The mobile thread list still read like a compact agent tray: snoozed/settled collapsed into slim rows, and snooze wake time looked like a normal age stamp. Hard to scan the way you scan Mail.

Rows are now title-first Mail cards on both platforms (same info: title, project/env, preview when present, date), snoozed and settled use that full card, and snoozed trailing time is a wake countdown with a clock.

Before / after (iPhone 17 Pro)

Before After
before after

Test plan

  • Open Chats on iOS; confirm title-first cards with muted project under the title
  • Expand Snoozed; confirm full cards and blue clock + wake relative time (not last-activity age)
  • Expand Settled; confirm the same full card chrome (not slim)
  • Spot-check Android for the same layout (shared code path)
  • vp run check:changed

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Mobile thread lists now show Mail-style rows with message previews, including for settled and snoozed threads. Human review is needed to confirm the new default content visibility and list density.

Walkthrough

Thread-list rows now use a card-style layout across active, snoozed, and settled threads. The change adds message previews and updates row status, accessibility content, swipe actions, spacing, and estimated item heights.

Changes: Thread list row update

Layer / File(s) Summary
Row state and data
apps/mobile/src/features/threads/threadListV2.ts, apps/mobile/src/features/threads/threadListV2.test.ts
Swipe actions and row selection now use thread settlement state instead of row variant. Message previews normalize whitespace and identify the speaker. Timestamp and move-availability rules also use thread state. Tests cover message previews, timestamps, and settled rows.
Unified row presentation
apps/mobile/src/features/threads/thread-list-v2-items.tsx, apps/mobile/src/features/threads/thread-list-v2-row-appearance*, apps/mobile/src/features/threads/ThreadNavigationSidebar.tsx, apps/mobile/src/features/home/HomeScreen.tsx
The row component uses one card-style layout with status details, contextual labels, and message previews. Row spacing and estimated item heights increase. The compact slim-row presentation and former “Done” status label are removed.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

  • pingdotgg/t3code#32634: Extends the same Mail-style V2 list and updates card-row rendering and estimated row heights.
  • pingdotgg/t3code#13149: Moves V2 row data, including timeLabel, onto recyclable list items and uses a 72-pixel row estimate.

Merge Risk: Low · up to f1ca0

Screen-reader users get no spoken status for threads that are working or waiting. Sighted users see the status icon and duration. This is a bounded accessibility gap with a small fix. The layout and divider changes otherwise look sound, though device checks were not run.

Takeover update:

  • Merged current main (merge commit, no rebase). The only conflict was threadListV2.test.ts: kept this PR's preview and unread-date tests, kept main's new swipe-action test with settled: false in place of the removed variant input, and updated the relocated queued-thread test to expect card for settled rows.
  • Fixed the CodeRabbit divider inset: the hairline now starts at the text column and scales with the avatar instead of a fixed 68px.
  • Mobile typecheck and threadListV2 / useThreadListV2 tests pass. Not checked on a device.

Takeover update:

  • Rebased onto current main (dropped the earlier merge commit). Conflicts were in thread-list-v2-items.tsx and threadListV2.test.ts.
  • Kept Mail-style cards and restored main's tabular working/waiting timer (#33447) so the duration no longer reflows the title.
  • Review threads were already resolved; no unreplied findings left.
  • vp run check:changed and threadListV2 tests pass locally. Not checked on a device.

Assert the settled primary action in the existing swipe-action case.

This PR changes the primary action of resolveThreadListV2SwipeActions. The action now comes from settled, not from the row variant. The existing case passes only settled: false and asserts only .secondary. No assertion covers settled: true → primary: "unsettle" or settled: false → primary: "settle". If a later change inverts or drops the settled branch, settled rows swipe to "Settle" and no test fails. Add two assertions to this case. Do not add a new it.

🧪 Proposed assertions

     expect(
       resolveThreadListV2SwipeActions({
         settled: false,
         settlementSupported: true,
         snoozeSupported: true,
         snoozable: canSnooze(thread, { now: NOW }),
       }).secondary,
     ).toBe("snooze");

+    ).toBe("unsettle");

As per path instructions, the testing rules say: "Extend an existing test or table before adding a new case". Request a test "only when it would catch a real regression".

Minor · Functional Correctness · Quick win

Announce the working and waiting states in rowAccessibilityLabel.

STATUS_LABEL_BY_STATUS.working.label and STATUS_LABEL_BY_STATUS.waiting.label are null. For those statuses, statusLabel?.label ?? null adds no text. The statusLabel === undefined guard also drops the time label. VoiceOver and TalkBack read only the RowPressable label. A screen-reader user therefore gets no status for a working or waiting thread. A sighted user sees the status icon and the duration in the trailing slot. Use a spoken fallback when the visual label is null.
