Контракт

CommonJS dynamic require calls fail at runtime with an error prompting configuration of dynamicRequireTargets when dynamicRequireTargets is not configured.
Configuring dynamicRequireTargets with glob patterns bundles matching CommonJS modules into the dynamic module registry and allows dynamic require calls to successfully resolve and execute them at runtime.
Dynamic require calls across multiple target modules correctly preserve exported functions, objects, and return values.
Negation glob patterns prefixed with '!' in dynamicRequireTargets exclude specified modules from being bundled, causing dynamic require calls for those excluded files to throw an error.
Dynamic require calls targeting unconfigured or nonexistent file paths throw an error indicating the file could not be dynamically required.

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 dynamicRequireTargets in pkg:npm/%40rollup/plugin-commonjs@28.0.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40rollup/plugin-commonjs@28.0.7
Demonstrate these symbols/APIs:
  - dynamicRequireTargets
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - packageManager: npm@10.9.8
  - runtime: node@22.23.2

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.
