Trooper started as a fallback proxy for agents. Claude hits a quota, falls back to Ollama, session continues. No crashes, no lost context.
The interesting problem that came up wasn't model routing. It was context preservation.
When you're debugging something hard, you build up context over many turns. The problem statement, what you've tried, what failed. When you switch from a local model to Claude, all of that context has to go with it. And when you come back to local, the local model needs to know what Claude said.
That's what 4.0 solves.
How it works
