Review Change Stack

📝 Walkthrough

Walkthrough

The PR generalizes desktop E2E harness runtime preparation, adds window resizing and plugin preview commands, strengthens E2E synchronization, and updates sidebar pinning and scroll behavior with regression coverage.

Changes

Desktop E2E runtime and regression flows

Layer / File(s) Summary
Generic harness runtime preparation
wework/e2e/desktop/modules/desktop-build-flows.mjs
The build flow extracts and validates the configured harness runtime, uses generic preparation and bundling names, exports the helpers, and enables window-size capability.
Desktop E2E automation controls
wework/e2e/desktop/modules/shared.mjs, wework/src/e2e/automation.ts
The E2E flow supports a configurable result root, logical main-window resizing, and validated plugin import previews.
Desktop regression synchronization
wework/e2e/desktop/modules/task-flow-main.mjs
The sidebar regression flow waits for overflow metrics, tests a non-edge scroll position, and verifies position preservation after refresh.
Embedded-browser request synchronization
wework/e2e/desktop/scenarios/embedded-browser-multi-tabs.scenario.mjs
Fixture A tracks request starts so reload and recovery checks wait for the expected request before asserting loading state and release held responses during cleanup.

Desktop sidebar task state

Layer / File(s) Summary
Serialized optimistic task pinning
wework/src/components/layout/DesktopSidebar.tsx, wework/src/components/layout/DesktopSidebar.test.tsx
Pin mutations now use per-task ordered chains, persisted-state reconciliation, acknowledgement handling, and failure handling. Tests cover stale refreshes, rapid pin/unpin actions, external updates, and failed requests.
Current-task row visibility
wework/src/components/layout/DesktopSidebar.tsx, wework/src/components/layout/DesktopSidebar.test.tsx
Automatic scrolling now depends on current-task identity and rendered row visibility. Tests cover scroll preservation during refresh and scrolling when the active task changes.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 4482d

This change preserves manual sidebar scrolling while retaining automatic task positioning, but rapid pin changes can still show stale state or reapply an earlier override, and related regression checks have synchronization weaknesses. The PR is not merge-ready until the pin-state race is fixed or explicitly accepted, with the remaining runtime and test issues requiring owner follow-up.

3394-3410: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Retain and retire pin mutations per task.

Line 3399 replaces the prior pending mutation for the task. If a user pins and then immediately unpins before a runtime refresh, the second mutation uses the stale persisted value as its base. When the refresh later reflects the first pin request, Line 3406 ignores the latest unpin intent and renders the task as pinned.

Successful mutations also remain in runtimeTaskPinOverrides. If a later runtime update returns the original base value, the retained override becomes active again and can reapply an obsolete pin state.

Store an ordered per-task mutation chain, or equivalent acknowledged state. Derive the visible value from the committed runtime value plus pending mutations. Remove a mutation only after runtime data reflects its requested value. Add coverage for rapid pin/unpin requests and for a later external pin-state update.

Stop polling when the dialog wait times out.

withTimeout rejects its race but does not cancel the while loop. After a timeout, the loop continues to call getElementCount during failure handling and teardown.

Use waitFor with visible: false so the command owns the timeout.

Proposed fix
-      await withTimeout(
-        (async () => {
-          while (
-            Number(
-              await control.command('getElementCount', '[data-testid="continue-im-dialog-overlay"]')
-            ) !== 0
-          ) {
-            await new Promise(resolvePromise => setTimeout(resolvePromise, 50))
-          }
-        })(),
-        DEFAULT_STEP_TIMEOUT_MS,
-        'The single private IM session dialog did not close after automatic binding'
-      )

3481-3546: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Consider extracting the pin mutation queue into a dedicated hook.

The serialization logic is correct: the chain preserves request order, .catch(() => undefined) keeps the chain alive after a failure, the failure path removes only the matching requestId, and the finally block clears the chain entry only when it is still current.

The concern is placement. DesktopSidebar.tsx is about 4,900 lines, and this layer adds roughly 90 more lines of queue orchestration with three inline state updaters inside the component body. A hook such as useRuntimeTaskPinQueue(onSetRuntimeTaskPinned) that owns runtimeTaskPinOverrides, the request chains, the revision counter, and the persisted-state cache would expose a small interface (getPinnedValue, setPinned, syncPersistedState) and allow direct unit tests of the ordered-mutation logic without rendering the sidebar.

As per coding guidelines: "Favor cohesive modules, explicit interfaces, and standard practices. Split files over 1000 lines."

Add coverage for a rejected pin request.

This test covers only resolved requests. The changed failure branch in DesktopSidebar.tsx (lines 3527-3540) removes only the mutation with the matching requestId and keeps later queued intents. That branch is the one most likely to regress, because the earlier implementation cleared the whole override on failure.

Add a case where the first queued request rejects while a second intent is still pending. Assert that the second intent still drives the rendered pin state and that the chain issues the second request.

Add a positive assertion between the two clicks.

Line 2429 asserts that sidebar-pinned-section is absent. That assertion also passes if the first optimistic pin never applied. Assert the pinned state after the first click, then assert its removal after the second click. The test then proves both transitions.

Validate both paths at runtime.

The type assertion does not validate parsed JSON. Truthy non-string values can pass Line 1714 and reach local_executor_preview_plugin_import, although the executor contract requires string paths. Reject non-string and blank values before invoking the executor.
