Issues

• KCL: union() rejects an extrude + sweep operand pair - a helical thread cannot be unioned into its own fastener

• Angle violates the PartialEq/PartialOrd contract across units; rtc_frames_per_second is u8 but the stat is a double

• Documented import/export defaults are required on the wire (OBJ/PLY/STL/glTF lack #[serde(default)])

• modeling-session response timeout never fires on a silent engine; a new ErrorCode makes the whole failure response undecodable

• Opposite<T> JSON Schema declares a string, but the serde wire format for Other(t) is an object

• Fillet radius past the feasible limit silently builds wrong geometry; the loud error only fires in a ~0.01-wide pocket

• bounding_box and center_of_mass use different coordinate frames in the same analyze response

• Boolean subtract fails ('cannot handle this 3D subtraction yet') when tools cross prior-cut edges — with absolute-scale sensitivity

• Engine cannot re-import its own exports: STEP fails, glTF fails until Zoo's own KITTYCAD_boundary_representation extension is stripped

• Text-to-CAD: deduplicated prompt submissions return completed jobs whose outputs are unreachable (no /async/operations record)

• Text-to-CAD: internal transport failures surface raw cluster DNS in the error and burn ~8 min before failing

• Allow Face API edge specifiers to preserve grouped face references (multiple faces from region->extrude)
