What the Coq Code Proves:
The Coq code proves a packaged theorem suite that turns relational truths into existential witnesses for structure, dynamics, and connectivity. Specifically, it demonstrates that under the three axioms, any valid n-ary relation `Rel` on a hyperedge implies:
- A `NestedGraph` NG with the hyperedge in its outer graph, a time `t`, and a weight `w` from the `NestedWeightedTensor`.
- An evolution `f` preserving `Rel`-hyperedges (via `DynamicPreservation`).
- Universal participation of all entities in some relation.
The strong variants unify these under shared NG/`t`, and the vector form adds type-safety. Proofs destruct axioms to construct witnesses, with the binary corollary for specialization.
Meaning of the Proof
The theorems provide a "usable interface" where `Rel e` yields witnesses for topology (NG), annotation (`w`), evolution (`f`), and connectivity. This means relations are operational—destructible for reasoning in domains like physics or social models, with list flexibility for dynamic arities and vector safety for static guarantees. The strong form emphasizes coherence: Structure/dynamics aren't modular but integrated, embodying "relation as reality's unit."
Significance of the Proof
This proof's significance lies in its role as UCF/GUTT's "contract," per axioms yield a coherent model for any domain instantiation. The dual arity shows robustness, preventing errors and enabling scalable proofs. It synthesizes prior propositions into a verifiable backbone, making relational theory computable and rigorous, as a foundation for invariants or simulations.
Implications of the Proof
Implications include representational completeness (relations embed concretely), dynamical adequacy (preserved evolutions for stability like Φ), and no isolation (global connectivity). Practically, destruct witnesses for proofs/simulations; instantiate for domains (e.g., atoms as U, bonds as Rel). It supports layered modeling (inner for mechanisms) and opens temporal refinements, turning philosophy into a predictive engine for multi-scale analysis.
