Interface MqlOneResult

Per-field model-side wrapper for a type: object resolution. The dispatcher lands this on model[fieldName] after running MQL, bundling everything a controller might need:

• stuff: the resolved Stuff, or null when MQL produced no match. (Inherited from MqlOne.) Distinguished from the field being absent on the model (player typed nothing) — controllers can tell the two apart.

• via: sub-feature attribution (exit for direction matches, detailPath for detail drills, etc.). (Inherited from MqlOne.)

• raw: the player-typed text post-desugar, before MQL replaced it with the resolved Stuff. Always present when this wrapper exists.

• prep: lowercased preposition the matcher consumed for this field per the YAML's prepositions: declaration. Absent when no preposition was declared or none typed.

Controllers destructure directly:

const { stuff, via, raw, prep } = model.target;
