CAERIUS006 — Generator target shape is not supported

Severity: Error Category: CaeriusNet.Analyzer

Cause

A generator target is generic/nested or has a shape that CaeriusNet cannot generate safely. Targets must be non-generic top-level partial types. [GenerateDto] is a sealed reference type; [GenerateTvp] is either a sealed positional record class or a readonly positional record struct. An ordinary class with a primary constructor is not a TVP target.

Why

The source generators emit companion partial declarations that must be placed in a well-known namespace without additional type parameters. Generic and nested types would require reproducing the enclosing type hierarchy and all type parameters in the generated output, which is not currently supported.

How to fix

Move the type to the top level and remove any generic type parameters. Use a sealed positional record class or readonly positional record struct for a TVP.
