You left out the part about verifying PGP signatures (!).

You're excused this time because the MAR format allows for (possibly
multiple) signatures and Tor developers do sign their MAR releases.  I
also expect the Tor Browser to fail tightly in case of unsigned/invalid
MAR files.  But for those that already decided what degree of trust to
put where, and are going the manual route anyway, checking a PGP
signature ex ante is in order.
