More on the karpef. What if you demarcate the space with another partition, in addition to the original partition that demarcates it. Also, the inheritance rules for the convert (ger), or acquiring the property from the ger, are a little unexpected. To take possession, one would have to actively improve the land. Plus, the case of a woman who doesn't improve the land to take possession in the accepted way - so the halakhah didn't accept her claim. The challenging additional factor is that one may not know what one does as a mourner until this case is a done deal. Also: moving beyond the karpef, to an orchard that is adjacent to a mansion, when a wall of the mansion falls down. But it was also the wall that helped enclose the orchard - now what? Plus: A cryptic insult by R. Papi to R. Bavei, for speaking cryptically. And one more case that sets up a Shabbat gathering in a pavilion, through the orchard, from the mansion. Plus: Doing more than is required just might make it required.
