"hypothesis": "The four CP-SAT presolve rejections afterSOL158 capacity-feasible large new50 repairs may be explained by replayable elementary 0/1 saturation contradictions, yielding independent local certificates and causal deletion targets.",
"method": "For each savedSOL158 fixedcomplement reconstruct exact row/column equalities and every necessary oblique line cap over eligiblecells. Propagate zero-cap and saturated equalities to fix candidate cells until contradiction orfixpoint; save each reasonconstraint and parent chain. Independent checker recomputes every constraint support geometrically, replays forced assignments and contradiction, revalidates originalblocked-cell domains and full axisflow witnesses. If no elementary contradiction, record fixpoint rather than assertingUNSAT. No changes to the four CP models or final fixedpoints.",
