End-to-End Pipeline Architecture for Evidence-Graded Knowledge Graphs: From Source Ingestion to Weighted Edge Delivery

Paper 6 in the Prioris research series. Describes the complete Prioris pipeline architecture: three-channel ingestion (253 RSS, 11 API, 7 Playwright), two-layer deduplication, fact/observation/inference extraction, confidence calibration, and composite weighting. Covers 271 source definitions across 25 domains, PostgreSQL+pgvector data model, staleness monitoring, and Docker-based reproducible deployment. Systems paper — architecture description, not empirical benchmark. Part of the research programme (Paper 0: 10.5281/zenodo.19024611).
