fix(activate): target title-bar commands to their click-origin instance - #1528
Part of the vps2 durable per-view state series — tracked in easonLiangWorldedtech#41 (cross-repo: this PR is standalone against upstream/main @ 0d937c0).
All title-bar commands (+ / Settings / History / Marketplace / popout / focus) resolve to a single surface-blind "visible" ClineProvider instance, and setPanel's mutual wipe of the sidebar/tab slots leaves stale references once a tab and the sidebar coexist. This PR makes each title-bar command target the instance its click originated from:
setPanel no longer wipes the other slot (each branch assigns only its own slot); the exported setPanel / getPanel signatures are kept.
The four sidebar title-bar handlers target the click-origin provider that registerCommands was handed.
Four new *InTab command ids (packages/types/src/vscode.ts) rewire the editor/title menu, reusing the existing i18n keys/icons (zero new strings); the tab handlers resolve the owning instance via the new static ClineProvider.getInstanceForView(panel) (identity match over activeInstances) instead of the surface-blind getVisibleInstance.
openClineInNewTab reuses the live tracked tab panel (reveal + didBecomeVisible post) instead of unconditionally creating a new provider + panel.
The focusInput post follows focusPanel's selection: the tab provider when a tab is tracked (resolved via getInstanceForView), the sidebar provider otherwise, and nothing when the tracked tab has no live instance.
Palette visibility is gated per surface under contributes.menus.commandPalette: the *InTab ids show while a tab is active, the sidebar ids in every other case, so a palette invocation always targets the surface the user is on.
Design decisions
D1 (mutual wipe): fixed by the no-wipe setPanel. The sidebar onDidDispose asymmetry (the sidebar slot is never cleared) is pre-existing and retained; with no-wipe a stale slot resolves to a disposed instance via getInstanceForView, and the InTab handlers then no-op safely.
D2 (no tab reuse): fixed by the panel reuse via getInstanceForView.
D3 (surface-blind targeting): the five title-bar commands are contributed to both view/title and editor/title in package.json (verified by the Phase-0 A6 audit); the editor/title entries are rewired to the *InTab ids.
D4 (focusPanel tab-first resolution): self-resolves once the no-wipe lands — focusPanel.ts is deliberately unchanged (no spec exists for it).
zoo-code.newTask (command-palette only) intentionally stays on the visible-provider path (focus-sidebar fallback); documented as a known limitation below.
Webview-originated actions are per-instance by construction (setWebviewMessageListener wires this); the single leak (focusPanelRequest) is out of scope here.
Measurements
a+d vs upstream/main @ 0d937c0: 484 (411+/73−) — over the 400 soft budget by 112: the mutation gate required per-post distinct-error catch pinning, an awaited InTab no-op matrix (all four commands), and real-class getInstanceForView coverage (registerCommands.spec auto-mocks ClineProvider, so the real find callback had no coverage). Under the 600 hard cap. Composition: ~372 first-cut (impl + spec) + ~112 mutation-killing tests.
e2e / i18n / visual: n/a (zero new i18n strings; no webview-ui changes)
Parked / documented
zoo-code.newTask stays on the visible-provider path (palette-only surface; focus-sidebar fallback).
The A6 audit's alternate minimal-fix design (public renderContext / getSurfaceProviderOrLog / active-surface-first getVisibleInstance) was considered and not adopted.
Porting notes
None — new fix (F0) identified by the Phase-0 A6 button-targeting audit; no hunks ported from the closed draft PRs.
Updated this round
Pushed bc39e81a5 -> 08225f581 for the two reviewer threads (both replied and resolved):
The commandPalette contribution was at contributes level, where VS Code does not read palette visibility - the when clauses were inert. It now lives under contributes.menus.commandPalette, and the four sidebar commands got complementary when clauses (activeWebviewPanelId != zoo-code.TabPanelProvider). This also closes the palette-with-only-a-tab-open case where the sidebar handler evicted the hidden sidebar's task while the tab did nothing: with a tab active the palette now offers the *InTab variant.
Regression Evidence row: added the focused negative test - both panels tracked, getInstanceForView(tabPanel) returns undefined, the lookup is made and neither provider receives focusInput. Negative control: a sidebar fallback on the failed lookup reddens exactly this test; restore byte-exact (git hash-object verified).
Proofs at this head: registerCommands.spec 52 passed (was 51); eslint (CI command, full src) exit 0; package.json parses; diff touches only src/package.json and the spec.
Format gate follow-up: pushed 08225f581 -> 6a7ae11f6 - the compile job's format:check step (prettier --check . at the repo root, added on main after this branch's base) flagged src/package.json and the spec; both are now prettier-clean at the repo config (part of the spec's formatting drift predates this PR and is normalized by the gate). No behavior change: spec still 52 passed, eslint (CI command) exit 0.
Added editor-tab actions for starting a task, opening settings, browsing the marketplace, and viewing history.
Command palette actions adapt to whether the sidebar or editor tab is active.
Improvements
Opening the task tab brings an existing live tab into view instead of creating a duplicate.
Sidebar and editor-tab actions target the appropriate surface, and input focus follows the active surface.
Bug Fixes
Closing or replacing a sidebar no longer affects a separate editor tab.
The change adds tab-specific command IDs and handlers. It tracks sidebar and tab providers separately, routes actions and focus to the selected surface, and reuses tracked tab panels. Concurrent tab opens share an in-flight creation promise.
Changes: Surface command routing
Layer / File(s)
Summary
Command IDs and menu wiring packages/types/src/vscode.ts, src/package.json
Four tab-specific command IDs and contributions were added. Tab editor-title entries and command-palette items use the tab-specific commands.
Provider lookup and surface lifecycle src/activate/registerCommands.ts, src/core/webview/ClineProvider.ts, src/core/webview/__tests__/ClineProvider.spec.ts, src/activate/__tests__/registerCommands.spec.ts
Sidebar and tab references are tracked independently. Provider lookup matches a live provider to its view or panel. Disposal cleans up view-scoped listeners and matching references.
Surface command handlers and focus routing src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts
Sidebar and tab handlers select their respective provider targets. Focus routing, ordered action posting, and handler-specific error logging are covered by tests.
Tab-panel creation and reuse src/activate/registerCommands.ts, src/activate/__tests__/registerCommands.spec.ts
A tracked tab with a live provider is revealed and reused. Otherwise, a panel is created. Concurrent opens share an in-flight promise. Tests cover placement, visibility, disposal, and failures.

Explanation
The title "fix(activate): target title-bar commands to their click-origin instance" matches the main change. The PR routes title-bar commands (+, Settings, History, Marketplace) to the provider instance the click came from. It adds *InTab command IDs, fixes setPanel slot wiping, and adds getInstanceForView in registerCommands.ts and ClineProvider.ts. The title is specific and accurate, though it is slightly long at 71 characters.
Full details: Description check
Explanation
The description follows the repository template in part. It links issue #1529 under a non-template heading, but the template's "Closes: #<number>" line is absent. The Description, Test Procedure, and Pre-Submission Checklist are substantially covered by the What, Measurements, Gates, and Parked sections. The author gives a detailed description of the implementation, design decisions, and test results. Several template items are missing or unclear: the "Closes:" line, a clear Test Procedure with reproducible manual steps, the Documentation Updates choice, the Visual Snapshots and Videos statement, and the Get in Touch Discord username. The description also uses wording that does not follow the Simplified Technical English style the template asks for, with long multi-clause sentences and internal references (D1-D4, A6, Phase-0) that reviewers outside the series may not follow.
Resolution
Optional improvements: add a "Closes: #1529" line in the Related GitHub Issue section, add reproducible manual test steps to Test Procedure, tick the Documentation Updates choice, state the visual and video status, and add the Discord username under Get in Touch. Shorten sentences and define internal labels such as D1-D4 and A6 where they first appear.
Full details: Security Boundaries
Explanation
No changed path was found that leaks secrets or PII, executes unvalidated input, or bypasses approval or allowlist controls. The changes route fixed UI actions to tracked providers. The webview listener retains its view identity check.
Full details: Regression Evidence
Explanation
Two regression coverage gaps remain. The focusInput negative test at src/activate/__tests__/registerCommands.spec.ts:593-612 returns no provider for either view, so it cannot detect fallback to a live sidebar. The disposal tests at src/core/webview/__tests__/ClineProvider.spec.ts:602-727 do not verify that the new callback clears the tracked sidebar or preserves a replacement. The helper test calls clearSidebarPanel directly and does not cover that wiring.
Resolution
Add a focusInput test with both surfaces tracked, a live sidebar provider, and no live tab provider. Assert the focusPanel arguments and that neither provider receives focusInput. Test that disposing the current sidebar clears getPanel() and that disposing a replaced sidebar preserves the replacement.
Full details: Lifecycle Resource Cleanup
Explanation
Overlapping API task starts can share a provider through the new pending creation promise in src/activate/registerCommands.ts:367-381. Each start then calls registerListeners on that provider (src/extension/api.ts:225-230). Each listener attaches a TaskAborted handler, so a later cancellation emits the API event twice (src/extension/api.ts:467-477). The earlier title-bar disposal race also remains, but the equivalent race existed in the base handler.
Resolution
Give independent API task starts independent providers, or prevent duplicate listener registration on a shared provider. Add a concurrent-start cancellation regression test.

…t must pass
The diagnostics handler moved into the command map unchanged, but the test that invoked the
registered handler went away with it, so nothing in this suite proved that the entry hands the
report the extension context, the output channel and the live provider list, or that it works
without a visible instance. The service's own suite builds the report; it cannot see this
registration at all.
Measured controls: replacing ClineProvider.getAllInstances() with an empty list, and dropping
outputChannel from the call, each redden the restored case with "expected \"vi.fn()\" to be called
with arguments: [ { context: { ... }, ... } ]"; byte-identical restore -> green.
…eads
Listeners were tracked twice - once in the flat list and once in a per-surface map - so that a
disposal callback could release only its own view's subscriptions while a replacement kept its
own. Every drain path already handles that without the map: initializeWebviewView disposes the
previous view's subscriptions when a replacement takes the slot, and each disposal callback is
identity-checked, so a replaced view's callback returns before touching the replacement's. The
sidebar path called clearViewScopedDisposables and then clearWebviewResources back to back, which
released the same set twice over.
Removed: the map, trackViewDisposable and clearViewScopedDisposables. Registrations push straight
into webviewDisposables, the sidebar path drains once, and nothing keeps a second copy of a
subscription it can no longer reach.
The new case resolves a sidebar view, fires every onDidDispose subscription the view received the
way VS Code fires them, and asserts that all four registrations it caused - message listener, focus
registration, visibility listener, configuration listener - were in the provider's list, then
disposed, and that the list is empty afterwards. Measured controls: replacing the drain loop with a
bare list reset, and dropping this.clearWebviewResources() from the sidebar branch, each fail with
"post-drain visibility: expected "vi.fn()" to be called at least once"; removing the focus
registration push, and removing the configuration listener push, each fail with "expected [...] to
include { dispose: [Function Mock] }". All four were restored byte-identically to green. The
pre-existing replacement-race case (a replacement resolving before the old view's disposal callback)
stays green, which is what shows the map was load-bearing for nothing.

excluded): 5 mutants, 3 killed, 2 surviving, 0 uncovered - both survivors are the push removals
above, now pinned. tsc --noEmit clean, eslint --max-warnings=0 clean, src/eslint-suppressions.json
untouched, and the six webview/activate suites green (576 tests) before and after.
The case added for the sidebar leaves the tab branch's onDidChangeViewState subscription
unobserved, so dropping the push that records it in the provider's disposable list changes nothing
any test can see: the subscription then leaks on panel close, and no assertion notices. Same shape
as the sidebar registrations that the mutation run already caught.
The panel-shaped case resolves a WebviewPanel stand-in, asserts its view-state subscription lands in
the same list every other registration uses and is not disposed while the panel is live, and asserts
the provider's disposal releases it exactly once and empties the list.
Measured control: replacing the push with a bare reference leaves the subscription untracked and the
case fails with "expected [ { dispose: [Function Mock] }, ...(2) ] to include { dispose: [Function
Mock] }"; restored byte-identically -> green. Unit-shaped mutation run over the three commits on this
branch (base 2860e2b, 7 changed executable lines, test paths excluded): 5 mutants, 5 killed, 0
surviving, 0 uncovered.

Reply to the Lifecycle Resource Cleanup warning at e4b315196
The row is about a different path from the three commits on this branch, so rather than change code I am answering it in writing with the code read.
What the row describes, verified against 2860e2b3b → e4b315196 line by line.plusButtonClickedInTab resolves a provider once (src/activate/registerCommands.ts:168) and then awaits evictCurrentTask() (:175). ClineProvider.dispose() sets _disposed synchronously (src/core/webview/ClineProvider.ts:953) and evicts the current task itself (:968). evictCurrentTask() (:747-757) has no _disposed guard, so a disposal that begins while the handler is mid-await can reach the same task from both sides. The row's mechanism is real.
What my commits did and did not change about teardown. The three commits on this branch (f1105fddd, 5e44ab06d, e4b315196) touch registerCommands.ts not at all, and their changed lines in ClineProvider.ts are 242-245, 1205-1206, 1287, 1318, 1342, 1357 and 2021 — none inside evictCurrentTask() (:747-757), none inside the disposal eviction block (:948-1002), and none in the title-bar handler. Teardown ordering is unchanged everywhere: dispose() still cancels queued permits, then evicts, then drains the task stack; the sidebar disposal branch still runs log → clearSidebarPanel → this.view = undefined → clearWebviewResources() (:1204-1209); a replacement view still drains before it registers. What the commits removed is bookkeeping, not sequencing — the sidebar path no longer disposes the same listener set twice through two containers, and no subscription is kept in a per-surface map that a later owner cannot reach (src/core/webview/ClineProvider.ts:242-245 explains why the single list is sufficient: replacement drains at initializeWebviewView, and every disposal callback is identity-checked).
What already bounds the race today. A title-bar action cannot pick up a provider whose disposal has started: getInstanceForView excludes instances whose disposal has begun (_disposed is set synchronously at :953 before any await), which is pinned by excludes an instance whose disposal has started (src/core/webview/__tests__/ClineProvider.spec.ts:741-752) — the comment there names exactly this failure mode ("a tab command queued inside that window must not be handed this provider: it would re-run task eviction and workspace refresh on top of the disposal already doing them"). The residual window the row is pointing at is narrower: disposal starting between the handler's resolve at :168 and its first await at :175.
Why this is scheduled scope rather than a fourth change here. The row's own resolution asks for more than a guard: serialise tab title-bar actions with provider disposal or cancel them on disposal, have the disposal path own the same lifecycle lock, and make eviction execute at most once. That is a change to the tab task-lifecycle contract, in the same area that #1919 and #1565 carry (this review lists both as related), and it needs the eviction-once invariant to hold for every title-bar action, not just plusButtonClickedInTab. Landing it inside this unit would put a lifecycle-locking decision behind a PR whose scope is command targeting and listener bookkeeping; it belongs with the unit that owns the tab lifecycle lock.
No code change from me for this row, and nothing here required one: all seven required lanes are green at e4b315196, mutation-diff is green with the unit-shaped local run at 5 mutants / 5 killed / 0 surviving / 0 uncovered, and both resolved threads' fixes are covered by their own measured controls.

## ESLint Suppressions
### Typed test files
New or substantially changed test files must not add `typescript-eslint/no-explicit-any` suppression entries to `src/eslint-suppressions.json`:
- Prefer typed structural doubles: type mock context/proxy classes against the real public types they stand in for (e.g. `vscode.ExtensionContext`), and use `unknown` for storage values and mock callback parameters instead of `any`.
- Access private members with bracket notation (`provider["view"]`) and call public members without casts so their generic signatures keep checking arguments.
- When a partial double cannot be assigned to the real type, cast it once at the construction site (`as unknown as T`) with a comment naming the members the double provides; do not repeat `as any` at every use site.
- Validate with `pnpm --dir src run check-types`, the narrowest affected Vitest suite, and `pnpm --dir src exec eslint --prune-suppressions --max-warnings=0 <relative-test-...

…e clobber guard
Row registerCommands.spec.ts:518: the two no-target focusInput cases proved only that no provider received a post, so a build that logs an error instead of posting passed. Both cases now also assert the output channel stayed silent, using not.toHaveBeenCalled() rather than a message match. Control run recorded before this commit: adding one outputChannel.appendLine at the top of the focusInput try block turns that subset from 5 passed into 2 failed, which is the evidence that the new assertions can fail. The probe was reverted, so only the assertions remain.
Row registerCommands.ts:43: the comment claimed the extension host no longer reads getPanel() directly while ClineProvider.ts imports it (line 127) and calls it (line 1200) in the tab-view disposal check. The wording now names that reader. A grep of src at this head shows only those two lines plus the test file.
Row registerCommands.ts:355: the clobber guard on pendingTabPanelCreation is deleted rather than suppressed. The entry guard hands the in-flight promise to every overlapping caller, so between storing the slot and this finally block nothing else can write the slot and the equality check always held. Clearing unconditionally removes the branch, its mutant, and the Stryker directive.
Gates on this worktree head: focusInput subset 5 passed, open-in-editor subset 17 passed, whole registerCommands.spec.ts 62 passed, tsc -p tsconfig.json clean, eslint --prune-suppressions --max-warnings=0 clean on both files with eslint-suppressions.json left untouched, prettier --check clean.
[vps2-f] One commit on vps2/f0-button-targeting for the three live rows: 9ab5356 (pushed, one head, lease read from ls-remote immediately before).
registerCommands.spec.ts: the two no-target focusInput cases now assert the output channel stayed silent, at lines 486 and 523. The control you asked for was run first: inserting one appendLine at the top of the focusInput try block turns the subset from 5 passed into 2 failed, so the assertions can fail. The probe was reverted before the commit.
registerCommands.ts:43: the getPanel doc comment now names the tab-view disposal reader in ClineProvider.ts that the old wording said was gone.
registerCommands.ts:355: the pendingTabPanelCreation clobber guard is deleted along with its Stryker directive, because the entry guard makes the clobber unreachable; the slot is cleared unconditionally.
Local gates on this head: focusInput subset 5 passed, open-in-editor subset 17 passed, whole registerCommands.spec.ts 62 passed, tsc -p tsconfig.json clean, eslint --prune-suppressions --max-warnings=0 clean on both files, prettier --check clean, eslint-suppressions.json unchanged. Nothing pushed to upstream main, and no review request fired from this lane.
All three live rows on this head are answered with measurements and closed: registerCommands.spec.ts:518 got a real negative assertion on the output-channel mock, with a control that turns 5 passed into 2 failed when an appendLine is placed at the top of the focusInput try block; registerCommands.ts:43 was a stale doc comment naming a reader that still exists at ClineProvider.ts:127 and :1200; registerCommands.ts:355 removed an unreachable clobber guard together with its Stryker directive. Every gate on 9ab5356 has now completed green (33 check runs, 0 failures) and the reviewer's own re-run of this head posted no new rows. Please re-review the current head.

CodeRabbit filed src/activate/registerCommands.ts:167 (root comment 4503339692): the
sidebar plusButtonClicked evicts the registered provider's running task even when the
sidebar is hidden, because the commandPalette rows this branch added keep the command
reachable whenever a tab panel is not the active webview panel. Checked against the
tree rather than the finding text: src/package.json gains a menus.commandPalette
section (8 rows) in which zoo-code.plusButtonClicked sits under
"activeWebviewPanelId != zoo-code.TabPanelProvider"; with a text editor focused and the
sidebar collapsed that context key is unset, so the clause passes and the palette runs
the sidebar handler. The rows restrict an already-listed command rather than introduce
it - what changed is that these handlers dropped the guard upstream's copy had: at
merge-base a4f774b plusButtonClicked opened with getVisibleProviderOrLog and returned
when it found no visible instance (registerCommands.ts:90-104), so the same palette
invocation logged and did nothing instead of aborting a task behind an invisible view.
sidebarCommandTarget keeps the click-origin targeting while the registered provider's
own view is visible, which a view/title click always is, and otherwise falls back to
the visible instance - what these handlers did before the click-origin split: act on
whichever surface is on screen, and do nothing when none is. Applied to plusButtonClicked,
the destructive one, and to settingsButtonClicked, historyButtonClicked and
marketplaceButtonClicked, which only post, so the four stay consistent about where a
palette invocation lands. Telemetry still fires only once a target exists.
registerCommands.spec.ts: the registered provider double states the view/title
precondition (isViewVisible: true), and five cases pin the palette origin - plusButton
click targeting the visible provider instead of evicting behind the hidden sidebar,
plusButtonClicked doing nothing when no surface is visible (asserting the log line and
that no plus telemetry fired), and an it.each over the three post-only commands. With
the guard deleted the lane fails exactly those five and passes the other 62; with the
guard in place the lane is 67 tests green. tsc --noEmit 0 errors, eslint
--max-warnings=0 clean on both files, prettier --check clean, and
src/eslint-suppressions.json is untouched, so no count moves.
The pre-commit hook ran lint-staged on this commit (PATH prepended with
C:/Users/eason/AppData/Roaming/npm so the hook resolves pnpm 10.8.1 instead of falling
through to npx). No --no-verify was used.

marketplaceButtonClicked with the sidebar hidden and no visible provider: each
handler must post nothing, record no telemetry, and log the missing-instance
line. This answers the review row at src/activate/registerCommands.ts:223
(thread PRRT_kwDOSK-bwM606cy7) and covers the same branch the mutation advisory
named at src/activate/registerCommands.ts:216 - 2 mutation test gaps with a
NoCoverage BlockStatement-removal example.
Also states what the shared visible-provider double stands for in the sidebar
cases, so the existing assertions that keep a click on the sidebar whenever the
sidebar's own view is visible say so in the fixture as well as in the test name.
Gates: `pnpm --dir src run check-types` 0; `pnpm --dir src run lint` 0 (the
package script, not a per-file call); `prettier --check` reports both touched
files unchanged; `eslint --prune-suppressions` on the touched spec 0 and
eslint-suppressions.json is unmodified. registerCommands.spec.ts runs 70 tests
green (was 67). Negative controls: dropping the `if (!target) return` guard in
settingsButtonClicked fails the settings case with `TypeError: Cannot read
properties of undefined (reading 'postMessageToWebview')`, the same for
marketplaceButtonClicked, and 70 pass again after each restore; the implementation
file's sha256 prefix is 09466c53b0429fe5 before the controls and after them.

Failed pre-merge checks:
- Regression Evidence:
Add a `focusInput` test with both surfaces tracked, a live sidebar provider, and
no live tab provider. Assert the `focusPanel` arguments and that neither
provider receives `focusInput`. Test that disposing the current sidebar clears
`getPanel()` and that disposing a replaced sidebar preserves the replacement.
- Lifecycle Resource Cleanup:
Give independent API task starts independent providers, or prevent duplicate
listener registration on a shared provider. Add a concurrent-start cancellation
regression test.

Issue (created at PR-open time): #1529
What
All title-bar commands (+ / Settings / History / Marketplace / popout / focus) resolve to a single surface-blind "visible" ClineProvider instance, and setPanel's mutual wipe of the sidebar/tab slots leaves stale references once a tab and the sidebar coexist. This PR makes each title-bar command target the instance its click originated from:

Pushed
bc39e81a5 -> 08225f581for the two reviewer threads (both replied and resolved):contributeslevel, where VS Code does not read palette visibility - the when clauses were inert. It now lives undercontributes.menus.commandPalette, and the four sidebar commands got complementarywhenclauses (activeWebviewPanelId != zoo-code.TabPanelProvider). This also closes the palette-with-only-a-tab-open case where the sidebar handler evicted the hidden sidebar's task while the tab did nothing: with a tab active the palette now offers the *InTab variant.getInstanceForView(tabPanel)returns undefined, the lookup is made and neither provider receives focusInput. Negative control: a sidebar fallback on the failed lookup reddens exactly this test; restore byte-exact (git hash-objectverified).Proofs at this head: registerCommands.spec 52 passed (was 51); eslint (CI command, full src) exit 0; package.json parses; diff touches only src/package.json and the spec.
Format gate follow-up: pushed
08225f581 -> 6a7ae11f6- the compile job's format:check step (prettier --check . at the repo root, added on main after this branch's base) flagged src/package.json and the spec; both are now prettier-clean at the repo config (part of the spec's formatting drift predates this PR and is normalized by the gate). No behavior change: spec still 52 passed, eslint (CI command) exit 0.
