Working notes from the edges of Changeist's practice — tools, simulations, frameworks, and experiments that don't always reach a deliverable but shape how we think. Each piece shows something we built, the decision that shaped it, and one honest observation from making it. Published irregularly, when something is worth showing.

Simulating Mobility Futures
Making future transportation tradeoffs feel like lived decisions, not policy abstractions.
