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. StringUtils accurately evaluates blank and non-blank whitespace strings and performs string transformations.
  2. ArrayUtils tests element presence, array emptiness, and primitive array concatenation.
  3. Pair constructs immutable key-value tuples with typed accessors.
  4. ObjectUtils resolves non-null defaults across null and candidate argument sequences.
  5. Gradle JavaExec task compiles and executes the offline Java contract successfully.
