SSH into 134.199.153.159 and update all stale agent configs to match the current OpenClaw version format (2026.3.7).

For each of these agents: susan, harper, sentinel, radar, cog
1. Back up their current config: cp /root/.openclaw-{agent}/clawdbot.json /root/.openclaw-{agent}/clawdbot.json.bak-2026-03-12
2. Update the config version field to match 2026.3.7 format
3. Verify the model assignment matches what's in rivet/memory/multi-model-fleet-plan.md
4. Restart the service: systemctl restart clawdbot-{agent}
5. Check it came back: systemctl is-active clawdbot-{agent}

For herald (on 2026.3.2 — close but not current):
Same process but lower priority.

Also check: Is Builder intentionally on deepseek/deepseek-chat? The vault says Claude Opus 4.6 via LocalCC. If the config was changed, update vault/02-Fleet/Builder.md to match reality.

After all updates, run the full status check again and report what changed.

IMPORTANT: Back up every config before touching it. Do NOT change model assignments — only update the config version/format to be compatible with 2026.3.7. If the config format changed between versions, check the OpenClaw changelog first.
