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.valid validates semantic version strings and rejects non-semver patterns or incomplete tuples
  2. assert semver.clean strips whitespace and leading 'v' or '=' prefixes from version strings
  3. assert semver.satisfies evaluates caret, tilde, and comparison ranges without matching prereleases unless includePrerelease is set
  4. assert semver.gt, semver.lt, and semver.eq evaluate version precedence and equivalence across major, minor, patch, and prerelease tags
  5. assert semver.coerce extracts and coerces version numbers from loose strings into SemVer instances
  6. assert semver.minVersion resolves the minimum matching SemVer version for range expressions
