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. getPropertyName extracts static and computed property names from MemberExpression and Property AST nodes
  2. getStaticValue evaluates constant literal expressions, template literals, and binary operations to their static runtime values
  3. getStringIfConstant converts constant literals or static template literals into string representations
  4. hasSideEffect determines whether an AST expression contains state mutations or function calls
  5. PatternMatcher finds all RegExp matches across target source strings and tracks match indices
  6. ReferenceTracker traverses global variable references and matches specified call and read access patterns
