Header attention bell
What the Screen Is For
The header bell links staff to required work without returning to Home.
What It Shows and Lets People Do
The bell uses the Home summary but estimates unread totals from its small item samples. It shows a numeric badge, 99+ for larger uncapped values or 500+ at the cap, and displays up to five leading required items with personal actions and a list link.
States and Errors
No sampled required items produces the empty popover message, even when an estimated badge remains nonzero. Summary availability determines content; the component does not guarantee its badge equals the authoritative unread count. That discrepancy remains a finding.
Patterns It Must Respect
Retain the console Popover, accessible count label and shared item row. Advisory and opportunity occurrences do not contribute to this required-work badge.
