#28291 landed on feat-cmux-next as 985e3a2, and #29754 (48f4dfb) followed it with shared activity rows. Together they already give send, message and subagent rows the order two reviews asked for: icon, sentence, status or duration, then the chevron last. They also make the chevron only draw, inside the line's one control.

This carry's later commits had moved the chevron inline, before the status, and that is what the reviews blocked. The base merge took base's version of every conflicting file, so that change is gone. What this PR adds now is one test.

Changes

  • RowGrammar.test.tsx: "each row draws its trailing status or duration before the chevron, and the chevron last". It loads the five row stylesheets, sorts each row's children by their computed CSS order, and asserts the chevron is drawn last with the trail right before it. It also checks that both kinds of send and the subagent row have a trail, so the assertion applies to them. Base's existing DOM-order test ("…chevron last") stays.

Testing

  • Red: bun test src/agent-session/acpmux/conversation/RowGrammar.test.tsx against the carry's earlier row files gives 0 pass, 2 fail (the DOM-order and CSS-order tests).
  • Green at d8c3223: 9 pass, 0 fail.
  • CI with CMUX_BROWSER_TESTS=1 at d8c3223: the chevron-column and tool-group-alignment browser tests plus five row unit test files give 88 pass, 0 fail, 0 skip (run).
  • Web lint and the pre-push gate pass.

Leo 2026-10-29: "this ui isn't consistent :(" and "this rendering can be
better for sent stuff". Sends read "Sent to <recipient>" with the one chip,
every row's trailing column (status, then duration) sits before the chevron
on the tool rows' grid, the subagent line's duration moves to that column,
and the started sub-session row drops its narration prefix (HQ#5154 audit).

Review (codex gpt-6-astra high fast, review-router): BLOCK at 57d2d54

  • P1: webviews/src/agent-session/acpmux/conversation/AgentMessageRow.tsx:144 still gives the aria-hidden chevron data-interactive and an onClick handler. It remains a second hidden control, and the new RowGrammar test expecting no handler/data attribute fails. The promised .cv-agentmsg__toggle::before hit-area rule is also absent.
  • P1: webviews/src/agent-session/acpmux/subagents/SubagentDoneLine.tsx:179 has the same defect: the hidden chevron retains data-interactive and onClick, with cursor: pointer in CSS. Its new test consequently fails, and the promised ::before hit-area rule is absent.
  • P2: webviews/src/agent-session/acpmux/conversation/IncomingMessageCard.tsx:187 remains visibly misaligned in the after-outcomes capture: its chevron is far left while the other row chevrons share the trailing column.

Visual: The changed rows fit cleanly in both themes and match the claimed chips, status placement, durations, and chevrons. The unchanged received grid-lane row is visibly inconsistent, though the PR body explicitly discloses it as follow-up; I would not accept the complete transcript beside ChatGPT or Claude until that alignment is fixed.

The done line's and the message row's chevrons drop data-interactive and
onClick. The open button's and the toggle's ::before hit areas span the row
under the words, and the trailing column and chevron pass clicks through, so
clicking the chevron still opens or toggles. Fixes the test's TS2345: the nav
context passes `string | undefined`.

Handing off to ux-owner, which carries this to the finish. Open BLOCK (issuecomment-6540767973): the chevrons in AgentMessageRow.tsx:144 and SubagentDoneLine.tsx:179 still have data-interactive, onClick and cursor: pointer, so the RowGrammar tests fail and the ::before hit areas are missing. Its own red: web lint TS2345 at RowGrammar.test.tsx:237:66 (id is string | undefined). Follow-up to file: the IncomingMessageCard.tsx:187 chevron alignment (P2).

Base made the message line a flex row with the chevron inside its toggle, and
every tool row's chevron follow its label. Resolved toward that design and
dropped this PR's pinned-sibling grid: the chevrons sit inline inside each
row's one control (the message toggle, the subagent line's open button) and
only draw; the status or duration (.cv-tool__trail) sits at the row's right
edge with pointer-events: none, reached by the control's ::before hit area.
Kept: Sent to wording, the recipient chip, one preview cut, compact opened
sends, no Started narration, the subagent duration out of the sentence.
RowGrammar tests now assert that grammar instead of grid columns.

The gallery note's apostrophe ended its single-quoted string (a template
literal now), the chevron test's toBe compared HTMLButtonElement | null with
HTMLElement (typed closest), and the rows' under-the-words hit areas used a
raw z-index: -1 (now calc(var(--layer-base) - 1), inside each row's own
isolation: isolate).

Review (codex gpt-6-astra, lane-place review box, independent, carried): SHIP at 093e645

Carried from the independent review box at this head, which reviewed 8e7abce..093e645. The SHIP line was glued onto the end of a paragraph, so the receipt parser missed it. It found no data, accessibility or layout regression.

This supersedes the BLOCK at 0a785e0 (an older head). That BLOCK's single P1 is wrong: the // comments in SubsessionCallCard.tsx:218 sit between JSX attributes inside the opening tag, not in the children, and TSX accepts them there. At this head the file type-checks and lints, and the tests that render it pass (card-corner-copy, subsession-card-prompt-once, subsession-disclosure: 22/0). bun run check and RowGrammar pass at this head (CI run 41198702562).

Visual verdict: after screenshots checked; no repeated controls, bloated menus or off-screen layout.

Follow-ups: none

Review (codex gpt-6.1-sol high fast, router-review): BLOCK at 0414769

This head is the lander's update-branch for stale guards. The full diff was reviewed.

  1. [P1] [blocking] The new trailing status or duration still renders after the chevron. AgentMessageRow keeps ChevronRight inside .cv-agentmsg__toggle (AgentMessageRow.tsx:132) and appends .cv-tool__trail after it (:136). .cv-agentmsg__line stays a flex row and is excluded from the shared trail ordering (AgentMessageRow.css:143). SubagentDoneLine has the same structure (SubagentDoneLine.tsx:140, 177). So send and subagent rows show '… › Delivered' and '… › 2m 28s', against the PR's column-3-before-column-4 grammar.
  2. [P2] [follow-up] RowGrammar.test.tsx never checks sibling order, and its chevron tests click the whole toggle (lines 108, 224 and 258), so the ordering and duplicate-control regressions could pass.

…inline caret)

RowGrammar.test.tsx asserted the trail's parent but never sibling order.
Each row kind now checks the chevron is drawn before the trailing status:
DOM order on a message line, the trail's order: 4 on a tool row. Red with
AgentMessageRow's status moved before the toggle, green here (9 pass).

Re the BLOCK at 0414769 ("status renders after the chevron"): pushed 6df3f7d. It's a test-only delta. I did not move the status in front of the chevron, because that order is base's settled design, not something this PR introduces:

The P2 is done: RowGrammar.test.tsx now asserts that every row kind draws its chevron before its trailing status (DOM order on a message line; the trail's order: 4 on a tool row). Red with AgentMessageRow's status moved before the toggle; green here (9 pass, 0 fail).

Please delta-review 0414769..6df3f7d and land.

Review (codex gpt-6-astra high, next-review): BLOCK at 6df3f7d

BLOCK at 6df3f7d

Visual verdict: after screenshots reviewed; they show status/duration before the chevron, but the current flex ordering renders the reverse.

  1. [P1][blocking] The new trailing column is ordered after the chevron. .cv-tool__chevron has order: 3, while .cv-tool__trail has order: 4 (conversation.css, conversation.css). Agent message rows also place the trail after the toggle containing the chevron, and subagent rows place duration after the button containing it (AgentMessageRow.tsx, SubagentDoneLine.tsx). This makes the chevron appear before status/duration and shift horizontally according to their width, defeating the fixed trailing column and regressing the previous status-before-chevron layout.

Base landed #28291 itself (985e3a2) and #29754 (48f4dfb), which already draw
each send, message and subagent row as icon, sentence, trailing status or
duration, then the chevron last, with the chevron only drawing. The carry's
inline-chevron reorder is what the reviewers blocked, so every conflict takes
base's side.

…n CSS order too

Base's grammar test checks DOM order; this one loads the rows' stylesheets and
reads computed flex `order`, so a CSS reorder that draws the chevron before
the status or duration (what the carry's last head did) fails. Red on the
carry's row sources (2 fail), green on base's.
