@imrascal/dsh-archive

A DeepSeek Harness (DSH) plugin that manages archived sessions and the trash from the settings panel.

• Archived Sessions: review sessions that are hidden from the sidebar but keep their records; restore them individually or all at once, or move them to the trash.
• Trash: review deleted sessions; restore, permanently purge, or empty the whole trash.

Deletes are reversible: deleting a session moves it to the trash (~/.dsh/trash); only purge / empty trash are permanent. Live (running) sessions refuse deletion with a clear message.

Install

dsh plugin --profile web add github:imrascal/dsh-archive

Or from a local checkout:

dsh plugin --profile web add file:C:/path/to/dsh-archive

Restart the app after installing (the host half loads at boot), then refresh the page — the section appears under Settings → Archived Sessions.

dsh plugin forwards to pnpm, so pnpm must be on your PATH.

How it works

This feature originally lived as in-box patches across 12 files (dsh-workspace, dsh-session-persistence-jsonl, dsh-host-apiproxy, dsh-client-runtime, dsh-client-ui-workspace, ... — reference diffs in patches/). This plugin re-implements it as a standalone package with a dual-path design:

Path	When	Behavior
Native	host/client already carry the archive API	the client calls ctx.workspaces.unarchiveSession / trashList / ... directly — same RPC + store-frame sync as the in-box implementation
Fallback	an app update reverted host or client to stock	the host half patches at runtime: adds the trash layer to sessionPersistence and the archive API to workspaceRegistry; the client talks to the plugin's own /dsh-archive/session HTTP route

So the feature survives app updates: trash data lives in ~/.dsh/trash (data, not code) and the archive set lives in the workspace registry's persisted state. Whatever the update does to the packages, the plugin feature-detects at startup and fills in whatever is missing.

Layout

dsh/index.js   host half: persistence trash layer + registry archive API + /dsh-archive/session route
dsh/client.js  browser half: "Archived Sessions" settings section (settings.section slot), no build, react only
cordis.patch.yml   bundle mount declaration
patches/       reference diffs for the in-box host patches (the client patches are replaced by this plugin)
scripts/       eval-check.mjs (client factory eval) and host-logic-test.mjs (host backend lifecycle)

Migrating from an in-box patch (optional)

If your DSH install already carries the local archive-management patches (as this repo's dev machine did), the plugin and the in-box patch would register the same archived-sessions section. To migrate:

1. Restore node_modules/@deepseek-ai/dsh-client-ui-workspace/lib/client.js to the official release (drops the embedded ArchivedSessionsSection registration; the host patches may stay — the plugin detects them and no-ops).
2. Install and restart this plugin.
3. The plugin stands down automatically when the same section id already exists; once the in-box patch is removed the plugin takes over.

To move the host side back to stock as well, back up ~/.dsh first, reverse patches/, and let this plugin's host half re-add the backend. Trash data and the archive set are unaffected.

Data safety

• Deleting a session moves it to ~/.dsh/trash/<sessionId>-<timestamp>/, restorable at any time.
• Delete permanently / Empty trash are irreversible — both are guarded by a confirmation modal.
• Attachments are content-addressed and shared; deleting a session never deletes attachments.
• Live sessions cannot be deleted (session-live); the UI explains what to do.

Compatibility

• Target DSH: 0.1.0-rc.5 and later — both the native Web UI (dsh web in a browser) and the desktop GUI (Electron window), which share the same host services and client bundle.
• Stock hosts (rc.5 unpatched, rc.6): the host half adds the trash layer and the registry API at runtime; the client falls back to /dsh-archive/session.
• Hosts that already carry the feature — rc.5 with the in-box patches, and rc.7+ where upstream merged the same backend (persistence trash layer, registry unarchiveSession/deleteSession/ trash*, API-proxy routes, client-runtime methods): every step feature-detects and no-ops; the client calls the native ctx.workspaces API directly. Service availability is checked per call, so a service that is provided late (rc.7 gates the registry behind an inject) is picked up automatically instead of stranding the section on the fallback path.
• deleteSession is fail-closed: it refuses to run unless the persistence layer is trash-aware, so the plugin can never drive a stock hard-delete backend (nothing is removed on refusal).
• Host half shape-guards every patch; unrecognized services are skipped with a log line, never fatal.
• Cordis 4 strict inject (0.2.1): DSH Desktop ships @deepseek-ai/cordis 4.x, where reading a service property off a context (ctx.sessionPersistence) is only allowed when the current fiber declares it in inject; undeclared reads throw cannot get property "X" without inject. The host half resolves services through ctx.get(...) and through the patched methods' receiver (this.ctx, which Cordis shadows to the registry's own fiber) — never through registry.ctx on a traceable service wrapper, whose ctx property resolves to the caller's context. On older Cordis 3.x hosts both spellings work; the 0.2.1 path is required on Cordis 4.
• Dual-store client resync (0.2.2): after a fallback-path delete, the client refreshes BOTH the workspaces and the sessions stores. 0.2.0/0.2.1 only refreshed the workspaces view, so the deleted session stayed in the stale sessions list while dropping out of every workspace — the sidebar then rendered it in the Ungrouped bucket (visible until the next full reload).
• Platform: Windows / macOS / Linux (trash is plain Node fs; no platform assumptions).

Development

npm install                                # fetches the @deepseek-ai/cordis devDependency
node scripts/host-logic-test.mjs        # host lifecycle: delete → trash → restore → purge → empty → live refusal
node scripts/host-robustness-test.mjs   # late service provision + fail-closed delete + route on-demand ensure
node scripts/cordis4-strict-test.mjs    # REAL Cordis 4 strict-inject regression (0.2.1: "without inject" fix)
node scripts/eval-check.mjs             # client bundle factory eval + apply + slot registration + late-service detection + dual-store resync (0.2.2)
