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. valid returns null for invalid version strings
  3. valid supports loose option to sanitize prefixed or loose version strings
  4. parse returns a SemVer object with numeric major, minor, and patch properties
  5. parse extracts prerelease identifiers and build metadata
  6. parse returns null when given an invalid version string
