I grow cacao instead of bicolor because I can find the seeds and fruit!!! 
I'd love to grow others but can't get my hands on them. Seedlings from EBay are risky at best.

Seller 9waters on etsy is very reliable and currently carries seedlings:  https://www.etsy.com/listing/652257995/

It does look like root rot, yes

Bagged potting mix is often mostly peat moss which is extremely water retaining, and I believe coco coir is itself quite absorbent.  I suggest making chunky, minimally-absorbent material a significant portion of your potting mix.  Something like mulch, perlite, vermiculite, gravel, hydroton, turface, decomposed granite, etc.

The amount of roots lost is not too bad, your tree should recover and regrow new roots if it is otherwise healthy.  When I root prune my container trees I cut off about 25% of the rootball

You can expect a ton of new taste reports this year or next.  Lots of new seeds available in past couple years that should be coming into fruit

Brian, that's a new one, never heard anyone have that issue with one fruit.

It happens all the time, too.  I wonder if it is just a milder symptom of whatever causes the puffiness issue, which also seems to affect one end of the fruit primarily

Here's the thread from last year when I reported my Savannah Cherry (e. calycina) fruiting solo:  https://tropicalfruitforum.com/index.php?topic=51078.0.   K-Rimes suggested it might be a COTRG + Calycina hybrid.  I don't know enough about them to tell.  Last year my COTRG wasn't yet flowering, the only Eugenias I had flowering were uniflora, pitangatuba, and this calycina.

The seeds from these fruit all sprouted, though I threw most of them away as this is a common variety. 

It is fruiting again right now with many fruitlets and some mature fruits already, and while this year I have been cross-pollinating all the eugenia flowers that are blooming at the same time this is still the only mature calycina, the rest are COTRG, uniflora, or others

My solo calycina set fruit.  The seeds seemed normal and I have a couple of them growing new plants.

  I've never heard of guabiju, though, can't speak to that one.

By "flushing out" I assume Epicatt2 is talking about leaching - https://en.wikipedia.org/wiki/Leaching_(chemistry), using water to dissolve accumulated minerals in the container soil and remove them.

Even my in-ground, in-greenhouse rollinia looks a bit yellow in the winter.  It will bounce back to healthy green as it warms up and we get longer days.  Yours might also

Tropicaltoba isn't it likely that your minneola is itself grafted?  Do you know its rootstock?  I know you can have interstocks but I don't know much about their usage.

My in-ground light-green/dark-green variegated minneola produced poor fruit.  It was soft and watery and the tree was overly vigorous.  This one was from Harris Citrus, not sure what the rootstock is the label doesn't seem to say.  I removed it and prepared a replacement non-variegated minneola on flying dragon rootstock.  I am growing the new tree in a container for a few years and then putting it in the ground also, hoping for better results.  I have another containerized variegated minneola that produces decent fruit but I will probably go with the non-variegated type long term. 

Some of the best citrus I've ever tasted were minneola tangelos from the grocery store, but they seem to be very inconsistent.  I really don't want to give up on them yet.  Maybe if it is a poor producer for many years I will.

#1 looks like Mammea americana

I think so too

I don't think you actually need to remove the shell, the idea is to crack it enough to let water in more easily.

The name, most likely. People want to grow chocolate and thats the one with the name.  If the genus was cacao and it was 'cacao cacao' and 'cacao mocambo (bicolor)' I bet the others would be more popular.

I have a cacao for exactly this reason, I didn't even know about the other types until long after I got it.  I have tried a raw cacao pod and its seeds and pulp and I agree neither are very palatable.  I got for the novelty of "Can I grow a chocolate tree?"

Does bicolor require hand pollination?  That is a huge negative I found out about cacao after I got one

Hah, impressive to see a graft right into the trunk of such a large tree.  I hope your graft takes and you get a super strong growing marang out of it

My in-ground sumo makes huge fruit, grapefruit sized, and with prominent neck.  My minneolas have been variable, one was in ground one in container.
