Have we verified these results on a streaming data computing engine(eg. Flink)?

I haven't run them, but the Flink playground https://kafka-options-explorer.conduktor.io/flink-sql accepts these queries, which used to crash.
I think the data is small enough that they can be validated manually. I don't have access to a Flink installation.

Changes Proposed
If the session key is not supplied, use the
nullvalue at runtime instead, placing all rows in a single timeline.
