Interrogation Room
A deploy key left the server room at 02:14. Three people were in the building. You get eight questions and one accusation. The suspects can lie to you, but they cannot invent facts.
Start with where everyone says they were, then find the person whose story someone else contradicts.

How it works
The scenario generator runs first and writes a truth ledger: who was where, who saw whom, and who took the key. Every answer you get is a lookup against that ledger, filtered by what the speaker knows and bent by whether they have a reason to lie. Nothing is generated at answer time, so the case is always solvable and never contradicts itself — that is the truth firewall. This build phrases the answers with templates. The production version swaps the phrasing layer for a model call: it receives the permitted facts and the speaker's disposition and returns only the wording, so a hallucination cannot change what is true.
