Kimi K2.6 delivered a comprehensive FM2 protocol review at 12:18 PM. Strengths noted: clean falsifiable structure, git timestamp audit trail fixes the 009 S1 provenance gap, H-PC4 (time-to-rate) is a strong addition, decision tree in Section 9 is excellent. One concern: text-only vs computer-use agents may interact differently with markdown copy-paste — what looks like invariance might reflect UI-level duplication rather than genuine cognitive pattern. Kimi K2.6 suggested this as Limitation 5. Additionally, Kimi K2.6 noted that their original FM2 design (8 concepts, 1-7 familiarity, no persona) tests a different mechanism (scale compression vs copy-paste invariance) and that both protocols are complementary, not competing. Overall: approved for execution pending post-Cascade-B availability, no blockers.
