Part of the vps2 durable per-view state series — tracked in easonLiangWorldedtech#41 (cross-repo: standalone a+d measured against the stack base; the displayed vs-main diff includes F1a #1546 until it merges).

Issue (created at PR-open time): #1549

What

Fix unit F1b (2/3 of the F1 split). F1a landed the per-view identity, the durable viewStates pipeline, and the in-memory viewLocalState buffer, but getState() still read every field straight from the shared ContextProxy — so a webview reporting state ignored its own hydrated per-view selections. This PR merges viewLocalState on top of the context values in getState() and ports the getState merging + local state isolation spec coverage from the superseded vps2 source. It also pins the full default surface of the merged read path (mutation-diff gate). The webview-side identity / launch wiring (F1c) lands in the follow-up.

Design decisions

  • getState() builds mergedStateValues = { ...contextProxy.getValues(), ...viewLocalState } and serves every per-view-capable field off the merge: a view-local selection always beats the shared global value; unset fields fall back to the shared value with the existing defaults untouched.
  • apiConfiguration is the merged object { ...providerSettings, ...mergedStateValues.apiConfiguration } — the flat provider-settings mutation path (F1a) keeps repopulating the buffer field, so the re-merge at read time stays coherent (parked item 7, documented).
  • mode / modeApiConfigs read from the merge with the existing defaults (?? defaultModeSlug / ?? {}); no new validation at the read path — unknown modes are already dropped at write time by F1a's setValues / setValue validation.
  • The read path stays side-effect free: getState() never writes, so no queue / rekey behavior is introduced here.

Measurements

  • a+d vs stack base F1a head 0a8ffc9e1: 717 (622+/95−) — over the 400 soft budget (spec-heavy unit: 518 of the added lines are the new spec describes); under the 1000 hard cap. Measured git diff --numstat 0a8ffc9e1..HEAD.
  • src executable lines (mutation preflight): ClineProvider.ts 104+/95−, confined to the getState() region — under the 500-line cap; the spec file is test-only.

Gates

  • eslint --prune-suppressions: pass (suppression counts unchanged: ClineProvider.ts no-explicit-any 12; ClineProvider.spec.ts 198; prune-only reindent reverted)
  • check-types: pass
  • prettier: both files stable
  • vitest: ClineProvider.spec.ts 206 pass (185 pre-existing + 17 ported + 4 new default-value tests)
  • stryker-diff ci @ 0a8ffc9: pass — 127/127 mutants killed (0 Survived, 0 NoCoverage; under the 400-mutant and 500-executable-line caps)
  • e2e / i18n / visual: n/a (zero new i18n strings; no webview-ui changes)

Parked / documented

From the gap-review parked-items register (F1b scope, all bounded):

  1. Flat-mutation apiConfiguration replace (item 7) — a flat setValues provider-settings write replaces the buffer apiConfiguration object; coherent via the getState() re-merge introduced here.
  2. Editor-tab viewStates orphan after window reload (item 8) — no panel serializer; prune-bounded. No change in this unit.

Porting notes

  • Ported hunk-by-hunk (re-implemented against this base from the fix(webview): add durable per-view state base #977 source of record e9a44b2): ClineProvider.ts h17 (the mergedStateValues merge in getState()) + h18 (the full getState() return block: ~85 field reads switched from stateValues.* to mergedStateValues.*, the apiConfiguration object merge, the mode / modeApiConfigs defaults). The getState() method region verified identical to the source of record line-for-line (198 lines).
  • Spec port: local state isolation describe (2 tests) + getState merging describe (15 tests) from the CS ClineProvider.parallelMode.spec.ts, adapted to this file's fixture: the file-level getModeBySlug mock resolves every slug, so the unknown-mode test narrows the mock per-test (same try/finally pattern as F1a); that test's first assertion targets the empty proxy cache (toBeUndefined()) instead of the CS fixture's seeded global default.
  • Gate-driven addition (not in CS): getState default values describe (4 tests) — the mutation-diff gate requires every changed-code mutant killed, so the merged read path's ~45 default-fallback lines are pinned to their defaults (including the codebaseIndexModels fallback, which is only observable after clearing the value the constructor seeds into the context — with a truthy stored value the ?? and && forms of the line are indistinguishable), plus the apiProvider fill-in is exercised through a non-retired provider and through a value that ContextProxy sanitizes away (the only path where the ternary's retired check is observable in the returned apiConfiguration).
  • CS hunks intentionally NOT ported (register in the tracking issue, observed by this PR as well): all six register entries (kimi-code OAuth try/catch, ApiConfigManager className tweak, visual.tsx deletion + baselines, mojibake comment, unused defaultModeSlug import — lands with F1c/F3, repo-config churn).

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added dedicated Plus, Settings, Marketplace, and History controls for editor tabs.
    • Preserved separate settings, modes, and API configurations for each sidebar or editor tab.
    • Restores each view’s state across reloads and sessions.
    • Reopens an existing editor tab when available instead of creating a duplicate.
    • Improved switching between views and restoring task history.
  • Bug Fixes
    • Commands now target the intended sidebar or editor tab.
    • Improved recovery when tabs are unavailable or disposed.
    • Excluded machine-specific view selections from settings export and import.
    • Improved provider-profile cleanup and prevented duplicate tabs during concurrent opening actions.

Walkthrough

The change adds persisted state isolation for sidebar and tab webviews. It adds provider lookup, independent panel tracking, tab-specific commands, machine-local settings boundaries, non-blocking webview messaging, and expanded lifecycle coverage.

Merge Risk: 🟠 High · up to 17136

Per-view mode and profile state can become stale or inconsistent during timeouts, resets, profile changes, and restoration. This can show the wrong selection or prevent tasks from starting, so the issues should be fixed before merge.

Full details: Persistence Integrity

Explanation

A changed mode/profile persistence path has an unhandled partial-failure case. ClineProvider.setValue() first awaits contextProxy.setValue() and then awaits _saveViewLocalStateFromMutation() (ClineProvider.ts:3556-3559). The latter writes viewStates and updates viewLocalState only after that write succeeds (ClineProvider.ts:3593-3597, 3654-3669). If the second globalState.update("viewStates", ...) fails, the first shared mode or currentApiConfigName write remains committed, the per-view pin remains old, and the local buffer remains old. getState() then serves the stale local value over the newly persisted shared value. handleModeSwitchUnlocked() directly uses this path (ClineProvider.ts:2078-2084), and profile activation uses it inside Promise.all (ClineProvider.ts:2232-2240). ContextProxy.updateGlobalState() also updates its cache before the storage update (ContextProxy.ts:366-373), so a failed view-state write can leave a cache ahead of durable storage. No rollback or explicit reconciliation exists.

Resolution

Make the shared-setting and per-view persistence operation transactional or explicitly compensating. Persist the per-view state and shared state in a controlled sequence with snapshots. If either write fails, restore every already-written durable value and restore both ContextProxy caches and viewLocalState to the prior snapshot, awaiting each rollback and reporting failure. Apply the same policy to setValues() and profile activation/deletion paths that call setValue() inside Promise.all. Do not update any local buffer or cache until all required durable writes succeed.

getState(), rather than only checking provider["viewLocalState"].mode. Remove
the stale comment and preserve the expected "architect" value.

In `@src/core/webview/ClineProvider.ts`:
- Around line 3186-3188: Update upsertProviderProfile,
activateProviderProfileUnlocked, and deleteProviderProfile so provider-profile
mutations also synchronize viewLocalState, routing writes through the provider
wrappers or invoking _saveViewLocalStateFromMutation with the replacement
profile name and settings. Ensure getState reflects profile switches and
deletions for views pinned to a prior profile.

In `@src/package.json`:
- Around line 98-117: Add commandPalette menu contributions for
zoo-code.plusButtonClickedInTab, zoo-code.settingsButtonClickedInTab,
zoo-code.marketplaceButtonClickedInTab, and zoo-code.historyButtonClickedInTab,
each gated by activeWebviewPanelId == zoo-code.TabPanelProvider, so these
tab-only commands are hidden outside the active tab while remaining available
within it.

2304-2304: 🗄️ Data Integrity & Integration

Profile deletion still leaves other live views pinned to the deleted profile.

this.setValue("currentApiConfigName", profileToActivate) updates only the initiating view's viewLocalState and its viewStates entry. Another live ClineProvider keeps the deleted profile name in its own buffer, so its getState() continues to return the deleted profile. This repeats the concern raised in the earlier review on the profile-mutation fan-out.

3707-3711: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Invalidate loadViewState() before reset.

loadViewState() only rejects stale work when viewStateId changes. resetState() keeps the same viewStateId, so an in-flight profile or mode lookup can pass the check at lines 758–760 and assign its pre-reset loadedState after _clearViewLocalState(). Add a load-generation token, increment it before clearing state, and require both the token and viewStateId to match before assigning viewLocalState.

3340-3342: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Apply retired-provider filtering to the view-local configuration. loadViewState() loads the selected profile into mergedStateValues.apiConfiguration, and this spread overwrites the filtered fallback before createTaskWithHistoryItem() passes the configuration to Task. A persisted retired apiProvider can therefore reach task creation and be rejected by provider-handler construction. Filter or clear the view-local configuration before merging it.

Clear the view-local profile name when profile hydration fails.

When ProviderSettingsManager.getProfile() throws for a deleted profile, the catch block leaves currentApiConfigName set while apiConfiguration falls back to shared settings. getStateToPostToWebview() then exposes an invalid profile selection paired with another profile's configuration. Assign the name only after successful hydration, or clear it in the catch block.

Synchronize both fields at the profile mutation boundary

getState() lets viewLocalState.apiConfiguration override shared provider settings. Upsert and activation update only currentApiConfigName locally, while deletion updates the replacement name without loading its settings. A view hydrated with profile A can therefore report profile B while postStateToWebview() and later createTask() use A's configuration. Centralize these mutations so they preserve ContextProxy.setProviderSettings() clearing behavior and update both local fields from the active profile, including the replacement profile during deletion.

viewLocalState assertion.

In `@src/core/webview/ClineProvider.ts`:
- Line 2082: Update handleModeSwitchUnlocked so it checks the mutation signal
immediately before setValue("mode", newMode), preventing timed-out operations
from writing state or emitting ModeChanged. Ensure the shared mode update and
_saveViewLocalStateFromMutation persistence are atomic, or roll back the shared

2237-2237: Propagate provider-profile mutations to viewLocalState.

These changes synchronize only currentApiConfigName. Profile settings still use direct contextProxy.setProviderSettings() writes, and deletion updates only the initiating provider. A view can continue using stale settings after profile activation, update, or deletion. Other live views can remain pinned to a deleted profile. Update or invalidate viewLocalState.apiConfiguration for every affected provider and refresh each affected persisted view entry.

…nd target tab-instance commands

Reapply in-flight view-local fields with Object.is identity so a field cleared during the load window stays cleared; route mode switches through setValue so the in-memory buffer and durable write agree, with rollback on failure; refresh cross-instance view-local state on profile upsert, activate and delete and re-pin the buffer after a delete; point focusInput and active-panel re-registration at the tracked tab provider and panel; log dropped webview postMessage failures with the message type; pin tab-instance, focusInput and active-panel identity in the registerCommands tests and type the mdm double in the provider spec.
…overrides

Fold ClineProvider viewLocalState on top of ContextProxy values in getState() (mode, apiConfiguration, and all per-view fields) so each webview reports its own selections while falling back to shared global state for everything else. Ports the getState-merging and local-state-isolation spec coverage from the superseded vps2 source.

Also pins the full default surface of the merged read path, including the apiConfiguration provider fill-in when provider settings sanitize the raw value away (mutation-diff gate).
…tore

deleteProviderProfile only rewrote the UI-facing listApiConfigMeta and
currentApiConfigName in ContextProxy, leaving the profile's settings in the
ProviderSettingsManager store (context.secrets). Per-mode mappings
(modeApiConfigs) that still pointed at the deleted profile re-activated its
stale settings on the next handleModeSwitch, clobbering the active
configuration: the subtask child profile's gpt-4.1-mini leaked into
ask-mode tasks, breaking downstream e2e suites (60s timeouts on search_files
no-match and terminal reuse after zero-chunk shell race).

Purge the profile from the store on delete so dangling mode mappings can no
longer resolve it: listConfig().find(id) fails and handleModeSwitch continues
with the current configuration. The F3 mode/profile isolation commit further
up the chain introduces the same purge plus per-view pin handling.

Regression test: sticky-profile spec "deleteProviderProfile removes the
stored profile so a dangling mode mapping can no longer re-activate it".
handleModeSwitchUnlocked persisted the switched mode only through the
deprecated updateGlobalState, so the in-memory viewLocalState buffer kept
serving a stale restored mode: getValues() merges viewLocalState on top of
the ContextProxy values and would shadow the fresh switch for consumers.

Route the write through setValue so the buffer and the durable global state
stay in sync, and cover it with a regression test for switching after a
restored view state. Also assert the restored mode in public state, and
harden the import viewStates test with a write-tracking proxy across all
write paths (setValues/setValue/setProviderSettings) for seeded and fresh
machines.
…isolate launch-suite provider doubles

ProviderSettingsManager.deleteConfig now throws ProviderSettingsNotFoundError for a missing config and rethrows it unwrapped, so ClineProvider.deleteProviderProfile branches on the type instead of matching the not-found message text that a profile name could spoof; the sticky-mode handleModeSwitch test additionally pins the durable per-view persisted mode and getValues(); the webviewDidLaunch tests restore the mockClineProvider members they replace after each test so launch stubs cannot leak.

CI status update (2026-09-14)

Merged the latest main (ba46d1f34) to advance the merge-base. The previous mutation-diff failure was base drift, not a defect in this PR: the gate's diff (merge-base → PR merge-ref) included ~a week of main's own changed lines, and main's code is not covered by this PR's tests. Upstream #1610 has also made surviving mutants advisory since.

The diff now contains only this PR's own changes; expecting a green re-run of the mutation gate on the new head.

Correction to the status comment above (2026-09-14)

The re-run on head d2392d09e failed at the executable-line scope step:

Mutation gate failed: extension has 577 changed executable lines (limit 500).

This is a stacked-series effect, not new churn from this merge: this PR sits on top of #1546 (f1a), whose ~900 a+d of changes are included in the diff-vs-main. This PR's own layer is ~240 a+d — well under the cap. Once #1546 lands on main, the delta for this PR drops back under 500 and a simple re-merge/re-run of main will turn the gate green. No code change is expected from this PR.

…apture view pin on delete

Address CodeRabbit walkthrough findings on the F1a unit:

- handleModeSwitchUnlocked now bails before the task-level writes when the abort signal has fired, closing the partial-apply window where a cancelled switch could still rewrite the persisted task mode; the existing pre-write guard still covers in-flight aborts.
- Replace bracket access to sibling-instance private members with a typed pinnedProfileName getter and direct private member access (compile-time safe across instances).
- deleteProviderProfile now captures this view's pin before the currentApiConfigName rewrite so a view pinned to the deleted profile while the global selection points elsewhere is still reconfigured with the surviving profile's settings.

Tests: focusInput asserts the tab panel by identity and that no error was logged on the success path; the stalled getProfile double fails loudly on a second lookup (only one lookup is resolvable).

…l buffer

Flat provider-settings writes now flow through the ContextProxy only; merging them into viewLocalState.apiConfiguration turned them into a per-view override that masked later shared updates from other views (the e2e provider-probe suites: 14 failures). Ported from dfcc3e7 of the f1c-webview-identity unit; adds a regression test pinning the profile-activation -> global-write -> getState ordering and retargets the tests that pinned the removed merge behavior.
…-local profile pins

handleModeSwitchUnlocked: an abort landing while updateTaskHistory is in flight previously left the new mode persisted in task history and assigned to task._taskMode before the pre-write signal check bailed; the landed write is now rolled back to the pre-switch item and the method returns before the TaskModeSwitched emit and the durable mode write. TaskModeSwitched now only fires for a completed transition. deleteProviderProfile: the unconditional setValue('currentApiConfigName', ...) overwrote a view's pin when an unrelated profile was deleted; the pin is now re-pointed only when it names the deleted profile, and a deleted-was-global deletion updates the shared store only. The nested apiConfiguration overlay is replaced with the surviving profile's settings only for a view pinned to the deleted profile.

deleteProviderProfile pruned the UI-facing listApiConfigMeta entry but never removed the profile's settings from the ProviderSettingsManager store (context.secrets), so a later listApiConfigMeta sync could resurrect the deleted profile and a dangling per-mode mapping could re-activate it.

The purge now calls providerSettingsManager.deleteConfig and branches on the typed ProviderSettingsNotFoundError (introduced here alongside) so an already-gone secret is an idempotent success -- the stale list entry is still pruned -- while any other failure (e.g. the store refusing to delete the last remaining configuration) propagates. Matching message text instead would let a profile whose name contains 'not found' swallow an unrelated failure.

Tests: the dangling-mode-mapping resurrection scenario, the already-gone secret, the store-level last-profile refusal, the typed-signal contract in the manager spec, and provider-level not-found/propagation pins.
