As people spent time in them, the oxygen would run out and be replaced with carbon dioxide, which is heavier than air and would sink to the bottom. With no exits and no airflow, wouldn't this become a straightforward deathtrap at some point? Or were there ways to force clean air to the bottom, somehow forcing out the CO2?

For that matter—A place to stash the kids from the census-taker and the harvest from the tax man? Tuck them away, just for that day, once every so often, and pull them out afterward?
Or knowledge privileged to some specific order, whose representatives are geographically widespread but sparse within a given community?

There's zero reason to expect remnants of food, as well. It was not shelf(tunnel)-stable.
There would still be signs. The food rots - but it would leave traces.
If you are hiding your family from almost certain death, 24 hours with no food or water in a cool dark cave is a possibility.

Seems to me that a secure hiding place that only works for up to N hours then becomes a death trap is a really bad concept
