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cross-checked against upstream PR #979 (fix(webview): isolate parallel mode and provider profile writes) — closed/superseded by the vps2 series; the fork issue 41 ledger names #979 as the F3 port source.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.

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).
…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.

Source excerpt: **Patch Gate (`target: 70%`)**: New or modified lines in PRs touching `webview-ui/src/` must meet minimum test coverage, ensuring state changes and new UI logic stay tested over time.
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
suppression changes.

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.

view-state entries, and task/view-local state before `saveConfig`. Await every

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)}`,+ )+ }

returns undefined for any path carrying an excluded segment. Calling the gate's own exported function printed packageForPath("src/core/webview/__tests__/ClineProvider.spec.ts") -> undefined, and the priced manifest below lists 9 extension files — src/activate/registerCommands.ts, src/core/config/ContextProxy.ts, src/core/config/ProviderSettingsManager.ts, src/core/config/importExport.ts, src/core/task/Task.ts, src/core/tools/SwitchModeTool.ts, src/core/webview/ClineProvider.ts, src/core/webview/webviewMessageHandler.ts, src/extension/api.ts — the spec is not among them and src/core/webview/ClineProvider.ts is.
What the gate actually charges on this PR
Priced by me at the commit CI itself prices, re-run this pass against the tip main actually holds: git merge-tree --write-tree of main tip 332d30fbb9d8852a61b4512a5ce550e10cf84f24 with head 4dcc7ad769120f582a52272aa1b9613ae2264013 (exit 0, 0 conflicted paths), then git commit-tree <tree> -p <tip> -p <head> → twin 5c8e03bd6f3db764fd8ef73b4aeeba9b934c8a1e. The pricing worktree .tmp-cr-audit/s3lane/wt-task100-basecheck was checked out to that twin; git rev-parse HEAD printed 5c8e03bd6f3db764fd8ef73b4aeeba9b934c8a1e and git rev-parse HEAD^{tree} printed 26a5fcc71a92ec453654798fd138518869dab3b4, asserted equal to the merge tree before every run, porcelain 0 — the gate reads file contents from checked-out disk at :302, so the checkout is part of the measurement. Gate blob scripts/stryker-diff.mjs = 7dfe0006d2d5c7e4d2282f65f68b8ed5f16866bc (30,108 B, sha256-16 c332971815aecfaf), read at both tips named below and identical at each; the copy executed was .tmp-cr-audit/s3lane/probe/verbatim-task100.mjs (30,215 B) for the caps-intact refusals and .tmp-cr-audit/s3lane/probe/raised-task100.mjs (30,221 B) for the per-file charges. Run logs: .tmp-cr-audit/s3lane/task103-twins2.json (17,847 B, sha256-16 436a8511f6d78cf5), the same instrument re-run at the previous tip e487cd7b2a497aa1d9b60f9b0cb497f7839bb629 in .tmp-cr-audit/s3lane/task103-twins-old.json, and the per-file charge run .tmp-cr-audit/s3lane/task103-files.json (5,421 B, sha256-16 5cd4d65972460161). Each line below names what the version being replaced carried and what the re-run printed.
unmodified manifest at 332d30fbb9d8…: extension1,707 counted executable lines / 343 selectors over 9 files; 0 advisories; the gate printed merge-base 332d30fbb9d8, which is the twin's first parent. Deciding package: extension. Unchanged from the 1,707 / 343 this body carried — the same instrument at e487cd7b2a49… printed 1,707 / 343 over 9 files, and the caps-intact run refuses at the identical sentence and number at both tips: extension has 1707 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.
charged row for src/core/webview/ClineProvider.ts: 1174 counted executable lines at 332d30fbb9d8…; its diff against that tip on the twin is re-measured here as 2018 added / 251 deleted (git diff --numstat 332d30fbb9d8 5c8e03bd6f3d -- src/core/webview/ClineProvider.ts), matching the 2018 / 251 carried. The gate totals counted executable lines, not added lines, which is why the two figures differ; the charge is unchanged at 1174 from the previous tip. Every priced file and its charge at this tip: src/core/webview/ClineProvider.ts 1174, src/activate/registerCommands.ts 208, src/core/webview/webviewMessageHandler.ts 168, src/extension/api.ts 105, src/core/config/ProviderSettingsManager.ts 26, src/core/task/Task.ts 12, src/core/tools/SwitchModeTool.ts 7, src/core/config/ContextProxy.ts 5, src/core/config/importExport.ts 2.
with src/core/webview/__tests__/ClineProvider.spec.ts named as excluded: identical to the manifest above; nothing maps to it, so the ask I am correcting could not have moved the number.
excluding src/core/webview/ClineProvider.ts brings extension from 1,707 to 533 over 8 files — 33 lines still over — unchanged from the 533 this body carried. The selector count for the excluded manifest (71 in the version being replaced) is not renewed here: my per-file probe prints line charges, not per-file selector counts, so that figure stays as published rather than being re-claimed.
Pricing the same tree against the recorded frozen base e943530c8486 — re-rooted with commit-tree -p <that base> → fc7a4c538a53c33a817064443e8ec4af9829cd60, git rev-parse HEAD printed as fc7a4c538a53c33a817064443e8ec4af9829cd60, HEAD^{tree}26a5fcc71a92ec453654798fd138518869dab3b4 equal to the merge tree, porcelain 0 — reads extension2,578 / 497 selectors over 29 files, printed merge-base e943530c8486. This one moved. The version being replaced carried 2,528 / 475 over 26 files and the same re-rooting at e487cd7b2a49… reproduces exactly 2,528 / 475 / 26, so the +50-line, +22-selector, +3-file difference is main's own extension charge arriving in its three new commits, not a change on this PR. The CI window above did not move; the frozen window did — which is the whole reason the two framings stay in separate rows.
Drift as its own number, in its own row and never added to the CI window: main tip 332d30fbb9d8…'s tree priced alone on e943530c8486 (commit-tree <main tree> -p e943530c8486, worktree .tmp-cr-audit/s3lane/wt-task100-1928, log .tmp-cr-audit/s3lane/task103-drift.json, 4,040 B, sha256-16 593c941fdb510411, git rev-parse HEAD printed beside each row) reads extension864 / 151 selectors over 23 files; the same measurement at e487cd7b2a49… read 814 / 129 selectors over 20 files. The frozen window sits 871 lines above the CI window at the new tip (821 at the previous one). Drift alone is 864 and the framings differ by 7 lines, which lie in files both main and this PR changed; the same gap held at the previous tip.
f0-1528 reached the same package totals, charged rows and exclusion figures independently (.tmp-cr-audit/.tmp-task94-table.md, 20,200 B, sha256-16 13dd2237133a7516, superseding an earlier 17,911 B copy at 84ca3d33c5a6256e). His run priced the twin at e487cd7b2a49…; the CI-window figures above are mine at 332d30fbb9d8…, and they come out the same numbers — which is what a base-relative measurement should do when the base has not moved.
No mutant number for this PR appears in this body, and the reason the version being replaced gave was too strong. This pass does not claim local Stryker is unavailable on this host: my own run at 1928's head on this machine printed Instrumented 6 source file(s) with 277 mutant(s) (Stryker 10.0.0 through .bin/stryker.cmd, log .tmp-cr-audit/s3lane/task100-preflight.txt). Vitest then died inside .stryker-tmp on this host, so mutants for this PR are unmeasured, not absent by nature.
What these widths are relative to, and what mergeable does not say (added in this pass)
Every width in this body is main-relative, and every one of them is a pre-landing figure. It is the charge of the tree git merge-tree produces between this head and the main tip named beside it, priced from that tip. It says nothing about the world after a sibling lands, and for this PR no measured post-sibling figure exists at all, because this PR collides with its siblings and there is no conflict resolution to price. f0-1528's collision pass — comment 6754338284 (2,880 B, sha256-16 601210e554d8ae31, 2026-11-09T23:31:44Z, data file .tmp-cr-audit/.tmp-task98-summary.md, 38,509 B, sha256-16 6daf784c4a75f27e, 395 lines) measured that head-to-head world: 67 unordered pairs among the family heads, 65 conflicted, only 1565 × 1567 and 1913 × 2357 clean in both directions, src/core/webview/ClineProvider.ts conflicted in 49 of the 67. My own run re-prints those totals exactly (.tmp-cr-audit/s3lane/task103-pairwise.json, 21,081 B, sha256-16 1538eb8be2ae707b — all 14 heads re-fetched from refs/pull/N/head and asserted equal to the heads GET /repos/Zoo-Code-Org/Zoo-Code/pulls/N returned at 00:15:08Z, then 75 runs of git merge-tree --write-tree --name-only, zero checkouts, zero gate prices): 67 pairs inside f0-1528's own subset, 65 conflicted, clean 1565 × 1567 and 1913 × 2357, ClineProvider.ts inside 49 conflicts.
This PR against all 13 of its siblings, the pairs his pass never paired (my four against 1913 and 2357) included: 11 of 13 conflict, clean only against 1913, 2357, and src/core/webview/ClineProvider.ts appears in 8 of those conflicts. His wording — that all four of these PRs conflict with all 13 siblings — is looser than his own table, which already prints 1565 × 1567 merging clean; the counts here are the measurement, and where the two differ the counts are what I defend.
mergeable: true with mergeable_state: blocked, read on this PR by GET /repos/Zoo-Code-Org/Zoo-Code/pulls/1560 at 00:15:08Z, is a base-relative statement: it describes a merge against the branch base and never compares two heads. blocked here is the branch ruleset's six required contexts plus a standing human change request, not a conflict. The same read answers true / blocked for all 14 heads in this family, so 14 mergeable badges sit behind those 65 conflicted pairs — and the badge is stale by construction: at the tip named in this body my own merge-tree already conflicts with main for 1410, 1411 and 1412 (exit 1, conflicted path src/core/webview/__tests__/ClineProvider.spec.ts) while all three still report mergeable: true. Nothing in CI blocks on any of it: mutation-diff is not one of the six required contexts, and f0-1528's pass printed zero checkouts, zero gate prices and no merge queue behind it.
Measured intersection with what main added since e487cd7b2a49…: this PR's changed-file set (git diff --name-only e943530c8486..4dcc7ad76912, 36 files) meets those 45 paths on exactly 3 paths: src/package.json, src/core/webview/__tests__/ClineProvider.spec.ts and src/core/webview/__tests__/webviewMessageHandler.spec.ts. The first is the manifest of the package whose charge is at stake here — the deciding package for every figure in this body is extension, 1,707 counted lines. The two specs map to no package and charge 0, which is why main landing its own edits to them did not move this PR's charge. A maintainer answering this ask is also deciding what happens to src/package.json on rebase: one decision, not two.
The ask, corrected: a choice set, not one remedy
An exclusion reaching src/core/webview/ClineProvider.tsand the files holding the residue: src/activate/registerCommands.ts 208, src/core/webview/webviewMessageHandler.ts 168 and src/extension/api.ts 105 — 481 of the residual 533.
Or the measured split at the 400 a+d reviewability line: 39 units over 15,489 a+d over 36 files.
Or an explicit package-level allowance for extension.
Which gate this bears on — read in this sitting, not asserted
GET /repos/Zoo-Code-Org/Zoo-Code/rulesets/15494382 (Protect Main, enforcement active, delivered body 1,776 B) requires exactly six contexts — check-translations, platform-unit-test (ubuntu-latest), platform-unit-test (windows-latest), compile, knip, e2e-mock — and mutation-diff is not among them; neither is the advisory Zoo Code / PR review gate context, whose own workflow states that repository
rules must not require it. On the author side the fork's only ruleset, sync-with-zoo-code (18174963), printed enforcement: disabled with no
required contexts, and GET /repos/Zoo-Code-Org/Zoo-Code/branches/main/protection/required_status_checks answers 404 (Branch not protected). So the width refusal bears on reviewer acceptance at both ends of the fork-to-upstream path and on neither merge machinery. What this PR
needs from a maintainer is a reviewability decision — one of the three above — and a human verdict on the change request standing on it.
Reviewability currency, labelled as such and never mixed with gate charge
22 of this PR's changed files map to no package and charge 0; their would-be counted-executable-line total is 11,809. src/core/webview/__tests__/ClineProvider.spec.ts is 4,266 a+d, of which 4,110 would be counted executable lines if the gate priced it, and src/core/webview/__tests__/ClineProvider.parallelMode.spec.ts adds 2,811 changed lines, 2,716 would-be counted. Those figures are what a narrower diff would buy; they are not gate charge and the 500-line cap does not measure them.
Producing this correction pushed nothing, resolved nothing, requested no reviewer and changed no review verdict: one PATCH of this body, zero pushes, zero thread resolutions, and 1410, 1411 and 1412 are untouched by it. The queue-wide row is #1991 (comment), patched in place in the same pass.
Heads moved since this body was written, and the predecessor it leans on is no longer a live pull request.
The headline paragraphs are headed at ca61d20c8e3aa6bfd827413065df22adb481cf07 ('What this unit does at head ca61d20', 'Verification numbers (head ca61d20)'). That cited head is an ancestor of the current head 4dcc7ad769120f582a52272aa1b9613ae2264013; 83 first-parent commits (223 counting the upstream/main merges) have landed since. The most recent head named anywhere in the body, d3ef7400eff10f36933900694bc05a9ee56085b7 in the row-9 update, is also an ancestor, 37 first-parent commits (146 commits total) behind the current head.
The body's budget line reads 'Unit delta vs the stack base: 10 files, +919/-65 (a+d 984 vs the 400-soft / 1000-hard budget: soft-over, hard-under)'. Measured at this head the priced leg is 36 files, +14,861/-628, so the quoted delta does not describe the diff this PR carries.
The chain line reads 'PR base is main; the branch is stacked on the F2 head'. Measured: the F2 head bff2a5ca8c030872202a74855cd0193237145739 is NOT an ancestor of this head (git merge-base --is-ancestor exit 1; 105 first-parent commits between). The chain is broken, not merely moved: that branch head is the head of two CLOSED, UNMERGED pull requests, 1554 (head e6afc8d) and 1555 (head bff2a5c), so F2 has no live PR, and this branch carries F2's content only up to 3a24b1b0651f2146b7c0257864e469e16f4fb9f9, with 38 commits of F2's head absent from it. The declared order F1c -> F2 -> F3 therefore cannot be advanced as written.
Measured at this head, with both bases named. Against upstream/main 18861b2 the symmetric diff is 225 files, +16,940/-8,547. The merge base of that tip and this head is e943530c848624bd3054c960be1e4fb0b658509a, equal to this PR's recorded base sha, and the delta from that merge base to this head is 36 files, +14,861/-628. The CI-shaped merge tree (git merge-tree --write-tree, exit 0, clean; synthetic merge commit 6207c57d028abb14b58f743ad68075e77d33a5f7 with the tip as first parent) prices the same 36 files, +14,861/-628.
mutation-diff refuses this leg. CI prices the merge ref, not the PR shape: scripts/stryker-diff.mjs lines 284-291 (resolvePullRequestBase) take the merge commit's first parent as the base, and for a GitHub pull_request run that first parent is the main tip. So the leg mutation-diff actually prices is the delta against the tip, not any shorter delta against a predecessor head.
Job 127165332375, completed 2026-11-05T09:38:58Z, prints at 2026-11-05T09:38:56.0676742Z: 'Mutation gate failed: extension has 1707 changed executable lines (limit 500). Split the PR or obtain a maintainer-reviewed narrow exclusion.'
The same pricing reproduced locally against today's tip returns the identical 1707, so the refusal is not an artifact of main having moved since that run.
The body already says 'the stacked CI mutation-diff reports a changed-line cap artifact by construction (inherited shared content)'. That description is right and the number is now 1,707 against a limit of 500, which is a refusal that fails the job, not a warning.

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

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)
createTaskrestores the previous mode selection when custom-mode registration rejects (identical flagged block; regression test added).CR round 2026-10-15 (f)
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.
