Function record_event 

pub fn record_event(event: LogEvent)

Emit one event. Always fans out to the broadcast hook + tracing event. If persistence is enabled, hands the serialized value to the disk worker via a bounded try_send. The hot path performs no file I/O.

The broadcast copy carries ephemeral_attributes deep-merged into attributes (live SSE consumers may render short-lived pairing credentials); the persisted copy never does — LogEvent marks the field serde(skip), so the serialized value below is credential-free by construction.

This is the function the record! macro expands into. Direct callers (the schema migration tool, tests) can invoke it too, but production code should go through the macro so the tracing::event! carries the correct file:line source info.
