<Badge color="blue">AI Agent</Badge>

Protocol for reading the memory budget and pressure of a gateway host.

Pure contract the gateway implements over its own process: report the
container's memory limit (from the cgroup v1/v2 memory limit) and the
current anonymous (non-reclaimable) RSS, so the eviction budget tracks the
*real* container ceiling rather than a hard-coded number. Both return
`None`/`0` gracefully when the platform can't report them, so the
planner degrades to a no-op instead of crashing the gateway it protects.
