+When a session was ended via `tmux-agent-orchestrate-stop` (which captures the ID and gracefully stops by default),
+its row is `status: stopped` with `resumable: true` and the conversation id
 already recorded in `claude_session_id_own` / `agy_conversation_id_own`. This is the
 ideal resume path:

+- **tier-1, race-free**: because the stop command wrote the id into the row at stop
   time, `resolve_session_id.sh` resolves it via `find_workspace_uuid` tier-1 (the
   per-row own id) — no reliance on the mtime-based disk scan, so a concurrent
   session in another workspace can never shadow it.
