Codex was right on all three, and the first was a design error on my part: the
checkout is bind-mounted into every container, so 'git merge' swaps the running
code instantly — 'migrations before traffic' was not achievable by ordering.
The updater now goes down → merge → dependencies → migrate → assets → restart →
up, trading a short deliberate outage for never serving code whose schema does
not exist yet. If a step fails the site STAYS down: coming back up with new code
on an old schema is worse than staying dark until someone looks.
It also records the last successfully deployed commit. A run that died halfway
left the checkout ahead, so the next run said 'already up to date' and skipped
the rest forever.
And it installs dependencies when a lockfile moved: vendor/ and node_modules/
live in the bind mount and shadow the image, so rebuilding the image never
updated them — migrations could run against stale packages.

install.sh sets up a bare Debian/Ubuntu server end to end: Docker, git,
WireGuard, clone, generated secrets, stack, migrations, hub keypair, the Owner
account and a closed firewall. Re-runnable: it keeps an existing .env and never
regenerates the hub key, which would disconnect every onboarded host.
update.sh pulls and applies. Migrations run before the new containers take
traffic, the image is rebuilt only when its definition changed, and the queue
workers are restarted — they are long-running processes that otherwise keep the
old classes in memory, which cost us an hour during development.
clupilot:create-admin creates or promotes an Owner, so re-running the installer
fixes a lost role instead of failing on a taken address.
