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 simplifies a version range over a list of candidate versions or returns * when all versions match
  2. assert semver.cmp evaluates comparison operators including strictly equal ===, semver equal ==, greater than >, and less than or equal <=
  3. assert semver.compareLoose compares versions loosely and returns -1, 0, or 1
  4. assert semver.Comparator instantiates comparator objects with operator and semver properties and tests matching versions and intersection
  5. assert semver.Range parses range expressions into sets of comparators, formats normalized ranges, and tests version membership
