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. simplifyRange simplifies contiguous lower-bounded ranges into single comparison operators like '>='
  3. simplifyRange simplifies contiguous upper-bounded ranges into single comparison operators like '<='
  4. simplifyRange preserves minimal exact versions or bounded expressions for specific version subsets
  5. simplifyRange returns empty string when no provided version matches the range or for invalid ranges
  6. simplifyRange respects options including includePrerelease for prerelease version sets
