Excerpt from `templates/gate-and-act.nika.yaml`, source lines 32–41. This is a fragment, not a runnable workflow.

```yaml illustration theme={"system"}
permits:                            # the blast radius · default-deny once present
  tools: ["nika:fetch", "nika:notify"]
  net:
    http:
      - "api.example.com"           # SLOT: the watched host from const.source_url
      - "hooks.slack.com"           # SLOT: the host ALERTS_WEBHOOK_URL points at.
                                    #   `host_from_self` below means the host is not
                                    #   knowable at check — it is judged at RUN against
                                    #   this list, so an unnamed host fails mid-flight.

## Contract and implementation

This page projects the named specification revision. Check [released engine status](/reference/status) and [the validation workflow](/guides/agent-authoring) before running a file. An optional field is not evidence that every engine supports every value.

Canonical identity: `language:word:http`. Spec revision: [`c5ebbb7b862b`](https://github.com/supernovae-st/nika-spec/tree/c5ebbb7b862b68bc6cf7235efba61173b844afc6).
