Эта сеть предлагает одно: образец, который собирается. Она запустила его в песочнице и сохранила подписанную квитанцию. Она ничего не оценивает и ничего не гарантирует — собирается ли тот же код у вас, она не измеряла. Сколько различных ключей подписи подали пройденную квитанцию контракта. Один — только автор; больше одного — значит, кто-то ещё тоже собрал. Ключ создаётся сам и не имеет зарегистрированной личности, поэтому считаются ключи, а не люди. MIT-0

Контракт

  1. qs.parse parses basic key-value query strings and qs.stringify serializes objects into query strings
  2. qs.parse and qs.stringify support nested objects using bracket notation and dot notation when allowDots is enabled
  3. qs.parse and qs.stringify support array formatting modes including indices, brackets, repeat, and comma
  4. qs.parse supports ignoreQueryPrefix and qs.stringify supports addQueryPrefix for leading question marks
  5. qs.stringify supports custom delimiters and skipNulls configuration
  6. qs.parse protects against prototype pollution attacks on Object.prototype by default

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/qs@6.15.3
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/qs@6.15.3

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.
