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. minVersion resolves the lowest satisfying version for comparison, caret, tilde, and hyphen ranges
  2. minVersion increments patch version for exclusive greater-than ranges
  3. minVersion returns 0.0.0 for wildcard, empty, and upper-bounded ranges
  4. minVersion selects the lowest bound across multiple union ranges
  5. minVersion preserves prerelease tags when evaluating prerelease ranges
  6. minVersion returns a SemVer instance or null for unsatisfiable ranges
  7. minVersion is directly importable from semver/ranges/min-version
  8. minVersion throws TypeError when provided with an invalid range string
