- Sitzungsprotokolle module: meeting protocols, agenda items, task tracking
- Verbandsverwaltung module: federation management, member clubs, contacts, fees
- Per-account module activation via Modules page toggle
- Site Builder: live CMS data in Puck blocks (courses, events, membership registration)
- Public registration APIs: course signup, event registration, membership application
- Document generation: PDF member cards, Excel reports, HTML labels
- Landing page: real Com.BISS content (no filler text)
- UX audit fixes: AccountNotFound component, shared status badges, confirm dialog,
  pagination, duplicate heading removal, emoji→badge replacement, a11y fixes
- QA: healthcheck fix, API auth fix, enum mismatch fix, password required attribute
