Deterministic worlds · real agents · one causal timeline
Declare a deterministic world around a real Spawnfile organization of AI agents, run it, then replay one causal timeline to see what happened, and why.

01 / World
A single Simfile declares the clock, variables, generators, rules, markers, and falsifiable probes around your agents. The mechanics are deterministic for a seed; the agents still decide what to say, remember, and do. The world can wake an agent or post into a room; it never scripts a thought.

Drag one cursor. The world map, the room conversation, every agent's memory, and the causal traces all return to the same moment. A sealed run with participant speech opens on Conversation; Map remains one click away. Every glyph points to a record. Ask anything which records make it true. The header always discloses whether the dialogue came from a real engine or a scripted fixture.

Descend into an agent
An agent can itself be an organization. In the Jungian run, a Shadow and an Anima deliberate in a private room while the representative synthesizes the one answer the outer world hears, and the same viewer follows both levels.
