National-team competitions are out
FIBA U19, UEFA U19, the IIHF world championships, Little League regional qualifiers, the World Lacrosse championships and their qualifiers, the IFAF tackle and flag world and continental championships, the ITF Masters world team championships, and in boxing the IBA and continental championships, the Youth Olympic Games and the Commonwealth Games programme. A family choosing where to enter a team cannot enter any of them, so in a directory built for that decision they are noise rather than coverage.
Club and travel-team events are in, including invitation-only ones, which are marked as such. In boxing, so are the open internationals that national squads also attend, because a club can enter those directly. In tennis the distinction runs through one fortnight: the individual world championships a player enters themselves with an ITF licence are in, and the team championships their national association enters are not.
