# C2b (prereg §4a amendment under review): confidence-gated inheritance. The pre-registered C2 failed
# (retention ≤ 0.81 at k ≤ 150 despite competent supply): the child fits eight families of confident
# garbage alongside the one competent family. Here the child learns only prompts its source is
# confident on (verifier-free). Measures retention by gate τ, the Youden τ* separating own- from
# off-family confidence, and the off-family harm of ungated inheritance.
