F12-TS: No
Rationale
The selected Tailscale packet filter explicitly drops multicast destinations, and its peer delivery path sends to an identified peer rather than a multicast forwarding group.
Assessment method
Pinned source inspection and official purpose statement; no runtime experiment
Source context
Tailscale magicsock and packet filter, official privacy statement
Outstanding qualification
Applies to the selected TUN service. An added application fanout or multicast tunneling system is outside this profile; layer 3 alone is not the reason for No.
