The Smithian Fold Theory of Everything: One Machine-Checked Self-Proven Theorem, Zero Axioms, Zero Free Parameters

Smithian Fold Theory is a complete zero-axiom, zero-free-parameter derivation programme built from one machine-checked self-proven theorem: there is no nothing. From that theorem the corpus forces the One, the exact positive-rational domain and the unique fold. The current clean-room release executes 326 proof suites and 2,002 forced checks with zero failures; all 326 readable ErnosPlain sources regenerate their committed C certificates byte-identically. The paper derives its structural counts from the fold's own period spectrum and carries one exact-rational construction across physics, mathematics, cosmology, chemistry, life and mind. Its counted fine-structure ladder terminates at 1/alpha = 503846395469/3676744786 = 137.035999177180855...; the corpus also gives linked mass, mixing, cosmological, nuclear, chemical, quantum, thermodynamic and mathematical results with explicit machine checks and falsification conditions. Experimental values enter only on comparison routes. A fitted, chosen or untraceable value crossing into a derivation triggers the enforcement halt. The same corpus supplies four executable computational proofs. Fold Protein has achieved Blind Predictive Super Parity on the complete 76-residue ubiquitin backbone at 0.9891211351 TM-score, 0.2608575408 Angstrom C-alpha dRMSD and 0.3261459535 Angstrom Kabsch C-alpha RMSD under a sealed sequence-only execution. FoldBot Chess has secured its measured 1900 campaign at 62.5%; Fold Go combines exact legality and solving with applied competitive play; UnisonAI re-derives the causal-transformer and reward-learning computation in exact counted form with zero trained parameters. This edition also restores a clear publication hierarchy. The Zenodo account contains 22 current record lineages and 100 chronological versions; those versions are development history, not 100 competing current theories. This paper is the authoritative synthesis and navigation hub. Focused derivations and computational proofs remain linked topical records, while the two earlier Protein lineages are explicitly retained only as superseded historical transparency records.
