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 semantic version strings and rejects non-semver patterns or incomplete tuples
  2. clean strips whitespace and leading v or = prefixes from version strings
  3. satisfies evaluates caret, tilde, comparator, and compound ranges with prerelease options
  4. gt, lt, eq, and compare evaluate version precedence and equivalence across major, minor, patch, and prerelease tags
  5. coerce extracts and coerces valid SemVer versions from loose strings
  6. minVersion resolves the minimum matching SemVer version for range expressions
