	## 🎯 Problem Statement

	Investigative agencies and forensic departments face critical challenges:

	- Volume overload: Processing large amounts of forensic/digital evidence within limited time
	- Manual bottlenecks: Autopsy reports, CCTV logs, mobile metadata analyzed separately by different teams
	- Missed connections: Cross-evidence correlations invisible to siloed manual analysis
	- Delayed triage: Critical leads buried under routine cases due to lack of intelligent prioritization
	- No standardization: Each investigator approaches evidence differently, creating inconsistency

	ForensiX AI solves this by providing an AI-powered unified platform that:
	1. Automatically extracts structured data from unstructured forensic reports
	2. Correlates physical evidence with digital traces in real-time
	3. Identifies anomalies and generates investigative leads
	4. Provides explainable risk scoring for case prioritization
	5. Operates with full chain-of-custody integrity (SHA-256 ledger)

	## 💡 Novelties & Innovation

	### 1. Digital Stratigraphy
	Unlike existing forensic systems that separately analyze pathology reports OR digital evidence, ForensiX introduces a unified multimodal architecture that semantically correlates ALL evidence types into synchronized investigative layers.

	### 2. Zero-Shot Forensic NER
	Using GLiNER-biomed, investigators can define ANY custom entity type at runtime using natural language — no model retraining needed. Want to detect "ligature material type"? Just add it to the label list.

	### 3. GraphRAG-Enhanced AI Chat
	Every AI response is grounded in verified forensic knowledge retrieved via semantic search. The LLM cannot hallucinate forensic facts because the system prompt is injected with authoritative knowledge nodes.

	### 4. Cross-Case Serial Pattern Detection
	Automated matching against historical case database identifies potential serial offenders by comparing MO patterns, weapon types, victim profiles, and behavioral signatures.

	### 5. Explainable Risk Scoring
	Every risk score is decomposable into SHAP-style attributions. Investigators can see EXACTLY which evidence drives the score — legally defensible transparency.

	### 6. Universal LLM Provider
	Works with ANY provider (12+ supported). Investigators aren't locked into one AI vendor. Seamless fallback chain ensures the system never goes dark.

	### 7. Offline-Capable Custom Models
	Fine-tuned models run entirely on CPU without internet. Critical for sensitive investigations where data cannot leave the network.

	---

	## ⚖️ Ethical Considerations

	- Advisory only: All outputs support human decision-making, never replace forensic experts
	- No legal conclusions: System uses "suggests", "indicates", "consistent with" — never "proves"
	- Explainable: Every AI output traceable to specific evidence (SHAP attribution)
	- Chain of custody: SHA-256 immutable ledger ensures evidence integrity
	- Data privacy: Local-first architecture, cloud optional, no mandatory data sharing
	- Bias awareness: Models trained on balanced synthetic data to avoid demographic bias
	- Access control: JWT authentication, role-based permissions

	## 📊 Performance Metrics

	\| Metric \| Value \|
	\|--------\|-------\|
	\| API Endpoints \| 55+ routes, all verified 200 OK \|
	\| Multi-Agent Analysis \| 7 agents, ~16s total (with LLM) \|
	\| NLP Entity Extraction \| <100ms per report (regex) \|
	\| Risk Scoring \| <50ms computation \|
	\| Graph Building \| <200ms for full evidence graph \|
	\| WebSocket Latency \| <50ms real-time updates \|
	\| Local ML Inference \| <500ms (NER), <100ms (classifier) \|
	\| Knowledge Retrieval \| <10ms (keyword), <200ms (semantic) \|

	## 🛡️ Security

	- Authentication: JWT (HS256) with configurable secret
	- Evidence Integrity: SHA-256 hash chain (blockchain-style)
	- Data Isolation: SQLite per-instance, no shared state
	- API Security: CORS configured, rate limiting available
	- Sensitive Data: All LLM calls use local context — no case data sent to external APIs unless investigator explicitly uses AI Chat
