What's in flight, sliced per person and per cycle — the working set someone actually touches this week, not the whole backlog.
A per-person, per-cycle slice of "in flight" work — narrower than BOARD, narrower than ROAD. What one person is actually carrying right now.
The same Tasks DB, filtered to In progress / In Review, grouped by owner and by whatever cycle convention the team lands on.
Probably native Notion saved views — a filtered, grouped view per person may cover this without any generated artifact at all. If Notion native does the job, that's a win, not a failure: SPRINT may never need to exist outside Notion.
