A start and a finish sent seconds apart can reach Sentry in either order, and a start that lands second is never closed, so a fast rollup could be reported as a timeout on a night it succeeded. Hnefatafl's monitor did so nine nights in fifteen on the shared host. One check-in at the end cannot race; a run that hangs sends nothing and is marked missed. Installed on the host by hand; the next deploy installs the same files. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GwFKMuQnPAEHJ5yA1q4orh
