# V2 Cook Validation

`V2/ue/Build/Cooking/v2-cook-validation.json` defines the validation step that
runs after parallel cooking and before cooked artifacts are published. It
verifies that cooked assets load correctly and that cooked package references
resolve through the dependency graph.

`plan-v2-cook-validation.py` emits one `V2CookValidationCommandlet` load check
per platform profile and validation asset. The command receives the cooked
package path, platform asset registry, dependency graph, and per-asset report
path.

The validation suites cover texture, shader, material, mesh, audio, animation,
and level-world packages. Material and level suites also check missing
references against the expected dependency graph edges. Asset registry coverage
must remain at 100 percent for the validation fixture.

The `missing references` report is the publishing blocker for this validation
step.

Required gates:

- `cook-validation-plan-generated`
- `cook-validation-load-success`
- `cook-validation-missing-references`
- `cook-validation-suite-coverage`
- `cook-validation-command-coverage`

The primary failure metric is `cook.validation.missing_reference_count`. The CI
validator is:

```bash
python3 V2/ue/Tools/check-v2-cook-validation.py
```
