It is designed to bypass standard bootstrap phases and rapidly forge hardened, ultra-optimized workspace environments for Xeon-based "swarm" nodes and high-security virtualization targets. -Namespace: DCOSNET -Overview +This project treats the build process as a forensic exercise. It does not simply compile code; it instantiates a sovereign environment, stamps the resulting binaries with a "Silicon Birth Certificate," and continuously monitors the forge's health via an internal thermal and entropy sentinel. -BTC (Build Tool Chain) is a bare-metal, cleanroom toolchain generation engine engineered to bypass initial bootstrapping phases and rapidly build hardened, ultra-optimized workspace environments for Xeon-based "swarm" nodes. +### Key Architectural Pillars +* **Sovereign Forge:** Built to LFS 13.0 stable standards (Binutils 2.46, GCC 15.2, Glibc 2.43). +* **Silicon Identity:** Every binary produced includes an immutable ELF note (`.note.BTC`) and extended filesystem attributes (`xattr`) linking the binary to the specific hardware and forge environment that created it. +* **Hardened Profiles:** Profile-driven kernel injection (`ghost` for monolithic/static systems, `virt` for hypervisor guests). +* **Zero-Trust Deployment:** Mandatory AGPLv3 licensing protects the toolchain logic from proprietary SaaS capture, ensuring the forge remains open-source regardless of how it is deployed. -This project was originally based on the buildchain.sh script by Charles M. "Chip" Coldwell, though it has been heavily modified to support contemporary build requirements and sovereign forensic auditing. -Architectural Notes: Picking Your Target +### Technical Forge Features +* **Volatile Cleanroom:** All compilation occurs in a volatile ramfs mount, ensuring zero I/O wear on host hardware and providing a "pristine-every-time" build environment. +* **The Invisible Guard:** Integrated telemetry loops prevent thermal runaway and memory saturation during heavy LTO (Link Time Optimization) phases. +* **Forensic Auditing:** Every build creates a verifiable manifest, allowing you to trace any binary back to the exact git commit and forge state that spawned it. -If you are determining your target architecture, first identify your device's specific processor architecture and the corresponding naming convention used by your kernel. +### Licensing +This project is licensed under the **GNU Affero General Public License v3 (AGPLv3)**. +- *Note:* Per Section 13, this forge includes an interactive notice at runtime.

These are preferred when a full development environment is required and storage space for a large rootfs is available. - - ARM / MIPS / RISC / Others: Typically utilize uclibc and busybox. These are preferred for environments with limited disk space, though modern ARM implementations are increasingly capable of supporting larger rootfs configurations. - -Key Architectural Features - - Speed-of-Light Volatile Compilation: Automatically provisions 50% of available physical RAM into a high-speed ramfs mount (/usr/src) to eliminate disk I/O bottlenecks. - - Silicon-Bounded Optimization: Dynamically interrogates the host CPU to target native microarchitectures (bdw/hsw). - - Forensic Stamping: Injects a permanent, immutable ELF note (.note.BTC) and filesystem xattrs into all compiled binaries to serve as a "Silicon Birth Certificate." - - The Invisible Guard: Continuous background telemetry prevents thermal runaway (throttling above 85°C) and mitigates out-of-memory (OOM) faults. - -1.
