Parser: parse-js-block extracts raw JS source by character positions.
Compiler: js-block AST → hs-js-exec call, stores result in it.
Runtime: hs-js-exec creates JS Function, handles promise rejection.
Test runner: host-new-function/host-promise-state natives + promise monkey-patch.

hs-make-object no longer appends _order to every HS object literal.
Generator emit_eval now uses assert-equal (equal?) for dict-containing
expected values instead of assert= (= reference equality).
Together these fix arrayLiteral "arrays containing objects work".

empty .class compiled (empty-target (query ".class")) to
(hs-empty-target! (hs-query-first ".class")) via hs-to-sx — only
emptying the first match. Fix: detect (query ...) target in the
empty-target compiler case and emit (for-each (fn (_el)
(hs-empty-target! _el)) (hs-query-all sel)) instead, mirroring the
add-class pattern. Suite hs-upstream-empty: 12/13 → 13/13.
Smoke 0-195: 175/195 unchanged.

${}{"val"} pattern in add {prop: ${}{"val"}} uses two consecutive brace
groups: empty ${} followed by {"val"} for the actual expression. The prior
fix called parse-expr when already at the brace-close of the empty group,
returning nil. New fix: detect empty ${} (brace-open then brace-close),
skip the close, then read the actual value from the following {…} block.
Also handles non-empty ${expr} directly as before.
Suite hs-upstream-add: 17/19 → 18/19. Smoke 0-195: 174/195 → 175/195.

call X then put it into Y was emitting (hs-win-call ...) without
wrapping in emit-set, so it remained nil. Wrap call result in
emit-set(the-result) so it/the-result are updated. Fixes +1 test.

Prevents click events from bubbling into ancestor elements that also
have hs handlers (e.g. parent re-inserting HTML after child click).
Fixes put-reprocessing tests 1147/1149/1150 (+3 tests).

tell now rebinds beingTold/you/yourself without overwriting me.
Parser implicit targets use beingTold; handler wrapper seeds beingTold=me.
Fixes: attributes refer to the thing being told, does not overwrite me,
your symbol represents the thing being told.

- _NO_STEP_LIMIT set exempts hypertrace tests from the 200k step cap
- globalThis.__hs_deadline exposed so cek_step_loop wall-clock check
(every 10k steps) can terminate runaway async loops without needing
to go through host-call or _driveAsync
- meta + _hs-on-caller added to hs-runtime.sx (both lib and bundled):
on-event handlers now set meta.caller to an object with
meta.feature.type = "onFeature" before calling the handler
Tests 196 (async hypertrace), 198 (meta.caller), 199, 200 now pass.

Add hs-tokenize-template: scans " as single STRING token, ${ ... }
as dollar+brace+inner-tokens (inner tokenized with hs-tokenize), and
} as brace-close. Update hs-tokens-of to call hs-tokenize-template
when :template keyword arg is passed. Unlocks tests 1 and 15.

Add \r \b \f \v and \xNN escape handling to read-string. Use
char-from-code for non-SX-literal chars. Throw "Unterminated string"
on EOF inside a string literal. Throw "Invalid hexadecimal escape: \x"
on bad \xNN. Add hs-hex-digit? and hs-hex-val helpers. Unlocks
tests 2, 6, 13, 14 once generator lands.

Add hs-eof-sentinel, hs-op-type, hs-raw->api-token, hs-tokens-of,
hs-stream-token, hs-stream-consume, hs-stream-has-more, and the
three token accessors (hs-token-type, hs-token-value, hs-token-op?).
No test delta yet — API-only, generator comes in step 6.

Threads declaration kind ("var"/"let"/"const") through js-transpile-var →
js-vardecl-forms so the transpiler knows which kind is being declared.
Infrastructure for full TDZ enforcement: js-tdz-check can wrap let/const
reads to raise TypeError before initialization.
Updates plans/js-on-sx.md: ticks [x] for TDZ, marks regex blocker RESOLVED,
adds progress log entry for 2026-04-25.

`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.

- Remove guard wrapper from hs-win-call emit (direct call is sufficient now)
- def command also registers fn on window[name] so hs-win-call finds it
- Generator: fix \"-escaped quotes in hs-compile string literal (was splitting "here" into three SX nodes)
- Hand-rolled deftest for 'can refer to function in init blocks' now passes

- pl-eval-arith: add floor, ceiling, truncate, round, sqrt, sign, pow, integer,
float, float_integer_part, float_fractional_part, **, ^ operators
- pl-collect-vars: helper that extracts unbound variables from a term (left-to-right,
deduplicated by var id)
- term_variables/2: dispatches via pl-collect-vars, unifies second arg with var list
- pl-predsort-insert!: inserts one element into a sorted list using a 3-arg comparator
predicate; deduplicates elements where comparator returns '='
- pl-predsort-build!: builds sorted list via fold over pl-predsort-insert!
- predsort/3: full ISO predsort — sorts and deduplicates a list using a caller-supplied
predicate
- lib/prolog/tests/advanced.sx: 21 tests (12 arith, 5 term_variables, 4 predsort)
- conformance.sh: add advanced suite
- scoreboard: 517/517 (was 496/496)

Adds two new builtins to lib/prolog/runtime.sx:
- sub_atom/5: non-deterministic substring enumeration. Iterates all
(start, length) pairs over the atom string, tries to unify Before,
Length, After, SubAtom for each candidate. Uses CPS loop helpers
pl-substring, pl-sub-atom-try-one!, pl-sub-atom-loop!. Fixed trail
undo semantics: only undo on backtrack (k returns false), not on success.
- aggregate_all/3: collects all solutions via pl-collect-solutions then
reduces. Templates: count, bag(T), sum(E), max(E), min(E), set(T).
max/min fail on empty; count/bag/sum/set always succeed.
New test suite lib/prolog/tests/string_agg.sx: 25 tests, all passing.
Total conformance: 496/496.

- parser.sx: add (":-" 1200 "xfx") to pl-op-table so (head :- body) parses
inside paren expressions (parens reset prec to 1200, allowing xfx match)
- parser.sx: extend pl-token-op to accept "op" token type, not just "atom",
since the tokenizer emits :- as {:type "op" :value ":-"}
- tests/assert_rules.sx: 15 new tests covering assertz/asserta with rule
terms, conjunction in rule body, recursive rules, and ordering
- conformance.sh: wire in assert_rules suite
- 456 → 471 tests, all passing
