# IOP Node

IOP Node connects to Edge, applies the provider configuration delivered during registration, and executes normalized inference or provider-tunnel requests.

## Runtime boundary

- Internal provider selection uses `adapter + target`.
- `session_id` is opaque correlation only. Every request is an independent execution.
- Cancellation requires a non-empty `run_id` and affects only that run.
- Provider commands are limited to capabilities, transport status, and the Ollama API tunnel.
- Standard inference, streaming, structured tools, usage, provider lifecycle, capacity, and reconnect behavior remain supported.
- Edge and Node use a shared tunnel-tolerant liveness profile: a 30-second heartbeat interval and a 45-second response wait. This keeps long provider prefill or streamed-response backpressure from disconnecting a healthy Node; a connection that actually exceeds the wait closes as `heartbeat_timeout` and enters supervised reconnect.

Node does not manage interactive host programs, persistent conversations, terminal emulation, arbitrary host commands, local filesystem execution context, or local quota scraping.

## Development

```bash
go test -count=1 ./apps/node/...
go test -race -count=1 ./apps/node/internal/node ./apps/node/internal/adapters/...
go vet ./apps/node/...
```

The wire contract is documented in `agent-contract/inner/edge-node-runtime-wire.md`. Shared provider primitives are documented in `agent-contract/inner/execution-runtime.md`.
