Carries #27886 (its owner's lane VM no longer resolves). It keeps that PR's commits and authorship, merges the current base, and fixes the conflicts against base's newer tray design.

Takes back #28164: replaces its whole-list progress dependency in App.tsx with keyed AgentProgressStore subscriptions, so a usage-only update notifies only the changed agent instead of rebuilding every row.

Leo, 2026-10-29: "i also want all those ui fixes/improvements in and stuff too along with more think tanks to improve stuff too after learning all those ui dev things".

What it does

• Running workflows show their completed/started agent counts, failed and queued agents in the default running tray and in Session Info. Before, only the alternate transcript card showed them.
• Progress updates arrive through keyed per-agent subscriptions (subagents/agentProgressSource.ts, agentProgressStore.tsx). A usage-only snapshot touches one row and rebuilds no list. Compatibility snapshots, versioned snapshots and session switches keep their progress.
• SW-04: when the owning root is identified late, its progress identity and pending delta are dropped, and real workers and grandchildren stay.
• The Inspector's row and its hover card read the same live progress.

Changes in this carry (base merge)

• Subagent rows: no fork glyph, no tokens or tool uses #29608 took tokens and tool uses off the tray's subagent rows (Leo, 2026-10-31: "we can remove the symbols and the tokens"). The live store follows it: useAgentProgress takes the same usage option, the tray's AgentLine passes progressUsage={false}, and the Inspector keeps its tokens.
• Running tray: Stop inside its line, one chevron column, the header's time after its counts #29264 set the tray's trailing tracks (time, state, Stop's track, chevron), and this carry keeps them. fix(agent-pane): show workflow progress in tray and inspector #27886's own reordering of those columns is dropped, along with its screenshots, which predate both.
• The Inspector's AgentLine gets progressAgent too. Before this, only its hover card subscribed to live progress, so inspector-subagent-card-stays failed: the line kept "0/3 agents · 1K tokens".
• The tests follow the tray's counts, with no tokens.

Observed / Not run

• Local: bun test test/subagent-tray.test.tsx test/agent-pane-workflow-progress.test.tsx test/inspector-subagent-card-stays.test.tsx test/subagent-tray-trailing.test.ts passes (47 pass, 0 fail). bun run check is clean.
• Not run locally: the Chromium tray geometry suite, which goes to CI at this head.
• No screenshots: Leo tries the build.

Changelog

• Fixed: running workflows show their agent counts in the running tray and in Session Info.

Design: running tray.

Summary by cubic

Shows running workflow progress (completed/started counts, failed, queued) in the default running tray, the Inspector's row, and their hover cards. Replaces the whole-list progress dependency in App.tsx with keyed per-agent AgentProgressStore subscriptions, so usage-only updates re-render just the changed agent row instead of rebuilding every row.

• Direct snapshots carry keyed progress deltas from the event fold; bridge/gallery snapshots keep the same keyed contract, with a compatibility path for unversioned snapshots, and reset their store per session.
• A late root identification drops phantom progress while real workers and grandchildren stay.
• Since the base merge, no subagent list shows tokens or tool uses (only the Inspector's Context does); the tray and Inspector rows read the same live store.

Observed / Not run

• Local: bun test test/subagent-tray.test.tsx test/agent-pane-workflow-progress.test.tsx test/session-info-subagent-card-stays.test.tsx test/subagent-tray-trailing.test.ts passes (47 pass, 0 fail). bun run check is clean.
• The App tests turn workflows off as the workflowLabs push would (base turns them on by default, cmux NEXT: Claude workflows show by default, not behind Labs #30192) and open the tray for their chats (perf(agent-pane): skip 300 hidden row elements in folded running tray (SW-04) #29250), since a running workflow leaves the tray.
• Not run locally: the Chromium tray geometry suite, which goes to CI at this head.
• No screenshots: Leo tries the build.

Review (codex-review-box/gpt-6-astra high, lane-place): SHIP at fcb542e

SHIP at fcb542e

Visual verdict: no images; Leo tries the build

1. [P2] [follow-up] webviews/src/agent-session/acpmux/App.tsx:7453 — Bridge deltas can be lost when React batches snapshots. If an update for agent A is followed by another snapshot before rendering, only the latter delta reaches this effect, leaving A’s progress stale. Apply deltas when received or accumulate them before rendering. Add coverage for consecutive receives without an intervening render.
2. [P2] [follow-up] review/pr.body:25 — No after screenshots were supplied; tray and Inspector appearance remain visually unverified.

Validation: all 13 changed files passed syntax parsing; isolated progress-store checks passed. React tests could not run because Bun and dependencies are unavailable.

Follow-ups:

• Preserve bridge progress deltas across batched snapshots.
• Check tray and Inspector visuals in the build.

Review (subagent claude-opus-5-5 medium): SHIP at eba6a78

Delta review covering:

• The base merge 2818041. It is mechanical: base renamed inspector/ to session-info/ (carry #29651: Session Info is called Session Info in its code, not Inspector #29921), and the one hand-resolved hunk keeps this PR's AgentProgressStore import and base's session-info/SubagentsSection path. Nothing from either side was dropped.

• eba6a78, which is test-only. agent-pane-workflow-progress.test.tsx now follows three base changes:

  • Workflows are on by default (cmux NEXT: Claude workflows show by default, not behind Labs #30192), so a workflow leaves the tray. The test turns workflows off through applyWorkflowLabs(false).
  • A folded tray builds no rows (perf(agent-pane): skip 300 hidden row elements in folded running tray (SW-04) #29250). The test opens the tray with rememberTrayOpen.
  • The Session Info aside is now aside.acpmux-session-info.

  Every assertion is unchanged.

Fleet: 96/96 pass across the tray and Session Info suites at eba6a78.

Follow-ups:

• Cover the workflows-on default: a keyed progress update reaching the workflow card and Session Info's Background tasks, and late root retirement there.

Review (next-review patch-id; carried): SHIP at cbc4c94

The independent SHIP at eba6a78 carries to this head: the PR's own change (git diff $(git merge-base feat-cmux-next HEAD) HEAD) has the same git patch-id --verbatim (ee268feabd1e5cc2) at both heads, and no merge between them was resolved by hand. Nothing new to review. A newer BLOCK, or any change to the PR's own diff, ends the carry.
