They need to be tied down not left in the air or shorting across frame/test pins used in manufacturing. I always use PVC or Teflon coated wire often using different colors to help express what its function is. Power Black/Red, switch lines Yellow, and Blue/Grey for everything else. I only use bare copper when I'm following the trace's path (soldered down). Here's a good source: Mouser - 26 AWG Hook-Up Wire. I use solid core when possible.
Sounds like you'll need to do clean up here ;-{ I hope you didn't pay to much for the repair.
Patching wire routing is an art form and you do need to tie it down. Here's an example of a well done job:
Enamel/Epoxy coated wire is designed for coil wrapping where you are trying to get the wire as close as possible. It is not really suitable for patching. I know people use it and in some cases its likely the only sized wire you can fit. But you can't always tell where the coating ends and the bare copper starts. Many years ago you could get green coated wire so it was more pronounced (it looked brown). I don't know if you can even find it any more. In some ways its harder to work with as you need to scrape off the coating and the method used can effect the strength of the wire.
Solid wire in any form can suffer fatigue just from a small nick and how the wire is stressed. The wires insulation can also not have the needed insulative effect needed. Yes, shorting is the biggest issue, but its also the signals leakage/crosstalk you need to also consider.
When I was going to school we used the terms 'Outer-World' and 'Inner-World' it made the two spaces more understandable:
Outer-World
In the digital world here we have the usual mechanical & physical issues in placement of the wire/s routing and we also need to consider the fragility of the patch.
Inner-World
The signal or current load traveling within the line/s. The current load will effect the size of the wires gage needed and if we need a solid or stranded wire. We also need to conceder the issues of signal integrity and leakage/cross-talk. All of which can effect the routing of the wires.
