Why this tripwire exists

Home network block-rate weather — % of all DNS queries the profile blocked in the window. Stable band day-over-day means blocklists are doing their job; a sudden swing means either a blocklist went stale (filter not catching) OR a device is pulling an unusual mix. Tripwire arms after 14 daily snapshots accrue, then flips amber on >2σ deviation from the rolling 30-day mean.
