Does deps expansion do :deps/prep-lib preparations before trying to resolve a package's transitive deps? I imagine not since calculating the dependency graph and constructing the classpath are 2 separate things, and preparation may require a package's deps to already be resolved for compilation. For context, I'm trying to see if I can manage Git lib deps with Nix instead of deps.edn by using :local/root as an escape hatch. https://clojurians.slack.com/archives/C02S1GEKU4C/p1738438617792579
