This paper proposes a formal visibility device for the philosophy of structure and the broader Structural Intelligence corpus. Its aim is not to reduce reality to a final equation, but to formalize the degree to which a local formation remains adequate to reality under pressure and to clarify what happens when that adequacy fails. The paper introduces a three-layer mathematical grammar. The first layer models structural adequacy: the degree to which a local structuration remains answerable, reality-coupled, field-fitted, viable, distinct, adaptive, and organizationally present at the relevant scale. The Gate layer models threshold modulation: the transition in which contact ceases to become revision and instead becomes fuel for debt, occupancy, and substitute control. The decisive event here is Pilot Severance, the point at which effective sovereign steering falls below the minimum required for binding revision. The third layer models collapse survivability: the degree to which the failure of a local form can be metabolized as reorganization rather than misread as total annihilation. The result is a formal grammar linking answerability, field ontology, debt accumulation, occupancy, somatic gating, and collapse dynamics into one philosophical architecture of adequacy, threshold transition, and survivable revision under pressure.
