On the server's /api/v2 (3.4.0, server dev 5d7b79c):
- The activity panel reads GET /chats/{chat}/tree beside the activity and
draws ui/js/tree.js's rows in a Subagents section, the server panel's words
and layout: nested by parent, position, phase, context %, state, model,
mode + request options, messages and the last one, open slots, the ended
ones folded and dimmed. A team's members are no longer drawn again among
the tasks. The stream's `tree` frame redraws it.
- A subagent's conversation (/subagents/{id}/transcript, read again every 3 s
while it works) and its findings open read-only in the panel; Stop asks,
then POSTs /stop. With an agent chat's device away: the kept tree with the
server's note, and its 409 sentence for the rest.
- A new agent chat's Subagents chip from /models?kind=agent&device= (each
model's `subagents`, `agent_subagents.offered` and `device_runs`); an open
agent chat's from its own `subagents`, as before.
- An approval item's `subagent` names it on the card.
- Progress keys are the spec's own ({{field}}), as the server's catalogues
have them; SERVER_PENDING is gone, every sentence is translated.
tests/ui reads the server's contract fixtures (scripts/fetch-fixtures.sh ->
tests/ui/fixtures, SOURCE says the commit): status frames, tree, tree frame,
transcript, findings, models?kind=agent, a subagent's approval; six C4 cases.

ui/js/tree.js draws subagents.md §12's data: the main agent at the root, each
subagent under its parent in the order added (name, id, position, state in
team.read.states' words, model, mode with request options, context % and a
meter, its progress line, its room messages and the last one), open slots, and
the ended ones folded apart, dimmed, with how each ended; open its session,
its findings, stop a live one. Not wired into the activity panel yet: the
server's /api/v2 does not carry the tree, the transcript or the findings yet.
tests/ui: the spec's own example tree, drawn and acted on.
