Why the Paton Foundation Locks Formally: Logic, Category Theory, and the Tier-0 → Tier-3 Spine

The Paton System proposes a structural framework describing the minimal conditions required for systems to exist and continue. The foundational tiers of the framework—Tier-0 through Tier-3—describe the emergence of reference, distinction, relational interaction, and admissibility. This note observes that these tiers correspond closely to minimal requirements found in formal logic and category theory. The alignment suggests that the Paton foundation reflects structural necessities already present in formal systems. Rather than introducing a competing mathematical framework, the Tier-0 → Tier-3 spine can be interpreted as a minimal ontology describing the structural conditions under which formal systems become admissible.
