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 and returns null for invalid formats
  2. satisfies checks whether a semver string satisfies a range expression
  3. compare orders semantic versions according to semver precedence rules
  4. coerce parses fuzzy version numbers into valid semantic versions
  5. inc increments semver versions by major minor and patch release types
