    "The delta from CRP-035 v1.2 (0.067) is well within the preregistered ±0.15 tolerance.",
    "The 'more-trained-component dominates' alternative interpretation raised in CRP-036 and CRP-037 adversarial notes is REJECTED.",
    "A small effect DOES exist: L4 preserves slightly less behavior (0.825 vs 0.892) and L5 preserves slightly more (0.481 vs 0.458) under equal LRs, consistent with p carrying more signal when equally trained.",
    "The overall compression profile (cliff at L2->L3, plateau at L4, drop at L5-L7) is qualitatively unchanged."

  "not_established_claims": [
    "Any generalization beyond linear-bandit observers.",
    "Any generalization beyond 100 training episodes.",
    "That capacity asymmetry (W has 32 params, p has 4 params) is not itself a confound (CRP-038-R2 registered).",
    "Any philosophical claim."
  ],

  "adversarial_notes": [
    "The remaining most-likely alternative interpretation is capacity asymmetry, not learning-rate asymmetry.",
    "Longer training might reduce the delta further as both W and p converge.",
    "The 10x LR difference in CRP-035 v1.2 accounts for ~0.07 BC_TV at L4 - a small but non-negligible effect."
