Structural, lossy metadata emitted by the Kernel.

This enum intentionally has no payload, configuration, secret, opaque extension, ActorAssertion, or Domain Error fields. Delivery of these records is not itself observed, so exporting a record cannot recurse into the diagnostic feed. Caller identities are present only when they resolve to a Module Instance in the immutable App Plan.
