컨트랙트

plugin exports a Babel plugin declaration function
plugin returns a plugin object with name transform-duplicate-named-capturing-groups-regex and RegExpLiteral visitor
plugin transforms duplicate named capturing groups into numbered groups wrapped with runtime helper
transformed regex correctly populates named capture groups for both branches during exec and match
transformed regex supports multiple duplicate named groups across alternation branches
transformed regex supports string replacement using named capture group syntax
transformed regex supports function replacement receiving named capture groups
plugin leaves regular expressions without duplicate named capturing groups untouched

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/plugin-transform-duplicate-named-capturing-groups-regex@8.0.1
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/plugin-transform-duplicate-named-capturing-groups-regex@8.0.1
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - 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.
