 ## Acceptance criteria
 
-- [ ] Flight progression is unavailable until Base I is unlocked and a base is established.
-- [ ] The plugin observes elytra held directly in the player's inventory and armor equipment while the player is in Survival mode.
-- [ ] Elytra inside shulker boxes, bundles, or other nested containers do not count.
-- [ ] Observing one elytra permanently unlocks Flight I, two simultaneous elytra unlock Flight II, and three simultaneous elytra unlock Flight III.
-- [ ] A player observed with enough elytra for a later tier receives all unmet preceding flight tiers.
-- [ ] Elytra are not consumed, and losing them later does not revoke an earned tier.
-- [ ] Flight I permits plugin-granted flight within the current horizontal base radius and from 25 blocks below through 25 blocks above base Y by default.
-- [ ] Flight II expands the vertical range to 100 blocks below and above base Y by default.
-- [ ] Flight III expands the vertical range to the world's minimum and maximum build heights.
-- [ ] A configurable five-block horizontal warning buffer extends beyond the current base radius.
-- [ ] Plugin-granted flight remains active in the warning buffer and displays prominent on-screen notice that the player is leaving the base.
-- [ ] Passing beyond the warning buffer removes only flight granted by this plugin.
-- [ ] Flight is not granted outside the unlocked vertical range.
-- [ ] `/baseflight` toggles the player's unlocked base flight on and off.
-- [ ] The flight toggle persists across reconnects and restarts.
-- [ ] The plugin handles teleportation, world changes, game-mode changes, death, logout, and plugin shutdown without leaving unintended flight enabled.
