+# Next Steps - 2026-03-17
+
+## High Priority
+- [ ] Monitor system behavior under multi-day sustained load to ensure `zswap` and `MGLRU` keep the system responsive.
+- [ ] Verify that `archlinux-keyring-wkd-sync.service` failure is resolved or investigate further (currently noted in health report).
+
+## Optimization
+- [ ] Evaluate if `systemd-oomd` is aggressive enough for interactive desktop use; if not, consider testing `earlyoom` as an alternative.
+- [ ] Automate periodic S.M.A.R.T. checks via a systemd timer (currently manual).
+
+## Infrastructure
+- [ ] Consolidate Ansible variables for Docker memory limits into `ansible/vars/main.yml`.
+- [ ] Extend `scripts/maintenance.sh` to include a summary of the last 24h OOM events (if any).
