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

  1. assert semver.gtr returns true when a version is greater than every version allowed by a range
  2. assert semver.gtr returns false when a version is within or below the range or if the range is unbounded at the top
  3. assert semver.ltr returns true when a version is less than every version allowed by a range
  4. assert semver.ltr returns false when a version is within or above the range or if the range has no lower bound above 0.0.0
  5. assert semver.gtr and semver.ltr support options such as includePrerelease and loose
