Status: the board is not routed yet—50 airwires remain. The neckdowns exist, but three currently overlap foreign copper (QON, D+, and VBUS), so I’m correcting that pre-route blocker before starting autoroute.
The neckdowns have been regenerated, but preflight still flags D+, REGN, and VBUS as dense-pad exceptions despite the narrower net rules. I’ve made the required rule fix attempt; I’m proceeding with the main route and will handle those three connections surgically afterward.
Progress update: 7 neckdowns are regenerated and routing rules are applied. Autorouting is temporarily blocked because another auto-layout job is currently active; 50 airwires remain, with D+, REGN, and VBUS reserved for surgical cleanup afterward.
