`1 in [1, 2, 3]` must return (list 1) not true. Root cause: in? compiled
to hs-contains? which returns boolean for scalar items. Fix: new hs-in?
returns filtered list; new in-bool? operator for is/am-in comparison
contexts so those still return boolean. Parser generates in-bool? for
`X is in Y` / `X am in Y`; plain `in` keeps in? → list return.

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 `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.

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.

Wire up the `ask` and `answer` commands end-to-end:
- tokenizer.sx: register `ask` and `answer` as hs-keywords.
- parser.sx: cmd-kw? gains both; parse-cmd dispatches to new
parse-ask-cmd (emits `(ask MSG)`) and parse-answer-cmd, which
reads `answer MSG [with YES or NO]`. The with/or pair reads
yes/no via parse-atom — parse-expr would collapse
`"Yes" or "No"` into `(or "Yes" "No")` before match-kw "or"
could fire. The no-`with` form emits `(answer-alert MSG)`.
- compiler.sx: three new cond branches (ask, answer, answer-alert)
compile to a let that binds __hs-a, sets `the-result` and `it`,
and returns the value — so `then put it into ...` works.
- runtime.sx: hs-ask / hs-answer / hs-answer-alert call
window.prompt / confirm / alert via host-call + host-global.
- tests/hs-run-filtered.js: test-name-keyed globalThis.{alert,
confirm,prompt}; __currentHsTestName is updated before each
test. Host-set! for innerHTML/textContent now coerces JS
null → "null" (browser behaviour) so `prompt → null` →
`put it into #out` renders literal text "null", which the
fourth test depends on.
Suite hs-upstream-askAnswer: 1/5 -> 5/5.
Smoke 0-195: 166/195 -> 170/195.
Re-applied from worktree-agent-a7c6dca2be5bbada0 (commit c4241d57)
onto HEAD that already has clusters 30, 26, 27 runtime changes —
straight cherry-pick conflicted on the cluster-30 log-all block
and cluster-27 intersection helper, so the logical diff was
replayed surgically.
Parser (parse-atom object-literal):
- obj-collect now `append`s pairs in source order instead of
`cons`'ing, so `{foo:1, bar:2, baz:3}` reaches hs-make-object
as `((foo 1) (bar 2) (baz 3))`.
Compiler (emit-for, array-index emission):
- emit-for detects `for x in COLL where COND` (parser wraps COLL
as `(coll-where INNER COND)`) and rewrites the filter lambda
to bind the for-loop variable name rather than the default
`it`, so `where x.val > 10` sees the right binding. Also
unwraps `coll-where` so filter targets the real inner coll.
- emit-for now wraps a symbol collection with `cek-try` (not the
broken `hs-safe-call`, which has an uninitialised CEK call-ref
in the WASM build) so `for prop in x` after `set x to {…}`
iterates x's keys instead of nil.
- array-index emits `(hs-index obj key)` instead of
`(nth obj key)`, which only worked on lists.
Runtime:
- New polymorphic `hs-index` dispatches to get / nth / host-get
based on target type (dict / list / string / otherwise).
- `hs-put-at!` default branch now detects DOM elements via
`hs-element?` and delegates to `hs-put!`, so `put X at end of
elt` on a DOM node appends innerHTML instead of crashing.
- `hs-make-object` tracks insertion order in a hidden `_order`
list; `hs-for-each` and `hs-coerce` (Keys / Entries / Map
branches) prefer `_order` when present, filtering the marker
out of output.
Suite hs-upstream-repeat: 25/30 → 28/30 (+3).
Smoke 0-195 unchanged at 165/195.
Applied from worktree-agent-ad6e17cbc4ea0c94b (commit 0a0fe314)
with manual re-apply onto post-cluster-26 HEAD:
- Parser: parse-on-feat collects `having margin X threshold Y`
clauses between `from X` and the body; packs them into a
`:having {"margin" M "threshold" T}` dict on the parts list.
- Compiler: scan-on threads a new `having-info` parameter through
all recursions; when event-name is "intersection", wraps the
hs-on call with `(do on-call (hs-on-intersection-attach! target
margin threshold))`.
- Runtime: hs-on-intersection-attach! constructs an
IntersectionObserver with {rootMargin, threshold} options and a
callback that dispatches an "intersection" DOM event carrying
{intersecting, entry} detail.
- Runner: HsIntersectionObserver mock fires the callback
synchronously on observe() with isIntersecting=true so handlers
run during activation; ignores margin/threshold (tests assert
only that the handler fires).
Suite hs-upstream-on: 33/70 -> 36/70 (on intersection: 0/3 -> 3/3).
Smoke 0-195 unchanged at 165/195.
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.
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.

`hs-on` now wraps each event handler in a `guard` that catches thrown
exceptions and re-dispatches them as an `exception` DOM event on the
same target with `{error: e}` as detail. The `on exception(error)`
handler, registered the same way, receives the event and destructures
`error` from the detail. Wrapping skips `exception`/`error` event
handlers to avoid infinite loops — those bubble out as before.
Suite hs-upstream-throw: 5/7 → 7/7. Smoke 0-195: 162/195 unchanged.

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.

Three-part fix: (a) emit-send now builds detail=(dict "sender" me) on
(send NAME target) and bare (send NAME) instead of nil, so the receiving
handler has access to the sending element. (b) parser parse-atom now
recognises the `sender` keyword (previously swallowed as noise) and
emits it as (sender). (c) compiler translates bare `sender` symbol and
(sender) list-head to (hs-sender event) — a new runtime helper that
reads (get (host-get event "detail") "sender").

Dict-set! keys iterate in scrambled order, so Values|FormEncoded and
Values|JSONString produced output in the wrong order. Fix: hs-values-absorb
now tracks insertion order in a hidden `_order` list on the dict itself.
hs-coerce FormEncoded/JSONString paths read `_order` when present and
iterate in that order (filtering the marker key out).

Adds hs-host-to-sx to convert raw host-handle JS objects/arrays returned by
json-parse or io-fetch into proper SX dicts/lists. hs-fetch now calls it on
the result when format is "json". Detects host handles via absence of the
internal `_type` marker, then walks Object.keys / Array items recursively.

(strings flow through unchanged).
- New hs-pick-match / hs-pick-matches wrappers around regex-match /
regex-find-all, also nil-safe; compiler routes pick-match / pick-matches
through them. Unblocks 'pick first from null returns null' and
'pick match from null returns null' which previously looped past
step_limit.
- 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

- 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

lists, so the host-get 'length' / host-call 'item' loop was returning
empty. Guards node-list=nil and non-list types too.

Runtime (lib/hyperscript/ + shared/static/wasm/sx/hs-*.sx):
- make: parser accepts `<tag.class#id/>` selectors and `from <expr>,…`; compiler
emits via scoped-set so `called <name>` persists; `called $X` lands on
window; runtime dispatches element vs host-new constructor by type.
- Values: `x as Values` walks form inputs/selects/textareas, producing
{name: value | [value,…]}; duplicates promote to array; multi-select and
checkbox/radio handled.
- toggle *display/*visibility/*opacity: paired with sensible inline defaults
in the mock DOM so toggle flips block/visible/1 ↔ none/hidden/0.
- add/remove/put at array: emit-set paths route list mutations back through
the scoped binding; add hs-put-at! / hs-splice-at! / hs-dict-without.
- remove OBJ.KEY / KEY of OBJ: rebuild dict via hs-dict-without and reassign,
since SX dicts are copy-on-read across the bridge.
- dom-set-data: use (host-new "Object") rather than (dict) so element-local
storage actually persists between reads.
- fetch: hs-fetch normalizes JSON/Object/Text/Response format aliases;
compiler sets `the-result` when wrapping a fetch in the `let ((it …))`
chain, and __get-cmd shares one evaluation via __hs-g.
Mock DOM (tests/hs-run-filtered.js):
- parseHTMLFragments accepts void elements (<input>, <br>, …);
- setAttribute tracks name/type/checked/selected/multiple;
- select.options populated on appendChild;
- insertAdjacentHTML parses fragments and inserts real El children into the
parent so HS-activated handlers attach.
Generator (tests/playwright/generate-sx-tests.py):
- process_hs_val strips `//` / `--` line comments before newline→then
collapse, and strips spurious `then` before else/end/catch/finally.
- parse_dev_body interleaves window-setup ops and DOM resets between
actions/assertions; pre-html setups still emit up front.
- generate_test_pw compiles any `<script type=text/hyperscript>` (flattened
across JS string-concat) under guard, exposing def blocks.
- Ordered ops for `run()`-style tests check window.obj.prop via new
_js_window_expr_to_sx; add DOM-constructing evaluate + _hyperscript
pattern for `as Values` tests (result.key[i].toBe(…)).
- js_val_to_sx handles backticks and escapes embedded quotes.

Last commit's `hs-type-check` rewrite collapsed predicate and assertion
into one runtime fn that always raised on mismatch. That fixed `: Type`
but broke `is a Type` / `is not a Type` (which need a bool):
null is a String expected true, got nil (raised)
null is not a String expected false, got true (default boolean)
Restored the split. Parser now emits `(type-assert ...)` for `:` and
keeps `(type-check ...)` for `is a` / `is not a`. Runtime adds:
- `hs-type-check` — predicate, never raises (nil passes)
- `hs-type-check-strict` — predicate, false on nil
- `hs-type-assert` — value or raises
- `hs-type-assert-strict` — value or raises (also raises on nil)
Compiler maps `type-assert` / `type-assert-strict` to the new runtime fns.
comparisonOperator 74/83 → 79/83 (+5: `is a/an`, `is not a/an` four tests

`'foo' : String` and `'foo' : String!` were returning `true` because
`hs-type-check` was a predicate. Per upstream hyperscript semantics,
`value : Type` is a type-asserted pass-through:
- nil passes the basic check (use `Type!` for non-null)
- mismatched type → raise "Typecheck failed!"
- match → return the original value
`hs-type-check-strict` now also raises on nil rather than returning
false, so the `String!` form actually rejects null.
hs-upstream-expressions/typecheck: 0/5 → 2/5.
asExpression unchanged (uses different `as Type` runtime path).

Generator changes (tests/playwright/generate-sx-tests.py):
- toHaveCSS regex: balance parens so `'rgb(255, 0, 0)'` is captured intact
(was truncating at first `)`)
- Map browser-computed colors `rgb(R,G,B)` back to CSS keywords
(red/green/blue/black/white) — our DOM mock returns the inline value
- js_val_to_sx now handles object literals `{a: 1, b: {c: 2}}` → `{:a 1 :b {:c 2}}`
- Pattern 2 (`var x = await run(...)`) now captures locals via balanced-brace
scan and emits `eval-hs-locals` instead of `eval-hs`
- Pattern 1 with locals: emit `eval-hs-locals` (was wrapping in `let`, which
doesn't reach the inner HS env)
- Stop collapsing `\"` → `"` in raw HTML (line 218): the backslash escapes
are legitimate in single-quoted `_='...'` HS attribute values containing
nested HS scripts
Test-framework changes (regenerated into spec/tests/test-hyperscript-behavioral.sx):
- `_hs-wrap-body`: returns expression value if non-nil, else `it`. Lets bare
expressions (`foo.foo`) and `it`-mutating scripts (`pick first 3 of arr;
set $test to it`) both round-trip through the same wrapper
- `eval-hs-locals` now injects locals via `(let ((name (quote val)) ...) sx)`
rather than `apply handler (cons nil vals)` — works around a JIT loop on
some compiled forms (e.g. `bar.doh of foo` with undefined `bar`)
Also synced lib/hyperscript/*.sx → shared/static/wasm/sx/hs-*.sx (the WASM
test runner reads from the wasm/sx/ copies).

- `remove VALUE from :var` → (remove-value) for array removal
- `toggle .foo for 10ms` → (toggle-class-for) with duration
- `append VALUE` without `to` → implicit target (it)
- `set {obj} on target` → (set-on) for object property spread
- `repeat in` body: remove spurious nil (body at index 3→2)
- Keywords followed by `(` parsed as function calls (fixes `increment()`)

Compiler: do-blocks now compile to (let ((it cmd1)) (let ((it cmd2)) ...))
instead of (do cmd1 cmd2 ...). This chains the `it` variable through
command sequences, enabling `fetch X then put it into me` pattern.
Each command's result is bound to `it` for the next command.
Runtime: hs-fetch simplified to single perform (io-fetch url format)
instead of two-stage io-fetch + io-parse-text/json.
Parser: fetch URL /path handled by reading /+ident tokens.
Default fetch format changed to "text" (was "json").
Test runner: mock fetch routes with format-specific responses.
io-fetch handler returns content directly based on format param.
Fetch tests still need IO suspension to chain through let continuations.

- Parser: multi-property transition (width from 0px to 100px height from...)
with collect-transitions loop. CSS value parsing uses parse-atom + manual
number+unit concat to avoid greedy string-postfix chaining.
- Compiler: take! passes attr-val and with-val (restored from revert)
- Runtime: hs-empty-target! handles FORM by iterating child inputs,
hs-starts-with-ic/hs-ends-with-ic for case-insensitive comparison

Root cause: sx_insert_near placed break-lines-greedy, pretext-position-line,
pretext-layout-lines OUTSIDE the define-library begin block. The bytecode
compiler only compiles forms inside begin as STORE_GLOBAL — forms outside
are invisible to the browser VM.
Fix: moved all function definitions inside (begin ...) of (define-library).
Bytecode now includes all 17 functions (11K compiled, was 9K).
Browser load-sxbc: simplified VmSuspended handling — just catch and
continue, since STORE_GLOBAL ops already ran before the import OP_PERFORM.
sync_vm_to_env copies them to global_env.
Island now calls break-lines and pretext-layout-lines from bytecode-compiled
library — runs on VM, not CEK interpreter.

Streaming chunked transfer with shell-first suspense and resolve scripts.
Hyperscript parser/compiler/runtime expanded for conformance. WASM static
assets added to OCaml host. Playwright streaming and page-level test suites.

- put parser: added 'at start of' and 'at end of' positional syntax
- take parser: added 'for' as alternative to 'from' for target clause
- runtime: hs-put! handles "start" (afterbegin) and "end" (beforeend)
- eval-hs: smart wrapping for commands vs expressions

- sx_browser.ml: restore VmSuspended handler in api_call_fn with
make_js_callFn_suspension for IO suspension chains (wait, fetch)
- runtime.sx: delete host-get stub that shadowed platform native —
hs-toggle-class! now uses real FFI host-get for classList access
All three live demo examples work:
Toggle Color — classList.toggle on click
Bounce — add .animate-bounce, wait 1s suspend, remove
Count Clicks — increment @data-count, put into innerHTML
4/4 bytecode regression tests pass (was 0/4 without VmSuspended).

Three bugs fixed:
1. host-get in sx-platform.js: return true for function-valued properties
so dom-get-attr/dom-set-attr guards pass (functions can't cross WASM boundary)
2. hs-runtime.sx: renamed host-get→hs-host-get and dom-query→hs-dom-query to
stop shadowing platform natives when loaded as .sx source
3. compile-modules.js: HS dependency chain (integration→runtime→compiler→parser→tokenizer)
so lazy loading pulls in all deps. Non-library modules load as .sx source
for CEK env visibility.
Result: 8/8 elements activate, hs-on attaches listeners. Click handler needs
IO suspension support (VmSuspended in sx_browser.ml) to fire — next step.

Reset to last known-good state (908f4f80) where links, stepper, and
islands all work, then recovered all hyperscript implementation,
conformance tests, behavioral tests, Playwright specs, site sandbox,
IO-aware server loading, and upstream test suite from f271c88a.
Excludes runtime changes (VM resolve hook, VmSuspended browser handler,
sx_ref.ml guard recovery) that need careful re-integration.

- Compiler match for type-check-strict was still using old name type-check!
- Deploy updated HS source files to shared/static/wasm/sx/
- Sandbox runner validates 16/16 hard cases pass with cek-eval
(no runtime let-binding hacks needed in WASM context)

The when form's continuation for the second body expression was lost
across perform/cek_resume cycles. Wrapping (thunk) and (do-repeat)
in an explicit (do ...) gives when a single body, and do's own
continuation handles the sequencing correctly.
Sandbox confirms: 6/6 io-sleep suspensions now chain through
host-callback → _driveAsync → resume_vm (was 1/6 before fix).
Also fix sandbox async timing: _asyncPending counter tracks in-flight
IO chains so page.evaluate waits for all resumes to complete.
