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. visit traverses YAML AST nodes including Map, Seq, Pair, and Scalar
  2. visit modifies Scalar node values during AST traversal
  3. visit removes nodes from collections when returning visit.REMOVE
  4. visit stops AST traversal when returning visit.BREAK
  5. visit skips child nodes when returning visit.SKIP
