Conundrum

Starfleet seem to be moving dates for various HR-related activities, so

If "A" has a pre-req of "B"
and "A" is rescheduled to occur before "B"
then can "A" occur, or does it mean the Gorse Fox's participation in "A" has to defer 12 months.

If "A" does occur with the assumption of "B",
and "A" requires the presence of GF in "C" when GF is actually in "N",
then will a telephone call provide sufficient presence?

or is GF stuffed?
