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