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. Document constructor creates a new YAML Document AST instance from plain JavaScript values
  2. Document.set and Document.get manipulate top-level AST entries
  3. Document.setIn and Document.getIn manipulate nested AST properties via path arrays
  4. Document.createNode and Document.createPair construct explicit AST nodes and pairs
  5. Document.toJS and Document.toString convert the AST to plain JavaScript objects and valid YAML strings
