The cursive connection anchor type was defined with a couple of assumptions in mind: a) that the letterforms visually connect, and b) a single pair of entry and exit anchors was sufficient for all connections. What this means in cascading Arabic is that one can’t define a entry anchor on an initial letter without all other initial and medial letters with exit anchors connecting to it.
The isolated alif needs to be handled as a special case. In theory, one could define a contextual cursive connection lookup, in which the entry anchor on the initial letter would only be active when preceded by an alif. I have not tried this, though.
