System Diagrams

This document provides high-level and detailed visual representations of the GrantMaster architecture using Mermaid.js.

1. System Landscape (Level 1 C4 Model)

Shows how users and external systems interact with the GrantMaster platform.

2. EventBus Flow (Fan-Out Pattern)

How a single user action (e.g., claiming a grant) triggers multiple background processes.

3. Grant Pursuit State Machine

The lifecycle of a grant within the platform.

4. Security Layer (The “Onion” Model)

Our defense-in-depth strategy.

5. AI Knowledge Graph (RAG Flow)

How we inject context into LLM prompts for high-quality grant drafting.

6. Component Hierarchy (Backend)

How our core service logic is organized for reusability.

7. Authentication Sequence

8. Subscription Upgrade Loop
