Audit trail
Immutable ledger
Every action is appended to a hash-chained timeline so auditors can verify integrity.
How we're different
- Evidence system of record, not a case tracker.
- Immutable timeline and explicit approvals with no silent overrides.
- Examiner-ready binders with linked artifacts and tamper-evident logs.
Trust rule: AI drafts, humans decide for sensitive outcomes.
Append-only events with prev_hash and event_hash.
Verification endpoint to check chain integrity.
Exportable logs for exam teams.
