# US-003: Show progression and rank advancement
As a **player**, I want visible progress and rank-up notifications so that I understand my advancement without persistent screen clutter.
## Acceptance criteria
- [ ] After each qualifying creeper kill, a temporary boss bar shows the player's current state and progress toward the next rank.
- [ ] A locked player sees progress toward Creeper Aura I.
- [ ] A ranked player sees their current Roman-numeral rank, current kill total, and the next threshold.
- [ ] The display duration is configurable and defaults to a short period measured in seconds.
- [ ] The boss bar is hidden automatically when its display period expires.
- [ ] A rank VI player no longer sees a progress boss bar.
- [ ] Each newly attained rank displays a full-screen title naming the rank.
- [ ] Joining the server does not replay a previously acknowledged rank-up title.
- [ ] Administrative progress changes update the display state of an online affected player.
- [ ] When one progress event satisfies multiple ranks, the resulting rank and notification behavior is deterministic and tested.
