Identified Risks are not listed as an input to the Create User Stories process in the SBOK process model corresponding to this question.
The legacy SBOK Create User Stories inputs include the Scrum Core Team, Prioritized Product Backlog, Done Criteria, Personas, stakeholders, Epics, Business Requirements, applicable laws and contracts, and Scrum Guidance Body recommendations. The newer SBOK structure similarly retains the Prioritized Product Backlog, Done Criteria, Personas, and related requirement inputs.
The Prioritized Product Backlog provides the prioritized requirements from which detailed User Stories are elaborated. Personas help the Product Owner frame requirements from the perspective of representative users. Done Criteria establish common completion requirements applicable across User Stories.
Identified Risks certainly affect Scrum planning and backlog prioritization and are inputs to several other processes, but they are not formally included in the Create User Stories input list for the edition represented by this question.
Therefore, Identified Risks is the exception.
