- Electron crash handlers (render-process-gone, child-process-gone, unresponsive/responsive, process warnings) with a circuit-breaker auto-reload for renderer crashes - Renderer error capture (window.onerror, unhandledrejection, React ErrorBoundary) forwarded to the main log via a one-way IPC channel - Memory-pressure heartbeat measured against the V8 heap_size_limit - Gated DEBUG log level (RD_DEBUG) and an in-memory ring of recent WARN/ERROR lines, exposed via the /errors endpoint and support bundle - Disk-error classification (ENOSPC etc.) on download failures and integrity-check pass/fail logging
