The general context / expected result columns are way more useful than the exact files/functions we are calling but get cutoff when viewing the page. I'd move those left so people can read them easily. TBH the file/function might not even be worth it if it doesn't really fit on the page. |

This is nit, but every time I see this, I read it as relating to the instructor dashboard reset feature, not the instructor service. This makes me read "Instructor Mark Subsection Completed the same way, even though it has nothing to do with the instructor dashboard. Do you think we need to keep "instructor" in these names, since the other downstream effects don't contain the related service names? I think it makes it confusing. |

Event Triggers: | ||||||

We will define the events in edx-exams such that they are emitted whenever an exam attempt is submitted, rejected, verified, errored, or reset. | ||||||
After these events are emitted, they will trigger their respective chosen downstream effects. | ||||||

I'm having a hard time understanding this sentence. I've read it three times and am still struggling. Maybe it's because it's Friday afternoon.
Are you trying to say something like this?
"Below are lists of expected downstream effects of exam submission and review. We have decided to implement some downstream effects and not others; these decisions are enumerated below. Those that will be implemented will be triggered by events emitted by the
edx-exams
service, as described in this decision."
