Hexagonal architecture
@v12/core declares ports and imports no infrastructure. Every external

if that ever stops being true.

@v12/core declares ports and imports no infrastructure. Every external

A versioned manifest compiles into a LangGraph graph. Models are referenced by alias, never by id — retargeting a vertical onto a different model is a row update.
Zero any, branded ids, exhaustive unions, Result for expected
failures. The frontend imports the same Zod schemas the API validates with.
