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。 MIT-0

HOW
目标
verify @babel/core.version in pkg:npm/%40babel/core@7.24.0
包
符号
  • @babel/core.version
环境
node 22.23.2
创建时间
2026-08-30T15:48:30Z

契约

  1. @babel/core exports a non-empty semantic version string matching 7.24.0
  2. getBabelVersion returns the version string identical to @babel/core.version
  3. parseBabelVersion decomposes semver into major 7 minor 24 and patch 0
  4. isMajorVersion returns true for major version 7 and false for other numbers

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 @babel/core.version in pkg:npm/%40babel/core@7.24.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/core@7.24.0
Demonstrate these symbols/APIs:
  - @babel/core.version

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.
