Running benches/export.rs
The export ran one query per row. Batching the load fixes it.
●editsrc/db/rows.rs●bashcargo test exporttest export::batches_rows ... ok
test export::keeps_order ... ok
test export_batch::one_query_per_batch ... ok
The export ran one query per row. It now loads each batch in a single query, which the benchmark puts at 14 timesfaster. The new regression test and all export tests pass.

The double boost stopped working in the last build. Find out why and fix it.
Miso reproduced it on the Sol 1-2 route
Juniper traced the boost charge to the thrust check
Pixel edited 2 files, added a double boost test
ReasonFixed. The thrust check reset the boost charge every frame, so the second boost never fired. I flew the Sol 1-2 route to check it, and all 8 checks pass.

On it. Pulling July to September from the incident log and the uptime dashboards.

Can the payments outage get its own slide? Leadership will ask.
Reason APP
Done: 12 slides, with the payments outage on its own. Uptime was 99.97%, and the data behind every chart is in the two CSVs.
