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. 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

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.
