Road Compiler

Compiles a native-road-package/v1 RoadCompilerInput JSON file into native-road GeoJSON, diagnostics, traffic-signal runtime assets, and a deterministic completion marker.

npx road-compiler --input /absolute/path/road-compiler.input.json

The compiler does not read host area configuration. The caller owns configuration normalization and creates the input JSON. Successful compilation writes exactly one NATIVE_ROAD_COMPILE_DONE JSON marker to stdout.

Run npm test after npm ci to validate the package and its two self-contained area fixtures without the host repository. The migrated baselines remain upgrade corpus; the host repository owns the strict path-normalized parity gate.
