- New Corefile snippet (common) shared across plain DNS / DoT / DoH so zone-loading + forward + cache stay DRY across all three transports - scripts/generate-certs.sh: openssl-only self-signed RSA cert with SANs for localhost / 127.0.0.1 / ::1 / coredns / dns.local. Idempotent — skips regeneration if cert is valid >24h ahead; FORCE=1 to rotate. - Key chmod is 0644 so the CoreDNS container's nonroot user can read it via the bind mount. Acceptable for local dev; production should mount real certs with proper UID/GID. - DOT_PORT=8853, DOH_PORT=8443 (avoids Caddy already-on-443 collision) - Makefile: `make certs`, `make test-tls` - All three transports verified end-to-end (dig +tls, dig +https, curl with raw RFC 8484 wire format)
