"Architecture is the art of planning for the unknown. We don't just build code; we build sovereign digital assets designed to outlast the tools."

STIE is engineered for Mission-Critical Environments where logic must govern prediction. We apply the Sovereign Protocol to ensure:
- The Supreme Verdict: The ML model acts as a "Consultant." The Sovereign Core acts as the "Judge." If a prediction violates physical reality (e.g., Velocity > 125 mph), the Core enforces the safe limit.
- Physical Invariants: We don't just validate data; we enforce the laws of physics and urban mobility through Atomic Defense.
- Architectural Longevity: By isolating logic from "Interchangeable Tools," the system remains a permanent asset that outlasts the tools.
STIE is a Future-Proof engineered Unified Inference Hub. In this architecture, the Business Logic is the Sovereign Power. The core is a Sovereign Sanctuary (Domain Core) with zero external dependencies. All external tools (Cloud providers, ML Engines) are merely "Interchangeable Gears" (تروس) that serve the logic; the logic never serves them.
- The Refinery Protocol: Zero-tolerance for data noise. We treat data as unrefined ore; only "Sanctified" records reach the BigQuery sink.
- Economic Optimization: Powered by Polars (Lazy API), maximizing throughput while minimizing cloud costs—essential for high-scale urban deployments.
- Institutional Transparency: Adherence to the SDDL (Self-Documenting Domain Language) ensures that the engineering "Why" is never lost, making the system a transparent, audit-ready asset.
- Strict Provenance: Every entity carries its
source_id, ensuring 100% traceability from raw ingestion to final inference verdict.
- Domain Core (The Sanctuary): Zero external library imports (Standard Python 3.12+).
- Application Layer (The Orchestrator): Defines Strict Ports (Interfaces) for data ingestion and inference.
- Infrastructure Layer (The Laborers): Swappable adapters for Polars, ML engines, and Cloud APIs.
- Memory Efficiency (SOTA): Mandated
slots=Trueandfrozen=Truefor extreme RAM optimization and sub-second processing. - The Lazy Protocol: Integration of Polars Lazy API for optimized query pushdown and zero-copy ingestion.
- Sovereign Registry Pattern: Flexible
Dict[str, float]for multi-model scalability (Duration, Tip, Cancellation) within the core entity.
- Enterprise-Grade Code Quality: Managed via SonarQube for continuous monitoring of Technical Debt.
- Sovereign Error Taxonomy: Every failure returns a deterministic code (e.g.,
ERR_DOM_VAL_001). - Shield Protocol: Mandatory Pre-commit Hooks enforcing strict linting before any persistence.
- Security & Compliance: Mend (WhiteSource) integration for continuous vulnerability scanning.
- Static Guardrails: Strict Pyright static analysis to ensure 100% type-safety.
- Test & Logic Integrity: Enforced via pytest and pytest-cov for automated coverage reporting.
- Quality Suite: Advanced stress testing powered by Hypothesis (PBT) and Factory-Boy.
- Deterministic Environments: Powered by uv project (Mandatory).
- Model Provenance: MLflow integration for full experiment lineage.
