We develop AuditLog.AI: a custody-boundary verification method that proves whether exported evidence is byte-unchanged since a verified checkpoint (or enumerates divergence)
We develop
AuditLog.AI:
Proof-of-Unchanged is the only canonical claim
Proof-of-Unchanged
Divergence is informational and non-accusatory
Divergence (informational and non-accusatory)
No audit opinions, no compliance determinations, no clinical recommendations
No compliance determinations, no clinical recommendations.
Verification occurs post-export at custody boundaries

Human Governance & Fail-Closed Execution
AuditLog.AI operates under a strict human-governed, fail-closed execution model.
No anchoring, verification, or public commitment can occur without explicit human approval under institutional authentication.
All critical actions are gated by deterministic rules. If required conditions are not met, execution halts. No partial results, inferred outputs, or adaptive behaviour are permitted.

Human approval is required for every anchoring event
No automated judgment, scoring, or interpretation
Deterministic PASS or divergence outcomes only
Fail-closed execution if integrity or governance checks are violated
Verification remains reproducible without system access
