I built a build verification system in 1 month using only Android and AI

For the past month, I’ve been working on a small personal project to understand software integrity and verification better.

My goal was to build a simple system that can verify whether a commit or build output was modified.

I didn’t use a computer for this project.
Everything was done on an Android phone, with AI as a coding assistant.

The system I built (BuildSeal) works like this:

• Generates a seal for a commit or content hash
• Allows verification using a seal ID
• Returns results like: Genuine / Modified / Not found
• Includes a local verify tool for independent checking

This project was mainly for learning.
Feedback is welcome.
