Avg alert density(5.7.4)

Average share of each project's active issues that raised a compliance alert in the week, an issue counting once however many alerts it raised. High alert density without scoring improvements usually means alerts are firing but not acted on—a process bottleneck rather than a detection problem. This card reads the latest complete week and names the week it read. A density of 0.0 is a measurement and reads green—issues were raised and none of them triggered an alert; a dash means no project carried issues to measure.
