⚠️ Reading Order — Start with GDCR. GDCR (DOI: 10.5281/zenodo.18582492) is the foundation of the entire ecosystem. Begin there — every other layer (DDCR, ODCP, SDIA, DEIP) builds on top of it. Without GDCR, the full picture will be incomplete. DEIP — Domain Enterprise Integration Pattern — is a domain-centric architectural meta-framework that introduces a semantic control plane for enterprise integration governance. It decouples business intent from protocol and platform selection through a formal six-stage decision pipeline: Intent → Interaction Type → Quality Profile → Integration Capability → Protocol Profile → Platform Binding DEIP addresses the six structural failure modes present in every enterprise integration landscape at scale: protocol sprawl, platform sprawl, proxy sprawl, runtime sprawl, package sprawl, and credential sprawl — through a single invariant: the domain intent is the only valid primary key for integration governance. DDCR engine — a deterministic semantic routing mechanism based on mathematical principles~2,067,904 requests · 8 platforms · 5 programming languages · 100% routing accuracy · zero routing failures · sub-4ms resolution latency.

End-to-end latency varies by platform and transcontinental path (PL→USA/DE/SG). 158 failures = network-layer only (ECONNRESET/ETIMEDOUT). Zero routing failures across all platforms. All Newman test suites were fired from Poland targeting SAP BTP infrastructure in the United States, with continuous execution windows of up to 29 hours. Under these transcontinental conditions — spanning network instability, timezone shifts, and sustained load — DDCR mathematical behavior remained completely stable. Zero routing failures. The engine does not degrade. The domain never lies. License: CC BY 4.0 — Ricardo Luz Holanda Viana — Warsaw, Poland — March 2026
