RAG with Local Corpus +All answers are grounded exclusively in the `data/` folder. No external APIs or LLMs are called during triage. This ensures: +- **No hallucination** — responses can only contain what the corpus says. +- **Offline operation** — works without internet access. +- **Auditability** — every response cites its source document. + +### 2. Sentence-Transformers (all-MiniLM-L6-v2) +Chosen for: +- Small footprint (~80 MB), runs on CPU. +- Strong semantic similarity for English support text. +- Produces L2-normalised embeddings so cosine similarity = dot product (fast). + +### 3. Hybrid Classification (Keyword + Semantic) +- **Keyword voting** is fast and fully explainable. +- **Semantic fallback** handles edge cases where no keyword fires or there's a tie. +- Both stages are deterministic (seeds fixed). + +### 4. Escalation-First Policy +The decision engine follows the principle: *"when in doubt, escalate."* +Concretely: +- Any risk keyword match → immediate escalation, skipping retrieval. +- Any retrieval score below the threshold (`0.30`) → escalation. +- Three or more distinct product areas detected → escalation (complexity). + +### 5. Overlapping Chunk Retrieval +Documents are split into 300-word chunks with a 50-word overlap. This prevents useful context from being cut mid-sentence at chunk boundaries. + +### 6. Confidence Threshold +Set to `0.30` cosine similarity. Below this, retrieved documents are not sufficiently related to justify a response. This is conservative by design — false escalations are cheaper than incorrect answers. + +### 7. Determinism +`PYTHONHASHSEED`, `numpy`, `random`, and `torch` seeds are all pinned to `42` at startup, ensuring identical outputs across runs for the same input. + +--- + +## Escalation Categories + +| Risk Category | Escalated To | +|--------------------|----------------------------------| +| fraud_security | Security and Trust team | +| payment_dispute | Finance and Billing team | +| score_manipulation | Policy and Compliance team | +| account_permission | Account Management team | +| vulnerability | Security Engineering team | +| data_privacy | Privacy and Compliance team | + +--- + +## Extending the Corpus + +Add new `.txt` files to the `data/` folder — they are automatically picked up on the next run.
