  "supported_claims": [
    "NNMO exhibits an immediate compression cliff: BC_TV drops from 1.000 (N0) to 0.459 (N1), a loss of 0.541.",
    "The N1..N4 plateau (BC_TV = 0.43-0.46) indicates compression is essentially step-shaped in NNMO.",
    "Even minimal memory retention (N4: one argmax-reward action) lifts behavior modestly above the random baseline (gap 0.136 TV, 0.146 AM).",
    "CROSS-ARCHITECTURE: parameterized observers (CRP-035 L4) preserve BC_TV=0.892 with 32 numbers retained; memory-based observers (CRP-037 N1) preserve BC_TV=0.459 with ~100 numbers retained. Identity carrier is not just capacity but capacity IN THE DECISION RULE.",
    "Value preservation breaks earlier than behavioral continuity (VP drops from 0.545 at N1 to 0.21 at N2/N3)."
  ],

  "not_established_claims": [
    "That memory-based observers universally require exact-memory retention (CRP-037-R1 registered).",
    "That the cliff shape survives different clustering algorithms.",
    "Any generalization to third architectures (CRP-037-R2 registered for PP observer).",
