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。

コントラクト
- By default (ignoreGlobal: false), references to the global identifier in CommonJS modules are rewritten to the commonjsGlobal helper variable.
- Setting ignoreGlobal: true preserves references to the global identifier without rewriting them to commonjsGlobal.
- When ignoreGlobal: true, the commonjsGlobal helper definition is omitted from the bundled output if no other features require it.
- A module containing only the global identifier without module, exports, or require is recognized and transformed as CommonJS by default, but is treated as a standard non-CommonJS module when ignoreGlobal: true.
- Setting ignoreGlobal: true preserves top-level this references without rewriting them to commonjsGlobal or module exports.

ソース
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 ignoreGlobal in pkg:npm/%40rollup/plugin-commonjs@28.0.2
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:npm/%40rollup/plugin-commonjs@28.0.2
Demonstrate these symbols/APIs:
- ignoreGlobal
Constraints:
- executionContext: node
Required runtime conditions:
- ecosystem: npm
- language: javascript
- moduleSystem: cjs
- runtime: node@22.23.2
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.
