Summary

A randomized byte-exact oracle caught a post-quantum signing defect that fixed vectors never reached.

The deployed-silicon case study reports 301,343 randomized signings with no escapes after replacing the gate, plus a 779,945-check zero-failure soak across six FIPS operations. AI authorship remained less reliable near physical bring-up.

Why it matters
