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.satisfies verifies whether a version satisfies a range expression, including prerelease options
  2. assert semver.coerce parses loose or dirty strings into SemVer objects with standard and right-to-left scanning
  3. assert semver.minVersion determines the lowest version that can satisfy a given range comparator
  4. assert semver.gtr and semver.ltr test whether a version is strictly greater than or less than all versions in a range
  5. assert semver.outside determines whether a version lies above or below range bounds
  6. assert semver.prerelease extracts array components of prerelease identifiers or returns null for release versions
