This guide covers the hldmsserver module in AlphaGSM.

hldmsserver is currently PASSED on the documented Ubuntu 24.04 Linux baseline. The current GitHub integration lane still exercises both process and Docker runtime selection, and the validated Linux lifecycle stays aligned across both backends while local runs remain process-backed by default unless you opt into the Docker backend.
