Refresh both AGENTS guides and clarify module purpose, usage, ownership, threading, return values and wire formats in headers. Remove the unused timeout_heap freed_count field and unimplemented getter.
- 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
- node_put/node_update_verified: set online=1 on INSERT (nodes created when conn is UP)
- channel_peers_all: fix peer_needed calculation (atl byte was missing)
- cs_send_channel_join: add proto byte to address serialization matching all parsers
- db_manager: getMessagesSince() now parses m.contentType from JSON (was missing)
- messagelist: setVoiceMessageRoles uses data directly as payload, not re-parsed as JSON
(data is already the 'd' field value extracted by db_manager)
- Add last_msg_at column to channels table
- Update last_msg_at on every message insert (send/receive)
- Parameterize getChannels() with ChannelSortMode enum (Alphabetical/Recent)
- Add getChannelLastMessage() for preview text in channel list
- Add sorting combo to Profile settings page (stored in ui_state)
- Reload channels on message receive when sort is recent
Three diagnostic points covering the gap between ~MainWindow done and CRT exit:
- DbManager: destroyed — confirms local dtors started after ~MainWindow
- SoundManager: static destructor entered — confirms static destruction phase
- main: static destructors done (g_shutdown_sentinel dtor) — confirms ALL statics done
If process hangs, we know exactly which phase failed.
- Debounce timer (300ms) advances lastReadMsgId only when message is fully in viewport
- Unread badge no longer resets on channel select — only when actual scroll reads msgs
- saveChannelState() uses tracked m_lastReadMsgId instead of viewport bottom
- getChannels() reads lastReadMsgId from ui_state (was reading unused channels column)
Store read/scroll positions per channel via ui_state table (key-value).
Draw red +N badge on channel list items for unread messages.
Fix getMessages() to fetch last N messages (was fetching first N).
- Remove is_dm column from channels table (dm detection by member count)
- Rename member name column to userinfo — extensible json_flat format
- Add json_flat.c/h library for compact JSON serialization
- Fix join_sig message format: use ch_x25519+ch_ed25519 instead of channel_id string
- Remove name from join_msg body (now in userinfo via json_flat)
- Update chat_core, chat_sync, member_sync, db_manager to new format
- Add topo_strategy.txt — архитектурные заметки по топологии
- Sound files loaded from filesystem (sound_dir in INI config, absolute or relative)
- Per-event enable/disable + volume stored in DB (ui_state table)
- SoundManager: setEvent(), effective volume = master * per-event
- SoundSettingsPage UI: 4 event rows (checkbox + slider)
- chat_core_save_ui_state() for async DB writes via uasync thread
- DbManager::getUiStateInt() for reading settings from GUI thread
- Default sounds copied to sounds/ dir next to DB, config entries written
- db_sync: rename column author→node_id, open chats.db instead of sync file,
db_sync_instance_add takes table_name directly
- chat_core: remove CREATE TABLE msg_ch_*, remove on_db_sync_insert (74 lines),
remove fallback INSERT in submit_message, add minimal on_msg_inserted
for GUI notification only
- db_manager: update getMessages for new schema (parse JSON from data column),
fix ORDER BY to use author_signature instead of datahash,
update syncCursorNext to parse JSON
- si_register simplified: db_count from same table, no more msg vs sync gap
- Add CreateGroupDialog with group name input
- Generate X25519+Ed25519 keypairs, random uint64 channel_id,
Ed25519 signature, write to DB via uasync thread
- chat_core_create_channel(): create msg table, topo_node_sqlite_channel_put()
- GUI_EVT_CHANNEL_UPDATED notification to reload channel list
- Per-category debug config: debug_level= + debug_categories= in [gui]
- Unified logging via debug_config: all threads write to same file/console
- debug_enable_console(1) to mirror file output to stderr
- DEBUG_LEVEL_DISABLED=-1: truly disable category, NONE=0 fallback to global
- Fix uasync_post under epoll: process_posted_tasks was never called
- Fix MainWindow constructor parameter ordering (dbPath vs debugFile)
- debug_ui.h: append mode ('a' instead of 'w')
