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. attribute.Key constructs typed KeyValue pairs for string, integer, float64, boolean, and slice data types.
  2. attribute.Key.Defined checks whether a key name is initialized and non-empty.
  3. attribute.NewSet creates canonical deduplicated attribute collections with key-lookup semantics.
