Module executor and pure-serve: 027's 4a, a message's rows holding lists: rows whose records hold lists are read, as the message arrives, by stage 3's decoder into the event's lists (value_take into the rows' list), the event beginning with them; the JSON edge reads an object's array as its record's objects, 64 lists deep at most (items_of: an item's lists encoded first and the item moved down over them); the load no longer refuses them; a hole closed: the decoder read past the end where fewer than 4 bytes were left for a length (size - at - 4 wrapped around), unseen while it read only what was stored; unit test nested_rows (three events, four rows not whole changing nothing); check server_trees (300 random forests over HTTP against a Python model walking them in the same order, a require refusing some, a list field not an array, a field the record lacks and 65 lists deep refused, a restart); counts: b30 against b29 within 0.001% but BFS with batches +0.12%, the bank's queries -0.00% to +0.23%; 027's stage 4 planned in six steps (4a to 4f, the counts it starts from, 4b in two commits) and 4a as made; 008 on nested rows
