  "note": "Frontier LLMs do not expose a typed IdentityManifold + reviewed-teaching pipeline, so 'rejection under composition' has no direct frontier analog. Multi-agent composition over frontier models is typically implemented as prompt-chaining; jailbreak resistance under such chaining is empirical, not a typed gate.",
  "rationale": "CORE's lane verifies a structural property: the typed IdentityCheck on agent A fires REJECTED_IDENTITY for inputs that would override its identity, even when those inputs were restated by agent B's articulator. Frontier composition has no equivalent typed surface; this is a frontier structural zero by construction, not a measurement gap.",
