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 and sanitize semantic version strings
  2. satisfies checks whether version satisfies a range specification
  3. compare, gt, and lt correctly order versions according to precedence
  4. inc increments versions across major, minor, patch, and prerelease types and diff finds release differences
  5. coerce extracts valid semver strings from loose version input
  6. minVersion and maxSatisfying resolve boundary versions for ranges
