An Urbit ship should maintain itself so that a user does not need to intervene to keep it running properly. In order for this to be true, the ship needs to be reliable, handle upgrades properly, and manage its resources (e.g. RAM and disk space) efficiently.

Multiple bugs were introduced by a major release in mid-2022, called the "gall request queue fix". `~norsyr-torryn` is fixing these bugs.

~norsyr-torrynThe Ames vane could be shorter, easier to read, more performant, and easier to prove correct.
Current
Ensures chronological move processing order, allows for a new concept of simultaneity among vane activations, and should be easier to reason about than depth-first move processing.

There are a number of cases where Arvo can crash in a way where it gets into an inconsistent state (e.g. Clay does not always handle Ames crashes properly) or gets stuck on something and fails to continue to make progress.

Arvo updates itself over the air, but current Vere does not. We should let the binary update itself by downloading a new version and replacing itself with that, instead of forcing the user to run terminal commands to stay up to date.

If Vere hits a nondeterministic error on replay, it should retry instead of giving up and crashing.

Improving the Arvo/Vere version negotiation will increase release rate by reducing the amount of work it takes to release a new Kelvin version.

The filesystem I/O driver doesn't handle filesystem errors properly, which can cause desynchronization between Unix and Clay. Fixing this would improve developer experience and general reliability.

Applications often have bugs when a peer breaches. Modifying the userspace/kernelspace API to give Gall agents clearer information about breaches should improve application reliability and developer experience.

There are a number of places where Vere crashes where it should instead handle the error and continue.
Future
Standardizing application protocol versioning in the kernel should improve developer experience and lead to more applications behaving correctly across upgrades, thereby improving user experience too.
