Actors with PII events(5.4.4)

How many distinct contributors have generated detected events, counting both detection arms (email pattern and phone-shaped digit run). Useful for spotting structural training needs (many actors with isolated events) versus targeted ones (a few actors with many events). Read it next to the per-actor chart, which shows which arm each actor's count came from. The count is split by the type of account Jira reports: people's accounts form the headline, and apps such as Automation for Jira, service-desk customers and accounts Jira returned no type for are counted beside it, never inside it.
