Andrew Lamb Weekly-ish Open Source plan - 2025-12-08

[alamb]

This is my weekly plan, mostly for my own organizational needs (as I am dropping too many things). I am making it public in the hopes that helps others to see what I am working on -- also I spend so much time in github the interface is very familiar to me and I can cross link all the issues I am working

(it is also my excuse as to why I haven't reviewed many good looking PRs)

Notes to myself: a duplicate entry unchecked means I need to go back and re-review
