Moving a sub-category to a new parent corrupts per-category topic counts
Small and already known — noting it here mostly so it's on the list. Re-upserting a category to a new parent (via /-/v0/upsert-simple) messes up the old and new parent categories' topic counts. It's marked BUG // harmless in the source, so you've flagged it as cosmetic.
I'll take your word that it's harmless in the sense of not corrupting content — it just makes the displayed per-category counts wrong after a move. Worth a fix eventually so the numbers stay trustworthy, but low priority relative to the rest of this cluster.

Evidence. The
BUG // harmlessmarker on the category-move path is atSitePatcher.scala:830.Verified: source read.
Suggested fix: recompute (or decrement-old / increment-new) the affected parent categories' topic counts when a category's parent changes during upsert. No repro steps beyond "upsert a sub-category with a changed parent and compare the counts before/after." This is adjacent to Ivan's existing note about the one-level subcategory cap under Talkyard Limitations — same subcategory machinery, different symptom — so cross-referencing rather than duplicating.
