[CarlyCotton]

Acceptance Criteria

• Upgrade Camunda to 8.8
  • Dev/Test (Nov 2025)
  • Stg/Prod
• Update client process_definition permissions with the client id as the 'owner':

Automatic permissions on upgrade for the client do NOT include update_process_instance which causes any assessment cancellations to fail. When these fail the assessment records remain in 'Cancellation queued'.
