Abstract

VORTEXRAG is a novel 7-layer Retrieval-Augmented Generation (RAG) framework that simultaneously solves the two fundamental failure modes that have limited RAG systems since their inception: Semantic Drift and Context Window Poisoning. Why existing RAG systems fail Standard RAG systems fail because dense retrieval cannot distinguish between a chunk that caused an event and a chunk that was merely associated with it. Query: "Why did Lehman Brothers collapse? " Standard cosine similarity retrieves Dodd-Frank Act provisions (similarity 0. 87) alongside the actual CDS mispricing mechanism (similarity 0. 91). The LLM sees both and hallucinates a policy-response narrative instead of the causal mechanism. This is Semantic Drift. Even when the correct chunk is retrieved, 7 surrounding irrelevant chunks dilute the LLM's attention window — Context Window Poisoning. The VORTEXRAG 7-Layer Solution TVE — Tri-Vector Encoding: Encodes each text into a 864-dimensional tri-vector combining semantic (768d SBERT all-mpnet-base-v2), syntactic (64d spaCy dependency), and causal (32d PropBank) arms. Score = α·cosₛem + β·cosₛyn + γ·coscau. VRC — Vortex Retrieval Cone: Models retrieval as a spiral probability surface. Spiral rank = TVE · e^ (−λr) · cos (nθ). Chunks causally misaligned by θ > π/4 are geometrically suppressed regardless of semantic similarity. SDC — Semantic Drift Corrector: Computes a causal drift vector D = vcau (q) − vcau (c) and scores SDS = 1 − tanh (‖D‖/τ). Only chunks with SDS ≥ 0. 72 pass. Domain-tuned τ from 0. 30 (medical) to 1. 20 (creative). CPG — Context Poison Guard: Measures the Effective Signal Ratio ESR = Σ SDS·w / (P+ε) of the entire window. Greedy purge removes minimum-SDS chunks until ESR ≥ 3. 5. Theorem 5. 1 proves greedy optimality. RFG — Rank Fusion Gate: Multiplicative Φ-score: Φ = TVE^α × SDS^β × ESRcontrib^γ. Multiplicative fusion enforces a no-weak-link policy — no chunk advances unless strong on all three dimensions. CCB — Causal Context Builder: Constructs a causal dependency graph and assigns slot positions pos = rank (Φ+) × causaldepth. Depth-0 root-cause chunks are placed at position 0 to exploit the empirically established U-shaped LLM recall curve. FV — Faithfulness Verifier: Post-generation gate ΔR = 1 − ROUGE-L × NLI. Accepts if ΔR ≤ 0. 15. Up to 3 retries with reranked context. Uses DeBERTa-v3-small CrossEncoder. Benchmark Results Exact Match (EM): 74. 8 — vs Naive RAG: 61. 2 (+13. 6), CRAG: 66. 9 (+7. 9), Self-RAG: 68. 4 (+6. 4) F1: 82. 6 — highest across all 8 evaluated systems Faithfulness: 0. 94 — +0. 23 over Naive RAG, +0. 13 over Self-RAG Semantic Drift Rate: 14% — reduced 61% from Naive RAG baseline Context Poisoning Rate: 7% — reduced 71% Latency: 185ms — 2. 2× faster than Self-RAG (410ms) Ablation Study (A→H) A (61. 2 EM) → +TVE (65. 3, +4. 1) → +VRC (67. 8, +2. 5) → +SDC (70. 4, +2. 6) → +CPG (72. 1, +1. 7) → +RFG (73. 4, +1. 3) → +CCB (73. 9, +0. 5) → +FV (74. 8, +0. 9) 11 Domain Presets Pre-calibrated parameter vectors (α, β, γ, τ, θCPG, δSDC, δFV) for: scientific (τ=0. 30), medical (τ=0. 35), legal (τ=0. 40), cybersecurity (τ=0. 45), financial (τ=0. 50), code (τ=0. 60), educational (τ=0. 65), general (τ=0. 80), historical (τ=0. 90), customer support (τ=0. 95), creative (τ=1. 20).
