Rule Result
1. Neutral name pass: open names no product
2. A precedent pass (through its owner HistoryGroup): Unity Undo.CollapseUndoOperations (row X7)
3. Two apps, or labs pass: 6 apps (ledger: app-04c2774145, app-37356bf09f, app-4762caacdc, app-bcb7ef21da, app-f3598fad77; fleet cross-check: app-04c2774145, app-37356bf09f, app-4762caacdc, app-510d750508, app-bcb7ef21da, app-f3598fad77)
4. The cheaper fix first decided per need in Appendix B: rows X7 (through its owner HistoryGroup) at tier stable (a member only where no rule, data, asset or app code serves the need)
