The Cargo update config points to the repo root ("/") but this repository’s Cargo workspaces live under src/code-validator/guest/ and src/sandbox/runtime/; there is no Cargo.toml at "/". Dependabot will fail to run for Cargo unless the directory is updated to the actual workspace roots (and typically each workspace root is a separate update entry).

The Cargo entry uses directories: (plural) while other entries use directory:. Dependabot’s v2 config uses directory per update; if you need to cover multiple Cargo workspaces, add multiple - package-ecosystem: cargo entries (one per workspace root) instead of directories to avoid the key being ignored / config validation failing.

The npm update config points to directory: "/src/js-host-api", but there is no src/js-host-api directory in this repo (the root npm manifest is at /package.json, and @hyperlight/js-host-api is referenced as a file:deps/js-host-api dependency). This directory should be updated to the actual location(s) of package.json you want Dependabot to manage (e.g. / and possibly /src/code-validator/guest).

There are trailing spaces after the updates: and directories: keys. YAML will still parse, but trimming avoids noise in future diffs and satisfies whitespace-focused linters/editors.
