Diagnostic rules
CaeriusNet analyzers validate [GenerateDto], [GenerateTvp], and AutoContracts manifest inputs at compile time. Diagnostics are emitted by the analyzer included with the CaeriusNet package and appear in IDE builds and dotnet build.
Use these pages as the rule reference for generated DTO, TVP mapper, and AutoContracts manifest issues.

Build policy
Keep error diagnostics fixed in source. Treat warning suppressions as design decisions and prefer documenting them near the affected type or AutoContracts manifest entry.
See also the higher-level Compiler Diagnostics guide for suppression and severity configuration.
