Hi all, So after some discussions on the previous draft for restartable tasks and considering other feature requests such as to allow frameworks to customize the behavior when tasks in a task group terminate, we incorporated these features into one OnTerminationPolicy concept, which governs the executor's handling of task termination and the agent's handling of executor termination.
Here is new doc: https://docs.google.com/document/d/1VxfoZ-DzMHnKY0gzoccHEhx1rvdC2-RATJfJUfiAwGY/edit?usp=sharing Feedback welcome!
