## Processes
1. **Auth** — login, account validation, channel list
2. **Game** — world, movement, combat, inventory, shops (per core feature set)
3. **DB** — accounts, players, items persistence
4. **Cache** — session / live world shared state
## Data layers for “items / skills / maps”
| Layer | Where |
|-------|--------|
| Protocol packets | Core source (`vendor/*/src`) |
| Item/mob definitions | Core data JSON/SQL + client proto packs |
| Skills | Core skill managers + client skill data |
| Maps | Map files client-side + spawn/atlas server-side |
| Play handling | Game server combat/move services |
## Two cores included
- **QCX** — production-style Docker images from GHCR, C#
- **Open-MT2** — Node/TS, rich roadmap UI, easier to read for packet study
Pick one primary for runtime; keep the other as reference.
