Leo 2026-10-20: the session hover card was a scrolling "History" of truncated prompts and "claude-sr2 finished" lines, with mushy styling and an awkward inner scroll. He asked for it to be "more useful, no scroll, crisp", with ChatGPT's session card as the floor.

The compact layout is now the default, reworked:

• First line: the title (at most two lines), its kind or machine icon, the relative age, and an unread dot in the accent color.
• Status: the status line with how long it has held ("Working 4m").
• Facts: why it waits or its task, then folder, branch, pull request, ports and machine.
• Last message: the agent's last message, up to three lines, rendered from markdown. Bold, italic and code use the card's fonts. Headings, quotes, list marks and code fences are dropped, so the raw marks never show.
• Recent moments: the last three, one line each, with no header and no scroller. The list is as tall as its lines, so the card has a fixed shape.
• Look: glass and theme colors are unchanged (the shared hover-card overlay).

The timeline, log, classic and minimal layouts are still in Settings (sidebar.hoverCards.layout). The settings sources are regenerated. settings-schema.json, docs/mdm/* and the defaults snapshot are left to the autofix.

Follow-ups:

• Tint the machine glyph with MachineColor once cmux-next: machine identity: each machine's color on rows, tabs, chip and palette #22763 lands.
• Token counts. SidebarWorkspace has no token count yet.

Test: WorkspaceHoverCardSummaryTests (commit 5307c72, failing first) covers three things: compact is the default; the card has the unread dot, age, folder, branch and PR, the rendered last message in three lines and three moments; the card never scrolls, is under 360 pt tall and has no raw markdown marks. The timeline tests now ask for .timeline explicitly.

Observed / Not run

• Observed: gen-settings-sources.py regenerated the two hover-card Swift files. prepush-gate.py reported no new violations.
• Not run: no Swift build or tests on this Mac (the rules forbid it). The red-then-green of WorkspaceHoverCardSummaryTests comes from CI on the two commits. No screenshot yet.

Changelog

Changed: The sidebar's workspace hover card is now a compact summary (status, folder, branch, PR, the last message rendered, the last three moments) that never scrolls.

Landing (orphan-sweep, 2026-10-22)

Adopted from its dead owner. Merged base three times (one conflict each in WorkspaceHoverCardTimelineView.swift, base's by-frame layout, and in WorkspaceHoverCardContent.swift, base #24059's Fact.machine beside this PR's Fact.markdown). Lander commits:

• The compact card keeps base cmux-next sidebar: a workspace's hover card says what its agents did since you looked #23510's "Since you looked" line, and its unread dot is Palette.notificationBlue (the sidebar's unread colour; the default theme's accent is grey).
• The unread dot's baseline makes no super call (crash-class selector gate), and it sits on the title's capitals like base's hover card icons.
• From the Codex review: settings and scroll tests now expect the compact default (the long-history scroll test asks for .timeline), a list that does not scroll resets its clip view, the layout fallback reads WorkspaceHoverCardOptions(), and bold code stays monospaced.
• Settings exports (MDM docs, settings-schema.json, defaults snapshot, source stamp) are the PR autofix's Mac regeneration, applied as it came.

Not changed here: the timeline, log, classic and minimal layouts stay in Settings (sidebar.hoverCards.layout).

Capture: the sidebar session cards in the hover-card gallery (debug.hover_cards, the first steps of tour:hover-card). The tour's last step (workspace.showResources) cannot open on a capture mini, so it was left out.

Review (codex gpt-6.1-sol xhigh, correctness first): SHIP at de7eaa0

The diff from 4a0c6246 is exactly one added comment at WorkspaceHoverCard.swift:626. The comment matches check-overlay-glass.py's required glass-opaque-allow syntax and is immediately above the flagged assignment. The filled, corner-rounded 6 pt view is an unread indicator in the title row, not a card surface or background over the shared glass, so the exemption is honest. No other changes are present.

Earlier rounds by the same independent Codex reviewer (acpmux osr-review-22739 on big-red, read-only against git objects):

• BLOCK at 6eefb23: tests still expected the timeline default, the long-history scroll test ran on the compact card, the settings exports were stale, and the history's clip view kept its offset when switching to compact. All fixed in 4ffa79af and 4a0c624.
• SHIP at 4a0c624: diff against base d8de42c is exactly 19 hover-card files (13 implementation/test/source/design plus 6 exports); cmux NEXT Settings: Web UI card shows the served version and rolls back #22889 and other base work preserved; Fact.machine and Fact.markdown both kept; source, generated Swift, schema, defaults snapshot and MDM exports all say compact, and all 284 source-stamp entries match.

Non-blocking follow-ups the reviewer noted and the lander fixed: the .timeline fallback in HoverCardSettings+Options.swift, and bold code losing its monospaced font.

Evidence at the PR's heads: fleet package tests at 4a0c624, step 4b34ae461f143be6ab9619c6 (aws-m4pro-3), passed: WorkspaceHoverCardSummaryTests, WorkspaceHoverCardTimelineTests, WorkspaceHoverCardScrollTests, SidebarSinceLookedTests, HoverCardThinScrollerTests, WorkspaceHoverCardIconLineTests, HoverCardContentSettingsTests, SettingsSchemaExportTests. CI's cmux-next app compile (build fleet) passed at 4a0c624. Capture at 4a0c624 is in the PR body.

Review (codex gpt-6.1-sol xhigh, correctness first): SHIP at 1e789a4

• git diff 740e58fa 1e789a4f matches the previously reviewed d8de42c0..de7eaa02 patch exactly: 19 files, identical additions and deletions.
• The compact hover-card defaults and exports remain present.
• All 284 source-stamp entries match the exact merged tree; no missing or extra inputs remain.
• The inherited cmux NEXT: cmux Classic Mode opens a terminal for Cmd-N and new windows too #23844 settings drift is repaired, including the tabs.terminalFirst exports and hashes.
• No intervening base change touches the PR's hover-card paths or introduces an interaction affecting its behavior.

(Same independent Codex reviewer as the receipt at de7eaa0. eb5d295 was a GitHub update-branch merge; the reviewer's BLOCK there was the base's own stale settings exports from #23844, identical on base 2da204f and repaired by base autofix 740e58f, which 1e789a4 merges in. Fleet ActionRunCreatedTests at de7eaa0 (step 6a77ccdc0cce8117cac080cb) and at base 5526377 (step f7bc9f05fd8653262deb5dc9) both pass, in 1.07 s; CI's red on that test at de7eaa0 was its 2 s wall-clock bound on a loaded runner.)

Superseded by #24785, which now owns the workspace hover surface with the inner-tab popover as the default. Closing this orphaned lane PR; its compact workspace-hover behavior is no longer the active direction.
