# Python Backend Boundaries
- Keep `backend/src/main.py` thin. Add request/response wiring there, but keep orchestration in `backend/src/manager.py`.
- Keep live ESI calls, token refresh, waypoint updates, and market-window side effects inside `backend/src/esi/`. Do not introduce direct ESI `requests` calls in `graph.py`, `market.py`, `arbitrage.py`, `pathfinder.py`, or `route.py`.
- Treat `Manager` as the mutable state boundary. If you add background work, keep thread and polling ownership explicit instead of spreading shared state across modules.
- Preserve the current data-oriented style in the route-planning pipeline: dataclasses, module-level constants, and functions that transform orders, trades, and graph data.
- The active frontend depends on `/route`, `/route_info`, `/create_route`, `/data_stream`, and `/open_market_window/{type_id}` on `http://localhost:8000`. Keep those contracts stable unless the task includes coordinated frontend changes.
- ESI-backed code needs local auth and data files that are not checked in. Avoid assuming clean-room execution unless the task is specifically about environment setup.
