fix(cmux-next): clarify disclosed workspace tab hierarchy (carries #27128) by teamleaderleo · Pull Request #27530 · manaflow-ai/cmux

teamleaderleo · 2026-10-29T19:36:19Z

Carries #27128 (its commits and authorship unchanged) on top of the current base. Its owner lane is unreachable, so this PR lands it in its place; #27128 gets a comment linking here.

Leo, 2026-10-29: "F***ING JUST DO IT" (the sidebar work is ordered in; the sidebar dogfood HOLD comes off, and the #26809 HOLD only ever covered #26809).

The base merge had one conflict, in plans/cmux-next/sidebar-owner.md (notes only). Both sides were kept.

Aziz reported: “This workspace tabs disclosure is annoying, can't make out workspace from non-workspace easily.”

This PR makes disclosed workspace tabs read as children at a glance while preserving disclosure, defaults, group rails, motion, selection/focus semantics, trailing columns, and all existing tab detail/status/icon behavior. The chosen hierarchy tokens are a 16 pt child title inset (Metrics.space6 via SidebarStyle.tabChildIndent) and the existing caption scale for tab titles/details. Plain tabs use secondary ink; focused, selected, and unread tabs retain primary ink and the existing focused fill.

SidebarWorkspaceTabHierarchyTests covers ungrouped, grouped, and nested workspaces; favicon and no-favicon tabs; focused/unread state; narrow widths; every density and Minimal Mode; exact 16 pt title anchoring; parent icon changes through model patches and full reloads with the parent offscreen; agent-mark setting changes; clipped text width; late parent realization through the page viewport and reuse pool; leading agent/machine marks; trailing alignment; and row reuse. The assertion-first test was committed before the implementation and failed on the base because tab titles did not meet the child inset contract. The implementation is now at this PR head.

Reference: Claude desktop’s sidebar-linked-session-nesting.png for clear parent/child indentation and secondary ink, using our colours and glass. Before/after evidence shows real disclosed workspace tabs in light and dark, built on the fleet and captured on owned capture minis. AATabLinesGalleryTests supplies the native gallery comparisons. The private Aziz screenshot remains private. The native gallery compares indentation-only, typography-only, and the chosen combined treatment at the same 280 × 360 pt viewport. The typography-only fixture restores the full available text width while keeping trailing controls fixed.

The existing row patch and shared tunable watcher invalidate affected child geometry. Status-only patches leave child layout untouched; this adds no timer or observer.

Risk: contained to tab-row title geometry and ink; no layout rows, disclosure state, animation, or interaction semantics change. Existing look, tab switch patch, icon, trailing-column, and tuck tests remain in scope. Swift validation runs through cmux-ci on the fleet; no local build is used.

Summary by cubic

Fixes the disclosed workspace tab hierarchy so disclosed tabs read as children of their workspace at a glance. Carries #27128 onto the current base; its owner lane is unreachable, so this PR lands it in its place and comments on #27128.

Disclosed tab titles sit 16 pt inside the workspace title column and use the caption scale; plain tabs take secondary ink while focused, selected, and unread tabs keep primary ink and the existing focus fill.
Tab anchors follow parent icon and leading-mark changes, including offscreen and late-realized parents; status-only patches no longer invalidate child layout.
SidebarWorkspaceTabHierarchyTests covers ungrouped, grouped, and nested parents, every density and Minimal Mode, narrow widths, favicon and no-favicon tabs, and row reuse.

Behavior is unchanged for disclosure, defaults, group rails, motion, selection/focus semantics, trailing columns, and all existing tab detail/status/icon behavior. Risk is contained to tab-row title geometry and ink.

Workspace rows remain the visual root while disclosed tabs use a 16 pt child inset and quiet secondary typography. Focused, selected, and unread tabs retain primary contrast.

The slice head 2b2fc8e (= 43037147a0b's tree: slice + trunk sync c09bb74) merges the feat tip, 130 new commits. 58 files conflicted: - 0 reuse the previous round's resolutions: this round's base is the previous feat tip a14725a, so no hunk had all three sides equal to 5f39f9e's inputs. - Regenerated, not hand-merged: the 4 CmuxMessagesLab patches (Fixture, Layout, RowDrawing, WindowView) from the merged vendored sources against the pinned upstream reconstructed from the side whose patch was consistent (feat's for 3, perf's for WindowView; feat 65de604 edited WindowView.swift without rewriting its patch). - 54 resolved by porting feat's change into perf's shape: - Package.swift (CmuxNext: Floating tests get CmuxNextDesign with perf's Wakeups deps; CmuxMobileKit: Model gets feat's Resources with perf's CmuxSafeConcurrency). - Lineage parents #24136: SidebarSessionTreeFeed (recordedParents and per-host links on perf's ServiceObservation), RemoteAcpmuxWire (host/linksAlias notes posted on perf's mainWork; test-only inits take them too), AgentTabRemoteHost, AgentTabs+Wiring, AgentSessionWorkspace (the record is one completion task on main), tests. - Artifact sandbox #26216: perf's page-host PageArtifactFrame already serves the sandboxed endpoint; feat's navigation tests ported to PageNavigation, frame-ancestors expectation added, artifactFrameURL keeps only the page host, webviews tests on perf's URLs. - pane.commandAvailability (#25405) and chief.face (#27914) beside perf's keyToPaint and Wiring init. - State files off main #27749: AgentUnsentDrafts (perf's ObservedMap) and ScrollAnchors (blockingDecode) on AgentPaneStateFile. - AgentPaneTransport.close: perf's close reason plus feat's host-request failure and trust reset. - CloudService: perf's file, plus #27104 signedOutCreation (scope, policy, stop, signOut in +Machines) and #26740 autosize/sizePick; listIsCurrent moved to +AppServer as feat did. - debug.object_menu into perf's DebugDriverControl; Home fixture presence/faces beside perf's field. - Palette overlay window #26951 into perf's paletteBuilt. - Per-window Home #27880 in perf's dockTab helper; active team (1bb1b96) on perf's cloudAuth. - Busy refusal (a930474, 2a9b813) in perf's LineTransport split (+State, +Route, framed write). - Launch snapshot sidebar doc (dc38061): DaemonLaunchSnapshot.sidebarDoc, shown once settled (whenSettled), its connect follow a ServiceObservation; the Rust test moved to launch_snapshot_tests.rs. - Hover card corners (bc66475) with perf's interactive flag; Chief pet state (#25671) on perf's ServiceObservation and AppearanceSignals; Chief picture crop (#27933) on perf's lanes and optional store; Home presence (#25578) as a FrameObservation; sidebar tab look (#27530) via SidebarLookFollower; settleOpenings (#24374) with perf's snap; Omnibar imports. - acpmux: inbox digest senders without slicing; withdraw_queued async with from_agents_only; cmux-tui-core and platform: connection leases beside perf's modules and InlineSocket (bounded_outbound.rs takes back the `platform::transport` import perf had dropped, which feat's claim_watched_connection names). - webviews: App/NewTab/NewTabScreen (retry, slash commands, at), settings keys moved to cardRows.ts. - Feat's tests that call perf-changed inits fixed: TabConcentricCornerTests (input:), HomeChatPresenceFacesTests (deadlines:, frame delivery), RemoteChildSessionsTests (main run loop for posted notes). Generators: cargo metadata in cmux-tui, cmux-tui/fuzz, Native/DiffSidecar and optchat-chief changed no lock; gen-features.py --check, gen-chromium-host-wire.py --check and --check-ops, sync-resource-api.py --check pass. webviews: bun run check passes. schemas/settings/settings-schema.json stays perf's (generated; the autofix regenerates it): until then feat's chiefLook.test.tsx misses the home.bubbleColors rows.

Resolves the WorkspaceRowView.configure conflict with #27530: the harness fallback glyph moves into Self.agentMarkImage (so the offscreen title column matches the drawn mark), and the stable fallback colour comes from Self.agentMarkFallbackColor.
