Same page. Same data. Two years of UX debt apart. Drag the handle — everything on the left really shipped, and everything on the right is how we fixed it. Twenty problems, root-caused, with receipts.
Every number below comes from the DS-Brain decision logs — the append-only memory of 100+ waves of work. This was the starting line.
Each slide rebuilds the broken version so you can experience it — disagreeing pagers you can click, an invisible number you can hunt for, a TAB key that skips the fake link — then flips to what shipped, with the why · how · what.
The real OISidebar IA, 80 pages in 5 template families, the drawer law, and the drift nobody could see.
