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. valid validates and normalizes semver strings
  2. clean trims whitespace and strips leading 'v' or '=' prefixes
  3. satisfies checks if version satisfies semver range expression
  4. gt compares two versions and returns true if first is greater than second
  5. inc increments version according to release type
  6. coerce extracts a valid semver version from arbitrary string
