search_plans()to check if past context already covers this - If oracle active: include any tool discoveries in
key_insights praetorian_compact(type, title, key_insights, refs)- If vigil active: files are also checkpointed via quicksave
Restore (standalone)
praetorian_restore()— list recent compactionspraetorian_restore("query")— search for specific topic- Summarize findings for the current task
Restore (with siblings)
