047: "the leaf is the commit" (feedback 009) set up before it runs: today's store measured as the base (baseline.py, 046's shim and journal: list bytes a message, the log and images, at 1 / 16 / 256 messages a commit: entries' appends 65.5 / 15.7 / 12.4, the bank's transfers 122 / 35.6 / 30.1, the tree apart), and a byte-accounting model (model.py) of commits writing the leaves they changed in memory's own bytes (leaf 296 to 1,320 B, inner node 680 B, cow; tail appends in place past every kept snapshot's count; inplace, which may not be, to show why), its bars written before the run (appends at most today's, sparse updates at most twice, no write a kept snapshot sees) and what a pass for appends with a miss for updates would mean (two units, not one); 046's Run takes pure-run's arguments; 045's keyed file says 24 refused, not the 26 its commit said
