What it may solve
One-command backup & restore of DSH user data: /backup commands and a visual Settings panel — destination, retention and excludes edit live and apply without a restart. sha256 verification with hardened restore (path-traversal and symlink rejection) that auto-rolls-back on failure and reports a result receipt; scheduled auto-backup that survives restarts; daily/weekly tiered retention; /backup doctor checks and repairs session logs from a known-good backup; smart backup takes pre-upgrade snapshots on host version changes and quarantines corrupt session logs before rotation can destroy good copies; out-of-process rescue channel (zero-dependency rescue web UI dropped into the backup dir, works even when the host won't boot); archive download route and GitHub sync for cross-machine moves. Credentials are redacted by default — .credentials.yaml and .env stay in a local vault rather than the archive, and a cross-machine restore lists what to re-enter. macOS/Linux/Windows.
