Good catch
"With the small stellar radius, Proxima d ... equilibrium temperature may reach 360K,"
NB: Earth's is 255K. Venus 260K, Mars 215K. So this doesn't tell the whole story, but is probably quite hot.

So it has a hot side, a cold side, and an intermediate ring at the terminator.
Probably not very comfortable.
And Mercury is almost tidally locked. Venus will be, before long.
Why couldn't something orbit the star fast without being tidally locked?
Planets with fast orbits are closer to the star and get more drag- hence more likely to be locked.
