chore: refactor logging module, update genesis timestamp, remove model relationships, and reorganize routers - Rename logging.py to logger.py and update import paths in poa.py and main.py - Update devnet genesis timestamp to 1766828620 - Remove SQLModel Relationship declarations from Block, Transaction, and Receipt models - Add SessionDep type alias and get_session dependency in coordinator-api deps - Reorganize coordinator-api routers: replace explorer/registry with exchange, users, marketplace

# Coordinator API – Task Breakdown
|
||
|
||
## Status (2025-12-22)
|
||
|
||
- **Stage 1 delivery**: ✅ **DEPLOYED** - Coordinator API deployed in production behind https://aitbc.bubuit.net/api/
|
||
- FastAPI service running in Incus container on port 8000
|
||
- Health endpoint operational: `/api/v1/health` returns `{"status":"ok","env":"dev"}`
|
||
- nginx proxy configured at `/api/` (so `/api/v1/*` routes to the container service)
|
||
- Explorer API available via nginx at `/api/explorer/*` (backend: `/v1/explorer/*`)
|
||
- Users API available via `/api/v1/users/*` (compat: `/api/users/*` for Exchange)
|
||
- **Testing & tooling**: Pytest suites cover job scheduling, miner flows, and receipt verification; the shared CI script `scripts/ci/run_python_tests.sh` executes these tests in GitHub Actions.
|
||
- **Documentation**: `docs/run.md` and `apps/coordinator-api/README.md` describe configuration for `RECEIPT_SIGNING_KEY_HEX` and `RECEIPT_ATTESTATION_KEY_HEX` plus the receipt history API.
|
||
- **Service APIs**: Implemented specific service endpoints for common GPU workloads (Whisper, Stable Diffusion, LLM inference, FFmpeg, Blender) with typed schemas and validation.
|
||
- **Service Registry**: Created dynamic service registry framework supporting 30+ GPU services across 6 categories (AI/ML, Media Processing, Scientific Computing, Data Analytics, Gaming, Development Tools).
|
||
|
||
## Stage 1 (MVP) - COMPLETED
|
||
|
||
- **Project Setup**
|
||
- ✅ Initialize FastAPI app under `apps/coordinator-api/src/app/` with `main.py`, `config.py`, `deps.py`.
|
||
- ✅ Add `.env.example` covering host/port, database URL, API key lists, rate limit configuration.
|
||
- ✅ Create `pyproject.toml` listing FastAPI, uvicorn, pydantic, SQL driver, httpx, redis (optional).
|
||
|
||
- **Models & Persistence**
|
||
- ✅ Design Pydantic schemas for jobs, miners, constraints, state transitions (`models.py`).
|
||
- ✅ Implement DB layer (`db.py`) using SQLite (or Postgres) with tables for jobs, miners, sessions, worker sessions.
|
||
- ✅ Provide migrations or schema creation script.
|
||
|
||
- **Business Logic**
|
||
- ✅ Implement `queue.py` and `matching.py` for job scheduling.
|
||
- ✅ Create state machine utilities (`states.py`) for job transitions.
|
||
- ✅ Add settlement stubs in `settlement.py` for future token accounting.
|
||
|
||
- **Routers**
|
||
- ✅ Build `/v1/jobs` endpoints (submit, get status, get result, cancel) with idempotency support.
|
||
- ✅ Build `/v1/miners` endpoints (register, heartbeat, poll, result, fail, drain).
|
||
- ✅ Build `/v1/admin` endpoints (stats, job listing, miner listing) with admin auth.
|
||
- ✅ Build `/v1/services` endpoints for specific GPU workloads:
|
||
- `/v1/services/whisper/transcribe` - Audio transcription
|
||
- `/v1/services/stable-diffusion/generate` - Image generation
|
||
- `/v1/services/llm/inference` - Text generation
|
||
- `/v1/services/ffmpeg/transcode` - Video transcoding
|
||
- `/v1/services/blender/render` - 3D rendering
|
||
- ✅ Build `/v1/registry` endpoints for dynamic service management:
|
||
- `/v1/registry/services` - List all available services
|
||
- `/v1/registry/services/{id}` - Get service definition
|
||
- `/v1/registry/services/{id}/schema` - Get JSON schema
|
||
- `/v1/registry/services/{id}/requirements` - Get hardware requirements
|
||
- Optionally add WebSocket endpoints under `ws/` for streaming updates.
|
||
- **Receipts & Attestations**
|
||
- ✅ Persist signed receipts (latest + history), expose `/v1/jobs/{job_id}/receipt(s)` endpoints, and attach optional coordinator attestations when `RECEIPT_ATTESTATION_KEY_HEX` is configured.
|
||
|
||
- **Auth & Rate Limiting**
|
||
- ✅ Implement dependencies in `deps.py` to validate API keys and optional HMAC signatures.
|
||
- ✅ Add rate limiting (e.g., `slowapi`) per key.
|
||
|
||
- **Testing & Examples**
|
||
- ✅ Create `.http` files or pytest suites for client/miner flows.
|
||
- ✅ Document curl examples and quickstart instructions in `apps/coordinator-api/README.md`.
|
||
|
||
## Production Deployment Details
|
||
|
||
- **Container**: Incus container 'aitbc' at `/opt/coordinator-api/`
|
||
- **Service**: systemd service `coordinator-api.service` enabled and running
|
||
- **Port**: 8000 (internal), proxied via nginx at `/api/` (including `/api/v1/*`)
|
||
- **Dependencies**: Virtual environment with FastAPI, uvicorn, pydantic installed
|
||
- **Access**: https://aitbc.bubuit.net/api/v1/health for health check
|
||
- **Note**: Explorer + Users routes are enabled in production (see `/api/explorer/*` and `/api/v1/users/*`).
|
||
|
||
## Stage 2+ - IN PROGRESS

||
|
||
- 🔄 Integrate with blockchain receipts for settlement triggers.
|
||
- 🔄 Add Redis-backed queues for scalability.
|
||
- 🔄 Implement metrics and tracing (Prometheus/OpenTelemetry).
|
||
- 🔄 Support multi-region coordinators with pool hub integration.
