"method": "Use SOL166's independently proved disjoint-blocker prefilter, leaving3,609 potentially admissible external cells. Introduce148 Boolean deletion choices with exactly9 selected and one Boolean selected-cell indicator per retained external cell. Enforce each selected cell's baseline-pair blockers by (-z OR delete_i OR delete_j), and require at least11 selected external cells; omit row/column quotas and new-new line capacities to make an even weaker necessary relaxation. First one-worker CP-SAT45s to locate a witness or report INFEASIBLE/UNKNOWN. If CP reports UNSAT, independently encode the same formula in CNF with a cardinality network, generate CaDiCaL DRAT and validate with drat-trim and a separate geometric clause audit before claiming any radius9 exclusion. If SAT, independently validate the deletion/cell witness and calculate full axis deficits. Save exact model, seed, counts, coordinates and hashes. One guarded PC worker/external75s for the initial test.",
