The idea

Source Evidence Card explores a simple question: can a small document lookup stay useful while making its evidence and limits easy to inspect? It is intended for readers checking procedural information in one selected public Chinese health-insurance guide. This is an exploratory prototype, not a validated personal pain point or a medical-benefits decision service.

What it does

Enter an English or Chinese question. The app checks the downloaded source and returns an original passage with its section, publisher, publication date and official link. It preserves conditions when a procedure applies only in some circumstances. If the guide cannot establish a claim, such as a personal reimbursement percentage, it reports insufficient evidence. Two demonstrated passages include clearly marked, unofficial AI English translations.

How it was built

An AI coding agent prepared draft scope, product requirements, a technical specification and a build checklist, then implemented a Python standard-library server and a buildless HTML, CSS and JavaScript interface. The project uses the pinned Devpost Learn Skill Pack. Independent AI review found boundary, cache-validation and request-state issues that were corrected. The current implementation passed 40 automated checks, a fresh-copy run and desktop/mobile browser checks. These are development checks, not a user study or an accuracy benchmark.

The main challenge

A related passage is not necessarily evidence for a conclusion. The prototype uses inspectable procedural rules and conservative abstention, with limited topic coverage rather than unrestricted policy answers.

Authorship and current limits

This submission draft and the implementation were prepared with AI assistance at the participant's request. Participant plan review, hands-on validation and personal learning reflections are not established by automated checks. The project makes no claim that AI activity proves participant learning or real-world effectiveness.
