What gets processed
Monitoring starts after you choose a source and create a filter. Several topics can share a chat, or a filter can be limited to particular groups. Imported history supports recaps and is not presented as a new lead.
A truthful status
The /status command distinguishes incomplete setup, connection in progress, working search, a pause and queue delay. An empty feed only means there are no saved matches; it does not prove source access.
Source access
A public chat address does not guarantee that a connected account can read its messages. A private group may require an invite and manual approval or captcha handling by the service owner.
