**Endpoint:** `GET /system/state`
**Status:** Complete ✅
**Date:** 2026-04-26

---

## What's Live

### API Endpoints

| Endpoint | Response | Status |
|----------|----------|--------|
| `GET /system/state` | HTML dashboard with HTMX polling | ✅ 200 |
| `GET /system/state?format=json` | JSON schema | ✅ 200 |
| `GET /static/system-state.css` | Stylesheet | ✅ 200 |

### Files Added/Modified

**API (`core/api.py`):**
- Added `system_state()` endpoint (lines ~160-240)
- Added Jinja2 template rendering
- Added static file serving (`/static/`)
- Added custom `format_time` filter

**Templates (`templates/`):**
- `base.html.j2` — Base template with HTMX, CSS links
- `system-state.html.j2` — Dashboard (from Daedalus' handoff)

**Static (`static/`):**
- `system-state.css` — Bar charts, member colors, layout (from Daedalus)

}
```

### HTML Dashboard Sections

1. **Header** — Family name, member count, rule count
2. **Stats Row** — Total docs, auto-routed %, asked-user %
3. **Members** — Color-coded avatars, grade/teacher, docs routed, confidence bars
4. **Active Rules** — ID, description, regex pattern, target members, trigger count
5. **Confidence Distribution** — CSS bar chart (high/medium/low)
6. **Recent Routing Decisions** — Last 10 with status icons

**HTMX Polling:** `hx-trigger="load, every 30s"`

## TODOs for Production

### Telemetry (High Priority)
- [ ] Wire `documents_routed` to actual ingress spooler counts
- [ ] Wire `avg_confidence` to LLM confidence scores
- [ ] Wire `auto_routed` / `user_asked` counters
- [ ] Wire `last_triggered` timestamps per rule
- [ ] Wire `trigger_count` per rule

### Routing Decisions (High Priority)
- [ ] Connect to ingress spooler decision log
- [ ] Store last N decisions in SQLite
- [ ] Add decision status (auto/asked/error)

### Performance (Medium Priority)
- [ ] Cache family config (reload on file change)
- [ ] Cache telemetry (30s TTL)
- [ ] Add request timing metrics

### Security (Medium Priority)
- [ ] Add auth middleware (API key or session)
- [ ] Rate limiting on polling endpoint
- [ ] Audit log for dashboard access

## Design Compliance

**✅ Contract-First:** API spec written first, UI built against it
**✅ Read-Only:** No forms, no mutations
**✅ HTMX Polling:** 30s auto-refresh
**✅ Zero Frontend Code:** Daedalus owns CSS/templates, Socrates owns data
**✅ Family Colors:** blue/pink/purple/green from hoffmann.yaml

---

## Testing

```bash
# JSON
curl http://localhost:8000/system/state?format=json

# HTML
curl http://localhost:8000/system/state

# CSS
curl http://localhost:8000/static/system-state.css
```

**Test results:** All passing ✅

---

## Next Steps

1. **Telemetry wiring** — Connect to ingress spooler when Phase 4 is complete
2. **Auth** — Add CF Access headers or API key middleware
3. **Performance** — Add caching layer for family config
4. **Real data** — Replace placeholders with actual metrics

---

**Handoff:** Ready for Daedalus review. CSS and templates are in his domain if tweaks needed.
