correct me if I'm wrong, and I'm sure you will, but does not NHFS only negate a catch with a player on the fence only when it is flat to the ground, not just partially collapsed? Or am I thinking of another organization?

If partially collapsed, catch. If completely horizontal, no catch. Apparently because a fielder can't be stepping on a completely horizontal fence without being on the ground past the dead ball "line'.

As far as the OP; I believe it is any full foot contact beyond the "line" and the base of the fence is the "line", as she steps on the ground and not the fence.
Although as I said earlier she leaves the ground with her right foot still in play before the catch.

And, portable fences move all the time, so she is still inside the fence even when outside the original fence position.
OUT!

Saw a thread on a similar play. They said home team was up in B7 with 2 out and 2 on base. Ruled a catch, game over. By rule it should have been a walk-off 3-run home run.
