Publishes a service's own event into a consenting tenant environment. Requires events:publish and the exact events:platform:<service> scope. A webhook_uri selects exactly one registered endpoint in that environment; admission atomically stores its signed, retried delivery, or stores nothing.

- **Path** `POST https://api.sylphx.com/v1/events:publishServiceEvent`
- **Scope** `events:publish`
- **Effect** `write` — a successful call changes state.
- **Collection** [events](/docs/api/events)
