spec/ now contains only the language definition (5 files): evaluator.sx, parser.sx, primitives.sx, render.sx, special-forms.sx lib/ contains code written IN the language (8 files): stdlib.sx, types.sx, freeze.sx, content.sx, bytecode.sx, compiler.sx, vm.sx, callcc.sx Test files follow source: spec/tests/ for core language tests, lib/tests/ for library tests (continuations, freeze, types, vm). Updated all consumers: - JS/Python/OCaml bootstrappers: added lib/ to source search paths - OCaml bridge: spec_dir for parser/render, lib_dir for compiler/freeze - JS test runner: scans spec/tests/ (always) + lib/tests/ (--full) - OCaml test runner: scans spec/tests/, lib tests via explicit request - Docker dev mounts: added ./lib:/app/lib:ro Tests: 1041 JS standard, 1322 JS full, 1101 OCaml — all pass Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
