Even today the LEGO-compatible knock-offs are complete junk, my kids occasionally end up picking up a loose bag for £1 from the local charity shop. Pieces don't stick together properly (with each other, let alone LEGO pieces); legs, arms, and hands come off the minifigs; etc. You can instantly tell — even ignoring the assault rifles that would never make it in a LEGO box.

Good questions

> Are the raw files in the working repository GeoPackages?

The working copy for a vector/table dataset can be in a GeoPackage or a SQL database like PostGIS. For rasters/point-clouds they're flat files.

> How is it tracking the changes made inside the geopackages?

In general, triggers which store RowIDs/PKs of inserts/updates/deletes. Then when you ask for a diff or make a commit Kart figures out any actual row-level (or schema) differences.

> What happens if it's replaced with an updated copy of the geopackage the was edited via some other application?

If it's edited by something else (QGIS, ArcGIS, python/go/whatever application, SQL CLI, whatever) it'll work: you do edits where you want to. If it's replaced by something else, it won't work.

> How does it diff the changes?

Comparing the features/rows in the repository (and their schemas) against the rows in the working copy database. It uses the stored list of modified rowids to make this fast.

The BluMartin FreshAir 100 and the Fresh-R series are both MVHR units that fit into existing walls: there’s a Fresh-R model that goes into a window frame too.

Different brands vary, but IME this is only correct for a few weeks at best. Otherwise you'll get a lot of residue, and if it's been outside exposed to UV you'll get even more. And duck tape is worse.
