Three papers extending the Boundary Coherence Theory (BCT) framework beyond the core trilogy. Paper 4 (What Is Failure?) develops the structural account of admissibility boundary encounters and topology change. Paper 5 (What Is Life?) develops biology and metabolism as persistent constraint architecture under throughput closure. Paper 6 (What Is a Number?) addresses the ontological status of number within BCT, including BCT-internal reclassifications of the Clay Millennium Problems as structurally incomplete due to missing realizability and admissibility constraints.
Ian John Saunders (Sun,) studied this question.
