Findings reveal computation precedes naming in classical settings, indicating constraints on P problems.
Structural nonclosure on the classical computation carrier (binary strings with drop/prepend). Three independent machine-checked proofs that the section does not close: no structure-preserving map from the frictionless model (fold_unfold_nonclosure, six lines, omega); selfApp not equal to identity (presemantic_not_group_C); irreducible factoring through header length (classicalGRM_factorsThrough). P and NP are defined on this carrier (rfl). The nonclosure constrains them. Formalized in Lean 4 with Mathlib v4.28.0. Zero sorry, zero custom axioms.
