## Description

Convert Lanelet2 maps (.osm) to RoadRunner HD Map (.rrhd) format using MATLAB. Use when converting Lanelet2 maps into RoadRunner Scene Builder, building driving scenes from open-source map data, or transforming road network definitions for simulation.

# Lanelet2 to RRHD Converter

Converts Lanelet2 `.osm` files to RoadRunner HD Map `.rrhd` format.

## When to Use

- Converting a Lanelet2 `.osm` file to RoadRunner HD Map `.rrhd` format
- Importing Lanelet2 maps into RoadRunner via MATLAB
- Building RRHD from `.osm` sources that contain `type=lanelet` relations
- Need full pipeline: parse, geometry, topology, semantics, junctions, barriers, signs, markings

## When NOT to Use

- Input is a standard OpenStreetMap file (highway=* ways without `type=lanelet` relations)
- Input is OpenDRIVE `.xodr`, import directly via `roadrunner-import-scene`
- Building RRHD from scratch without a source file, use `roadrunner-rrhd-authoring`
- Only need asset path lookups, use `roadrunner-asset-mapping`

## Key Rules

- **Always write to .m files** when executing code. Never put multi-line MATLAB code directly in `evaluate_matlab_code`. Write to a `.m` file, run with `run_matlab_file`, edit on error. Exception: if the user asks to "show the pattern" or says "do not execute", show code inline without writing files.
- **ALL pipeline steps are mandatory.** Do NOT stop after writing lanes/boundaries, junctions, curve markings, barriers, signs, and speed limits must all be built.
- **Boundary geometry is IMMUTABLE.** Never flip, resample, project, or modify boundary points.
- **One boundary object per way.** Deduplicate via `wayToBndID` map.
- **Detect alignment for EVERY lane.** Never hardcode `"Forward"` for all boundaries.
- **Center line density: 1 point per meter minimum.** Use `max(10, round(avgLen), nLeft, nRight)`.
- **Run enforcement gate before `write()`.** Alignment, spatial, extension, and completeness checks are mandatory.
- **No nested function definitions.** Code runs in script context, all logic inline or anonymous functions.
