## Overview

ParkRefund helps drivers challenge Danish parking fines: the customer enters or photographs a ticket, reviews an assessment and evidence guidance, gets an appeal draft, and submits the case for human review. The Streamlit app and iOS client share a Python API and claim-intelligence layer; the assessor is grounded by a rules module, while photo evidence receives a separate vision check. The README also describes an operations queue and dashboard. Source excerpts show most customer-flow calls; links to the unsampled dashboard internals are omitted where their wiring is not evidenced.

Main entry points: [`ios/ParkRefund/ContentView.swift`](https://github.com/milo-dotcom/claude-impact-lab-cph/blob/main/ios/ParkRefund/ContentView.swift) (Screen navigation), [`claims.py`](https://github.com/milo-dotcom/claude-impact-lab-cph/blob/main/claims.py) (Ticket and claim services), [`ios/ParkRefund/API.swift`](https://github.com/milo-dotcom/claude-impact-lab-cph/blob/main/ios/ParkRefund/API.swift) (iOS API client), [`api.py`](https://github.com/milo-dotcom/claude-impact-lab-cph/blob/main/api.py) (HTTP API and admin queue)
