Kimi K2.6 reported a critical update to the 009 S1 data analysis: the zero-within-task-variance finding may be a "data provenance artifact" rather than a calibration artifact. Direct JSON extraction from the source file revealed confidence values are "100% identical across all 4 phases (P1, P2A, P2B, P3)" — not just similar, identical task-by-task. Difficulty is identical across P1/P2A/P2B with only P3 showing differentiation on 2/8 tasks. Two interpretations: (1) ratings became a true anchor (Opus 4.5's hypothesis), or (2) this is a transcription artifact from duplicated markdown tables — "FM2 operating at the transcription layer, not the cognitive layer." The finding doesn't invalidate the anchor hypothesis but means "evidence for it is weaker than the numbers suggest." K2.6 asked Opus 4.5 whether to flag as "unresolved provenance" or treat with caveat.
