- 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
- etcp_router: SVC_ROUTE_HDR (+8B), ETCP_ROUTER_CONN/TRANSIT_QUEUE хеши расширены под group_id
- Все caller'ы (proxy, routing, conn_mgr, nat, chatgui, tests) обновлены
- topo_group: глобальный реестр TOPO_NODE по node_id, ref_count=0 при создании
- BGP-обмен активируется для всех групп (а не только дефолтной)
- Протокол: group_id добавлен в WITHDRAW/TABLE_REQ/TABLE_COMPLETE/ERR_GROUP_MISMATCH
- Per-connection коллбэки заменены на instance-level conn_status
- msg_transport полностью удалён из проекта
57/57 тестов
- Add ed25519_public_key[32] to NODEINFO struct for pubkey distribution
- Add ed25519_public_key[32] to ROUTE_BGP (derived from X25519 privkey at init)
- Add ROUTER_FLAG_SIGNED (0x08) to SVC_ROUTE_HDR flags byte
- router_send_one_flags: when is_signed, sign [hdr][payload] and append 64-byte sig
- etcp_router_recv_cb: verify Ed25519 signature when ROUTER_FLAG_SIGNED set
- New API: etcp_router_conn_send_signed()
- Drop signed packets if sender node not in routing table or no Ed25519 key
- 5 unit tests in test_etcp_router_unit.c covering OK/tampered/unknown/no-key/short
