On the non-existence of non-trivial Collatz cycles: a conditional formal proof in Lean 4 with documented structural obstructions

28 pages. Preuve formelle conditionnelle modulo trois axiomes externes (BakerSeparation, BarinaVerification, DerivedLargeKBound). Profil d'axiomes minimal (3 axiomes Lean kernel : propext, Classical.choice, Quot.sound). Architecture en 7 théorèmes centraux + auxiliaires, kernel-checked, reproductible via reproduce.sh.

28 pages. Conditional formal proof modulo three external axioms (BakerSeparation, BarinaVerification, DerivedLargeKBound). Minimal axiom profile (3 Lean kernel axioms: propext, Classical.choice, Quot.sound). Architecture: 7 central theorems + auxiliaries, kernel-checked, reproducible via reproduce.sh.

Contribution principale : pas la non-existence inconditionnelle (irréalisable dans le cadre des outils 2026), mais la cartographie rigoureuse des obstructions structurelles qui rend la conditionnalité nécessaire, pas arbitraire.

Main contribution: not unconditional non-existence (unattainable with 2026 tools), but the rigorous mapping of structural obstructions that makes the conditionality necessary, not arbitrary.

Lecture : si les trois conditions externes sont admises (deux hypothèses Diophantiennes + une vérification computationnelle Barina), alors la non-existence des cycles non-triviaux Collatz est prouvée formellement dans Lean 4, kernel-checked. Les axiomes kernel sont ceux que toute preuve Mathlib utilise — ils ne sont pas spécifiques à ce projet.

Reading: if the three external conditions are admitted (two Diophantine hypotheses + one computational Barina verification), then the non-existence of non-trivial Collatz cycles is formally proven in Lean 4, kernel-checked. The kernel axioms are those used by every Mathlib proof — they are not specific to this project.
