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. simplifyRange returns wildcard * when all candidate versions satisfy the range
  2. simplifyRange returns simplified bounded range for contiguous subset of versions
  3. simplifyRange returns exact single version string when only one candidate matches
  4. simplifyRange returns empty string when no candidate versions satisfy the range
  5. simplifyRange preserves caret range expressions when optimal for matching subset
  6. simplifyRange supports includePrerelease option to consider prerelease candidate versions
