**Sizing**

* T-shirt size:

[ ] S
[ ] M
[ ] L
[ ] XL

(S=1-2 Sprints, M=2-3 Sprints, L=4-5 Sprints, XL=not sure, probably more than 5 Sprints).

* *Risks and Assumptions**

1. [ ] What are assumptions?
2. [ ] What are the risks?
3. [ ] Have we done an RFC on a technical approach?
4. [ ] Are the dependencies (technical, business, regulatory/policy) known?
5. [ ] Has work on this Epic been prioritized with key stakeholders?

No files, tests, entry points, technical approach, dependencies, or concrete notification requirements are identified. Start by clarifying which request-status updates and required actions need email notifications for each listed role, then define the prioritized scope and acceptance criteria before locating implementation work.
