and compared mock.invocationCallOrder values, the shape the deleteCustomMode test already uses. Proven to have teeth by hand-hoisting the compensation restore above the delete: the old assertion stayed 139/139 green, the new one reddened (expected 549 to be greater than 550), and with the mutation reverted both lanes are green.
Trivialrt4473641992ClineProvider.sticky-profile.spec.ts: the retained-survivor test asserted names only. Seeded the shared provider settings through contextProxy.setProviderSettings (the call an activation makes) with the survivor payload and asserted the payload now paired with the survivor name. Teeth proven against a planted deleteProviderProfile write that pairs the deletion's own first-survivor pick with the shared store: seeded assertion reddened (expected gpt-4.1 to be gpt-4o), the names-only version stayed 25/25 green under the same planted write.
Both threads answered in-thread (discussion_r4476882830, discussion_r4476883074) and resolved. rt4473642091 (Minor, the deleteCustomMode compensation) is untouched here: it needs a behaviour change in webviewMessageHandler.ts plus the upstream/main conflict resolution in ClineProvider.ts, and is being handled separately.
Verification at this head: tsc -p tsconfig.json --noEmit exit 0; eslint --prune-suppressions --max-warnings=0 clean on both touched files; eslint-suppressions.json byte-identical to e0cb48c51 (3302 total, no increase); prettier no-op; pre-commit and pre-push hooks ran (no --no-verify); committed-blob lane runs - webviewMessageHandler.spec.ts 139/139, ClineProvider.sticky-profile.spec.ts 25/25. Local vitest lanes skip pretest bundling, so bundle-dependent specs stay CI-only. No changeset and no CHANGELOG entry.
Conflict state, measured rather than read from base.sha (the REST list reports the stale 3ee042d91; upstream main is e943530c8 and merge-base confirms this branch carries an older main): a trial git merge --no-commit --no-ff of e943530c8 auto-merged 73 modified and 39 added files and left exactly one conflicted file, src/core/webview/ClineProvider.ts, in three hunks - the import block, the state-posted field list (this side renamed stateValues to mergedStateValues while main added timeFormat/dateFormat/showRelativeTimes to the same block), and the setValues/_saveViewLocalStateFromMutation region (143 rewritten lines against main's 4). Trial merge aborted; nothing was committed from it.
Review round 2 - thread 1 only (09a0313c3)
CodeRabbit re-reviewed 375e25546 and left five live threads. Thread 1 (rt4477271587, src/activate/__tests__/registerCommands.spec.ts) is closed here: plusButtonClicked focuses the sidebar pane and waits for the view only when the provider has no view yet, and no test reached the launched branch - the shared mockProvider double never defines isViewLaunched and the gate test sets it to false. The added test pins the launched branch (no SidebarProvider.focus, no whenViewResolved, both actions still posted in order).
Controls measured on the implementation at 375e25546: baseline 59/59; unwrapping if (!provider.isViewLaunched) so focus and the wait run on every click leaves the suite without the new test green at 59/59 and reddens exactly the new test with it (1 failed of 60); deleting the guarded block (never focus) reddens the existing gate test instead. Committed text: 60/60, eslint clean with no suppression entry on the file, eslint-suppressions.json unchanged at 3298 total, tsc --noEmit exit 0.
The other four threads (rt4477271618 dispose flush, rt4477271629 activation mode-mapping capture, rt4477271636 rename read-back ownership, rt4477271646 delete-profile lookup source) are behavioural claims about write paths. They were re-measured against 375e25546: the rename one already carries the ownership check and its test; the delete one names a method (syncProviderList) that does not exist in src; the mode-mapping rollback is already tested (ClineProvider.spec.ts:6623/6637, 6948/7003); the dispose flush trade-off is real and the tests that pin it are ClineProvider.spec.ts:4862-4865, 4882, 4894-4896, 4918, not the files the review cites. They are with the maintainer for disposition, so no reply was posted on them yet.
CI at this head is not green: the org commit view carries the reconcile and resolve bookkeeping checks with CodeRabbit skipped and no pull_request lanes; the fork commit view carries none. Per the campaign rule, no lanes is not a pass.
Review round 2 - threads 2 and 3 (a63981380)
Thread 2 (rt4477271618, dispose flush). Measured before changing anything: nothing at launch drops temporary-id entries - nextViewId is declared at ClineProvider.ts:325 and consumed at 587 and nothing else recognises the shape - while loadViewState (1144) refuses to read such an entry back and prunePersistedViewStates (1044) sorts newest-first and slices MAX_PERSISTED_VIEW_STATES (326). The dispose write therefore stored a record nobody can load, at the cost of a slot that outranks loadable entries at eviction. Teardown now drops the held change and the forceUnregisteredWrite option goes with its only caller. The flush-asserting test is replaced by one asserting the change is dropped and nothing reaches storage; the test whose subject was a teardown flush that fails is deleted. Control: against the previous provider the replacement test fails with expected { 'sidebar-293': { ...(2) } } to deeply equal {}.
Thread 3 (rt4477271629, mode mapping compensation). The previous activationMode was a function-local with a single assignment, so a mode change inside the window did not retarget the rollback; the real gap was the gate - the sibling snapshot at 3424 is awaited before the mapping write is issued, so a failure there replayed setModeConfig(mode, undefined) and cleared a mapping the call never touched. The rollback is now gated on and replayed from a record created when the write is issued (3435, gate 3508). Tests: the pre-issue case fails on the previous code (setModeConfig called once when it should not have been called at all); the two mid-window tests (mode set after capture, shared mode cleared after capture) pass unchanged today and their control - a rollback that reads the live mode - reddens them together with the existing rollback test.
Lanes on the committed text: ClineProvider.spec.ts 474 passed (baseline at 375e25546 was 472), webviewMessageHandler.spec.ts 174, ClineProvider.sticky-profile.spec.ts 25, ClineProvider.sticky-mode.spec.ts 29. eslint --max-warnings=0 exits 0 on both touched files, eslint-suppressions.json is unchanged at 3298 total, tsc --noEmit exits 0, prettier is a no-op on the committed text. The sibling-snapshot helper family also carries sharedStoreCarriesProfileRecord on vps2-f2a (2b7a41d58) and vps2-f2c (e8b2ac051); this branch does not carry that predicate and this head does not add a third version of it.
Threads 4 (rt4477271636) and 5 (rt4477271646) were answered with measurement and resolved without a code change: thread 4 asks for an ownership check that already runs on the path it names (removeOwnRenameRecord, webviewMessageHandler.ts:2563-2574, exercised by webviewMessageHandler.spec.ts:2791-2827), and thread 5 would make a derived mirror authoritative for an operation that works on the manager record, with provider.syncProviderList() not existing anywhere in src.
Four review rows parked on #1550 as owner. Each was measured against a639813 before deciding, then answered in-thread.
discussion_r4413244726 (feat(webview): view-local buffer reads and setValue persistence (N3, split 3/5 of #1546) #2235, packages/types/src/global-settings.ts:136) - fixed here. setValues now drops a caller-supplied viewStates map before the shared write and logs it; the generic updateSettings loop writes through ContextProxy directly (webviewMessageHandler.ts:894), bypassing setValues, so it drops the same key before any side effect is run for it. Both doors are caller input only: the provider rewrites the registered map through contextProxy.setValue itself (ClineProvider.ts:858, :898, :960), no host caller passes viewStates to setValues, and webview-ui never sends it at all (0 hits), so this is hardening against a crafted message - but a crafted map really did replace every other view's entry, which is why it was fixed rather than left open on trust. Two claims in that row are not on this tree: claimToken has 0 occurrences in src + packages, and the handler's only provider.setValue callers pass defaultModeSlug (webviewMessageHandler.ts:2912, :2924), so no third door needed.
discussion_r4413249695 (feat(webview): view-local buffer reads and setValue persistence (N3, split 3/5 of #1546) #2235) and its twin discussion_r4413254574 (feat(webview): setValues batch persistence and reset cleanup (N4, split 4/5 of #1546) #2236) - already shipped at this head. resetState clears the buffer (contextProxy.resetAllState() at :5724, then _clearViewLocalState() at :5727, with the live-sibling fan-out at :5741), so the method is not uncalled here; getState() overlays the buffer (mergedStateValues = { ...stateValues, ...this.viewLocalState } at :5209, consumed for the provider at :5216 and through the returned object), getValues() merges the same way at :5541-5543, and the restored apiConfiguration is resolved during loadViewState (:1168-1181) and dropped if the view re-pins another profile mid-lookup (:1203-1209). Pinned by ClineProvider.spec.ts:3714-3841 and :4244-4268 and by ClineProvider.sticky-mode.spec.ts.
discussion_r4413258722 (feat(webview): setValues batch persistence and reset cleanup (N4, split 4/5 of #1546) #2236, mode clears landing while the profile load is pending) - latent here, and the clearer that would make it live belongs to F1c. The merge already tracks change rather than testing against undefined (comment ClineProvider.ts:1188-1194, the three !Object.is arms at :1211, :1219, :1227) and _updateViewLocalStateFromMutation deletes the key on an undefined write (:5600-5625), so a clear of a value the buffer held is detected and stays cleared; only a durable clear with no prior buffer value leaves the pre-load read at :1148 authoritative. No production path writes mode: undefined through ClineProvider.setValue or setValues on this head: handleModeSwitch passes a slug (:2808), the rollback goes straight to contextProxy and bypasses the buffer hook (:2834), and deleteCustomMode passes defaultModeSlug (webviewMessageHandler.ts:2912, :2924). The launch handshake is F1c (PR fix(webview): send stable view-state id on launch and re-pin per-view state #1552: webviewDidLaunch to setViewStateId, launch re-pin through the merged getState(), updateSettings via provider.setValue), which this unit explicitly defers to the follow-up; recorded for that unit's owner so the presence-based check lands with the clearer.
Controls and gates. Both new tests are red at a639813 (the crafted map replaced the seeded sibling entry; the loop called contextProxy.setValue for viewStates) and green at 75add35. Committed-tree lanes: ClineProvider.spec.ts 475 passed, webviewMessageHandler.spec.ts 175, sticky-mode 29, sticky-profile 25, ContextProxy 64, importExport 55, api-start-new-task 6, api-start-task-logging 8. The compile job's own command list was run in job order: lint, check-types, test:code-qa-ci, solheim-smoke:check-types, test:agent-evals:unit, agent-evals:check-types, lifecycle:model-check, webview-recovery:check-types, webview-recovery:model-check and mcp:integration-check all exit 0. format:check is red locally on 2005 files and none of them is a file this PR touches: they carry CRLF in the working tree while every blob is LF (14 of 15 sampled flagged files have CR, blob CR 0), and the same blobs re-checked after LF normalisation pass prettier --check, so the local red is an artefact of the checkout, not of the head. test:solheim-smoke-ci (18) and test:solheim-smoke:unit (1) are box-local too: record.sh needs ffprobe/ffmpeg, absent here (the 127 vs 143 assertions are command-not-found against a SIGTERM code), and config.test.ts:54 asserts the POSIX path /tmp/isolated/.config against this box's backslash form. ESLint suppressions unchanged at 3298. Threads on #1550: 0 unresolved of 71; the verdict is still CHANGES_REQUESTED, which only a review can clear.
Review round 4 - the third door on this boundary (138b147)
Restating the viewStates row as an API-surface row prompted a measurement of the API surface, and the boundary had three doors rather than two. Door inventory at this head, stated so two guards are not read as a closed boundary:
Webview message handler - closed at 75add35. The per-key updateSettings loop wrote provider.contextProxy.setValue directly (src/core/webview/webviewMessageHandler.ts:894) and therefore walked past ClineProvider.setValues entirely, which is why the guard had to go inside the loop.
ClineProvider.setValues - closed at 75add35. This is also the door the public API startNewTask path reaches: its configuration goes to provider.createTask at src/extension/api.ts:256 and from there into setValues.
API setConfiguration - closed by this commit. RooCodeApi.setConfiguration (src/extension/api.ts:641, declared on the contract at packages/types/src/api.ts:134) took a whole RooCodeSettings object, sanitised it through withoutInvalidDisplaySettings - which validates only timeFormat, dateFormat, showRelativeTimes and language and states at src/core/config/displaySettings.ts:14 that any other key is never invalid there - and wrote it at :643 before this commit, :657 at this head, through contextProxy.setValues, walking past ClineProvider.setValues, then handed the same object to providerSettingsManager.saveConfig at :644 before this commit, :658 at this head. So the harm was not only a stale in-memory map: a crafted value persisted into the profile config file as well, and an explicit unset erased the registered map, since globalState.update(key, undefined) deletes (the repo relies on that at ContextProxy.ts:173, :280-282, :305, :346). The key is now dropped before both writes and logged, with the same host-ownership rationale as the other two doors.
The read side stays open deliberately and is recorded as open: getConfiguration (src/extension/api.ts:626-629) returns getValues() minus secrets, so an API caller can still read the registered map. Reading it is not the hazard the finding describes, and guarding it would change what existing callers see for no defect shown. So on this head the boundary is closed at all three write doors and open at one read door.
Test and control: src/extension/tests/api-configuration.spec.ts pins that setConfiguration({ viewStates: {...}, soundEnabled: true }) calls contextProxy.setValues and saveConfig with { soundEnabled: true } only and logs the ignore; it is red at 75add35 without the drop (setValues received the crafted map) and green with it. Lanes on the committed text: api-configuration 10, api-delegation-events 6, api-delete-queued-message 3, api-has-task-ui-message-text 8, api-send-message 6, api-start-new-task 6, api-start-task-logging 8, api-task-conversation-history-length 23, api-terminal-profile 1, api-theme-fixture 2, displaySettings 22, ClineProvider 475, webviewMessageHandler 175, all passing; src tsc --noEmit exit 0; neither touched file carries an eslint suppression and the total held at 3298. The compile-job command list was run again in job order with the same results as round 3: green at lint, check-types, code-qa-ci, solheim-smoke check-types, agent-evals unit and check-types, lifecycle model-check, webview-recovery check-types and model-check and the MCP OAuth check; format:check red locally on 2004 files, none of them touched here (working-tree CRLF against blobs whose CR count is 0, and the touched files pass prettier --check after LF normalisation), and the two solheim record.sh suites still need ffprobe and POSIX path separators, which this box lacks.
Review round 5 - assertion strength on the same guard (696aa22)
The last live row on this PR was a test-strength finding on the round-3 handler case, and it was right: expect.anything() excludes undefined and null, so a not.toHaveBeenCalledWith on the key plus expect.anything() passes even if the updateSettings loop wrote the key with an undefined value - the shape that erases the registered map, since ContextProxy reads an undefined value as a delete. The shipped guard (src/core/webview/webviewMessageHandler.ts:790) drops on the key regardless of value, so behaviour was never wrong; the gap was that the assertion could not see the erase, and the same file already pins the undefined shape for another key at :2109-2116, which makes the weaker form easy to copy.
696aa22 adds webviewMessageHandler.spec.ts:2148-2162: an unset viewStates alongside a real setting must produce no write for the key - neither the undefined value nor the Anything matcher - must still write the other key, and must log the ignore. Control: guard block removed gives 2 failed | 174 passed with this case failing on [ 'viewStates', undefined ]; guard in place gives 176 passed, exit 0. Test-only change, no behaviour touched. The asymmetry between the two doubles is recorded in the commit message because it generalises: the provider-side test is erase-safe for free because it asserts on stored state (ClineProvider.spec.ts:9038-9040), while the handler double is a bare setValue mock and must pin the call and its value.
Gates on this head: handler spec 176 passing on the committed text, src tsc --noEmit exit 0, eslint clean with the file's single entry unchanged at 35 and the suppressions file byte-identical to its blob at 3298, and the compile-job command list reproduced the round-4 result exactly (green everywhere except the two box-local reds: format:check on 2004 locally-CRLF files, none of them the file touched here, and the two solheim record.sh suites that need ffprobe and POSIX separators). The three write doors named above are untouched by this commit; it strengthens the evidence behind door 1.
Review round 6 - the explicit unset at the API door (d19bb3f)
The live row on this head asked for the unset shape at the API boundary, and it was right: withoutInvalidDisplaySettings filters through Object.entries, so a key holding undefined survives it and reaches both writes, and ContextProxy reads an undefined value as a delete. api-configuration.spec.ts:109-137 now pins that setConfiguration({ viewStates: undefined, soundEnabled: true }) leaves both contextProxy.setValues and providerSettingsManager.saveConfig with an object that strictly equals { soundEnabled: true }, against the profile name default, and logs the ignore. Control: the guard block at src/extension/api.ts:645-656 removed gives 2 failed | 9 passed with this case red on expected { viewStates: undefined, ... } to strictly equal { soundEnabled: true }; guard in place gives 11 passed, exit 0.
Worth recording because it decides whether a case in this family has teeth: toHaveBeenCalledWith compares the way toEqual does and ignores undefined-valued keys - measured here with a throwaway probe - so assertions written only in that form pass on an unwritten drop of an unset. The strict assertions on the captured arguments are what bite; the loose ones stay beside them. Test-only change, gates unchanged from the previous heads (compile-job list 1,0,0,0,1,1,0,0,0,0,0,0,0 with the same two box-local reds), api-configuration 11 / displaySettings 22 / ClineProvider 475 / webviewMessageHandler 176 on the committed text.
Webview state now persists per panel, including its mode and selected API configuration.
Tab-specific title-bar actions target the appropriate panel, with clearer behavior when opening or focusing tabs.
Bug Fixes
Improved reliability when switching or deleting API profiles and custom modes, including recovery from failures.
Settings imports and API updates now preserve host-managed view state rather than overwriting it.
The PR adds persisted per-view state and excludes that state from settings transfer and webview writes. It updates profile operations and error handling. It also adds tab-specific commands and changes panel tracking, reuse, and creation behavior.

Security Architecture Review
Security architecture risk:🟡 Moderate · up to cd903
Per-view selections affect which service receives task data, but a view’s profile label can diverge from its effective connection settings. Resetting settings can also leave other open views holding usable cached credentials. The demonstrated scope is the extension’s local views and configured services, not a new remote or cross-tenant authority boundary.
Retained concerns
Medium · security · inferred: A view’s pinned profile identity is not bound to its effective API configuration. Activation and upsert persist the local profile name but clear the API configuration overlay. After another view activates a different profile, the first view still reports its own profile name while new tasks consume the other profile’s shared connection settings. Unlike the base, identity and configuration no longer follow the same shared selection. This can route task data to an unintended configured service. Durable-write failures can additionally leave the old pin alongside newly committed shared settings.
Medium · security · inferred: Resetting shared settings invalidates only the initiating view’s local cache. Another live view that hydrated a profile can retain its API configuration, including credentials, after shared state and stored profiles are reset. Because the merged read gives that overlay precedence and task creation consumes it, new tasks in that sibling view can continue using pre-reset credentials. The base lacked this additional cached configuration path; existing running-task credential retention is not attributed to this PR.
Security review details
Security Blast Radius
inferred — The supported concerns affect live views sharing an extension settings/profile context and tasks using their configured API services. They can change effective data destinations or retain credentials locally. No new webview-controlled cross-view identity adoption or cross-tenant authority was demonstrated at this head.
Security Findings and Attack Paths
inferred — Ordinary profile selection in a sibling view can change the shared API configuration while another view retains a different profile label. Starting a task in that first view consumes the changed configuration. This supports unintended-service exposure, not a demonstrated unauthenticated attacker or verified policy bypass.
inferred — A sibling with hydrated credentials can retain them through another view’s global reset and supply them to a subsequently created task. Clearing the shared store is counterevidence against durable secret retention, but does not invalidate that live sibling’s overlay.
Trust Boundaries and Controls
observed — Task creation retains organization allow-list validation before constructing a Task owned by the receiving provider. Panel lookup uses the actual VS Code view object. These controls limit the supported concerns but do not establish consistency between a profile label, cached credentials, and effective connection settings.
Resilience and Maintainability Implications
observed — Hydration rejects superseded identities and preserves fields changed during asynchronous loading. Failed persistence does not poison the shared write queue, and mode switching attempts shared-state rollback on durable failure. These controls do not reconcile partially committed profile transitions or invalidate sibling caches during reset.
Hardening Proposals
proposed — Define one coherent per-view profile/configuration commit and explicit reconciliation after partial failure. Global credential reset should invalidate every live view’s configuration cache before new tasks can consume it.
proposed — Before wiring stable webview identity adoption, bind identity to the owning view and require collision-free identifiers rather than treating syntax normalization as ownership validation. This is a follow-up design safeguard, not an observed reachable vulnerability in the reviewed head.

The title names the main change: getState() now merges view-local state into its result so per-view overrides take effect. The changeset matches this. It adds a viewStates schema, a merge in ClineProvider.getState(), spec coverage for the merge, and related per-view persistence fixes. The title uses the conventional-commit form and stays under the usual length. It does not mention the broader persistence and command changes in the same diff, which the title does not need to cover.
Full details: Security Boundaries
Explanation
The prior security finding remains unresolved. A crafted webview message {type:"mode", text:"invalid-mode"} reaches webviewMessageHandler.ts:2204-2205, where the cast provides no runtime validation. This PR changes ClineProvider.handleModeSwitch (ClineProvider.ts:2760-2763, 2806-2808) to call setValue("mode", newMode). setValue performs no mode validation (5485-5498), then writes the value to shared state and the per-view buffer, and _persistViewLocalStateFromMutation stores it in durable viewStates (5650-5665). The setValues validator (5569-5578) does not protect this direct path. The changed path therefore trusts unvalidated webview input and persists an invalid mode. The current regression test explicitly expects this behavior at ClineProvider.sticky-mode.spec.ts:1009-1035.
Resolution
Validate the webview message before calling handleModeSwitch: require a string and resolve it with getModeBySlug(message.text, await provider.customModesManager.getCustomModes()). Add equivalent validation in handleModeSwitch or the direct mode setter so non-webview callers cannot bypass the control. Reject invalid input before task-history, shared-state, view-local, or durable viewStates writes. Add a regression test that sends an invalid webview mode and verifies all affected stores remain unchanged.
Full details: Persistence Integrity
Explanation
The prior persistence-loss finding remains unresolved. ClineProvider.savePersistedViewState now returns early when viewStateId === viewId and stores mutations only in pendingViewState (ClineProvider.ts:797-809). The production webview still sends webviewDidLaunch without viewStateId (webview-ui/src/App.tsx:210 and webview-ui/src/context/ExtensionStateContext.tsx:635), and the launch handler does not call setViewStateId (webviewMessageHandler.ts:598-603). No production caller of setViewStateId exists. Therefore mode/profile mutations can remain pending indefinitely. When a tab view is disposed, the provider clears pendingViewState without persisting it (ClineProvider.ts:1663-1671; tab disposal at :1863-1866), so a changed mode or profile is lost during provider recreation.
Resolution
Generate or recover a stable webview ID in the webview. Include it in webviewDidLaunch. In the launch handler, await provider.setViewStateId(message.viewStateId) before posting initial state. Add a recreation test that changes a mode or profile before registration, recreates the provider, and verifies that the replacement loads the persisted value.
Full details: Description check
Explanation
The description does not follow the repository template. It has no 'Closes:' line with a linked issue. It has a placeholder 'Issue (created at PR-open time): #1549' and a separate reference to #1550 in the objectives, so the linked issue is unclear. The 'Description' and 'Test Procedure' content is present but sits under non-template headings such as 'What this unit lands at this head' and 'How to test'. The 'Pre-Submission Checklist', 'Visual Snapshots', 'Videos', 'Documentation Updates', and 'Get in Touch' sections are absent, and the checklist items are not marked. The body is long, mixes in many review-round logs, and is not written in short, plain sentences as the template asks. The content is substantive and specific, so the description is not off-topic. But the required issue link and template structure are missing or incomplete.
Resolution
Add a 'Closes: #<issue number>' line that names one approved issue, and remove the placeholder reference. Restructure the body under the template headings: 'Related GitHub Issue', 'Description', 'Test Procedure', 'Pre-Submission Checklist', 'Visual Snapshots', 'Videos', 'Documentation Updates', 'Additional Notes', and 'Get in Touch'. Mark each checklist item that applies. Add a Discord username under 'Get in Touch'. Move the review-round logs, negative-control notes, and per-head verification counts out of the description, or condense them to a short summary under 'Additional Notes'. Rewrite the text in short, active sentences that follow the Simplified Technical English style the template requests.
Full details: Regression Evidence
Explanation
ProviderSettingsManager.getCurrentProfileName() is a new public behavior without focused manager-layer coverage. The method reads load() and returns currentApiConfigName at src/core/config/ProviderSettingsManager.ts:508-513; it therefore has distinct stored-value, empty-secrets default, and read-error behavior at :514-516 and :699-705. The changed ProviderSettingsManager.spec.ts adds tests only for typed getProfile and deleteConfig errors. Repository references to getCurrentProfileName outside its implementation are production callers or mocks in ClineProvider tests, not direct manager tests.
Resolution
Add focused tests to src/core/config/__tests__/ProviderSettingsManager.spec.ts that call getCurrentProfileName() and assert: a stored profile name is returned; empty secrets return "default"; and a rejected secrets.get rejects with the exact Failed to read the active profile: ... error.
Full details: Lifecycle Resource Cleanup
Explanation
The changed tombstone lifecycle still leaks state after a successful activation. savePersistedViewState() and repointPersistedViewStates() append evicted IDs to prunedViewIdsDuringActivation at ClineProvider.ts:851-855 and :952-957. The only reset is _snapshotProfileActivationState() at :2966-2971, before a later activation. Successful activation and compensation completion do not clear the list. If one view clears an ID, another view's completed pruning still lists that ID, and the first view is disposed, _releaseClearedViewStateIds() moves the tombstone to clearedViewStateIdsWithoutOwner at :1020-1028. No later activation means _drainUnguardedClearedViewStateIds() never runs. The static tombstone and the other provider's retained eviction list then remain for the host lifetime. The added tests only drain the state by starting another activation at ClineProvider.spec.ts:4975-5022; they do not cover successful activation followed by disposal without another activation.
Resolution
Tie each pruning record to its activation group. Clear or finalize prunedViewIdsDuringActivation in a finally path after successful activation and after compensation completes. During disposal, remove owned tombstones after queued activation work settles, or transfer them only to a live rollback group with an explicit completion path. Add a regression test that performs a real pruning/clear race, completes activation successfully, disposes the tombstone owner, and asserts that neither static tombstone set nor the completed provider's eviction list retains the ID without a later activation.

No cleanup change is needed. The outer beforeEach creates a fresh mockContext and globalState before each test, so these stubs do not leak into later tests.
No change required.afterEach clears both sidebarPanel and tabPanel in the registerCommands tests, and openClineInNewTab has equivalent beforeEach cleanup.
Mutation gate on the added lines — 0c6f79b63, 8ef71e68e
scripts/stryker-diff.mjs ci over the delta of these commits (--base 702a15d93 --head 8ef71e68e, 93 changed executable lines in src/core/webview/ClineProvider.ts, test paths excluded as the gate does) produced 91 mutants: 88 killed, 3 surviving, 0 uncovered.
The first preflight run left 23 survivors. Sixteen of them were real test gaps and are covered by 0c6f79b63 (a write that clears an entry, a write that re-lands it and lifts the tombstone, a failed write that must put the tombstone back, a drain that must respect a live eviction list, and the compensation guards for a newer sibling write, a task pinned to another profile, a task replaced mid-compensation, and the restore-failure log). One more, replacing [...applied].reverse() with [...applied], was killed by 8ef71e68e: both sibling restores now fail, so the case asserts the later sibling is put back before the earlier one (measured by dropping .reverse(): expected 0 to be greater than 1 at src/core/webview/__tests__/ClineProvider.spec.ts:7060).
The three remaining survivors are equivalent and are disclosed rather than suppressed — no Stryker directive was added:

why no test can distinguish it
ClineProvider.ts:859
else if (tombstoneTransition === "lifted") → true
tombstoneTransition is assigned exactly "added" or "lifted" by the ternary at :833, and the branch above already handles "added"; control only reaches the else if when the value is "lifted", so the condition is necessarily true there.
ClineProvider.ts:4125
task?.taskApiConfigName === name → true
previousTaskApiConfiguration is only ever assigned from task?.taskApiConfigName === name ? task.apiConfiguration : undefined, so a truthy value of the first operand already proves this one.
ClineProvider.ts:4125
task?.taskApiConfigName → task.taskApiConfigName
Same derivation: a truthy previousTaskApiConfiguration implies task is defined, so the optional chain cannot short-circuit on this operand.
For context: the CI mutation-diff row on this PR (e.g. job 126870243312 at 28cae0635) reports the whole PR delta (+9363/−569 over 24 files), which is above the gate's 500-changed-line / 400-mutant caps on its own, so that advisory row stays red for size reasons independent of these commits. The numbers above are the unit-shaped measurement for the lines this round added, which is the shape the fold into #1919/#1921 inherits.

Handle an uninitialized task mode during rollback snapshotting.
Task.taskMode throws before initialization. The new snapshot read runs before any mode-switch write, so a mode switch on a newly created task can fail before the requested change. Treat an uninitialized mode as undefined; the existing rollback logic already skips restoration for that value.

Clear pendingViewState when clearing view-local state.
A pre-registration change is stored in pendingViewState. resetState() clears viewLocalState and persisted state, but leaves this buffer intact. Later, setViewStateId can persist the stale value under the stable ID and reload it into viewLocalState.
Add a regression test that holds a pre-registration change, calls resetState(), registers the stable ID, and asserts that the cleared state is not persisted or restored.

Failed pre-merge checks:
- Regression Evidence:
Add focused `ProviderSettingsManager.spec.ts` tests for missing `getProfile({
name })` and `getProfile({ id })`. Assert each rejection is an instance of
`ProviderSettingsNotFoundError` and retains the expected message.
- Persistence Integrity:
Wire the stable webview identity into the actual launch message and handler.
Await `setViewStateId` and its load before the first `postStateToWebview`, or
otherwise guarantee registration before provider disposal. Post state again only
after asynchronous state loading completes. Add an end-to-end launch/recreation
test that changes a mode or profile before reload and verifies the replacement
loads it.
- Lifecycle Resource Cleanup:
Tie each tombstone to the specific activation/rollback that can consume it.
Clear the activation's eviction guard when that activation and its compensation
queue settle, then remove tombstones whose guard is gone. On provider disposal,
remove owned tombstones after in-flight activation work settles, or transfer
only to an explicitly tracked live rollback. Keep the failed-write rollback that
removes provisional tombstones.

# AGENTS.md
## ESLint Suppressions
When writing new code:
- Avoid `as any`; use typed APIs directly (e.g. `RooCodeEventName.X` constants with typed `on()`/`listenerCount()`), or bracket notation (`obj["privateField"]`) to access private members. Prefer precise test doubles or `unknown` with a type guard over double assertions (`as unknown as T`); use double assertions only as a last resort, with a comment explaining why.
The regression-evidence row on this change pointed at the one part of it that had no
test: getProfile throws ProviderSettingsNotFoundError for a missing name and for a
missing id, and its own catch re-throws that type unwrapped so callers can treat an
already-deleted profile as an idempotent no-op instead of matching message text. Only
deleteConfig had such an assertion.
Two cases added here, one per lookup branch. Measured controls: deleting the typed
re-throw guard turns both cases red with "expected Error: Failed to get profile:
Config with... to be an instance of ProviderSettingsNotFoundError"; replacing the name
branch's typed error with a plain Error reddens only the name case, and replacing the
id branch's reddens only the id case. Restoring the source byte-identically returns
62/62 green.
…der goes away
A change made before the webview registered a stable id waits in memory, and until now
the only thing that ever wrote it was that registration: a provider disposed before
registration lost the change instead of putting it on disk. The pre-registration hold
stays - a temporary-id write was the original defect, because temporary ids restart from
0 on every host start - but dispose now flushes whatever it still holds through the same
serialized write queue, and a durable write that fails there is logged instead of turning
teardown into a rejection.
The flush lands the entry under the only id this instance ever had, which loadViewState
refuses to attribute to any view, so it is a durability record rather than something a
later view can load as its own.
Measured controls: dropping the dispose flush, and neutering savePersistedViewState's
forceUnregisteredWrite operand, each fail the new case with "expected [] to deeply equal
[ 'sidebar-1' ]" at src/core/webview/__tests__/ClineProvider.spec.ts:4859. The failure case
rejects with a non-Error so both branches of the teardown log are pinned, and a provider
disposed with nothing held is asserted to write nothing and to claim no flush. Six suites -
the five webview ones plus the profile manager - are green, tsc and eslint are clean, and
src/eslint-suppressions.json is unchanged.
Panel rows after e0cb48c51 — the loss window is closed, the wiring half is a scheduled scope
1. The durability guarantee (added in e0cb48c51, "flush a held pre-registration view state when the provider goes away").
The row is right that a held change must not evaporate. The hold itself is kept — writing under a temporary id was the defect (nextViewId restarts from 0 on every host start, src/core/webview/ClineProvider.ts:324/:586, so an entry under one is not attributable to the view that wrote it) — but the provider now writes what it still holds before it disappears:
dispose() flushes pendingViewState through the same serialized write queue before leaving activeInstances (src/core/webview/ClineProvider.ts:1674-1687), via a new forceUnregisteredWrite option on savePersistedViewState (:796-807) that bypasses only the hold.
The entry lands under the only id this instance ever had. loadViewState refuses to attribute a temporary-id entry to any view (:1134-1140), so this is a durability record, not something a later view can mis-load — which is the difference from the pre-deferral shape, where a fresh session's view could read the previous session's sidebar-0 entry as its own.
A durable write that fails there is logged and teardown still completes: [dispose] Unable to flush the unregistered view state of view … (:1680-1686).
Three cases pin it: writes a held pre-registration change to storage when the provider is disposed, keeps tearing down when the pre-registration change cannot be flushed (rejects with a non-Error so both branches of the teardown log are exercised), and does not write anything when a provider is disposed with nothing held. Measured controls: dropping the dispose flush, and neutering the forceUnregisteredWrite operand, each fail the first case with expected [] to deeply equal [ 'sidebar-1' ] at src/core/webview/__tests__/ClineProvider.spec.ts:4859.
2. The launch-wiring half belongs to the unit that owns webviewDidLaunch.
On this unit setViewStateId has no production caller — that is disclosed in this thread above — and the registration call ships with the unit that owns the message handler:
fix(webview): isolate parallel mode and provider profile writes (vps2 F3) #1560 (557f1c9b4, vps2/f3-mode-profile-writes): src/core/webview/webviewMessageHandler.ts:595-602 — case "webviewDidLaunch" calls await provider.setViewStateId(message.viewStateId), with the registration failure caught at :603-606 so a later launch retries registration and loadViewState.
So #1550 lands the storage/registration primitive (validation, the claim rule, the buffer, the flush, the tombstones) and the launch message + awaited registration + post-after-load arrive with the unit that owns the handler and the webview side of that message. Treating that half as scheduled scope rather than a finding on this unit's contract.
3. Regression Evidence row: addressed by 35a1aecb1.ProviderSettingsManager.spec.ts now has a negative getProfile({ name }) and getProfile({ id }) case, each asserting rejects.toBeInstanceOf(ProviderSettingsNotFoundError) and the unwrapped message. Controls: deleting the typed re-throw guard reddens both with expected Error: Failed to get profile: Config with… to be an instance of ProviderSettingsNotFoundError; un-typing the name branch reddens only the name case, un-typing the id branch only the id case.
4. Mutation gate at e0cb48c51 (unit-shaped delta vs 702a15d93, 108 changed executable lines, test paths excluded): 101 mutants — 98 killed, 3 surviving, 0 uncovered. All three are disclosed, no directive: ClineProvider.ts:866 (else if (tombstoneTransition === "lifted") → true: the ternary at :840 yields only "added"/"lifted" and the branch above handles "added"), ClineProvider.ts:4153 (task?.taskApiConfigName === name → true, and the optional chain removed: previousTaskApiConfiguration is assigned only from that same predicate, so a truthy first operand already proves it). Earlier survivors from 28cae0635 were closed by 0c6f79b63/8ef71e68e; the CI mutation-diff row stays red for size reasons (whole-PR +9363/−569 over the 500-line / 400-mutant caps) and is not affected by these commits.
Local state at e0cb48c51: six suites (five webview + profile manager) 747/747 green, tsc --noEmit clean, eslint --max-warnings=0 clean on the touched files, src/eslint-suppressions.json byte-identical. Commits added this round: 6a21695f5, db93970af, 28cae0635, 0c6f79b63, 8ef71e68e, 35a1aecb1, e0cb48c51.

All seven required lanes are green at e0cb48c51 (check-translations, platform-unit-test ubuntu + windows, compile, knip, e2e-mock, Build test VSIX). Two advisory rows are red:
mutation-diff — red for size reasons only (whole-PR +9363/−569 against the 500 changed-line / 400-mutant caps), unchanged by these commits; the unit-shaped local run is 98 killed / 3 disclosed equivalents.
webview-visual — was success at the previous head 8ef71e68e and is failure at e0cb48c51 (job 126896213407, step "Run webview visual tests", 0 annotations). The failing case is a colour-contrast assertion on a welcome-screen fixture: WelcomeViewProvider.visual.tsx:8:2 › renders the full welcome screen in the VS Code high-contrast-light theme → high-contrast-light welcome action boundary: 2.34:1 (required 3:1; foreground rgba(34, 88, 142, 0.494); background rgba(255, 255, 255, 1.00)), Expected: >= 3, Received: 2.337314441758872.
Between those two heads the only commits are 35a1aecb1 (spec-only, under src/core/config) and e0cb48c51 (src/core/webview/ClineProvider.ts + its spec) — no webview-ui source and no baseline/snapshot files are touched. The same lane passes at their current heads on #1523 (b2b31f74c, job 126863857747) and #1924 (fc17bc41b, job 126843851086).
Requesting a re-run of that job for e0cb48c51: no timeout bump, no skip, no baseline change, and no code change from me for this row.
Reply to the Persistence Integrity row at e0cb48c51
The loss window the row describes is closed by e0cb48c51: dispose() now writes a change that was still waiting for a stable id before the provider goes away (src/core/webview/ClineProvider.ts:1674-1687, via forceUnregisteredWrite on savePersistedViewState at :796-807), and the pre-registration hold itself stays because writing under a temporary id was the original defect.
The detail that makes this a guarantee rather than a second defect: the flushed entry lands under the only id this instance ever had, and loadViewState refuses to attribute a temporary-id entry to any view (src/core/webview/ClineProvider.ts:1134-1140, nextViewId restarts from 0 on every host start at :324/:586) — so what dispose writes is a durability record for the held change, not state a later view can mis-read as its own. Pinned by writes a held pre-registration change to storage when the provider is disposed, with the failure case and the nothing-held case beside it; the measured controls are listed in the comment above.
The remaining half of the row (launch message → setViewStateId, awaited registration, post-after-load) is scheduled scope: #1560 and #1562 carry webviewMessageHandler.ts:595-602 that performs the registration, as quoted above.
…able to fail
Thread rt4473642023 (Major): the rename-compensation ordering check compared
findIndex results taken from two different mocks, so no ordering of the delete
and the restore could change its outcome. The indices now only select which call
to look at, and the comparison reads mock.invocationCallOrder, which vitest
numbers across every call - the shape the deleteCustomMode test above already
uses. Measured by hoisting the compensation restore above the delete of the old
name: the old assertion stayed 139/139 green, the new one reddened with
expected 549 to be greater than 550, and both are green again once the hoist is
reverted.
Thread rt4473641992 (Trivial): the retained-survivor test seeded the profile
list and the selection but never the shared provider settings, and asserted
names only, so a deletion that paired the survivor name with another profile's
settings passed. Seed the shared settings through contextProxy.setProviderSettings
the way an activation leaves them, and assert the payload now paired with the
survivor name. With a control that writes the first survivor's payload into the
shared store, the seeded test reddened (expected gpt-4.1 to be gpt-4o) while the
names-only version of the same test stayed 25/25 green.
Test-only: no implementation file is touched, and eslint-suppressions stays
byte-identical at 3302.
…e reset fails
deleteCustomMode routes the reset back to the default mode through provider.setValue so the per-view buffer mirrors the shared write. When the per-view half fails, provider.setValue restores the value it captured before the write - here the slug deleteCustomMode just removed - and rethrows, so the shared mode names a mode that no longer exists and both postStateToWebview and the sibling fan-out are skipped: the webview keeps showing the deleted mode and the shared store names a slug that is gone.
Catch the failure and log it, put the shared store back on the default slug through the shared layer only (the per-view record is what failed), then post and fan out exactly where they were. The order the spec pins - fan-out after setValue - is untouched.
The handler-layer test added here is the one that would have failed for the bug: control at the previous head with the new test in place gives 1 failed / 139 passed (the per-view rejection escapes), with the fix the file is 140/140. The rejection is mocked with Once so it cannot leak into the tests that follow and reuse the same double.
Merge base 3ee042d. The merge brings main's 113 changed paths; exactly one conflicted and was resolved by hand: src/core/webview/ClineProvider.ts, three hunks.
Imports: both sides kept - main's withoutInvalidDisplaySettings import beside this branch's ProviderSettingsNotFoundError import, which the unit's invalid-mode handling needs.
getStateToPostToWebview field list: main added timeFormat, dateFormat and showRelativeTimes read from stateValues; this branch renamed that binding to mergedStateValues because it merges the view-local buffer over the shared values. Our naming is kept and main's three fields are read from the merged source, in main's position, with main's defaults.
setValues: main replaced the body with one filtered write. This branch carries the invalid-mode guard, the view-local half of the write, and the rollback of both halves when a write fails. Main's filter is applied first and its result is what the rest of the body writes, so an invalid display value still never reaches ContextProxy, and everything this unit added is kept beside the filter rather than replaced by it.
Fidelity, measured rather than inferred from a green build:
- 104 paths main changed that this branch never touched: 0 differ from main in the merged tree.
- 15 paths only this branch changed: 0 differ from the pre-merge head.
- describe/it/test titles main added on test files main modified: 185 added, 185 present.
- substantive lines main added in the 5 shared non-test code files: 73 added, 68 present verbatim. The 5 are main's three display entries, re-expressed against this branch's binding name, and main's filter call, which survives bound into sanitizedValues in prettier's multiline shape.
- substantive lines this branch added in the 9 shared files: 3795 added, 3794 present. The 1 is the spread of values that main's filter replaced on purpose.
- the four lines main deleted from ContextProxy that still appear in the merged file appear in main's own blob at the same counts, so they are main's re-introduced lines and not leftovers of an older shape.
Suppression totals: merge base 3305, main 3301, pre-merge head 3302, merged 3298. No file or rule increased against either side.

Review comments at @src/core/webview/ClineProvider.ts:
- Around line 1675-1688: Remove the dispose-time forced persistence of
unregistered view state in the ClineProvider disposal flow; clear
pendingViewState without writing it under the temporary viewId, since no loader

failures to expect the held change to be discarded.
- Line 3424: In the activation flow, assign activationMode only after
snapshotSiblingOverlaysBeforeSharedSettingsWrite and the getModeConfigId read
complete, immediately before the write group containing setModeConfig; this
prevents compensation from clearing a mapping when no write started while
preserving fallback behavior for a failed mapping read. Add a test where
upserting with activate: true encounters a sibling pinned-profile read failure
and verify setModeConfig is never called.
Review comments at @src/core/webview/webviewMessageHandler.ts:
- Around line 2719-2721: Update the profile lookup in the webview message
handler to use provider.getProviderProfileEntries() instead of
provider.providerSettingsManager.listConfig(), so deletion resolves entries from

- Around line 2588-2592: In the rename flow around getProfile and
normalizedRenamed, verify the read-back record’s id matches the id being renamed
before accepting it; on mismatch, abort through the existing error path before
re-pointing views or deleting oldName, while preserving the existing safeguard
against removing a record owned by another rename.

Failed pre-merge checks:
- Persistence Integrity:
Add production launch identity wiring. Generate or recover a stable webview ID
in the webview, include it in the launch message, and handle it by awaiting
`provider.setViewStateId(message.viewStateId)`. Await registration and state
loading before the first `postStateToWebview`, or post a fresh state after
loading completes. Add a recreation test that changes a mode or profile,
recreates the provider, and verifies the replacement loads the persisted value.
- Lifecycle Resource Cleanup:
Tie each tombstone to the activation group that can consume it. Clear or
finalize `prunedViewIdsDuringActivation` when the activation and its
compensation queue settle, including successful completion. On provider
disposal, remove owned tombstones after in-flight activation work settles, or
transfer them only to an explicitly tracked live rollback. Preserve the existing
failed-write rollback that removes provisional tombstones, and add a regression
test where one provider completes an eviction, the clearing provider is
disposed, and no later activation occurs.

3739-3760: A failed deletion still leaves a re-pinned sibling's active task on the survivor's settings.
The rollback loop restores the sibling's pin and overlay. rePinViewLocalStateForDeletedProfile also rebuilt the sibling's task handler and changed its sticky profile name, and the rollback does not undo either one. getStateToPostToWebview prefers the task's own configuration and name over the view state. The task therefore keeps running on the survivor after the deletion reports failure.
3793-3806: The persisted-pin rollback can still overwrite newer sibling state.
The guard at Line 3797 only checks that the entry still names profileToActivate. A sibling that saves a newer mode while keeping the survivor profile still passes the guard. merged[viewId] = entry then replaces that newer mode with the snapshot's old mode.
An intentional clear is also reversed. The rollback restores any absent entry without checking clearedViewStateIds, so a sibling's deliberate clear comes back.
…Clicked
plusButtonClicked focuses the sidebar pane and waits for the view to resolve only when the
provider has no view yet, which is the command-palette path. The view/title menu path invokes
the same command after resolveWebviewView has already handed the provider its view, and no
test exercised that branch: the gate test sets isViewLaunched to false and the shared mock
double leaves it undefined, so both ran the not-launched path.
The added test pins the guard. Control measured at 375e255: unwrapping the condition so
focus and the wait run on every click leaves the suite without this test green at 59 of 59,
and reddens exactly the new test with it (1 failed of 60, "expected vi.fn() to not be called
with arguments: [ StringContaining ]"). Removing the block outright - never focusing - reddens
the existing gate test instead, so both branches are pinned now.

…ping rollback
Review threads 2 and 3 on Zoo-Code-Org#1550.
Thread 2. A provider disposed while a pre-registration change is still held used to flush it
under its own session-local id. loadViewState refuses to attribute a temporary-id entry to any
view (ClineProvider.ts:1144), so nothing can read that record back, while the write stamped
updatedAt and prunePersistedViewStates (1044) sorts newest-first and slices
MAX_PERSISTED_VIEW_STATES (326): the unloadable entry outranks loadable ones at eviction. The
condition for removing it was measured: nothing at launch drops temporary-id entries -
nextViewId is declared at 325 and consumed at 587 and nothing else recognises the shape, so
setViewStateId and loadViewState only decline to read such an entry, clearPersistedViewState
deletes its own id, and the tombstone drain touches bookkeeping only. Teardown now drops the
held change (1671) and the forceUnregisteredWrite option goes with the only caller that used
it. The method comment above savePersistedViewState already named this exact cost as the reason
pre-registration writes are held back; the dispose path was putting the same kind of entry into
the same map.
Tests: the one that asserted the flush lands is replaced by one asserting the held change is
dropped and nothing reaches storage; the one whose subject was a teardown flush that fails is
deleted, because that failure no longer exists. Control: against the previous ClineProvider the
replacement test fails with "expected { 'sidebar-293': { ...(2) } } to deeply equal {}" - the
unloadable entry landing - and the suite otherwise stays green at 472 of 474.
Thread 3. The profile-activation compensation restored the mode mapping whenever the mode had
been captured, and the sibling snapshot (3424) is awaited before the mapping write is issued, so
a failure there replayed a restore for a write that never started and cleared the current mode's
mapping on an upsert that never reached it. The rollback is now gated on and replayed from a
record created at the moment the mapping write is issued (3435, gate at 3508), so it names the
mode the write targeted and only runs if that write ran. The captured pairing itself was not the
defect: the previous activationMode had a single assignment, and both the write and the restore
read the same value.
Tests: the pre-issue case fails on the previous code, where setModeConfig was called once when
it should not have been called at all. Two more pin the captured pairing across a mid-window
change - the mode set to another mode after the capture, and the shared mode cleared after it -
which pass unchanged today; their control is a rollback that reads the live mode instead of the
record, and it reddens them together with the existing activation-rollback test. The rollback was
already tested (ClineProvider.spec.ts:6623 asserts the mapping returns to its prior id, and 6948
does the same again); what was untested was a failure before the write is issued and a mode

Record the mode-mapping write only after listConfig() succeeds.
Line 3435 sets modeMappingWrite before the activation array evaluates await providerSettingsManager.listConfig(). If that read rejects, setModeConfig(mode, id) never starts, but the catch still calls setModeConfig with the prior mapping. If the prior read also failed, this rollback can clear a mapping that this activation never changed. Resolve the list first, then set the marker immediately before issuing the mapping write. Add a test that rejects listConfig() and asserts that rollback does not call setModeConfig. (raw.githubusercontent.com)

- Regression Evidence:
Add `ProviderSettingsManager.spec.ts` tests that call the real
`getCurrentProfileName()` with a stored selection, with empty storage/default
initialization, and with a rejected secrets read. Assert the returned selection
and the exact wrapped read error.
- Security Boundaries:
Validate the mode before any task-history, shared-state, view-local, or durable
write. Require a string and resolve it with `getModeBySlug(message.text, await
provider.customModesManager.getCustomModes())`; reject invalid values. Also
enforce the same guard inside `handleModeSwitch` or the direct mode setter so
every caller is protected. Add a regression test that sends an invalid mode
message and verifies that global `mode`, `viewLocalState`, and `viewStates`
remain unchanged.

Add production launch identity wiring. Generate or recover a stable webview ID
in the webview, include it in the launch message, and handle it by awaiting
`provider.setViewStateId(message.viewStateId)`. Await registration and state
loading before the first `postStateToWebview`, or post a fresh state after
loading completes. Add a recreation test that changes a mode or profile,
recreates the provider, and verifies that the replacement loads the persisted
value.
- Lifecycle Resource Cleanup:
Tie each tombstone to the activation group that can consume it. Clear or
finalize `prunedViewIdsDuringActivation` when the activation and its
compensation queue settle, including successful completion. On provider
disposal, remove owned tombstones after in-flight activation work settles, or
transfer them only to an explicitly tracked live rollback. Preserve failed-write
rollback behavior, and add a regression test where one provider completes an
eviction, the clearing provider is disposed, and no later activation occurs.

mutation-diff is over the changed-line budget, not over a kill rate - requesting a maintainer decision
The only red check on this head (a63981380) is mutation-diff, and its gate step prints one line before exiting 1:
Mutation gate failed: extension has 1648 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.
The mechanism in one sentence: scripts/stryker-diff.mjs accumulates distinct changed executable line numbers per package, excluding __mocks__, __tests__, fixtures and test-utils by path segment (lines 84-85), and throws at the cap (lines 265-267) before Stryker is launched - so this lane is not reporting a kill rate at all, which is why the artifact step finds nothing under reports/mutation/. (The other warnings in that log - a Stryker launch ENOENT, a survived BooleanLiteral at packages/core/src/value.ts:1, and an EISDIR job-summary write - are output of the workflow's own node --test scripts/stryker-diff.test.mjs step, not of the gate.)
What those 1648 lines are: this lane measures the pull request delta against main, and this PR exists to carry a merged series, so it is that series being counted - src/core/webview/ClineProvider.ts alone is 2619 raw changed lines in the delta, src/activate/registerCommands.ts 240 and src/core/webview/webviewMessageHandler.ts 206. The rule fires the same way on every head of this round, 1656 at 375e25546, 1656 again at 09a0313c3 (which is a test-only commit, so the count is unchanged exactly as the path exclusions say it should be), and 1648 here - the drop of 8 is a63981380 removing more executable lines than it adds - and on the sibling branch at e8b2ac051, where the same rule reports 2264. For proportion: the two commits behind this head contribute 74 raw non-test lines in a single file, plus 220 test lines that the gate excludes by path segment.
Two remedies, and I would ask for the first:
A maintainer-reviewed narrow exclusion for the extension package on this PR, or a raised cap for a PR whose content is a merged series. Nothing is slipping past a mutation check, because the gate stops before mutation testing begins; the 20 other checks on this head are green, including platform-unit-test on both ubuntu and windows, e2e-mock, webview-visual, extension-host-visual, CodeQL and codecov/patch, so coverage of the changed lines is being reported by codecov rather than asserted here.
A further split, which on this PR would not be a trim but a re-plan of the stack: the discipline here records the unit plan on the tracking issue before any split PR is opened, so a split improvised under a red lane would itself be an unreviewed plan change.
The fork does not protect its main branch, so this check blocks nothing on the fork side either, and what currently blocks this PR is the review verdict rather than any context. Raising it here so the number and the mechanism are in front of a maintainer before the next round lands, rather than leaving it as a red that every reader has to reinterpret.

…rite boundary
The registered viewStates map is host-owned: ClineProvider rewrites it from a full read
(savePersistedViewState, clearPersistedViewState, prunePersistedViewStates), so a map handed
in through a settings write - the webview newTask taskConfiguration, or the extension API's
createTask configuration - replaced every other view's durable selection in one write, and an
explicit unset erased the map outright. Entries arriving that way are validated nowhere on
the path, so the key is dropped rather than sanitised; the rest of the settings object is the
caller's to set. mode, currentApiConfigName and apiConfiguration are untouched: those are the
acting view's own selections and already route through the per-view buffer.
The generic updateSettings loop writes through ContextProxy directly, bypassing setValues, so
it drops the same key before any side effect is run for it. provider.setValue is not guarded:
the only handler caller of it passes defaultModeSlug, measured at the call site.
Tests: ClineProvider.spec.ts pins the setValues door against a seeded sibling entry, and
webviewMessageHandler.spec.ts pins the updateSettings door. Both are red at a639813 without
the guards - the crafted map replaced the seeded one, and the loop called
contextProxy.setValue("viewStates", ...) - and green with them.
Lanes at this head: ClineProvider 475, webviewMessageHandler 175, sticky-mode 29,
sticky-profile 25, ContextProxy 64, importExport 55, api-start-new-task 6, api-start-task-
logging 8, all passing. Lint, check-types, code-qa-ci, solheim-smoke and agent-evals types,
lifecycle and webview-recovery model-checks, and the MCP OAuth check are green; the two
solheim record.sh suites need ffprobe (absent here) and config.test.ts asserts POSIX path
separators, so those two are box-local only.
…ration
RooCodeApi.setConfiguration takes a whole RooCodeSettings object and writes it at src/extension/api.ts:643
through contextProxy.setValues, which walks past ClineProvider.setValues, and then hands the same object to
providerSettingsManager.saveConfig at :644. The registered viewStates map is host-owned - ClineProvider
rewrites it from a full read of storage (savePersistedViewState, clearPersistedViewState,
prunePersistedViewStates) - so an API caller that handed one in replaced every other view's durable entry in
globalState and in the profile file, and an explicit unset erased it: globalState.update(key, undefined)
deletes, which the repo itself relies on at ContextProxy.ts:173, :280-282, :305 and :346, and the secrets
path deletes explicitly at :464-466. The pre-filter cannot catch the key either:
withoutInvalidDisplaySettings validates timeFormat, dateFormat, showRelativeTimes and language, and states at
displaySettings.ts:14 that any other key is never invalid there. The key is now dropped, with the same
host-ownership rationale the two webview doors use; the rest of the settings object is the caller's to set.
Door inventory for this boundary, so that two guards are not read as a closed boundary:
1. webview message handler - the per-key updateSettings loop wrote contextProxy.setValue directly
(webviewMessageHandler.ts:894) and bypassed setValues; closed at 75add35.
2. ClineProvider.setValues - closed at 75add35; this is also the door the API startNewTask path reaches,
whose configuration goes to provider.createTask at src/extension/api.ts:256.
3. API setConfiguration - the door this commit closes. The read side stays open on purpose:
getConfiguration (:626-629) returns getValues() minus secrets, and reading the registered map is not the
hazard the finding names; a read guard would change what existing callers see for no shown defect.
Test: api-configuration.spec.ts pins that setConfiguration({ viewStates: {...}, soundEnabled: true }) calls
contextProxy.setValues and saveConfig with { soundEnabled: true } only, and logs the ignore. Control: red at
75add35 without the drop - setValues received the crafted map - and green with it.

…nnot see
The review row on src/core/webview/__tests__/webviewMessageHandler.spec.ts:2134 was right about the
assertion, and the reason is worth keeping where the next person will read it. expect.anything() excludes
undefined and null, so not.toHaveBeenCalledWith("viewStates", expect.anything()) still passes when the
updateSettings loop writes the key with an undefined value - which is the shape that erases the registered
map, since ContextProxy reads an undefined value as a delete (ContextProxy.ts:464-466 for secrets, and
globalState.update(key, undefined) deletes, which this repo relies on at :173, :280-282, :305 and :346).
The shipped guard is not wrong: webviewMessageHandler.ts:790 drops the key regardless of value, so the
defect here was test strength rather than behaviour. It is worth strengthening anyway because the same file
already pins that undefined shape for another key at :2109-2116, so the weaker form is one copy-paste away.
The asymmetry between the two doubles is the general rule for this family, and it is why the new case asserts
the call rather than a value-shaped matcher: the provider-side test is erase-safe for free because it asserts
on the stored state (ClineProvider.spec.ts:9038-9040, where an unset write makes the equality fail), while
the handler double is a bare contextProxy.setValue mock that has to pin the call and its value. Copy the
stronger form, not the neighbour.
Case: updateSettings with { viewStates: undefined, alwaysDenyUnapprovedCommands: true } must never write
viewStates - neither as undefined nor through the Anything matcher - must still write the other key, and must
log the ignore. Control: with the guard block removed from webviewMessageHandler.ts the file reports 2 failed
| 174 passed, the new case failing with expected "vi.fn()" to not be called with arguments: [ 'viewStates',
undefined ]; with the guard in place it is 176 passed and exit 0.
Gates on the committed text: webviewMessageHandler.spec 176 passing, src tsc --noEmit exit 0, eslint clean
with the file's single suppression entry unchanged at 35 and src/eslint-suppressions.json byte-identical to
its blob at 3298. The compile-job command list was run in job order with the same results as the previous
heads: lint, check-types, code-qa-ci, solheim-smoke check-types, agent-evals unit and check-types, lifecycle
model-check, webview-recovery check-types and model-check and the MCP OAuth check green; format:check red
locally on 2004 files, none of them the file touched here, which passes prettier --check after LF
normalisation, and the two solheim record.sh suites need ffprobe and POSIX path separators that this box
lacks. Test-only change: no behaviour touched, no changeset, no CHANGELOG, no suppression increase.

Clear the acting view’s deleted-mode override after the fallback.
If provider.setValue("mode", defaultModeSlug) fails while persisting view state, it does not update the acting view’s local mode override. The fallback changes only shared mode. postStateToWebview() can therefore still report the deleted slug, and clearViewLocalModeForDeletedSlug() skips the acting view. Add a recovery path for the acting view’s local override, including the persisted entry when writes become available. ClineProvider.ts Lines 5112-5124, 5219-5224, and 5299-5321 establish this sequence. (raw.githubusercontent.com)

src/core/webview/ClineProvider.ts:3435 Minor · Data Integrity & Integration · Quick win
Record the mode-mapping write after the profile-list read succeeds.
If getModeConfigId(mode) fails and the subsequent listConfig() call rejects, modeMappingWrite is set before setModeConfig(mode, id) is called. The catch then restores undefined through setModeConfig, removing a saved mapping that this activation never changed. Resolve listConfig() before setting the write record, and add a test for this rejection sequence. ProviderSettingsManager.setModeConfig assigns the supplied value and serializes the record.

`Failed to read the active profile: ...` error.
- Security Boundaries:
Require a string mode in the webview message path and resolve it with
`getModeBySlug(message.text, await
provider.customModesManager.getCustomModes())`; reject invalid input before
task-history or state writes. Add equivalent validation in `handleModeSwitch` or
its direct setter so non-webview callers cannot bypass the control. Add a
regression test that sends an invalid mode message and verifies that shared
`mode`, `viewLocalState`, and durable `viewStates` remain unchanged.

Generate or recover a stable webview ID in the webview, include it in
`webviewDidLaunch`, and await `provider.setViewStateId(message.viewStateId)` in
the launch handler before posting initial state. Add a recreation test that
changes a mode or profile before registration, recreates the provider, and
verifies that the replacement loads the persisted value.
- Lifecycle Resource Cleanup:
Tie each tombstone to the activation group that can consume it. Clear or
finalize `prunedViewIdsDuringActivation` when activation and compensation
settle, including successful activation. During disposal, remove owned
tombstones after in-flight activation work settles, or transfer them only to an
explicitly tracked live rollback group. Add a regression test that completes an
eviction, disposes the provider that clears the entry, and verifies that neither
static tombstone set retains the ID without a later activation.

For persisted settings, verify the complete schema/storage/runtime/webview round trip, shared default semantics, and focused true plus false/unset tests.
Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases.
The row on src/extension/__tests__/api-configuration.spec.ts:101 was right that the API boundary pinned only
the populated map, and an explicit unset is the same hazard: ContextProxy reads an undefined value as a
delete - the repo relies on update(key, undefined) at ContextProxy.ts:173, :280-282, :305 and :346 - and
withoutInvalidDisplaySettings cannot catch the key either, because it filters through Object.entries, so a
key holding undefined survives it and reaches both writes.
One thing worth recording about the shape of the test, because it decides whether the case has teeth:
toHaveBeenCalledWith compares the way toEqual does and ignores undefined-valued keys. Measured with a
throwaway probe against this vitest: a mock called with { soundEnabled: true, viewStates: undefined }
satisfies toHaveBeenCalledWith({ soundEnabled: true }), while toStrictEqual on the same shape fails with
+ "viewStates": undefined. So an assertion written only in the loose form would have passed on this head
with the drop removed, and the strict assertions on the captured arguments are the ones carrying the teeth
here. The loose assertions stay next to them for continuity with the case above.
Case at api-configuration.spec.ts:109-137: setConfiguration({ viewStates: undefined, soundEnabled: true })
must call contextProxy.setValues and providerSettingsManager.saveConfig with an object that strictly equals
{ soundEnabled: true }, against the profile name default, and must log the ignore. Control: with the guard
block at src/extension/api.ts:645-656 spliced out the file reports 2 failed | 9 passed, the new case red on
expected { viewStates: undefined, ... } to strictly equal { soundEnabled: true }; with the guard in place it
is 11 passed, exit 0.
Gates on the committed text: api-configuration 11, displaySettings 22, ClineProvider 475, webviewMessageHandler
176, all passing; src tsc --noEmit exit 0; eslint clean, and neither touched file carries a suppression
entry, so src/eslint-suppressions.json came back byte-identical to its blob at 3298; the compile-job
command list reproduced the previous heads exactly in job order - 1,0,0,0,1,1,0,0,0,0,0,0,0 - with the same
two box-local attributions (format:check against 2004 locally-CRLF files, none of them the file touched
here, and the two solheim record.sh suites needing ffprobe and POSIX separators). Test-only: no behaviour
touched, no changeset, no CHANGELOG, no suppression change.

Keep the acting view's own mode when it does not name the deleted slug.
setValue("mode", defaultModeSlug) runs for every deletion. It writes the acting view's override as well as the shared value. If that view pinned architect and deletes a different custom mode, its architect override is replaced by the default. Sibling views keep their overrides for unrelated slugs, so the acting view is handled differently from its siblings.
Keep the shared mode reset unconditional, as it was before. Reset the acting view's override only when its current mode is the deleted slug. provider.getValues() merges the view-local override over the shared value, so it can make that check. Add a test where the acting view is pinned to a different mode and assert that its override is not written.

If listConfig() rejects at Line 3438, array evaluation stops before setModeConfig() runs. modeMappingWrite is already set, so the catch at Lines 3508–3513 restores a mapping this activation never changed.

Part of the vps2 durable per-view state series — tracked in fork issue 41 (cross-repo: the displayed vs-main diff includes the F1a content this unit branches from until F1a merges).
Issue (created at PR-open time): #1549
What this unit lands at this head
Fix unit F1b (2/3 of the F1 split). F1a landed per-view identity, the durable
viewStatespipeline, and the in-memoryviewLocalStatebuffer, butgetState()still read every field straight from the shared ContextProxy — so a webview reporting state ignored its own hydrated per-view selections. This PR:getState()merge —mergedStateValues = { ...contextProxy.getValues(), ...viewLocalState }; every per-view-capable field (mode,currentApiConfigName,apiConfiguration,modeApiConfigs) is served off the merge: a view-local selection beats the shared global value, unset fields fall back to the shared value with existing defaults untouched.apiConfigurationre-merges over the shared profile settings so the flat provider-settings mutation path stays coherent. The read path stays side-effect free.wroteUnderTemporaryViewStateId— first write claims the slot, load and re-key only touch entries this instance authored, authorship recorded only after the durable write lands), shared-write rollback insetValue/setValueswhen per-view persistence fails, and the null-prototype copy ingetPersistedViewStates.The webview launch-identity wiring that registers stable ids (F1c) lands in the follow-up.

The previous round's overlay-completeness change read the overlay from the merged state values, which also carry the raw
apiConfigurationstate key. That key is a partial patch written by shared-store paths, not a view snapshot: with no overlay present and the raw key partial,getState()served only the partial object and dropped the shared provider settings the previous merge produced (the parallel-mode activation tests caught exactly this - the activated profile's model id vanished; required lane red on the units carrying that spec). The overlay is now read from the view buffer itself, where a present value is by contract a complete profile and an absent one means the shared store serves the settings.Proofs: ClineProvider.parallelMode.spec green where present (the six synchronization tests that regressed), ClineProvider.spec green including the overlay-completeness tests, sticky-mode and webviewMessageHandler green; negative control: reverting the overlay to a shallow merge over the shared settings still reddens exactly the leak test; restores byte-exact (hash match); eslint

A review round on the view-identity unit found that the non-activating-save refresh updated pinned views' buffers but not their active tasks' API handlers, and the posted state prefers the task's own
apiConfiguration: a conversation running in a view pinned to the saved profile kept sending the old token (e.g. after the Zoo Gateway callback rotated it) even though the view's buffer had caught up. The refresh now rebuilds the affected tasks' handlers in the pinned views, and the non-activating branch rebuilds this view's own handler when it holds the pin.Proofs: ClineProvider.spec green (the pinned-sibling refresh test now asserts the active task's handler is rebuilt with the saved settings, not just the private buffer); negative control: dropping the rebuild from the refresh reddens exactly that assertion, restores byte-exact (hash match); parallelMode/sticky-mode/webviewMessageHandler green; eslint

The review round on the api-wiring unit named four test-quality issues; the ones present in this unit are fixed here: the
viewStatesdescribe block moved out of thealwaysDenyUnapprovedCommandsblock (test names carried the wrong subject), the prune test'stoBeDefined()survival checks replaced with exact-shapetoEqualassertions (they pass even if pruning strips fields), the stale-temporary-entry test's fixed 10 ms wait replaced with awaiting the load itself (the negative assertion could pass vacuously on a slow load), and the readiness-cancel test's fake timers restored in afinallyblock (a failed assertion left fake timers active and hung a later real-timer test).Proofs: global-settings 9/9 where present, ClineProvider.spec green, sticky-mode green where present, api-task-control green where present; negative controls: pruning that strips

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

The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.Updated this round (CodeRabbit follow-up, head 50aa367)

Upstream refresh (head df62613)

Upstream refactoredupsertProviderProfileinto a newpersistProviderProfilemethod and added arunToCompletionqueue option; this unit's transactional body was ported into the new method unchanged and upstream'sPromise.allSettledactivation fix was adopted in it. ClineProvider.spec, webviewMessageHandler.spec,tsc --noEmit, eslint (suppression counts unchanged) and prettier re-verified green at this head. The first refreshed head's windows unit-test lane caught that upstream's newupdateProfileModeltests inClineProvider.apiHandlerRebuild.spec.tsmock the settings manager with a staticgetProfile, which starves the post-save read-back; the mock now repointsgetProfileat whatsaveConfigwrote (the real manager's behavior), and the file's 38 tests pass locally alongside the rest of the verification set.Review round r111 - threads 1 and 3 (

They were re-measured against375e25546: the rename one already carries the ownership check and its test; the delete one names a method (syncProviderList) that does not exist insrc; the mode-mapping rollback is already tested (ClineProvider.spec.ts:6623/6637,6948/7003); the dispose flush trade-off is real and the tests that pin it areClineProvider.spec.ts:4862-4865,4882,4894-4896,4918, not the files the review cites. They are with the maintainer for disposition, so no reply was posted on them yet.CI at this head is not green: the org commit view carries the reconcile and resolve bookkeeping checks with

a63981380)Thread 2 (
rt4477271618, dispose flush). Measured before changing anything: nothing at launch drops temporary-id entries -nextViewIdis declared atClineProvider.ts:325and consumed at 587 and nothing else recognises the shape - whileloadViewState(1144) refuses to read such an entry back andprunePersistedViewStates(1044) sorts newest-first and slicesMAX_PERSISTED_VIEW_STATES(326). The dispose write therefore stored a record nobody can load, at the cost of a slot that outranks loadable entries at eviction. Teardown now drops the held change and theforceUnregisteredWriteoption goes with its only caller. The flush-asserting test is replaced by one asserting the change is dropped and nothing reaches storage; the test whose subject was a teardown flush that fails is deleted. Control: against the previous provider the replacement test fails withexpected { 'sidebar-293': { ...(2) } } to deeply equal {}.Thread 3 (
rt4477271629, mode mapping compensation). The previousactivationModewas a function-local with a single assignment, so a mode change inside the window did not retarget the rollback; the real gap was the gate - the sibling snapshot at 3424 is awaited before the mapping write is issued, so a failure there replayedsetModeConfig(mode, undefined)and cleared a mapping the call never touched. The rollback is now gated on and replayed from a record created when the write is issued (3435, gate 3508). Tests: the pre-issue case fails on the previous code (setModeConfigcalled once when it should not have been called at all); the two mid-window tests (mode set after capture, shared mode cleared after capture) pass unchanged today and their control - a rollback that reads the live mode - reddens them together with the existing rollback test.Lanes on the committed text:
ClineProvider.spec.ts474 passed (baseline at375e25546was 472),webviewMessageHandler.spec.ts174,ClineProvider.sticky-profile.spec.ts25,ClineProvider.sticky-mode.spec.ts29. eslint--max-warnings=0exits 0 on both touched files,eslint-suppressions.jsonis unchanged at 3298 total,tsc --noEmitexits 0, prettier is a no-op on the committed text. The sibling-snapshot helper family also carriessharedStoreCarriesProfileRecordon vps2-f2a (2b7a41d58) and vps2-f2c (e8b2ac051); this branch does not carry that predicate and this head does not add a third version of it.Threads 4 (
rt4477271636) and 5 (rt4477271646) were answered with measurement and resolved without a code change: thread 4 asks for an ownership check that already runs on the path it names (removeOwnRenameRecord,webviewMessageHandler.ts:2563-2574, exercised bywebviewMessageHandler.spec.ts:2791-2827), and thread 5 would make a derived mirror authoritative for an operation that works on the manager record, withprovider.syncProviderList()not existing anywhere insrc.Review round 3 - parked rows naming #1550 from #2235 and #2236 (75add35)
Four review rows parked on #1550 as owner. Each was measured against a639813 before deciding, then answered in-thread.
Controls and gates. Both new tests are red at a639813 (the crafted map replaced the seeded sibling entry; the loop called contextProxy.setValue for viewStates) and green at 75add35. Committed-tree lanes: ClineProvider.spec.ts 475 passed, webviewMessageHandler.spec.ts 175, sticky-mode 29, sticky-profile 25, ContextProxy 64, importExport 55, api-start-new-task 6, api-start-task-logging 8. The compile job's own command list was run in job order: lint, check-types, test:code-qa-ci, solheim-smoke:check-types, test:agent-evals:unit, agent-evals:check-types, lifecycle:model-check, webview-recovery:check-types, webview-recovery:model-check and mcp:integration-check all exit 0. format:check is red locally on 2005 files and none of them is a file this PR touches: they carry CRLF in the working tree while every blob is LF (14 of 15 sampled flagged files have CR, blob CR 0), and the same blobs re-checked after LF normalisation pass prettier --check, so the local red is an artefact of the checkout, not of the head. test:solheim-smoke-ci (18) and test:solheim-smoke:unit (1) are box-local too: record.sh needs ffprobe/ffmpeg, absent here (the 127 vs 143 assertions are command-not-found against a SIGTERM code), and config.test.ts:54 asserts the POSIX path /tmp/isolated/.config against this box's backslash form. ESLint suppressions unchanged at 3298. Threads on #1550: 0 unresolved of 71; the verdict is still CHANGES_REQUESTED, which only a review can clear.
Review round 4 - the third door on this boundary (138b147)
Restating the viewStates row as an API-surface row prompted a measurement of the API surface, and the boundary had three doors rather than two. Door inventory at this head, stated so two guards are not read as a closed boundary:
The read side stays open deliberately and is recorded as open: getConfiguration (src/extension/api.ts:626-629) returns getValues() minus secrets, so an API caller can still read the registered map. Reading it is not the hazard the finding describes, and guarding it would change what existing callers see for no defect shown. So on this head the boundary is closed at all three write doors and open at one read door.
Test and control: src/extension/tests/api-configuration.spec.ts pins that setConfiguration({ viewStates: {...}, soundEnabled: true }) calls contextProxy.setValues and saveConfig with { soundEnabled: true } only and logs the ignore; it is red at 75add35 without the drop (setValues received the crafted map) and green with it. Lanes on the committed text: api-configuration 10, api-delegation-events 6, api-delete-queued-message 3, api-has-task-ui-message-text 8, api-send-message 6, api-start-new-task 6, api-start-task-logging 8, api-task-conversation-history-length 23, api-terminal-profile 1, api-theme-fixture 2, displaySettings 22, ClineProvider 475, webviewMessageHandler 175, all passing; src tsc --noEmit exit 0; neither touched file carries an eslint suppression and the total held at 3298. The compile-job command list was run again in job order with the same results as round 3: green at lint, check-types, code-qa-ci, solheim-smoke check-types, agent-evals unit and check-types, lifecycle model-check, webview-recovery check-types and model-check and the MCP OAuth check; format:check red locally on 2004 files, none of them touched here (working-tree CRLF against blobs whose CR count is 0, and the touched files pass prettier --check after LF normalisation), and the two solheim record.sh suites still need ffprobe and POSIX path separators, which this box lacks.
Review round 5 - assertion strength on the same guard (696aa22)
The last live row on this PR was a test-strength finding on the round-3 handler case, and it was right:
expect.anything()excludesundefinedandnull, so anot.toHaveBeenCalledWithon the key plusexpect.anything()passes even if the updateSettings loop wrote the key with an undefined value - the shape that erases the registered map, since ContextProxy reads an undefined value as a delete. The shipped guard (src/core/webview/webviewMessageHandler.ts:790) drops on the key regardless of value, so behaviour was never wrong; the gap was that the assertion could not see the erase, and the same file already pins the undefined shape for another key at:2109-2116, which makes the weaker form easy to copy.696aa22 adds
webviewMessageHandler.spec.ts:2148-2162: an unsetviewStatesalongside a real setting must produce no write for the key - neither the undefined value nor the Anything matcher - must still write the other key, and must log the ignore. Control: guard block removed gives 2 failed | 174 passed with this case failing on[ 'viewStates', undefined ]; guard in place gives 176 passed, exit 0. Test-only change, no behaviour touched. The asymmetry between the two doubles is recorded in the commit message because it generalises: the provider-side test is erase-safe for free because it asserts on stored state (ClineProvider.spec.ts:9038-9040), while the handler double is a baresetValuemock and must pin the call and its value.Gates on this head: handler spec 176 passing on the committed text, src tsc --noEmit exit 0, eslint clean with the file's single entry unchanged at 35 and the suppressions file byte-identical to its blob at 3298, and the compile-job command list reproduced the round-4 result exactly (green everywhere except the two box-local reds: format:check on 2004 locally-CRLF files, none of them the file touched here, and the two solheim record.sh suites that need ffprobe and POSIX separators). The three write doors named above are untouched by this commit; it strengthens the evidence behind door 1.
Review round 6 - the explicit unset at the API door (d19bb3f)
The live row on this head asked for the unset shape at the API boundary, and it was right:
withoutInvalidDisplaySettingsfilters throughObject.entries, so a key holdingundefinedsurvives it and reaches both writes, and ContextProxy reads an undefined value as a delete.api-configuration.spec.ts:109-137now pins thatsetConfiguration({ viewStates: undefined, soundEnabled: true })leaves bothcontextProxy.setValuesandproviderSettingsManager.saveConfigwith an object that strictly equals{ soundEnabled: true }, against the profile namedefault, and logs the ignore. Control: the guard block atsrc/extension/api.ts:645-656removed gives 2 failed | 9 passed with this case red onexpected { viewStates: undefined, ... } to strictly equal { soundEnabled: true }; guard in place gives 11 passed, exit 0.Worth recording because it decides whether a case in this family has teeth:
toHaveBeenCalledWithcompares the waytoEqualdoes and ignores undefined-valued keys - measured here with a throwaway probe - so assertions written only in that form pass on an unwritten drop of an unset. The strict assertions on the captured arguments are what bite; the loose ones stay beside them. Test-only change, gates unchanged from the previous heads (compile-job list 1,0,0,0,1,1,0,0,0,0,0,0,0 with the same two box-local reds), api-configuration 11 / displaySettings 22 / ClineProvider 475 / webviewMessageHandler 176 on the committed text.
