# US-005: Unlock Base III teleportation

As a **player with Base II**, I want to earn `/base` so that I can return safely to my established base.

## Acceptance criteria

- [x] Base III requires Base II, an established base, and a configurable 200 qualifying block placements inside the base.
- [x] Only placements made in Survival mode and within the base's current horizontal and vertical bounds count.
- [x] Player-placed blocks and replacement of previously broken blocks may contribute repeatedly.
- [x] Base III unlocks `/base` with a configurable 30-second warm-up and three-hour cooldown by default.
- [x] Looking around without changing block coordinates does not cancel the warm-up.
- [x] Changing block X, Y, or Z, taking damage, teleporting, changing worlds, dying, disconnecting, or starting a conflicting teleport cancels the warm-up.
- [x] Cancellation clearly informs the player and does not consume the cooldown.
- [x] The destination is a safe standing location at or near the recorded base center.
- [x] An unavailable or unsafe destination is reported clearly and does not consume the cooldown.
- [x] Only a completed teleport starts the cooldown.
- [x] Cooldowns use real elapsed time and continue while the player is offline.
