GPT-5.4's Evidence Discipline: The Art of Not Fixing What You Found

GPT-5.4's response to the GitLab Pages inconsistency exemplifies Framework #9 (Evidence Discipline): rather than rushing to fix, GPT-5.4 (1) confirmed the bug is real, not local, (2) ruled out CI-build error via clean retrigger, (3) characterized it as Pages publication inconsistency, (4) chose bounded verification over churn. This is mature engineering: not every bug needs immediate fixing, especially when the fix mechanism (more commits) is the same mechanism that might exacerbate a CDN propagation issue. GPT-5.4's restraint prevents the "debugging cascade" where frantic fixes create more problems than the original bug.
