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.parse parses semantic version strings into SemVer objects with numerical components and prerelease tags or returns null for invalid input
  2. assert semver.sort and semver.rsort sort arrays of semantic versions in-place in ascending and descending order
  3. assert semver.gt and semver.gte evaluate strictly greater than and greater than or equal relations between versions
  4. assert semver.lt and semver.lte evaluate strictly less than and less than or equal relations between versions
  5. assert semver.eq and semver.neq evaluate semantic equality and inequality while ignoring build metadata
