Fix Android showcase capture and rebuild v2 queued rows

[juliusmarminge]

Android showcase capture

The Android job failed two seconds after the environment server started, printing a single line with no stack:

cannot rollback - no transaction is active

That is the masking error, not the failure. The seed opens state.sqlite while the server it just started is still writing, so BEGIN IMMEDIATE loses the write-lock race and returns database is locked — and the catch block's unguarded ROLLBACK then threw over it. A local probe against a freshly-started server reproduces both strings verbatim:

{ "ok": 39, "busy": 1,
  "firstError": { "original": "Error: database is locked",
                  "masked":   "Error: cannot rollback - no transaction is active" } }

1 failure in 40 attempts on an idle Mac; 0 in 120 once the connection carries a busy timeout. On a Linux runner with an emulator saturating the CPU it hit on the first try. So: a 30s busy timeout on the seed connection, a guarded rollback so the real error survives, and stack output from the harness — it only fails in CI, where the line that threw is the whole diagnosis.

Queued rows in Thread List v2

Queued tasks rendered in v2 with the v1 row design — bold text-lg title, zinc "Pending" pill, chevron — so the one row you cannot act on shouted louder than the live work above it. They now use the v2 card idiom (project line, title, branch · machine) under a "Pending" divider mirroring "Settled", with Queued in the status slot. The label stays uncolored: v2 reserves hue for act-now, in-motion, and broken, and a queued task asks nothing of the user. v1 keeps its own row unchanged.

Showcase fixture

The fixture had no settled threads, so the list screenshotted as one undifferentiated block. Three are seeded now (one per project, 5h / 28h / 2d) with an explicit settled_override, and the oldest unlabeled active thread was dropped so the settled tail starts above the fold on a phone. The fixture test asserts every project contributes to both the active block and the settled tail.

Verification

environments and threads scenes captured locally on iPhone 6.9 and iPad 13 — pending, active, and settled all render, on both the compact list and the split-view sidebar. Android was not captured locally (build cancelled); this branch needs a workflow run to confirm that leg.

Typecheck, lint, format, and 760 tests (scripts + mobile) pass.

Note

Low Risk
Changes are limited to mobile thread-list UI (v1 unchanged) and dev/CI showcase seeding; no auth, payments, or server API behavior.

Overview
Thread List v2 moves offline queued tasks out of the list header and into the flat list via shared buildThreadListV2ListItems, ordered active → pending → settled with a Pending section divider (same pattern as Settled). Home and the iPad sidebar both render them with new ThreadListV2PendingRow instead of v1 PendingTaskListRow. ThreadListV2SettledDivider becomes ThreadListV2SectionDivider with a label prop.

The v2 empty state no longer treats pending-only queues as “non-empty” (those rows live in the list body now). FlatList/LegendList extraData also includes project maps so rows refresh when project shells load after first paint.

Showcase / CI: seeding opens SQLite with a 30s busy timeout, uses a guarded ROLLBACK so lock errors aren’t masked, seeds settled threads for screenshots, and the showcase harness prints stacks on failure.

Note

Fix Android showcase capture and render queued pending tasks inline in thread list v2

• Introduces ThreadListV2PendingRow in thread-list-v2-items.tsx to display queued pending tasks with project info, status label, branch, and a delete action via context menu.
• Adds buildThreadListV2ListItems in threadListV2.ts to splice pending tasks between active and settled thread items, marking the first pending item to draw a 'Pending' section divider.
• Updates both HomeScreen and ThreadNavigationSidebar to use the new builder, replacing manual list construction and adding project metadata to extraData for correct row invalidation.
• Extends the showcase seed script to support settled threads and fixes SQLITE_BUSY resilience and ROLLBACK error masking in mobile-showcase-environment.ts.
• Behavioral Change: FlatList item shapes in v2 lists change to a discriminated union (v2-thread | v2-pending) with a new item.key extractor; pending task rows move from the header into the list body.

Approvability

Verdict: Needs human review

This PR introduces new UI components and changes how pending tasks are positioned in the thread list (moved from header to inline between active/settled items). While well-tested and contained to presentation logic, the behavioral changes to list ordering and empty states warrant human review.
