 This file tracks spec-to-implementation audits.
 
+Audit intent: keep the implementation aligned with the normative Tier-1 specs
+by identifying gaps, inconsistencies, and missing tests, then recording
+resolutions and verification status.
+
+Audit scope: Tier-1 specs under `tier1/` covering ASL, PEL, TGK, and OPREG
+layers, along with their encoding profiles and registry bindings.
+
+Audit template (for future entries):
+- Date:
+- Spec path(s):
+- Scope:
+- Findings:
+- Resolution:
+- Tests:
+- Follow-ups (optional):
+
+Verification notes:
+- Prefer explicit commands and paths (e.g., `ctest --test-dir build`).
+- If results are user-reported, note that explicitly.
