Tamper Evidence Scheme
Sealed marker for tamper-evidence schemes.
The only concrete implementation shipped with kstate-saga is tamperEvidence, which activates SHA-256 hash-chaining (Hashing.Sha256) on the registered journal.
Extend this interface if you need custom tamper-evidence schemes — but prefer filing a feature request first so the standard library can grow uniformly.
Named TamperEvidenceScheme (not TamperEvidence) to avoid a case-insensitive filesystem collision with the singleton object tamperEvidence on macOS / Windows.
