Tracked via the gap test suite (`test-files/test_gap_*.ts`, 28 tests). Compared byte-for-byte against `node --experimental-strip-types`. Run via `/tmp/run_gap_tests.sh` after `cargo build --release -p perry-runtime -p perry-stdlib -p perry`.

**Last full sweep:** run `./run_parity_tests.sh` for the current snapshot — the gap-suite top-line has shifted with recent landings; see open issues #447 (nested-async hang masking `test_async`), #448 (`*[Symbol.iterator]()` class hang), #449 (`new.target` → NaN), #450 (`defineProperty` accessor `this`), #451 (`test_gap_json_advanced` SIGSEGV), and #452 (`Array.fromAsync` / Proxy/Reflect / JSON ordering). Several of these are pre-existing bugs that the parity skip-list and gap-suite output truncation hid from earlier numbers.
**Last full sweep:** run `./run_parity_tests.sh` for the current snapshot. The umbrella tracker is #793 (Node.js + TypeScript compatibility roadmap); the previously-cited #447–#452 batch closed on 2026-05-04. Currently-open trackers worth knowing about:

- **Effect framework end-to-end (#321)** — `#684` (Schema.ts ~310th-init `(number).slice` regression) and `#809` (object-literal computed-keys + cross-module spread) are the live HashRing/Schema blockers.
- **Async context** — `#788` (real `AsyncLocalStorage` tracking across `await`/microtasks/timers) and `#789` (real `async_hooks.createHook` lifecycle + asyncId). Today these are name-only stubs.
- **Compile-as-package** — `#348` (ink TUI end-to-end), `#488/#489` (Drizzle + MySQL), `#678` (linker emits native callsites for V8-fallback modules).
- **Test/CI mechanics** — `#794` (per-category parity thresholds), `#796` (gap-suite output truncation + O(n²) `normalize_output`), `#812` (42-module behavioral matrix), `#806/#807/#808` (test harnesses for mixins / async context / ≥300-init scale).
- **Skip-list audit** — `#797` covers `test-parity/known_failures.json` provenance (issue # + date per entry).

**Known categorical gaps**: lookbehind regex (Rust `regex` crate), `console.dir`/`console.group*` formatting, lone surrogate handling (WTF-8).
