Enum IoMaxStatus 

pub enum IoMaxStatus {
    Enforced,
    Unavailable,
    NotRequired,
    NotProbed,
}

Whether the declared capabilities.resources.cgroup_io_bytes_per_sec ceiling is actually on this session’s cgroup scope.

Four states rather than a bool because “the write failed” and “there was never a scope to write to” are different findings with different remediations, and neither is the same as “this value was never established”. Self::NotProbed is the Default so a report nobody filled in claims nothing.

Variants

Enforced

The io.max write succeeded against the device backing the workdir. The ceiling is on the scope.

Unavailable

A scope exists and the io.max write did not succeed. memory.max, pids.max and cpu.max are still enforced on it; I/O bandwidth is not bounded. What W-SEC-021 reports.

NotRequired

No scope was asked for: either this capsule declares no way to reach a native subprocess, or this is not Linux, where cgroups cannot exist. Not a shortfall — there is no process tree for a ceiling to apply to.

NotProbed

Nobody asked. The Default, so a IoMaxReport that was constructed rather than measured asserts nothing about the host.
