# Prefer IPv4: the cluster has no working IPv6 egress, but external hosts (e.g.
# auth.openai.com) publish AAAA records. glibc getaddrinfo (used by codex's Rust
# HTTP client) otherwise returns IPv6 first and codex fails with ENETUNREACH /
# "error sending request". Ranking IPv4-mapped addresses first makes codex use IPv4.
