Infinite bottle raid farm

Auto raid farm that makes its own ominous bottles, so it never has to stop. A fake village and a bubble column switcher move you in and out of position, the game drinks the bottle for you, and an autoclicker with a sweeping edge sword kills the raiders while a beacon keeps you standing. The loop is the clever part: kill the captains with your inventory full, the banners stay on the ground, the banners make new captains, and the captains drop more bottles. Java, 1.21.2 and up. It is the only raid farm here that needs no bottle supply at all, and the only one where the gear is the real cost rather than the blocks.

Full enchanted diamond or netherite armour with Protection IV, and a sword with Sharpness V, Sweeping Edge III and Mending. Iron swords break before the raid ends and unenchanted diamond armour will not stop the vexes.
Do not wear an elytra while running it. You need the chestplate on to survive the damage.
If the bottles are not replenishing, fill your inventory so you cannot pick up the ominous banners. Banners left on the ground are what create new captains, and the captains are what drop the bottles.
Raids that keep failing mean land within 8 chunks of the farm, or difficulty below hard.
Never put knockback or fire aspect on the sword. It changes how fast the armor stand falls down the hole, and the whole timing hangs on that.
The schematic has one piece of redstone wrong. By the piston at 15:10 it has to be a dot, not a cross, and the creator says so in the description himself.
