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 collapses ranges to wildcard * when all candidate versions satisfy the range
  2. assert semver.simplifyRange simplifies compound or upper and lower bound ranges against candidate versions
  3. assert semver.simplifyRange respects includePrerelease options when simplifying ranges over prerelease versions
  4. assert semver.simplifyRange returns an empty string when no candidate versions satisfy the range
  5. assert semver.compareLoose performs loose comparison between version strings with loose formatting
