Rate Limits

BatteryBee does not currently implement application-level quotas, rate-limit headers, or tenant-aware throttling in the FastAPI backend.

Actual limits today

Browser and service-wrapper request timeouts bound long-running planner and export calls.
Backend workers are limited by the process and host resources running uvicorn or the deployment runtime.
Heavy STL, STEP, DXF, archive, and busbar split exports can consume more CPU and memory than planning calls.
Firebase limits and security rules apply to project metadata and imported file storage.

Before public exposure

Add authentication, owner checks, body-size limits, quotas, timeout policy, and observability before exposing the backend as a public multi-user API.
