node-suite parity audit on macOS arm64: 577 non-PASS results, including 24 crashes

[TheHypnoo]

What happened

A complete local run of Perry's canonical Node compatibility suite on an Apple M1 Pro completed all 4,376 fixtures and produced 577 non-PASS results, including 24 crashes.

The command exited successfully because the aggregate parity rate remained above the current 80% threshold, even though the run contained 9 SIGSEGVs, 15 timeouts, and 7 compile failures. This issue records the full reproducible baseline so the failures can be triaged by causal cluster rather than as isolated fixtures.

What you expected

The complete node-suite run should provide a trustworthy compatibility gate:

• every selected fixture is adjudicated against the pinned Node oracle;
• crashes, timeouts, compile failures, and oracle failures are visible and fail the gate independently of the aggregate percentage;
• the committed baseline and the canonical harness use the same execution contract;
• failures can be tracked module-by-module from a reproducible report tied to a specific commit and environment.

Minimal reproduction

This is intentionally the full suite, not a minimized single-runtime bug:

env \
  -u PERRY_SKIP_BUILD \
  -u PERRY_BIN \
  -u PERRY_RUNTIME_DIR \
  -u PERRY_NO_AUTO_OPTIMIZE \
  PATH="$PWD/.cache/node-pin/26.5.1/node-v26.5.1-darwin-arm64/bin:$PATH" \
  ./run_parity_tests.sh \
    --suite node-suite \
    --journal /tmp/perry-node-suite-fresh.jsonl

No --module, --filter, --shard, or --resume option was used. The script performed a normal fresh build before running the suite.

Environment

• Host: MacBook Pro (MacBookPro18,3), Apple M1 Pro, 10 CPU cores, 16 GB RAM
• Host OS: macOS 26.6.1 (25G76), arm64
• Target: native macOS arm64
• Rust toolchain: rustc 1.100.0-nightly (f7d782a3b 2026-08-19)
• Installed via: built from source by the parity harness

• Repository state: clean before and after the run

Diagnostic output

Overall result

Outcome	Count
PASS	3,799
Parity failure	546
Compile failure	7
Crash	24
Node/oracle failure	0
Skipped	0
Total	4,376
Non-PASS	577
Success over all selected fixtures	86.8%
Percentage reported by the harness	86.9%

The harness reports 86.9% because compile_fail is excluded from its denominator. It exits with status 0 because the result remains above the 80% threshold.

Observed classes:

• http/exports/event-constructors fails because Perry does not export CloseEvent from node:http.
• worker_threads/worker-lifecycle/url-eval-validation fails while parsing generated worker eval code with TS1109.

Baseline and gate observations

1. run_parity_tests.sh exits successfully with 24 crashes and 7 compile failures because only the aggregate 80% threshold controls its final status.
2. test-parity/known_failures.json has no node-suite/* entries, so its macOS audit classifies all 577 non-PASS results as new.
3. The committed node_suite_baseline.json was generated with scripts/node_suite_run.py, while this run used the canonical run_parity_tests.sh harness. The runners do not currently share an identical execution contract, so floor/ceiling comparisons are only directional.
4. Compared directionally with the committed baseline, PASS floors are lower for assert, cluster, dgram, domain, events, and http2; crash ceilings are exceeded for dns, http2, https, and net.

Suggested triage order

1. Treat SIGSEGVs, timeouts, and compile failures as hard gate failures independent of aggregate parity.
2. Triage shared runtime classes before individual fixtures: worker_threads lifecycle/transfer, async network lifecycle, and EventEmitter/domain prototype identity.
3. Generate the committed node-suite baseline with the same canonical harness and pinned Node version used by the gate.
4. Split confirmed causal clusters into implementation issues, keeping this issue as the reproducible full-suite baseline.

Anything else

This is distinct from the top-level test-files/*.ts parity audit in #8271. This report covers only the complete test-parity/node-suite/**/*.ts corpus selected by --suite node-suite.
