36 hours+ sourdough baguette - everything I know in one bread

This baguette has many inspirations: the long cold autolyse from Anis, long cold bulkrise from Gosselin, SD instead of instant yeast from David's San Joaqin SD... With 12 hr autolyse, 24 hr cold rise, the process last at least 40 hours from start to finish, however, very little time is spent on real work, most of the time, I just have to wait and let time do its magic.
