 - PlayerControl works perfectly with stub BotAvatarActor
 - Must use `registerAvatar()` not `registerPlayer()` (locker needs GUID)
 
+### Known Limitations (POC)
+- **Wall shooting**: Bots can shoot through walls (no server-side collision data)
+- **No tracers**: Visual bullet trails not rendering (investigating)
+- **Random movement**: No pathfinding, just wandering
+
 ### Next Steps
-- [ ] Faction-specific spawn commands (!botnc, !bottr, !botvs) - **IN PROGRESS**
+- [x] Faction-specific spawn commands (!botnc, !bottr, !botvs) - DONE
+- [x] AI toggle (!boton / !botoff) - DONE
+- [ ] **Tower Arena Demo** - Manual coordinate capture for controlled showcase (see TOWER_DEMO.md)
 - [ ] Terrain following (Z height)
 - [ ] Bot class differentiation (loadouts will be revised for prod)
 - [ ] Population scaling (auto-spawn/despawn based on real players)
 
+### Long-term (Post-POC)
+- [ ] UBR mesh extraction for world collision
+- [ ] Navmesh generation for pathfinding
+- [ ] Proper LOS (line-of-sight) checks
