OpenXRSpatialComponentPlaneSemanticLabelList

Native component-data container for QuerySnapshot, not a tracker, game Entity or ready geometry. OpenXRSpatialQueryResultData must be first in a query array; other components use the same row indices. Validate component support, successful query and row state before reading.

SetCapacity allocates memory rather than device data. Query-result GetCapacity reports allocated array length and can be nonzero without any query. Never consume stale storage after a failed/incomplete query. Final output counts are not separately public between the two passes; changing runtime result counts was not tested.

Buffer getters need the same live snapshot. Copy needed arrays/strings before FreeSpatialSnapshot or the end of a borrowed capability callback. Never double-free that snapshot; keep owned containers alive through use. Raw poses are not ready GlobalTransform values and do not automatically apply WorldOrigin/reference frame/WorldScale.

Semantic enum for a filled row, such as Floor/Wall/Ceiling/Table or Uncategorized. Not an arbitrary PlaneLabel string or surface material. Do not interpret Uncategorized/unknown as Floor; invalid indexing returns MAX_ENUM sentinel.

Integration guide. Eleven Windows XR-off checks covered metadata/capacity/virtual dispatch without reading unfilled memory. Real snapshots, buffer values, pose/UUID/marker decoding, headsets and export remain untested. Engine unchanged.
