## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `renderer` names no product |
| 2. A precedent | pass: [Unity SystemInfo](https://docs.unity3d.com/ScriptReference/SystemInfo.html) (row `K65`); [WebGLRenderingContext.getParameter](https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/getParameter) (row `K65`) |
| 3. Two apps, or labs | pass: 7 apps (ledger: app-0c773a4ee3, app-b362a81c85, app-b4ae2fce25, app-ddfb017681; fleet cross-check: app-b362a81c85, app-f9a32142f1, app-fc07850558, app-fd09090420) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `K65` at tier stable (a member only where no rule, data, asset or app code serves the need) |
