Question

Why must a file be declared again under outputFiles for it to be visible or downloadable in Kestra?

Answer

Kestra isolates task execution contexts. Files are only persisted and made available to subsequent tasks or the UI when explicitly declared under outputFiles. Without this declaration, files may exist temporarily during execution but are not surfaced or retained for inspection.
