This is cool! I assume a lot of this was Fable orchestrating sub-agents with cheaper models, right? Something I noticed with Fable is that if it spun off three sub-agents in the cloud version of claude code, and then hit the 5-hour usage limit, all the work of those sub-agents would be lost (!). Did you run into the same thing?

One time though, I hit the limit when not running a sub-agent, and the agent resumed after the limit expired. Weird.

No this was all running on Fable. Used like 93% of my Max plan over the course of 2 days to get the initial version running
