CAERIUS008 — DTO source emission failed

Severity: Error Applies to: [GenerateDto]

This is the DTO generator's final containment boundary. It stops source emission before an unforeseen generator defect can surface as CS8785, so no partial mapper is produced. Correct any preceding diagnostic first. If the input is valid and the error persists, report a CaeriusNet bug with a minimal declaration and the SDK/Roslyn versions.
