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 version strings
  2. clean trims whitespace and leading prefix characters from version strings
  3. satisfies evaluates whether a version satisfies a semver range
  4. gt compares two semver versions for precedence
  5. inc increments semver version according to release types
  6. coerce parses semver versions from loose or unformatted input strings
