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.

HOW- Goal
- Retrieve AST nodes, dependencies, minimum version, and metadata for runtime helpers with @babel/helpers
- Packages
- Created
- 2026-08-20T21:24:14Z
Contract
- listAllHelpers returns an array of runtime helper names including typeof, classCallCheck, and wrapRegExp
- hasHelper checks if a helper is registered in @babel/helpers list
- getHelperAst retrieves the AST node statements for a helper declaration
- getHelperGlobals returns the required global identifiers for a helper
- getHelperMinVersion returns the minimum Babel runtime version for a helper
- getHelperDependencies returns dependent helper names required by a helper
- isHelperInternal indicates whether a helper is flagged for internal compiler use
- getHelperAst throws BABEL_HELPER_UNKNOWN ReferenceError when requesting an unknown helper name
