Stored app board end

Stored end date for each OpenRouter app board in the digest. apps_popular ends 2026-10-27. apps_trending ends 2026-10-27. session_cost stores window_end_date 2026-10-25 and does not store end_date, so it stays off this page. The label is the stored board name. The value is the stored meta.end_date. Both stored end dates are 2026-10-27, so the bars are equal. These dates are separate from the rankings window end date and from the app board start date. A board with no stored end date stays off the page.
