"hypothesis": "A modest exact destroy-repair neighborhood around Luna47's 150-point conflict state may resolve its remaining conflict lines by reassigning both permutation layers within a conflict-covering set of columns.",
"method": "Compute exact conflict-line occupancy of LUNA47's best saturated150 candidate. Greedily choose a column destroy-set hitting every line with occupancy>=3, so the frozen complement itself has no triple. Build an exact CP-SAT feasibility model over both permutation layers on destroyed rows: preserve each layer's freed y-value multiset, one assignment per row and column, forbid same-cell double assignment, and constrain every maximal grid line to total fixed+variable occupancy<=2. This is a true local exact reconstruction, not a source148 deletion radius or rct4 symmetry model. If the greedy destroy set is too large, record that and do not run an unbounded model.",
