コントラクト

  1. loadPartialConfigAsync returns a Promise resolving to a PartialConfig object containing options and fileHandling
  2. loadPartialConfigAsync merges provided inline configuration options such as sourceMaps and minified
  3. loadPartialConfigAsync resolves to null when the target file matches an ignore pattern
  4. loadPartialConfigAsync rejects with an Error when invalid or unknown options are provided
  5. loadPartialConfigAsync normalizes plugin declarations into ConfigItem objects within options.plugins

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.loadPartialConfigAsync 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.loadPartialConfigAsync

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.
