## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `parent` names no product |
| 2. A precedent | pass (through its owner [`Part`](Part.md)): [DOM Document.getElementById](https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementById) (row `G31`) |
| 3. Two apps, or labs | pass: 28 apps (ledger: app-04c2774145, app-b362a81c85, app-c1384707fc, app-f9a32142f1, app-fc306ec3dc; fleet cross-check: app-04c2774145, app-0c773a4ee3, app-37356bf09f, app-378d190f1b, app-4762caacdc, app-4f16d2f6da, app-4fd23bc869, app-510d750508 and 20 more) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `G31` (through its owner [`Part`](Part.md)) at tier stable (a member only where no rule, data, asset or app code serves the need) |
