PSD.3:4.4 - Test material plurality without ranking

Compare each pair only far enough to ask whether the difference changes a downstream move. Preserve incompatibility when one formulation requires evidence, values, boundaries, or interventions that another excludes. Record overlap when formulations can be investigated together.

Do not score, rank, vote, synthesize, or select unless another pattern and authority govern that result. C.17 may characterize novelty, diversity, or use of an already-generated formulation set when that characterization is material. C.18 applies only when the project must govern generation records, descriptors, archives, fronts, telemetry, or retained exploration value. Neither pattern supplies the PSM-specific construction of problem formulations.
