A field does not make a project valuable. Its question, method and consequences do.
How we think about focus.
The areas below are a map, not a checklist. Work may move between disciplines, combine physical and digital systems or create a new category entirely.
Across every field, XTF looks for a clear problem context, a credible method, responsible testing, honest limits and a reason the work should exist beyond its maker.
The examples describe possible questions, not confirmed program themes or automatic eligibility. Every active program publishes its own scope and terms.
