# lean-guard. Green here means the monomorphic SHA2-128s verify cone
# translated and TYPE-CHECKS — it does NOT yet mean anything is proven. There
# are zero certificates; the proof layers come next. This script grows a
# Phase-2 (proofs) and Phase-3 (axiom audit) section as the pyramid rises,
# exactly like the ed25519 check.sh.
