<li>Daily summaries aggregate the hourly snapshots for the day; monthly summaries aggregate daily summaries for the month (or hourly snapshots if configured).</li>
<li>Snapshots are registered in `snapshot_registry` so regeneration via `/api/snapshots/aggregate` can locate the correct tables (fallback scanning is also supported).</li>
<li>Reports (XLSX with totals/charts) are generated automatically after hourly, daily, and monthly jobs and written to a reports directory.</li>
