Domain Driven Centric Router (DDCR) — A Deterministic Runtime Semantic Resolution Engine

Domain Driven Centric Router (DDCR) — A Deterministic Runtime Semantic Resolution Engine DDCR defines a deterministic, seven-stage runtime semantic resolution engine designed for programmable API Gateway environments. The engine executes a fixed semantic resolution pipeline within the Target Endpoint PreFlow, decoupling semantic façade addressability from backend infrastructure topology. DDCR resolves structured semantic URLs following the canonical pattern: /domain/entity/action/target The engine is domain-agnostic and infrastructure-independent. Any named semantic hierarchy — including business domains, product platforms, identity systems, IoT environments, media services, or organizational contexts — can be resolved using the same deterministic resolution model. Routing intelligence resides entirely within the runtime engine. The metadata store acts as a passive control plane containing human-governed routing entries, while the engine performs semantic normalization, validation, key composition, metadata resolution, and dynamic backend binding. The deterministic seven-stage pipeline guarantees: semantic normalization across heterogeneous action vocabularies whitelist-based routing validation proxy immutability and metadata-driven extensibility deterministic runtime resolution independent of gateway vendor DDCR has been validated under production-equivalent load conditions: 1, 500, 000 requests processed Zero routing failures 99. 99% availability Sub-4 ms routing latency Validation was conducted across multiple programmable API Gateway platforms, including: SAP BTP API Management AWS API Gateway Microsoft Azure API Management Kong Gateway The JavaScript reference implementation, Phantom v12, constitutes the authoritative production implementation of the DDCR runtime engine. Equivalent implementations have been validated in C#, Python, and Lua, demonstrating language and platform independence. DDCR establishes a deterministic Layer-7 semantic resolution model for enterprise API governance, enabling metadata-driven routing architectures independent of gateway vendor or domain semantics.
