MemoryPressureProtocol
Defined in the protocols module.AI Agent 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.
Methods
cgroup_limit_mb()
Return the container memory limit in MiB, or
None if unknown.anon_rss_mb()
Return current anonymous (non-reclaimable) RSS in MiB.
