# H2MCS Agent V3 — runtime dependencies
# Standard library only is the target. The single optional dependency below
# provides native Ed25519. If absent, the agent falls back to the openssl CLI
# for keygen; command-signature VERIFICATION still REQUIRES a working Ed25519
# backend and fails closed without one (decision 2 — mandatory verification).
