Definition
Child of [Metrics Stack]. Provisional, 05.10.2026. Road 2-side application of the parent [Metrics Stack] — the set of measurements that track relational build rather than transactional extraction.
Explanation
Where the base [Metrics Stack] can run either direction depending on what an operator chooses to track, [Relational Metrics Stack] names the specific Road 2 version: the instruments that surface loyalty, return frequency, referral, and accumulated Guest-graph density rather than the dashboard numbers that dominate Road 1 reporting. This pairs with the broader upstream and downstream frame in the [Read] discipline — most of what this stack measures lags the way profit metrics lag, which is exactly why an operator has to build the discipline to track it deliberately rather than waiting for it to show up on a standard P&L.
