I may need to take a second look at Pi again if it has any niceties like that notable boost in round trip performance compared to hax.

I mostly stuck around with Hax because of a few design choices. The sessions are merely plain text files indexed by a dirpath slug. This means I can just start a hax session in that directory and expect sessions history to be available in any model.. (I occasionally dabble in GLM for security checks, Gemini for writing stuff, Deepseek for tightly scoped tests etc).
