-Are LXNAV products with AHRS available by software key allowed? They are not on this list:
-The "restricted device policy" claims there will be a list published of acceptable software. And unacceptable software. That might be useful. Where is it?
-This antique discussion thread implies that XCSoar (which as of 2017 still has a not-very-good AH option) is illegal. Is it? Do I have to run some forked version of it?
-In the year 2017 is anyone in the US competing using XCSoar as a flight computer? On a phone with no SIM card installed?


Since no one here is interested in answering these questions, is there anyone at SSA I should be emailing? Calling? Sending a letter?

The SSA "Guide to Competition" also says exactly nothing about flight computers, instruments, etc....

I have been away from my desk for a few days and am sorry for reply that is too slow for your needs.
The relevant information is available on the SSA web site.
