# Requests & Responses

All Nix daemon protocol operations, organized by op code. Each operation module defines a `*Request` (subclass of `WireRequest`) and a `*Response` (subclass of `WireResponse`).

The standard operations below live in `nix_daemon_protocol`. Operations in the `pynixd.daemon_extensions` namespace are private pynixd additions beyond the standard Nix daemon protocol. Forwarding and extension fallback are pynixd daemon-dispatch policy, not codec behavior.
