The datapack contains draw-origin yaw/pitch capture, 8-way direction classification, release dispatch, damage functions, model-pose item modifiers, slash effects and guard functions.

DAI 1.9.9 currently exposes attack/use state to the human trace and item-model keybind conditions, but the current datapack reaction surface does not expose attack-release or continuous camera-delta callbacks. The included bridge package documents the small DAI client input/render hook required to call these functions and suppress the vanilla bob swing.
