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.cmp correctly evaluates equality operators (=, ==, ===, !=, !==)
  2. semver.cmp correctly evaluates relational operators (<, <=, >, >=)
  3. semver.cmp correctly compares prerelease versions
  4. semver.cmp throws TypeError for invalid comparator operators
  5. compareVersions wrapper correctly compares versions using comparison operators
