Experiments.
Every question the project has put to a room, and what came back. Each card names the capture sessions or simulation runs it rests on, and the archive checks that claim, so a result here is backed by named recordings and never by prose alone.

Simulation campaigns 57 briefs · the machinery the simulation experiments ran on
A campaign is one supervised sweep of simulations against a brief. Sessions are sealed and carry their own synthesis and their own adversarial criticism. The run archive holds every run they produced.
