10 new tests: state field transitions (ready/suspended/dead), yield from
nested helper function, initial resume arg ignored by ready coroutine,
mutable closure state via dict-set!, complex yield values (list/dict),
round-robin scheduling, factory creates independent coroutines, resuming
non-coroutine raises error.
27/27 pass on both OCaml and JS.

All CEK primitives (cek-step-loop/cek-resume/make-cek-state/cek-suspended?/
cek-io-request/cek-terminal?/cek-value) were already registered in sx-browser.js.
Root cause of test failure: (import (sx coroutines)) creates an io-suspended
state when the library isn't pre-loaded; overridden cekRun throws on suspension.
Fix: pre-load spec/signals.sx + spec/coroutines.sx before test files run.
17/17 coroutine tests pass in JS. 1965/2500 total (+25 vs 1940 baseline),
zero new failures.

No native SxCoroutine type needed. dict-based coroutine identity +
cek-step-loop/cek-resume/perform/make-cek-state primitives already in
run_tests.ml fully implement the coroutine contract. 284/284 pass
(coroutines+vectors+numeric-tower+dynamic-wind), zero regressions.

spec/coroutines.sx: define-library with make-coroutine, coroutine-resume,
coroutine-yield, coroutine?, coroutine-alive?. Built on existing perform/
cek-step-loop/cek-resume suspension machinery.
spec/tests/test-coroutines.sx: 17 tests — multi-yield, final return,
arg passthrough, alive? predicate, nested coroutines, recursive iteration,
independent coroutine interleaving.
Key: coroutine body must use (define loop (fn…)) not named let — named let
transpiles to cek_call→cek_run which rejects IO suspension. All 17/17 pass.

- sx_types.ml: CallccContinuation gains winders depth int field
- sx_runtime.ml: make_callcc_continuation(captured, winders_len),
callcc_continuation_winders_len accessor; get_val maps after-thunk,
winders-len, body-result to cf_f/cf_extra/cf_name
- sx_ref.ml: step_limit/step_count restored; make_wind_after_frame and
make_wind_return_frame now store their args in the CekFrame fields
- transpiler.sx: after-thunk→cf_f, winders-len→cf_extra,
body-result→cf_name for future bootstrap runs
- 8 new dynamic-wind tests pass (OCaml), 235/235 no regressions

Add integer?/float?/exact?/inexact? predicates (Number.isInteger check).
Add truncate/remainder/modulo/random-int/exact->inexact/inexact->exact/parse-number.
inexact->exact uses Math.round (rounds to nearest, matching OCaml).
Fix sx_server.ml epoch/blob/io-response protocol to accept Integer as
well as Number — parser now produces Integer for whole-number literals.
JS: 60 new passing tests (1880→1940). OCaml: 4874/394 baseline unchanged.
Note: 6 tests fail in JS due to platform limitation (JS cannot distinguish
float 2.0 from integer 2).

- Fix PRIMITIVES["index-of"] for arrays: return NIL when not found (matching
OCaml semantics) so bind-lambda-params correctly detects absent &rest params.
Previously String(array).indexOf() returned -1, which passed number? check
and mis-fired the &rest branch, leaving non-&rest params unbound.
- Declare var _lastErrorKont_ and var hostError in IIFE scope (strict mode fix)
- Add PRIMITIVES["host-error"], ["try-catch"], ["without-io-hook"]
- Add env["test-allowed?"] stub in run_tests.js
- Add spec/tests/test-vectors.sx: 42 tests for all vector primitives
- Rebuild sx-browser.js: 1847 standard / 2362 full tests pass (up from 5)

All 10 vector primitives now have :as type annotations on every parameter,
:returns types, and :doc strings. make-vector gains optional fill annotation;
vector uses :rest for its variadic args; vector-ref/set! document bounds error.

vector-ref and vector-set! now raise Eval_error on out-of-bounds index instead of
an OCaml array exception. vector-copy accepts optional start and end parameters for
slicing (R7RS §6.8). spec/primitives.sx doc updated to reflect slice params.

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.

- 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.
