Kind	Name	Description
`struct`	`Vec2f`	Two-component float vector used for planar rates, flow, and image motion.
`struct`	`Vec3f`	Three-component float vector used for ENU world vectors and FLU body vectors.
`struct`	`Quaternionf`	Unit quaternion in Hamilton convention, component order w, x, y, z. It rotates body-frame FLU vectors into the world ENU frame: v_enu = q * v_flu * conjugate(q). Identity rotation is 1, 0, 0, 0.
`struct`	`RateTriplet`	Roll, pitch, and yaw rates or rate setpoints about the FLU body axes.
`struct`	`CovarianceUpperTriangle21f`	Upper-triangular 6x6 covariance matrix stored row-major as 21 float values. State order is x, y, z translation followed by rotation about x, y, z.
`enum`	`Severity`	Text and diagnostic severity levels following RFC 5424 syslog numbering.
`enum`	`CommandResultCode`	Result of command or transfer request execution.
`enum`	`GnssFixType`	GNSS receiver fix quality.
`enum`	`BatteryChargeState`	Battery or power-source charging state.
`enum`	`BatteryFunction`	Role a battery or power source plays on the vehicle.
`enum`	`BatteryType`	Battery chemistry or power-source type.
`enum`	`MissionState`	Mission execution state.
`enum`	`GeoAltitudeFrame`	Altitude reference frame for geographic commands and mission items.
`enum`	`LocalFrame`	Local coordinate frame selector for local-frame commands.
`enum`	`ReferenceFrame`	Reference frame identifiers for odometry and pose products.
`enum`	`TopicId`	Stable numeric identifiers for well-known Synapse topics. Values are contiguous and mirror the SynapseMessage union order in transport.fbs.
