Clojurians Log v2

I have a little project structuring question around making bin/kaocha --watch work well. I'm making a library that can use either redis or postgres as its store. I'm trying to structure my project as HugSQL has: where to use the lib you'll have to add a dep for the library, and a dep for your choice of store. I'd like to keep them all libs in the same git repo. My basic goal is that if you're using Redis, I don't make you drag in Postgres dependencies like next.jdbc, and vice-versa. The top-level library leans on a protocol. (Again, very similar to hugsql). The require graph is looking like this, and it's working with bin/kaocha but only changes to lib.core are working with bin/kaocha --watch:

My first try is at https://github.com/rgm/hyak2/tree/postgres-initial/modules. The annoyance I'm trying to squish is that the kaocha watcher picks up changes to $gitroot/src and $gitroot/test fine, but it doesn't seem to be picking up changes in $gitroot/modules/$whatever/src at all. I can work around it a bit just manually re-requiring the namespace from my editor and then invoking a kaocha run all via an nrepl connection. I'm telling my test JVM about the sub-projects via :extra-paths, so I'm thinking maybe that's not quite the right approach (see https://github.com/rgm/hyak2/blob/postgres-initial/deps.edn#L8-L10)
