topo_group: асимметричный старт BGP (JOIN_GROUP) + вынос group_id/flags из TOPO_NODE
...
- UTUN: BGP инициирует только сторона-клиент ([client]) и явные etcp_connect;
сервер добавляет пира по JOIN_GROUP (фикс обратного маршрута: сервер не
создавал узел клиента из-за дедупа senders_list)
- topo_group_new_conn: conn_add_path до дедупа; handle_request_table без add_to_senders
- TOPO_NODE: убраны group_id/flags (shared-реестр), передаются в topo_node_serialize
- routing/control_server: явный TOPO_GROUP_UTUN
- CHAT: гейт по peers_* (get_member_channels) + пассивное add/remove в member_sync
- tests: тесты адаптированы (route_ping ждёт registry+v4_addrs)
- chatgui-android: voice_recorder_init в utun_bridge_voice_start (idempotent)

chat: BGP-driven address sync, member identity verify, join_sig fix
...
- Адреса узлов вынесены из wire-протокола member_sync/merkle/join/welcome
в BGP/topo_group: node_addresses теперь пишет только topo_node_sqlite_addrs_put
(источник истины ni->v4/v6_addrs), классификация config_type/nat_type в sockmeta
- Жёсткая анти-подделка: node_id=derive(x25519), ed25519 сверяется с доверенной
таблицей nodes, NODEINFO node_id/pubkey mismatch отклоняется как forgery
- Единые member_sync_build_join_msg (112Б) и member_sync_build_update_msg:
устранён баг _verify_join_sig (join_ts по смещению 80 вместо 104, длина 104→112),
который рушил приём мемберов; все 7 мест подписи/проверки join_sig через хелпер
- Единое обновление своего мембера chat_core_update_my_member (вместо sync_my_addresses)
- Android standby: пауза таймеров (broadcast/db_sync/merkle_sync/chat_sync) через standby_wait
- name[16] → name[MAX_CONN_NAME_LEN] с truncation-warning в парсере
- conn_mgr: etcp_connect_cancel_by_node (use-after-free при отмене invite),
промоушен conn в ncd после успешного invite
- Android GUI: foreground-gating опросов, сохранение портов интерфейсов, фикс udp-log flush
- chatgui: персистентный db_path; мелкие DEBUG-логи epoll/pool

stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test
...
- 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

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

refactor: STCP connections as ETCP links (is_tcp)
...
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

fix: memory pool alloc mismatch in tests, db_sync SEND_DATA buffer overflow
...
- test_etcp_router_reconnect, test_etcp_connect, test_stcp_traffic:
replace u_calloc with memory_pool_alloc for TOPO_SOCKMETA4/TOPO_ADDR4
- db_sync.c: fix req[14] -> req[15] — SEND_DATA request header is 15 bytes
(type:1 + from:4 + count:2 + vp:4 + want_from:4)

etcp: replace connections linked-list with indexed ll_queue, add state/ref_count lifecycle
...
- Remove ETCP_CONN.next linked-list, UTUN_INSTANCE.connections list/count
- Unified connections in single ll_queue indexed by peer_node_id (0=pending)
- struct conn_queue_entry { peer_node_id, conn* } for uniform queue data
- Connection lifecycle via etcp.c: create→pending, conn_ready→indexed, close→detach+deferred free
- Close split: phase1 detach from external world, phase2 deferred via uasync_call_soon
- etcp_conn_set_peer_node_id: reindex on ID change (WARN)
- etcp_conn_ref_take/free: blocking close until refcount returns to 0
- Remove chat_connections — use unified connections queue directly
- Update all iteration/search patterns across 40 files (src + tests + chatgui)

TOPO_BGP -> TOPO_GROUP: multi-group support
...
- Renamed TOPO_BGP to TOPO_GROUP with topo_group_id (64bit)
- Added TOPO_GROUPS container (ll_queue group_list) in UTUN_INSTANCE
- Memory pools moved from TOPO_GROUP to TOPO_GROUPS (instance-level)
- Default group: TOPO_GROUP_UTUN = 0x8000000000000000
- topo_groups_get_default() searches by group_id, not just first entry
- All topo_bgp_* renamed to topo_group_*; function signatures updated
- Files: topo_bgp.h/c -> topo_group.h/c

refactor: переименование route_node/route_bgp в topo_node/topo_bgp
...
Файлы: route_node.* route_node_lmdb.* route_bgp.* -> topo_node.* topo_node_lmdb.* topo_bgp.*
Структуры:
- ROUTE_BGP -> TOPO_BGP, ROUTE_BGP_CONN_ITEM -> TOPO_BGP_CONN_ITEM
- NODEINFO -> TOPO_NODE, NODEINFO_Q -> TOPO_NODEQ, NODEINFO_PATH -> TOPO_NODEPATH
- NODEINFO_ROUTES -> TOPO_NODESUBNETS, NODE_CONNECTIVITY -> TOPO_CONNECTIVITY
- wire: NODEINFO_MSG -> TOPOMSG_NODE, NODEINFO_IPV4_* -> TOPOMSG_*4 и т.д.
- memory: NI_IPV4_* -> TOPO_*4, NI_IPV6_* -> TOPO_*6
- ROUTE_SUBCMD_* -> TOPO_SUBCMD_*, ETCP_ID_ROUTE_ENTRY -> ETCP_ID_TOPO_ENTRY
Функции:
- route_bgp_* -> topo_bgp_*
- nodeinfo_* -> topo_node_*
- route_node_* -> topo_node_*
- route_node_lmdb_* -> topo_node_lmdb_*
Смысл: отделение механизма формирования топологии узлов от IP-роутинга.

route_node: refactor NODEINFO — separate protocol/memory structs, linked lists with memory_pool
...
- NODEINFO_MSG (protocol, packed): added flags byte + group_id field
- NODEINFO (memory): ref_count, linked list heads instead of inline arrays
- NODEINFO_ROUTES: separate struct with linked list subnet heads
- NODEINFO_Q: node*, routes*, tranzit_data*, hop_list* as separate mallocs
- 6 memory_pools in ROUTE_BGP for NI_* linked list items
- ni_list_count() universal counter via _ni_head cast
- nodeinfo_serialize/deserialize for protocol <-> memory conversion
- NODEINFO_FLAG_SEND_SUBNETS controls subnet data in protocol
- group_id defaults: utun=NODEINFO_GROUP_UTUN(1) with subnets
Fixes:
- deserialization: data+2 instead of data+sizeof(BGP_NODEINFO_PACKET)
- memset: start after ll_entry to preserve ll.size
- hop_src: subtract hop_count*8 to point at correct dynamic offset
- same-ver branch: remove_path(conn) instead of remove_path_by_hop(peer)
- double-free in route_bgp_remove_conn/process_withdraw
- conn_mgr_add_alien_node: rewritten for new structures
- all test files updated for new API
