- conn_mgr_init(TOPO_GROUP* group) — работает внутри заданной группы
- conn_mgr_connect_node: загрузка узла из SQLite если нет в BGP-таблице
- topo_node_sqlite_node_load(): загрузка TOPO_NODE (ref=0) из БД
- cm_start_phase_direct: db_loaded-ветка — перебор всех адресов без NAT-фильтра
- cm_cleanup_db_node: удаление TOPO_NODEQ из группы при неудаче, только если нет путей
- cm_start_phase_indirect: исправлено зависание при best_candidates==0 (cm_deliver_result)
- conn_mgr_set_direct_timeout_ms(): конфигурируемый таймаут фазы DIRECT
- conn_mgr_destroy до etcp_router_destroy (исправлен порядок)
- test_conn_mgr: +2 сценария (DB-успех, DB-недоступен), проверка topo_group
- find_third_node: use nd->inst->connections instead of group->senders_list
- on_conn_up callback auto-calls trigger_checks (no BGP handshake needed)
- Remove group param from link_ready, request_check_all — nat_detection self-sufficient
- Remove trigger_checks + route_ping_cancel_for_conn from public API (internal only)
- topo_group.c: removed last nat_detection_trigger_checks call — completely decoupled
- Header: 4-line summary, no duplicate function list, 7 public functions
- Assign ETCP_ID_NAT_DETECTION = 0x02, etcp_bind in create, etcp_unbind in destroy
- nat_detection_receive_cbk: own packet dispatcher (PING_REQ/RESP, NAT_INFO/CHECK_REQ)
- 4 handle_* become static internal, send_nat_check_req stays static (dead code)
- Rename TOPO_* -> NATDET_*: all subcommands, structs, message types
- Remove all NAT/PING constants and structs from topo_group.h
- Remove dispatch lines and subcmd_name cases from topo_group_receive_cbk
- API: clear sections (lifecycle/internal service/control/test helpers)
- trigger_checks: marked with IMPORTANT note about call order (must be after add_to_senders)
