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.

Contrato
- temp.cleanupSync returns false when tracking is not enabled
- temp.cleanupSync returns zero deletion counts when tracking is enabled and no temporary files or directories exist
- temp.cleanupSync synchronously deletes tracked temporary files and directories returning deletion counts
- temp.cleanupSync drains tracked queues so subsequent calls return zero deletion counts
- temp.cleanupSync returns false after tracking is disabled with temp.track(false)

Código fuente
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 temp.cleanupSync in pkg:npm/temp@0.9.4
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:npm/temp@0.9.4
Demonstrate these symbols/APIs:
- temp.cleanupSync
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.
