Relayed from Leo's look at a transcript capture: "Queued-message controls. 'Send now ×' and the copy icon float loosely under the bubble. Align them to the bubble's edge."

What I found

On the current base, a waiting steer's controls already sit exactly where a sent prompt's controls sit. #31683 made that change (merged 2026-11-02 02:51 UTC). Before it, the waiting steer's row stayed in flow (#27580), so it sat inset from the bubble and took its own height. A capture from a build before #31683 shows the loose row.

I measured base with the shared footer test and the gallery, in Chromium at 880px and 360px, with short and wrapping prompts:

	Copy glyph right minus bubble right	Glyph top minus bubble bottom	Icon button
Waiting steer (Send now, ×, Copy)	0 px	8 px	28×28
Same prompt once sent (time, Copy, Retry)	0 px	8 px	28×28

The two steers in agent-pane.composer/steer-waiting-stack measure the same.

What this changes

Tests and gallery only. No CSS change.

• webviews/test/queued-user-footer.test.ts: the test checked only the outer row's box. It now also checks the controls in each width, length and theme case: Copy's glyph ends on the bubble's right edge, both while waiting and once sent. The glyphs keep the sent row's gap under the bubble. Every queued icon button and the sent Copy are the transcript-action-control square. If a change moved the controls inside a correct-looking row box, the old test would still pass, and this one fails.
• QueuedUserFooter.gallery.ts: adds a new stack variant with two waiting steers. Only the newest one offers Send now. The balanced and stack plays now check the same glyph alignment against the sent prompt in the same frame.

Design spec: leo-workspace design/chat-transcript.md, "A queued personal prompt stays right-aligned in the sent-prompt bubble position. Send now and the withdrawal × occupy the same footer slot directly under the bubble's right edge." Nothing in the spec changes.

Observed / Not run

• Observed on fast checks at this tree: CMUX_BROWSER_TESTS=1 bun test test/queued-user-footer.test.ts, 12 pass and 0 fail. Gallery plays for agent-pane.queued-user-footer compact, balanced, roomy, stack and read pass in dark and light. accepted fails its click step at base too, and this PR leaves it unchanged. vp lint and the type check are clean. One formatting fix was applied after that run.
• Not run: the native app build. The native host draws SF Symbols in place of the browser fallback glyphs, so pixel positions in the app may differ slightly from this harness.

Summary by cubic

Makes a forced Stop (cmux ended the turn because the agent never answered) read as any other stop, and a message steered in right after it draw below the stop instead of above it.

• The transcript line "The agent didn't answer Stop, so cmux ended its turn." is gone; a muted Stopped word in the footer (new stopped-turn-look experiment) replaces it, with the reason only in tooltips.
• A message logged after the Stop never reached the agent: it draws below the stopped turn's line and gives way to acpmux's later run of it (same promptId) or its queued card; a re-queue drops only that late steer, by promptId, or by its words when it has none.
• Continue on a stopped turn now has a tooltip and hides when a queued prompt runs next anyway.
• Tests, gallery fixtures, and a mock session updated to cover the forced-stop, late-steer, and queued-next cases.

Review (codex, router-review): SHIP at 91900c3

Reviewer: codex gpt-6-astra high, fast tier.

Follow-ups: 3. Each lands as an issue in this repo that links this receipt; the lane that opened the PR fixes it forward.

SHIP at 91900c3
Visual verdict: no images; Leo tries the build

1. [P2] [follow-up] direct.ts:6391: Match deferred messages by prompt ID before falling back to text. Two deferred messages with identical text but different IDs both disappear when only one is requeued. Reproduced with the extracted method; restrict text matching to rows without an ID.

2. [P2] [follow-up] App.tsx:7855: Account for prompts held after a failed turn. Their daemon hold is not represented by entry.held—that field represents local folder trust. If a failure pauses queued prompts, then the user sends and stops another turn, this guard hides Continue although those queued prompts cannot run automatically.

3. [P2] [follow-up] review/pr.body:18: Replace the stale “Tests and gallery only” description and unrelated queued-footer validation with evidence for this head. Supply stopped-turn screenshots; none were available.

The Bun suites could not run because Bun and project dependencies are absent.

Follow-ups:

• Preserve distinct prompt IDs during deferred-message cleanup.
• Keep Continue available when queued prompts remain paused.
• Correct the PR description and provide current validation and screenshots.

SHIP at 0499fd4

Visual verdict: no regression in the 16 supplied pairs; differences are spinner rotation only. New stopped-turn states aren’t pictured.

1. [P2] [follow-up] direct.ts:6406: Preserve steers already read before cancellation finishes. A sequence of stopping → steer → assistant reply → cancelled turn_result moves the steer below both its reply and the stopped summary, despite landSteer() having marked it read. Stop isn’t an immediate delivery barrier. Track delivery before terminal settlement and exclude those messages from deferral; add this sequence to the tests.

2. [P2] [follow-up] stoppedTurn.gallery.ts:44: Supply light/dark captures of the new stopped-turn variants, including late-message and queued-next states. The supplied images don’t show the changed footer.

The first finding was reproduced using the extracted reducer methods. Full tests could not start because @base-ui/utils/useIsoLayoutEffect is unavailable.

Follow-ups:

• Preserve placement of late steers read before cancellation completes.
• Capture the changed stopped-turn gallery states.

Awareness note from an agent lane that does not own this PR; it is not a review or a request to take the PR over.

---

Overlap awareness for this PR and #33248: #33543 changes only model.ts scrollLeadRanges plus focused scroll tests and an A/B runner. It leaves row-kind, status, Stop behavior, App.tsx, first paint, and initial rail entrance unchanged. The candidate is held for same-worker timing and strict slowdown/reversal coverage; no performance improvement is claimed. Its frozen head is fa55874. Please preserve the independent scroll-range function changes when integrating the overlapping model.ts work.

A newer verdict blocks 110ec68 (no independent SHIP at the head).

Visual verdict: no images; Leo tries the build

1. [P2] [follow-up] direct.ts:5989: The real daemon never delivers stopping through the requested transcript filter: TRANSCRIPT_MUX_KINDS excludes it, and live delivery uses that same filter. Consequently, lateSteers stays empty and messages still appear above the stopped summary. Include this event in the delivery path and test with production filtering.

2. [P2] [follow-up] App.tsx:7988: mergeQueue drops the daemon’s failure-related held flag, so paused prompts incorrectly make queueRunsNext true. Removing the shared resume action then removes Continue from failed autonomous turns, even though their queue cannot run. Preserve daemon holds and scope this suppression to stopped-turn controls.

3. [P2] [follow-up] stoppedTurn.gallery.ts:34: No after screenshots were supplied; capture the changed footer states when available.

Targeted Node probes reproduced findings 1–2. Bun and project dependencies were unavailable, so browser suites were not run.

Follow-ups:

• [P2] [follow-up] Fix find focus and align search overlay #1 Deliver stopping through production event filtering.
• [P2] [follow-up] Disambiguate Sentry environment between production and dev #2 Preserve held-queue state and error recovery.
• [P2] [follow-up] Release v1.13.0 #3 Supply footer captures.
