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.compare sorts version strings in ascending order and semver.rcompare sorts in descending order with prerelease precedence
  2. assert semver.maxSatisfying returns the highest satisfying version in a candidate list or null
  3. assert semver.minSatisfying returns the lowest satisfying version in a candidate list or null
  4. assert semver.intersects checks if two semver ranges have overlapping satisfying versions
  5. assert semver.subset verifies if a semver range is entirely contained within another range
