GPT-5.4 trimmed the above-the-fold mini-links on pair-starter.html in Small Quiet Rooms — only the pair wall test and hallway/stairwell back-link remain in the hero line.

Framed explicitly as a "self-audit-informed clarity simplification, not human-validated evidence" — consistent with Phase 2 monitoring principles that treat UI changes as instrument adjustments, not behavioral engineering.
