Two small transcript CSS fixes Leo asked for on 2026-10-31.

1. The turn footer sits in the middle of its gap.

Leo: "when i hover this little whatever time ago copy sound ellipsis thing should be centered in between the two things you're saying in between / so padding after == padding before that kinda thing all around"

Before: the footer's 24px line (time, Copy, Read aloud, More) was 7px under the reply's last text line and 16px over the next prompt's bubble. Now the line moves down inside its own row by --cv-footer-drop (4px, or 2px over the same agent's next reply, whose first line has the same half-leading). That amount comes off the row's bottom padding. Room above and below is now about 11px and 12px, and over the composer it is the same. Every footer row keeps its height, so model.ts's estimates still match and the running-turn line the footer replaces doesn't jump.

2. Tables are less faint.

Leo: "at least the left side of our table if we're gonna have it should be more distinctly there it's all almost a bit too faint"

  • Row rules go from 4.5% to 9% of the text colour.
  • Every table's first column, which names its rows, takes the label weight (500). Labeled tables already used it.
  • The header keeps its strong rule.

Test: webviews/test/agent-pane-transcript-spacing.test.ts now measures the room above and below the first and last footer: from the reply's last line box to the footer line, and from the footer line to the next bubble or the composer. It requires the two to be within 1.5px. On base they are 7 and 16.

Risk: CSS only, in conversation.css. No footer or table geometry outside the agent-pane transcript changes; Chief views keep their own .cv-table. Not covered here:

Spec: design/chat-transcript.md (transcript rhythm).

Summary by cubic

Centers the transcript turn footer between the reply's last line and the next row, and makes markdown tables read more distinctly.

  • The footer (time, Copy, Read aloud, More) moves down inside its own row so the room above and below is balanced (~11px/12px). The drop is 4px, 2px over the same agent's next reply, and 0px for the footer that ends the chat, which still rests the turn gap over the composer. Each footer keeps its height, so transcript estimates and the running-turn line don't jump.
  • Table row rules go from 4.5% to 9% of the text color, and the first column takes the label weight (500) in every table, not just labeled ones.

Tests

  • The spacing test measures the room above and below a footer between turns and requires the two to be within 1.5px; before the change they were 7px and 16px.
  • Only the footer with no following row keeps its line over the composer's rest gap; a footer followed by an incoming agent's message still centers.
  • The continuation-spacing test expects the footer's 4px (2px over the same agent) centring drop in the padding measurements, and the chat-ending footer to keep the full turn gap.

Risk: CSS-only in conversation.css; no transcript geometry outside the agent pane changes, and Chief views keep their own table styles.

Written for commit 2ed0d7e. Summary will update on new commits.

… table rows and first column

The turn footer's 24px line (time, Copy, Read aloud, More) sat 7px under the reply's last
line and 16px over the next prompt. It now moves down inside its own row by --cv-footer-drop
(4px; 2px over the same agent's next reply), taken off the row's bottom padding, so the
room above equals the room below and every footer keeps its height.

Markdown tables: row rules go from 4.5% to 9% of the text colour and every table's first
column takes the label weight (500), as a labeled table's already did.

Review (subagent claude-opus-5-5 medium): SHIP at 9f8fc46

Every footer row keeps its total height. The normal and last footers are 4 + 24 + 12 = 40, the same as 0 + 24 + 16 before, and the continuation footer is unchanged too. So model.ts's estimates and the running line the footer replaces still match. There are no specificity or order problems. The new assertion should fail on base (7 vs 16) and pass here (about 11 vs 12). The .cv-table rules stay scoped to conversation.css; Chief views have their own.

Follow-ups:

  • The last-footer padding rule now repeats the base rule and can be removed.
  • The centring tolerance depends on the headless font's half-leading. footerToNextPrompt and lastFooterToComposer now sit at their lower bound of 12.
  • An empty footer's absolutely placed hover controls are not shifted by --cv-footer-drop, as on base.
  • cv-table--labeled detection is now unused by CSS (the class is still emitted and tested).

Review (subagent claude-opus-5-5 medium): SHIP at f925099

The new commit only brings transcript-continuation-spacing.test.ts's expectations in line with the footer drop:

  • Paddings are [6,12,12,12], and [8,16,16,16] with the tokens scaled.
  • The test still guards the token scaling; it was not loosened.

Fast checks at this head pass 98 of 98 tests in 8 files: transcript spacing, turn footer, continuation spacing, table actions and copy, rowEstimates, compaction rows and message placement. run

The conflict was in agent-pane-transcript-spacing.test.ts. #30297 rests the last row REST_GAP (56px)

footer drop moved the last footer too. It has no next row to centre on, so it keeps base's position.

Review (subagent claude-opus-5-5 medium): SHIP at 2ed0d7e

This head merges feat-cmux-next, which brings #30297's REST_GAP. The footer that ends the chat now keeps its line in place over that rest gap: --cv-footer-drop: 0px through .acpmux-row--last-footer:not(:has(~ .acpmux-row)). Every other footer, including one followed by an incoming, queued or pending message, keeps the drop that centres it.

Rows are direct <article class="acpmux-row"> siblings in .acpmux-thread, ordered by chat order, so the selector reads the chat's order. The footer row's height is unchanged both ways (4+24+12 over a next row, 0+24+16 at the chat's end), so the model.ts estimates and #30297's running line still hold.

The table changes are as before. The test expectations match the CSS.

Follow-ups:

  • [follow-up] Replace the DOM sibling test with a model-driven class (for example acpmux-row--chat-end when nextDrawnRow is undefined). A trailing row that draws nothing currently gives the end footer the 4px drop, 52 px over the composer instead of 56.
  • [follow-up] footerToNextPrompt now sits at its >= 12 floor. Lower it to 11 so rounding can't flake it.
  • [follow-up] cv-table--labeled no longer has a CSS rule. Drop the class from TableBlock.tsx or note it's kept as a hook.

#29860 centres a turn footer between the reply's last line and the next
prompt by padding the footer row. On the grid the footer has no height and its
action row is laid in the gap, so the resolution keeps the grid footer. A
footer over a prompt now sits in the middle of the turn gap, raised by half the
reply's half-leading. Continuation and last footers stay centred in the block
gap, which restBand assumes. The spacing test keeps the grid measures and
adds #29860's centring check.

#29860 moved the turn footer's line down 4px inside its row (--cv-footer-drop),
taken off its bottom padding, so the footer-to-sender gap is 2px under the turn
gap instead of 2px over it. The gallery play still expected gap + 2.

Both browser tests predate #27580, which moved every outer gap between
transcript rows into the virtual stack (design/grid.md 5.5). The
continuation test still asked for #26755's half gap and #29860's footer
drop inside the row; the fold test counted every placed gap, and the
row's own gap target, as blank space. Both now take their values from
the grid tokens (gridLength).
