-### Architecture: Dependency Injection
-
-REST API clients (Compute, Jobs, etc.) support two constructors:
-
-1. **Production**: `Compute(AuthConfig)` - Creates real HttpClient
-2. **Testing**: `Compute(std::shared_ptr<IHttpClient>)` - Accepts mock
-
-This pattern enables:
-- ✅ Fast, deterministic unit tests
-- ✅ Testing without external dependencies
-- ✅ Easy error scenario simulation
-- ✅ Request/response verification
-
 ### Available Assertions
 
 - `EXPECT_TRUE(condition)` / `EXPECT_FALSE(condition)`
