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. MIT-0

Contrat

  1. suggestOption returns formatted 'Did you mean "<suggestion>"?' message when unrecognized option has Levenshtein distance < 3 to an allowed option
  2. suggestOption returns an empty string when no allowed option is within Levenshtein distance < 3
  3. suggestOption selects the first matching suggestion when multiple allowed options are within distance threshold
  4. suggestOption handles exact match by returning did you mean suggestion with edit distance 0

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 jest-validate.createDidYouMeanMessage in pkg:npm/jest-validate@30.4.1
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/jest-validate@30.4.1
Demonstrate these symbols/APIs:
  - jest-validate.createDidYouMeanMessage

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.
