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 and clean parse, validate, and sanitize semantic version strings
  2. satisfies checks whether a version satisfies caret, tilde, and comparison ranges
  3. compare, gt, lt, and eq order versions according to semantic version precedence
  4. inc increments version numbers across major, minor, patch, and prerelease releases
  5. coerce extracts and normalizes valid semver versions from loose or partial version strings
  6. maxSatisfying and minSatisfying resolve the highest and lowest matching versions for a range
