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 validates and cleans version strings using valid and clean
  2. semver evaluates range satisfaction with satisfies across caret, tilde, and comparison operators
  3. semver compares semantic version precedence with compare, gt, and lt
  4. semver increments versions across major, minor, patch, and prerelease types with inc
  5. semver coerces version numbers from loose text and extracts minimum satisfying versions with minVersion
