Functional Requirements

• Prerequisite: Need to track donations (See Issue Contributor Tracking (Top Donors) #21/Events).
• Logic: Push or Pull refund. Pull is safer.

---

Suggested Implementation

// IN FUNCTION: claim_refund(env, request_id)

// 1. Load Request. Check status is 'Cancelled'.
// 2. Look up 'Donation(request_id, caller)' in storage.
// 3. If amount > 0, transfer amount back to caller.
// 4. Set Donation amount to 0.

Acceptance Criteria

• Only works if Cancelled.
