Syntropic Constraint Architecture

Syntropic Constraint Architecture presents a constraint-first systems-engineering framework for evaluating spacefaring architectures through eight noncompensable physical, economic, human, resilience, stewardship, and governance constraints. It introduces a hierarchical dependency graph, a two-stage static-to-runtime admissibility process, a cascaded failure-propagation operator, and evidence-based provenance tracking. The framework is presented as a falsifiable research methodology, with provisional thresholds and coupling parameters requiring empirical calibration. It is not proposed as a flight specification or certification standard.
