Flax and oatmeal soaker: revamping my entire process

Hi, for this bake I decided to completely change up my process. I did this in part to fit my schedule, since I decided to make the dough late at night on a Friday, and in part to try a longer bulk ferment and baking the loaf straight from the fridge. Oven spring wasn't as strong as in my other bakes, but it might've been due to 1. a sleepy starter, 2. an overly long bulk ferment, 3. shaping and proofing in a bowl as boule, instead of making a long batard.
