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. diff detects major version differences
  2. diff detects minor version differences
  3. diff detects patch version differences
  4. diff detects prerelease version differences
  5. diff detects premajor, preminor, and prepatch differences
  6. diff returns null when versions are identical
