Wealth is never in one place and never truly hidden. It sits across a small number of readable layers, and a map naming which layers apply to a given subject lets the reader ask the right question at each layer, rather than the same question everywhere.
A family office considering a fresh relationship with a principal whose visible profile spans four countries cannot answer the counterparty question by picking a single layer. The bank layer, the corporate holding layer, the real property layer, the moveable asset layer, the digital asset layer, the philanthropic layer, and the fiduciary layer each carry a different fraction of the picture, and asking the same question at each of them is how the office produces a thick file that answers nothing.
A working map is modest. A defined list of layers relevant to the subject. A named register or source class for each. An expected filing cadence for each source. A person or team accountable for the layer. A review interval. Where a subject has no exposure at a layer, the layer is marked as such rather than omitted, because the absence is itself a piece of information.
When a file is unusually thick without being unusually clear, redraw the map before doing more reading. The map restores the triage.
