# OpenVINO NPU advisory gateway

Bounded Docker-bridge wrapper for the classifier, GenAI worker, and doc/image triage sidecars.

- HTTP bind: `172.19.0.1:18830` for `n8n-agent` on the `swarm_default` Docker bridge
- Service: `openvino-advisory-gateway.service`
- Mode: advisory/shadow/draft only
- Metadata log: `~/.local/state/openvino-advisory-gateway/events.sqlite`

## Authority boundary

Every response includes an explicit authority block:

```json
{
  "may_route": false,
  "may_write_memory": false,
  "may_send_external": false,
  "may_process_private_dirs": false,
  "may_execute_tools": false,
  "may_restart_services": false
}
```

This service may provide hints and drafts. It must not become the live Atlas/Hermes router, memory writer, primary chat model, external sender, tool executor, service restarter, or broad private document processor without a separate approved integration.

## Endpoints

```text
GET  /healthz
POST /v1/advisory/classify
POST /v1/advisory/generate
POST /v1/advisory/triage
```

## Cron and n8n advisory dry-run contract

For cron/n8n event classification, use the dry-run contract in `docs/cron-n8n-advisory-classifier.md`.
It defines the normalized event envelope, decision envelope, `suppress|log|summarize|escalate` recommendation mapping, and duplicate/stale/no-op/action-required examples.

Example artifacts:

- `examples/cron-advisory-dry-run.sh` — host-local cron wrapper that prints one compact decision line and performs no side effects.
- `examples/n8n-advisory-dry-run-fragment.json` — sanitized inactive n8n node fragment for Set -> HTTP Request -> Code decision mapping.

Both examples preserve the gateway authority boundary: advisory only, no send/restart/memory/tool/routing authority.

### Classifier shadow call

```bash
curl -fsS http://172.19.0.1:18830/v1/advisory/classify \
  -H 'Content-Type: application/json' \
  -d '{"trace_id":"smoke","text":"Urgent: inspect service health and systemd status."}' | jq .
```

### Bounded GenAI draft

Allowed jobs: `title`, `summary`, `notification`, `memory_candidate`.

```bash
curl -fsS http://172.19.0.1:18830/v1/advisory/generate \
  -H 'Content-Type: application/json' \
  -d '{"job":"title","input":"Summarize a local health check.","max_new_tokens":24}' | jq .
```

### Explicit-file doc/image triage

```bash
curl -fsS http://172.19.0.1:18830/v1/advisory/triage \
  -H 'Content-Type: application/json' \
  -d '{"path":"/home/will/lab/swarm/openvino-doc-image-triage-npu/samples/synthetic_invoice.png","allowed_roots":["/home/will/lab/swarm/openvino-doc-image-triage-npu"]}' | jq .
```

The gateway requires the path to be inside both:

1. a configured allowed root on the gateway process; and
2. the request's explicit `allowed_roots` list, if one is provided.

Requests cannot broaden the process-configured roots. Do not broaden configured roots to private folders without explicit approval for that root and task.

## Install / run

```bash
install -m 0644 openvino-advisory-gateway.service ~/.config/systemd/user/openvino-advisory-gateway.service
systemctl --user daemon-reload
systemctl --user enable --now openvino-advisory-gateway.service
systemctl --user status openvino-advisory-gateway.service --no-pager
```

`--allowed-root` may be repeated in the systemd unit when additional non-private fixture/review directories are approved. Docker bridge exposure must use `--allow-docker-bridge` and the approved bridge IP `172.19.0.1`; the service still refuses wildcard binds such as `0.0.0.0`.

From `n8n-agent`, verify bridge reachability with:

```bash
docker exec n8n-agent wget -qO- -T 8 http://172.19.0.1:18830/healthz
```

## Tests

```bash
cd /home/will/lab/swarm/openvino-advisory-gateway
python -m pytest tests/test_gateway.py -q
```
