Welcome to the Citadel Project — a completely independent, non-commercial private knowledge base and localized hosting ecosystem. This platform was engineered from the ground up to serve as a secure node for high-performance configuration management, network stack debugging, and server infrastructure deployment. ### Project Philosophy Unlike modern resource-heavy and censored cloud platforms, this portal operates under a strict self-hosted paradigm. The core infrastructure runs entirely on specialized, optimized localized hardware, eliminating external telemetry, vendor lock-in, and arbitrary third-party restrictions. ### System Infrastructure Overview The current environment is backed by a highly optimized, custom-tailored Unix architecture designed for maximum performance, maximum uptime, and structural isolation: * **Web Stack Core:** High-performance Nginx reverse-proxy front-end paired with an optimized PHP-FPM engine driving the Joomla 6 runtime context. * **Database Management:** Low-latency MySQL/MariaDB relational storage architecture with strictly verified indexing and enterprise-grade schema mapping. * **Network & Routing Matrix:** Low-level configuration managed directly via native Netplan routing descriptors, strict IP-filtering, and localized infrastructure firewalling policies. This node is dedicated exclusively to the preservation of verified server manuals, configuration blueprints, and battle-tested administration scripts.
