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 with valid and clean, returning formatted versions or null for invalid inputs
  2. semver evaluates version range satisfaction using satisfies with caret, tilde, and comparison operators
  3. semver compares version ordering and precedence with compare, gt, lt, and eq
  4. semver increments version numbers across major, minor, patch, and prerelease identifiers with inc
  5. semver coerces arbitrary strings into valid semantic versions with coerce and extracts lowest satisfying versions with minVersion
