Struct PlacementControl 

pub struct PlacementControl {
    pub canonical_env: &'static str,
    pub aliases: &'static [&'static str],
    pub flag: Option<&'static str>,
    pub kind: ControlKind,
    pub value_form: &'static str,
    pub description: &'static str,
}

A single canonical control: its primary env var, accepted aliases, the equivalent CLI flag (if any), and human/agent-facing value semantics. This is the registry rch capabilities renders so agents stop discovering knobs by folklore.

Fields

canonical_env: &'static str

Canonical environment variable name.

aliases: &'static [&'static str]

Accepted aliases (documented, mapped to the canonical control).

flag: Option<&'static str>

Equivalent CLI flag, when one exists.

kind: ControlKind

Which family the control belongs to.

value_form: &'static str

Accepted value form (e.g. worker id, 0|1, secs).

description: &'static str

One-line description of the effect.
