Constant miden_objects::notes::NOTE_LEAF_DEPTH

pub const NOTE_LEAF_DEPTH: u8 = _; // 21u8

The depth of the leafs in the note Merkle tree used to commit to notes produced in a block. This is equal NOTE_TREE_DEPTH + 1. In the kernel we do not authenticate leaf data directly but rather authenticate hash(left_leaf, right_leaf).
