| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `shadows` names no product |
| 2. A precedent | pass: [Unity Light.shadows](https://docs.unity3d.com/ScriptReference/Light-shadows.html) (row `K27`); [Babylon.js ShadowGenerator](https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Lights/Shadows/shadowGenerator.ts) (row `K27`); [Unity Renderer.shadowCastingMode](https://docs.unity3d.com/ScriptReference/Renderer-shadowCastingMode.html) (row `K34`); [Unity Renderer.receiveShadows](https://docs.unity3d.com/ScriptReference/Renderer-receiveShadows.html) (row `K60`) |
| 3. Two apps, or labs | pass: 10 apps (ledger: app-0c773a4ee3, app-378d190f1b, app-4f16d2f6da, app-510d750508, app-59c5b5751e, app-b362a81c85, app-ceb4eccc72, app-fc07850558 and 2 more) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `K27`, `K34`, `K60` at tier stable (a member only where no rule, data, asset or app code serves the need) |
