Build faults: every structural notice starts a 72h repair clock. Not fixed at 72h: press BARRICADE once the base is barricaded — that starts 24h more. Still not fixed: DELETE BASE. MARK FIXED stops the clock at any point.
Flag warnings: a flag-down notice gives 24h to raise the flag. Flag back up: MARK FIXED. Not raised: DELETED records the deletion and gives you the deletion notice. Each step gives you the Discord message to post.
