Help me apply Gherkin to the material below.
Reader and existing knowledge: [describe]
Task and desired outcome: [describe]
Use these principles: Use Given for relevant starting context.; Use When for the event under examination.; Use Then for an observable outcome; keep incidental interface details out unless they matter..
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.
