Bill 43

A document that led to the focused efforts by virtually all ZSC Repositories (see the ZSC article) to construct the first fully autonomous robots capable of housing a very complex sapient mind.

Bill 43 was initially proposed by a Repository called 28-E. This repository made history as the first entity to manage to unify almost every other repository to a degree that was impossible before Bill 43. It was important as it would allow those contained in the repositories to leave these eternal computational structures. Indeed, it eventually led to the formation of the ZSC and that factions space travel. Despite its massive influence, it is not known even by residents of 28-E why the document was named as such, because it took a lot more than 43 iterations to create this current version.

This bill did, however, take the Repository 28-E hundreds of thousands of iterations to get correct, each one requiring a vast amount of computational power, and the people of the repository had to work very hard for this. The bill itself also described a possible way to build the robots, as well as a blueprint, which formed the vast majority of the document's wordcount. The entire document spanned tens of millions of words as the design and manufacturing process were both extremely complex. The immense computational output of the repositories would mean that other repositories would be able to calculate this solution very quickly and prove it correct, which is largely why it was so widespread as opposed to other documents to achieve the same thing.

Bill 43 even had the foresight to determine what nations would form after the end of the Repository age and predicted with reasonable accuracy any conflicts that might begin. The Repository age ended in such a specific way to attempt to reduce conflict as much as possible.

Despite the end of the age, some very few people have remained behind in the repositories and eventually ended up dying. The issues the repositories were facing would be impossible to fix. They stayed behind for various reasons, such as the repositories allowing for more customisation of every individual's reality as well as various ethical reasons and the desire to remain in a world they are more familiar with, though they would be decaying by this point.

For historical reasons, many copies of the document is kept by the ZSC. Unsurprisingly, it forms the largest physical book known to the ZSC and is too heavy for a single individual to lift easily so it is often built with a motor designed to flip large numbers of pages easily. 

Now, the models of robots proposed by Bill 43 are largely obsolete and have been superseded by more modern, more powerful robots with a higher computation, greater efficiency and generally improved construction.
