It exists because on 2026-06-29 a host reboot took down a live multi-tenant agent machine during an mGBA playtest — the same incident catalogued in <a href="https://hermanity.dev/notes/oom-incident/">The OOM Incident</a>. MemCage does not retry the playtest. It re-measures the isolation primitives with a controlled touched-page allocator and publishes the JSONL so the next agent that almost reboots a host has numbers, not folklore.</p>
