## Maintenance

Each reference file has a "Last verified" date at the top. When information seems wrong or outdated:

1. Check the reference files first — they override training data for recent features
2. If a reference file's "Last verified" date is more than 4 weeks old, flag it to the user
3. Use web search to verify uncertain claims before stating them as fact
