Build Week 2026.1: Adversarial contract evidence
This incremental Build Week release hardens the Codex-to-MATLAB boundary with a reproducible adversarial benchmark.
- Accepts one checked GPT-5.6 control review
- Rejects 14/14 hostile mutations fail closed
- Covers executable-action injection, candidate/model spoofing, field smuggling, invalid scores, contradictory verdicts, oversized findings, and malformed JSON
- Commits human-readable and machine-readable evidence
- Runs the benchmark in the release gate
