Code/V2/Domain/Items.cs
Domain record types for items and world-placed items. ItemRecord stores an item id, definition id, a dictionary of trait payloads and a revision, with a DeepCopy method that clones the traits. WorldTransformRecord holds position and rotation components. WorldItemRecord links an ItemId to a transform and revision.
