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

  1. assert Browser and BrowserPlatform define valid identifiers for browsers and platforms
  2. assert detectBrowserPlatform identifies the current execution platform
  3. assert computeExecutablePath calculates correct relative executable paths for Chrome, Firefox, and ChromeDriver across platforms
  4. assert resolveBuildId resolves build and version identifiers offline without network requests

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: resolve build id and compute executable path with @puppeteer/browsers
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40puppeteer/browsers@2.8.0
Demonstrate these symbols/APIs:
  - Browser
  - BrowserPlatform
  - computeExecutablePath
  - detectBrowserPlatform
  - resolveBuildId

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.
