Leo, 2026-11-01, on a screenshot of "Ran grep -n -E 'environ|GH_QUOTA_[A-Z_]+|low_water' …" with "Thinking 15s · ↓ 284 out ↑ 342.6K in" on its own line under it:

this should be replacing the thinking area and its shimmer across things

like the thinking or whatever it should just keep going

and shouldn't flicker

What changed

A running turn now has one live line at the bottom, and that line is the current activity:

moment	before	after
before any output	Thinking 15s	Thinking 15s
a call runs	Running grep … 0s (the clock started again at the call)	Running grep … 15s · tokens
the call is done	row "Ran grep …", then "Thinking 18s · tokens" under it	Ran grep … 18s · tokens (one line, shimmering)
the agent thinks after it	as above	Ran grep … 21s · tokens
the next call runs	Running sed … 0s	Running sed … 24s · tokens, and "Ran grep" moves into the run above

• conversation/turns.ts codexLiveTurn / liftedStep: between calls the line names the latest finished step instead of going back to "Thinking". That step leaves its run so it reads once. Failed, backgrounded, message, sub-session, render and edit calls keep their own rows and do not go on the line.
• conversation/Thinking.tsx: one clock, the turn's time from the prompt, for every step, so the time no longer starts again at each call. The turn's tokens now show beside a call too. A finished step reads "Ran …" and offers no ⌃B.
• The line keeps its one id (thinking-live) and the same element tree for every state. Only its text changes, so React never remounts it and the CSS shimmer never starts again.

Spec: leo-workspace design/chat-transcript.md, "The live line" (added alongside this PR).

Proof: per-frame trace

webviews/test/transcript-live-line-continuous-browser.test.ts (real Chromium, cmuxAfterPaint reads every painted frame). A turn steps through Thinking → grep running → grep done → a thought → sed running → sed done, 12 frames each. Across every frame it asserts:

• one line element and one shimmer band element;
• the band's animation time only moves forward (no restart);
• words and a time on the line in every frame (no blank frame);
• the turn's clock (never under the 15s already elapsed, never going back);
• "Ran grep" and "Ran sed" between calls, never "Thinking".

The trace it prints is below.

Head (green), every painted frame:

Tests

Base fails and head passes:

• the trace test, red on base (the clock reads "0s" at the call, the line reads "Thinking" after a call);
• bun test test/transcript-codex-live-line.test.tsx test/transcript-running-live-line.test.tsx test/transcript-working-line.test.tsx: 46 pass on head. These tests encoded the 2026-10-20 spec ("Thinking -> Running -> Thinking", a clock per call) and now encode Leo's new one.

Observed / Not run

• Observed: every unit test file that touches the live line or the Thinking component passes when run on its own (32 files). vp fmt and vp lint (with type checks) are clean on the changed files.
• The browser trace runs through cmux-ci, because this VM skips browser lanes. Result: 1 pass at head (run 41264916394). With the source reverted to base it fails, 0 pass and 1 fail (run 41265476768): the clock reads 0s at each call and the line reads "Thinking" after a call.
• Not run: a DEV build. That is the next step after this lands.

Follow-ups (from review)

• The lifted run's version (10v+3) can equal the ended open fold's (5v'+3) if one snapshot ends the turn and doubles that run's version. It needs a run state of its own, and the minimap test's pinned versions have to move in the same PR.
• Find counts a match on the call the line names but cannot reveal it until the next step. Range copy has the same gap.
• When a run held only the lifted call, its row leaves and comes back at the next call.
• The no-plan and merged-run fixes from review are in (joined, no lift with a todo list).

Changelog

• Changed: A running turn shows one live line that names the latest step (Running/Ran …) with the turn's time and tokens, instead of a separate Thinking line.

Review (subagent claude-opus-5-5 medium): SHIP at b1294f6

Three rounds:

• 427e775: SHIP with follow-ups.
• 58cefe8: BLOCK. RUN_STATES 6 broke minimap-card-metadata's pinned versions.
• b1294f6: SHIP. The revert brings back RUN_STATES 5 and the lifted run's v*2+1. The no-lift-with-a-todo-list fix and the merged-run (joined) fix stay.

At b1294f6, six focused files pass (67 tests): minimap-card-metadata, transcript-codex-live-line, transcript-running-live-line, transcript-live-runs, transcript-working-line and transcript-consolidated-runs.

Follow-ups (non-blocking, in the PR body):

• The lifted run's version can collide with the ended open fold's in a narrow case.
• Find can count the lifted call but not reveal it.
• A one-call run leaves and comes back.

Base reds, not this PR's own. All three are reproduced on the base tip.

cmux-next checks fails on two items, and neither touches a file this PR changes (it changes only webviews TS and its tests):

• tests/test_cmux_next_checks_workflow.py test_every_part_of_bun_run_check_runs_in_the_warn_branch: "bun run check:session-info-names ... does not run when CMUX_NEXT_STYLE_GUARDS=warn". At feat-cmux-next 08c0011 it fails the same way: FAILED (failures=1), 165 tests.
• scripts/lint-ios-package-conventions.sh: namespace-type in Packages/macOS/CmuxNext/Sources/CmuxNextAgentPane/AgentPaneHandoffPrompt.swift:11. At 08c0011 the same ERROR line appears.

health (2) and health (3) report "1 red state(s) render or are red another way on base 94a9a59: agent-pane.transcript#tool-result-envelopes", which is a base red by the job's own wording.

release-notary and Guard status are guard-status base reds.

Review (subagent claude-opus-5-5 medium): SHIP at bd1ce43

Source unchanged since the SHIP at b1294f6; the delta b1294f6..bd1ce43 touches only five webview tests, each adapted to the intended behaviour (a finished last call stays on the live line instead of a row). No assertion weaker than the change requires.

Follow-ups:

• peer-chat: after completed, assert the line still reads "Run make" with the time.
• stream-jitter: expect(left).toBeGreaterThanOrEqual(-1) in the tool-ending branch.
• subagent-groups-open: STALE test also waits on "Read tests.ts" before the no-groups check.

Verdict-named tests at bd1ce43 (cmux-ci run 41278616620): subagent-groups-open green; stream-jitter's only fail, "the reply only moves up as a tool call, the working line and the queue card come and go", fails the same way with base source (run of job 124762770402, reverse-patched), so it is a base red.

Review (subagent claude-opus-5-5 medium): SHIP at fbfd657

Delta since the SHIP at bd1ce43 (and cmux-bot's base merge ff392ce): one gallery fixture. agent-pane.transcript#tool-result-envelopes is a working turn whose calls all finished, so the live line took its last call and the play found one row fewer; a reply under the calls keeps every call a row. Its play and checks are unchanged.

Gallery health, agent-pane.transcript and agent-pane.transcript-view at fbfd657 vs the same tree with this PR's src reverse-applied (cmux-ci, this lane): tool-result-envelopes renders at head; transcript-view#verbose ("Verbose did not draw .cv-command[aria-expanded=true]") is broken identically on base source, so it is a base red.

Follow-ups:

• mcp-calls (no play): its last finished call MCP_READ now sits on the live line instead of a row; check the render and add a reply if the read should stay a row.
