At the price per student it probably makes sense to run some voluntary trial exams during the semester. This would give students a chance to get acquainted to the format, help them check their understanding and if the voice is very intimidating allow them to get used to that as well.
As an aside, I'm surprised oral exams aren't possible at 36 students. I feel like I've taken plenty of courses with more participants and oral exams. But the break even point is probably very different from country to country.
The solution of differential equations by separation of variables in physics is also notated in an abusive way. You have some differential equation
dy/dx = g(x)h(y)
You separate the variables by some quick manipulations
dy/h(y) = g(x) dx
And then you have a small step in some coordinate on both sides. So by integrating both sides
\int 1/h(y) dy = \int g(x) dx
you find a solution to your differential equation. Obviously there's a real formal procedure underneath it with also some safeguards. For example you're supposed to check that h(y) doesn't equal 0 at any point. But the happy path in physics is often done without worrying about all that.
Anubis is not meant to stop single endpoints from scraping. It's meant to make it harder for massive AI scrapers. The problematic ones evade rate limiting by using many different ip addresses, and make scraping cheaper on themselves by running headless. Anubis is specifically built to make that kind of scraping harder as i understand it.
I think that's an overly uncharitable read on this approach. Lots of tasks that have difficult thoughts, that need to be thought before they can be completed, also have phases in which work just has to be done. I'm in the middle of collaborating on an article for submission to a physics journal. I wouldn't term it filler work, but most of the complex thoughts on the problem have been thought through and the work right now is creating a coherent story that goes over our results. An outline method would work fine for this part of the project.
As for the spy novel, i think the outlining is actually quite similar to how Sylvester Stallone described his writing process[0]. You wouldn't fill the outline with generic beats, you would put in your basic plan for the story.
I think the most I experienced at the physics department in Aarhus was 70ish students. 200 sounds like a big undertaking.
