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.valid validates semantic version strings and returns normalized version or null for invalid inputs
  2. semver.clean cleans version strings by removing whitespace and leading prefixes
  3. semver.compare, semver.gt, and semver.lt evaluate version precedence across major, minor, and patch levels
  4. semver.satisfies evaluates whether a version satisfies caret, tilde, and comparison ranges
  5. semver.inc increments version numbers across patch, minor, major, and prerelease release types
  6. semver.coerce extracts and coerces valid SemVer versions from loose strings
  7. semver.minVersion and semver.maxSatisfying resolve boundary and best-match versions for ranges
