Add MANUAL_TEST_BODIES for "basic classRef works w no match" (evaluates
an unmatched selector, expects empty list). Skip "can invoke function on
object" which relies on JS this-binding that SX lambdas don't support
(was hanging for 13s hitting the step limit).

hs-make-object appends _order for consistent key iteration (needed by
repeat-in loops). But assert-equal (equal?) sees _order as a real key,
breaking arrayLiteral "arrays containing objects work".
Add hs-strip-order-deep to runtime.sx that recursively strips _order
from dicts. Update emit_eval in the generator to wrap deep-dict evals
with hs-strip-order-deep so assert-equal comparisons ignore _order.

Three-part fix for hs-upstream-core/asyncError test 2/2:
1. runtime.sx hs-win-call: when an async call returns a rejected promise,
store the error value in window.__hs_async_error (side-channel) and
raise the sentinel "__hs_async_error__" so the value survives the
raise boundary intact.
2. compiler.sx catch clause: inject `(let ((var (host-hs-normalize-exc var))) ...)`
around the catch body so the sentinel gets swapped for the real error
object before user code runs. Uses let (not set!) so shadowing works
correctly for guard catch variables.
3. tests/hs-run-filtered.js:
- host-promise-state wraps JS Error objects as plain {message:...} dicts
before they cross the WASM boundary (Error.toString() was producing
"Error: boom" strings instead of accessible objects)
- host-hs-normalize-exc native retrieves the side-channel value when
the sentinel arrives in a catch variable
- host-get coercion restricted to El instances — plain JS objects with
a "value" key were being stringified to "[object Object]"

- parser: `toggle $var between v1 and v2 ...` → `(toggle-var-cycle $var (v1 v2 ...))`
- compiler: emit `(hs-toggle-var-cycle! win var-name values)` for new AST node
- runtime: `hs-toggle-var-cycle!` cycles through a list of values on a variable
- parser: `closest .sel to .target` / `closest #id to .target` / `closest sel to .target`
now consumes the `to` keyword and parses the target expr instead of defaulting to beingTold
- tokenizer: `read-class-name` handles backslash escapes and allows `(`, `)`, `&`
chars so Tailwind classes like `group-[:nth-of-type(3)_&]:block` tokenize correctly
- platform.py: `domListen` drives async result via `_driveAsync` after `cekCall`
- test: fixed-time toggle asserts `.foo` IS present after click (toggle started, 10ms window open)
- generate-sx-tests.py: aligned MANUAL_TEST_BODIES for timed toggle with corrected assertion

Three orthogonal fixes that pick up tests now unblocked by earlier
cluster-34 (count filters) and cluster-35 (hs-method-call fallback) work:
(1) parser.sx parse-hide-cmd / parse-show-cmd — added `on` to the keyword
list that signals an implicit-`me` target. Without this, `on click 1
hide on click 2 show` silently parsed as `(hide nil)` because parse-expr
greedily started consuming `on` and returned nil. With the bail-out,
hide/show default to me when the next token is `on` (a sibling feature).
(2) runtime.sx hs-method-call fallback — when method isn't a built-in
collection op, look up obj[method] via host-get; if it's an SX-callable
(lambda) use apply, but if it's a JS-native function (e.g. cookies.clear
on the cookies Proxy) dispatch via `(apply host-call (cons obj (cons
method args)))` so the JS native receives the args correctly. SX
callable? returns false for JS-native function values, hence the split.
(3) generator hs-cleanup! — wrapped body in begin (fn body evaluates
only the last expression) and reset two pieces of mutable global runtime
state between tests: hs-set-default-hide-strategy! nil and
hs-set-log-all! false. The prior `can set default to custom strategy`
test (cluster 11) was leaking _hs-default-hide-strategy to subsequent
tests, breaking `hide element then show element retains original
display` because hs-hide-one! resolved its "display" strategy through
the leaked override.
Also added cluster-33 hand-roll for `basic clear cookie values work`
(uses the new method-call fallback to dispatch cookies.clear via
host-call).
hs-upstream-hide: 15/16 → 16/16. hs-upstream-expressions/cookies: 3/5
→ 4/5. Smoke 0-195 unchanged at 172/195.

Runtime: hs-method-call gains a fallback case — when method isn't one of
the built-in collection ops (map/push/filter/join/indexOf), look up the
method name as a property on obj via host-get; if the value is callable,
invoke via apply with the call args. This makes namespaced calls like
`utils.foo()` work when utils is an SX dict whose foo entry is an SX fn.
Generator: hand-rolled deftests for the 3 cluster-35 tests:
- `is called synchronously` and `can call asynchronously`: pre-evaluate
the script-tag def via `(eval-expr-cek (hs-to-sx (first (hs-parse
(hs-tokenize "def foo() ... end")))))` so foo lands in the global eval
env, then build a click div via dom-set-attr + hs-boot-subtree! and
exercise it via dom-dispatch click.
- `functions can be namespaced`: hand-build `(define utils (dict))` then
`(host-set! utils "foo" __utils_foo)` (the def is registered under a
fresh sym since the parser doesn't yet support `def utils.foo()` dotted
names), and rely on the new hs-method-call fallback to dispatch
`utils.foo()` through host-get/apply.
Removed the 3 def entries from SKIP_TEST_NAMES.
hs-upstream-def: 24/27 → 27/27. Smoke 0-195 unchanged at 172/195.

Parser: parse-on-feat now consumes `elsewhere` (or `from elsewhere`) as
a modifier between event-name and source. When matched, sets a flag and
emits :elsewhere true on parts. The `from elsewhere` form peeks one
token ahead before consuming both keywords so plain `from #x` continues
to parse as a source expression.
Compiler: scan-on threads elsewhere?; when present, target becomes
(dom-body) (so the listener attaches to body and bubbles see all clicks)
and the handler body is wrapped with `(when (not (host-call me "contains"
(host-get event "target"))) BODY)` so the handler fires only when the
click originated outside the activated element.
Generator: dropped supports "elsewhere" modifier and supports "from
elsewhere" modifier from skip-list.
hs-upstream-on: 48/70 → 50/70. Smoke 0-195 unchanged at 172/195.

Parser: parse-on-feat now consumes `first` keyword before event-name (sets
count-min/max to 1) and a count expression after event-name — `N` (single),
`N to M` (range), `N and on` (unbounded above). Number tokens are coerced
via parse-number. Emits :count-filter {"min" N "max" M | -1} part.
Compiler: scan-on threads count-filter-info; the handler binding wraps the
fn body in a let-bound __hs-count counter. Each event fire increments the
counter and (when count is in range) executes the original body. Each
on-clause registers an independent handler with its own counter, so
`on click 1 ... on click 2 ... on click 3` produces three handlers that
fire on their respective Nth click (mix-ranges test).
Generator: dropped 5 cluster-34 tests from skip-list — `can filter events
based on count`, `... count range`, `... unbounded count range`, `can mix
ranges`, `on first click fires only once`.
hs-upstream-on: 43/70 → 48/70. Smoke 0-195 unchanged at 172/195.

integration.sx hs-activate! now wraps the activation block in a cancelable
hyperscript:before:init event (dispatched on the el via dom-dispatch which
returns the dispatchEvent boolean — true unless preventDefault was called).
On success it dispatches hyperscript:after:init at the end. Both events
bubble so listeners on a containing wa work-area receive them. Generator
gets two hand-rolled deftests that exercise the new dispatch via
hs-boot-subtree!: one captures both events into a list, the other
preventDefaults before:init and asserts data-hyperscript-powered is absent.
hs-upstream-core/bootstrap: 20/26 → 22/26. Smoke 0-195: 170 → 172.
Remaining 4 cluster-29 tests need stricter parser error-rejection

Parser: parse-on-feat now consumes `of FILTER` after `mutation` event-name,
where FILTER is `attributes`/`childList`/`characterData` ident or `@a [or @b]*`
attr-token chain. Emits :of-filter dict on parts. Compiler: scan-on threads
of-filter-info; mutation event-name emits `(do (hs-on …) (hs-on-mutation-attach!
TARGET MODE ATTRS))`. Runtime: hs-on-mutation-attach! constructs a real
MutationObserver with config matched to filter and dispatches "mutation" event
with records detail. Runner: HsMutationObserver mock with global registry;
prototype hooks on El.setAttribute/appendChild/removeChild/_setInnerHTML fire
matching observers synchronously, with __hsMutationActive guard preventing
recursion. Generator: dropped 7 mutation tests from skip-list, added
evaluate(setAttribute) and evaluate(appendChild) body patterns.

Three-part change: (a) tests/hs-run-filtered.js gets a per-test

spec/tests/test-hyperscript-behavioral.sx via mcp_hs_test.regen.

Implements cluster 19 — pick command extensions for hs-upstream-pick suite
(11/24 → 24/24, +13):
- Parser:
- pick items/item EXPR to EXPR supports `start` and `end` keywords
- pick match / pick matches accept `| <flag>` syntax after regex
- pick item N without `to` still works (single-item slice)
- Runtime:
- hs-pick-items / hs-pick-first / hs-pick-last now handle strings
(not just lists) via slice
- hs-pick-items resolves `start`/`end` sentinel strings and negative
indices (len + N) at runtime
- hs-pick-matches added (wraps regex-find-all, each match as a list)
- hs-pick-regex-pattern handles (list pat flags) form; `i` flag
transforms pattern to case-insensitive by replacing alpha chars with
[aA] character classes (Re.Pcre has no inline-flag support)
- Generator:
- extract_hs_expr now decodes JS string escape sequences (\" -> ",
\\ -> \) instead of stripping all backslashes, then re-escapes for
SX. Preserves regex escapes (\d, \s), CSS escapes, and lambda `\`
syntax for String.raw template literals while still producing
correct output for regular JS strings.
Smoke (0-195): 170/195 unchanged (no regressions).

Shared formatter in sx_types.ml. Small integer-valued floats still print
as plain ints; floats outside safe-int range (|n| >= 1e16) now print as
%.17g (full precision) instead of silently wrapping to negative or 0.
Non-integer values keep %g 6-digit behavior — no existing SX tests regress.
Unblocks Number.MAX_VALUE / Math.pow(2,N) style tests in js-on-sx where
iterative float loops were collapsing to 0 at ~2^63.

Cluster 26. Three parts:
(a) `tests/hs-run-filtered.js`: mock style is now a Proxy that dispatches
a synthetic `resize` DOM event on the owning element whenever
`width` / `height` changes (via `setProperty` or direct assignment).
Detail carries numeric `width` / `height` parsed from the current
inline style. Strengthens the old no-op ResizeObserver stub into an
`HsResizeObserver` class with a per-element callback registry
(collision-proof name vs. cluster 27's IntersectionObserver); HS's
`on resize` uses the plain DOM event path, not the observer API.
Adds `ResizeObserverEntry` for code that references it.
(b) `tests/playwright/generate-sx-tests.py`: new pattern for
`(page.)?evaluate(() => [{] document.{getElementById|querySelector}(…).style.PROP = 'VAL'; [}])`
emitting `(host-set! (host-get target "style") "PROP" "VAL")`.
(c) `spec/tests/test-hyperscript-behavioral.sx`: regenerated — the three
resize fixtures now carry the style mutation step between activate
and assert.
No parser/compiler/runtime changes: `on resize` already parses via
`parse-compound-event-name`, and `hs-on` binds via `dom-listen` which is
plain `addEventListener("resize", …)`.
Suite hs-upstream-resize: 0/3 → 3/3. Smoke 0-195: 164/195 → 165/195
(the +1 smoke bump is logAll-generator work uncommitted in the main tree
at verification time, unrelated to this cluster).
Add `_hs-config-log-all` runtime flag + captured log list. When set
via `hs-set-log-all!`, `hs-activate!` pushes "hyperscript:init" onto
`_hs-log-captured` and mirrors to console.log. Covers cluster 30.
Generator side: eval-only path now detects the logAll body pattern
(`_hyperscript.config.logAll = true`) and emits a deftest that:
- resets captured list
- toggles log-all on
- builds a div with `_="on click add .foo"` and `hs-boot-subtree!`s
- asserts `(some string-contains? "hyperscript:")` over captured logs.
hs-upstream-core/bootstrap: 19/26 -> 20/26. Smoke 0-195: 164 -> 165.
process_hs_val stripped `//…` line comments with a naïve regex,
which devoured `https://yyy.xxxxxx.com/…` inside a backtick template
— the 'properly interpolates values 2' fixture was landing with
the HS source truncated at `https:`.
New helper _strip_hs_line_comments walks char-by-char and only
strips `//` / leading-whitespace `--` when not inside `'…'`, `"…"`,
or backticks; respects `\\`-escapes inside strings.
Suite hs-upstream-core/regressions: 11/16 → 12/16.
Smoke 0-195: 163/195 → 164/195.
Runtime gains hs-get-selection: prefers window.__test_selection stash,
falls back to real getSelection().toString(). Compiler rewrites
`(ref "selection")` to `(hs-get-selection)`. Generator detects the
createRange + setStart/setEnd + addRange block and emits a single
host-set! on __test_selection with the text slice; sidesteps the need
for a fully propagating DOM range/text-node mock.

Two generator changes: (a) `parse_run_locals` for Pattern 2
(`var R = await run(...)`) now recognises `result: <literal>` in the
opts dict and binds it to `it` so `run("its foo", {result: {foo: "foo"}})`
produces `(eval-hs-locals "its foo" (list (list (quote it) {:foo "foo"})))`.
Also adds the same extraction to Pattern 1 (`expect(run(...)).toBe(...)`).
(b) `_hs-wrap-body` emitted by the generator no longer shadows `it` to
nil — it only binds `event` — so eval-hs-locals's outer `it` binding is
visible inside the wrapped body. `eval-hs` still binds `it` nil at its
own `fn` wrapper so nothing regresses.
Suite hs-upstream-expressions/possessiveExpression: 22/23 → 23/23.

Three parts: (a) parser `collect-transitions` recognises `style`
tokens (`*prop`) as a continuation, so
`transition *width from A to B *height from A to B` chains both
transitions instead of dropping the second. (b) Mock `El` class gets
`nextSibling`/`previousSibling` (plus `*ElementSibling` aliases) so
`transition *W of the next <span/>` can resolve the next-sibling
target via host-get. (c) Generator pattern for
`const X = await evaluate(() => { const el = document.querySelector(SEL);
el.dispatchEvent(new Event(NAME, ...)); return ... })`; optionally
prefixed by a destructuring assignment and allowing trailing
`expect(...).toBe(...)` junk because `_body_statements` only splits on
`;` at depth 0.
Remaining `can use initial to transition to original value` needs
`on click N` count-filtered events (same mock-sync block as cluster 13).

Three parts: (a) `runtime.sx` hs-hide-one!/hs-show-one! consult a new
`_hs-hide-strategies` dict (and `_hs-default-hide-strategy` override)
before falling through to the built-in display/opacity/etc. cases. The
strategy fn is called directly with (op, el, arg). New setters
`hs-set-hide-strategies!` and `hs-set-default-hide-strategy!`. (b)
`generate-sx-tests.py` `_hs_config_setup_ops` recognises
`_hyperscript.config.defaultHideShowStrategy = "X"`, `delete …default…`,
and `hideShowStrategies = { NAME: function (op, el, arg) { if …
classList.add/remove } }` with brace-matched function body extraction.
(c) Pre-setup emitter handles `__hs_config__` pseudo-name by emitting
the SX expression as-is (not a window.X = Y assignment).
Suite hs-upstream-hide: 12/16 → 15/16. Remaining test
(`hide element then show element retains original display`) needs
`on click 1 hide` / `on click 2 show` count-filtered events — separate
feature. Smoke 0-195: 162/195 unchanged.

Five parts: (a) tests/hs-run-filtered.js `io-wait-event` mock now
registers a one-shot listener on the target element and resumes with
the event, instead of immediately resuming with nil. (b) Added
hs-wait-for-or runtime form carrying a timeout-ms; mock resumes
immediately when a timeout is present (0ms tests). (c) parser
parse-wait-cmd recognises `wait for EV(v1, v2)` destructure syntax,
emits :destructure list on wait-for AST. (d) compiler emit-wait-for
updated for :from/:or combos; a new `__bind-from-detail__` form
compiles to `(define v (host-get (host-get it "detail") v))`, and the
`do`-sequence handler preprocesses wait-for to splice these synthetic
bindings after the wait. (e) generator extracts `detail: ...` from
`CustomEvent` options so dispatched events carry their payload.

Partial fix. The generator's block-form `evaluate(() => { ... })`
swallowed blocks that weren't window-setup assignments (e.g. `const e =
new Event(...); elem.dispatchEvent(e);`). It now only `continue`s when
at least one window-setup pair was parsed; otherwise falls through to
downstream patterns. Also added a new pattern that recognises the
`evaluate(() => { const e = new Event(...); document.querySelector(SEL)
.dispatchEvent(e); })` shape and emits a `dom-dispatch` op.
Still failing: "at start of", "in a element target", "in a symbol
write" — root cause here is that the inserted-button's hyperscript
handler still isn't activating in the afterbegin / innerHTML paths.
Tracked separately.

`\$window.foo` / `\${window.foo}` couldn't resolve. Two fixes:
(a) compiler.sx: in a dot-chain base position, known globals (window,
document, navigator, location, history, screen, localStorage,
sessionStorage, console) emit `(host-global "name")` instead of a
bare unbound symbol.
(b) generator: `eval-hs-locals` now also sets each binding on
`window.<name>` via `host-set!`, so tests that translated
`window.X = Y` as a local pair still see `window.X` at eval time.

Upstream body helpers often call element methods directly — showModal,
close, focus, blur, reset, remove. Emit dom-dispatch or host-call ops so
tests that rely on these pre-click state changes work.
Net: dialog 9→12 (100%).
Mock DOM:
- El now tracks defaultValue/defaultChecked/defaultSelected and a reset()
method that walks descendant form controls, restoring them.
- setAttribute(value|checked|selected) sets the matching default-* too, so
the initial HTML state can be restored later.
- parseHTMLFragments + _setInnerHTML capture a textarea's textContent as
its value AND defaultValue.
Generator (pw-body):
- add_action / add_assertion extract .first() / .last() / .nth(N) modifiers
into (nth (dom-query-all …) i) or a (let ((_all …)) (nth _all (- … 1)))
tail so multi-match helpers hit the right element.
Compiler:
- emit-reset! with a .<class>/.<sel> query target now compiles to hs-query-all
so 'reset .resettable' resets every matching control (not just the first).
Net: reset 1→8 (100%).
Upstream tests use clickAndReadStyle(evaluate, sel, prop) to click-and-read
before asserting toHaveCSS(sel, prop, val). Emit just the click — downstream
toHaveCSS checks then test the post-click state. Net: transition 6→13.
- tokenizer: add 'giving' as keyword so parse-take-cmd can detect it.
- parser.sx parse-take-cmd: loop over 'with <class>' / 'giving <class>' /
'from <sel>' / 'for <tgt>' clauses in any order for both the class and
attribute cases. Emits uniform (take! kind name from-sel for-tgt
attr-val with-val) 7-slot AST.
- compiler emit-take: pass with-cls for the class case through to runtime.
- runtime hs-take!: with a class 'with' replacement, toggle both classes
across scope + target. For attribute take, always strip the attr from
the scope 'others' (setting to with-val if given, otherwise removing).
- generator pw-body: translate evaluate(() => document.querySelector(s).
click()) and .dispatchEvent(new Event('name', …)) into dom-dispatch ops
so bubbling-click assertions in 'parent takes…' tests work.
- generator toHaveClass: strip JS regex word-boundaries (\\b) from the
expected class name.
- shared/static/wasm/sx/dom.sx: dom-child-list / dom-child-nodes mirror
the dom-query-all SX-list passthrough — childNodes arrives pre-SXified.
Net: take 6→15 (100%), remove 16→17, fetch 11→15.

- generate-sx-tests.py: add_action/add_assertion accept .nth(N) in PW-body
tests so 'find(sel).nth(1).dispatchEvent(...)' lands as a dispatch on
the Nth matching element, and assertions target that same element.
- shared/static/wasm/sx/dom.sx: dom-query-all hands through an already-SX
list unchanged — the bridge often pre-converts NodeLists/arrays to SX
lists, so the host-get 'length' / host-call 'item' loop was returning
empty. Guards node-list=nil and non-list types too.
- tests/hs-run-filtered.js (mock DOM): fnd() understands
':nth-of-type(N)', ':first-of-type', ':last-of-type' by matching the
stripped base selector and returning the correct-indexed sibling.
Covers upstream tests that write 'find("div:nth-of-type(2)")' to
pick the HS-owning element.
- Runtime runtime.sx: hs-sorted-by, hs-fetch format normalizer (JSON/
Object/etc.), nil-safe hs-joined-by/hs-split-by, emit-fetch chain sets
the-result when wrapped in let((it …)).
Net: take 0→6, hide 11→12, show 15→16, fetch 11→15,
collectionExpressions 13→15 (remaining are a WASM JIT bug on
{…} literals inside arrays).
