Help me apply BPMN to the material below.
Reader and existing knowledge: [describe]
Task and desired outcome: [describe]
Use these principles: Distinguish activities from the events that start or interrupt them.; Label decision conditions and alternate paths.; Use participant boundaries consistently; messages between participants differ from sequence flow within a process..
Preserve source facts, identifiers, quantities, conditions, exceptions, and uncertainty.
Separate supplied facts from assumptions. Ask for missing information instead of inventing it.
Explain your representation choices and provide a review checklist. Do not claim formal compliance or correctness from formatting alone.
Material: [paste only information you are permitted to share]
