- Add regex filter input to the Alerts dashboard that filters displayed hosts on every keystroke; invalid regex turns the border red - Initialise the filter from ?filter= in the URL query string - Change _build_url() to produce /alerts?filter=<hostname> so notification links (Pushover, email, Matrix, etc.) land on the alerts page pre-filtered to the alerting host Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
