we implemented a similar idea some time back and it has proven quite useful: https://blog.codesolvent.com/2025/01/applying-forkjoin-model...

In Solvent, the main utility is allowing forked-off use of the same session without context pollution.

For instance a coding assistant session can be used to generate a checklist as a fork and then followed by the core task of writing code. This allows the human user to see the related flows (checklist gen,requirements gen,coding...etc) in chronological order without context pollution.
