In the fast‑moving world of SaaS, security questionnaires have become a gate‑keeper for every new contract. Teams spend countless hours copying policy excerpts, tweaking language, and double‑checking references. The result is a costly bottleneck that slows sales cycles and drains engineering resources.  

What if a system could read your policy repository, understand the intent behind each control, and then write a polished, audit‑ready response that feels human‑crafted yet is fully traceable to source documents? This is the promise of a **Contextual AI Narrative Engine (CANE)** – a layer that sits on top of a large language model, enriches raw data with situational context, and emits narrative answers that meet compliance reviewers’ expectations.

Below we explore the core concepts, architecture, and practical steps to implement CANE inside the Procurize platform. The goal is to give product managers, compliance officers, and engineering leads a clear roadmap for turning static policy text into living, context‑aware questionnaire answers.

## Why Narrative Matters More Than Bullet Points  

Most existing automation tools treat questionnaire items as a simple key‑value lookup. They locate a clause that matches the question and paste it verbatim. While fast, this approach often fails to address three critical reviewer concerns:

1. **Evidence of Application** – reviewers want to see *how* a control is applied in the specific product environment, not just a generic policy statement.  
2. **Risk Alignment** – the answer should reflect the current risk posture, acknowledging any mitigations or residual risks.  
3. **Clarity & Consistency** – a mixture of corporate legal language and technical jargon creates confusion; a unified narrative streamlines understanding.

CANE solves these gaps by weaving together policy excerpts, recent audit findings, and real‑time risk metrics into coherent prose. The output reads like a concise executive summary, complete with citations that can be traced back to the original artifact.

## Architectural Overview  

The following Mermaid diagram illustrates the end‑to‑end data flow of a contextual narrative engine built on top of Procurize’s existing questionnaire hub.

```mermaid

    B --> C["Semantic intent extractor"]

    F --> G["LLM narrative generator"]
    G --> H["Answer validation layer"]
    H --> I["Auditable response package"]
    I --> J["Deliver to requester"]
```  

*Each node represents a micro‑service that can be scaled independently. The arrows denote data dependencies rather than strict sequential execution; many steps run in parallel to keep latency low.*

## Building the Policy Knowledge Graph  

A robust knowledge graph is the foundation of any contextual answer engine. It connects policy clauses, control mappings, and evidence artifacts in a way that the LLM can query efficiently.

1. **Ingest Documents** – feed [SOC 2](https://secureframe.com/hub/soc-2/what-is-soc-2), [ISO 27001](https://www.iso.org/standard/27001), [GDPR](https://gdpr.eu/), and internal policy PDFs into a document parser.  
2. **Extract Entities** – use named‑entity recognition to capture control identifiers, responsible owners, and related assets.  
3. **Create Relationships** – link each control to its evidence artifacts (e.g., scan reports, configuration snapshots) and to the product components they protect.  
4. **Version Tagging** – attach a semantic version to every node so that later changes can be audited.  

When a question like “Describe your data encryption at rest” arrives, the intent extractor maps it to the “Encryption‑At‑Rest” node, retrieves the latest configuration evidence, and passes both to the contextual enricher.

## Real‑Time Risk Telemetry  

Static policy text does not reflect the current risk landscape. CANE incorporates live telemetry from:

- **Vulnerability scanners** (e.g., CVE counts by asset)  
- **Configuration compliance agents** (e.g., drift detection)  
- **Incident response logs** (e.g., recent security events)  

The telemetry collector aggregates these signals and normalizes them into a risk score matrix. The matrix is then used by the contextual data enricher to adjust the tone of the narrative:

- Low risk → emphasize “strong controls and continuous monitoring.”  
- Elevated risk → acknowledge “ongoing remediation efforts” and cite mitigation timelines.

---  

## The Contextual Data Enricher  

This component merges three data streams:

| Stream | Purpose |
|--------|---------|
| Policy excerpt | Provides the formal control language. |
| Evidence snapshot | Supplies concrete artifacts that back the claim. |
| Risk score | Guides the narrative tone and risk language. |

The enricher formats the merged data as a structured JSON payload that the LLM can consume directly, reducing hallucination risk.

```json
{
  "control_id": "ENCR-AT-REST",
  "policy_text": "All customer data at rest must be protected using AES‑256 encryption.",
  "evidence_refs": [
    "S3‑Encryption‑Report‑2025‑10.pdf",
    "RDS‑Encryption‑Config‑2025‑09.json"
  ],
  "risk_context": {
    "severity": "low",
    "recent_findings": []
  }
}
```

---  

## LLM Narrative Generator  

The heart of CANE is a fine‑tuned large language model that has been exposed to compliance‑style writing. Prompt engineering follows a **template‑first** philosophy:

```
You are a compliance writer. Using the supplied policy excerpt, evidence references, and risk context, craft a concise answer to the following questionnaire item. Cite each reference in parentheses.
```

The model then receives the JSON payload and the questionnaire text. Because the prompt explicitly asks for citations, the generated answer includes inline references that map back to the knowledge graph nodes.

**Example output**

> All customer data at rest is protected using AES‑256 encryption (see S3‑Encryption‑Report‑2025‑10.pdf and RDS‑Encryption‑Config‑2025‑09.json). Our encryption implementation is continuously validated by automated compliance checks, resulting in a low data‑at‑rest risk rating.

---  

## Answer Validation Layer  

Even the best‑trained model can produce subtle inaccuracies. The validation layer performs three checks:

1. **Citation integrity** – ensure every cited document exists in the repository and is the latest version.  
2. **Policy alignment** – verify that the generated prose does not contradict the source policy text.  
3. **Risk consistency** – cross‑check the stated risk level against the telemetry matrix.  

If any check fails, the system flags the answer for human review, creating a feedback loop that improves future model performance.

---  

## Auditable Response Package  

Compliance auditors often request the full evidence trail. CANE bundles the narrative answer with:

- The raw JSON payload used for generation.  
- Links to all referenced evidence files.  
- A changelog showing the policy version and risk telemetry snapshot timestamps.  

This package is stored in Procurize’s immutable ledger, providing a tamper‑evident record that can be presented during audits.

| **0 – Foundation** | Deploy document parser, build initial knowledge graph, set up telemetry pipelines. |
| **1 – Enricher** | Implement JSON payload builder, integrate risk matrix, create validation micro‑service. |
| **2 – Model Fine‑Tuning** | Collect a seed set of 1 000 questionnaire‑answer pairs, fine‑tune a base LLM, define prompt templates. |
| **3 – Validation & Feedback** | Roll out answer validation, establish human‑in‑the‑loop review UI, capture correction data. |
| **4 – Production** | Enable auto‑generation for low‑risk questionnaires, monitor latency, continuously retrain model with new correction data. |
| **5 – Expansion** | Add multilingual support, integrate with CI/CD compliance checks, expose API for third‑party tools. |

Each phase should be measured against key performance indicators such as **average answer generation time**, **human review reduction percentage**, and **audit pass rate**.
