The old tmux check hardcoded blank/claude/codex/grok, so a new template
could ship without CI ever reading it. The suite now discovers templates/*/
and, for each: drives the REAL load_template (extracted from bin/box, the
same trick box_tier and install.sh's DEST block get) so box.env must parse
against the actual allowlist with BOX_IMAGE + BOX_USER present; asserts
user-data.yaml exists, declares #cloud-config, and is well-formed YAML
(python3+pyyaml, skipped loudly where absent — CI has both); and keeps the
#65 tmux contract. Fixtures prove the dies a green parse cannot: an unknown
key (no template grows a network) and a missing required key.
Staging-specific: both boot demands proven through the parser, docker + rig
preinstalled, and a creds-free refusal grep — no tailscale/authkey/ssh in
effective cloud-init lines; rig installs those inside the guest. Plus the
cmd_new half, grepped the way the expose guard is: the REQUIRE_VM refusal
orders after pick_mode, and boot.autostart is stamped only under the
T_AUTOSTART guard.
