+The implementation language is Go, decided in [RFC 0001](docs/rfcs/0001-implementation-language.md).

 It must stay self-contained: no imports from Werkator code, no Gradle coupling to the Werkator build.
 The roadmap is session B of [docs/plan/21-werkdock-extraction-and-webspace-install.md](../docs/plan/21-werkdock-extraction-and-webspace-install.md).
