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.

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