Well, if you think about it this way - most of the Elder Artefacts were created by Jas using the Stone of Jas. Given that she refers to the Stone as "My future. My sacrifice" this would lend credibility to the theory that the Stone was indeed her own hard-boiled egg.
In the Elder Chronicles, Jas is referred to as:
Original message details are unavailable.
From life is born experience, wisdom and intelligence. The matron is nurturing and caring. Thus came Edda-Jas.
From Jas, the thought to lead them all. The preparation, the plan, the execution. To look to the future.
Given the names "Codex" and "Template" I think it's pretty clear that these two items were created by Jas to fill the void for both her "experience, wisdom and intelligence" (Codex) and "The preparation, the plan, the execution" (Template) when she was not part of the next cycle of existence.
I would anticipate that both of these artefacts would need to be on Gielinor, for the next generation of Elder Gods to discover and use to create the next universe.
