 ## Acceptance criteria
 
-- [ ] Base II requires Base I and an established base.
-- [ ] Base II unlocks at a configurable cumulative grass-or-dirt threshold that defaults to 500 blocks, 250 more than Base I.
-- [ ] Base II provides particle-based navigation and does not grant or require a physical compass item.
-- [ ] While enabled and in the base's world, particles are drawn along the ground to indicate the direction toward the base.
-- [ ] Particle generation is bounded to avoid excessive server or client load.
-- [ ] A player in another world receives a clear message instead of a misleading particle direction.
-- [ ] `/basenavigation` toggles guidance on and off after Base II is unlocked.
-- [ ] The navigation preference persists across reconnects and restarts.
