One of the complexities in mid game is actually that you have too much Silt and need to get rid of it, but I also get that some players will see the possibility of running out and worry about soft-locking or feel that they can't shift workers away from the Depth Gauge task because they'll run out of Silt.
A small spoiler: Near the bottom, you gain an unlimited source of Silt so you can't soft-lock, but you do have to keep diving to reach it.

Yeah, it's actually not that bad. It would be nice if there was a tab where I could re-read the narration from previous veils. Also, what happens when Dread fills up?
The "when won" field on assaults doesn't like it when i increase the text size.
I think the names of the first two story achievements might be switched.
I think I got +60 max Mettle from somewhere and I'm not sure where.
There are many QOL improvements you could make to the binding system. A button to assign multiple, as another commenter said, but you could also add a function to save and load assignments, or at least a button to unbind all oneiri, everywhere.
You should make the price of units disappear when they're maxed out, the same way as constructs. Similarly, repeatable visions should disappear when they can't be poured any more.
