e2e: AES-128-CCM encryption via BGP router (ROUTER_FLAG_ENCRYPTED), ECDH key per peer-pair from NODEINFO pubkeys, cache 8 entries
...
- etcp_router.h/c: new flag ROUTER_FLAG_ENCRYPTED (0x04), etcp_route_send_encrypted(), inflight/retrans/send_q support
- utun_instance.h: e2e_ctx_cache[8] — per-peer sc_context_t cache with derived session key
- topo_node.c: topo_node_sign_self() — single point for Ed25519 self-signing of NODEINFO
- topo_node.c: fix stale x25519_self_sig after address update (topo_node_sign_self call)
- nat_detection.c: fix stale x25519_self_sig after in-place socket meta modification
- test_etcp_router_unit: 5 E2E tests (basic round-trip, no NODEINFO drop, tampered, cache reuse, ENCRYPTED+SIGNED combined)
- builds clean, 70/70 tests pass

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)

Android: unify DB access via JNI/JSON, fix instance lifecycle, add restart + health check
...
- ChatRepository: remove SQLiteDatabase (READONLY 2nd handle), use JNI→shared g_cc.db (FULLMUTEX, like desktop)
- instance_lite: simplify start/stop lifecycle — start no longer waits for init, stop waits for thread exit with timeout, add internal restart (no thread kill)
- Restart trampoline: reinit UDP log target on config change
- Health check: ping/uasync_post round-trip every 3s, red dot on stall
- Settings: Restart instance button
- Fix: g_inst check instead of g_running for is_running()
- Fix: SharedFlow replay=1 + proactive DB_READY check in ViewModel

android: fix key regeneration, Clear DB, uasync eventfd, udp log from config
...
- jni_on_event: fix JNI_EDETACHED — AttachCurrentThread/DetachCurrentThread
- u_async.c: pipe→eventfd for reliable cross-thread wakeup
add process_posted_tasks in poll() path, fix EINTR (saved_errno)
- bridge_debug_hook: keep udp_log_write, remove mutex from udp_log
- memory_pool.c: alloc/free logs INFO→DEBUG (reduce spam)
- instance_lite.c: chat_event_set_handler before ensure_keys,
KEYS_GENERATED events, fchmod 0600 on keys.conf,
UDP log from config [log_udp] section, regenerate_trampoline
- config_parser: parse [log_udp] ip/port
- NativeLib.kt: remove callbacksSet, simplify init/stop/destroy
- ChatViewModel.kt: unified event callback in init, pubKey StateFlow,
requestRegenerateKeys, clearState fix
- SettingsScreen.kt: pubKey.collectAsState(), Clear DB via restart()
- HeadlessService.kt: remove setUdpLogTarget (now from config)
- android_udp_log.c: simplified — no mutex, buffer+send+timer in one thread
- utun_instance.c: NULL-check tcp_connections before destroy
- chat_event.h: +CHAT_EVT_KEYS_GENERATED 11, -NODE_CHANGED
- logreceiver: UDP log receiver tool

android: real utun instance + SQLite channels + reactive logs + QR join
...
- instance_lite.h/c: full uTun stack from INI config text
(keygen, uasync, UTUN_INSTANCE, SQLite, chat_core/sync, BGP, etcp_router)
- jni_bridge: nativeStart/Stop, nativeJoinChannel → chat_sync_connect_from_invite,
nativeSubscribeLogs, C logs → logcat + Kotlin LogManager
- Kotlin: direct read-only SQLite queries (channels, messages),
ViewModel with live event callbacks, reactive LogScreen (tail -f),
CameraX QR scanner with proper lifecycle, JoinChannelDialog
- HeadlessService: generates INI config from Kotlin settings → C instance
