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. assert semver.satisfies verifies whether an exact version satisfies equality or comparator ranges
  2. assert semver.satisfies correctly evaluates caret (^) and tilde (~) range operators
  3. assert semver.satisfies correctly evaluates hyphen ranges and compound logical ranges
  4. assert semver.satisfies supports includePrerelease and loose options for range matching
  5. assert semver.satisfies returns false for invalid versions or non-matching ranges
