The single keepalive flush bound to both `visibilitychange → hidden` and `pagehide` self-conflicted on tab switch: visibilitychange fires on every tab/app switch with the page still alive, the keepalive POST advanced the server's `created_at` to a fresh `now()`, the client discarded the response (no listener), the local `lastSync` stayed at the old value, and the next foreground autosave sent that stale timestamp → server saw `created_at > last_sync` → conflict modal for the user's own background-tab write. A still-pending debouncer task made it worse: it fired a second runner POST after the keepalive with the same stale `last_sync`, the second self-conflicted too. Split into two paths: - `visibilitychange → hidden` → `flushOnVisibilityHidden`: route through the normal runner pipeline. The page is alive, so the response can land and `setLastSync` keeps the baseline current. Call `debouncer.cancel(key)` first so a queued keystroke can't double-fire with the same stale `last_sync`. - `pagehide` → `flushOnPageHide`: keep the `keepalive: true` raw fetch for the genuinely-going-away case (the JS context is torn down, the response is necessarily discarded). Same `debouncer.cancel(key)` guard. On the next mount, the route's `recordRemoteSync(query, draft_saved_at)` reseeds `lastSync` from authoritative server state before any user edit can fire a save.
