+            ## Enroot Import Validation for Launch Scripts:
+            When reviewing changes to `runners/launch_*.sh` files, verify that the script properly transforms public Docker images to enroot local images for reproducibility.
+
+            **Expected pattern:**
+            The script should include an enroot import command like:
+            ```bash
+            srun --jobid=$JOB_ID bash -c "enroot import -o $SQUASH_FILE docker://$IMAGE"
+            ```
+            or similar variations such as:
+            ```bash
+            srun -N 1 -A $SLURM_ACCOUNT -p $SLURM_PARTITION bash -c "enroot import -o $SQUASH_FILE docker://$IMAGE"
+            ```
+
+            **Why this matters:**
+            - Ensures the exact same public NGC/Docker Hub image is used
+            - Makes benchmarks reproducible by anyone with access to the public image
+            - Prevents reliance on pre-existing local container images that others cannot access
+
+            **Validation Steps:**
+            1. Look for `enroot import` commands that convert `docker://` images to local `.sqsh` files
+            2. The image source should be a public registry (NGC, Docker Hub, etc.), not a local path
+            3. If the script uses containers but does NOT have an `enroot import docker://` pattern:
+               - This is a 🟡 **WARNING** issue
+               - Comment: "This launch script uses container images but does not appear to transform a public Docker image to an enroot local image using `enroot import -o $SQUASH_FILE docker://$IMAGE`. For reproducibility, please either:
+                 1. Add the enroot import pattern to pull from a public registry, OR
+                 2. Explain why this script has a different workflow (e.g., uses a different container runtime, pre-built images are acceptable for this use case, etc.)"
+               - Ask the developer to provide a reasonable explanation if the pattern is intentionally omitted
