“File-diff visualization between checkpoint time nodes for DeepSeek Harness: a read-only timeline + per-file line diff over the dsh-checkpoint-rewind checkpoints storage domain, with preview-first rollback (restore workspace files from any time node, single-file or whole-node), exposed as /diff and /rollback commands, a JSON HTTP API, and a GUI panel (session header action + shell overlay).”
