Manager Priorities
- Label older details as inherited until current testing confirms them.
- Keep historical names searchable.
- Record a current change instead of overwriting the older evidence.
Common Management Mistake
Presenting every older table as a confirmed 2026 rule would make the guide look complete while reducing its reliability.
Key Takeaways
- The 2019 and 2021 official guides remain valuable historical evidence, but they are not automatic proof of identical 2026 behavior.
- Label older details as inherited until current testing confirms them.
- Presenting every older table as a confirmed 2026 rule would make the guide look complete while reducing its reliability.
