Put back by hand, it was found afresh and its copy became the hold's original, so a machine that
kept restoring it kept growing copies and lost which one was first. The first original now stays
the record's, content that differs is kept once beside it, and the note says a rollback means
unassigning the private network. Nothing is removed unless it is <wireguard dir>/<iface>.conf,
not a path the mesh writes, and not a link, which would leave the key-bearing target behind.
Kept on disk it was the take's fallback; once the mesh's interface is up in its place and a peer
has handshaken with it, it is an unmaintained way back onto the network, held for ever. It is now
removed from where its unit reads it, its kept original verified first and left as it is, and the
hold ends. Until proven — no handshake, or wg not answering — it is kept and the report says why.
The retirement is recorded apart from holds, so later applies, an undeclare, and a reassignment
find it retired rather than missing, and nothing writes it back.
