# E13 (cliff) — the real-weight reproductive-isolation curve, mirroring E12's isolation cliff. Two MLPs
# forked from a shared MNIST base; child B learns a CONFLICTING label map on a fraction `conflict_frac`
# of the classes (the rest agree). Sweeping the conflict fraction traces the residual (after-alignment)
# barrier from 0 (no conflict = same species) to its maximum (full conflict = fully isolated) — the
# real-weight image of "the isolation cliff rises with epistasis". Alignment is applied throughout, so
# the curve is the residual that permutation cannot explain away.
