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.gt and semver.lt perform relational comparisons between version strings adhering to semver precedence
  2. assert semver.compare and semver.rcompare compare two versions and return integer sorting order
  3. assert semver.compareBuild evaluates build metadata differences where semver.compare treats them as equal
  4. assert semver.sort and semver.rsort sort arrays of version strings in ascending and descending precedence order
  5. assert semver.major, semver.minor, and semver.patch extract numeric version components from parsed version strings
  6. assert semver.prerelease extracts an array of prerelease components or returns null when no prerelease tag is present
  7. assert semver.maxSatisfying and semver.minSatisfying filter version arrays and return highest and lowest matching versions for a range
  8. assert semver.valid sanitizes and returns canonical version strings or null for invalid semver input and semver.validRange validates range strings
