bee-raph/pear-airtchang — reverse-engineered prompt

Build me a local demo called Pear Airtchang, basically a cheap Apple AirTag style fleet tracker for interviews. I want to run it with Docker Compose and open a web map where different demo companies can log in, then only see their own moving devices in real time. Use .NET 10 for the backend and Angular with Leaflet for the map. The browser should get live updates, show simulated global Pear devices, Israel Strawberry trucks, France Banana sales vehicles with some stored history, and Planes from OpenSky when available.

Please include simple demo accounts like pear, strawberry, banana, and planes, with company scoped access using tokens so one company cannot subscribe to another company’s devices. Keep the hot latest positions fast, stream updates through the backend, and include basic logging dashboards so I can demo errors, plane rate limits, and generator throughput. Add a few unit and integration tests, and make the whole thing start with one Docker Compose command. Look up current docs online if you need to.
