The "behind an existing Caddy" section assumed the DNS plugin was being set up
from scratch. The realistic case is a box whose Caddy already does Cloudflare
DNS-01 for another domain, so it now covers that: set acme_dns once globally and
every site inherits it, or scope a token per zone with a snippet.
Leads with the failure that will actually happen -- a Cloudflare token is scoped to
named zones, so the existing one grants DNS:Edit on the domain it was made for and
nothing else, and the new site fails its challenge on a permissions error whose
text does not say so.
Also spells out that *.test.rosterchief.app does NOT match test.rosterchief.app: a
wildcard covers exactly one label, so leaving the bare host off the site line gives
the club subdomains a certificate and the control panel none.

Closes every club subdomain with a 503 in that club's own colours, stands the
scheduled jobs down, and keeps open exactly what is needed to end it again.
The exemptions ARE the feature:
- /accounts/ stays open on the base domain. Close it too and you cannot sign in to
turn maintenance off -- a lock-down with no key, fixable only from a shell.
- /healthz answers on every host. Close it and the load balancer decides the node
is dead, stops routing to it, and takes the control panel down with everything
else.
- migrate and collectstatic are NOT blocked. Maintenance is usually declared in
order to run them; a blanket guard on BaseCommand would mean turning the mode off
to do the work you turned it on for. Only the domain jobs (archive_overdue_clubs,
extend_event_series, import_members_csv) refuse, and they exit non-zero so cron
mails you -- a scheduled job that silently skips itself is how a month of billing
goes missing.
The state is cached with a 10-second TTL, not for ever. Write-through makes the
flip instant for the shared Redis of a real deployment, and the TTL is the belt to
that braces: on a per-process cache -- a dev box with no Redis, or a misconfigured
deploy -- a lock-down that reached only one gunicorn worker would be worse than
useless. Live-verified: a club subdomain, its login page and the base domain all
503 while the control panel and the sign-in screens stay up.
Also adds the two deployment pieces asked for: compose.behind-proxy.yaml for a
dev/test box that already runs Caddy on :80 (app on the loopback, host Caddy proxies
to it -- and the host's Caddy still needs the DNS plugin, because the wildcard is
still a wildcard), and deploy/backup.sh + restore-check.sh with a cron schedule. The
backup writes to a .part file and only lands it once gzip -t says it is readable: a
truncated dump that looks like a backup is the failure you find on the day you need
it. The weekly restore rehearsal is the only line in that cron that proves the rest
work.

/healthz checks the database and does a cache ROUND TRIP, not a ping. Both matter:
a node that cannot reach Postgres serves nothing, and a cache that accepts writes
and returns nothing would have waffle read every feature flag as unset -- so
"healthy" has to mean more than "the process is listening", or the load balancer
will keep feeding traffic to a node that only looks alive.
No auth and no tenant on it: the proxy, and later a load balancer, must reach it on
any host.
DEPLOYMENT.md is the runbook, and leads with the five things that make this app not
a generic Django deploy: the wildcard cert forces DNS-01 (Let's Encrypt will not
issue a wildcard over HTTP-01); Redis is required on one server, not two, because
of the per-process flag cache; SECURE_PROXY_SSL_HEADER plus Caddy's
X-Forwarded-Proto or WebAuthn and the SSL redirect both break; uploads must reach
object storage BEFORE the second app server, not during; and invoices need native
pango.
Also documents why the archive job ships with --commit off, why migrations are run
explicitly rather than from the entrypoint, and how to test the restore before the
day you need it.
