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. semver.valid validates and normalizes semver strings, returning formatted version or null
  2. semver.clean trims whitespace and strips leading prefixes
  3. semver.parse parses version strings into SemVer instances with major, minor, patch, and prerelease fields
  4. semver.inc increments versions by major, minor, patch, and prerelease release types
  5. semver.diff determines the release difference between two version strings
  6. semver.satisfies evaluates versions against caret, tilde, and comparison range expressions
  7. semver.gt, semver.lt, semver.gte, semver.lte, and semver.eq compare version precedence
  8. semver.compare and semver.rcompare sort version string arrays
  9. semver.minSatisfying and semver.maxSatisfying select the minimum and maximum versions matching a range
  10. semver.coerce parses loose version strings into valid semver representations
