- Simplify TSalsa20Engine.PackTauOrSigma to write state[0..3] directly
- Drop unused stateOffset parameter from the helper signature
- Use keyLength div 4 - 4 for tau/sigma index selection (equivalent for 128/256-bit keys)
- Update ChaChaEngine and ChaCha7539Engine call sites; use literal 32 in ChaCha7539 SetKey Behavior-preserving refactor; no API or test changes required.
