- Declarative config_schema on RDP, Telnet, MySQL, Redis, SMTP, SMTP_Relay matching the keys each service already reads at compose time. - TODO marker on the 19 services that accept service_cfg but never read it, so future contributors know where to plug schemas in. - Wizard base64-wraps all textarea values at INI emit (DeckyFleet buildIni); validate_cfg detects the b64: sentinel and decodes back to UTF-8. Plain raw strings still pass through for direct API submitters. - HTTPS image entrypoint accepts PEM content or path in TLS_CERT/TLS_KEY: detects a BEGIN header, writes content to /opt/tls/, and re-exports the on-disk path so server.py keeps reading paths. - Tests cover schema/compose alignment for each new service plus textarea base64 round-trip (incl. UTF-8) and HTTPS PEM end-to-end.
