Fork the state into several possible futures, cheaply. Each one carries how likely it is, what must stay true for it to hold, and when it stops mattering. As evidence arrives the rest drop away, and the survivor becomes the real state in one step.

Agents have started trying things before they commit. A coding agent sketches three plans for a refactor and keeps the one whose tests pass. A travel agent holds a train, …

Multivergence 0.1 is out, open source under the Apache License 2.0. It’s a state engine for software that keeps several possible futures open at once: fork the …

A state engine for branching futures makes a handful of promises. A write to one branch never shows up in another. A promote happens completely or not at all, even if the …

The name is two halves of an idea. Divergence is the moment one state becomes several: an agent forks three plans and each goes its own way. Convergence is the moment …

A bug report comes in: Median([1 2 3 4]) returns 3, and it should return 2.5. A coding agent can usually think of more than one fix. The usual move is to pick the one it …

At 14:02 an alert fires: checkout’s p99 latency is 4.8 seconds, against a normal 300 ms. Whoever is on call, a person or an agent, starts with a handful of …

Booking a venue for a team offsite is a waiting game. You ask a few places to hold the dates, and each hold runs out at a different time. Quotes come back over the …

If your agents explore several plans, bookings or tool sequences before choosing, the project would like to hear what they branch on and what settles it.
