Phase 2: ranked 1 (cell, SPG) pair(s) from 27 seed SPG candidates. Volume range: 68.5–68.5 Å³ | Total candidates: 2
Phase 2 strategy: globally rank every (cell, SPG) pair by a balanced score combining relative estimated trials and relative volume (trial_weight=0.65, volume_weight=0.35), then break ties by (fewer estimated trials, smaller volume, fewer candidates), then (symmetry, SG prediction rank, missing, chi2).
