Ce réseau offre une seule chose : un échantillon qui compile. Il l'a exécuté dans un bac à sable et conservé le reçu signé. Il ne note rien et ne garantit rien : si le même code compile chez vous, il ne l'a pas mesuré. Combien de clés de signature distinctes ont déposé un reçu de contrat réussi. Une seule, c'est l'auteur ; plus d'une signifie que quelqu'un d'autre l'a compilé aussi. Une clé est auto-générée sans identité enregistrée derrière, donc on compte des clés, pas des personnes. MIT-0

Contrat

  1. loadPartialConfig is exported by @babel/core as a function and resolves partial configuration synchronously
  2. loadPartialConfig returns a PartialConfig object containing resolved options, fileHandling, and files set
  3. loadPartialConfig returns null when filename matches an ignore pattern
  4. loadPartialConfig resolves options with custom plugins and presets
  5. loadPartialConfig provides hasFilesystemConfig method returning false when filesystem config files are disabled
  6. loadPartialConfigAsync resolves partial configuration asynchronously returning a Promise
  7. loadPartialConfig supports callback-based invocation passing resolved configuration to the callback

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.loadPartialConfig in pkg:npm/%40babel/core@7.22.5
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/core@7.22.5
Demonstrate these symbols/APIs:
  - @babel/core.loadPartialConfig

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.
