dsh-archive-manager

The DSH archive-session action only hides a session from the grouped views. The underlying session.jsonl.zstd log, workspace accounting entries, and projection cache all remain on disk untouched, while the official UI offers no delete entry at all. As archived sessions accumulate over time, disk space silently fills up with no built-in way to reclaim it.

This plugin adds an Archive Manager tab to the Settings page, peering alongside General and Models. It lists every archived session with its title, creation time, and whether the log file still exists on disk. Each row carries a Delete button gated by a confirmation dialog; on confirm, the plugin removes the session log, clears the archived ID from workspace.json, strips the session ID from every workspace sessionIds array, and purges the entry from session_projcache.json. The cost ledger (ledger.json) is deliberately left intact so spend history is preserved. Security is handled with same-origin POST only, strict session-id format validation, Node self-verification after every write, and automatic rollback on failure.

Ideal for users who have collected dozens or hundreds of archived sessions and want a verified, disk-level cleanup without manually hunting through file trees. A few clicks in Settings and the session is gone for real.
