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

  2. coerce extracts first major minor patch components from longer version strings
  3. coerce strips leading v prefix and extra prefix text
  4. coerce supports includePrerelease option to preserve prerelease tags
  5. coerce supports rtl option to parse version from right to left
  6. coerce returns null when input contains no extractable version
