All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 4m49s
Three-layer architecture:
spec/ — Core language (19 files): evaluator, parser, primitives,
CEK machine, types, continuations. Host-independent.
web/ — Web framework (20 files): signals, adapters, engine,
orchestration, boot, router, CSSX. Built on core spec.
sx/ — Application (sx-docs website). Built on web framework.
Split boundary.sx into boundary-core.sx (type-of, make-env, identical?)
and boundary-web.sx (IO primitives, signals, spreads, page helpers).
Bootstrappers search spec/ → web/ → shared/sx/ref/ for .sx files.
Original files remain in shared/sx/ref/ as fallback during transition.
All 63 tests pass.
