A worked example for one device: the bytes it sends and the ACKs it gets (any member)

Everything needed to write sender firmware for THIS device: a sample payload, a sample nonce of its own width, the resulting datagram in hex, the ACK for each status, and a field-by-field byte-offset table for both directions. The nonce and payload are samples and are labeled as such — nonce_note says what the device must send instead, which for every keyed suite is a value that NEVER repeats under its key. Everything else is the device's real row, so the datagram is byte for byte what it would put on the wire. The key is used to compute this and is never returned: it existed once, in the create response.
