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. assert semver.SemVer constructs version instances with parsed major, minor, patch, prerelease, and build metadata
  2. assert SemVer instance methods compareMain and comparePre isolate version core and prerelease comparison
  3. assert semver.compareIdentifiers compares identifier tokens by numeric precedence and ASCII lexicographical order
  4. assert semver.rcompareIdentifiers provides reverse ordering for identifier tokens
  5. assert semver.truncate shortens version numbers to major, minor, or patch resolution
  6. assert semver constants define SEMVER_SPEC_VERSION and all valid RELEASE_TYPES
