Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. DOM scripts evaluated in GlobalWindow run in host globalThis without a VM context, causing unqualified window references to throw ReferenceError rather than resolving the window instance
  2. GlobalWindow shares host ECMAScript prototypes and constructors including Array, Object, and Promise with globalThis while Window uses a separate VM realm
  3. GlobalWindow preserves instance-bound Happy DOM implementations for Web platform APIs such as URL, Request, and setTimeout rather than replacing them with host Node globals
  4. happyDOM.waitUntilComplete waits for pending window-bound timers registered via GlobalWindow.prototype.setTimeout
