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. semver validates and cleans version strings using semver.valid and semver.clean, returning normalized versions or null for invalid inputs
  2. semver checks whether versions satisfy range specifications using semver.satisfies across carets, tildes, and comparison operators
  3. semver compares semantic version precedence using semver.compare, semver.gt, and semver.lt
  4. semver increments versions across major, minor, patch, and prerelease release types using semver.inc
  5. semver coerces loose version strings using semver.coerce and extracts minimum satisfying versions using semver.minVersion
  6. semver determines version differences using semver.diff and finds highest satisfying versions using semver.maxSatisfying
