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
- parse parses YAML mapping into a JavaScript object
- parse parses YAML sequences into a JavaScript array
- parse supports reviver function to transform parsed values
- parse converts integers to BigInt when intAsBigInt is true
- stringify serializes a JavaScript object into formatted YAML string
- stringify supports custom indent and formatting options
- stringify supports replacer function to filter or modify values
- round-trip serialization and deserialization preserves data fidelity
