+Check the currently deployed version on production.
+
+Run this SSH command to get the image digests and match them to git SHAs:
+
+```bash
+ssh -i ~/.ssh/trails-cool-deploy root@91.99.14.111 "docker compose -f /opt/trails-cool/docker-compose.yml images" 2>&1
+```
+
+Then compare with the latest CD run:
+
+```bash
+gh run list --workflow cd.yml --limit 1 --json headSha,conclusion,status -q '.[0]'
+```
+
+Show:
+- Which images are running (journal, planner, brouter, postgres, caddy)
+- The git SHA they were built from (matches the image tag)
+- Whether the latest CD run matches what's deployed
+- Quick health check: curl both https://trails.cool and https://planner.trails.cool
