 ## Acceptance criteria
 
-- [ ] Base-size progression is unavailable until Base I is unlocked.
-- [ ] Only qualifying blocks broken in Survival mode count.
-- [ ] The first expansion requires a configurable 500 `STONE` and changes the radius from 10 to 25 blocks by default.
-- [ ] After the stone tier, the second expansion requires a separate configurable 1,000 `DEEPSLATE` and changes the radius from 25 to 75 blocks by default.
-- [ ] After the deepslate tier, the third expansion requires a separate configurable 1,000 `OBSIDIAN` and changes the radius from 75 to 150 blocks by default.
-- [ ] Stone, deepslate, and obsidian variants do not count by default.
-- [ ] Materials mined before their sequential tier becomes active do not count toward that later tier.
-- [ ] Player-placed qualifying blocks may be mined repeatedly for progress.
-- [ ] Expansions affect the cylinder's horizontal radius without independently changing its vertical bounds.
-- [ ] Relocating the base preserves earned size tiers and counters.
