Code Craft AI Networking

The codecraftai-networking package is the low-level networking toolkit for the ccai suite. It provides the reusable primitives that higher-level protocol, discovery, and landscaping packages build on top of, without pulling in any heavy third-party networking stacks. Downstream packages such as codecraftai-interop (DNS/mDNS), codecraftai-landscaping, and the various codecraftai-interop-ext-* packages use these primitives directly.

Highlights

  • interfaces.py for enumerating local network interfaces.

  • arp.py for ARP lookups and resolution.py for name resolution helpers.

  • unicast.py, broadcast.py, and multicast.py socket-level send/receive helpers across the three delivery modes.

  • trafficcapturecontext.py providing a context-manager-based traffic capture abstraction.

  • Zero heavy third-party dependencies — intended as a reusable primitive layer.
