dsh-session-steward

After months of use, DSH quietly accumulates a pile of archived session files on disk. You may want to clean them out but hesitate for fear of irreversible damage, or want to restore an archive but cannot find the right entry point. This plugin adds a Session Steward panel to the sidebar so you can inspect the archived collection, its per-entry size, and the on-disk entity state before taking any action.

Two capabilities are kept deliberately separate and non-interchangeable. For session history files, unarchiving (prune) only edits the stored array and is fully reversible; purging (purge) deletes real disk entities including transcript directories, projection caches, and two workspace-membership entries, making it permanent and auto-unarchiving first to avoid leaving zombie ids that vanish from the sidebar. For session health, a four-gate check covers log integrity, projection-cache lag, lossless-JSON validity, and cold-read closure; the resulting prescription is strictly reversible: isolate corrupted projection-cache records, wait for the host to settle open steps, and emit an actionable command list with a before/after diff. The plugin never rewrites session logs or silently drops fields.

Best suited for long-term DSH users who have accumulated a large archive, occasionally hit empty-session or data-corruption issues, and want a safe diagnostic pass before any cleanup. Each sub-domain has its own feature gate so you can enable or disable them independently without affecting the other.
