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

Preuves d'exécution

Contrat

  1. Instantiating JSDOM parses HTML markup and initializes window and document object models with title and body elements
  2. Standard DOM query methods querySelector, querySelectorAll, and getElementById find matching element nodes in the document
  3. Creating elements, setting attributes, modifying classList, and appending nodes dynamically updates the live DOM tree
  4. Mutating innerHTML and textContent updates child elements and text node content in real time
  5. CustomEvent creation and dispatchEvent trigger attached event listeners with bubbling and payload detail support
  6. dom.serialize() outputs the complete serialized HTML document reflecting dynamic DOM mutations
  7. JSDOM.fragment parses HTML strings into a DocumentFragment node containing the parsed child elements

PROMPT.md
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/jsdom@26.0.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/jsdom@26.0.0

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.
