This counter tracks Coding Violations accumulated at the Section layer over the current one-day interval, the daily rollup of the fine-grained BIP error count. An admin cares because the daily CV total gives a sense of overall error density across the day even when no single 15-minute window crossed an alarm threshold. For example, a section with a moderate but steady CV count every day, without ever tripping the 15-minute ES threshold, suggests a link that's degraded but not yet bad enough to alarm — worth proactive attention before it worsens.
