<ol>
<li>
<p><strong>Single-file Flask app:</strong> No package structure needed — the app has 6 endpoints and one HTML template. Keeping it in one file makes deployment trivial (scp + systemctl restart).</p>
</li>
<li>
<p><strong>Caddy on Core as single entry point:</strong> app3 isn't exposed to the internet directly. All access goes through Core's Caddy with proper timeouts. The restore operation takes 30-45s and Caddy's default proxy timeout was killing connections mid-operation.</p>
</li>
<li>
<p><strong>Tar + mysqldump over rsync:</strong> Snapshots are point-in-time archives, not incremental backups. Each snapshot is self-contained (files.tar.gz + database.sql). Restore is a single operation with no dependency chain.</p>
</li>
<li>
<p><strong>No auth on backup API:</strong> The endpoints have no authentication. Access is controlled by Caddy routing — only requests through my.itpropartner.com reach the app. Internal network only.</p>
</li>
</ol>
