iamspyder/black-veil ? reverse-engineered prompt

Build me a Streamlit game called BLACK VEIL where I play as the human examiner at a door and I can question eight different AI people one at a time. One of them should secretly be a mole, and I need to figure out who it is before I let too many people in. Each agent should have a distinct personality, a public identity, some private secrets, and a bit of memory so they stay consistent or slip up if I push them.

I want the interface to feel like a tense vault door scene, with a live feed of each exchange, buttons to let in, turn away, or hold an agent, and a clear win or lose state. If an API key is missing, make it still run with a simple fallback so the game does not break. Keep the answers short, natural, and easy to read. Use the current docs online if you need to.
