What changed

In WhatsApp/WebChat/Telegram settings you can choose Open, Filtered or Known contacts only. The filter asks for a name, reason and YES before opening the bot; it does not verify authenticity. The first message with a link or instruction delimiter is preserved for review. In the Inbox, owners and managers can mark as customer, report spam, block and unblock.
Telegram also supports these policies. Filtered WebChat requires configured Turnstile and server validation before opening a session; without configuration the chat is unavailable. Unblocking never replays outputs or notices from before the block, and merging customers preserves restrictions.
Pre-card admission, the complete form flow, retention, metrics and digest/Flow coverage remain pending. No challenge was validated with live credentials.
