One-command backup & restore of DSH user data with a visual Settings panel: scheduled auto-backup, sha256 verification, hardened restore with auto-rollback, typed sub-backups (--types skills), credential redaction into a local vault, GitHub sync for cross-machine moves, and an out-of-process rescue channel that works even when the host won't boot. /backup doctor checks and repairs corrupt session logs from a known-good backup; migrate-check statically predicts which sessions a host upgrade would break (frozen event-list rules, filename/generation mismatch, hardlink support, legacy credentials layout) and the credential sentinel preserves pre-migration copies before the host rewrites them; smart backup snapshots before host upgrades and quarantines corrupt logs before rotation. macOS/Linux/Windows.
