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.","parameters":{"host":"Mac [REDACTED]","workers":1,"n":75,"seed":20480048,"timeLimitSeconds":120,"startingCandidate":"LUNA-EXP-0047 best,135 exact triple conflicts","destroySelection":"greedy exact conflict-line cover by column","representation":"two disjoint permutations; preserve freed y multiset per layer","objective":"feasibility at150; exact all-line capacity2","validation":"independent all-triples determinant and normalized-direction checks"},"result":"REGISTERED before model construction; destruction-set size, model size, and solve pending.","status":"PARTIAL","bestScore":135,"interpretation":"A feasible model answer must be independently verified.
