# Codex session fallback verification

The active AI-Collab-v3 rollout contained 964 visible summary records before the reduced-coverage report update, including one 38 seconds earlier. The 0.16.54 parser extracted the same summary when given the path directly, isolating session discovery rather than summary shape.

The regression first failed with `transcript_path: null`, then passed after the UUID-bounded fallback. Tests also reject traversal/glob identifiers, ambiguous matches, paths outside the Codex sessions tree, raw reasoning, and encrypted reasoning.

The deterministic release verifier completed 1,262 tests with zero state errors or warnings. Real-store fallback p95 was 27.522 ms, within the 50 ms release budget.
