Maintenance
Each reference file has a "Last verified" date at the top. When information seems wrong or outdated:
- Check the reference files first — they override training data for recent features
- If a reference file's "Last verified" date is more than 4 weeks old, flag it to the user
- Use web search to verify uncertain claims before stating them as fact
