Weekday × hour (UTC) slots ranked by average engagement from the project's OWN past results. Use when choosing scheduled_at.

Read signal before the order. A ranking always comes back and is only advice when there is something to rank on: none means no engagement has been recorded at all, so first place is wherever the sort left it; thin means a slot rests on one or two posts (each slot carries its own samples); ok means every slot has three or more.
