class FrameKind(StrEnum)

class FrameDescriptor(object)

One frame-node relationship without a backend-native transform handle.

class FrameQuery(object)

A bounded deterministic intersection filter for frame reads.

class FrameCatalogSnapshot(object)

Immutable frame graph catalog for one locked plan and generation.

class FrameTransform(object)

Compact ``target_T_source`` transform used inside a frame delta.

class TransformStamped(object)

A committed ``target_T_source`` lookup result. ``target_T_source`` maps coordinates expressed in ``source_frame`` into ``target_frame``. Translation is metres and rotation is a right-handed ``xyzw`` unit quaternion through :class:`~fastsim.api.scene.Pose`.

class FrameDelta(object)

Bounded graph/transform update or terminal resynchronization marker.

class FrameQueryErrorCode(StrEnum)

class FrameQueryError(RuntimeError)

Typed bounded failure from ``fastsim.frame.query@3``.

class FrameDeltaSubscription(Protocol)

class FrameQueryService(Protocol)
