- The example-images library subfolder goes through the folder guard like
its root, so its canonical (normcased) form matches the media check on
Windows for a library name with capitals.
- A failed trigger-word load is retried by a running node only after
TRIGGER_RETRY_SECONDS, not on every prompt run.
- A review whose discovery cannot list a folder says so (folder-unreadable,
the folder's name only) instead of a generic error.
