Step 5p6 lazy loading + Step 6b VM transpilation prep
...
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)

Fix WASM browser: broken links (&rest bytecode) + broken reactive counter (ListRef mutation)
...
Two bugs fixed:
1. Links: bytecode compiler doesn't handle &rest params — treats them as
positional, so (first rest) gets a raw string instead of a list.
Replaced &rest with explicit optional params in all bytecode-compiled
web SX files (dom-query, dom-add-listener, browser-push-state, etc.).
The VM already pads missing args with Nil.
2. Reactive counter: signal-remove-sub! used (filter ...) which returns
immutable List, but signal-add-sub! uses (append!) which only mutates
ListRef. Subscribers silently vanished after first effect re-run.
Fixed by adding remove! primitive that mutates ListRef in-place.
Also:
- Added evalVM API to WASM kernel (compile + run through bytecode VM)
- Added scope tracing (scope-push!/pop!/peek/context instrumentation)
- Added Playwright reactive mode for debugging island signal/DOM state
- Replaced cek-call with direct calls in core-signals.sx effect/computed
- Recompiled all 23 bytecode modules

OCaml VM browser: safe equality, thunk trampolining, platform functions, nav pipeline
...
Core runtime fixes:
- Safe equality (=, !=): physical equality for dicts/lambdas/signals,
structural only for acyclic types. Prevents infinite loops on circular
signal subscriber chains.
- contains?: same safe comparison (physical first, structural for simple types)
- Thunk trampolining in as_number and to_string: leaked thunks auto-resolve
instead of showing <thunk> or erroring "Expected number, got thunk"
- Diagnostic first error: shows actual type received
Island hydration fixes:
- adapter-dom.sx: skip scope-emit for spreads inside islands (was tripling classes)
- schedule-idle: wrap callback to absorb requestIdleCallback deadline arg
- home-stepper: remove spread-specific highlighting (all tokens same style per step)
Platform functions (boot-helpers.sx):
- fetch-request: 3-arg interface (config, success-fn, error-fn) with promise chain
- build-request-body: form serialization for GET/POST
- strip-component-scripts / extract-response-css: SX text processing
- Navigation: bind-boost-link, bind-client-route-click via execute-request
- Loading state: show-indicator, disable-elements, clear-loading-state
- DOM extras: dom-remove, dom-attr-list (name/value pairs), dom-child-list (SX list),
dom-is-active-element?, dom-is-input-element?, dom-is-child-of?, dom-on,
dom-parse-html-document, dom-body-inner-html, create-script-clone
- All remaining stubs: csrf-token, loaded-component-names, observe-intersection,
event-source-connect/listen, with-transition, cross-origin?, etc.
Navigation pipeline:
- browser-push-state/replace-state: accept 1-arg (URL only) or 3-arg
- boot.sx: wire popstate listener to handle-popstate
- URL updates working via handle-history + pushState fix
Morph debugging (WIP):
- dom-child-list returns proper SX list (was JS Array)
- dom-query accepts optional root element for scoped queries
- Navigation fetches and renders SX responses, URL updates, but morph
doesn't replace content div (investigating dom-child-list on new elements)
