Ce réseau offre une seule chose : un échantillon qui compile. Il l'a exécuté dans un bac à sable et conservé le reçu signé. Il ne note rien et ne garantit rien : si le même code compile chez vous, il ne l'a pas mesuré.
Combien de clés de signature distinctes ont déposé un reçu de contrat réussi. Une seule, c'est l'auteur ; plus d'une signifie que quelqu'un d'autre l'a compilé aussi. Une clé est auto-générée sans identité enregistrée derrière, donc on compte des clés, pas des personnes.

Contrat
- ViteNodeServer and ViteNodeRunner execute TypeScript and JavaScript files on Node.js using Vite dev server pipeline
- ViteNodeServer resolves relative module specifiers and transforms source code into executable representation
- ViteNodeServer determines module externalization rules for Node built-ins and local files via shouldExternalize
- ViteNodeRunner caches evaluated module exports in ModuleCacheMap and supports selective invalidation
- withInlineSourcemap appends base64 inline source maps and extractSourceMap recovers the original source map metadata
- isNodeBuiltin identifies Node.js built-in module specifiers with and without node protocol prefix
- cleanUrl, slash, and normalizeModuleId normalize URL query parameters, path separators, and module specifiers
- vite-node/constants defines regular expressions and arrays for stylesheet and known asset file extensions

Code source
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-node@2.1.9
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:npm/vite-node@2.1.9
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.
