An individual profile is the starting point. Coaches and clubs become useful once the individual data has accumulated some shape. FencStats handles that progression deliberately: athletes log first, then bring a coach in through the early-access coach workspace, then optionally connect to a club through the invite-only club workspace. Each step is opt-in.
The early-access coach workspace gives a coach a view of linked athletes, those who have agreed to a coach-athlete relationship, with progress signals and bout context. It is not a global roster of every FencStats user. The relationship model is one-to-one between coach and athlete, and either side can end the relationship without affecting the athlete bout history.
Club workspace is invite-only while the team-level features mature. When it is active for a club, members get a shared context, admins can manage rosters and approve join requests, and coaches can be associated with the club. None of that overrides the underlying privacy model on individual profiles, clubs see member-level context, not unfiltered bout dumps.
