// The Protobuf Transport Adapter Shared By The Host Runtime And Sidecars.

// Domain messages stay codec-free: each carries its canonical Postcard value
// and its described shape. This module projects every such message onto the
// protobuf form packaging publishes, so no per-type protobuf code is generated.
