Enum StationKind 

pub enum StationKind {
    Point,
    Gate,
}

What shape a station is (spec-0052 §3) — a cell to stand a body at, or a volume with a block that seals and clears.

The kind is the station’s shape, never its purpose: there is no enum of bonfire / camera / shop, for the same reason Node::intent is free-form — a purpose vocabulary would be this month’s genre wearing a schema’s clothes. A bonfire, a camera subject and a shop counter are the same Self::Point to every check in this engine.

Why two shapes and not three

spec-0052 §3 describes three, “mirroring the three shapes a piece anchor can take (a cell to stand a body at; a volume; a volume with a block that seals and clears)”. Those are the three shapes a piece anchor may be declared in; they are not three shapes anything consumes. This engine resolves an anchor to ResolvedAnchor::Point or ResolvedAnchor::Gate and to nothing else, and a piece anchor declaring a bare region with no block is read as a gate whose fill block is minecraft:air.

Every volume-shaped consumer — a lethal_volumes[] region, damage-players’s in, a volley kill zone, collapse’s ceiling, begin-stealth, fill-region, clear-region — is a crate::StealthZone, an anchor-centred box resolved from a point plus an extent. The engine states the reason in its own words at Verb::FillRegion::region: an anchor-centred box rather than a prefab region anchor, “because the assembled model deletes every gate-region anchor’s cells, so a slab declared that way would already be gone”.

So a third region variant would be a name a campaign could declare and bind and no reference site could consume — an inert surface whose stand-in would have to be a gate region the assembled world then deletes. It is left out deliberately, and spec-0052 §11’s falsifier is what decides it: the first campaign brief that cannot state its place without one is the evidence, and the answer is a first-class surface with a consumer, or a refused feature.

Variants

Point

A cell to stand a body at — where a quest step, an NPC, a wave seat, a cutscene subject, an affordance or a volume’s centre lands.

Gate

A volume with a block that seals and clears — what open-gate, close-gate, a shortcut and a timed-gate address.
