System and Method for Execution-Time Deterministic Finality and Regulatory Reliance Across Multi-Domain State Transitions

This technical specification defines a cross-domain finality layer for regulated state transitions using execution-time cryptographically bound evidence. The specification establishes a uniform mechanism for determining whether a regulated decision or payout is final based on the presence of valid execution-time evidence lineage, deterministic acceptance tokens, and auditable override context. The specification applies across multiple regulated domains—including payments, insurance claims, wagering, government disbursements, escrow and fund control, and entitlement systems—without redefining domain-specific evidence creation or acceptance mechanisms. Instead, it provides a standardized finality determination framework that consumes upstream execution-time primitives and produces an authoritative finality or failure-of-finality outcome. Under this framework, absence of valid execution-time acceptance evidence constitutes finality failure and cannot be cured through reconstructed records, narrative explanations, probabilistic scoring, or post-hoc interpretation. Any deviation from evidence-based finality requires invocation of a constrained, auditable override workflow. This specification enables regulators, courts, payment networks, and oversight authorities to evaluate finality decisions based on objective, execution-time evidence rather than retrospective documentation, improving consistency, transparency, and cross-domain regulatory reliance.
