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. babel exports transformSync transformAsync parseSync traverse types and template
  2. transformSync transforms source code using custom AST visitor plugin and returns transformed code
  3. transformAsync transforms source code asynchronously returning a promise resolving to transformation result
  4. parseSync parses JavaScript source code into a Babel AST structure
  5. traverse traverses AST nodes and supports in-place node modifications
  6. types provides helper functions to check node types and build AST nodes
  7. template creates AST nodes from template strings with identifier and expression replacements
  8. transformFromAstSync generates code and source map from a Babel AST representation
