- 2026-04-23 (session 3, continued) — **Scoreboard scoped 100/cat**: Math 40% / Number 43% / String 31% = 114/300 overall. Additional commits (85a329e8..c3b0aef1):
- `fn.length` reflects arity via `lambda-params` + `js-count-real-params`. Math.abs.length = 1 etc.
- `Object` global now callable (`new Object()`, `Object(5)`). Object.prototype has `hasOwnProperty`/`isPrototypeOf`/`propertyIsEnumerable`/`toString`/`valueOf`.
- Function receivers inherit Object.prototype builtins via `js-invoke-function-objproto`. `String.prototype.toUpperCase.hasOwnProperty('length')` works.
- `globalThis` → `js-global`; `eval` → `js-global-eval` (no-op stub); `Function` global stub (constructor throws TypeError, prototype populated).
- `URIError` and `EvalError` constructors.

1. `test262-runner.py` rewritten with `multiprocessing.Pool` for `--workers N` shards; raw-fd line buffer replaces thread-per-line. Auto-defaults 1 worker on <=2-core machines (parallel slower on this box — OCaml CPU-bound, 2 processes starve). Classifier maps parser errors to SyntaxError so negative-SyntaxError tests pass instead of failing. 1. `test262-runner.py` rewritten with `multiprocessing.Pool` for `--workers N` shards; raw-fd line buffer replaces thread-per-line.

2. `Function.prototype.call/apply/bind` via `js-invoke-function-method`, dispatched in `js-invoke-method` when recv is a function. `fn.name/.length` also exposed. 2. `Function.prototype.call/apply/bind` via `js-invoke-function-method`, dispatched in `js-invoke-method` when recv is a function. `fn.name/.length` also exposed.
