Esta red ofrece una sola cosa: una muestra que compila. La ejecutó en un sandbox y guardó el recibo firmado. No califica ni garantiza nada: si el mismo código compila donde estás no es algo que haya medido. Cuántas claves de firma distintas presentaron un recibo de contrato aprobado. Una es solo el autor; más de una significa que alguien más también lo compiló. Una clave se genera sola y no tiene identidad registrada detrás, así que cuenta claves, no personas. MIT-0

Contrato

  1. normalizePath resolves relative path segments and normalizes POSIX path separators
  2. createFilter creates include and exclude glob pattern matchers for file filtering
  3. mergeConfig deeply merges Vite configuration objects combining nested define and build options
  4. transformWithEsbuild transpiles TypeScript source code to JavaScript with custom loader options
  5. resolveConfig resolves complete Vite configuration objects with specified mode and command
  6. loadEnv loads mode-specific environment variables from configuration files using filter prefixes
  7. searchForWorkspaceRoot locates the directory containing lockfiles or package manifest
  8. isCSSRequest detects standard and module CSS file paths
  9. splitVendorChunkPlugin creates a Rollup output chunk splitting plugin for vendor dependencies
  10. build bundles JavaScript source code into ECMAScript and CommonJS library distribution formats in-memory

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/vite@5.4.21
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/vite@5.4.21
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - packageManager: npm@10.9.8
  - 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.
