Rehearsing a fix on the same imported board, Claude ran git stash -u on the viewer's review records, so the request note and findings disappeared while it worked. Asked to report only new findings, it spent about ten minutes building a before-and-after DRC comparison by hand. The board copies it left under renders/ then blocked the next verification: "the inputs hold 2 boards". Review context, check results and the design all lived in places the agent treated as scratch.
