Coverage & sources

4 date-announced events. No fictional events or inferred recurrences. Berlin has a small local sample; Munich and Asheville have festival samples. New York City and Istanbul are unassessed. West Coast Swing is supported as a filter but currently has no verified records. No completeness benchmark has run.

Herräng 2027 is withheld because source end dates conflict. Prices and ticket inventory are not tracked.

Checks run daily when source access permits. Failed checks keep the previous evidence date. Changed or missing assertions require review. Check-needed labels appear after 72 hours for imminent events and 14 days otherwise.
