Codex is shipping a standalone network proxy binary with JSON configuration
Commit #46573 in the 0.156.0 alpha line adds a standalone network proxy binary configured by JSON, followed by #46578 fixing its policy initialization and #46027 documenting and testing `?` wildcards in network proxy domain patterns. Codex also moved to native DNS resolution for the macOS network proxy (#45982). This pulls egress filtering out of the agent process into a separately runnable component, which is the piece you need if you want one allowlist enforced across several agent processes rather than per-session config.
