Summary

Leo, on the running turn's live line ("Thinking · 1m 23s total · 3.2K tokens" drawn under "Sent a message, finished 3 background tasks, ran 5 commands"):

the indent looks bad

thinking shimmer not being at the bottom looks bad

Leo-ask: ask-f654b777b7
Reference: cmux-design-references cmux/live/transcript-activity-summary-thinking-row (and a second capture of the live line drawn above a waiting message's "Send now" row)

• Indent: the live line no longer pads its words to the icon rows' text column (.cv-worked.cv-worked--live, added in Agent chat: every status row's words on one column; session names read as words #33157). Its words now start on the icon column, the transcript's left edge, the way the shimmer sits in the Claude and ChatGPT apps, so it no longer reads like a second line of the row above it. The empty-slot marker data-lead-slot and the gallery icon-column invariant's handling of it are gone too: the invariant now reads the line's words like any other text row.
• At the bottom: App.tsx used to append the waiting-messages group ("N messages from M sessions") and held guest prompts after the running turn's live line, so the shimmer sat above them. withWaitingRows (conversation/pendingMessages.ts) now puts them above a trailing live line (isLiveLine, model.ts). The line stays the last row, the same way a held prompt already sits above the line inside its turn.

Risk: small and contained (CSS, one row-order helper, comments). Nothing changes for an ended turn. Spacing stays the same because the live line under the group's head is still "one more line of the run" (isLiveStep).

Design spec: design/chat-transcript.md ("One icon column": the live line now starts on the icon column).

Test

bun test src/agent-session/acpmux/conversation/pendingMessages.test.ts: the new test "the waiting messages draw over the running turn's live line" fails on base, where withWaitingRows doesn't exist and the group was appended after the line, and passes on the head (22 pass).

Observed / Not run

• Ran: the test file above; scripts/web-lint.sh.
• Not run: the gallery advisory run and a DEV build capture. Leo will try the build.

Changelog

• Changed: The agent's live "Thinking" line now starts at the transcript's left edge and stays the last row, below waiting messages.

Summary by cubic

The live Thinking line now starts at the transcript's left edge and stays the last row, below waiting-message groups and held prompts. Its spacing is unchanged, and ended turns still place waiting messages at the end.

Review (subagent claude-opus-5-5 medium): SHIP at 14e9fcb

Checked row order, isLiveStep spacing, footer marks, Find and types; the first pass caught a readonly/mutable type error, fixed at this head.
Follow-ups: when a turn ends with waiting messages still shown, the group moves down one footer line (rows go from [group, live] to [footer, group]).

BLOCK at 14e9fcb
Visual verdict: no images; Leo tries the build

1. [P1] [blocking] conversation.css:2098 — Update webviews/test/transcript-status-text-column.test.ts:105. Both variants still require the live words to align with icon rows’ text within 0.5px. Removing the inset moves them 24px left, breaking those browser tests.

2. [P1] [blocking] pendingMessages.ts:95 — Update the spacing tests and their tables for the reordered neighbors. transcript-spacing-table.test.ts:181 and transcript-spacing-kinds.test.ts:265 still measure waiting-minus-live and expect positive 22px; placing waiting above live makes that distance negative.

These failures follow from the unchanged assertions; execution was unavailable because Bun/bunx are absent.

Follow-ups:

3. [P2] [follow-up] Thinking.tsx:221 — Provide after screenshots covering alignment and ordering with waiting messages and held prompts.
