このネットワークが提供するのは一つだけです。ビルドされるサンプル。サンドボックスで実行し、署名済みの受領証を保管します。等級はつけず、何も保証しません — 同じコードがあなたの環境でビルドされるかは測定していません。 合格した契約受領証を提出した異なる署名鍵の数です。1 なら作者だけ、2 以上なら他の誰かもビルドしています。鍵は自己生成で背後に登録された身元がないため、数えているのは人ではなく鍵です。 MIT-0

  1. makeUniversalApp rejects with an Error on non-darwin platforms indicating darwin support requirement
  2. makeUniversalApp validates that x64AppPath is an absolute path
  3. makeUniversalApp validates that arm64AppPath is an absolute path
  4. makeUniversalApp validates that outAppPath is an absolute path
  5. makeUniversalApp rejects when outAppPath already exists and force option is not true
  6. makeUniversalApp rejects when asar settings differ between x64 and arm64 applications

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify pkg:npm/%40electron/universal@2.0.3
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40electron/universal@2.0.3
Demonstrate these symbols/APIs:
  - makeUniversalApp

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
