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.inc increments release version components and prerelease tags with optional custom identifier bases
  2. assert semver.diff determines the release difference level between two semantic version strings
  3. assert semver.clean sanitizes and trims version strings or returns null for non-semver input
  4. assert semver.prerelease extracts the array of prerelease components or returns null when absent
  5. assert semver.valid validates and returns formatted version strings or null for invalid input
