Remarks

Not all properties are applicable for every BlockAction. For example, PreviousBlock may be null for insertions. Parent references may be null for root-level blocks.

var data = new BlockData
{
    Block = new BlockModel { ID = "b-200", BlockType = BlockType.Paragraph },
    PreviousBlock = null, // Not relevant for a pure move without content change
    CurrentParent = new BlockModel { ID = "parent-new", BlockType = BlockType.Template },
    PreviousParent = new BlockModel { ID = "parent-old", BlockType = BlockType.Template }
};
