- CategoryPanel: the left tree — All Downloads / Unfinished / Finished, then Categories and Queues populated from category.list / queue.list, with per-node task counts. Selecting a node emits a TaskSelection. - DownloadFilterProxy: QSortFilterProxyModel keyed off that selection. Client-side for M1 (the whole list fits); asTaskFilter() exposes the equivalent TaskFilter for a server-side download.list once paging lands. - MainWindow: menu bar (Tasks / Downloads / View / Help) sharing QAction objects with the toolbar; QSplitter [panel | table]; Delete with a confirm; Resume/Pause All; View menu toggles the panel. Actions disabled while offline. - Counts are computed off a throttled 400 ms timer, not the 4 Hz progress path. Fixed a debounce-vs-throttle bug found in the first screenshot: restarting the timer on every progress tick meant it never fired and the status bar sat at "0 of 0 downloads". - First-run column widths that fit the content. - tst_downloadfilterproxy: nodes filter to their own rows, the Finished/Unfinished split is correct, and the filter is dynamic (a row that finishes leaves the Unfinished node with no re-list). Verified against mockd --tasks 400 (screenshot: tree counts 75/84/89/83/69 sum to 400, status bar "400 of 400, 21 active").
