The capacity plan grouped by date, for reading every site at once.

The capacity plan grouped by date, for reading every site at once.

One row per day, with sites an array of the rows api.capacity_plan returns for that day, each one an object with the same fields. A range across any number of sites is one answer, where the row-per-site form would need paging.

p_filter narrows it to some of the work, read exactly as api.capacity_plan reads it.
