No wait, automerge. registryUrls is required: these deps declare `registry = \"kellnr\"`, which Renovate resolves through `.cargo/config.toml` — but that file lives in each repo's `api/` subdirectory and is not discovered, so the lookup fails with `registry index was not found: kellnr` and no update is ever proposed. Pointing registryUrls at the sparse index bypasses that resolution, the same way the @ferrlabs/ npm rule overrides its registry. Auth comes from the crates.ferrlabs.com hostRule in renovate.yml.",
