Review findings retained in the record:
  Review round 1 repaired the test capability fixture and exposed a production
  scalar-to-typed capability dependency. Review round 2 closed all-use-set
  admission and added GEP/store/atomic fail-closed cases. Review round 3 checked
  phase, frame, exact payload width, fresh-executor restore, and evidence claim
  boundaries. All complete gates were rerun after the fixes.

Claim boundary:
  These results establish a direct read-only scalar projection from the active
  caught payload. They do not establish an exception arena, object addresses,
  layouts, destructors, RTTI inheritance, complete C++ ABI behavior, benchmark
  throughput, coverage, or vulnerability-discovery improvement.
