Greptile Summary

This PR fixes a typo in docker/.env.base where the environment variable was misspelled as ISAACSSIM_VERISON instead of ISAACSIM_VERSION, which was causing Docker workflow and build failures. The contributor's name is also added to CONTRIBUTORS.md, though it is inserted slightly out of alphabetical order.

Confidence Score: 5/5

Safe to merge — the fix is correct and the only remaining finding is a minor alphabetical ordering issue in CONTRIBUTORS.md.

The core change (typo fix in .env.base) is straightforward and correct. The single P2 finding (out-of-order contributor name) is a trivial style issue that does not block merge per the confidence guidelines.

CONTRIBUTORS.md — entry for Dhyan Thakkar needs to swap with Dhananjay Shendre to restore alphabetical order.

Vulnerabilities

No security concerns identified.

Important Files Changed

Filename	Overview
docker/.env.base	Corrects the misspelled variable name from ISAACSSIM_VERISON to ISAACSIM_VERSION, which was causing Docker build failures.

LGTM ✅ Good catch — ISAACSSIM_VERSION → ISAACSIM_VERSION fixes the env var name to match what the rest of the Docker/build tooling expects (docker-compose.yaml, Dockerfile.base, isaaclab.sh, CI workflows, etc.). Without this fix the version variable would silently resolve to empty in Docker builds.

Contributors list addition looks correct (alphabetical order maintained).
