incus-user confines an incus-group user to their own project, but its
defaults miss box's contract three measured ways (Debian 13 / Incus 6.0.4):
a private UNHARDENED NAT bridge per user (ipv6.nat=true, no ACL, no DNS
isolation), snapshots blocked, and the box-net profile invisible to their
project. So the tier is an admin-run idempotent convergence:
box grant <user> # incus group; touch incus-user (the project is lazy);
# drop the private-bridge eth0 from their default
# profile; restricted.networks.access=boxnet — and ONLY
# boxnet, or the unhardened bridge stays one --network
# flag away; restricted.snapshots=allow; install the
# shipped box-net profile into their project
box revoke <user> # group removal closes the socket, boxes keep running
--purge # ...or delete their world, and assert the absence
box_tier() (live credentials, argless id -nG; byte-identical copy in
setup-host.sh) drives the tier-aware surface: new pre-flights the profile
and names the right fix per tier, expose refuses before any daemon call
(without the guard the failure is a lie — restricted certs cannot read
boxnet's redacted config, so box_net_ip claims a running box has no
address), setup-host exits 0 with the honest note, doctor judges only what
the caller can see.
Also fixed while the rehearsal exercised the lifecycle: box restore
dispatched 'incus restore', which does not exist in Incus 6 (it is
'incus snapshot restore') — the verb had never worked. Fixed for every tier.
Convergence survives incus-user restarts by that tool's own design (it
configures a project only at creation) — read in its source, then measured.
