## Design Questions

### Billing without double charging?
Every usage log entry has a unique request_id. A billing job only
processes entries with status "pending", marks them "billed" after
charging, and never processes the same request_id twice.

### Scaling to 100K agents?
Move agents to PostgreSQL with a full-text search index. Store usage
logs in an append-only table. Use Redis counters for usage totals
instead of scanning all rows every time.
