Research Mode was the opt-in behind the estimated GLP-1 drug-level curve:
turn it on, read a disclaimer, get the chart. The chart stopped consulting
the flag several releases ago and has painted for every account since, so
the switch on Settings → Advanced changed no screen in either position. An
inert control that promises to hide a chart is worse than no control.
The curve is simply part of the medication page now. Gone with the switch:
the acknowledgment dialog, `/api/auth/me/research-mode`, the shared status
DTO and its gate helper, the disclaimer-version stamp, the query key, and
the three user columns the acknowledgment wrote (migration 0321). The
Privacy page's second button pointed at the retired control and goes too.
Settings → Advanced is now what it reads as: reset the data, delete the
account.
