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. assert isMap, isSeq, isScalar, and isPair identify parsed YAML AST node types
  2. assert doc.createAlias creates an Alias AST node referencing an anchored collection node
  3. assert doc.createAlias generates unique anchor names when anchor name is omitted
  4. assert isAlias identifies parsed Alias nodes and resolves referenced values on toJS
  5. assert isAlias, isMap, isSeq, isScalar, and isPair correctly distinguish instantiated AST nodes
  6. assert createDocumentWithAnchor attaches manual anchors to target nodes and serializes valid YAML
