Eric WagonerandClaude Opus 5.5 db682814ea The rollup's last line names the traffic it counted, and the rollup and the backup check in once, when they end
The closing summary still named the old parser's variables, so every run
wrote its row and then died on the print, and Sentry was told the night
failed. It reads the shared parser's counts now. The check-ins become one
at the end with the run's duration: a start and a finish seconds apart can
reach Sentry in either order, and a start that lands second is never closed.
