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

  2. satisfies returns false when version is outside the specified range
  3. satisfies correctly handles tilde range comparisons
  4. satisfies evaluates logical OR range expressions
  5. satisfies supports options such as includePrerelease
