The window was carried across a spell, so the results either side of it ended up
adjacent: a monitor at [t, t, t, f, f] when egress dropped resumed at
[t, t, f, f, f] on its first real failure afterwards, crossing the threshold on
results taken before the outage.
Cleared in the producer beside the maintenance gate, which already clears the
window on entering a window, and guarded on its length so it is one write per
spell rather than one per degraded check. The monitor still goes down once the
rebuilt window holds enough real failures.
The two integration tests that asserted the old behaviour are rewritten: one
expected the window preserved through a spell, the other expected failures
either side of a spell to combine.

Checkmate backend
The backend service for Checkmate, an open source uptime and infrastructure monitoring application
This directory contains the backend of Checkmate, which handles data processing, storage, and API services for the Checkmate monitoring tool. The backend is responsible for managing uptime checks, handling real-time alerts, and storing historical monitoring data.
Checkmate's backend is designed to be lightweight and scalable, ensuring reliable performance even with a high number of active monitors.
