The availability-critical subsystem: no-self-signed-path (Twilio 31910),
the /data-loss -> LE 5/week duplicate-cert lockout -> total-inbound-outage
chain (31910 streams + 11237 webhooks) with backup command; HTTP-01 vs
DNS-01 (bundled plugin set: cloudflare/route53/porkbun/hetzner/desec,
duckdns excluded) vs BYO-cert rustls Phase 1 (RUTSTER_TLS_CERT/KEY,
hot-reload); Caddy renewal-vs-reload distinction with the #6420/#7222
caveat; fleet patterns (central wildcard vs per-node certs) with the
identical-wildcard trap and the on-demand-TLS rejection.
