Chronicle.Integrity.Entry (chronicle v0.1.1)

Cryptographic commitment to one append-only audit ledger unit.

The digests and the material they were computed from travel together, which is what lets Chronicle.Integrity.verify_entry/5 recompute an entry from the original payload and compare, rather than take the stored digests on trust.

previous_digest is the one field outside @enforce_keys. The first entry in a ledger has no predecessor, and being a genesis entry is the only legitimate reason for it to be nil.
