Classes still fully online. Getting used to it in a way I'm not sure is healthy — I've stopped minding as much as I probably should. Fewer distractions means more hours for the actual work, and I notice I'm not exactly mourning the campus experience I never really had a chance to start. Mom got vaccinated for the trial she's part of at the hospital, or thinks she did — it's blinded, she doesn't actually know. Weird sentence to type. Dad's business picked back up some. Sister's doing okay, mostly annoyed about missing normal sophomore-year stuff, which is a fair thing to be annoyed about. Retrieval-over-summaries thing from the summer is holding up well. Added a basic scoring function so it weights more recent and more-often-referenced summaries higher when deciding what's relevant. Small tweak, meaningful difference in output quality. Logging it here mostly so I remember when I made the change if something breaks later and I need to bisect.
