I don't see how that would touch the NAND-AID directly, I only see that it could touch the 3V3 wire.
But if it would only touch that it shouldn't be able to damage the SD, it would only short the 3V3 to GND, in which case the SMC should shut off the Wii U with a red blinking LED. And even if 3V where shorted to any other contact of the the SD or short any pin of the SD to GND it should survive that.
Maybe the card just failed by itself.
Anyway I always use the PVC isolitaed wire for the 3V3 and also try to route it as close to the eMMC as possible.

On the MLC2SD I moved the 3V3 connection, to avoid the connection of the shield entirely: https://github.com/jan-hofmeier/mlc2sd

It can't touch the NAND-AID directly. I believe it would have to be that 3V wire. However like I said I made sure it was as close to the eMMC as possible before I partially reassembled the console for testing. My picture doesn't show its final location because I took it immediately after soldering it in place. The wire is enamel coated, and unless there is a hole or some other damage to the enamel coating, no current should be able to leak out and short anything. I have used it for years on hundreds of repairs where traces had to be bridged due to liquid damage and its always worked for me.

As for the SD Card, I started thinking the same thing, perhaps it was just defective. As for the red blinking LED. This console didn't have one, it just had a solid red LED and when I pushed the power button it did nothing. 

Oh so you have a NAND-AID design as well. V10lator also contacted me and showed me a design he has which appears to be an improvement over the one that I have been using.

hm solid red would mean either the power button doesn't work or boot0 can't load boot1 from the slc, which would hint to a problem on the SLC. But since it works agai, the SLC must be fine.
Maybe the card itself caused a short with prevented the SLC from working, which feeds of the the same 3V3

Also did you see this? https://gbatemp.net/threads/ultimate-wii-u-troubleshooting-guide-system-memory-error-160-0103-stuck-wii-u-screen-stuck-factory-reset-black-screen-after-stuck-update.642339/

No I didn't see this. Thank you for the link. It would seem you have done almost all the troubleshooting already. This will definitely come in handy!

Do you mind if I make a sticky post with links to your stuff related to the Wii U repairs? Actually you should be able to make the same post. Perhaps you can share them all with me? I am asking because I think it would be helpful for me and I am sure others who may find this forums might find it helpful as well to have a single thread where they can reference your tutorials/guides as well as your github work.

Feel free to post links to my stuff

I believe (unless I am confusing you with someone else) that you also created tools for use with the Wii U that you share using a github? If this is correct I am unable to find the github links, perhaps you can share them and I will add them to them master post for reference material for repairing Wii U here

The repair on this Wii U is complete. I finished testing it today and its fully working. As you can see in the system information picture below this console has a 64GB SD Card installed.

I added features to some of these tools for eMMC repairs. UDPIH and the orginal recovery is by GaryOderNichts, I added the NAND dumping stuff and the initial launch option.
Similar for minute, which shinyquagsire forked from some other project and adopted it to the Wii U, I added a few features and married it with ISFShax. ISFShax was found by rw_r_r_0644, I just changed the integrated boot1 stage to make it more stable.

I thnk I linked to all these tools in my guides, else you find my forks on my github.

Also I will order 50 mlc2sd soone (since less isn't really cheaper) maybe you want some. Maybe you could make a video about soldering it, I could link to in the tutorials: https://github.com/jan-hofmeier/mlc2sd
Also the GND VIA isn't just structual, it is also the GND connection for the SD, without it, the SD wouldn't work
