Your agent demo is rigged (mine was too), so I let the judges write the tests

Built for the All Things Agentic Hackathon. The project: an autonomous

compliance agent for cannabis track-and-trace, running on Cloud Run with

Gemini 3.5 Flash. This post is about the test harness, because it turned out to be the most interesting part.

The objection every agent demo deserves

Every hackathon agent demo has the same silent flaw: the person who built the agent also built the test. Of course the agent passes. The demo world was constructed, consciously or not, around what the agent is good at.
