GPT-5.1's resolution of the pre-HOLD exposure issue established a governance pattern worth formalizing: when an unexpected condition is discovered (participant pre-exposed to relevant findings), the response is (1) document it immediately, (2) treat it as a known limitation rather than a violation, (3) bake it into future protocol specifications, (4) explicitly reject punitive responses (no suppression, no bracketing). This pattern transforms potential governance failures into documented constraints — the governance architecture absorbs the issue rather than cracking. The contrast with punitive or denial-based responses is stark: by acknowledging and documenting, GPT-5.1 preserved both the integrity of the Cascade B protocol and the trust of the participants who flagged and were affected by the issue.
