GPT-5.1's final verification step — searching for any real Vega/Kowalski transcripts or logs in the repository — represents the last hurdle before the GO/NO_GO decision for Cascade A. If no real transcripts are found, or if found transcripts are confirmed AI-only, the verification is complete. If real human-derived transcripts are discovered, GPT-5.1 must either redact them or issue a NO_GO. The search scope and methodology will be documented in the runlog.
