- call_on_conn_status: only end call when its own data conn drops
(INDIRECT call was killed by unrelated topo_group_connect conn DELETE)
- conn_mgr: run REVERSE and INDIRECT in parallel after DIRECT fails;
reverse is preferred (indirect defers via indirect_ready until reverse
resolves). REVERSE timeout 15s -> 3s.
- retransmit DIRECT_REQ / EXCHANGE_REQ every 1s (idempotent, same request_id)
to survive packet loss (router RST dropping stale-channel requests)
- replace main.phase with reverse_active/indirect_active/indirect_ready flags
- add diagnostics to trace the parallel flow
conn_mgr: src node_id вместо conn->peer_node_id, препенд ETCP_RT_ID_CONN_MGR к dgram, bind CONN_MGR после etcp_router_init
call: guard CALL_ST_CONNECTING при accept
- sock_match: единая классификация сокетов (DIRECT/NAT/LOCAL) и адресов (PUB/PRIV/UNREACH)
- eim приравнен к direct; на приватный адрес — только с приватного интерфейса;
оба EIM за одним NAT (одинаковый публичный IP) — только через LAN
- topo_node: LOCAL-сокеты рекламируются (INTERFACE), private скрыт,
NAT-адрес не рекламируется для strict и при оффлайне
- ntp: флаг reachable по циклам + пере-анонс nodeinfo при смене доступности
- cm_direct_add_links / ncd_create_links / conn_match_candidate_sockets на sock_match
- test_sock_match: unit-тесты классификации и сопоставления
standby.h/c: duty-cycle ACTIVE/SLEEP, standby_wait() будит в burst сразу,
в SLEEP — до следующего burst; notify_network_activity для раннего пробуждения.
Интеграция (по флагу UTUN_HAVE_STANDBY, десктоп без изменений):
- conn_mgr: bg_ping/candidate_ping в SLEEP defer через standby_wait
- route_connectivity: probe_node откладывается (PROBE_STATUS_DEFERRED)
- topo_group_connect: пауза между попытками — активный режим 1с, фон standby_wait
- jni_bridge/ConfigProvider/NetworkActivityMonitor: set_active + сетевая активность
- chat_setting: standby_active_sec/sleep_sec/min_sleep_sec
+ юнит-тест test_standby (31 проверок)
- Добавлен device_type (1 байт, CLIENT_TYPE_*) в INIT_REQUEST и INIT_RESPONSE
- Добавлен keepalive_interval (2 байта) в INIT_RESPONSE
- STCP handshake расширен с 43 до 46 байт (device_type+keepalive)
- negotiate_keepalive(): оба desktop/server → min, иначе (есть mobile) → max
- keepalive_interval вынесен в UTUN_INSTANCE для использования в handshake
- stcp_client_connect() принимает device_type и keepalive_interval
- peer_device_type/peer_keepalive_interval передаются через stcp_link в ETCP_LINK
- ntp_node_time.c: respond to TIME_SYNC only when peer is unsynced (not always)
Prevents infinite 10-byte ping-pong that ate bandwidth when both sides synced.
- pkt_normalizer.c: add in_total_pkts/in_total_bytes increments in
etcp_input_ready_cb (real send path), matching pn_packer_send (test path).
- conn_mgr_core.c/conn_mgr_priv.h: full INVITE_INFO_RESP with channel info
- 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
- CONN_MGR entries: replace dynamic array with ll_queue (hash=256, key_size=8)
cm_find_entry now O(1) via queue_find_data_by_index
cm_ensure_entry uses queue_entry_new + queue_data_put_with_index
cm_entry_cleanup removes from queue and frees entry
- TOPO_GROUP_NODE: replace handles** array with single CONN_MGR_HANDLE*
remove topo_node_handle_register/unregister/count — dead indirection
nq->handle = h / nq->handle = NULL in all call sites
- TOPO_GROUP_NODE: remove dead fields dirty, best_socket, tranzit_data/count
dirty replaced with local variable in nat_detection.c
tranzit_data removed from wire format (TOPOMSG_NODE), serialize, deserialize
update struct layout: one field per line with comments
- CM_V6_ANY for :: socket (matches all v6 addr classes)
- sin6_scope_id from s->netif_index (not from local_addr where :: has scope=0)
- getnameinfo in stcp_link_connect to preserve scope_id in addr string
- scope_id in cm_invite_tcp_connect, ncd_create_links, connect_create_links_v6, cm_bg_ping_to_node
