 In `[HS-DESC-FIRST-LAYER]` of `rend-spec-v3.txt` it says:
   The first layer of HS descriptor encryption is designed to protect
   descriptor confidentiality against entities who don't know the blinded
   public key of the hidden service.

 However the HSDir does know the blinded public key, as that's part of the
 `descriptor-signing-key-cert` described in `[DESC-OUTER]`. Should the
 above quote instead be "...against entities who don't know the ''public
 identity master key'' of the hidden service"
