- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll - stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close - utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP), add deferred drain in both Phase J and L - stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39, exchange ed25519_pubkey in both handshake directions - etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb - chat_sync.c: fix lk->conn NULL dereference for TCP links - test_stcp.c: update stcp_server_create/stcp_client_connect callsites - tools/chat_tcp_test: change transport udp→tcp
