## Summary This adds `experimental_network.danger_full_access_denylist_only` for orgs that want yolo / danger-full-access sessions to keep full network access while still enforcing centrally managed deny rules. When the flag is true and the session sandbox is `danger-full-access`, the network proxy starts with: - domain allowlist set to `*` - managed domain `deny` entries enforced - upstream proxy use allowed - all Unix sockets allowed - local/private binding allowed Caveat: the denylist is best effort only. In yolo / danger-full-access mode, Codex or the model can use an allowed socket or other local/private network path to bypass the proxy denylist, so this should not be treated as a hard security boundary. The flag is intentionally scoped to `SandboxPolicy::DangerFullAccess`. Read-only and workspace-write modes keep the existing managed/user allowlist, denylist, Unix socket, and local-binding behavior. This does not enable the non-loopback proxy listener setting; that still requires its own explicit config. This also threads the new field through config requirements parsing, app-server protocol/schema output, config API mapping, and the TUI debug config output. ## How to use Add the flag under `[experimental_network]` in the network policy config that is delivered to Codex. The setting is not under `[permissions]`. ```toml [experimental_network] enabled = true danger_full_access_denylist_only = true [experimental_network.domains] "blocked.example.com" = "deny" "*.blocked.example.com" = "deny" ``` With that configuration, yolo / danger-full-access sessions get broad network access except for the managed denied domains above. The denylist remains a best-effort proxy policy because the session may still use allowed sockets to bypass it. Other sandbox modes do not get the wildcard domain allowlist or the socket/local-binding relaxations from this flag. ## Verification - `cargo test -p codex-config network_requirements` - `cargo test -p codex-core network_proxy_spec` - `cargo test -p codex-app-server map_requirements_toml_to_api` - `cargo test -p codex-tui debug_config_output` - `cargo test -p codex-app-server-protocol` - `just write-app-server-schema` - `just fmt` - `just fix -p codex-config -p codex-core -p codex-app-server-protocol -p codex-app-server -p codex-tui` - `just fix -p codex-core -p codex-config` - `git diff --check` - `cargo clean`
