## Automation and API

- The running desktop application serves a local REST API with an OpenAPI
  description at http://localhost:<port>/api-docs (the port is assigned at
  startup). Swagger UI is served by the same instance.
- Endpoints cover projects, observation registers, video data, import, export,
  file streaming and observer agreement (Cohen kappa, Krippendorff alpha,
  percentage agreement).
- Jupyter notebooks run inside the application with the observation data
  preloaded as a pandas DataFrame; numpy, matplotlib and scipy are available.
