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top of the context values in getState() and ports the getState merging + local state isolation spec coverage from the superseded vps2 source.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.
    • Keeps mode, provider-profile selection, and API configuration separate for each view.
    • Restores each view’s saved state across reloads.
    • Reuses an existing editor tab when available and prevents concurrent opening actions from creating duplicates.
  • Bug Fixes
    • Commands target the intended sidebar or editor tab, including when tabs are unavailable or disposed.
    • Machine-specific view selections stay out of settings exports and imports.
    • Improves recovery when provider profiles are missing or deleted, and when mode changes are interrupted.

Walkthrough

The change adds persisted state isolation for webviews, machine-local settings boundaries, and separate command routing for sidebar and tab panels. It also updates mode and profile handling, tab creation and reuse, and related test coverage.

Per-view state and tab support

Layer / File(s) Summary
Persisted view-state and command contracts
packages/types/src/global-settings.ts, packages/types/src/vscode-extension-host.ts, packages/types/src/vscode.ts, packages/types/src/__tests__/index.test.ts
Defines persisted view-state schemas, a webview message field for view identity, tab command IDs, and global-state key coverage.
Provider view-state lifecycle
src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider*.spec.ts, src/core/webview/__tests__/webviewMessageHandler.spec.ts, src/core/config/ProviderSettingsManager.ts, src/core/config/__tests__/ProviderSettingsManager.spec.ts
Assigns view identities, persists bounded per-view state, merges local and shared settings, and handles history restoration, mode changes, and profile updates and deletion. Webview messages do not await renderer acknowledgments. Tests cover state persistence, cancellation, profile handling, and message behavior.
Machine-local settings boundaries
src/core/config/ContextProxy.ts, src/core/config/importExport.ts, src/core/config/__tests__/ContextProxy.spec.ts, src/core/config/__tests__/importExport.spec.ts
Excludes viewStates from settings export and import. Tests verify that ordinary global settings continue to export and import.
Sidebar and tab command routing
src/activate/registerCommands.ts, src/package.json, src/activate/__tests__/registerCommands.spec.ts, src/eslint-suppressions.json
Adds tab-specific commands, tracks sidebar and tab panels independently, routes actions to the associated providers, reuses live tabs, and shares in-flight creation calls. Tests cover routing, focus, errors, visibility, disposal, and creation behavior.

Merge Risk

Merge Risk: 🟡 Moderate · up to 74f99

Two earlier review concerns about per-view state handling remain unconfirmed as fixed. A reset could be undone by a load already in progress, and a retired provider could still be served through a view's saved API configuration. Confirm both are fixed before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to cd903

Per-view selections affect which service receives task data, but a view’s profile label can diverge from its effective connection settings. Resetting settings can also leave other open views holding usable cached credentials. The demonstrated scope is the extension’s local views and configured services, not a new remote or cross-tenant authority boundary.

Retained concerns

  • Medium · security · inferred: A view’s pinned profile identity is not bound to its effective API configuration. Activation and upsert persist the local profile name but clear the API configuration overlay. After another view activates a different profile, the first view still reports its own profile name while new tasks consume the other profile’s shared connection settings. Unlike the base, identity and configuration no longer follow the same shared selection. This can route task data to an unintended configured service. Durable-write failures can additionally leave the old pin alongside newly committed shared settings.
  • Medium · security · inferred: Resetting shared settings invalidates only the initiating view’s local cache. Another live view that hydrated a profile can retain its API configuration, including credentials, after shared state and stored profiles are reset. Because the merged read gives that overlay precedence and task creation consumes it, new tasks in that sibling view can continue using pre-reset credentials. The base lacked this additional cached configuration path; existing running-task credential retention is not attributed to this PR.

Security review details

Security Blast Radius

  • inferred — The supported concerns affect live views sharing an extension settings/profile context and tasks using their configured API services. They can change effective data destinations or retain credentials locally. No new webview-controlled cross-view identity adoption or cross-tenant authority was demonstrated at this head.

Security Findings and Attack Paths

  • inferred — Ordinary profile selection in a sibling view can change the shared API configuration while another view retains a different profile label. Starting a task in that first view consumes the changed configuration. This supports unintended-service exposure, not a demonstrated unauthenticated attacker or verified policy bypass.
  • inferred — A sibling with hydrated credentials can retain them through another view’s global reset and supply them to a subsequently created task. Clearing the shared store is counterevidence against durable secret retention, but does not invalidate that live sibling’s overlay.

Trust Boundaries and Controls

  • observed — Task creation retains organization allow-list validation before constructing a Task owned by the receiving provider. Panel lookup uses the actual VS Code view object. These controls limit the supported concerns but do not establish consistency between a profile label, cached credentials, and effective connection settings.

Resilience and Maintainability Implications

  • observed — Hydration rejects superseded identities and preserves fields changed during asynchronous loading. Failed persistence does not poison the shared write queue, and mode switching attempts shared-state rollback on durable failure. These controls do not reconcile partially committed profile transitions or invalidate sibling caches during reset.

Hardening Proposals

  • proposed — Define one coherent per-view profile/configuration commit and explicit reconciliation after partial failure. Global credential reset should invalidate every live view’s configuration cache before new tasks can consume it.
  • proposed — Before wiring stable webview identity adoption, bind identity to the owning view and require collision-free identifiers rather than treating syntax normalization as ownership validation. This is a follow-up design safeguard, not an observed reachable vulnerability in the reviewed head.

Full details: Regression Evidence

Explanation

The new rejected-webview-message logging behavior lacks focused coverage. ClineProvider.postMessageToWebview now catches the asynchronous rejection and logs [postMessageToWebview] dropped message type=... at src/core/webview/ClineProvider.ts:1808-1814. The existing negative-path test at src/core/webview/__tests__/ClineProvider.spec.ts:888-898 only asserts that the method resolves without throwing; it does not wait for the rejection handler or assert the log content. A regression that removes or changes this diagnostic behavior can pass the test.

Resolution

Add a focused unit test for a rejected webview.postMessage that flushes the rejection microtask and asserts the exact postMessageToWebview log, including the message type and error text. Add a non-Error rejection case if the String(error) branch is required.

Full details: Persistence Integrity

Explanation

The changed per-view persistence path has a partial-failure gap. In upsertProviderProfile/activation, Promise.all calls this.setValue("currentApiConfigName", name) (ClineProvider.ts:2305-2317). The new setValue first persists the shared setting, then persists viewStates, and only then updates viewLocalState (3760-3763, 3797-3801). If the viewStates write fails after the shared write succeeds, the operation rejects without restoring either the shared profile selection or the prior per-view entry. The remaining profile writes in the same Promise.all also continue. getState() then overlays the stale local profile selection over the new shared value (3506-3510), and a reload can restore the stale durable pin. The base path only wrote the shared setting, so this inconsistency is introduced by the new durable per-view write.

Resolution

Make profile and mode mutations use a compensating transaction or an explicit reconciliation path. Capture the prior shared value, prior viewLocalState fields, and prior durable viewStates entry. If any write fails, await restoration of the shared value and durable entry, restore the in-memory overlay, and report rollback failure separately. Do not place the new per-view write in an uncoordinated Promise.all with profile-store writes unless all partial outcomes are rolled back or reconciled. Add failure tests for viewStates storage rejection during profile activation and mode switching, including assertions after reload.

Full details: Lifecycle Resource Cleanup

Explanation

The changed provider-profile mutation path can continue and duplicate work after timeout cancellation. enqueueProviderProfileMutation() aborts the signal at the 30-second timeout, but advances providerProfileMutationQueue from callerResult rather than the still-running run (ClineProvider.ts:270-305). activateProviderProfileUnlocked() only checks the signal after activateProfile() (2508-2510). The PR adds awaited local-state writes and refreshes for other live views at 2518-2535, then performs task updates and webview posts at 2538-2558 without another abort check. If cancellation occurs during the new Promise.all or refreshViewLocalStateForUpdatedProfile(), the timed-out operation continues those writes and posts, while a later profile mutation can start because the queue already advanced.

Resolution

Keep the mutation queue occupied until the underlying run settles, even when the caller receives a timeout error. Add abort checks after the new local-state Promise.all, after the affected-view refresh, and before task rebuilds, task-history writes, webview posts, and events. If cancellation occurs after a durable write starts, either complete an explicit rollback or mark that write as committed and prevent all later side effects from the cancelled mutation.

No change is required for getPanel() consumers.

getPanel() is only declared in src/activate/registerCommands.ts. No repository file imports or calls it, so this change does not alter any active-surface consumer.

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).
…nd target tab-instance commands

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

Address CodeRabbit walkthrough findings on the F1a unit:

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

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

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

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

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

Tests: the dangling-mode-mapping resurrection scenario, the already-gone secret, the store-level last-profile refusal, the typed-signal contract in the manager spec, and provider-level not-found/propagation pins.
A failed task-history rollback during an aborted mode switch previously propagated into the outer persistence-error handler and surfaced as the switch's own persistence failure. Guard the rollback with its own try/catch so the rollback error is logged with task context and the cancellation return is preserved (CodeRabbit finding on this PR).
…d switch

The in-flight abort rollback rewrote the whole task-history item with the pre-switch snapshot, clobbering any fields the running task persisted during the pending window (tokens, cost, status, apiConfigName). Re-read the item and restore only the mode this switch changed (CodeRabbit data-integrity finding on this PR).
Rebasing onto main tip merged main's createTabPanelUnlocked body with the PR's
serialized creation. Main no longer resolves CodeIndexManager in this function,
so the leftover line referenced an import the PR never added and the suite
failed with ReferenceError. Removing it restores the PR's own delta: 48
registerCommands tests and 459 F1a tests pass.
…overrides

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

Also pins the full default surface of the merged read path, including the apiConfiguration provider fill-in when provider settings sanitize the raw value away (mutation-diff gate).
Rebuilding the F1b unit as main tip + its own delta cleared the conflict with
main. The patch was authored against an older main, so applying it dropped the
alwaysDenyUnapprovedCommands entry from getState(); restoring it with the shared
default constant keeps the settings round trip complete. 410 tests pass.

… spec

The recorded count was 36 while the file has 26 @typescript-eslint/no-explicit-any
violations, so `eslint . --max-warnings=0` fails with "There are suppressions left that
do not occur anymore" on CI. Counts must never increase; this brings the record back to
the actual count.
The re-key guard in F1a only moves an entry this instance authored, so seeding storage
directly no longer exercises the re-key. Seeding through savePersistedViewState matches how
a pre-launch entry is actually created.

flow and rePinViewLocalStateForDeletedProfile to write the replacement settings

…cannot be resolved

When getProfile() fails for the profile being activated, no replacement settings exist, but
the pin was still re-pointed. This view's nested overlay and every other view pinned to the
deleted profile kept serving the deleted profile's configuration under the new name, so
getState() reported a name whose settings belonged to a deleted profile, including its keys.
The overlay is now cleared in both paths.

Tests: 250 passed in ClineProvider.spec.ts; ESLint clean with --max-warnings=0.
