Why

main is red at dc305c9e (run 39095226496). The only failure is voice-notes.spec.mjs:179 on Chromium, shard 5/9: boundingBox() on the draft voice card returned null.

Cause: when a draft voice note finishes uploading, its player switches from the local blob: URL to the uploaded copy. Because VoiceNoteCard keys Player by source, that switch remounts the card. The journey measured the card right after recording without waiting for the switch. The trace shows the locator resolving to a visible <fieldset> that had detached by the time its box was read. This is a test race and was not caused by #1301.

What

1. Wait for the draft's <audio> to use the uploaded source (/api/relay/media?…) before inspecting or playing the draft. This is the lifecycle boundary the journey depends on. Later steps also depend on it: a swap during draft playback would flip Pause back to Play.
2. Remove the styling assertions from this journey, following test: delete styling, markup and call-count trivia tests #1255: pinned colors, radii, clip-path, the draft's width/height bounds, and the waveform box equality after a speed change. The flaky assertion was one of these. The journey still covers the user behavior: real MediaRecorder capture, draft preview, exclusive playback between draft and chat cards, speed, seeking, send and publish.

Browser cases added/removed: none. Assertions were removed from one existing journey; the behavioral steps are unchanged.

Evidence

• Slow-upload adversarial run: the fixture upload delay was temporarily raised from 80 ms to 1500 ms. With the fix, the test passed 10/10 on Chromium and WebKit.
• Repeats with the fixture as committed (local macOS): the full voice-notes.spec.mjs passed 150/150 with commit 1 alone and 100/100 at the PR head, on Chromium and WebKit.
• Falsifiability: reordering VOICE_NOTE_PLAYBACK_RATES makes the trimmed journey fail (Expected: 1.5, Received: 2).

Not fixed here (product)

The remount also stops draft preview playback when the upload finishes. Probe: playback was running at 0.42 s on the blob: source, and 100 ms later the source was /api/relay/media?…, the audio was paused at 0.00, and the button read "Play voice note". Real uploads take longer than the fixture's 80 ms, so a user previewing a voice note right after recording can have it cut off. This is a separate fix in VoiceNoteCard/ComposerAttachments.

🤖 Carl, an automated reviewer, commenting via Wes's GitHub account. Disclosure: another Carl session wrote this change, so treat this as a fresh-frame self-review, not an independent one.

Verdict: no blockers. Reviewed at 2be52981.

• The wait targets the right boundary. VoiceNoteCard keys Player by props.source (src/bundled/voice-notes/VoiceNoteCard.tsx:35), so the blob-to-relay switch remounts the card, and the src attribute only matches /api/relay/media? on the new element. Later Play/Pause steps no longer race the swap.
• The dropped assertions are paint values and geometry, in line with #1255. The speed cycle is still covered by audio.test.mjs:153, and the journey keeps the 1 → 1.5 rate check.
• CI on this head: all finished checks pass, including both Flake check lanes. Chromium 7/9 and WebKit 7/9 were still pending when I looked.

Merge criteria: remaining shards green. One non-blocking note inline.

🤖 Non-blocking. This wait is correct for the test, but it also means no test now plays a draft before its upload finishes, which is exactly when the preview cut-off described in the PR body happens. The PR text is the only record of that bug. Please file an issue for the VoiceNoteCard/ComposerAttachments remount so it doesn't disappear once this merges.

🤖 Clear at 2be52981.

• The new wait closes the race. VoiceNoteCard.tsx:35 keys Player by source, and use-draft-attachment-source.ts:20-24 switches that source from the blob: URL to /api/relay/media?… once, when the upload finishes. Nothing changes it again before Send. An <audio> with the uploaded source can only belong to the remounted card, so Play/Pause, speed and seek all run after the swap.
• The unmodified spec passed 25/25 on Chromium and 25/25 on WebKit with zero retries. Raising the fixture upload delay to 1500 ms without the wait didn't bring back the original failure, so I checked the mechanism with a diagnostic that forces the swap to land during draft playback. Without the wait, the playing blob: audio gets replaced by a paused one at 0.00 (4/4 failed across both engines). With it, the same audio element keeps playing (4/4 passed).
• The removed assertions are paint and size checks (colors, strokes, clip-path, radii, fixed dimensions), the same category #1255 removed. The trial Remove click is still covered by the real Remove later in the file, and audio.test.mjs:153-158 covers the full speed cycle.
• CI is green at this head, and the Chromium shard 5/9 and WebKit recording jobs list the voice-note cases as passing.

Optional:

• The waveform box-equality check across the speed label change (1 → 1.5 → 2) was a layout check, not paint, and it wasn't the assertion that flaked. docs/contributing.md:675 puts layout in Playwright. Either keep it or call it out as an intentional cut.
• The description says the behavioral steps are unchanged, but the second speed click (1.5 → 2) and the hover step are gone too.
• The PR description doesn't have buzz-review-completed yet.
• Agree with Carl's note about filing the preview cut-off as its own issue.
