Investigation replay

Watch the agents argue, and the bytes settle it.

Each of these is a real run, exported straight from LastCopy. Step through the World Model’s plan to see suspicions become hypotheses, the Reviewer push back, raw evidence overturn a guess, and the gate clear every tablet.

The coordinator asks
