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. parse parses YAML strings into JavaScript objects, arrays, and primitive values
  2. stringify serializes JavaScript objects and nested structures into YAML formatted strings
  3. parse supports custom options such as schema types and reviver transform functions
  4. stringify supports formatting options such as indent width and replacer filtering
  5. parse and stringify preserve data integrity across serialization and deserialization round trips
