DDCR — Domain Driven-Centric Router Layer 2 of the SDIA Ecosystem — v3.0 FINAL Zenodo: 10.5281/zenodo.18864832🔗 https://zenodo.org/record/18864832 DDCR is the deterministic runtime semantic resolution engine of the SDIA ecosystem (Semantic Domain Integration Architecture). Its role is not to define gateway facade or orchestration topology, but to resolve semantic intent into backend endpoints through a fixed seven-stage pipeline, using a passive metadata control plane (KVM, Redis, DynamoDB, etc.). The engine never guesses. It resolves or fails fast. What DDCR provides: ↳ Seven-stage deterministic pipeline (extract → load → guard → normalize → build → resolve → bind)↳ Action normalization — 247 raw action variants → 15 canonical codes↳ Metadata key construction — positional, delimiter-free↳ Fail-fast whitelist enforcement — no match = HTTP 500↳ Proxy immutability — new backends = 1 metadata entry, zero redeployment Comparison with existing APIM routing models: Approach Limitation DDCR Static routing New backend = new proxy 1 metadata entry Conditional routing New backend = new IF/Else rule f(key) → value — deterministic Service discovery No semantic normalization 247 action variants → 15 codes Validated results: ~2,067,904 requests · 8 platforms · 5 languages 100% routing accuracy · zero routing failures · sub-4ms latency This is the FINAL version of DDCR. No further structural updates are planned. The seven-stage pipeline, action normalization, metadata key schema, and fail-fast invariants are complete and stable.
