kidai-snapshot-guard: An Automatic Snapshot and Rollback Plugin for DSH

# Preface The philosophy of DeepSeek Harness (DSH) is "everything is a plugin." The most frequent operations in daily use are installing plugins, updating them, and modifying settings. The risk lies here: once a change breaks DSH, what you need most is the state "before the change." Relying on manually copying the configuration directory before every change is both easy to forget and difficult to guarantee integrity. **kidai-snapshot-guard** automates this: it completes the "Save → Confirm → Restore" loop for snapshots within DSH. Once installed, it just works without requiring you to remember to do anything. # What is it? One-sentence definition: An automatic backup manager inside DSH — save before shutdown, verify after boot, one-click rollback. Plugin by NokorinNishikino.
