- Ticking follow-up questions on a report makes that address the contact
email (follow-up ticked, update choice unchanged), so Settings shows it
and Remove my email withdraws it like any other.
- Reports carry contact_rev; the inbox takes a report's follow-up
permission back when a later change from that copy (higher rev) no
longer agrees, whatever the clocks say.
