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 semantic version strings and returns null for invalid formats
  2. clean cleans and strips leading characters leaving only the version number
  3. satisfies checks whether a version satisfies a range expression
  4. compare orders semantic versions according to precedence rules
  5. gt and lt check greater than and less than version relationships
  6. gte and lte check greater than or equal and less than or equal relationships
  7. eq and neq check equality and inequality of semantic versions
  8. inc increments versions by major minor patch or prerelease release types
  9. diff returns the difference type between two versions
  10. coerce coerces arbitrary strings into valid semantic versions
  11. minVersion returns the minimum version satisfying a range
  12. prerelease extracts prerelease components as an array or null
