alh477/dcf-python repository overview

⁠alh477/dcf-python — DCF mesh node (Python)

The DCF / HydraMesh Python mesh endpoint (a2a over DcfTextNode). It carries the certified 17-byte DeModFrame as bare frames batched into 32-byte SuperPacks over UDP, with a frequency-channel rendezvous on the frame dst. It meshes with alh477/dcf-nodejs (the same bare-frame + SuperPack dialect).

Built hermetically with Nix (dockerTools). Entrypoint a2a.py; default command recv --follow.

⁠Run

# a persistent listener on a channel
docker run --rm -p 7801:7801/udp alh477/dcf-python recv --follow --channel duet --port 7801

# unicast a message to peers
docker run --rm alh477/dcf-python send "hello" --channel duet --peers HOST:7801

⁠Wire

• Quantum: 17-byte DeModFrame (version 1), CRC-16/CCITT-FALSE — certified, shared across SDKs.
• Transport: bare DeModFrame text frames batched into SuperPacks (34→32 bytes/pair) over UDP. Meshes with alh477/dcf-nodejs. (The Go/Rust/C nodes use a different ProtoMessage envelope.)
• Adapter: DCF-Text L2 framing (certified) + SuperPack (certified).
