Conceptual Foundation

For full architecture context, see FOSMVVMArchitecture.md | OpenClaw reference

ViewModel testing in FOSMVVM verifies three critical aspects:

1. Codable round-trip - ViewModel encodes and decodes without data loss
2. Versioning stability - Structure hasn't changed unexpectedly
3. Multi-locale translations - All @LocalizedString properties have values in all supported locales

The LocalizableTestCase protocol provides infrastructure that tests all three in a single call.
