Explanation
The description provides detailed implementation context, issue references, design decisions, test results, limitations, and follow-up changes. It does not use the repository template headings or include the completed pre-submission checklist, but the required substance is mostly present.
Full details: Security Boundaries
-
Explanation
The changed paths only reroute fixed command actions to the provider that owns the sidebar or tab view, add view-identity checks, and scope disposal cleanup. The new commands accept no user-controlled arguments and do not add secret/PII handling, command execution, approval bypasses, or allowlist changes. Error logging in the new MDM fallback and post-message catches does not expose a newly introduced secret or PII path; the logged values are exception text.
Full details: Persistence Integrity
-
Explanation
No changed persistence path is present. The diff changes command routing, tab-panel reuse/serialization, and view-scoped disposal. The changed
plusButtonClickedpaths await task eviction, workspace refresh, and posts;postActionsonly sends UI actions. No changed storage write, non-atomic persistence operation, rollback path, or persisted-default propagation can be cited.
Full details: Lifecycle Resource Cleanup
-
Explanation
No concrete new lifecycle leak or duplicate-work path is evident. The changed tab-open path shares and clears its in-flight promise on success or failure, reuses a live tracked provider, and clears the tab reference only for the disposed panel. The changed sidebar path scopes message, focus, visibility, and configuration disposables to each view, then disposes only the old view's resources during replacement. Provider disposal cancels throttled work, queued tasks, pending probes, and tracked disposables, and getInstanceForView excludes providers after disposal starts.
-
Full details: Regression Evidence
-
Explanation
A changed sidebar-disposal branch lacks focused coverage. ClineProvider.ts:1163-1167 now rejects pending theme-fixture probes only when the disposed view is still the current view. The replacement-view test at ClineProvider.spec.ts:596-656 checks listener ownership, but it creates no pending probe and never verifies that disposing the stale view preserves the probe. The theme test at :1457-1465 calls clearWebviewResources directly, so it does not cover this conditional lifecycle path. A regression that rejects the replacement view's pending probe would pass.
Resolution
Add a ClineProvider unit test at the replacement-view layer. Resolve an old sidebar view, start a pending requestWebviewThemeFixture probe, resolve a replacement view, and dispose the old view. Assert that the probe remains pending and can resolve through the replacement. Also dispose the current replacement and assert that a pending probe rejects with the disposal error. This directly covers both sides of the new identity condition.

…isposals Pre-merge warnings on Zoo-Code-Org#1528: - Bidirectional independence is now pinned: resolving the sidebar after the tab keeps the tab as the tracked surface and focus target (the reverse order was already covered), and getPanel still reports the tab. - The sidebar disposal path clears the tracked slot with an identity check (clearSidebarPanel), so a late disposal of a replaced view cannot clear the replacement; focusInput/focusPanel resolve the sidebar through ClineProvider.getInstanceForView and skip a tracked-but-dead view instead of posting into it. Tests: registerCommands spec 55 passed, ClineProvider spec 211 passed. Local tsc shows only the worktree's pre-existing dependency contamination in untouched files (the changed files are clean); CI is the authority for the remaining environment-sensitive checks.

A replacement sidebar view can resolve before the old view disposal callback runs. The guarded clearSidebarPanel kept the slot, but clearWebviewResources() then disposed the replacement listeners from the shared array, leaving it tracked but deaf. Listeners are now recorded per surface; the sidebar disposal handler releases only the disposed surface listeners (and rejects theme probes only when it was the current view). Adds tests: replacement keeps every listener while the old view listeners are disposed, focusInput never hands a dead sidebar view to focusPanel, and the focusPanel command targets the tracked live surfaces.
The lint gate counts no-explicit-any per file with an exact suppression budget; the new test pushed the file one over. The fake view now uses a typed cast instead of any.
Some test doubles return undefined from mocked vscode registration APIs. The per-surface tracking and scoped cleanup now skip undefined entries, matching the guard the flat cleanup loop already had; without it 202 webview tests failed on dispose. core/webview suites 677 passed.
The remaining pre-merge warning asked for the focusPanel command test with a dead tracked sidebar: track the sidebar, make getInstanceForView return undefined, invoke the handler and assert focusPanel receives no sidebar. registerCommands 57 passed.

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:

Updated this round
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.
