Obvious (?) fair catch questions

[The Roamin' Umpire]

Fed rules.
Situation 1: During a free or scrimmage kick beyond the neutral zone, R99 is leveled just after he touches the ball in flight, but before completing the catch.
Situation 2: Same thing, but R99 has made a valid fair-catch signal.

In situation 1, is there a foul? If so, what is the rule justification? 6-5-4 says that KCI restrictions do not apply after R has touched the kick (beyond the NZ for a scrimmage kick).

In situation 2, everyone has a flag, but again, what's the rule justification? Fair catch is defined very nicely in 2-9-1 as protecting the receiver from being blocked or tackled. 6-5-3 tells us again that only the receiver making the signal is afforded protection. There are multiple places (6-5-1, 9-3-3) that give us a penalty for when the receiver giving the signal makes a block. But none of 2-9, 6-5, or 9-4 (personal fouls) lists a penalty for hitting a receiver who has given a fair catch signal. Obviously, a hit after the catch is completed is a dead ball PF, but it seems to me there's a small window in which we have no rule coverage for calling a foul.

That said, I'm throwing the flag anyway.
