Swap Werkzeug for Caddy as the protocol layer for http and https decoy services. Flask keeps owning app logic (fake_app, custom_body, headers, syslog) on 127.0.0.1:8080; Caddy terminates h1/h2/h2c/h3 on the wire with real-world TLS/QUIC fingerprints. - Add `multi_enum` FieldType to ServiceConfigField + _coerce - Add `http_versions` field to HTTPService (h1/h2c) and HTTPSService (h1/h2/h3); selecting h3 emits UDP/443 port mapping in compose - Rewrite both Dockerfiles with multi-stage Caddy binary copy + setcap for port binding as the logrelay user - Entrypoints parse HTTP_VERSIONS JSON, render a Caddyfile, start Flask in background, wait for it, then exec Caddy - https/server.py drops direct TLS handling; Caddy owns the cert - Add ProxyFix to both server.py so Flask sees real attacker IPs - Frontend: multi_enum checkbox-group renderer in ServiceConfigFields; FormValue union extended to string[]; compactPayload skips [] - Fix stale test_smtp_relay_schema_matches_smtp: relay schema is a superset of smtp, not equal; update assertions accordingly
