Struct SnapshotFingerprint 

pub struct SnapshotFingerprint(/* private fields */);

The checksum a sealed snapshot already carries, reborrowed as its change fingerprint: two seals of identical payloads carry identical fingerprints, so a flusher can skip rewriting a region whose fingerprint matches its last flush — no second hash pass. A changed payload whose CRC-32 collides with the previous one (odds 2^-32 per flush) skips one write; the next real change heals it.
