Self-hosted deployments already terminate TLS at Caddy/Traefik/nginx; making the server do TLS too means double cert config, dual ACME plumbing, and an untested code path. Drop RM_TLS_CERT/RM_TLS_KEY, remove TLSEnabled() and the ListenAndServeTLS branch. Replace the cookie's "Secure if TLS-in-process" check with a new RM_COOKIE_SECURE flag (default true). Local HTTP-only testing sets RM_COOKIE_SECURE=false; production is always behind a TLS proxy and the cookie stays Secure. Default port :8443 → :8080. docker-compose binds 127.0.0.1 only and populates RM_TRUSTED_PROXY. spec.md §4.1/§10.1 rewritten with a Caddyfile snippet and a hard "do not expose RM_LISTEN publicly" warning. enrollResponse keeps cert_pin_sha256 in the shape but the server can't introspect a cert it doesn't terminate — operator pastes the proxy's hash into -cert-pin at install time.
