One name per thing, per the HQ glossary: the module/container/image/binary/repo becomes mesh-controller, the seat the-controller, and the store+broker pair the foundation (embedded base bundles, default template and example lock renamed with their go:embed directives). No behaviour change — a pure vocabulary rename. Claude-Session: https://claude.ai/code/session_01D6qtiYU3P9jk3pnAXyAFyx
