"Set mit Preis" / "Nur Set mit Preis" collapsed every block into an inserted "Gesamtumfang pauschal" row, nulled/removed all lines and cleared the user-defined set structure. Both modes now convert every still-unconverted top-level set: the set line takes the sum of its subtree, its members render without a price (setprice) or are removed from itm + items (setonly); lines outside a set stay individually priced and several sets stay separate lines. Nested sets are priced once via their top-level set. One conversion primitive (ConvertSetHeader) now backs all three triggers; item.setprice is a no-op on an already-converted set (a repeated delta used to reset the set price to 0). The header's price_net is mirrored too (flat PDF path unit price), and Build treats a null total_net as "no price" like the flat path. The editor checks for a set before offering the modes and the menu entry stays available for sets added later. ADR 0009 is superseded by 0019; INVOICE_SET_PRICING.md rewritten accordingly.
