Irreducible Triad, Interface Compatibility, and Coherence in Artificial Agents: A C-Theory Note

This record contains a companion note to CT framework that formalizes the “irreducible triad” stance for the P–I–E kernel (constraints/physical substrate P, interface/projector I, and experienced stream E). It introduces CT-oriented criteria for coherence vs incoherence in artificial agents, proposes a working definition of “interface compatibility with E” as a systems-level closure property (stability, revision-without-tearing, and constraint anchoring), and clarifies the common EM-field vs photon-quantization confusion (quantized exchange does not negate effective field continuity at relevant scales). The note is intended as a compact, citable bridge between CT foundations and AI/sentience debates, and invites critique, replication attempts, and alternative formulations.The note also adopts a CT-compatible privatism: E (experienced state) is first-person given and cannot be directly known by other observers, only inferred via mappings (I) under constraints (P); thus behavioral or physical correlation does not by itself resolve identity of experience.
