Measured live on the first e2e mint: cloud-init runs runcmd as root but
with NO $HOME in the environment, and rig's installer (set -u) reads
$HOME for its DEST — the mint died with 'HOME: unbound variable'. The
seed line now pins HOME=/root explicitly, with the scar documented next
to it in every tenant template.

The tenant content that lived in claude/codex/grok's cloud-init — agent CLI
installs, docker, node, the per-template agent-context heredocs — moves to
rig's bootstrap roles (rig#31), where it is convergent, idempotent and
testable end to end. What remains per template is a thin seed: the tenant
user, tmux (#65), and rig preinstalled — nothing that joins a tailnet or
admits credentials.
- BOX_BOOTSTRAP_ROLE: a template names the creds-free rig role cmd_new
auto-runs inside the guest after cloud-init settles. The value is a role
NAME by allowlist — anything shell-shaped dies at parse time, on the
host. A failed role leaves the box up and names the re-run.
- render_userdata: the seed's ONE substitution. @RIG_REPO@/@RIG_REF@
resolve from the mint environment (default heavy-duty/rig @ main —
unpinned, the honest rig#29 treatment, until rig#32's releases); values
are whole-string-validated before touching the YAML, because they land
inside a runcmd shell line.
- templates/staging: the re-cut of #69's layering — user ops,
BOX_REQUIRE_VM=1, BOX_AUTOSTART=1, role staging. The tailnet workload
join holds a key and stays operator-run; cmd_new prints it as the next
step and box never sees the key.
- blank stays a box with nobody home: no rig, no role, nothing auto-runs.
