  1. sanitizePath normalizes path separators, strips Windows drive letters, and removes leading slashes and relative parent components
  2. unixifyPath normalizes path separators to forward slashes and strips Windows drive letters
  3. trailingSlashIt appends a trailing forward slash if the path string does not end with one
  4. dateify parses date strings or converts values into Date instances
  5. isStream returns true for readable and writable stream instances and false for non-stream objects
  6. normalizeInputSource converts strings and null into Buffer instances and pipes Stream instances through PassThrough
  7. collectStream buffers readable stream chunks and returns a complete Buffer via callback
  8. lazyReadStream returns a lazy readable stream instance for the given filepath
  9. file.exists synchronously checks if joined file paths exist
  10. file.expand matches wildcard glob patterns synchronously
  11. walkdir asynchronously traverses directories and collects file stats and relative paths

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/archiver-utils@3.0.4
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/archiver-utils@3.0.4

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.
