- The model invents, omits, or uses an outdated event
- Compare the generated list with the official schedule and regenerate from corrected source data.
- UTC conversion or all-day formatting shifts the event date
- Set the target timezone explicitly, inspect raw ICS fields, and test a small file before full import.
- All-day events block everyone’s availability
- Set TRANSP:TRANSPARENT or the calendar’s free status and confirm it after import.
- A postponed or canceled event remains on the shared calendar
- Assign an owner, retain stable event identifiers and source URLs, and publish corrections rather than importing duplicates.
