From c52dbdb8f161254a7cfe1e36be11165a1442f272 Mon Sep 17 00:00:00 2001 From: Benjamin Admin Date: Sat, 21 Mar 2026 11:49:43 +0100 Subject: [PATCH] =?UTF-8?q?feat(rag):=20optimize=20RAG=20pipeline=20?= =?UTF-8?q?=E2=80=94=20JSON-Mode,=20CoT,=20Hybrid=20Search,=20Re-Ranking,?= =?UTF-8?q?=20Cross-Reg=20Dedup,=20chunk=201024?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1 (LLM Quality): - Add format=json to all Ollama payloads (obligation_extractor, control_generator, citation_backfill) - Add Chain-of-Thought analysis steps to Pass 0a/0b system prompts Phase 2 (Retrieval Quality): - Hybrid search via Qdrant Query API with RRF fusion + automatic text index (legal_rag.go) - Fallback to dense-only search if Query API unavailable - Cross-encoder re-ranking with BGE Reranker v2 (RERANK_ENABLED=false by default) - CPU-only PyTorch dependency to keep Docker image small Phase 3 (Data Layer): - Cross-regulation dedup pass (threshold 0.95) links controls across regulations - DedupResult.link_type field distinguishes dedup_merge vs cross_regulation - Chunk size defaults updated 512/50 → 1024/128 for new ingestions only - Existing collections and controls are NOT affected Co-Authored-By: Claude Opus 4.6 --- .../ingest-industry-compliance.test.ts | 8 +- ai-compliance-sdk/internal/ucca/legal_rag.go | 244 +++++-
