Follow-up to the rename, per operator direction — the divergence is
reversed and the cut is complete:
- Host stack: boxnet (10.88.0.0/24 — a pre-rename host may still carry
claudenet on 10.87, two bridges must not claim one subnet),
box-isolate, nft tables 'inet box'/'bridge box', box-firewall.{sh,
service}. teardown-host now strips BOTH name generations, so one
script uninstalls a host of any age.
- Default template is blank: 'box new --name x' mints bare Debian;
the claude box is '--template claude'. The login hint follows the
EFFECTIVE template read off the instance, so clones of claude boxes
still get it and blank boxes are not told to run a binary they lack.
- The drill validates templates: listing, unknown-template refusal,
the allowlist rejecting BOX_NETWORK by name, and a full blank mint —
default resolves to blank, metadata stamped, box-net placement, exec
lands in 'dev', no claude binary, and isolation parity (egress +
pinned DNS) on the same contract as every template.
- drill/wipe.sh: scorched earth for drill hosts. Both tag generations,
every drill-named instance, networks/ACLs/profiles/firewall of both
generations, cached images, and (--purge-storage) the default pool.
Ends by asserting the ABSENCE of every artifact rather than trusting
the removals' exit codes.
