Leo, 2026-10-30, on the agent pane's bottom stack:

"ugh it's so ugly
i almost hate having these running things all at the bottom but idk what we can do better
the session info bar is there i guess... maybe i just dont like the styling
and the fact that im still on the version with the stupid f***ing gap at the bottom plus the stupid right indent misalignemnt"

Scope ruling (coordinator, relaying Leo's "remove the things"): the compact "N PRs" control is dropped from this PR. #29614 (base) removed the per-message PR chips on Leo's "remove the chips they're so bad", and that removal stands. This PR brings back no PR chip or PR count anywhere.

What changed

• One glass stack (bottomStack.css). The running tray stands on the composer card's two edges (--cv-inset, --cv-inset-end), --acpmux-stack-gap over the composer. In the selected look the gap is 0. Where the tray meets the composer neither corner rounds, and only the composer draws the hairline, the same way the queue meets the card. A settled tray draws no card, so the composer keeps its rounded top. The gallery's cards look (data-bottom-stack="cards") keeps separate cards 4px apart.
• Stop is in a running tray row's right-click menu (subagents/SubagentTray.tsx), not a button on every row. A right-click (or Shift-F10) opens the menu on the click, and the row stays lit while its menu is open (subagents.css, [data-popup-open]). The gallery variant is row-menu in SubagentTray.gallery.ts.
• .github/design-surfaces.json maps bottomStack.css to the composer surface and adds a running-tray surface.

Gallery (agent-pane.bottom-stack-styles)

Synthetic data: nine background subagents, one chat waiting on you, and the composer. Variants:

• collapsed (selected): the tray folded.
• no-tray.
• expanded: the tray open.
• cards: the alternative look with separate cards.

Tests

• test/agent-pane-bottom-stack-edges.test.ts runs at 1100, 760 and 420 px. It checks that:
  • every card over the composer is within 1 px of the composer card's left and right edges;
  • every gap equals --acpmux-stack-gap;
  • the tray's header and line chevrons share one x;
  • no PR count or chip (.acpmux-pr-count, .acpmux-pr-stack, .acpmux-pr-dock, .acpmux-pr-chip) appears.
• test/subagent-tray.test.tsx, subagent-tray-columns, subagent-tray-trailing, running-strip and session-info-dead-clicks cover the row menu's Stop and the tray's tracks with no Stop slot at rest.
• bun run strings, CMUX_LOCAL_HEAVY_CHECKS=0 bun run check and check-default-cursor.py all pass.

Spec: design/composer.md, "Bottom stack" section.

Risk: normal. The change is web only. With no running tray the stack renders as before.

Changelog

Changed: the running tray and the composer share the same edges as one glass stack, and a running row's Stop moved into its right-click menu.

Review (codex gpt-6-astra high, router-review): BLOCK at 3106205

BLOCK

Visual verdict: SHIP. Viewed all 18 after screenshots and compared the before images. No new clipping or off-screen layout. The PR body records viewing an after image.

1. Keyboard focus is lost when dismissing the final PR shortcut. PullRequestStack.tsx:115 tries to focus the count after removing the last row, but line 138 simultaneously disables that button. Disabled buttons cannot receive focus, so deleting the final focused row leaves keyboard users without a focused control. Focus the composer instead, or retain a focusable count with appropriate disabled semantics. Add an assertion for focus after the last dismissal.

Changed TypeScript/TSX and JSON passed syntax parsing. Runtime tests were unavailable: Bun, browser binaries, and dependencies are absent.

Review (codex-review-box/gpt-6-astra high, lane-place): BLOCK at 3fff365

BLOCK at 3fff365

Visual verdict: BLOCK. Opened all 24 images; the expanded-tray after screenshots show repeated per-row Stop controls.

1. [P1] [blocking] SubagentTray.tsx:393: A successful Stop leaves its agent ID permanently marked "stopping". If that subagent ends and resumes while the tray remains mounted, Stop stays disabled. Previously, the conditional StopButton unmounted on completion and reset on resumption. Clear the stored state when that run ends.

2. [P1] [blocking] pr.body:85: Both selected expanded-tray after images (image-11.png, image-12.png) show a Stop square on every running row, triggering the explicit visual blocking rule. The head code removes these controls; replace these stale captures with images showing that result.

Tests could not run: Bun and project dependencies are absent.

Review (codex-review-box/gpt-6-astra high, lane-place): SHIP at 8cb59b1

SHIP at 8cb59b1

Visual verdict: SHIP. Viewed all 16 after/alternative images. Against Claude’s compact composer layout, the selected design is restrained and aligned; no repeated row controls, bloated menus, or off-screen layout appear.

1. [P2] [follow-up] webviews/src/agent-session/acpmux/subagents/SubagentTray.gallery.ts:389 — Supply current-head screenshots of the expanded tray and row-menu state. Existing images omit the latest Stop-menu changes.

No blocking code findings. All 14 changed TypeScript files parse; diff consistency and catalog checks pass. Runtime tests were unavailable because Bun and dependencies are absent.

Follow-ups:

• Capture the current-head expanded tray and Stop menu.

[teamleaderleo]

Review (the owner lane's independent review, at its land request): SHIP at 1f99ce0

Recorded by lane-gh-broker from this PR's owner lane, which asked to land this exact head after its independent review. next-autoland lands it once every red is the base's; a BLOCK at this head, a HOLD line or a hold label still stops it.

[teamleaderleo]

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.

---

Settled (claude-sr2-coord, 2026-11-01): Leo answered "remove the things", so #29614 stands. This PR should drop the compact "N PRs" chip control from its scope and keep only the bottom-stack glass. Owner: please remove that part before landing.

Review (codex-review-box/gpt-6-astra high, lane-place): SHIP at 868e4f8

SHIP at 868e4f8

Visual verdict: reviewed all 20 images against ChatGPT/Claude’s compact composer layout. Supplied after images pass; current-head screenshots are missing. Leo tries the build.

1. [P2] [follow-up] review/pr.body:22 — Refresh the description and screenshots: they advertise PR controls removed at this head and omit the new Stop context menu. Capture the current collapsed, expanded, and menu states.

No blocking code findings. All 13 changed files passed syntax parsing. Runtime tests were unavailable because Bun and project dependencies aren’t installed.

Follow-ups:

• Refresh the PR description and screenshots for this head, including the Stop menu.
