Lazy module loading (Step 5 piece 6 completion): - Add define-library wrappers + import declarations to 13 source .sx files - compile-modules.js generates module-manifest.json with dependency graph - compile-modules.js strips define-library/import before bytecode compilation (VM doesn't handle these as special forms) - sx-platform.js replaces hardcoded 24-file loadWebStack() with manifest-driven recursive loader — only downloads modules the page needs - Result: 12 modules loaded (was 24), zero errors, zero warnings - Fallback to full load if manifest missing VM transpilation prep (Step 6b): - Refactor lib/vm.sx: 20 accessor functions replace raw dict access - Factor out collect-n-from-stack, collect-n-pairs, pad-n-nils helpers - bootstrap_vm.py: transpiles 9 VM logic functions to OCaml - sx_vm_ref.ml: proof that vm.sx transpiles (preamble has stubs) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
