gates / gates (push) Successful in 26s
- 09 §3: decision 19 (the copy method is chosen by a bake-off) and 20 (the full-system backup waits for the update leg, inside its window; built later). - Bake-off on 9202, docmost / romm / vikunja: both methods pass every case; the folder copy wins because an app with no database server gets no dump, so dump-and-load would need the folder copy anyway. 1-5 s extra downtime, ~420 MB/s, disk = the volumes. - R-645 filed: lifting an update hold by hand lets the recovery unit be re-captured with the failed definition within seconds. Documents and evidence only; product code follows in the controller.
