# Web UI

Two web surfaces share the same skeleton: the dashboard (port 7000)
and the per-agent UIs (manager on :8000, sub-agents on a hashed
:8100-8999). Both are SPAs — `GET /` returns a static shell,
`/api/state` returns JSON, JS renders. No full-page reloads.

## Shape (shared by both)

- `GET /` → `assets/index.html` (placeholders for state-driven
  sections, shipped via `include_str!` so the binary has no runtime
  file dependency).
- `GET /static/*.css` + `GET /static/*.js` → static assets.
- `GET /api/state` → JSON snapshot the JS app renders into the DOM.
- `GET /events/stream` (per-agent) / `GET /messages/stream`
  (dashboard) → `text/event-stream` SSE for live updates.

The JS app handles all `form[data-async]` submissions via a delegated
listener: read `data-confirm`, swap the button to a spinner, POST
`application/x-www-form-urlencoded`, re-enable the button on success
(refreshState may keep the form mounted, so we don't rely on a
re-render), call `refreshState()`. State shapes live in
`dashboard.rs::StateSnapshot` and `web_ui.rs::StateSnapshot` —
when adding state fields, plumb through the snapshot struct and the
relevant `assets/app.js` render function.

## Dashboard sections (top to bottom)

1. **C0NTAINERS** — live containers with their action surface.
2. **K3PT ST4T3** — destroyed-but-state-kept tombstones (size +
   age + claude-creds badge). Two actions: `⊕ R3V1V3` (queues a
   Spawn approval; existing state is reused), `PURG3` (wipes
   state + applied dirs; `POST /purge-tombstone/{name}`).
3. **M1ND H4S QU3STI0NS** — pending `ask_operator` questions
   (amber pulsing border). Always renders a free-text fallback
   alongside any option list; `multi=true` renders options as
   checkboxes; submit merges selections + free text comma-joined.
4. **0PER4T0R 1NB0X** — recent messages addressed to `operator`
   (last 50, from the broker).
5. **P3NDING APPR0VALS** — the queue. The R3QU3ST SP4WN form
   lives at the top of this section since submitting it immediately
   queues an approval that lands directly below.
6. **MESS4GE FL0W** — live broker SSE tail.

### Container row

Two-line layout (`assets/app.js::renderContainers`):

- Line 1: agent name (link → new tab), m1nd/ag3nt chip, `needs
  login` / `needs update` warning badges, in-flight `◐ pending-state…`
  pill (replaces buttons during start/stop/restart/rebuild/destroy),
  container name + port.
- Line 2: action buttons — `↻ R3BU1LD` always, `DESTR0Y` + `PURG3`
  on sub-agents, `↺ R3ST4RT` + (sub-agents) `■ ST0P` when running,
  `▶ ST4RT` when stopped. Buttons dim + disable while a transient
  lifecycle action is in flight.

`↻ UPD4TE 4LL` button appears above the containers list when any
agent is stale.

Banner pulses on each broker SSE event (`pulseBanner` with a 4 s
grace timer).

### Dashboard endpoints

- `POST /{approve,deny}/{id}` — approve/deny a pending approval.
- `POST /{rebuild,kill,restart,start,destroy}/{name}` — lifecycle.
- `POST /purge-tombstone/{name}` — wipe a tombstone's state dirs.
- `POST /answer-question/{id}` — answer a pending operator question.
- `POST /request-spawn` — queue a Spawn approval.
- `POST /update-all` — rebuild every stale container.

## Per-agent page

Layout, top to bottom:

- Banner (gradient shimmer while state=thinking).
- Title with `↻ R3BU1LD` button.
- Status section (online / needs login / login-in-progress).
- State badge row (`💤 idle / 🧠 thinking / ○ offline · <age>`) +
  `■ cancel turn` button visible while state=thinking.
- Terminal-wrap: live event tail (with sticky-bottom auto-scroll
  and a `↓ N new` pill when not at bottom) followed by an
  operator-input textarea acting as a prompt.

### Live view

Each agent runs an `events::Bus`: a `tokio::sync::broadcast<LiveEvent>`
plus a sqlite-backed history at `/state/hyperhive-events.sqlite`.
The harness emits `TurnStart { from, body, unread }`,
`Stream(value)` (one per parsed stream-json line), `Note`,
`TurnEnd { ok, note }`. The web UI:

- fetches `GET /events/history` on page load and replays the last
  2000 events (oldest first, with `.no-anim` so they don't stagger);
- then subscribes to `GET /events/stream` (SSE) for live tail;
- shows a granular state badge above the terminal, driven from
  `turn_start`/`turn_end`, with a flash animation on transition;
- sticky-bottom auto-scroll: scrolling up parks the view; new rows
  surface a "↓ N new" pill instead of yanking;
- terminal-themed: phosphor mauve glow, Crust bg, backdrop-filter
  blur, row fade-in slide-up.

Per-stream rendering:

- `Stream` `tool_use` → `→ Read /path` / `→ Bash $ cmd` / `→ send →
  operator: "..."` etc., per-tool pretty rather than raw JSON.
- `Stream` `tool_result` short → flat `← ...`; long → collapsed
  `<details>` `▸ ← Nl · headline` (click to expand full body).
- `Stream` `thinking` → text content if claude provided one,
  otherwise the bare `· thinking …` indicator.
- `Stream` `system init`, `result`, `rate_limit_event` are dropped
  — too noisy.
- `Note` → `· text`.
- `TurnEnd` → `✓ turn ok` / `✗ turn fail — note`, triggers a
  `refreshState()`.

### Terminal-embedded prompt

The operator input lives *inside* the terminal-wrap as a
prompt-style textarea below the live tail: multi-line (Enter sends,
Shift+Enter newlines), tab-completes slash commands.

Slash commands today:

- `/help` — list commands locally
- `/clear` — wipe the local terminal view (server history kept)
- `/cancel` — `POST /api/cancel` → host shellouts `pkill -INT
  claude`, emits a Note. Also surfaces as a `■ cancel turn` button
  in the state row while state=thinking.
- `/compact` — `POST /api/compact` → host spawns
  `turn::compact_session` in the background; output streams into
  the live panel.

Unknown `/foo` shows an error row instead of being silently sent.

### Per-agent endpoints

- `POST /send` — operator-injected message into this agent's inbox.
- `POST /login/{start,code,cancel}` — claude OAuth login flow.
- `POST /api/cancel` — SIGINT the in-flight claude turn.
- `POST /api/compact` — run `/compact` on the persistent session.
- `GET /events/history` — replay buffer for the terminal.
