Sources

Every outside source this knowledge base rests on, with a link. Manufacturer manuals are linked, never copied: get them from the manufacturer. Short paraphrases with page numbers appear in the pages that use them; nothing longer.

A³’s own sources (its decisions, reviews and measurements) are named on the page where they are used, with a date.

• prolink-connect (protocol documentation and implementation): https://github.com/EvanPurkhiser/prolink-connect

• beat-link (EPL-2.0) and dysentery (EPL-1.0) are reference implementations; A³ reads their documentation and never ports their code.
