pack-size 64 MiB (object count vs prune amplification), split repos
for index RAM, cache on /backup, read-concurrency vs the seek-bound
walk, nextcloud preview excludes, ARC floor before seeding, weekly
rotating read-data-subset verification, and the analysis of a full
plakar->restic migration (conclusion: the split is a reasonable end
state, gated on PlakarKorp/plakar#2338).

Per-file access to cold, tiny-file trees on HDD is ~275 IOPS whatever
the importer; only zfs send reads sequentially. Options recorded,
direction: per-file for the 16 small instances, zfs send for
nextcloud/seafile.

- status: S3 kloset seeded, restore-tested, nightly cron installed
- restore-test paths moved off /tmp — it is a 16G tmpfs on ks4 and the
10 GiB dumps restore sat in RAM squeezing the ZFS ARC
- seafile-fs note rewritten: cause unknown, local-kloset bisect next;
nextcloud 3-4h/night cost tracked for the upstream growth issue

Seafile's block store wedged the fs walker for 12h in an lstat
preemption/EINTR livelock on the live pool; coverage moves to the
incus leg reading the sdb replica. Restore test + cron are the
remaining steps of the data leg.

README with instance tables and nuc<->ks4 network flow chart;
per-container install/troubleshooting docs for nuc (jellyfin
server/client, transmission-bt, bare-metal reinstall) and the
ks4 two-leg backup scheme (incus-copy over wireguard).
