-### Rust standalone binary (`notiflo-runtime`)
-1. **Ingest connectors** — WebSocket (tokio-tungstenite), Kafka (rdkafka), Redis queue (redis crate)
-2. **Delivery layer** — async HTTP client (reqwest) for provider APIs, retry with backoff, dead letter to Redis stream
-3. **Event log** — writes delivery events to Redis streams for NestJS to consume
-4. **Config loader** — reads alert conditions from MongoDB or Redis, watches for changes

-### NestJS changes
-- Config push: write alert configs to Redis/MongoDB for Rust binary to read
-- Dashboard: consume delivery events from Redis streams
+## What's Built (Core Pipeline)
+
+### Rust standalone binary (`notiflo-runtime`) — COMPLETE
+1. **Ingest connectors** — Redis Stream ingest with per-connector tasks, hot-reloaded from MongoDB every 5s
+2. **Delivery layer** — InAppProvider (0μs, no HTTP) + HttpProvider (reqwest, retry with backoff, dead letter queue)
+3. **Event log** — Redis Streams writer (`notiflo:events:delivery`) with rendered_content for in-app
+4. **Config loader** — reads alert conditions + connectors from MongoDB, periodic refresh
+5. **Pipeline instrumentation** — lock-free atomics for eval latency, delivery latency, throughput
+6. **Health endpoint** — `/health` exposes all metrics (avg/max eval latency, throughput tps, delivery count)
+7. **Subscriber cache** — DashMap backed by MongoDB with auto-detect from available contact data
+
+### NestJS — COMPLETE
+- **Connectors module** — CRUD for Redis Stream connectors
+- **Redis Stream consumer** — consumes delivery events, persists to MongoDB
+- **WebSocket gateway** — standalone `ws.Server` on `/ws/notifications` (Fastify-compatible, no WsAdapter)
+- **Metrics bridge** — polls Rust `/health` every 5s, broadcasts via WebSocket
+
+### Next.js Dashboard — COMPLETE
+- **Pipeline Performance** — 8-card grid with live throughput, eval latency, deliveries (via WebSocket)
+- **Notifications feed** — live delivery events with LIVE/OFFLINE indicator
+- **Connectors page** — manage Redis Stream connectors
+- **WebSocket hooks** — `useWebSocket`, `useLiveMetrics`, `useLiveNotifications`
+
+### Docker Compose — COMPLETE
+- Full stack: MongoDB, Redis, Rust runtime, NestJS API, Next.js dashboard, seed data, ticker simulator
+- `docker compose up` starts everything with health checks and proper ordering
 
 ### Design Principles
 - Hot path stays in Rust — never crosses to Node
@@ -154,6 +212,11 @@ npx nx serve notiflo-web   # Start dashboard
 - Node consumes at its own pace, persists to MongoDB
 - Burst-heavy, high-sleep pattern — optimize for the burst
 
+### Known Gotchas
+- **Fastify + WebSocket**: Fastify intercepts HTTP upgrade requests before NestJS WsAdapter. Use standalone `ws.Server` with `noServer: true` and manual `httpServer.on('upgrade', ...)` handler.
+- **Serde empty objects**: `channelPreferences: {}` deserializes as `Some(HashMap::new())`, not `None`. Check `.map_or(false, |p| !p.is_empty())`.
+- **Ticker drift**: Random-walk prices drift away from thresholds over time. Restart ticker with runtime for fresh crossings.
