▸case-01 I need to modify `services/media_store.py` to support cloud blob storage alongside local file saving. Right now, every function hardcodes local filesystem paths.

▸case-02 We have an active critical vulnerability (CVE-2024-9999) in our payment processing module `payments/checkout.py` where unescaped input leads to SQL injection.

▸case-05 We need to add support for multiple currencies (USD, EUR, JPY) to `billing/calculator.py`. Currently, all methods assume amounts are floating-point numbers in USD.

▸case-06 Our REST API router in `api/router.go` currently handles requests without checking permissions. We need to add RBAC (Role-Based Access Control).
