 - The qBittorrent client must merge incremental torrent patches with the prior
   snapshot so active-transfer rows retain their name, size, progress, and state
   when only throughput changes.
+- Active-torrent entries must show each torrent's qBittorrent share ratio
+  (uploaded ÷ downloaded) alongside its size and completion progress.
 - The service UI should expose polling settings, current status, stale-data state, a manual `Run now` action, the shared selectable chart windows, an **All values** option that fetches every retained speed sample, and paginated scheduled-action history.
 - Scheduled-action runs should use dedicated generic records, retain at most 30 days or 1,000 runs per service/action, and never store secrets or raw credentials.
 - Disabling a qBittorrent service pauses polling while retaining history; deleting the service purges its samples and scheduler history through the existing cascade-delete behavior.
