- Parse Cookie header in OCaml HTTP server for get-cookie primitive
- Stepper saves step-idx to cookie via host-set! FFI on click
- Stepper restores from cookie: get-cookie on server, host-get FFI on client
- Cache key includes stepper cookie value to avoid stale SSR
- registerNative: also update Sx_primitives table for CALL_PRIM dispatch

Root cause: process-elements during WASM boot-init marks elements as
processed but process-one silently fails (effect functions don't execute
in WASM boot context). Deferred process-elements then skips them.
Fixes:
- boot-init: defer process-elements via set-timeout 0
- hydrate-island: defer process-elements via set-timeout 0
- process-elements: move mark-processed! after process-one so failed
boot-context calls don't poison the flag
- observe-intersection: native JS platform function (K.registerNative)
to avoid bytecode callback issue with IntersectionObserver
- Remove SX observe-intersection from boot-helpers.sx (was overriding
the working native version)

Fix 3 OCaml bugs that caused spec explorer to hang:
- sx_types: inspect outputs quoted string for SxExpr (not bare symbol)
- sx_primitives: serialize/to_string extract SxExpr/RawHTML content
- sx_render: handle SxExpr in both render-to-html paths
Restructure spec explorer for performance:
- Lightweight overview: name + kind only (was full source for 141 defs)
- Drill-in detail: click definition → params, effects, signature
- explore() page function accepts optional second arg for drill-in
- spec() passes through non-string slugs from nested routing
Fix aser map result wrapping:
- aser-special map now wraps results in fragment (<> ...) via aser-fragment
- Prevents ((div ...) (div ...)) nested lists that caused client "Not callable"
5 Playwright tests: overview load, no errors, SPA nav, drill-in detail+params

The slug extractor after (api. scanned for the first ) but for nested
URLs like (api.(delete.1)) it got "(delete.1" instead of "delete".
Now handles nested parens: extracts handler name and injects path
params into query string. Also strengthened the Playwright test to
accept confirm dialogs and assert strict row count decrease.

- cek-call/cek-run: dispatch through Sx_ref.cek_call for signal tests

Three fixes in run_tests.ml defhandler parser:
1. Extract &key param names, store in hdef["params"]. run-handler
binds them from mock args before evaluating — fixes row-editing,
tabs, inline-edit, profile-editing handlers.
2. Capture all body forms after params, wrap in (do ...) when
multiple — fixes ex-slow (sleep before let).
3. Register all HTML tags as native fns via Sx_render.html_tags —
fixes ex-bulk (tr tag), and enables aser to serialize any tag.

Skip the SX api function entirely. The OCaml handler interception
looks up handler:ex-{slug} in the env, extracts the body, and calls
aser directly with the full global env. This avoids the double-eval
problem where eval-expr evaluates HTML tags as function calls and
then tries to call the result.

defhandler was only available via web-forms.sx which had load
dependencies that failed. Now registered as a native special form
in make_server_env, works in both coroutine and HTTP modes.
Key fix: custom special forms receive [List args; Env eval_env],
not flat args. The handler is now bound in the eval env, not the
make_server_env closure env.

Paths containing (api.) are intercepted before page routing and
dispatched directly to the api function. The handler result is
rendered to SX wire format and returned without layout wrapping.
This fixes the issue where handler URLs went through page routing,
causing the handler result to be passed as a slug to the page
function, and the response to be wrapped in the full page layout.

OCaml server:
- Accept POST/PUT/PATCH/DELETE for /sx/ paths (was GET-only)
- Parse request body, query string, set per-request context
- Add 16 request primitives: now, state-get/set!, request-form/arg,
request-json, request-header(s), request-method/body, into, etc.
- URL-encoded body parser for form submissions
Handler dispatch (sx/sx/handlers/dispatch.sx):
- `api` function routes URL paths like (api "click") to handler:ex-click
- `call-handler` checks HTTP method, binds params, evaluates body
- Handlers defined via defhandler in handlers/examples.sx now reachable

Route errors and missing pages now show a styled error message inside
the normal layout (header, nav still work) instead of bare "nil" text

highlight.sx now returns a list of (span :class "..." "text") elements
instead of a string. The rendering pipeline handles the rest:
- Server render-to-html: produces <span class="...">text</span>
- Client render-to-dom: produces DOM span elements
- Aser: serializes spans as SX for client rendering
Key fixes:
- hl-span uses (make-keyword "class") not :class (keywords evaluate
to strings in list context)
- render-sx-tokens returns flat list of spans (no wrapper)
- hl-escape is identity (no escaping needed for tree values)
- highlight.sx added to browser bundle + platform loader
- ~docs/code renders src directly as child of pre

- Add missing ./sx/sxc:/app/sxc:ro volume mount to dev-sx compose —
container was using stale image copy of docs.sx where ~docs/code had

attrs are preserved during render-to-dom

call_lambda returns a thunk (for TCO) but sf_named_let was passing
it directly to the CEK machine without trampolining. The loop body
never executed — set! mutations were lost and the loop returned
immediately.
One-line fix: wrap call_lambda result in trampoline.
All 87 Node tests now pass:
- test-named-let-set.js: 9/9 (was 3/9)
- test-highlight.js: 7/7 (was 1/7)
- test-smoke.js: 19/19
- test-reactive-islands.sx: 22/22
- test-reactive-islands.js: 39/39
Note: server-side source display still empty because the JIT
compiler handles named let differently (VM bytecode path, not
tree-walk). The JIT fix is separate.

component-source from data/helpers.sx was overriding the native
OCaml version. The SX version calls env-get with wrong arity (1 arg
vs required 2), producing empty source. Re-bind the native version
in SSR overrides after file loading.
Note: source code still not visible because highlight function
returns empty — separate issue in the aser rendering pipeline.
Also adds:
- spec/tests/test-reactive-islands.sx — 22 SX-native tests for all

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).

reactive-spread (module-loaded via K.load) doesn't apply CSSX classes
to DOM elements. Returns null instead of "sx-text-center". This is the
root cause of hydration stripping all styling — every rendering function

12 pass, 1 fail — the reactive-spread test is the blocker.

Three root causes for reactive attribute updates not propagating in WASM:
1. `context` CEK special form only searched kont provide frames, missing
`scope-push!` entries in the native scope_stacks hashtable. Unified by
adding scope_stacks fallback to step_sf_context.
2. `flush-subscribers` used bare `(sub)` call which failed to invoke
complex closures in for-each HO callbacks. Changed to `(cek-call sub nil)`.
3. Test eagerly evaluated `(deref s)` before render-to-dom saw it.
Fixed tests to use quoted expressions matching real browser boot.
WASM native: 10/10, WASM shell: 26/26.

Revert (when (client?) ...) guard in signals.sx — it broke JS tests
since client? is false in Node.js too.
Instead, rebind effect and register-in-scope as no-ops in sx_server.ml
AFTER all .sx files load. The SX definition from signals.sx is replaced
only in the OCaml SSR context. JS tests and WASM browser keep the real
effect implementation.
Remove redundant browser primitive stubs from sx_primitives.ml — only
resource SSR stub needed (effect override moved to server setup).
JS tests: 1582/1585 (3 VM closure interop remain)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- signals.sx: guard effect body with (when (client?) ...) so effects

- sx_primitives.ml: add resource SSR stub (returns signal {loading: true}),
remove 27 unnecessary browser primitive stubs
- sx_server.ml: native component-source that looks up Component/Island
from env and pretty-prints the definition (replaces broken Python helper)
- reactive-islands/index.sx: Examples section with all 15 live demos

Registering map/for-each/reduce as PRIMITIVES caused the compiler to
emit CALL_PRIM for them everywhere. The OCaml VM's call-primitive
can't invoke VM closures, causing "Undefined symbol: resource" crashes.
Revert vm.sx to original CALL_PRIM handler. Remove map/for-each/reduce
from JS PRIMITIVES so compiler emits OP_CALL instead (handled by
vm-call which dispatches correctly).
3 JS VM tests remain failing (VM closure interop) but production is stable.

signal-add-sub! used (append! subscribers f) which returns a new list
for immutable List but discards the result — after signal-remove-sub!

JIT compiler:
- Fix jit_compile_lambda: resolve `compile` via symbol lookup in env
instead of embedding VmClosure in AST (CEK dispatches differently)
- Register eval-defcomp/eval-defisland/eval-defmacro runtime helpers
in browser kernel for bytecoded defcomp forms
- Disable broken .sxbc.json path (missing arity in nested code blocks),
use .sxbc text format only
- Mark JIT-failed closures as sentinel to stop retrying
CSSX in browser:
- Add cssx.sx symlink + cssx.sxbc to browser web stack
- Add flush-cssx! to orchestration.sx post-swap for SPA nav
- Add cssx.sx to compile-modules.js and mcp_tree.ml bytecode lists
SPA navigation:
- Fix double-fetch: check e.defaultPrevented in click delegation
(bind-event already handled the click)
- Fix layout destruction: change nav links from outerHTML to innerHTML
swap (outerHTML destroyed #main-panel when response lacked it)
- Guard JS popstate handler when SX engine is booted
- Rename sx-platform.js → sx-platform-2.js to bust immutable cache
Playwright tests:
- Add trackErrors() helper to all test specs
- Add SPA DOM comparison test (SPA nav vs fresh load)
- Add single-fetch + no-duplicate-elements test
- Improve MCP tool output: show failure details and error messages

Root cause: _env_bind_hook mirrored ALL env_bind calls (including
lambda parameter bindings) to the shared VM globals table. Factory
functions like make-page-fn that return closures capturing different
values for the same param names (default-name, prefix, suffix) would
have the last call's values overwrite all previous closures' captured
state in globals. OP_GLOBAL_GET reads globals first, so all closures
returned the last factory call's values.
Fix: only sync root-env bindings (parent=None) to VM globals. Lambda
parameter bindings stay in their local env, found via vm_closure_env
fallback in OP_GLOBAL_GET.
Also in this commit:
- OP_CLOSURE propagates parent vm_closure_env to child closures
- Remove JIT globals injection (closure vars found via env chain)
- sx_server.ml: SX-Request header → returns text/sx (aser only)
- sx_server.ml: diagnostic endpoint GET /sx/_debug/{env,eval,route}
- sx_server.ml: page helper stubs for deep page rendering
- sx_server.ml: skip client-libs/ dir (browser-only definitions)
- adapter-html.sx: unknown components → HTML comment (not error)
- sx-platform.js: .sxbc fallback loader for bytecode modules
- Delete sx_http.ml (standalone HTTP server, unused)
- Delete stale .sxbc.json files (arity=0 bug, replaced by .sxbc)
- 7 new closure isolation tests in test-closure-isolation.sx
- mcp_tree.ml: emit arity + upvalue-count in .sxbc.json output

Sx_compiler.compile/compile_module now emit arity (local slot count) in

VM allocated only 16 local slots per module frame.
