Backend

The scaffolded backend is an opinionated Actix-web starter. It is structured around a small set of focused modules:

• configuration.rs — YAML-based configuration loading. Walks up the directory tree to find configuration/base.yaml. Respects the DRYDOCK_BACKEND_PORT environment variable set by the dev server.
• startup.rs — Wires up the Actix-web server, routes, and middleware.
• error.rs — ApiError enum implementing ResponseError, mapping variants to HTTP status codes.
• response.rs — Re-exports ApiResponse<T> from the shared crate for use in handlers.
• telemetry.rs — Tracing subscriber setup with Bunyan-formatted JSON output.
• static_assets.rs — Serves embedded frontend assets in release builds. Compiled out in development.
• api/mod.rs — Route configuration with starter endpoints: /api/health_check, /api/hello, /api/status.

Integration tests

Integration test scaffolding lives in backend/tests/api/ with a TestApp helper that spawns the server on a random port, plus a sample health check test to build on.
