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. Root export returns the built-in Object constructor reference
  2. isObject returns true for plain objects, arrays, functions, regular expressions, null-prototype objects, and Date instances
  3. isObject returns false for primitive values including null, undefined, numbers, strings, booleans, symbols, and bigints
  4. RequireObjectCoercible throws a TypeError when passed null or undefined
  5. RequireObjectCoercible accepts an optional custom error message as the second argument
  6. RequireObjectCoercible returns the input value unmodified for non-nullish primitives and objects
  7. ToObject throws a TypeError when passed null or undefined
  8. ToObject returns objects, arrays, and functions unchanged by reference
  9. ToObject converts primitive values (numbers, strings, booleans, symbols) into boxed Object instances
  10. toObjectSafe validates coercibility before converting input to Object
