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 invalid inputs
  2. clean strips whitespace and leading v or = prefixes
  3. satisfies evaluates caret, tilde, and comparator range expressions
  4. compare, gt, and lt evaluate version ordering and precedence
  5. inc increments versions across release types and diff computes release difference
  6. coerce extracts and coerces version numbers from loose string input
  7. minVersion and maxSatisfying resolve boundary versions for ranges
