⚙️ Polyglot Sovereign Architecture

To achieve mathematical accuracy, direct hardware access, and extreme performance, the ecosystem operates a multi-tier sovereign engine strategy:

Tier 1 - Systems & Hardware Engines (Rust):
- DZ-DiskTree: Direct cluster allocation disk scanning in 3.08 milliseconds (215 KB standalone binary).
- DZ-Archive: Multi-threaded compression, CRC-32 verification, and multi-core CPU benchmark at 7,000+ MB/s.
- DZ-DevTools: High-speed CLI binary dz for CCP Modulo-97, RIP generation, and Luhn algorithm validation.
Tier 2 - Engineering & Media DSP Engines (Python 3.14):
- DZ-RPA: Official Algerian Seismic Code RPA 99 / Version 2003 (DTR-BC 2-48) computation engine.
- DZ-Photo: NumPy and Pillow multi-layer raster graphics engine with Algerian color grading filters.
- DZ-Player: 300% volume boost soft-limiter DSP, 10-band equalizer, and Windows-1256 Arabic subtitle repair.
Tier 3 - Enterprise Accounting & Human Resources (C# .NET 10):
- DZ-Compta: High-precision decimal accounting ledger with 100% debit/credit mathematical equilibrium.
- DZ-Paie: Official Algerian payroll calculations, CNAS 9% deductions, and progressive DGI IRG tax scaling.
