Dear Judges, I'm writing with a brief update regarding my submission, Sentinel. After the contest period, the Google Cloud credits I relied on to host the project were exhausted and the billing account was closed, which took the original Cloud Run deployment offline. Rather than let the project go dark, I re-deployed it myself so it remains fully accessible to you.

I want to be honest about who built this and how. I'm a student in Uganda, working alone, with no funding and no team. When the cloud credits ran out, I didn't have the money to simply keep paying for infrastructure , so instead of giving up, I re-engineered the deployment to run without that billing dependency. The AI layer now authenticates to Google's Gemini models through the Gemini API rather than Vertex AI service credentials, but it still runs on Gemini 3.5 Flash, and the original Google Cloud architecture (Vertex AI, Agent Builder, Cloud Scheduler) remains intact in the codebase exactly as built and submitted. No functionality was removed . I only changed the hosting path so the project could survive losing its credits.
I didn't build Sentinel for a prize. I built it because of a real problem in my own community. Most outbreak systems monitor patients . Sentinel monitors whether the monitoring system itself is silently failing, and autonomously works to repair the coverage gaps before people fall through them. I researched, designed, and implemented every part of it myself, learning what I needed as I went, because I believe this idea matters.
I'd be grateful to have it evaluated on its technical merit, creativity, architecture, and vision, and I'm happy to provide any additional documentation, recordings, or codebase access that would help. Thank you for your time and your consideration and for creating a space where a student with an idea and no resources can still try to build something that matters.
Sincerely, Nestroy Musoke Sentinel — Developer
