New instances of progressive aspect in Colonial Valley Zapotec

I was very pleased to find some more instances of the progressive aspect marker in Colonial Valley Zapotec texts this morning, since it is not generally known that this morpheme was present in the language at this stage.  Smith Stark (2008), for example, doesn't include any mention of it in an otherwise comprehensive overview of the Colonial Valley Zapotec aspect morphology.

These new examples involve the verb 'do' and 'be sitting'.  It's interesting that with the first verb, the form in the text is

ca-g-oni

where the /g/ looks like a reflex of the potential aspect.  Thom Smith Stark argued in a (2004) paper that the progressive evolved from a construction that involved a verb of position followed by a verb in the potential.

The function of hua- in Colonial Valley Zapotec

In Colonial Valley Zapotec texts, we often see an aspect marker that is spelled something like hue or hua before the verb.  The function of this marker is a bit uncertain, and in the modern Valley Zapotec languages that I am most familiar with, it is no longer in use.

The following passages, from an 1823 Catechism, however, seem to show that hua is not strictly speaking an aspect marker, but another kind of morpheme that precedes the aspect prefix /r-/.  

In modern Valley Zapotec /r-/ is habitual, but in Colonial Valley Zapotec, /r-/ had a wider range of uses.  Perhaps at this point in the 19th century, the combination huari was the normal way to indicate repeated actions?

Contrast the following where the /r-/ appears without the hua.  Here we seem to have more of an eternal 'gnomic' style reading of the clauses:
