Why do large exports fail?
Export completion fell from 94% to 79% when v1.2.4 shipped on Sep 7, and recovered to 92% with v1.2.5 on Oct 7. The drop is almost entirely exports over 500 MB. Sample data from a fictional app, written by a coding agent from the SQL below.
Finding: on v1.2.4, nearly 9 in 10 exports over 500 MB failed, mostly out of memory. Smaller exports also lost about 9 points. v1.2.5 restores small exports to 95%, but files over 500 MB still fail a third of the time. Next: stream large renders instead of buffering them, then re-run this report on the next release.
