## Description

<!-- SECTION:DESCRIPTION:BEGIN -->

_GitHub: created 2025-09-28 · updated 2025-11-10 · closed 2025-11-10_

When applying all rules, we currently apply each rule independently on the entire database. This means that it takes a significant amount of time to apply all rules.

Instead we should be able to compose a single query to apply all album rules, and a single query to apply all artist rules.
