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 checks basic comparisons and exact version matching
  2. semver.satisfies supports caret and tilde ranges
  3. semver.satisfies handles hyphen ranges and wildcards
  4. semver.satisfies handles prerelease versions with includePrerelease option
  5. semver.satisfies returns false for invalid versions or non-matching inputs
