# Nginx Permission Pitfall — Prevention Checklist
The #1 recurring bug in ShopProQuote development. Every new file created by
agents or build tools defaults to owner-only permissions (600). Nginx runs as
`www-data` and returns 403 Forbidden. When a JS module returns 403, every file
that imports it silently fails — no console error, just dead features.
## After creating ANY new file in the project
```bash
# Fix all 600-permission files in one command
find /mnt/seagate8tb/Websites/ShopProQuote -name "*.js" -perm 600 -exec chmod 644 {} \;
find /mnt/seagate8tb/Websites/ShopProQuote -name "*.css" -perm 600 -exec chmod 644 {} \;
```
## Diagnostic when pages are broken but HTML loads fine
```bash
# Check all JS files are accessible
for f in shared/debug.js shared/skeleton.js api.js dashboard.js repair-orders.js; do
curl -sk -o /dev/null -w "%{http_code} " https://localhost/$f && echo "$f"
done
# Check nginx error log for permission denied
tail -50 /var/log/nginx/error.log | grep -i "permission denied"
```
## Files that have been broken by this bug (historical)
| File | Symptom when 403 |
|------|-----------------|
| `shared/debug.js` | ALL modules that import it silently fail. Entire app dead. |
| `shared/skeleton.js` | Skeleton loading functions unavailable, graceful fallback to text |
| `dist/custom.css` | No custom styling — site looks completely unstyled |
| `dist/tailwind.css` | No Tailwind — site looks like plain HTML |
## Worker/agent file creation checklist
After `write_file`, `patch`, or terminal commands that create files:
1. `ls -la <file>` — check permissions
2. If `-rw-------` (600), `chmod 644 <file>`
3. `curl -sk -o /dev/null -w "%{http_code}" https://localhost/<file>` — verify accessible
