please check the scaladoc above, it needs to be adjusted

what should I add? will timeout be used for all "flatMap chunks" except first?

@tobiajo, I am not sure, probably not as the cause was fixed upstream in Cats-Effect. Though I tried to rebase - let's see, if it works. In current situation it is more about semantics instead of a bug. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Keep a deterministic assertion for per-thread isolation.
The removed assertions were the only checks that distinguished thread-local state from one shared value. The remaining checks can pass with a globally shared implementation. Use two dedicated single-thread execution contexts and assert that get returns different initial values on the two threads.
