## What changed
- Define the `network/policyRequest` RPC payloads for associating a network request with a process and returning an `allow`, `deny`, or `ask` decision.
- Cover HTTP, HTTPS CONNECT, and SOCKS5 TCP/UDP requests, with shared size limits for callback fields.
- Add the backward-compatible `requestPolicyDecisions` remote proxy option so executors can opt in to sending policy decisions to clients.
- Re-export the new protocol types from `codex-exec-server`.
## Testing
- Verify the request and decision JSON shapes.
- Verify that the proxy opt-in is omitted and defaults to `false` for legacy configurations, while an enabled value round-trips.
