+## Intro
+
+Why I’m sharing this story
+
+A quick disclaimer: not everything went smoothly
+
+## The Calm Before the Storm
+
+My OPNsense setup before the incident
+
+Confidence in my homelab
+
+## The Unexpected Reboot
+
+How I first noticed something was wrong
+
+The kernel panic that started it all
+
+## First Troubleshooting Attempts
+
+Caddy refusing to start
+
+Digging into logs and finding corrupted certs
+
+Quick fixes to restore services
+
+## Filesystem Corruption
+
+Upgrade attempt from 25.1 to 25.7 gone wrong
+
+pkg errors and a broken package database
+
+Discovering the dirty filesystem with fsck
+
+## When Things Got Worse
+
+Broken bootstrap and missing core components
+
+Realizing the system was half-upgraded and unstable
+
+The tough decision: reinstall vs. repair
+
+## Starting Over the Hard Way
+
+Pulling the box out of the rack
+
+Preparing the installer USB
+
+Fresh install of OPNsense 25.7
+
+## The Lifesaver: config.xml
+
+Copying my configuration from backup
+
+Restoring the system to its former self
+
+Which services came back instantly
+
+Which ones didn’t (goodbye UniFi controller backup…)
+
+## Lessons Learned the Hard Way
+
+What I did wrong (and why it hurt)
+
+What I should have done differently
+
+The single most important file in OPNsense
+
+Why keeping off-box backups matters
+
+## Moving Forward
+
+My new backup strategy
+
+Plans to improve reliability in my homelab
+
+Final thoughts: sometimes starting fresh is the cleanest fix
+
+## Conclusion
+
+How this failure taught me more than a normal upgrade ever could
+
+Encouragement for others to prepare before disaster strikes
