All 26 browser modules recompiled with define-library/import forms.
Compilation works without vm-compile-adapter (JIT pre-compilation
hangs with library wrappers in some JIT paths — skipped for now,
CEK compilation is ~34s total).
Key fixes:
- eval command: import-aware loop that handles define-library/import
locally without touching the Python bridge pipe (avoids deadlock)
- compile-modules.js: skip vm-compile-adapter, bump timeout
2621/2621 OCaml tests passing.

Core SX has zero IO — platforms extend __io-registry via (defio name
:category :data/:code/:effect ...). The server web platform declares 44
operations in web/io.sx. batchable_helpers now derived from registry
(:batchable true) instead of hardcoded list. Startup validation warns if
bound IO ops lack registry entries. Browser gets empty registry, ready
for step 5 (IO suspension).

After reusing an SSR lake element, set data-sx-lake-claimed attribute.
Subsequent dom-query uses :not([data-sx-lake-claimed]) to skip already-
reused elements, preventing SPA navigation from picking up stale lakes
from previous pages.

1. parse-trigger-spec: strip [condition] from event names, store as
"filter" modifier (e.g. keyup[key=='s'] → event="keyup", filter=...)
2. bind-event: evaluate filter conditions via JS Function constructor
when filter modifier is present
3. bind-inline-handlers: map afterSwap/beforeRequest etc. to sx:*
event names (matching what the engine dispatches)
4. bind-inline-handlers: detect JS syntax in body (contains ".") and
eval via Function instead of SX parse — enables this.reset() etc.

Tag names from dom-tag-name are lowercase (not uppercase) in the WASM
kernel — fix FORM/INPUT/SELECT/TEXTAREA comparisons in get-default-trigger.

Root cause: sx_primitives.ml registered "effect" as a native no-op (for SSR).
The bytecode compiler's (primitive? "effect") returned true, so it emitted
OP_CALL_PRIM instead of OP_GLOBAL_GET + OP_CALL. The VM's CALL_PRIM handler
found the native Nil-returning stub and never called the real effect function
from core-signals.sx.
Fix: Remove effect and register-in-scope from the primitives table. The server
overrides them via env_bind in sx_server.ml (after compilation), which doesn't
affect primitive? checks.
Also: VM CALL_PRIM now falls back to cek_call for non-NativeFn values (safety
net for any other functions that get misclassified).
15/15 source mode, 15/15 bytecode mode.

dom-id returns "" for elements without an id attribute, and "" is
truthy in SX. This caused morph-children to build spurious entries
in old-by-id keyed by "", then match unrelated children via the
empty key — advancing oi past id-keyed children like #main-content
and skipping them in cleanup.
Three changes in morph-children (engine.sx):
- old-by-id reduce: normalize empty dom-id to nil so id-less
elements are excluded from the lookup dict
- match-id binding: normalize empty dom-id to nil so new children
without ids don't spuriously match old children
- Case 2 skip condition: use (not (empty? ...)) instead of bare
(dom-id old-child) to avoid treating "" as a real id

List.find returns the element that matched, but SX some should return
the callback's truthy return value. This caused get-verb-info to return
"get" (the verb string) instead of the {method, url} dict.
Also added _active_vm tracking to VM for future HO primitive optimization,
and reverted get-verb-info to use some (no longer needs for-each workaround).

The some HO form passes callbacks through call_sx_fn which creates a new
VM that can't see the enclosing closure's captured variables (el). Replaced
with for-each + mutation which keeps everything in the same VM scope.
Also fixed destructuring param ((verb ...)) → plain param (verb).

Navigation pipeline now works end-to-end:
- outerHTML swap uses dom-replace-child instead of morph-node (morph has
a CEK continuation issue with nested for-each that needs separate fix)
- swap-dom-nodes returns the new element for outerHTML so post-swap
hydrates the correct (new) DOM, not the detached old element
- sx-render uses marker mode: islands rendered as empty span[data-sx-island]
markers, hydrated by post-swap. Prevents duplicate content from island
body expansion + SX response nav rows.
- dispose-island (singular) called on old island before morph, not just
dispose-islands-in (which only disposes sub-islands)
OCaml runtime:
- safe_eq: Dict equality checks __host_handle for DOM node identity
(js_to_value creates new Dict wrappers per call, breaking physical ==)
- contains?: same host handle check
- to_string: trampoline thunks (fixes <thunk> display)
- as_number: trampoline thunks (fixes arithmetic on leaked thunks)
DOM platform:
- 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
All 5 reactive-nav Playwright tests pass.
