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.subset determines whether a sub-range is completely satisfied by a super-range
  2. assert semver.intersects detects whether two semver ranges share any overlapping versions
  3. assert semver.outside checks if a version lies entirely above or below a given range
  4. assert semver.Range parses complex range expressions and evaluates version matches with test
  5. assert semver.Comparator parses single comparison operators and tests versions and comparator intersections
  6. assert semver.subset and semver.intersects support options such as includePrerelease and loose
