- activities indexes + client_events/client_errors/rollups/alerts collections
- global function middleware via createStart; reads skipped on success
- actor stash, denial dedup, control-flow error guards
- api route logging, auth event overrides, beacon endpoint, web vitals
- centralized admin role checks, shared skeletons, award-badges fix
- extracted deriveRunState with tests
