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.

- Mark cluster 22 done (+1): can refer to function in init blocks
- Scoreboard: merged 1280→1302 (+22 from stale rows 22/29/32/33/34/35)
- Fix stale rows: clusters 29 partial, 32 done, 33 partial+4, 34 partial+7, 35 done

- 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

- js-big-int-str-loop: extract decimal digits from integer-valued float
- js-find-decimal-k: find min decimal places k where round(n*10^k)/10^k == n
- js-format-decimal-digits: insert decimal point into digit string at position (len-k)
- js-number-to-string: if 6-sig-fig round-trip fails AND n in [1e-6, 1e21),
use digit extraction for full precision (up to 17 sig figs)
- String(1.0000001)="1.0000001", String(1/3)="0.3333333333333333"
- String test262 subset: 58→62/100

- js-to-string: return __js_string_value__ for String wrapper dicts
- js-loose-eq: coerce String wrapper objects to primitive before compare
- String.__callable__: set __js_string_value__ + length on 'this' when called as constructor
- js-expand-sci-notation: new helper converts mantissa+exp to decimal or integer form
- js-number-to-string: expand 1e-06→0.000001, 1e+06→1000000; fix 1e+21 (was 1e21)
- String test262 subset: 45→58/100

- 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)
