Error codes

It includes application codes explicitly associated with one HTTP status in a public Admin, Storefront, or Auth route.

It is not exhaustive per endpoint: responses originating in dependent services, framework validation, OAuth, or infrastructure are excluded.

1 code was omitted because it is associated with more than one HTTP status; it will not be published until the contract is unambiguous.
