Minimal PoC for bilateral hierarchical MoE with reconciliation.
Goal: determine if structure yields OOD/generalization signal vs dense compute-matched baseline.
Protocol:
Deterministic task generation (seeded).
Side-by-side training (structured S vs dense D_a) from the same data stream.
Eval every N steps on fixed IID/OOD/structure-break sets.
Early-kill criteria documented in docs/00_north_star.md.
