-## Upgrading
-
-### From Earlier Versions
-
-If you have an **old database with sire/dam columns** or missing litter_id:
-
-```bash
-# Backup your data
-cp data/breedr.db data/breedr.db.backup
-
-# Delete old database
-rm data/breedr.db
-
-# Pull latest code
-git pull
-
-# Restart (will create clean schema)
-docker-compose restart
-```
-
-**Important:** The new schema uses a `parents` table instead of sire/dam columns. Parent data cannot be automatically migrated - you'll need to re-enter parent relationships.

 ## Troubleshooting
 
+### Server crashes with `SyntaxError: Unexpected end of input` on `settings.js`
+The settings route file may have been corrupted (double-encoded base64). Pull the latest code and rebuild.
+
+### "no such column: kennel_name" or "no such column: is_champion"
+Your database predates the `ALTER TABLE` migration guards. Pull the latest code and restart — columns are added automatically. No data loss.

-### Parent relationships not saving
-
-Check server logs for:
-```
-✔ Dog inserted with ID: 123
-  Adding sire relationship: dog 123 -> sire 5
-  ✔ Sire relationship added
-```
-
-If you don't see these logs, ensure `sire_id` and `dam_id` are being sent in the API request.
-
 ### Logo not appearing in navbar
-
 Ensure `br-logo.png` is placed in the `static/` directory at the project root. The file is served at `/static/br-logo.png`.
 
 ### Heat cycles not showing on calendar
-
 Ensure dogs are registered with `sex: 'female'` before creating heat cycles. The API validates this and will return a 400 error for male dogs.
 
 ### Whelping window not appearing on calendar
