## Executive Overview
This document serves as the comprehensive reference architecture guide for an event-driven, highly available Google Cloud application.

## Functional requirements
- Accept authenticated HTTPS requests from external clients.
- Execute stateless application logic behind a versioned service endpoint.
- Asynchronously publish domain events to Pub/Sub.
- Retain raw payload records in Cloud Storage for audit and replay.

## Selected products
- **Compute**: Google Cloud Run
- **Messaging**: Google Cloud Pub/Sub
- **Storage**: Google Cloud Storage
- **Identity & Access**: Google Cloud IAM Service Accounts

## Architecture Diagram (Mermaid)
```mermaid
{mmd_doc.strip()}
```

## Infrastructure Blueprint (Terraform)
```hcl
{tf_doc.strip()}
```

## Validation results
{val_doc.strip()}

## Deployment & Operations Runbook
1. Initialize Terraform: `terraform init`
2. Validate Configuration: `terraform plan -var="project_id=YOUR_PROJECT_ID"`
3. Deploy Blueprint: `terraform apply`
