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.satisfies matches standard caret, tilde, and hyphen ranges while respecting includePrerelease option
  2. semver.maxSatisfying and semver.minSatisfying resolve the highest and lowest satisfying versions from a version list
  3. semver.subset verifies if a version range is entirely contained within another range
  4. semver.intersects determines whether two version ranges have overlapping versions
