- wasm_of_ocaml compiles OCaml SX engine to WASM (722/722 spec tests) - js_of_ocaml fallback also working (722/722 spec tests) - Thin JS platform layer (sx-platform.js) with ~80 DOM/browser natives - Lambda callback bridge: SX lambdas callable from JS via handle table - Side-channel pattern bypasses js_of_ocaml return-value property stripping - Web adapters (signals, deps, router, adapter-html) load as SX source - Render mode dispatch: HTML tags + fragments route to OCaml renderer - Island/component accessors handle both Component and Island types - Dict-based signal support (signals.sx creates dicts, not native Signal) - Scope stack implementation (collect!/collected/emit!/emitted/context) - Bundle script embeds web adapters + WASM loader + platform layer - SX_USE_WASM env var toggles WASM engine in dev/production - Bootstrap extended: --web flag transpiles web adapters, :effects stripping Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
