Reproduction harness
Which geometric capability produces the gain — not which paper won a table. Twelve cells, one protocol. No number appears here until its ancestry hashes close.
One implementation, six factor switches, two endpoint modes. atlas-kg-v1 (synthetic, 48 entities, seed 7) is bound. FB15k-237 is not. Do not read 0.402 into these cells.
12/12 atlas-kg-v1 cells bound · FB15k-237 still unbound
Synthetic 48-entity atlas-kg-v1. Not FB15k-237. Does not reproduce FlorE 0.402. One seed. M5 geodesic displacement is not implemented in the trainer (falls back to M3 score).

QD_σ vs Q vs QB
Same data, seed, trainer. One run. Not a general result. A is the only non-isometry.
