Protocol events

The 108 canonical event types a Harbor Runtime can publish, read from the live event-type registry (internal/events) as the production driver set populates it. Subscribe via GET /v1/events (SSE) — see methods.md and the streaming semantics guide.

How payloads reach a subscriber

Every SSE frame's data: line is one JSON object: type, sequence (the reconnect cursor), occurred_at, the flat identity (tenant / user / session / run), and payload. Two payload classes exist:

• Safe payloads — types the declaring subsystem marked as carrying no secret-shaped data. The bus skips the audit redactor; the subscriber receives the typed shape below verbatim. Field keys are the Go field names (e.g. TaskID, capital T).
• Redacted payloads — everything else is walked by the audit redactor on publish; the subscriber receives a redacted key/value map derived from the declared shape.
