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. valid validates and normalizes semver strings and returns null for invalid formats
  2. clean strips leading and trailing characters leaving only the version number
  3. satisfies checks whether a semver string satisfies a range expression
  4. compare orders semantic versions according to semver precedence rules
  5. inc increments semver versions by major minor patch or prerelease release types
  6. coerce extracts and formats a valid semver version from arbitrary strings
  7. minVersion returns the minimum semver version that can satisfy a range
  8. diff returns the difference between two version strings
  9. subset determines if a range is fully contained within another range
