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 provides AST builder functions to construct literal nodes such as identifier, numericLiteral, stringLiteral, booleanLiteral, and nullLiteral
- types provides AST builder functions to construct complex expression nodes including binaryExpression, unaryExpression, and callExpression
- types provides AST builder functions to construct statements and declarations including variableDeclaration, variableDeclarator, and functionDeclaration
- types provides type predicate functions such as isIdentifier, isNumericLiteral, isExpression, and isStatement with optional property matching
- types provides type assertion functions such as assertIdentifier and assertNumericLiteral that throw an error on type mismatch
- types provides AST utility functions such as cloneNode to create structural duplicates and isNodesEquivalent to verify structural equality
- types provides AST utility functions such as removeProperties to strip location metadata from AST nodes
