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. semver.diff returns major for differences in the major version component
  2. semver.diff returns minor for differences in the minor version component
  3. semver.diff returns patch for differences in the patch version component
  4. semver.diff returns premajor, preminor, and prepatch when comparing stable to prerelease versions of future releases
  5. semver.diff returns prerelease when only the prerelease identifier changes
  6. semver.diff returns null when versions are equal or only build metadata differs
  7. semver.diff throws TypeError when given invalid version strings
