# US-001: Unlock and establish Base I

As a **player**, I want to earn and set a personal base so that later quality-of-life progression has a location associated with it.

## Acceptance criteria

- [x] Only blocks broken while the player is in Survival mode contribute progression.
- [x] Breaking `GRASS_BLOCK` or `DIRT` contributes one unit of Base I progress.
- [x] Other dirt-like materials, including coarse dirt, rooted dirt, podzol, mycelium, and dirt paths, do not contribute by default.
- [x] Player-placed blocks may contribute when broken; natural-generation detection is not required.
- [x] Base I unlocks when the player reaches the configured threshold, which defaults to 250 qualifying blocks.
- [x] `/setbase` is unavailable before Base I and explains the unmet requirement.
- [x] `/sethome` is an alias for `/setbase` with identical behavior.
- [x] After Base I unlocks, `/setbase` records the player's current world and block location as the center of a cylindrical base.
- [x] The initial cylinder has a configurable 10-block horizontal radius and extends a configurable 25 blocks above and 25 blocks below the set Y coordinate.
- [x] The first successful `/setbase` is immediately available.
- [x] A successful relocation starts a configurable elapsed-time cooldown that defaults to 24 hours.
- [x] Failed attempts do not start or extend the relocation cooldown.
- [x] Progress and base state are associated with the player's UUID and survive restarts.
