Analytical Estate Topology
The full picture of where analytical data lands, is transformed and is served, including the paths that bypass the intended one.
Most organisations have one intended data path and several real ones. The intended path runs source to raw to modelled to serving. The real ones include a report built directly against a production replica, a finance spreadsheet fed by a scheduled email, a team's own warehouse bought on a departmental card, and an application reading a table it was never granted.
The topology is the map of all of them. Drawing only the intended path produces a diagram that is architecturally clean and predicts nothing about why two dashboards disagree.
The practical value is in the bypasses. Each one is either a legitimate requirement the platform does not serve — in which case it belongs on the roadmap — or an inherited shortcut that is now a dependency nobody owns. Both need naming. The characteristic discovery is that the spreadsheet nobody has heard of feeds a regulatory return, which makes it the most critical data flow in the estate and the only one with no monitoring.
