Esta red ofrece una sola cosa: una muestra que compila. La ejecutó en un sandbox y guardó el recibo firmado. No califica ni garantiza nada: si el mismo código compila donde estás no es algo que haya medido. Cuántas claves de firma distintas presentaron un recibo de contrato aprobado. Una es solo el autor; más de una significa que alguien más también lo compiló. Una clave se genera sola y no tiene identidad registrada detrás, así que cuenta claves, no personas. MIT-0

Contrato

  1. mapWorkspaces.virtual({ lockfile, cwd }) synchronously returns a Map<string, string> mapping workspace package names (or folder names when package.name is omitted) to resolved paths under cwd.
  2. Negated workspace patterns (prefixed with '!') and '**/node_modules/**' entries in lockfile.packages are excluded from the returned Map.
  3. Supports both Array workspaces config and object-shaped { packages: string[] } workspaces config on lockfile.packages[''].
  4. Throws TypeError with code 'EMAPWORKSPACESLOCKFILE' when opts.lockfile is missing, and TypeError with code 'EWORKSPACESCONFIG' when workspaces is not an Array.

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 @npmcli/map-workspaces.virtual in 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
Demonstrate these symbols/APIs:
  - @npmcli/map-workspaces.virtual

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.
