Specification registry

Every protocol and format the platform implements is built from the open, publicly available specifications below — never from another project's closed source. This registry is the single place that names each specification, what the platform implements from it, and where the authoritative document lives.

Link rot is real in the packet-radio world: where the original host has vanished, the table lists the best surviving authoritative source and says so.
