# Implementation Summary: 3 New Features

## Completed Features

### 1. Cascade Router Integration ✅

**Files Created:**
- `src/timmy/cascade_adapter.py` - Adapter between Timmy and Cascade Router
- `src/dashboard/routes/router.py` - Dashboard routes for router status
- `src/dashboard/templates/router_status.html` - Router status UI

**Files Modified:**
- `src/dashboard/app.py` - Registered router routes
- `src/dashboard/templates/base.html` - Added ROUTER nav link

**Usage:**
```python
from timmy.cascade_adapter import get_cascade_adapter
adapter = get_cascade_adapter()
response = await adapter.chat("Hello")
print(f"Response: {response.content}")
print(f"Provider: {response.provider_used}")
```

**Dashboard:** `/router/status`

---

### 2. Self-Upgrade Approval Queue ✅

**Files Created:**
- `src/upgrades/models.py` - Database models for upgrades table
- `src/upgrades/queue.py` - Queue management logic
- `src/dashboard/routes/upgrades.py` - Dashboard routes
- `src/dashboard/templates/upgrade_queue.html` - Queue UI

**Files Modified:**
- `src/dashboard/app.py` - Registered upgrade routes
- `src/dashboard/templates/base.html` - Added UPGRADES nav link

**Usage:**
```python
from upgrades.queue import UpgradeQueue

# Propose upgrade
upgrade = UpgradeQueue.propose(
    branch_name="self-modify/fix-bug",
    description="Fix bug in task assignment",
    files_changed=["src/swarm/coordinator.py"],
    diff_preview="@@ -123,7 +123,7 @@...",
)

# Approve
UpgradeQueue.approve(upgrade.id)

# Apply (runs tests, merges to main)
success, message = UpgradeQueue.apply(upgrade.id)
```

**Dashboard:** `/self-modify/queue`

---

### 3. Real-Time Activity Feed ✅

**Files Created:**
- `src/events/broadcaster.py` - Bridge event_log → WebSocket

**Files Modified:**
- `src/swarm/event_log.py` - Added broadcast call
- `src/ws_manager/handler.py` - Added `broadcast_json()` method
- `src/dashboard/templates/swarm_live.html` - Added activity feed panel

**Architecture:**
```
Event Occurs → log_event() → SQLite
                    ↓
             event_broadcaster.broadcast_sync()
                    ↓
             ws_manager.broadcast_json()
                    ↓
             Dashboard (WebSocket)
```

**Dashboard:** `/swarm/live` (activity feed panel)

---

## Test Results

**Unit Tests:** 101 passed
```
tests/test_event_log.py       25 passed
tests/test_ledger.py          18 passed  
tests/test_vector_store.py    11 passed
tests/test_swarm.py           29 passed
tests/test_dashboard.py       18 passed
```

**E2E Tests:** Created (3 new test files)
- `tests/functional/test_cascade_router_e2e.py`
- `tests/functional/test_upgrade_queue_e2e.py`
- `tests/functional/test_activity_feed_e2e.py`

---

## Running E2E Tests (Non-Headless)

Watch the browser execute tests in real-time:

```bash
# 1. Start the server
cd /Users/apayne/Timmy-time-dashboard
source .venv/bin/activate
make dev

# 2. In another terminal, run E2E tests
source .venv/bin/activate
SELENIUM_UI=1 pytest tests/functional/test_cascade_router_e2e.py -v --headed

# Or run all E2E tests
SELENIUM_UI=1 pytest tests/functional/ -v --headed
```

The `--headed` flag runs Chrome in visible mode so you can watch.

---

## Database Schema Updates

Three new tables created automatically:

```sql
-- Event Log (existing, now with broadcast)
CREATE TABLE event_log (...);

-- Lightning Ledger (existing)
CREATE TABLE ledger (...);

-- Vector Store (existing)
CREATE TABLE memory_entries (...);

-- NEW: Upgrade Queue
CREATE TABLE upgrades (
    id TEXT PRIMARY KEY,
    status TEXT NOT NULL,
    proposed_at TEXT NOT NULL,
    branch_name TEXT NOT NULL,
    description TEXT NOT NULL,
    files_changed TEXT,
    diff_preview TEXT,
    test_passed INTEGER DEFAULT 0,
    test_output TEXT,
    error_message TEXT,
    approved_by TEXT
);
```

---

## Navigation Updates

New nav links in dashboard header:
- **EVENTS** → `/swarm/events`
- **LEDGER** → `/lightning/ledger`
- **MEMORY** → `/memory`
- **ROUTER** → `/router/status`
- **UPGRADES** → `/self-modify/queue`

---

## Architecture Alignment

All 3 features follow existing patterns:
- **Singleton pattern** for services (cascade_adapter, event_broadcaster)
- **SQLite persistence** through consistent DB access pattern
- **Dashboard routes** following existing route structure
- **Jinja2 templates** extending base.html
- **Event-driven** using existing event log infrastructure
- **WebSocket** using existing ws_manager

---

## Security Considerations

| Feature | Risk | Mitigation |
|---------|------|------------|
| Cascade Router | API key exposure | Uses existing config system |
| Upgrade Queue | Unauthorized changes | Human approval required |
| Activity Feed | Data leak | Events sanitized before broadcast |

---

## Next Steps

1. Run E2E tests with `SELENIUM_UI=1 pytest tests/functional/ -v --headed`
2. Manually test each dashboard page
3. Verify WebSocket real-time updates in `/swarm/live`
4. Test upgrade queue workflow end-to-end
