-  - The risk assessment is generated from workshop 4, thanks to a dedicated button. When the risk assessment is generated again, automatic versioning is applied, and mitigations can be copied on demand (based on ref_id of operational scenarios). 
   - After generation, a risk assessment is fully editable, to allow customisation, and the risk assessment can be managed normally as any other risk assessment.
   - risk treatment is based on the risk assessment.
