shadcn + Radix Controlled-State Errors : The Open / onOpenChange Pair Rule, asChild Slot, Portal, and modal

Every Radix-wrapped shadcn primitive (Dialog, Sheet, Drawer, DropdownMenu, Popover, HoverCard, Select, AlertDialog, ContextMenu, Collapsible, Accordion, Tabs, Tooltip) shares one state-management contract. Break the contract and the symptom is always one of three : the primitive cannot close, the primitive crashes on render, or the primitive renders in the wrong place with the wrong focus. This skill documents the contract and the six recurring traps that violate it.
