  1. assert Separator is exported as a class constructor from @inquirer/prompts
  2. assert new Separator() creates an instance with default visual separator and type 'separator'
  3. assert new Separator(text) creates an instance with custom separator text and type 'separator'
  4. assert Separator.isSeparator returns true for Separator instances and objects with type 'separator'
  5. assert Separator.isSeparator returns false for non-separator choice objects and primitive values
  6. assert Separator items in choices collections can be identified and separated from selectable choices

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 @inquirer/prompts.Separator in pkg:npm/%40inquirer/prompts@6.0.1
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40inquirer/prompts@6.0.1
Demonstrate these symbols/APIs:
  - @inquirer/prompts.Separator

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.
