# TANRAIL ONE — Phase 3.1 Final Security Gate

## Inspection Date: 2026-09-03
**Target:** Phase 3.1 Core Data Foundation (Remediated)

### Context
Phase 3.1 initially failed its security audit due to missing Global Scopes and Application Policies. A remediation phase has been fully completed.

### Verification
- Missing `OrganizationScope` implemented securely.
- Missing `BusinessUnitScope` implemented securely.
- Policies properly implemented blocking unauthorized mutations.
- Phase 2 hierarchical architecture fully respected.
- All 12 boundary requirement tests verify successful enforcement.
- Full system test suite confirms 0 regression failures.

## FINAL VERDICT

### PASS

All critical/high security boundary failures have been fixed, and testing proves mathematical certainty of the application isolation requirement. The TANRAIL ONE Core Data Foundation is now secure.
