Lead Journey

Every property this lead's browsing session looked at, before or after they left their number.

The join key is the session, not the address on the lead row. That is what makes the ordering irrelevant: the events keep arriving on the same session after the number is submitted, so a person who asks for a call and then goes looking at three addresses shows all three, and a person who looks first and asks after shows the same thing. Neither has to tell us anything.

Returns {linked, addresses, device, channel, first_seen, last_seen, events}. linked is false when no session could be tied to this lead, which is the honest answer for a lead created before this link existed, or by a visitor whose browser refused session storage.
