The X11 source only re-read the active window on _NET_ACTIVE_WINDOW changes, so switching a browser tab — which changes the window title but not the active window — was invisible. All the time on the new tab was credited to the stale title (e.g. reading a Consume article showed up as time on the Keel tab). Mirror the Windows sensor: poll the active window every 750ms and emit only when the window or its title changes. A shared, display-free pollLoop carries the change-dedup and is unit-tested for the exact regression (a title-only change must emit). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
