dsh-session-import

You switch to another machine, another deployment, a fresh workspace — and the conversation you just had with DeepSeek Harness is stranded as a .zip or .jsonl export with no built-in way to bring it back. dsh-session-import closes that loop: it parses DSH /export archives, validates event structure and SHA-256 fingerprints, then registers the content as a brand-new DSH session, all through an Import conversation dialog on the new-session page with drag-and-drop and file-picker support.

Before you commit, a preview panel shows title, message counts, tool activity, turn structure, original workspace, model, and session state. You can pick a target workspace, rename the session, keep original timestamps or restamp to now, and selectively sync model and reasoning effort, agent preset, permissions, sandbox, approval policy, and plan mode. The plugin always allocates a fresh session ID and will never overwrite an existing one; if persistence, workspace attachment, or load validation fails at any point the entire import is rolled back so no partial sessions are left behind. On the ZIP side it enforces CRC-32, central-directory metadata, entry bounds, and local-header names, and outright rejects encrypted, multi-disk, and ZIP64 archives before anything touches the session store.

If you move between machines, share context across staging and production, or simply treat /export output as your session backup, this plugin turns that workflow into a reliable round-trip. It makes zero outbound network calls, never touches API keys, and parses uploaded files entirely in local memory. Combine dryRun=1 validation with open=1 instant resume and the migration friction drops to nearly nothing: verify first, then pick up exactly where you left off.
