# US-018: Control Pocket Base mob spawning

As a **Pocket Base owner**, I want to enable or disable natural mob spawning in my Pocket Base so that I can choose whether the private world supports normal mob activity.

## Acceptance criteria

- [x] Natural mob spawning is disabled by default in every new Pocket Base and in existing Pocket Bases that have no saved preference.
- [x] A Pocket Base owner can use `/basesettings pocket mobs enable|disable` to control natural mob spawning in their own Pocket Base.
- [x] The setting controls both hostile and passive natural spawning only in the owner's Pocket Base.
- [x] The command is unavailable until Pocket Base I is unlocked.
- [x] The command and its modes are offered through contextual autocomplete.
- [x] `/basesettings status` displays the current Pocket Base mob-spawning setting.
- [x] The preference persists across restarts and is reapplied when the Pocket Base world loads.
- [x] Disabling natural spawning does not remove existing mobs or prevent explicitly spawned or summoned mobs.
- [x] Persistence or world-application failures produce a clear failure message without reporting a successful change.
