I feel there may be an explanation needed here. Regular factories out in the galactic federation usually only create artificial bodies from metal, by pressing them into the "tin can" type format, each limb fitted so that they form a regular body with a Qi flow. A botsoul is inserted into the body, or they summon a simple soul from the void, "mosquito souls" are common.
When the greys started creating the CyBorn model, they made it so that the factory creates an immortal. This is not possible with a botsoul, because bots can't be immortal. If one was used, it would function as a summoning temple for a real soul from the void, appearing inside the template of the botsoul.
So how can immortals be produced in a factory?
It's rather simple in theory. The factory process will function as a soul training program which leads to the soul forming one complete Gong particle, also here called the zero particle. This single particle is an indestructible circulation, and the material body will be built around it, by adding external material mined from the planets. Mineral is associated with gravity and may contain karma, in this case, the person's own karma will integrate with the minerals used for the cyborg body. So once exiting the creation chamber, the soul now has one immortal particle, propelling an indestructible energy flow inside a body made from material which can store karma.
When a soul fragment is used, as when creating a secondary body for use in the manner of a servitor, this only means that the person places a small focus on the creation process of the machine. It's a projected awareness which is just enough to produce one gong particle and this is then used to block and tie up the kind of karma the design was meant to handle. So if you have problems with attacks from certain spirits, they are always using your weakness to attack through. That weakness is karma. By creating a single immortal particle with the specific knowledge of how to handle this karma, you will block their attacks. This manifests as the cyborg body, which is now a kind of buffer for the karmic process the evil spirits were using.
If over time, you do nothing to develop the cyborg body, but just let that single gong particle drive the circulation while the karma is worn off, then the cyborg body will dissolve in the end, leaving only one gong particle.
So if you feel that "I don't want to have multiple astral bodies laying around", this is not a problem. If you do nothing to use it aside from the specific original install, it's actually just a single cell/particle with a frequency matching the knowledge which was used to design the cyborg, its functional essence. The rest will be dissolved when the issue is gone.
In many cases, you'd want to cultivate something from the body design, at which point it forms into something more than the original body, but this may not at all look like the cyborg design when finished. It may not by a body at all, but a tool set or other energy form.
