Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1559 (this series' gap record; the original upstream bug is #978). Port source: the F1c-head-to-CS residual, cross-checked against upstream PR #979 (fix(webview): isolate parallel mode and provider profile writes) — closed/superseded by the vps2 series; the fork issue 41 ledger names #979 as the F3 port source.
src/core/webview/ClineProvider.ts — the webview delete-path (deleteProviderProfile + repointPersistedViewStates), loadViewState dead-mode-pin validation, the handleModeSwitch profile-write isolation (per-view upsert/activate instead of the shared write), the as-any cast drop in delegateParentAndOpenChild, and a 3-line Stryker exclusion comment above the no-op listApiConfigMeta view-state write (two equivalent mutants). This round also: dispose() runs every cleanup step independently (per-step try/catch, first error preserved and rethrown after all steps run, individual disposables isolated) — the CR Major finding fix; and the F1a view-identity review fixes are ported into this unit's copy (temporary-id authorship flag, ownsTargetEntry re-key gate, null-prototype viewStates, loadViewState ownership guard, setValue/setValues rollback).
src/core/task/Task.ts + Task.spec.ts — the task-side per-view mode/profile write: mode switches route through provider.handleModeSwitch and the submitted message is kept on failure.
src/core/tools/SwitchModeTool.ts + switchModeTool.spec.ts — the tool-side per-view write port.
src/core/webview/webviewMessageHandler.spec.ts — ported mock surface only (4 mock fields + defaultModeSlug import); webviewMessageHandler.ts itself is 0/0.
sticky-mode / ClineProvider / parallelMode specs — per-view assertions, the CS F3 describes, and the mutation-killing tests; this round the sticky-mode persisted-view-state-keys suite, rollback tests and the re-key ownership adaptations are ported in, and every ClineProvider construction passes the shared WebviewFocusTracker.
src/extension/tests/api-set-configuration.spec.ts — passes the required ClineProviderFactory argument (main's new constructor parameter).
Upstream main 793b65b merged (this round): 5 conflicts reconciled both-sides — openClineInNewTab keeps the serialized flow on main's typed options + shared tracker; getState keeps the per-view mergedStateValues reads including main's new alwaysDenyUnapprovedCommands; the non-await postMessage path keeps the original-content strip.
Budget
Unit delta vs the stack base: 10 files, +919/-65 (a+d 984 vs the 400-soft / 1000-hard budget: soft-over, hard-under; the unit carries the production isolation logic). The PR diff vs upstream/main is 33 files (+9186/-511) because the branch is stacked on the unmerged F1-F2 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.
vitest run src/core/webview/__tests__/ClineProvider.spec.ts -t "active instance tracking" — dispose step isolation (early-step failure runs later releases and reports the first error).
vitest run src/core/webview/__tests__/ClineProvider.sticky-mode.spec.ts — per-view viewStates keys + the ported persisted-view-state-keys suite.
vitest run src/core/tools/__tests__/switchModeTool.spec.ts src/core/task/__tests__/Task.spec.ts — tool/task-side per-view writes.
vitest: ClineProvider.spec 288/291 (the 3 failures are local-only: the donor-built @roo-code/types dist predates alwaysDenyUnapprovedCommands, so globalSettingsSchema strips it locally; CI builds types from source); sticky-mode + registerCommands + parallelMode + webviewMessageHandler + flicker-free-cancel + api-set-configuration 221/221; webview-ui ExtensionStateContext 25/25; packages/types global-settings 9/9.
eslint --max-warnings=0 clean on all touched files; eslint-suppressions ClineProvider.spec.ts 196 -> 194 (decrease), no count increased.
Negative controls: flipping the first-error guard in the new cleanupStep reddens both dispose tests; forcing the re-key ownership check to true reddens sticky-mode "does not merge a stale temporary-id entry"; both restored byte-exact (sha256 match).
Prettier: full-repo check passes on the PR merge tree (merge ref cddc7d7).
Fixed the CR Major finding: dispose() cleanup steps are now isolated (per-step try/catch, first error preserved and rethrown after all steps run, individual disposables isolated); new regression test "runs every later cleanup step when an earlier step rejects" (mcpHub.unregisterClient rejects; customModesManager.dispose and taskHistoryStore.dispose still run); existing cleanup-failure test updated for the per-step log wording. Thread replied and resolved.
Ported the F1a view-identity review fixes into this unit's ClineProvider copy; adapted the three re-key tests to author entries through the real write path; ported the sticky-mode persisted-view-state-keys suite, rollback tests and the viewStates global-setting tests.
Added the required WebviewFocusTracker constructor argument to the 88 ClineProvider.spec and 40 parallelMode.spec constructions; api-set-configuration.spec passes the required ClineProviderFactory.
Unit-delta local Stryker preflight was certified at the pre-merge head; the stacked CI mutation-diff reports a changed-line cap artifact by construction (inherited shared content). The dispose-isolation change is covered by the two dispose tests plus the negative control above.
Series mechanics
PR base is main; the branch is stacked on the F2 head; merge order F1a -> F1b -> F1c -> F2 -> F3 -> F4 -> F5 -> F6 -> F7.
CS not-ported register (for consistency): kimi-code OAuth try/catch + routerModels.spec +29; ApiConfigManager min-w-0->grow; ApiConfigManager.visual.tsx deletion + 2 PNG baselines; mojibake comment; providers/, .coderabbit.yaml, .github/, CONTRIBUTING.md, .gitignore churn — none of these touch the files in this PR.
Security Boundaries / view-state id rows: addressed at 9c2bee3. setViewStateId now rejects non-string ids (crafted postMessage), bounds the key length (MAX_VIEW_STATE_ID_LENGTH), and refuses ids already owned by another live instance; a refused view stays on its temporary id against shared state. Regression tests: non-string, oversized, claimed-by-another-view. Negative controls: disabling the ownership check reddens exactly the claim test; widening the length bound reddens exactly the oversized test; restores byte-exact (hash match).
The spec gained an afterEach clearing the static instance registry (suites construct providers directly and never dispose most of them; leaked instances would claim ids ahead of later tests).
Persistence Integrity setValues/setValue ordering rows: verified already addressed by the pushed code: _saveViewLocalStateFromMutation persists the non-secret subset before updating the buffer; the re-key is a single queued write (no delete-then-write window; authorship clears only after the write lands); the mutation hook keeps the buffer synced across setValue/setValues and profile upsert/activation/deletion.
Proofs at 9c2bee3: 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 fe00539: 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 a5a2f60)
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 b68744c)
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 390c0d4)
A review round on this unit produced three fixes. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
The fallback deletion path's re-check of whether this view pinned the deleted profile was unreachable (a view pinned to the deleted profile takes the activation path above and returns); the dead branches are removed, behavior-preserving (spec green).
A review round on the mode-profile-writes unit found that the profile-deletion re-pin updated each sibling view's buffer but not its running task: the posted state prefers the task's own apiConfiguration, so a conversation in a view pinned to the deleted profile kept sending the deleted profile's settings. The re-pin now rebuilds the sibling's API handler with the replacement's settings and re-points the task's sticky profile name, mirroring the activation path.
Proofs: ClineProvider.spec and sticky-mode green; eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED. The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.
Proofs: ClineProvider.spec 293/293, sticky-mode 34/34 (new pin-write-failure rollback test), parallel-mode 34/34 (sibling re-pin test asserts the task handler rebuild and sticky-name re-point); negative controls: dropping the rollback call reddens exactly the rollback test, dropping the rebuild reddens exactly the re-pin test, restores byte-exact (hash match); eslint --max-warnings=0 clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.
Updated this round (CodeRabbit follow-up, head 08c6fcb)
Mode-switch atomicity (ported from the sibling unit): handleModeSwitchUnlocked reconciles every write it owns (shared mode, durable view pin, task mode, task history) when a failure lands after the task-mode write - including the mode-linked profile activation - so submitUserMessage delivers the submitted message on the pre-switch mode and profile instead of a half-applied switch; regression test included.
Non-activating profile saves no longer force-rebuild the API handler of a view whose active task follows a different sticky profile (both rebuild sites guarded by taskApiConfigName); regression tests cover both sites.
Test hygiene: prune assertions compare full kept entries; the two re-key storage tests seed through the durable write path so their assertions can fail; sticky-mode afterEach disposes the per-test provider before resetting the instance registry; the webview state-payload test renamed to describe what it asserts.
Verified: ClineProvider.spec, sticky-mode and parallelMode suites green, eslint --max-warnings=0 clean, tsc real=0, prettier clean; negative controls: removing either rebuild guard reddens exactly its test, reverting the reconcile reddens exactly the activation-rollback test.
Updated this round (CodeRabbit follow-up 2, head c820dd0)
Deleted-profile re-pin: the forced task-handler rebuild and the sticky-name rewrite now require taskApiConfigName === deleted profile (the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.
Updated this round (CodeRabbit follow-up 3, head 0b08bb0)
Mode-switch reconcile: the rollback is skipped once the mode-linked activation has started writing shared state (a mode-only rollback would pair the old mode with the new profile), and also when the mutation signal has aborted (the queue has advanced; a newer mutation may own the mode stores - this is the fix requested on the PR thread). The trailing state post now runs outside the reconciled region - a UI-refresh failure after a committed switch is logged, not rolled back. Three regression tests included (negative controls: removing either guard or re-throwing the post reddens exactly one test each).
Updated this round (CodeRabbit follow-up 4, head 0d1e16a)
Mode-switch events now match the stores: ModeChanged is emitted only after the switch commits (a reconciled failure no longer leaves listeners on the rolled-back mode), and the rollback re-emits TaskModeSwitched with the restored mode for API/IPC consumers. The lock path no longer posts inside the reconciled region (it falls through to the committed-switch tail, where a post failure is logged). The mode-default recording reads the view's effective profile (getValues overlay) instead of the shared slot, so a sibling view's activation cannot become this mode's default. Three regression tests included (negative controls: each mutation reddens exactly its test).
Updated this round (CodeRabbit follow-up 5, head 9f62b84)
The committed-switch guard now flips only when the activation has actually written the activated profile (onSharedWriteStart callback), so a mode-linked activation whose own profile lookup fails (deleted profile) still reconciles the switch. The catch that keeps a switch (activation had written, no abort) now emits ModeChanged and posts state before rethrowing, so listeners and the webview learn the committed mode; the abort branch intentionally stays silent (a newer mutation may own the fields - documented in code). In-try abort checkpoints after the mode writes no longer return silently: they fall through to the emit/post tail so the committed mode reaches listeners and the webview. Three regression tests; negative controls: each mutation reddens exactly its test. The activation-failure test double now mirrors the onSharedWriteStart flip.
Updated this round (CodeRabbit follow-up 6, head 8d33d13)
Abort-silence rule settled: the emit/post tail announces a switch only while its committed mode is still current (after an abort, the tail checks the effective mode store; a superseded commit stays silent because the newer mutation already announced its own mode). This keeps both invariants: a committed switch is never left un-notified while it is current, and no stale announce clobbers a newer owner. Regression tests cover both branches (still-current -> emitted; superseded -> silent); negative controls: dropping the guard reddens the superseded test, always-silencing reddens the still-current test.
Updated this round (CodeRabbit follow-up 7, head 5ee6bcb)
The lookup-failure regression test now exercises the REAL activateProviderProfileUnlocked (providerSettingsManager.activateProfile rejects) instead of a stub, so the production placement of the committed-switch flip (only after activateProfile resolves) is covered; a matching test keeps the switch when activateProfile resolves and a later shared write (setModeConfig) rejects. Negative controls: moving the flip above the activateProfile await reddens exactly the rollback test; removing it reddens exactly the kept-switch test.
Updated this round (CodeRabbit follow-up 8, head 6e583d0)
The kept-switch regression test now also pins the task-side state on the committed mode: the task's in-memory mode stays architect and the last task-history write carries mode architect (a trailing rollback of the task-side writes after the committed-switch point would now be caught). Negative control: an extra history write with a different mode in the kept branch reddens exactly this 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
Stryker disable next-line ConditionalExpression: only tool_use and mcp_tool_use entries ever carry an id — the text block pushed in the text case has no id field and the start events reaching this guard always carry the string id locked in by processRawChunk — so the type check cannot change the outcome of entry.id === event.id for any entry this pipeline produces; the false replacement is additionally killed by the rejection tests.
Stryker disable next-line ConditionalExpression: event.name is always a string on this path — the only delta events reaching this handler are emitted by processRawChunk with the tracked start name (never undefined), so the legacy nameless branch below is unreachable defensive code and the conditional always takes the named side.
Stryker disable next-line ConditionalExpression: streamingKey can never be undefined here — makeStreamingKey always returns a string and the legacy lookup branch above is unreachable (see the directive on the event.name check) — so the null side is unreachable defensive code.
Stryker disable next-line ConditionalExpression, EqualityOperator: streamingKey is always a defined string on this path (makeStreamingKey never returns undefined; the legacy branch is unreachable per the directives above), and processStreamingChunk returns a partial ToolUse for a known key, so both defensive conditions reduce to the partialToolUse check and cannot change the observed behavior.
Stryker disable next-line LogicalOperator: event.name is always a string on this path — finalizeRawChunks emits end events with the tracked start name (a string, set before the tracker can start), so the ?? event.id fallback guards a nameless end event this pipeline cannot produce.
Stryker disable next-line ConditionalExpression, LogicalOperator, EqualityOperator: the both-miss case is unreachable via the raw-chunk pipeline — end events carry the locked start name so the compound key resolves the registered entry, and a same-ID rejected-start end is always processed after the accepted start's end has already removed that entry; this defensive path protects against a cross-name end event the pipeline cannot produce.
Stryker disable next-line ConditionalExpression: unreachable defensive region — getStreamingToolCallById can only resolve when the both-miss case above is reachable, which the raw-chunk pipeline cannot produce (see the directive there).
Stryker disable next-line CallExpression,ObjectLiteral: _updateViewLocalStateFromMutation applies only mode, currentApiConfigName, apiConfiguration and provider-settings keys, so a listApiConfigMeta-only payload (deleted call or empty object) is a behavior-preserving no-op.
Stryker disable next-line ConditionalExpression: dropping this term admits only undefined-pin instances, which the callback's pin guard absorbs (returns before any write); the filter-to-guard chain is synchronous (equivalent mutant)
Stryker disable next-line ConditionalExpression,BlockStatement: guard body unreachable - the filter predicate guarantees a defined pin and the filter-to-guard chain is synchronous (equivalent mutant)
Stryker disable next-line ConditionalExpression,BlockStatement: hostile non-stabilizing encodings are unreachable from the webview (its posts are plain link targets); the bound is defensive
Stryker disable next-line CallExpression: hostile non-stabilizing encodings are pinned by the direct decodeUntrustedPathToStable bound test; the webview never posts such values
Stryker disable next-line ConditionalExpression,OptionalChaining: equivalent mutant - when localStorage is unavailable the guard-false path and the throwing body both return this.fallbackState from this catch
Stryker disable next-line ConditionalExpression,OptionalChaining: equivalent mutant - when localStorage is unavailable the guard-false path and the throwing body both mark the write failed and return newState
CR round 2026-10-15 (b)
SwitchModeTool now reports an error result (and records the failure) when the provider reference is released before the switch executes, instead of a false success; the released-provider test asserts the error result.
setValues now validates mode against custom modes carried in the same payload (createTask/setConfiguration register them only after the call), so a brand-new custom mode in the payload is no longer dropped. Regression test added; the identical block in the sibling units received the same fix.
CR round 2026-10-15 (e)
Ported: createTask restores the previous mode selection when custom-mode registration rejects (identical flagged block; regression test added).
CR round 2026-10-15 (f)
The createTask registration-failure rollback now restores the shared mode and the view's own mode pin independently (unset pin stays unset); divergent-pin regression test added. Same fix in all six units carrying the flagged block.
Activation writes from the stored record: upsertProviderProfile reads the saved profile back after saveConfig and feeds the normalized record to every post-save consumer (CR Security Boundaries).
Clear/re-point cache rollback: both durable viewStates writers restore the cache to the durable value when the write rejects, before rethrowing (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.
Editor tabs now have dedicated controls for creating tasks, opening settings, browsing the marketplace, and viewing history.
View-specific mode and profile selections are saved and restored independently across webviews.
Bug Fixes
Tab actions and mode changes now apply to the intended task or view, with clearer handling when an action cannot be completed.
Settings import and export no longer transfer view-specific state, helping preserve local selections.
The PR adds per-view state identity and persistence, updates profile and mode handling, adds rollback for configuration updates, and separates editor-tab command routing from sidebar commands. It also updates related tests and repository maintenance files.
Changes: Per-view state and profile operations
Layer / File(s)
Summary
View identity and state transport packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, packages/types/src/__tests__/*, webview-ui/src/utils/vscode.ts, webview-ui/src/utils/__tests__/vscode.spec.ts, webview-ui/src/context/ExtensionStateContext.tsx, webview-ui/src/context/__tests__/ExtensionStateContext.spec.tsx
Global settings support validated viewStates entries, and launch messages carry a view-state ID. The browser wrapper validates persisted IDs and maintains fallback state when storage is unavailable or fails.
State portability and launch recovery src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/*, src/core/webview/webviewMessageHandler.ts, src/core/webview/__tests__/webviewMessageHandler.spec.ts
View state is excluded from settings export, import, and renderer-supplied settings writes. Launch handling registers view state and repairs invalid profile selections.
Provider settings add missing-profile identification, mode-mapping deletion, and a combined selection-and-mapping read. Profile rename and Zoo Code sign-out use provider operations with compensation or per-profile failure handling. Mode tests cover view-local persistence, rollback, cancellation, and concurrent changes.
Configuration update and rollback src/extension/api.ts, src/extension/__tests__/api-configuration.spec.ts, src/extension/__tests__/api-set-configuration.spec.ts
Configuration updates save the profile before applying settings and mode mappings. If a later step fails, the code attempts to restore prior profile data, settings, mappings, and affected overlays. Webview state is posted after successful updates.
Task-scoped mode switching
Layer / File(s)
Summary
Task-scoped mode switch calls and validation src/core/task/Task.ts, src/core/task/__tests__/Task.spec.ts, src/core/tools/SwitchModeTool.ts, src/core/tools/__tests__/switchModeTool.spec.ts
Task message submission and the mode-switch tool pass the target task to the provider. Tests cover applied and rejected switches, provider unavailability, and message delivery. Removed Stryker suppression comments do not change the associated native tool-streaming logic.
Editor-tab command routing
Layer / File(s)
Summary
Tab commands and action routing packages/types/src/vscode.ts, src/package.json, src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts
Four tab-specific commands are contributed for editor-title actions. Sidebar and tab commands target their respective providers, and action-post failures are logged individually.
Tracked panel creation and lifecycle src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts
Overlapping tab opens share creation while a provider is live. Activation and disposal update tracked-panel selection; failed webview resolution disposes the panel and provider while preserving the original error.
Repository and test maintenance
Layer / File(s)
Summary
Ignore patterns and locale test synchronization .gitignore, webview-ui/src/i18n/__tests__/TranslationContext.locale-loading.spec.tsx
Ignore patterns cover additional generated text files. Locale tests await the language-loading promises recorded from the provider.

Security Architecture Review
Security architecture risk:🟡 Moderate · up to d2faa
Parallel views can select different provider profiles, but overlapping profile changes may leave a view showing one profile while using settings from another. The affected scope is the extension's views and configured provider connections, not a demonstrated cross-user or cross-tenant boundary.
Retained concerns
Medium · security · inferred: Overlapping profile activations can leave a view pinned to one profile name while its configuration falls back to another view's shared provider settings. A local overlay is also merged over, rather than substituted for, those shared settings. This can undermine the intended isolation of provider credentials and destinations across parallel views.
Low · architecture · inferred: Launch registration accepts a renderer-supplied view ID without binding it to the receiving view. If a renderer supplies another valid ID, it can load and later write that ID's persisted mode or profile pin. Practical targeting depends on learning or colliding with an ID; this does not establish new access to profile secrets, which existing renderer commands can already select.
Security review details
Security Blast Radius
inferred — The independently affected scope is multiple views in one extension host and their configured provider connections. A profile/settings mismatch could cause a view or subsequent task to use an unintended provider configuration; the evidence does not establish cross-user, cross-tenant, or deployment-wide exposure.
Security Findings and Attack Paths
inferred — Two live views can initiate overlapping profile activations. Because their mutation queues are separate, one activation can clear its own overlay after the other has taken a sibling snapshot, leaving its pinned name backed by the final shared settings. No concurrent two-provider activation test or runtime trace was available to establish frequency.
Trust Boundaries and Controls
observed — Launch forwards a renderer-provided ID into state restoration. Sanitization, random default IDs, stale-load checks, and invalid-mode handling constrain the path, but none binds a supplied valid ID to its view. Existing renderer profile-selection commands limit any claim of newly gained secret-reading authority.
Resilience and Maintainability Implications
observed — Serialized persisted-state writes, stale-load suppression, focused-task gating, and sibling refresh provide meaningful counterevidence for ordinary sequential operation. They do not establish atomic cross-view profile activation or recovery from a partially completed activation.
Hardening Proposals
proposed — Keep the selected profile name and complete configuration together as a view-owned value, or serialize shared-setting replacement across providers and reconcile overlays after failure. Bind stable-ID restoration to the receiving view rather than treating a sanitized renderer-supplied ID as ownership proof.

Full details: Title check
Explanation
The title names the fix type (fix), the affected area (webview), and the core change (isolating parallel mode and provider profile writes). The diff matches this: per-view mode and profile write isolation across ClineProvider, Task, SwitchModeTool, the API configuration path, and their tests. The 'vps2 F3' tag is an internal series label that adds noise, but the title still describes the primary change. It does not cover every detail, which the criteria allow.
Full details: Description check
Explanation
The description is long and detailed. It covers the changes, the test procedure with specific commands and results, and extensive verification notes. It also lists series mechanics, upstream merges, and review-round fixes. Against the template, several items are weak or missing. The 'Related GitHub Issue' section links to a fork issue (41) and an upstream issue (#1559), and it does not use the required 'Closes: #' format for an approved issue. The 'Pre-Submission Checklist' is not marked. The 'Documentation Updates' section is not answered. The 'Get in Touch' section has no Discord username. The description also contains a long, layered history of follow-up rounds that makes the 'what' and 'why' hard to find. Its prose also uses many contractions-free but dense, compound sentences, which conflicts with the repository's Simplified Technical English guidance. The core content is present, so the check does not fail. The gaps are real and need fixing.
Resolution
Fix the Related GitHub Issue section so it uses the required 'Closes: #<number>' form and points to an approved issue. The fork issue and the upstream draft references do not meet the 'approved issue' rule as written. Mark the checklist items that apply. Answer the Documentation Updates section. Add a Discord username in Get in Touch. Condense the Description to the 'how' and the key review points, and move the long round-by-round history out of the main body. Also check that the description follows the Simplified Technical English guidance.
Full details: Security Boundaries
Explanation
The prior security finding remains unresolved. webviewDidLaunch passes renderer-controlled message.viewStateId to setViewStateId (src/core/webview/webviewMessageHandler.ts:603-615). setViewStateId checks format and live-instance collisions, but it does not bind the ID to the host-created WebviewPanel or WebviewView (ClineProvider.ts:919-975). dispose() removes the provider from activeInstances (ClineProvider.ts:1601), so a disposed view ID becomes reusable. A stale or compromised webview that knows that ID can cause loadViewState() to call getProfile() and copy the complete profile, including fields such as apiKey, openRouterApiKey, awsSecretKey, and zooSessionToken, into viewLocalState (ClineProvider.ts:1025-1032). Launch then posts state, and getState() uses that unredacted view configuration (ClineProvider.ts:5034-5045; getStateToPostToWebview() at 4610-4782). This changed path can disclose another view's provider credentials.
Resolution
Bind each persisted view-state ID to the exact host-created WebviewPanel or WebviewView, and require that binding during webviewDidLaunch. Reject disposed, unowned, or mismatched IDs before loadViewState() and before posting state. Redact API keys, tokens, OAuth credentials, AWS credentials, and all other secret provider fields from apiConfiguration sent to the webview. Add a regression test that submits a disposed or unowned ID and verifies that the profile is neither loaded nor posted.
Full details: Persistence Integrity
Explanation
A changed persistence path remains non-atomic. handleZooCodeCallback now routes non-active profiles through upsertProviderProfile(..., false) (src/core/webview/ClineProvider.ts:4152-4155). That path saves the profile at 3227, then writes profile metadata and view-local state at 3321-3340. If the metadata or view-state write fails after saveConfig succeeds, no compensation restores the profile or prior state. upsertProviderProfile catches the error and returns undefined (3089-3095), so the caller can continue with a partial durable update. The activation path has the same gap: Promise.allSettled waits for its writes at 3289-3307, but it throws without compensating successful list, selection, mode, shared-settings, or view-state writes. ContextProxy.setValues is explicitly non-transactional (ContextProxy.ts:672-701).
Resolution
Make persistProviderProfile transactional for both activation modes. Snapshot the prior manager record, profile metadata, selection, mode mapping, shared provider settings, affected view-state entries, and task/view-local state before saveConfig. Await all writes and post-save refreshes. After any failure, compensate every write that landed through its serialized store, await each compensation, and report compensation failures. Do not return undefined while the new profile or partial activation state remains persisted.
Full details: Regression Evidence
Explanation
The prior regression remains unresolved. VSCodeAPIWrapper.getState() has changed fallback branches at webview-ui/src/utils/vscode.ts:121-130 for undefined localStorage, a storage object without getItem, and malformed JSON. The focused suite tests a throwing getItem() and unavailable setItem(), but it does not exercise those three branches directly. Regressions in the unset and malformed-state paths can pass undetected.
Resolution
Add focused tests in webview-ui/src/utils/__tests__/vscode.spec.ts for undefined localStorage, a storage object without getItem, and malformed JSON from getItem(). In each test, assert that getState() does not throw, repeated getViewStateId() calls return one generated ID, and the in-memory fallback remains authoritative.
Full details: Lifecycle Resource Cleanup
Explanation
Unresolved lifecycle leak remains. The changed handleModeSwitch path calls enqueueProviderProfileMutation(..., { runToCompletion: true }) at src/core/webview/ClineProvider.ts:2669-2675, so a timed-out switch continues running. dispose() sets _disposed and cancels only taskScheduler at :1486-1500; it does not abort or close providerProfileMutationQueue. The queued callback checks only signal.aborted, which disposal never sets. If disposal occurs while a mode switch is blocked, the active or queued callback can later perform task-history, view-state, shared-mode, profile, and webview-state work. The added timeout test verifies queue ordering but does not cover disposal.
Resolution
Make provider disposal close providerProfileMutationQueue, reject queued callers without running their callbacks, and abort or await the active mutation with disposal-aware rollback. Check _disposed before queued callbacks and before each task, profile, shared-state, and view-state write after an await. Add a regression test that blocks one mode/profile mutation, queues a second, disposes the provider, releases the first, and verifies that the second performs no writes.

…en view-identity tests
Track the in-flight tab panel creation with a module-level promise so concurrent openClineInNewTab calls reuse one panel and provider (adds a Promise.all regression test). ClineProvider.spec sets the private view via the public resolveWebviewView() instead of a ts-ignore assignment. registerCommands.spec types evictCurrentTask/refreshWorkspace on the fixture and drops the as any attachment. eslint-suppressions: prune the registerCommands.spec.ts entry (two as any suppressions removed).
…-bar posts
- openClineInNewTab: extract the unserialized creation body into
createTabPanelUnlocked and guard the in-flight slot clear so a settled
creation cannot clobber a replacement already stored in the slot.
- onDidDispose: clear the tracked tab ref only when the disposing panel is
still the tracked one, so a late disposal of a replaced panel cannot
clobber the replacement's ref.
- MDM lookup failure: log the fallback to the output channel instead of
swallowing it silently.
- Route the six title-bar button handlers through a shared postActions
helper that posts each action in order and logs failures with the
handler-specific prefix.
- package.json: add the four InTab commands to the command palette, scoped
to the active tab panel.
- Tests: handler-level regression for openInNewTab + popoutButtonClicked
started before the first creation resolves; fresh-creation test for a
settled in-flight promise; stale-panel disposal regression; retained
panel assertion for disposed tab instances; rightmost-editor column
placement assertion; MDM fallback output assertion; %s placeholders for
primitive it.each titles.
- Stryker directives for the two equivalent setPanel type-literal mutants
(setPanel branches only on type === sidebar).
Replace the weak toBeDefined() assertion in the dispose spec with an
identity check against the panel returned during creation, per the
CodeRabbit actionable comment on this PR (review run 7c4cfeb3-6dd9-4615-
9a58-70cfc705eca2). The tracked tab is now pinned with toBe(panel)
before the dispose assertions, so a wrong or duplicated tracked panel
fails the suite instead of passing a defined-only check.
Upstream: Zoo-Code-Org#1528 (vps2 F0)
Retain the tracked tab panel in the InTab handler cases and assert that
getInstanceForView was called with that exact panel, per the CodeRabbit
actionable comment on this PR (review run 4afe1273-8739-4235-90d3-311db5f6ccb9,
inline comment 3952466254 on the tabHandlerCases spec). A handler resolving
any other view now fails instead of passing on the stubbed provider result
alone; the same identity pin is applied to plusButtonClickedInTab.
Upstream: Zoo-Code-Org#1528 (vps2 F0)
…States
Each ClineProvider instance now owns a unique viewId (renderContext plus a
monotonic counter) and registers a stable viewStateId for durable persistence.
- Per-view state buffer (viewLocalState) holds mode / currentApiConfigName /
apiConfiguration overrides in memory; saveViewState persists the non-secret
subset durably under the active view id, rekeyed to the stable id on
registration.
- viewStates is stored as a map pruned to the newest 50 entries; writes go
through a serialized queue so concurrent provider instances merge without
lost updates.
- setViewStateId sanitizes ids and rejects "__proto__" so a per-view entry can
never be keyed through the Object.prototype setter.
- postMessageToWebview no longer awaits the webview ack: a remounted or
disposed page never acknowledges, and awaiting would wedge task-critical
callers.
- History restore falls back to the default mode view-locally instead of
writing the shared global mode.
- GlobalState gains the "viewStates" key and GLOBAL_STATE_KEYS tracks it.
Adds F1a coverage in ClineProvider.spec.ts (viewId uniqueness, saveViewState
persistence semantics, loadViewState fallback and failure, pruning, the
__proto__ guard) and adapts the two history-restore tests in
ClineProvider.sticky-mode.spec.ts to the view-local restore. getState()
merging of hydrated per-view values and the remaining view-state suites land
in the follow-up (F1b).
Panel ERROR rows on this head: the persistence one is closed, the security one is sibling-unit scope — with the parts split out
Panel comment 5564274386 re-evaluated 557f1c9b4 at 02:02Z with 2 errors + 2 warnings. The fix for the Persistence row, and the answers below, are on c79048cf3 (pushed now).
What this unit ships is the pre-capability half, and it is not nothing.setViewStateId is this PR's code: at the merge base 3ee042d91 none of it exists (git show 3ee042d91:src/core/webview/ClineProvider.ts returns zero occurrences of Ignoring a non-string viewStateId, __proto__, MAX_VIEW_STATE_ID_LENGTH and already claimed by live view). What it does today is validate the renderer-supplied value before it becomes a persisted key: a non-string payload is refused; the sanitized result is refused when empty or __proto__ (writing states["__proto__"] goes through the Object.prototype setter and is silently dropped by the later spread); an oversized key is refused, because the webview generates a UUID and an unbounded key is unbounded growth in the shared viewStates map. On top of those four stands the live-instance ownership check: a key another live provider holds is refused, because adopting it would load that view's pinned profile, nested overlay and mode into this provider and let this webview overwrite that view's entry. dispose() deliberately drops the instance from activeInstances while keeping the persisted entry (:1600) — a key that stayed owned by a dead instance would brick every later view — and the retention test pins exactly that behaviour: ClineProvider.parallelMode.spec.ts:774-795 as reviewed, :798-818 at c79048cf3.
Why the claim binding is #2226's, not a second copy here. The row asks for a host-minted claim tied to the exact WebviewPanel/WebviewView that registered it, required during webviewDidLaunch and re-authenticated after disposal and host reload. That capability is the content of #2226 (vps2/n1-view-identity @ 959fd68cf): pendingViewStateClaims at ClineProvider.ts:475, next.claimToken = crypto.randomUUID() at :797-799, claim-less re-binding at :886-897, ViewStateRegistrationResult { adopted, claim } at :270, and deliverPendingViewStateClaims() flushed from webviewMessageHandler.ts:708. Evidence on this branch: git log -S claimToken -- src/core/webview/ClineProvider.ts and git log -S pendingViewStateClaims -- src/core/webview/ClineProvider.ts are both empty, both strings occur zero times in the tree at c79048cf3, and git merge-base --is-ancestor fails in both directions between 557f1c9b4 and 959fd68cf. The two branches edit the same three things — setViewStateId, the webviewDidLaunch registration and viewStates — so minting and validating a token here too would write the contract twice and force a reconciliation at fold-forward. Please assess the ownership half of this row against #2226: nothing here is being waved away, the guards above are what make the pre-capability shape safe until the claim lands.
The secret-redaction half is a separate ask, and scope does not answer it. "Redact API keys, tokens, OAuth credentials, AWS credentials, and all other secret provider fields before returning apiConfiguration to a webview" is not part of the identity contract, is not delivered by #2226, and is not implemented here. This PR changes no redaction: loadViewState() still stores every provider field the manager returns except name (ClineProvider.ts:1024-1032), and getState() / the state-post path still hand the stored configuration to the webview (:4960-4969, :4706-4714), with keys and AWS credentials included (packages/types/src/global-settings.ts:344-381). A claim token shrinks the exposure — a view can no longer adopt an id it does not own — but it does not remove secrets from the state of a view that legitimately owns its id, nor from a compromised renderer that owns one. That decision belongs to whoever owns the webview state contract, and it remains open after this PR and after #2226.
2. Persistence Integrity — the manager gate is now inside the same compensation
Cited: deleteProviderProfile deleting the profile and then activating the replacement (ClineProvider.ts:3400, :3424), activation persisting the manager selection (ProviderSettingsManager.ts:504-510) and the mode mapping (:564-579), and the compensation catch (ClineProvider.ts:3508-3560 as reviewed).
The row is right about the gap and about what is needed, and it is closed at c79048cf3 with the compensation shape this delete path already uses — snapshot before the commit point, restore inside the same catch, rethrow the original — not a fourth shape. What changed:
Snapshot before the delete commits: previousManagerGate = await this.providerSettingsManager.getSelectionAndModeConfigs() plus the id of the profile the deletion is about to activate, read out of the pre-delete entries (ClineProvider.ts:3384-3389), ahead of deleteConfig at :3400.
The read is a new accessor, ProviderSettingsManager.getSelectionAndModeConfigs() (src/core/config/ProviderSettingsManager.ts:599-620). It returns the store's own selection plus a copy of the mode map (modeApiConfigs ? { ...modeApiConfigs } : undefined), it runs inside the manager's existing lock (:108-113), and it adds no write path — nothing in it stores. It exists because listConfig() does not surface the selection, load()/store() are private, and export() schema-parses and filters each config, so it cannot serve as a snapshot read.
Restore inside the same catch (:3556-3591): the selection back through activateProfile, and one setModeConfig per mode whose mapping this deletion actually moved, each gated on the manager still reporting what this deletion wrote — a concurrent activation that took the gate in between is not overwritten — and wrapped in its own catch so a failed gate restore cannot cancel the record, list, selection, settings and pin restores that follow. The original error is rethrown after all of them, unchanged.
Tests, all in ClineProvider.parallelMode.spec.ts: :1507-1597 fails the write after the replacement activation has committed its gate writes and asserts all three surfaces — the secrets-backed record back under its original id, the store selection, and every mode mapping — and also asserts that a mapping which already named the activated id is not replayed; :1602-1705 a concurrent activation that takes the gate between the activation and the failure; :1711-1803 a compensation whose gate read fails outright, proving the restores behind it stay independent; :1809-1866 a delete whose activation target is named by the shared selection but absent from the durable entry list; :1873-1957 a delete that starts with the manager already selecting the profile it goes on to activate.
Negative controls, one per restore leg, each measured (mutate, capture the real failure, restore the file byte-identically, re-run green): replacing the selection leg's first guard with true → expected "vi.fn()" to be called 1 times, but got 2 times; the mode leg's first guard → expected "vi.fn()" to not be called with arguments: [ 'architect', 'doomed-id' ]; its third guard → … [ 'ask', 'test-id' ]; the second guards and the gate-restore log wording likewise. The unit-level mutation preflight on this head (557f1c9b4..c79048cf3, 50 mutants across 4 changed files) reports 0 surviving and 0 uncovered — no Stryker directives and no suppressions were added.
One control did not discriminate and should be recorded: making the accessor return the live map instead of a copy passed the whole suite, because load() re-parses on every call and every read already hands back a fresh object. The copy is kept for the API contract — a caller holding a snapshot across awaits cannot have it rewritten underneath it — not because a test proved it necessary.
The two warnings, for the record. Both are advisory and neither is addressed by this head. The Regression Evidence row wants webview-ui/src/utils/vscode.ts:108-117 covered for undefined globalThis.localStorage, a storage object without getItem, and malformed JSON from getItem(); those are webview-ui package tests and this head does not touch that file. The Lifecycle Resource Cleanup row wants providerProfileMutationQueue invalidated in dispose() with a decision on whether an in-flight mutation with { runToCompletion: true } (ClineProvider.ts:2668-2674) is aborted or awaited; this unit keeps the queue running to completion on purpose (the profile-write unit owns that choice), so the abort-versus-await question is still open and belongs in the dispose-order discussion rather than being settled by a guard added under time pressure.
…ofile-writes
Zoo-Code-Org#2223 landed the time/date format and message-timestamp settings on the same
surface this unit edits, so the branch now carries the merge of main plus this
unit's review fixes in one head. Hand-resolved files:
- src/core/webview/ClineProvider.ts: kept main's displaySettings import and its
three new fields in the state posted to the webview, read from this unit merged
overlay copy so a pinned view posts its own values, and kept this unit validated
setValues while routing its payload through withoutInvalidDisplaySettings so an
invalid display value is dropped and logged before anything is stored, as main
does.
- src/extension/api.ts: kept main SettingsWriteError doc block and its
invalid-display-value filtering, and kept this unit snapshot-then-write,
restore-in-the-same-catch, rethrow-the-original transaction beneath it.
- src/extension/__tests__/api-configuration.spec.ts: kept main new
display-settings tests unchanged in intent, extending their doubles with the
reads this unit performs before its first write and pointing two assertions at
the writes that actually follow the settings here (the mode fan-out and the
webview post) plus the rollback of the record the save already made.
Verified: tsc clean; eslint --max-warnings=0 clean package-wide with no new
suppressions; prettier --check clean; 932 tests across the affected suites green
(api-configuration, displaySettings, ContextProxy, ClineProvider,
webviewMessageHandler, parallelMode, apiHandlerRebuild, registerCommands,
ProviderSettingsManager).
The fail-closed getProfile read still has no test.
setConfiguration reads the existing record before any write when hasConfig resolves true (src/extension/api.ts Lines 670-673). If that read rejects, the call must abort before it mutates anything. None of the eight tests makes that initial read reject. Every hasConfig: true fixture resolves getProfile. This test file therefore does not catch two regressions:
A change that moves the read after saveConfig.
A change that swallows the read error.
Add a case with these mocks:
hasConfig resolves true.
The first getProfile call rejects.
Then assert these results:
setConfiguration rejects with the same error.
saveConfig, setValues, deleteConfig, setProviderSettings and setModeConfig are not called.
As per path instructions: "For guards and validators, require tests for both the accept path and the reject path through every public entry point."

Failed pre-merge checks:
- Regression Evidence:
Add three focused `vscode.spec.ts` tests: set `globalThis.localStorage` to
`undefined`; provide a storage object without `getItem`; and return malformed
JSON from `getItem()`. In each test, assert `getState()` does not throw,
repeated `getViewStateId()` calls return the same generated ID, and the
in-memory fallback remains authoritative.
- Security Boundaries:
Bind each persisted view-state ID to the exact host-created `WebviewPanel` or
`WebviewView`, and require that binding during `webviewDidLaunch`. Preserve or
re-authenticate ownership after disposal and extension-host reload. Do not load
or post a profile for a disposed or unowned ID. Redact API keys, tokens, OAuth
credentials, AWS credentials, and every other secret provider field before
returning `apiConfiguration` to a webview. Add a regression test that submits a
disposed or unowned ID and verifies that the profile is neither loaded nor
posted.
- Lifecycle Resource Cleanup:
Close or invalidate `providerProfileMutationQueue` at the start of `dispose()`.
Reject queued callers without invoking their callbacks. Abort the active
mutation, or await it with disposal-aware rollback. Check `_disposed` before
each queued callback and before every post-disposal task, profile, shared-state,
and view-state write. Add a regression test that blocks one mode/profile
mutation, queues a second, disposes the provider, releases the first, and
verifies that the second performs no writes.

- Persistence Integrity:
Wrap the complete `persistProviderProfile` save and activation sequence in a
transaction-style compensation path. Snapshot the prior profile record,
metadata, active selection, mode mapping, shared provider settings, and affected
view-state entries before `saveConfig`. If any activation or refresh write
fails, await all in-flight writes, restore or delete the profile, restore every
changed store and view-state entry through their serialized queues, and report
compensation failures explicitly. Do not return `undefined` while the new
profile remains persisted.
- Lifecycle Resource Cleanup:
Invalidate and close `providerProfileMutationQueue` at the start of `dispose()`.
Reject queued callers without invoking their callbacks. Abort the active
mutation, or await it with disposal-aware rollback. Check `_disposed` before
each queued callback and before every task, profile, shared-state, and

2759-2771: The sign-out suite still does not restore the provider members it replaces.
The earlier finding still applies. The sign-out tests assign contextProxy, providerSettingsManager, and upsertProviderProfile on the module-level mockClineProvider. The suite's beforeEach only calls vi.clearAllMocks(). The rename suite (Lines 3016-3024) and the launch suite (Lines 958-969) both snapshot and restore the members they replace. The sign-out suite has no matching teardown.
…ites and retake the deleted cases
Resolves the five open CodeRabbit threads on Zoo-Code-Org#1560 at 8cc8f33. Four are teardown in the specs
this unit added; one is a behaviour change confined to the public API round trip.
- extension/api.ts: setConfiguration drops viewStates from the settings payload before the forward
write, and from the snapshot the rollback replays. The map is a snapshot of every view's
selection: writing a caller's copy forward pins views this call does not own, and replaying
the getter's copy on failure rolls them back to where this call found them. Both consult
isNonPortableSettingsKey, the list the export schema above and the import path already use,
which Zoo-Code-Org#2226 adds at its head (e9d0a2a) for the read side of the same round trip - that PR
filters what an external caller may read, this one filters what it may write. getConfiguration
and ContextProxy.getValues keep the key: the host's own consumers still need viewStates.
- core/config/ContextProxy.ts: declares NON_PORTABLE_SETTINGS_KEYS and exports
isNonPortableSettingsKey beside the export schema, so the two PRs share one rule instead of
each keeping its own copy of the key list.
- ClineProvider.spec: the mode-switch timeout test brackets its flow in try/finally so a failed
assertion cannot leave the gate unresolved, the prototype spy installed, or the timers faked
for the rest of the file.
- webviewMessageHandler.spec: the sign-out suite restores the three fixture members its tests
reassign. Measured control: with the assignments unrestored the file is still 176/176, so the
leak is latent rather than failing - vi.clearAllMocks undoes call history, never a property
assignment, and mockClineProvider.contextProxy alone is read 28 times by the eight describes
that follow.
- ClineProvider.sticky-mode.spec: the three temporary-id providers are disposed in finally, and
the third restores mockContext.globalState.update there before disposing, so a failing
assertion cannot leave the rejecting mock installed for the teardown below it.
- webview-ui ExtensionStateContext.spec.tsx: restored the 13 cache-interning and task-identity
cases main carries (from upstream c4ed96c, Zoo-Code-Org#2217) with the expectMessages, InternSpy and
cacheFor scaffolding they need and main's afterEach(vi.restoreAllMocks). They came back with
the merge of main; our scaffolding cleanup (fda1600) removed them without moving them
anywhere, and webview-ui/src/utils/__tests__/stringCache.spec.ts covers the class, not this
provider wiring.
Verified: src tsc --noEmit exit 0; webview-ui tsc --noEmit exit 0; eslint --max-warnings=0 clean
on every touched file with src/eslint-suppressions.json byte-for-byte unchanged; prettier clean.
856 tests green across api-configuration (17), api-set-configuration (1), ContextProxy (64),
ClineProvider (448), sticky-mode (46), sticky-profile (23), apiHandlerRebuild (40),
parallelMode (41) and webviewMessageHandler (176); webview-ui ExtensionStateContext 43/43.
Test (negative control for the API filter): with neither filter in place the new case fails with
`expected { Object (currentApiConfigName, modeApiConfigs, ...) } to not have property
"viewStates"` while the other 16 cases in the file pass.

Major · After compensation, the deleting view shows the replacement's name… · ClineProvider.ts:3903-3914
src/core/webview/ClineProvider.ts:3903-3914 Major · Data Integrity & Integration · Heavy lift
After compensation, the deleting view shows the replacement's name but runs the deleted profile's settings.
The new throw sends deletion into the deleteProviderProfile compensation block after activateProviderProfile({ name: profileToActivate }) has already committed on the viewPinsDeletedProfile path. That activation set this view's viewLocalState.currentApiConfigName to the replacement and cleared its apiConfiguration overlay. The compensation then restores:
the shared selection, through contextProxy.setValue.
the shared provider settings, through setProviderSettings(previousSharedSettings).
the durable viewStates pin.
The compensation does not restore this view's in-memory buffer. As a result, getState() returns currentApiConfigName: <replacement> with apiConfiguration taken from the shared store. The shared store now holds the deleted profile's settings again. New tasks from this view record the replacement name but send the deleted profile's provider, model, and credentials. The in-memory pin also differs from the durable pin, which the merge put back on the deleted profile.
Any failure after activation reaches this state. Examples are this new throw and a rejected postStateToWebview. The new test in ClineProvider.parallelMode.spec.ts at Lines 1793-1800 records this split and accepts it: "the live overlay of the view that ran the activation keeps the replacement".
Before the delete commits, snapshot this.viewLocalState.currentApiConfigName and this.viewLocalState.apiConfiguration. In the catch block, restore both through _saveViewLocalStateFromMutation, in a step that runs independently of the other restores. Then rebuild the current task handler with updateTaskApiHandlerIfNeeded(previousSharedSettings, { forceRebuild: true }). Add an assertion that getState() pairs the restored name with matching settings after a failed deletion.

…ed activation write
activateProviderProfileUnlocked clears this view's apiConfiguration overlay in the same
Promise.all as the shared settings write, so a partial failure left the view holding the
activated profile's pin with no overlay at all: getState() then paired the new name with
whatever the shared store held, out of step with the handler the failure path had just
force-rebuilt.
The legs are not atomic with each other, so the failure path now decides after every leg
has settled - allSettled rather than all, matching upsertProviderProfile - and puts the
overlay in the state that agrees with the pin this view actually holds: the activated
settings when the pin write took the new name, which is the invariant
refreshViewLocalStateForUpdatedProfile enforces on the success path and the configuration
the rebuild handed the task, and otherwise the overlay captured before the switch.
Covered on both rejecting legs: the provider-settings leg, where both existing cases now
assert the reported name against the reported settings, and the pin leg, added as its own
case. Without the restore the three assertions fail (38/41); with it 41/41, and the
ClineProvider, sticky-profile, sticky-mode, parallelMode, webviewMessageHandler,
api-configuration, ContextProxy and registerCommands suites pass unchanged.

The comment's central failure path is refuted. Line 1793 clears the tracked tab ref only when that ref is the disposing view, so closing a non-tracked tab does not clear the ref of a live tab. The proposed assignment concern is not supported by the inspected creation path, so no fix is warranted.
259-314: Add the fail-closed test for a profile read that rejects.
An earlier review asked for this case. It is still missing: no test sets hasConfig to true and makes the initial getProfile reject. setConfiguration reads the existing record before it writes anything (src/extension/api.ts Lines 680-682). A regression that moves that read after saveConfig, or that swallows its error, would pass the current suite.
Add a test with hasConfig: vi.fn().mockResolvedValue(true) and getProfile: vi.fn().mockRejectedValue(new Error("read failed")). Assert that:
setConfiguration rejects with "read failed".
saveConfig, setValues, deleteConfig, setProviderSettings and setModeConfig are not called.

…filter
The import path hard-coded the key name while the export schema, both API settings
writes and this branch's own api.ts comments all consult NON_PORTABLE_SETTINGS_KEYS
through isNonPortableSettingsKey. The list has exactly one entry today, so the two
spellings select the same key: importExport.spec.ts is 55 green before and after and
the paired webviewMessageHandler.spec.ts is 176 both ways (231 combined before,
231 after). What changes is drift - a key added to the list later would keep being
exported, keep being blocked on the API writes, and get silently imported here.
webviewMessageHandler.spec.ts: the comment above the "re-pins only the view" case said
the pin goes to "the first available profile" while the assertion two lines below, and
the next case - "re-pins the view to the shared global profile rather than the first
listed profile" - pin the shared global selection. Comment only; behaviour and counts
are unchanged.

getViewStateId() reused any stored string that survived normalization, so a persisted id
longer than 64 characters came back on every launch while the extension refused to store
it: the "Ignoring an oversized viewStateId" log (ClineProvider.ts:945-947) meant this view
stayed on its pre-launch temporary id forever, which is the stranded state the reuse path
exists to avoid. The wrapper now declares MAX_VIEW_STATE_ID_LENGTH = 64 - the host keeps
its own copy private and the webview cannot import it - and refuses an id above it, while
still reusing the largest legal id rather than minting a new one away from real per-view
state.
The comment also claimed the host rejects every Object.prototype member name. It does not:
setViewStateId refuses only "__proto__" by name (ClineProvider.ts:938). The webview still
refuses every prototype member, deliberately stricter than the host rather than a mirror:
those names are useless keys on this side, because writing them into the state object goes
through the prototype setter and the later spread drops them. The length cap is the part
that mirrors the host, and the comment now says which is which. The same overstated claim
in the prototype-member case comment was corrected too.
Test first: both cases were written against the constant before the cap existed, and the
oversize case failed exactly as expected - 1 failed / 17 passed, returning the stored
65-character id. Control with only the length disjunct removed: 1 failed / 17 passed,
failing only "generates and persists a fresh id when the stored id is longer than the host
limit". vscode.spec.ts is 16 passed before this commit and 18 after. The whole webview-ui
suite is green: 188 files / 2508 tests. tsc clean (root typescript against the webview-ui
project), eslint clean on both files, prettier clean; src/ is untouched here so
src/eslint-suppressions.json is unchanged.

The rename path keeps the profile id unchanged, so the id in renamedSettings matches the id the profile already has. The inspected code shows no failure that an extra id key in a view overlay would cause. Stripping id would only match the persistence path's shape.

## ESLint Suppressions
When writing new code:
- Avoid floating promises; add `void`, `await`, or `.catch()` as appropriate.
handleModeSwitch uses runToCompletion: true, so a timeout rejects the caller without aborting the mutation. The tool handles that rejection instead of reporting success. Both mode validations use the same customModesManager.getCustomModes() source, and the tool rejects an unknown mode before the provider call.
…settings write
Two review rows on this branch:
- webviewMessageHandler.ts: the updateSettings loop wrote every key the payload carried
through provider.setValue, so a renderer that included viewStates would overwrite every
view persisted mode and pin in one shot and bypass the ownership checks in setViewStateId.
The import path and both API writes already refuse that key through isNonPortableSettingsKey;
this write path now follows the same rule.
- TranslationContext.locale-loading.spec.tsx: the new cases awaited loadLanguage themselves,
which supplies the bundle even to a provider that deferred the load or switched language
later. They now capture the provider own call (spying the module export and recording the
promise it returns) and await that, so the assertion depends on the provider starting the
load rather than on the test starting it.
Measured first: the viewStates case fails at 06aab59 with "expected the mock to not be
called with arguments: [ viewStates, Anything ]". With the provider effect changed so it no
longer calls loadLanguage, the locale case fails on its recorded-call assertion with
"expected 0 to be greater than 0", which the old form would have passed.
webviewMessageHandler.spec.ts 177 passed, TranslationContext.locale-loading.spec.tsx 6
passed, src tsc 0 errors, eslint 0 problems, webview-ui tsc clean, prettier clean, no

Check the buffer again after the second profile lookup. The current code drops mutations that land during that wait.
postLoadBuffer is this.viewLocalState itself, not a copy. mergedState is built from it before the re-resolve await. During that await, activateProviderProfile can run on this view. Its setValue("currentApiConfigName", "cfg-c") and overlay clear write into this.viewLocalState through _updateViewLocalStateFromMutation. Line 1117 then replaces the buffer with mergedState, which still holds cfg-b and the cfg-b settings.
Consequence: the durable pin and shared store say cfg-c, but this view's in-memory buffer says cfg-b. getState() and createTask use cfg-b until the next mutation. Before this change, only the first lookup had this lost-update window. The re-resolve adds a second window.
Capture the buffer fields before the second await. After the await, reapply any field that changed. If the name changed again, drop the re-resolved settings.

src/core/webview/ClineProvider.ts:3563-3592 Minor · Data Integrity & Integration · Quick win
Put the selection restore and the mode-mapping restore in separate try blocks.
One try block wraps activateProfile for the selection and the setModeConfig loop. activateProfile({ name: previousManagerGate.currentApiConfigName }) calls getProfile first, so it throws when the selected record is missing. One trigger: the record restore at Line 3535 failed and the previous selection was the deleted profile. In that case, the mode loop never runs. Mappings moved onto the replacement ID stay moved, even though they could be restored on their own.
The surrounding compensation says that each restore is independent and logged. These two legs write different fields and need separate isolation.

saveSpy replaces ClineProvider.prototype._saveViewLocalStateFromMutation for every instance. The cleanup runs only after both assertions pass. If an assertion fails, the spy stays installed. Every later test in the file then throws "view write down" from each view-local write. The neighboring timeout test at Lines 5459-5484 was fixed for the same failure-path leak.

The activation writes the replacement into this view's buffer through setValue("currentApiConfigName", ...) and persists it to the view's viewStates entry. It clears viewLocalState.apiConfiguration. It also rebuilds the current task's handler with the replacement's settings.
A later step throws. Two triggers are now reachable:
the new fail-closed throw in rePinViewLocalStateForDeletedProfile (Lines 3925-3936);
a failed postStateToWebview.
The catch restores the record, the list, the manager gate, the shared selection, and setProviderSettings(previousSharedSettings).
The catch does not restore this.viewLocalState.
Result: viewLocalState.currentApiConfigName still names the replacement. The overlay is undefined, so getState() serves the restored shared settings, which belong to the deleted profile. The webview shows one profile, and new tasks use the deleted profile's provider, model, and credentials. The current task keeps the replacement's handler while the shared store is back on the deleted profile.
The pin restore has a second gap. The viewStates merge (Lines 3607-3624) rewrites only entries that named the deleted profile before the delete. Suppose the view had no pin. Its new durable entry for the replacement then survives the rollback.
ClineProvider.parallelMode.spec.ts "keeps the other restores running when the manager gate cannot be read back" accepts this split: its comment says the live overlay "keeps the replacement it activated into."
Fix:
Before the try, capture this view's pin and overlay.
In the catch, restore both before the viewStates merge.
In the catch, rebuild the current task's handler with the restored effective settings.
try {
await this.contextProxy.setProviderSettings(previousSharedSettings)
} catch (restoreError) {
...
}
+ try {+ // The activation branch moved this view's pin and cleared its overlay. Put both back+ // so the name and the settings served by getState() describe the same profile.+ await this._saveViewLocalStateFromMutation({+ currentApiConfigName: previousViewPin,+ apiConfiguration: previousViewOverlay,+ })+ this.updateTaskApiHandlerIfNeeded(previousViewOverlay ?? previousSharedSettings, { forceRebuild: true })+ } catch (restoreError) {+ this.log(+ `[deleteProviderProfile] failed to restore this view's pin: ${restoreError instanceof Error ? restoreError.message : String(restoreError)}`,+ )+ }

`WebviewView`, and require that binding during `webviewDidLaunch`. Reject
disposed, unowned, or mismatched IDs before `loadViewState()` and before posting
state. Redact API keys, tokens, OAuth credentials, AWS credentials, and all
other secret provider fields from `apiConfiguration` sent to the webview. Add a
regression test that submits a disposed or unowned ID and verifies that the
profile is neither loaded nor posted.
- Persistence Integrity:
Make `persistProviderProfile` transactional for both activation modes. Snapshot
the prior manager record, profile metadata, selection, mode mapping, shared
provider settings, affected view-state entries, and task/view-local state before
`saveConfig`. Await all writes and post-save refreshes. After any failure,
compensate every write that landed through its serialized store, await each
compensation, and report compensation failures. Do not return `undefined` while
the new profile or partial activation state remains persisted.
- Lifecycle Resource Cleanup:
Make provider disposal close `providerProfileMutationQueue`, reject queued
callers without running their callbacks, and abort or await the active mutation
with disposal-aware rollback. Check `_disposed` before queued callbacks and
before each task, profile, shared-state, and view-state write after an await.
Add a regression test that blocks one mode/profile mutation, queues a second,
disposes the provider, releases the first, and verifies that the second performs
no writes.

## ESLint Suppressions
### Typed test files
New or substantially changed test files must not add `typescript-eslint/no-explicit-any` suppression entries to `src/eslint-suppressions.json`:
- Access private members with bracket notation (`provider["view"]`) and call public members without casts so their generic signatures keep checking arguments.

Draft PR — vps2 unit F3 (mode/profile writes).
Tracking: fork issue 41 (vps2 series ledger). Upstream issue: #1559 (this series' gap record; the original upstream bug is #978). Port source: the F1c-head-to-CS residual, cross-checked against upstream PR #979 (fix(webview): isolate parallel mode and provider profile writes) — closed/superseded by the vps2 series; the fork issue 41 ledger names #979 as the F3 port source.
What this unit does at head ca61d20
Budget
Unit delta vs the stack base: 10 files, +919/-65 (a+d 984 vs the 400-soft / 1000-hard budget: soft-over, hard-under; the unit carries the production isolation logic). The PR diff vs upstream/main is 33 files (+9186/-511) because the branch is stacked on the unmerged F1-F2 series; the series merges bottom-up, at which point each PR's CI gate measures its own unit. The CI mutation-diff changed-line advisory is a by-construction artifact of the stacked diff.

Series mechanics
Pre-merge ERROR-row pre-check (head 9c2bee3)
setViewStateIdnow 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)._saveViewLocalStateFromMutationpersists 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.--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.upsertProviderProfilewithactivate=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 throughupsertProviderProfileso 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 onlyapiProviderfalling back to shared state.--max-warnings=0clean, 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
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
--max-warnings=0clean; 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 a5a2f60)
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=0clean; 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 b68744c)
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
updatedAtreddens exactly the prune test, aloadViewStatethat adopts the unowned temporary-id entry reddens exactly the stale-entry test, restores byte-exact (hash match); eslint--max-warnings=0clean (src and types); prettier merge-ref gate ALL-MATCHED.Follow-up: review-round fixes from the series (head 390c0d4)
A review round on this unit produced three fixes. When the view's durable mode pin write rejected inside the mode-switch handler, the task-history write and the in-memory task mode had already landed and the caller delivered the submitted message with the new task mode against the view's unchanged mode and mode-linked API configuration - the failure now restores the pre-switch task mode and history entry before rethrowing (new sticky-mode test; negative control: dropping the rollback reddens exactly that test).
The fallback deletion path's re-check of whether this view pinned the deleted profile was unreachable (a view pinned to the deleted profile takes the activation path above and returns); the dead branches are removed, behavior-preserving (spec green).
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=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED. The rebuild's negative control (dropping it reddens exactly the sibling re-pin test, byte-exact restore) runs in the units that own that test.Proofs: ClineProvider.spec 293/293, sticky-mode 34/34 (new pin-write-failure rollback test), parallel-mode 34/34 (sibling re-pin test asserts the task handler rebuild and sticky-name re-point); negative controls: dropping the rollback call reddens exactly the rollback test, dropping the rebuild reddens exactly the re-pin test, restores byte-exact (hash match); eslint
--max-warnings=0clean; tsc clean except the two known local telemetry-dist noise lines; prettier merge-ref gate ALL-MATCHED.Updated this round (CodeRabbit follow-up, head 08c6fcb)
handleModeSwitchUnlockedreconciles every write it owns (shared mode, durable view pin, task mode, task history) when a failure lands after the task-mode write - including the mode-linked profile activation - sosubmitUserMessagedelivers the submitted message on the pre-switch mode and profile instead of a half-applied switch; regression test included.taskApiConfigName); regression tests cover both sites.afterEachdisposes the per-test provider before resetting the instance registry; the webview state-payload test renamed to describe what it asserts.Updated this round (CodeRabbit follow-up 2, head c820dd0)
taskApiConfigName === deleted profile(the view-buffer re-pin stays unconditional), so a pinned view whose task follows another sticky profile keeps its conversation's settings and persisted profile name. Regression test included (negative control: removing the guard reddens exactly that test); the existing sibling re-pin test's task double now names the deleted profile as its sticky profile, matching what the test asserts.Updated this round (CodeRabbit follow-up 3, head 0b08bb0)

Stryker suppression comments removed
Per the AGENTS.md policy (never add Stryker directives; remove them when a file is touched), all
// Stryker disabledirectives were dropped from this PR. Equivalence rationale for the removed suppressions:CR round 2026-10-15 (b)
SwitchModeToolnow reports an error result (and records the failure) when the provider reference is released before the switch executes, instead of a false success; the released-provider test asserts the error result.setValuesnow validatesmodeagainst custom modes carried in the same payload (createTask/setConfiguration register them only after the call), so a brand-new custom mode in the payload is no longer dropped. Regression test added; the identical block in the sibling units received the same fix.CR round 2026-10-15 (e)

Row-9 update (head d3ef740)
upsertProviderProfilereads the saved profile back aftersaveConfigand feeds the normalized record to every post-save consumer (CR Security Boundaries).viewStateswriters restore the cache to the durable value when the write rejects, before rethrowing (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.
Upstream refresh (head d3ef740)
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 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.
