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.simplifyRange produces the shortest equivalent range expression matching the same subset of given versions
  2. assert semver.toComparators splits a range into a two-dimensional array of comparator string tuples
  3. assert semver.outside returns true when a version is outside a range in the specified direction ('<' or '>')
  4. assert semver.outside returns false when a version satisfies the range or lies on the opposite side of the tested direction
  5. assert semver.minSatisfying returns the lowest version in a list satisfying a given range or null if none match
