gates / gates (push) Successful in 27s
The internal data place, partitions as places, add_internal_place (felhom.eu architecture/16 §5-§7, §9; build B)
- internal place: the record /var/lib/felhom-agent/internal-place.json -> mounted at /mnt/belso by fs-UUID like an
  enrolled drive (startup + 20 s tick), kind "internal" in GET /disks; never takes a household drive's /mnt/belso;
  eject/decommission/format refused (dm on the system disk).
- configs/felhom-internal-place: the ruled size rule and the only lvcreate/mkfs of a system-disk volume (installer +
  the new signed op add_internal_place, operator key, no parameters).
- partitions listed per free disk (empty / filesystem / in_use); a data-bearing part's wipe id binds disk id + part
  number + fs-UUID.
- felhom-mkfs-guarded: Felhom's own sibling drive no longer blocks formatting the free part; an unlistable disk refuses.
Tests red-proved (script mutations, Go mutations, the old wrapper measured against the new tests).
