parser.sx (3), render.sx (15), harness.sx (21), signals.sx (23),
canonical.sx (12) — 74 comments total. Each define now has a ;;
comment explaining its purpose.
Combined with the evaluator.sx commit, all 215 defines across 6 spec
files are now documented. primitives.sx and special-forms.sx already
had :doc fields.

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

WASM host-callbacks on document/body don't fire, and the CSS selector
[sx-on\:] doesn't work in the WASM query engine. Work around both
issues in sx-platform-2.js:
1. Keyboard shortcuts: global document keyup listener matches elements
by sx-trigger attribute containing key=='X', calls execute-request
via K.eval
2. sx-on: inline handlers: scan all elements for sx-on:* attributes,
bind JS Function handlers. Handle HTML attribute lowercasing
(afterSwap → afterswap) by listening for both camelCase and
lowercase event name forms
3. bind-event from: modifier resolves "body"/"document"/"window" to
direct references (dom-body, dom-document, dom-window)
4. Native SX key filter for [condition] triggers
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
1. parse-trigger-spec: strip [condition] from event names, store as
"filter" modifier
2. bind-event: native SX filter for key=='X' patterns (extracts key
char and checks event.key + not-input guard)
3. bind-event from: modifier: resolve "body"/"document"/"window" to
direct DOM references instead of dom-query
4. sx-platform-2.js: global keyboard dispatch — WASM host-callbacks
on document/body don't fire, so keyboard triggers with from:body
are handled from JS, calling execute-request via K.eval
5. bind-inline-handlers: map afterSwap/beforeRequest to sx: prefix,
eval JS bodies via Function constructor
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

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.

The OCaml render-to-sx wrapper now correctly overrides the SX version
loaded from adapter-sx.sx: string inputs get parsed → aser evaluated,
AST inputs delegate to the SX version. Fixes ~41 aser test failures.

- cek-call/cek-run: dispatch through Sx_ref.cek_call for signal tests
- context: registered as both env binding and Sx_primitives primitive
so signals.sx can resolve it through the primitive table
- forms.sx: loaded before other web modules — provides defpage special
form, stream-chunk-id, normalize-binding-key, etc.
- regex-find-all: substring-based stub for component scanning
- now-ms: stub returning 1000

79 occurrences renamed to match the actual function name in
adapter-sx.sx. Tests still fail because render-to-sx takes an
AST expression, not a source string — needs eval-string wrapper.

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.

The ~geography/scopes-demo-example component had (&key demo code), and
its body used (code code) — the parameter shadowed the HTML tag, causing
"Undefined symbol: code" at render time. Renamed to (&key demo src).

The poll trigger in bind-triggers called set-interval but discarded the
interval ID, so polls continued firing after the element was removed from
the DOM. Now the callback checks el.isConnected each tick and self-clears
when the element is gone (HTMX-style cleanup).

highlight returns (code (span ...)) elements which render-to-html
handles but aser doesn't. OOB responses go through aser. Plain text
for now — highlighting needs to happen client-side or aser needs
HTML tag support.

Now calls (highlight text) to produce syntax-colored SX output.
OCaml-side aser has full env so code/span tags resolve correctly.

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.

aser in SX doesn't have access to helper/now/state-get. eval-expr
evaluates the body in the current env, returns the AST. The OCaml
handler interception then calls aser server-side with the full env.

Handler closure env didn't have HTML tags (code, span, div etc.)
causing Undefined symbol errors. aser without explicit env uses
the global env which has all tags registered.
Also reverts oob-code highlight change (code tag not available in
aser context).

Keywords were printed as strings because list treated :path as kwargs.

Both used (env-get name) with one arg which always returned nil.
Now use eval-expr + make-symbol with cek-try fallback, same pattern
as the handler dispatch.

Handler bodies contain HTML elements (div, p, span) which need the
render pipeline. eval-expr treats them as function calls. aser
evaluates and serializes HTML to wire format.

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.

env-get requires (env-get env name) with two args but dispatch.sx
was calling it with one arg, always returning nil. Now uses
eval-expr + make-symbol to resolve the handler binding in the
current env, with cek-try fallback to nil.

api and call-handler now use (error ...) for not-found and method
mismatch, so error boundaries catch them properly instead of
rendering error messages as page content.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

Comprehensive interaction tests covering GET handlers (click-to-load,
tabs, polling, search, filter, keyboard, lazy-load), POST handlers
(form-submission, inline-validation, reset), mutation handlers
(delete-row, edit-row, inline-edit, bulk-update, put-patch), and
special handlers (dialogs, oob-swaps, animations, progress-bar, retry,
json-encoding, vals-and-headers).
Tests use trackErrors + waitForSxReady. Will pass once server is
restarted with request primitives and handler dispatch.

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
