Live ball appeal - missed home plate

[HugoTafurst]

I'm confusing myself.
I could use an answer for ASA, NFHS and NCAA fastpitch.

BR beats the throw to home (by several steps - in fact there is no tag attempt) but misses home plate.
F2 mis handles ball and goes to fence to retrieve it as BR (unaware that she missed plate) heads to her dugout.
F2 tosses ball to F1 in the circle area as defence fans start shouting "throw it home", she missed the plate", etc.
By now BR is in the crowd of congratulations at her dugout.
Ball reaches F2 who has foot on plate (it is clear to me that she is appealing the missed base) and (accidentally) tags BR before she can re-touch home plate.

Question, at what point (if any) can this live ball missed base appeal be accomplished by tagging the base only (and making the appeal known).

Is it actually entering dead ball territory?

Where is it described in each of the books?

Thanks
