| 2. A precedent | pass: [Onshape mate connectors](https://cad.onshape.com/help/Content/mate_connector.htm) (row `K63`) |
| 3. Two apps, or labs | pass: 14 apps (ledger: app-04c2774145, app-37356bf09f, app-4762caacdc, app-c1384707fc, app-f9a32142f1; fleet cross-check: app-04c2774145, app-37356bf09f, app-4762caacdc, app-510d750508, app-b362a81c85, app-bcb7ef21da, app-c1384707fc, app-ceb4eccc72 and 6 more) |
