A · Acquired ​

The success response to an acquire request (A). token is a fencing token (u64, big-endian) that increases with every grant — unlike the other responses, this is the only frame that carries an 8-byte token right after the op.

Byte notation: op is an ASCII character, token is binary (u64, big-endian), and key is UTF-8 text (variable-length, shown as N in the structure). The trailing \n is 0A.
