"""Compare block entity data on items with vanilla 26.3.

The Java oracle (VanillaPickBlockDataOracle) loads each block entity with
BlockEntity.loadStatic and runs ServerGamePacketListenerImpl.addBlockDataToItem
(Ctrl + Pick Block in creative) on the block's item, then places an item as a
block entity: BlockItem.updateCustomBlockEntityTag (op-only types only for a
game master) and BlockEntity.applyComponentsFromItemStack. The Rust example
(pick_block_data_fixture) runs horizon_client::block_entity_item on the
canonical saved NBT. The picked component patch and the placed block entity's
saveWithFullMetadata are compared for every block entity type that carries data:
containers with items, names, locks and loot tables, signs, banners, command
blocks, spawners, trial spawners, vaults, beehives, pots, skulls, lecterns and
more, picked and placed back, with hand-written patches (data of another type,
op-only data without permission, merges into a filled block entity, leftover
components).
