At Chile’s Vera Rubin Observatory, Earth’s Largest Camera Surveys the Sky

I'm looking for more sources of information about how the data is scrubbed of NRO satellite data.

Scott Manley mentioned in his recent video that archived data is not scrubbed, but the alerting pipeline is. I would think that artificial satellites were already scrubbed, but I suppose the National Reconnoissance Office and Department of Defense could their own filter.

Archived raw data probably contains everything

The software pipelines are open source and public (I think?), so maybe you could look at the code?
