Start with the panic stack and inspect sing-box/route/conn.go around connectionCopy at line 239, then compare the called sing/common/bufio code at conn.go:110. Look for a way to reproduce the nil buffer or writer condition on OpenWrt with sing-box 1.11.1. Done means the failure is understood and the panic no longer occurs under a reproducible scenario.
