Auditorium is a local desktop app: it makes no network requests except downloading ML models on first use of the features that need them, and its local servers/IPC are restricted to the app's own processes. Reports about that boundary (renderer sandbox escapes, IPC path traversal, model-download integrity) are especially valuable.
