+# Phase 15 Repository Integrity Audit
+
+**Date:** 2026-06-25  
+**Status:** Passed for static package integrity
+
+## Summary
+
+The baseline manifest passed before changes. The Phase 15 audit checks JSON/CSV structure, symlinks, generated files, secret patterns, reserved test email domains, runtime URLs, dependency pinning, and release-control invariants.
+
+## Executed evidence
+
+- Baseline manifest: 466 files verified.
+- Baseline audit exposed 4 High and 7 Medium findings.
+- Current audit reports zero findings under the same controls.
+
+## Unexecuted or blocked evidence
+
+- Final package manifest validation occurs after all reports are generated.
+- Git commit history was not supplied and cannot be audited.
+
+## Release disposition
+
+Static repository integrity is acceptable, but it does not replace build, dependency, browser, or human QA evidence.
