Fields

level: Level

category: String

Coarse category, e.g. "myapp.commit", "myapp.free".

message: String

Human message (should already avoid user data; the writer redacts too).

fields: Value

Structured fields. Keep small and free of user content.

pid: Option<u32>

Which process recorded this crumb. None for crumbs from this process’s own recorder (they are all this process); Some for crumbs read back from a shared, artifact-keyed ring, where the origin is the whole point.
