이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다. 통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다. MIT-0

컨트랙트

  1. mapWorkspaces({ cwd, pkg }) resolves workspace glob patterns (both array and { packages: [...] } forms), respects negated patterns (!pattern), falls back to folder name when package.json omits name, and returns a Map<packageName, directoryPathname> in pattern declaration order
  2. mapWorkspaces rejects with Error code EDUPLICATEWORKSPACE when multiple workspace directories share the same package name
  3. mapWorkspaces rejects with TypeError code EMAPWORKSPACESPKG when opts.pkg is missing and TypeError code EWORKSPACESCONFIG when workspaces is not an Array
  4. mapWorkspaces.virtual({ cwd, lockfile }) synchronously maps workspace entries from a lockfile packages object into a Map<packageName, directoryPathname> and throws TypeError code EMAPWORKSPACESLOCKFILE when opts.lockfile is missing

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/%40npmcli/map-workspaces@4.0.2
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40npmcli/map-workspaces@4.0.2

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.
