Blueprint Code Review

🔴 Block merge

• Nullable suppressed: ! operator used to silence a nullable warning — fix the root cause
• Logic in controller: business logic placed directly in a controller instead of an IRequestHandler<T> — move it to the handler
• API contract changed without regenerating the NSwag TypeScript client (npm run nswag)
• Secret / credential committed to code or config
• Build warning introduced — TreatWarningsAsErrors is on; CI will fail
• Generated Angular file edited manually — files under src/app/features/ produced by npm run codegen:run must never be edited by hand; update the CodeGeneration.Setup configuration instead
• NuGet version added to a .csproj — all versions must be declared in Directory.Packages.props only
