 ** notes
-
+- discord adapter is now a thin HTTP client of the backend; it no longer imports or configures yt-dlp
+- `YOUDIS_BACKEND_URL` controls which backend the adapter targets
+- progress updates are currently implemented by polling `/jobs/current` and DMing only when the summary changes
+- legacy auth/user-management commands were removed from the active adapter path and should be cleaned up formally in `2.0.3`
+- `.env` is now supported for local/dev convenience, while real environment variables still override it in prod/docker
+- submitting via DM doesn't work
 * [ ] 2.0.3: remove deprecated discord-bot functionality (2)
