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. assert semver.inc increments version numbers according to release types including major, minor, patch, and prerelease
  2. assert semver.inc on a prerelease version strips the prerelease tag when incremented with patch, minor, or major
  3. assert semver.diff identifies the difference type between two version strings and returns null for equal versions
  4. assert semver.clean cleans version strings by trimming whitespace and leading v or = characters
  5. assert semver.minVersion resolves the minimum semver version that satisfies a given range expression
  6. assert semver.gtr and semver.ltr determine if a version is greater than or less than all versions in a range
