-and added the one signal it was missing
Track 01 — AI & Agent Observability. A hackathon project built from scratch, July 20–26, 2026.
There's a sentence we said to each other on day one and then kept saying all week, because it kept being true:
An API 200 is not evidence that a feature works.
This post is the story of a project that lives entirely inside that sentence. It's about a feature SigNoz already shipped that almost nobody can reach, a real bug that makes part of it impossible, and a missing signal — measured answer quality — that we built on top. And it's about how we used SigNoz not as a black box but as the thing under test.
