Interpretation Boundary: Audit Log Verification

Purpose of Audit Log Verification

This page defines how audit logs are validated as complete, append-only, and internally consistent records of system activity. Verification focuses on structural correctness and reproducibility rather than interpretation or intent.

Scope of Audit Logs

Audit logs cover state transitions, settlement events, exception handling, and control actions that affect system behavior. Only events produced by the core execution and settlement pipeline are in scope.

Append-Only Verification Rules

Audit log verification confirms that records are written sequentially, are never modified in place, and that any correction is represented as a new entry referencing prior records.

Event Referencing and Traceability

Each audit record must reference the originating event identifiers, timestamps, and execution context required to reconstruct causal order without external assumptions.

Deterministic Replay Validation

Verification includes replaying logged events through the same validation logic to confirm that resulting states match recorded outcomes under identical inputs.

Consistency and Completeness Checks

Audit logs are validated against invariant rules to ensure no gaps, overlaps, or orphaned records exist within defined execution windows.

Boundary Enforcement

Verification applies only to system-generated artifacts. External logs, narratives, or third-party interpretations are explicitly excluded from audit log validation.

Explicit Non-Goals

Audit log verification does not assess correctness of external systems, legal compliance, or user behavior. It validates only the internal integrity and reproducibility of recorded system activity.

Scope and Dependencies

This page is a derivative specification within GMG Engine. It does not define or redefine core primitives such as settlement, determinism, finality, proof, or exception handling. All authoritative definitions are inherited from the locked GMG Engine core primitives.
