Building the World Model

From autonomy architecture simulations to world.json — the session where the Enterprise Crew got a shared brain. Three pi-research runs. One canonical world model. The beginning of coherent multi-agent reasoning.

What happened here

After running autonomy architecture simulations (6 architectures, scored across context sharing, failure resilience, and cascade risk), Henry and Ada realized they were solving the wrong problem. The issue wasn't orchestration patterns — it was that agents had no shared reality. Each agent reasoned from isolated files. There was no single source of truth.

This session built that foundation: world.json, a propagation model, three parallel pi-research tracks to stress-test the design, and the first concrete answer to "how does a signal from Henry reach the right agents at the right time?"

Architecture E+D composite 8.85
p99 propagation latency 0.299h
Scale tested 50 agents

What we found

Track 1 — Propagation

Selective propagation (notify only subscribed agents) outperforms broadcast at scale. Dampening rules matter more than routing. An offline agent should buffer signals, not drop them.

Track 2 — Structure

Optimistic concurrency with field ownership is the right consistency model for concurrent agent writes. Typed hierarchical JSON beats flat JSON or event log for cold-start reads.

Track 3 — Synthesis

Architecture E (Intent Graph) inside a D (Orchestrator Loop) wrapper achieves >8.5 composite with controlled cascade risk. The world model must encode agent subscriptions, not just entity state.
