"""The Stats page's "Full history: done / requested" ratio counts the SAME channels on both sides — the
ones this user asked full history for. The numerator used to count every subscribed channel whose
back-catalog was complete (another user had asked, or the channel was short), so the page read
"342/329". "Channels without full history yet" still counts every subscribed channel. Needs the DB."""
