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 semantic version strings
  2. semver checks range satisfaction with comparison operators and wildcards
  3. semver compares version precedence accurately with gt, lt, and compare
  4. semver increments versions across major, minor, patch, and prerelease types
  5. semver coerces version strings and finds minimum satisfying versions
