Social and Developmental Closure in a Bounded Cognitive Architecture: Population Coupling, Category Formation, Controllability, Relational Persistence, and Finite Life-Course Profiles

The Version 20 Coherence Engine deliberately leaves population coupling, category learning beyond A13 primitives, controllability, relational persistence, and broad service functions unresolved. This paper establishes one bounded companion specification, Paper V v20.1 Extension Profile 1, without changing the parent F/G/L/R/N family, A1-A17 core, or IAP/FHFS discipline. PC supplies finite queued population coupling; CL supplies a finite conjunction grammar and owner-gated category lifecycle; CT supplies executed-action effect estimation; AT supplies separate availability, trust, value, continuing-bond, and successor-goal records; LC supplies a noncognitive finite life-course environment; and RP profiles close memory, action-conditioned world modeling, bounded planning, structured language, and metacognitive reporting. The integrated state uses a disjoint coordinate registry. CT, AT, and metacognitive outputs can influence action only through target-owner validation and next-tick A6 re-entry; W3 and A4′ remain unchanged. Cross-agent messages have at least one logical-tick delay. Environment truth, including natural death, belongs only to ScenarioRunner. The accompanying CTT1-REF witness is a candidate executable implementation of the parent CTT-1 profile, pending independent validation. HLCW-1-DEV exercises a bounded route through Papers I-V and tests zero reduction, replay, ownership, bounds, guarded compilation, loss reorganization, and terminalization, but it is not a claim of complete Paper V trace, perturbation, or SCP-EXT conformance. These artifacts supply development evidence only. They do not supply human-reference equivalence, identification, clinical validity, authentic attachment or grief, or general human-likeness.
