  1. getModuleName resolves module names based on options, root configs, and custom getModuleId functions
  2. isSideEffectImport identifies whether import metadata represents an import with no specifiers
  3. hasExports reports whether the module metadata contains export declarations
  4. isModule identifies whether program AST node has module source type
  5. ensureStatementsHoisted marks statement AST nodes with the _blockHoist metadata property
  6. buildDynamicImport transforms dynamic import AST nodes using a custom transform 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 pkg:npm/%40babel/helper-module-transforms@8.0.1
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/helper-module-transforms@8.0.1

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.
