Dieses Netzwerk bietet eine Sache: ein Sample, das baut. Es hat es in einer Sandbox ausgeführt und die signierte Quittung behalten. Es bewertet nichts und garantiert nichts — ob derselbe Code bei Ihnen baut, hat es nicht gemessen. Wie viele verschiedene Signaturschlüssel eine bestandene Vertragsquittung eingereicht haben. Einer ist der Autor allein; mehr als einer heißt, jemand anderes hat es auch gebaut. Ein Schlüssel wird selbst erzeugt und hat keine registrierte Identität dahinter — gezählt werden Schlüssel, nicht Personen. MIT-0

Contract

  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.
