saphidandClaude Opus 5.5 08d75e3ffb Contact email: follow-up given with a report is kept and removable; match by rev
- 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.

"""An email address the person chooses to leave, and what it may be used for. Python stdlib only.
Two separate opt-in choices, both off until ticked:
- updates: occasional notices about Frame Control releases and updates
- followup: the maintainer may ask follow-up questions, mainly about problem reports
The address and the choices are kept on this computer (frame_host.data_dir('contact')) and
sent privately to Frame Control's PostHog project as a `contact_consent` event, the same way
as problem reports (frame_report.py), so only the maintainer can read them. Every change
sends a new event under this copy's own random contact id (not the analytics id), numbered
by `rev`, and the highest rev for an id is the one that counts, whatever the clocks say:
removing the address sends a withdrawal with no address in it, and wipes the address from
the local log of what was sent. The maintainer lists who agreed to what with
`python3 ui/frame_report.py contacts`. Nothing here sends email.
A change that can't be sent (offline) waits in the state file and is retried in the
background, so a withdrawal is never lost. The page's one-time prompt is remembered here
too: once it has been shown or dismissed it never comes back.
