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. getBuiltinLowerGlobals returns array of lowercase builtin global identifiers including eval, isNaN, and undefined
  2. getBuiltinUpperGlobals returns array of uppercase builtin global identifiers including Object, Array, and Promise
  3. getBrowserUpperGlobals returns array of uppercase browser global identifiers including Window, Document, and AbortController
  4. isBuiltinGlobal returns true for standard ECMAScript globals and false for browser-only or user variables
  5. isBrowserGlobal returns true for standard browser interfaces and false for builtin-only or arbitrary names
  6. classifyGlobal accurately distinguishes lowercase builtins, uppercase builtins, browser globals, and unrecognized names
