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. SymbolTree instantiates and manages tree relations on objects using Symbol properties
  2. appendChild, prependChild, insertBefore, and insertAfter manipulate node hierarchy and sibling pointers
  3. childrenToArray, ancestorsToArray, and treeToArray serialize tree structures in traversal order
  4. childrenIterator iterates over child elements in sequence
  5. compareTreePosition computes relative tree position flags according to DOM tree order
  6. remove unlinks an object from its parent and sibling chain updating adjacent references
