I had a question about the pictures at the bottom of the post. Is this an example of "wire wrapping"? If so what mechanism is actually holding the wire securely

The wire is wrapped around the posts several times, with no other mechanism. https://en.m.wikipedia.org/wiki/Wire_wrap https://en.m.wikipedia.org/wiki/Wire_wrap has a good close up picture of one connection and a description of the details (including some info on how this forms a reliable connection)

  Friction. You can use a wire wrap gun that takes a bit of wire - fine-gauge, solid core, and stripped on both ends - and tightly wraps it around the square pin. A handful of turns provide plenty of surface area for the square corners of the pin to "bite" into the wire. Kind of like how in old western movies when the cowboy wants to park his horse he just loosely wraps the reins around a fencepost. It's secure enough to keep the horse from wandering off. Here's a video showing a manual wire wrap tool: https://www.youtube.com/watch?v=lG5oKLrG7R0 https://www.youtube.com/watch?v=lG5oKLrG7R0
