etcp: TCP-ping через STCP-хендшейк с флагом PING
...
- STCP-хендшейк: добавлен байт флагов (STCP_HANDSHAKE_FLAG_PING), HS_ENC 46→47
- stcp_client: stcp_ping_send() — connect+handshake(PING)+rtt+close; ошибка/таймаут → success=0
- stcp_server: детект флага, ответ с эхо-флагом, мягкое закрытие (close_after_send)
- etcp_connections: etcp_send_tcp_ping(), guard is_tcp/fd и проверка возврата send_ping_raw
- route_connectivity: probe TCP-адресов через TCP-ping (1 попытка), UDP-кандидаты без TCP-сокетов
- tests: test_stcp_ping (success+failure path), обновлена сигнатура stcp_client_connect

etcp tcp: статус-флоу как в UDP + упрощение STCP API
...
- etcp_link_enter_ready_tcp: убраны прямые записи got_initial_pkt/initialized/
links_up/tx_state и fire UP/INIT; переход через etcp_conn_ready +
loadbalancer_link_ready (как в UDP INIT-обработчиках)
- tcp_server_on_link: убран дублирующий gop/session-блок (проверка в
etcp_link_enter_ready_tcp единообразно), sc_init_ctx перед
sc_set_peer_public_key (фикс ctx not initialized)
- stcp_link_connect(etcp_link, addr, port) вместо config-структуры;
stcp_conn.etcp_conn для live-чтения gop/session_id при handshake

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
- 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

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)

stcp: unified transport — etcp_send/bind over TCP via stcp_link
...
- stcp_link.h/c: manage TCP connections through STCP protocol
stcp_server_listen, stcp_link_connect/send/close
rx dispatch goes directly through inst->api_bindings (single table)
- etcp_api.c: etcp_send checks conn->transport_link for TCP path
etcp_bind stores only in api_bindings (no duplication)
- etcp_connections.c: init_sockets creates stcp_server for TCP
init_connections creates stcp_link_connect for TCP clients
tcp_server_on_link creates minimal ETCP_CONN + fires callbacks
- etcp.h: ETCP_CONN.transport_link field (NULL for UDP, set for TCP)
- config_parser: CFG_SERVER.transport field, parsing transport=tcp|udp
- utun_instance.h: struct stcp_server*
- Tests: test_stcp_link (handshake, wrong key)
test_etcp_stcp (etcp_send/bind over TCP)
- Renamed: transport.h/c → stcp_link.h/c (cleaner, no bindings table)
- 46/46 tests pass
