Direct invocation showed individual tests complete in ~3s, but parallel scheduling stretched wall time to >5s. Bumping to 15s makes the scoreboard usable: built-ins/String 14.1% → 65.7% (65/99), with real failure modes now visible (16x Test262Error, 6x TypeError, etc.) instead of "85x Timeout" drowning the signal. Regenerated scoreboard to reflect the new state. conformance.sh: 148/148. + - 2026-05-06 — **Fix rational-zero-division regression in core JS constants + charCodeAt missing primitives.** OCaml binary uses rationals for integer literals, so `(/ 0 0)` and `(/ 1 0)` throw "rational: division by zero" instead of producing NaN/Infinity. Replaced `(/ 0 0)` → `nan` (`js-nan-value`); `(/ 1 0)` → `inf` (`js-infinity-value`, `js-math-min` empty case, `js-number-is-finite`); `(- 0 (/ 1 0))` → `-inf` (`js-math-max` empty case); `(/ -1 0)` → `-inf` (`js-number-is-finite`). `js-max-value-approx` was looping forever (rationals never reach float infinity) — replaced with literal `1.7976931348623157e+308`. Fixed `charCodeAt` and string `.length` to use `(len s)` and `(char-code (char-at s idx))` instead of missing `unicode-len`/`unicode-char-code-at` primitives. conformance.sh: 0→148/148. Unit tests: 521/530 best run (baseline run was 417/530; both timeout-flaky). - 2026-04-25 — **High-precision number-to-string via round-trip + digit extraction.** `js-big-int-str-loop` extracts decimal digits from integer-valued float. `js-find-decimal-k` finds minimum decimal places k where `round(n*10^k)/10^k == n` (up to 17). `js-format-decimal-digits` inserts decimal point. `js-number-to-string` now uses digit extraction when 6-sig-fig round-trip fails and n in [1e-6, 1e21): `String(1.0000001)="1.0000001"`, `String(1/3)="0.3333333333333333"`.
