The login request's memoryStats is a run of short parts with no separators (process working set and private bytes, memory load, physical memory, commit limit, the 32-bit client's own address space, peaks). ParseMemoryStats splits it into numbers; a text cut short keeps the parts before the cut. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
