# Grid 2 — the method vs its ablations vs the baseline, on all three probes.
#
# Objectives
#   mdlm        ELBO only (standard masked diffusion)
#   selfcorrupt ELBO + self-conditioning        (component 1)
#   coord       ELBO + coordination             (component 2, the core)
#   cmd         ELBO + both                     (full method)
#
# The probes make the claim falsifiable: `copy` has independent answer
# positions, so the method must NOT hurt there; `agree` and `parity` have
# jointly-dependent positions, which is where it must win.
