How this lab works
Gemini 3.5 Flash-Lite interprets your question and selects up to two authored statements. The server checks those IDs and displays the original case text. It does not display freely generated witness facts. Records unlock through questioning; feedback follows fixed evidence rules and cites your questions.
This is a constrained simulation, not a general conversation or a validated assessment. Questions are sent to Google to select a response. This app holds your case in server memory for up to 30 minutes; it does not save a permanent transcript. Restarting the server clears sessions. Avoid entering personal information.
