## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `format` names no product |
| 2. A precedent | pass: [Babylon.js GLTF2Export](https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/serializers/src/glTF/2.0/glTFSerializer.ts) (row `K39`); [USDZ file format](https://openusd.org/release/spec_usdz.html) (row `K39`) |
| 3. Two apps, or labs | pass: 11 apps (ledger: app-4f16d2f6da, app-510d750508, app-bcb7ef21da, app-ceb4eccc72, app-f07e9033d9, app-fb16dd1985, app-fc07850558, app-fc306ec3dc and 1 more; fleet cross-check: app-4f16d2f6da, app-510d750508, app-59c5b5751e, app-ceb4eccc72, app-e61a0b42ad, app-f07e9033d9, app-fb16dd1985, app-fc07850558) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `K39` at tier stable (a member only where no rule, data, asset or app code serves the need) |
