      "interpretation": "The exact empty-grid MRV constructor is sound on its emitted92-point state, but the current branching/order plus 5,000-node cap reaches dead ends after roughly46 rows, far below the known148 incumbent. This rejects only this bounded implementation/run, not all row-wise backtracking or the existence of150. The 92-point state is a new low-cardinality valid configuration, not a competitive incumbent. No globally reusable memory promoted: result is specific to this constructor and budget; existing domain-screen memory already captures the broad need for propagation.",
