.spr.yml

hmmm... shame to ignore this, there are settings here that depend on the repo, not the user. right? for merge queue, for example?
is it possible to "split" .spr.yml to repo/user settings?
or maybe possible to use environment variables in .spr.yml, so only each user's .bashrc needs to add metadata for the specific user in environment variables, and then you can commit .spr.yml?
out of scope, please add a TODO here in a comment to investigate this

#[test]
fn test_error_unavailable_contract_address_format() {
    let error = StateError::UnavailableContractAddress(ContractAddress::from(10_u128));

(non-blocking FYI: this should work too)

Suggestion:

let error = StateError::UnavailableContractAddress(10_u128.into());
