+# Pool Hub – Task Breakdown
+
+## Status (2025-09-27)
+
+- **Stage 1**: Service still in design phase. Coordinator API and miner telemetry improvements will feed into pool hub scoring once implementation starts.
+
+## Stage 1 (MVP)
+
+- **Project Setup**
+  - Initialize FastAPI project under `apps/pool-hub/src/app/` with `main.py`, `deps.py`, `registry.py`, `scoring.py`, and router modules (`miners.py`, `match.py`, `admin.py`, `health.py`).
+  - Add `.env.example` defining bind host/port, DB DSN, Redis URL, coordinator shared secret, session TTLs.
+  - Configure dependencies: FastAPI, uvicorn, pydantic-settings, SQLAlchemy/SQLModel, psycopg (or sqlite), redis, prometheus-client.
+
+- **Data Layer**
+  - Implement PostgreSQL schema for miners, miner status, feedback, price overrides as outlined in bootstrap doc.
+  - Provide migrations or DDL scripts under `apps/pool-hub/migrations/`.
+
+- **Registry & Scoring**
+  - Build in-memory registry (with optional Redis backing) storing miner capabilities, health, and pricing.
+  - Implement scoring function weighing capability fit, price, latency, trust, and load.
+
+- **API Endpoints**
+  - `POST /v1/miners/register` exchanging API key for session token, storing capability profile.
+  - `POST /v1/miners/update` and `WS /v1/miners/heartbeat` for status updates.
+  - `POST /v1/match` returning top K candidates for coordinator requests with explain string.
+  - `POST /v1/feedback` to adjust trust and metrics.
+  - `GET /v1/health` and `GET /v1/metrics` for observability.
+  - Optional admin listing endpoint guarded by shared secret.
+
+- **Rate Limiting & Security**
+  - Enforce coordinator shared secret on `/v1/match`.
+  - Add rate limits to registration and match endpoints.
+  - Consider IP allowlist and TLS termination guidance.
+
+- **Testing & Tooling**
+  - Unit tests for scoring module, registry updates, and feedback adjustments.
+  - Integration test simulating miners registering, updating, and matching.
+  - Provide CLI scripts to seed mock miners for development.
+
+## Stage 2+
+
+- Introduce WebSocket streaming of match suggestions and commands.
+- Add redis-based lease management, multi-region routing, and attested capability manifests.
+- Integrate marketplace pricing data and blockchain settlement hooks.
