- 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
- Add log_name[16] field to ETCP_CONN structure for connection identification
- Add etcp_update_log_name() function to update identifier when peer_node_id is known
- Update all DEBUG_* calls in etcp.c and etcp_loadbalancer.c to include log_name prefix
- Add DEBUG_CATEGORY_NORMALIZER for packet normalizer debug output
- Change log timestamp format to [hh:mm:ss-mmm.uuu] with microseconds precision
- Reorder debug output: (file:line) function() [log_name] message
- Remove duplicate function names from log messages
- Clean up backup files from pkt_normalizer development
- Add etcp_find_free_local_link_id() function to allocate unique link IDs
- Modify etcp_link_new() to auto-assign local_link_id, fail if none available
- Update INIT_REQUEST (0x02/0x04) to send local_link_id after keepalive
- Update INIT_RESPONSE (0x03/0x05) to include local_link_id
- Parse remote_link_id from incoming handshake packets
- Update protocol documentation in doc/etcp_protocol.txt
- Add comprehensive unit test test_etcp_link_id.c
New packet format:
INIT_REQUEST: [code][node_id(8)][mtu(2)][keepalive(2)][link_id(1)][pubkey(64)]
INIT_RESPONSE: [code][node_id(8)][mtu(2)][link_id(1)]
