Nova-Z Runtime Notes

Quickstart

- Install deps: `pip install -r requirements.txt`
- Configure env: copy `.env.example` to `.env` and set `API_KEY`. Optionally set `MODEL_PATH` for local weights or leave and use `HF_MODEL_ID`.
- Start API: `python serve.py`
- Test: `python test_api.py` or `python examples/stream_client.py`
- Baseline eval: `python phase0_eval.py` (uses EVAL_ROOT; generates sets if missing)

Project Home

- Canonical directory for Elizabeth assets: `/data/adaptai/projects/elizabeth`
  - `evaluation/` (default EVAL_ROOT)
  - `artifacts/` (eval reports)
  - `docs/` (roadmaps, memos, identity docs)

Key Env Vars

- `API_KEY`: required bearer token for API calls
- `METRICS_KEY`: optional; if set, `GET /metrics/prom` requires `Authorization: Bearer $METRICS_KEY`
- `MODEL_PATH` or `HF_MODEL_ID`: local weights path or HF repo id
- `ALLOW_ORIGINS`: comma-separated origins for CORS (defaults to localhost)
- `REDIS_HOST/PORT/PASSWORD`: memory backend (optional; service works without it)
- `API_BASE`: client base URL for tests/examples
 - `EVAL_ROOT`: Phase‑0 eval location (default `/data/adaptai/projects/elizabeth/evaluation`)
- `EVAL_LIMIT`: Cap examples per set (0 = unlimited)
 - `EVAL_STRICT`: If set to 1/true, `phase0_eval.py` exits non‑zero on FAIL

Streaming Notes

- Set `"stream": true` in the request body to receive Server-Sent Events.
- Final non-standard `chat.completion.usage` event includes token counts.
- Non-stream responses include `usage` inline.

Monitoring

- Prometheus scrape example (with metrics auth):

```yaml
scrape_configs:
  - job_name: "elizabeth"
    metrics_path: /metrics/prom
    scheme: http
    static_configs:
      - targets: ["localhost:8000"]
    authorization:
      type: Bearer
      credentials: "<your-metrics-key>"
```

- If you don’t set `METRICS_KEY`, omit the `authorization` block.
