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. YAML.parse parses simple key-value YAML strings into JavaScript objects
  2. YAML.parse parses nested structures, arrays, and primitive data types (strings, numbers, booleans, null)
  3. YAML.parse supports custom reviver functions to transform parsed values
  4. YAML.parse throws a YAMLParseError when parsing syntactically invalid YAML strings
