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
  2. assert semver.clean strips whitespace and leading 'v' or '=' prefixes from version strings
  3. assert semver.satisfies evaluates caret, tilde, and comparison ranges with options
  4. assert semver.gt, semver.lt, and semver.compare evaluate version precedence and equivalence
  5. assert semver.inc increments versions across major, minor, patch, and prerelease types
  6. assert semver.coerce extracts and coerces version numbers from loose strings
  7. assert semver.minVersion and semver.maxSatisfying resolve boundary versions for ranges
