Turn the read-only status page into an auto-updating visual map of the
agent-team DAG (INTAKE -> CLARIFY <-> gate -> PLAN <-> REVIEW ->
[BUILD -> VERIFY -> DISPATCH] -> DONE), rendered as hand-rolled inline
SVG (no CDN/D3 — the R720 is offline/LAN-only).
- Stage model (STAGES) with per-node model/agent role labels (Claude/
GPT-4.1/Gemini/DeepSeek/Slack owner) and gated/role-node flags.
- Per-stage live state (idle/active/awaiting-human/parked) + count badge,
grouped by current_phase; awaiting-human = OPEN pending_question.
- GET /api/state JSON sidecar (snapshot_to_dict); inline vanilla-JS poller
fetches it every 4s and repaints node states/counts/cards/clock/tooltip
in place (no reload, hover/scroll survive). <noscript> meta-refresh
fallback retained.
- Hover/focus tooltip per node: short_id, description, status, waiting age.
- Existing table view kept as a detail section below the map.
- Read-only (mode=ro), fail-safe, no secrets; descriptions escaped for both
HTML and the JSON-in-script seed (< / > -> \uXXXX), DOM via textContent.
