UniHive recommender — engine 3.0 (BGE-384), work in progress

Hybrid feed engine retrained for 384-d BAAI/bge-small-en-v1.5 embeddings, no community features, 114 interest tags, dwell/action labels, built to plug into the main backend behind PERSONALIZATION_ENGINE=hybrid.

  • hybrid_engine/ — engine, main_adapter.py (Postgres only, no Redis), aliases, tag backfill, tests; artifacts_v3/ holds the ONNX models and reports
  • main_patch/ — 4 patches for main (git am); training_scripts/ — build/verify scripts
  • ENGINE_V3.md, COMPATIBILITY_REPORT.md/.pdf — design and compatibility report
  • ENGINE_V3_OPEN_ISSUES.md — read first: what is verified and what still needs fixing

Status: tests on a real PostgreSQL pass (327 / 325), but the production image, live LLM tagger and frontend are untested, and the model has not seen real UniHive traffic.
