Cross-Domain Compositional Schema: Future-Sufficient Interfaces, Typed Optionality, and Preserve-or-Reopen Reuse

A bounded architectural and translational preprint defining a typed, partially instantiable cross-domain compositional schema for future-sufficient interface reuse. The schema combines target-relative sufficiency, typed dependency preservation, provenance and restorative descent, optional authority/admissibility fields, and recursive reuse. It reports one prospective conceptual metrology-to-software translation and one formal-proof negative-control/refusal test. Strong domain-native baselines reach the same local decisions; the result is baseline parity, not formal superiority, a universal ontology, or new mathematics.
