"""Canonical unit-class taxonomy shared by cache, models, and evals.

STATIC_CLASSES are persistent structures the spatial AE compresses.
TRANSIENT_CLASSES (mobile/projectile) bypass the AE: they are few, exact,
and fully described by (owner, type, position, target) — the policy reads
them raw instead of through a lossy latent.
