DSH Lifeboat: A Process-Free Secure Boot, Fault Isolation, and Recovery Tool for DSH Configuration Files

DSH Lifeboat is a DSH plugin maintained by IoveCelestina, designed to address the diagnostic challenges caused by Harness Loader crashes or Profile configuration failures. It uses a standalone Rescue server to isolate and recover from faults. Its core features include dual-mode interaction via Web UI and CLI, intelligent diagnostics based on snapshot cloning and an "upper-bound-first removal" algorithm, and full fingerprint verification with an atomic recovery mechanism. The plugin remains accessible when the main process crashes, supports one-click rollback, and can generate JSON-formatted diagnostic reports. After installation, the diagnostic service can be enabled. It requires a Node.js environment and provides a reliable fallback for Harness Profile.
