The right sidebar's mode (rail | list | graph) is now shared state: a
new useTreePanelMode() hook lets every sidebar section collapse and
expand together. With sub-agents running in rail mode the fleet shows a
quiet strip — bot icon (click expands the sidebar) + vertical 'N running'
count — mirroring the plan rail's node-count strip below it. The sidebar
now collapses all the way regardless of running jobs.
End-to-end verified through the real flow (dispatch part in the
transcript + running job record, the 1s jobs poll rendering the panel):
rail column exactly w-10 with both rails stacked and aligned (40px), the
fleet rail's expand click transitions to list mode and persists, fleet +
plan panels equal widths in list (256/256) and graph (384/384) modes,
9-node graph intact, console clean.
The sub-agents fleet panel was a w-64 fixed aside with no left edge —
aligned with the plan panel only by coincidence in list mode, floating
detached in rail (w-10) and graph (w-96) modes. It now stretches to the
sidebar column's current width and shares the panel's border-l, so the
sidebar is one continuous panel with SUB-AGENTS above PLAN (thin border-b
divider). Verified headlessly in list and graph mode: identical edges and
widths (256/256 and 384/384), perfect vertical stack (fleet 0..99.5, tree
99.5..800), no overlap, 9-node graph intact.
The rail-mode-while-jobs-run question (fleet cards would cram into w-10)
is logged as wave-2 UX design work for the UI stream.
The pi-style ack protocol (previous commit) left the client describing the
old world: artifact cards read the ack string as a result ("could not be
displayed"), the only job poller rendered on input-available parts that no
longer exist (so wake turns landed invisibly until re-navigation), steers
rendered as learner bubbles with no SVG anywhere, and server-persisted
assistant messages carried empty SDK ids (duplicate React keys).
- persistTurn (turn-service): fill empty message ids at the canonical write
— server-only messages (last turn's, wake turns') now key uniquely;
client-authored ids untouched.
- chat.tsx: ONE central /api/jobs poll (fast while jobs run, slow discovery
cadence, off for job-less sessions) drives every job surface, re-syncs
once when a job settles (the record already holds the steer + wake
response at flip time), and adopts server-side wake turns via the same
turnInFlight machinery as returning mid-turn. Steers branch to the
artifact card — never a bubble. Composer no longer gates on jobs.
- /api/jobs now reports turnInFlight alongside the job list.
- dispatch-card: the tool-call box — live activity by toolCallId while
running, quiet "delivered"/"failed" one-liner after; the ack is visible
observability, the artifact lives in the steer.
- steer-card: renders the delivered artifact by kind (research brief /
sanitized SVG / sandboxed demo iframe) from the data-subagent-artifact
part; result renderers extracted and exported from the artifact cards.
- sub-agents-panel: right-sidebar section above the plan tree listing
running sub-agents (kind, elapsed, live activity) — vanishes when idle.
- tests: dispatch/steer/panel render tests re-target the new protocol;
persistTurn id-hygiene suite. 229/229 green, build green.
Out-of-lane touches for master review: chat.tsx + components/** (cleared
this wave), app/api/jobs/route.ts, src/server/turn-service.ts, contracts
protocol doc §2. Live-verified on :3003 (full loop, SSR DOM checked).
