- http/httpraw: cap header slice growth to pre-allocated capacity, fix benchmark to reuse Header across iterations (0 allocs/op) - internal/ring: replace TODO panic comments with invariant explanations - tcp/conn: document truncated-frame offset check - tcp/handler: replace TODO with net.ErrClosed on RST-closed connection - internet/stack-udpport: filter incoming packets by remote IP address when configured via SetStackNode; skip filter for IPv4 multicast destinations (class D) so mDNS and similar protocols work correctly Generated with LLM assistance.
