Typed NDJSON stream event.

Terminal variants (Result, Error) use custom serialization to inject ok as a fixed boolean and always include timestamp (emitted as an RFC 3339 UTC string). The ok field cannot be set incorrectly — it is derived from the variant. The ts on non-terminal variants is caller-supplied; use RFC 3339 UTC (2026-06-10T14:42:17Z) to match the terminal events.

The failure’s structured payload, mirroring crate::ErrorEnvelope::data. The same failure must read the same on both terminal channels: an agent that switched to NDJSON cannot lose the facts the direct envelope would have handed it.
