Worked on the first rib #11, left side. This assembly is a bit more complex, but not a big deal. I did find the rib (WG-RIB-011-L-F-1) was warped a little, but confirmed with other builders that it's normal. The part will straighten out after installed in the wing.
Also found a discrepancy in the drawing. The number of rivets for HW-RIV-153-X-X-0 listed in the BOM is correct (qty 52). However, the callouts are incorrect. The quantity on the detail drawing showing the bellcrank assembly calls for 22 rivets here it should've been 24. This quantity is actually called out twice in the drawing. The callout on the bottom left is correct.
