 ## Common Pitfalls
 
 - The `dev_scripts/reset.sh` referenced in the nix devShell hook does not exist in the repo.
-- `share/rhemawave/audio/*.wav` is gitignored — do not commit audio assets.
+- `share/radiantwave/audio/*.wav` is gitignored — do not commit audio assets.
 - The `vendor/` directory is committed — always run `go mod vendor` after `go mod tidy`.
 - CI runs on a self-hosted Forgejo runner, not GitHub-hosted runners. Workflows source nix via `/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh`.
 - The `packaging/` directory contains a kiosk-specific updater script and is not part of the main build.
