Archived Session Management

Implement archived-session UX as an end-to-end feature, not a single-button patch. Archived session work spans the Control UI, gateway RPC handlers, transcript file moves, the session_history SQLite index, and the live sessions.json store.

Core workflow

1. Inspect the whole chain first

   • UI list/search rendering
   • gateway methods for sessions.archived, sessions.resume, sessions.deleteArchived
   • archive/restore helpers in src/gateway/session-archive.ts
   • history DB filters in src/config/sessions/history-db.ts
   • live session store behavior in sessions.json

2. Treat these as separate failure classes

   • archived list cannot find a real session
   • archived list finds the session but resume fails
   • resume works but opens the wrong live session
   • session vanishes from both Live and Archived due to DB/store drift
