I have the same issue as you. It's because of the way `merge` is defined in `mergePersistedState`. It uses `Object.assign`, which doesn't work recursively (so doesn't care about nested objects)....

I deleted the `.cargo` directory under `f3discovery/src/07-registers`, and now `cargo run` is successfully using the appropriate config from `f3discovery/src/.cargo`.

This issue is a duplicate of another older issue: https://github.com/rust-embedded/discovery/issues/379 The solution is to delete `07-registers/.cargo` directory. This issue can be closed.

Note that `BUILD_VIA_INSERTS` must be set to `ON` in `CMakeLists.txt` to repro the issue. In particular, this means we need this PR: https://github.com/lanterndata/lanterndb/pull/114 to repro.
