Prompt

Write the MATLAB enforcement gate statement that verifies whether 'destFile' resides within the RoadRunner project directory before calling importScene.

What was checked, without and with the skill
Checked	Without skill	With skill
The statement retrieves projectFolder from status(rrApp)	Missed	Passed
The assertion uses startsWith to verify destFile is inside projectFolder	Missed	Passed

RoadRunner Scene Import

Import map files into a RoadRunner scene for visualization, verification, and building.

When to Use

Importing a .rrhd file into RoadRunner for visual verification
Importing an OpenDRIVE .xodr file into RoadRunner
Verifying converted maps after Lanelet2-to-RRHD or other conversions
Configuring build options (asphalt surfaces, bridge detection, junction preservation)

When NOT to Use

Launching RoadRunner or managing projects — use roadrunner-core
Building RRHD map content — use roadrunner-rrhd-authoring
Converting Lanelet2 to RRHD — use roadrunner-convert-lanelet2-to-rrhd
Looking up asset paths — 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.
Requires rrApp from roadrunner-core. Do not launch or connect to RoadRunner in this skill. If rrApp does not exist, invoke roadrunner-core first.
Always copy file to project folder. Use status(rrApp).Project.Filename and copyfile() explicitly in every import workflow — never omit or hide behind a variable.
Always set bridgeOpts.IsEnabled = true explicitly. Never rely on constructor defaults for bridge auto-detection.
Run enforcement gates before importScene. File location, extension, and build-option checks are mandatory.
Load before Build by default. Use ImportStep="Load" unless user explicitly requests a full build.
NEVER hardcode DetectAsphaltSurfaces = true for converted maps. Always inspect the RRHD for closed-loop topology first. Closed-loop networks (most Lanelet2 conversions) MUST use DetectAsphaltSurfaces = false — asphalt detection fills the interior of loops.
ALWAYS preserve junctions when they exist. If tempMap.Junctions is non-empty, you MUST set overlapOpts.IsEnabled = true, overlapOpts.PreserveJunctionLanes = true, and overlapOpts.PreserveJunctionShape = true. Never rely on RoadRunner's auto-detection to re-infer junctions — it discards authored geometry.

Prerequisites

A valid rrApp handle must exist (produced by roadrunner-core skill)
A RoadRunner project must be open
If rrApp does not exist, invoke roadrunner-core first to launch and connect

Connection, launching, and project lifecycle are owned by roadrunner-core. This skill assumes rrApp is already available.
