  "message": "Adds CTS test coverage for the `snorm10-10-10-2` vertex format. (#4695)\n\n* This PR adds CTS test coverage for the `snorm10-10-10-2` vertex format.\n\n* Adds `snorm10-10-10-2` to `kVertexFormatInfo` in `capability_info.ts` (with an explicit cast until `@webgpu/types` is updated).\n* Adds signed 10-10-10-2 bit-packing (`makeRgb10a2Signed`) and normalization (`normalizeRgb10a2Signed`) test helpers.\n* Adds packed format test data in `correctness.spec.ts` to verify conversion from raw vertex data to `vec4\u003cf32\u003e` in the vertex shader.\n\nIssue: https://github.com/gpuweb/gpuweb/issues/6292\n\n\u003chr\u003e\n\n**Requirements for PR author:**\n\n- [x] All missing test coverage is tracked with \"TODO\" or `.unimplemented()`.\n- [x] New helpers are `/** documented */` and new helper files are found in `helper_index.txt`.\n- [x] Test behaves as expected in a WebGPU implementation. (If not passing, explain above.)\n- [x] Test have be tested with compatibility mode validation enabled and behave as expected. (If not passing, explain above.)\n\n**Requirements for [reviewer sign-off](https://github.com/gpuweb/cts/blob/main/docs/reviews.md):**\n\n- [ ] Tests are properly located.\n- [ ] [Test descriptions](https://github.com/gpuweb/cts/blob/main/docs/intro/plans.md) are accurate and complete.\n- [ ] Tests provide complete coverage (including validation control cases). **Missing coverage MUST be covered by TODOs.**\n- [ ] Tests avoid [over-parameterization](https://github.com/gpuweb/cts/blob/main/docs/organization.md#parameterization) (see case count report).\n\nWhen landing this PR, be sure to make any necessary issue status updates.\n\n* Roll @webgpu/types to 0.1.72\n\n* Address review comments on makeRgb10a2Signed\n\n---------\n\nCo-authored-by: Kai Ninomiya \u003ckainino@chromium.org\u003e",
