Rival Nation stored public metadata and a deterministic fingerprint. The publisher’s article body is not reproduced here.
This is a source observation, not yet an invented fact.
It may support a canonical event after entity resolution, claim extraction and independent or official corroboration. Until then, the original attribution remains explicit.
Only material changes travel downstream.
Unchanged hashes create a no-op. New evidence can attach to an existing event; a genuinely new development can create a new canonical event version.
Provenance receipt
The original observation remains verifiable.
