027's 4f-3b: no fixed count of records or of their fields in all: the header's u16s alone (16 and 128 before); a stored list's record graph (PureLayout) holds a few records itself and more on the heap, 256 at most (an image numbers them in a byte), an image or a checkpoint not written then without room for it; a record's 16 fields kept, the list engine's width (a leaf's columns, a run's columns and narrow cells, the arrays' and packs' columns), to be widened with the lists' shapes sized to their fields; unit tests: 20 records of 10 fields (200 in all), an item of the last appended; a stored list whose six records each hold a list of the next saved and read back after a restart (its graph on the heap); counts: b41 against b40 with batches BFS +0.12%, without BFS -0.09%, the rest within 0.001%; the bank's queries (s40 and s41 in turns, six each) within 0.09% (the first three's in_credit +1.16% its spread: 2.75% between runs of one build); 008 and 027
