Interface SignatureProvider

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface SignatureProvider
Sign / wrap an audit JSON document for tamper-evident persistence. Default identity — returns the JSON unchanged. Callers can plug in implementations such as HMAC or Ed25519 signing.

Per CONTRIBUTING.md "Engineering principles" §2 — when this is invoked, callers know the sealed JSON they get back is what hits long-term storage.

Since:
0.1.0
