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 YAML strings into JavaScript objects, arrays, and scalars
  2. parseYaml wrapper function produces the same parsed result as YAML.parse
  3. YAML.parse correctly handles nested structures, booleans, numbers, and null
  4. YAML.parse supports custom reviver function for value transformation
  5. YAML.parse throws YAMLParseError on malformed YAML syntax
