 - **Watched bots**: bot tokens you add in the web client. Each one logs in over MTProto (`auth.importBotAuthorization`, the same door a bot-login client uses), backfills the history of the bot's dialogs once and then keeps the incoming stream: who writes to the bot, what, and when. A separate authorization, so it does not take `getUpdates` away from whoever runs that bot over the Bot API.

 ## Parts
 
 - `backend/` - `userbot` (kurigram, the capture loop and jobs), `watcher` (kurigram again, one bot-token session per watched bot) and `api` (FastAPI: the web API, the MCP server, and the built frontend as static files).
-- `frontend/` - SvelteKit, `adapter-static`; a chat client over the archive: folders, chat list, thread with media, versions and the deleted messages inline, search, stories, presence graphs.
+- `frontend/` - SvelteKit, `adapter-static`; a chat client over the archive: folders, chat list, thread with media, versions and the deleted messages inline, a feed of what was deleted or edited across chats, search, stories, presence graphs.
 - `docker-compose.yml` - includes `backend/` (Postgres with TimescaleDB, `userbot`, `api`) and `frontend/` (the dev server); profiles `external` and `services`.
 
 ## MCP
 
-Read-only: `list_watched_bots`, `get_bot_stats`, `get_bot_updates`, `search_messages_tool`, `list_chats`, `get_chat_history` (with deleted messages included), `get_deleted_messages`, `get_message_versions`, `get_media`, `get_callbacks`, `presence_history`, `presence_stats`, `get_peer_history`, `get_person`, `get_stories`, `get_annotations`, `list_watches`, `list_alerts`.
