Struct Question 

pub struct Question {
    pub root: PathBuf,
    pub room: Result<Headroom, String>,
    pub floor_spec: String,
    pub requested_bytes: u64,
    pub held_bytes: u64,
    pub namespace: String,
    pub growth: GrowthFacts,
    pub machine: MachineFacts,
}

Everything answer decides from. Built by crate::control_plane::CoreControlPlane out of the disk gate and the namespace’s meter; built by hand in the tests, which is the point.

Fields

root: PathBuf

The store root the numbers are of.

room: Result<Headroom, String>

The one statvfs, or the OS’s reason it failed. Err is CapacityVerdict::CapacityUnmeasured — never a yes.

floor_spec: String

--disk-floor as configured, for the reason line.

requested_bytes: u64

The cap being contemplated.

held_bytes: u64

What the namespace already holds (Usage.Read’s pack_bytes).

namespace: String

Whose cap is rising; empty asks about bytes that are not here yet.

growth: GrowthFacts

machine: MachineFacts

The box, for the product-scope fields. Independent of the question: the same cores and RAM are reported whatever cap was asked about.
