Shelter Protocol is an append-only log that is stored in a key-value database. I recommend watching the talk if you haven't already, it should answer your questions. Regarding storing Vue (or any other frontend framework), the answer is gonna get a bit technical (sorry, we haven't documented this on the website yet). This is a curiosity for how we happen to be using Shelter Protocol in Group Income (which uses Vue). Vue.js both is and isn't saved to the contract. Each contract manifest has two versions of the contract: one "complete" contract containing all of the code necessary for reproducing the state, and one "slim" version that has any large dependencies passed in to the contract at runtime. Group Income uses the slim version so that the contracts load quickly, but it's also possible for anyone to reproduce the state of a Group Income app independently, without using Group Income, by loading the "full/complete" version of the contract because all necessary dependencies are bundled in.

>an append-only log that is stored in a key-value database. Yeah, that's definitely not clicking in my brain at the moment. I guess I need to actually watch/listen to that video rather than skimming the slides. For storing code: yeah, I guess a more "storage polite" version of this would be to serialize the "engine" of whatever you're doing, rather than its presentation. That can often be quite small, certainly in comparison. Would it be possible to simply store e.g. a git repo name + sha, and then clients download as needed? Or do storage-providers need to be able to execute any of this (beyond enforcing key permissions)?

The server stores all of the events and all of the contracts in a content-addressable way, in whatever key-value database it is using. It does not execute any of the contract code though, no, that's done locally by clients.
