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 evaluates exact and comparative version ranges (caret, tilde, and comparison operators)
  2. semver.satisfies supports range sets with logical OR (||) and whitespace-separated AND conditions
  3. semver.satisfies rejects prerelease versions unless includePrerelease option is true
  4. semver.satisfies supports loose version and range parsing with loose option
  5. satisfies is directly importable from semver/functions/satisfies
  6. semver.satisfies returns false for invalid versions or ranges without throwing
  7. isVersionSatisfied wrapper function accurately checks range satisfaction
