The Good
Overall, I really like this. It's a unique anomaly and you tell an interesting narrative in a pretty standard format. The testing logs are great and give just the right amount of information to give us the idea of what's happening without turning into an exposition dump.
The Less Good
Firstly, I'd recommend making the image a bit smaller. I have 27" monitors and it takes up the entire screen. There are ways you can have the image start small and have the reader enlarge it - I'd recommend giving one of those a shot, because it's really kinda distracting.
Its chemical composition indicates a source of naturally-occurring precipitation, or rainwater.
I feel like "naturally-occurring precipitation" is understandable enough on its own.
but working towards the construction of a single, massive tower comprised of their combined, fallen dead.
"fallen dead" is superfluous.
is that these microorganisms propagate through liquid H20,
You can do a subscript number by putting two commas around it, like so: H,,2,,O becomes H2O. You also appear to have used a zero rather than the letter O.
The Completely Subjective
ABRIDGED TEST LOGS
You call them abridged but all the information seems really complete, and I don't see any major gaps in time.
Why do they need D-Class to depress the water droplet? Could they not create an automated hydraulic system that does it? Seems like an unnecessary risk. And what would be the consequence of these things reaching the microscope's lens anyway? Why is that something that must be avoided? They don't know they can control humans until much later in the testing logs, so why do they see that contamination as such a threat? Their denial to allow her to use a metal rod and this suggest the Foundation already knows this can happen, but if they do, nothing is ever really done with that.
