- 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
- config_updater.{h,cpp}: single implementation — config_update_in_lines
for batch updates + config_update_option for file-level. REPLACE/APPEND
modes, section auto-creation
- node_config.cpp: generateIdentity() now derives node_id via
SHA256(pubkey) (like sc_derive_node_id_from_pubkey) instead of random.
save() uses config_update_in_lines for line-level update when file
exists, saveFull() only for new file and addServer/addClient.
Removed duplicate findSectionBounds/updateOptionInSection/configUpdateOption
- test_config_updater.cpp: Q_ASSERT replaced with VERIFY macro — Q_ASSERT
in Release mode does not evaluate the expression, causing false positives.
Test now works in both Debug and Release
