Realism Features

Jinja2 macros eliminate boilerplate across 22 templates
4 identity types — AssumedRole (65%), IAMUser (20%), AWSService (12%), Root (0.5%)
Shared state correlations — AssumeRole generates temp credentials reused by subsequent API calls
Error injection (~4%) — 20 realistic error scenarios mapped to specific API operations

Multi-account environment — 3 AWS accounts (production, staging, development)
10 IAM users across 7 departments, 12 IAM roles with distinct trust services
