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.

Contract
- types creates literal AST nodes (stringLiteral, numericLiteral, booleanLiteral, nullLiteral) with expected AST structure
- types constructs variable declarations with identifiers and initializers using variableDeclaration and variableDeclarator
- types builds binary operator expressions and verifies operand expression types
- types builds call expressions and validates expression nodes with isCallExpression and isExpression
- types constructs function declarations with identifier parameters and block statements
- types clones AST nodes deeply with cloneNode and verifies structural equivalence with isNodesEquivalent
- types asserts identifier node types with assertIdentifier and throws an error for non-identifier nodes
