The deploy page read /proc's host-wide figures (system.GetMemoryMB) while the install check reads the guest cap and the installed apps' committed requests; on 9202 the page said 12,637 MB needed where the check counted 2,648. Both now read stacks.InstallMemory. TestR1125_InstallMemoryIsTheChecksReading, red-proved. Claude-Session: https://claude.ai/code/session_0159rPz1ZhFKsS53msqPYxtS
