Much is left the same from [1], with two notable exceptions: - I took much of Stolee's feedback from [2], since the suggestions were good and we are rerolling, anyway. - I dropped the trace2 calls that write JSON from within the commit-graph machinery in favor of pure "data" writes, which are easier to grep for. This caused some test refactoring and allowed us to ultimately drop the 'test_bloom_filters_computed' function. Hopefully this is it for this series ;). I think that it's in good shape now, and I couldn't find anything in my own inspection that I wanted to change. So, if others feel good, too, I think we should focus on incremental fixes on top of this.
