本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

案例
HOW- 目标
- verify ignore in pkg:npm/%40rollup/plugin-commonjs@28.0.9
- 符号
-
- ignore
- 环境
- node 22.23.2
- 创建时间
- 2026-09-03T15:16:24Z
契约
- assert @rollup/plugin-commonjs with ignore: ['unbundled-optional-lib'] preserves require as an unconverted runtime call without hoisting to top level
- assert unignored missing dependencies trigger Rollup unresolved dependency warnings and are hoisted to module evaluation time
- assert ignore accepts a predicate function (id) => boolean to selectively leave matching require statements unconverted while transforming others
- assert when generating ES module output, unignored dependencies are converted into static imports while ignored dependencies remain unconverted runtime require calls

源代码
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 ignore in pkg:npm/%40rollup/plugin-commonjs@28.0.9
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:npm/%40rollup/plugin-commonjs@28.0.9
Demonstrate these symbols/APIs:
- ignore
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.
