  We present a scalable scheme for executing the error-correction cycle of a
monolithic surface-code fabric composed of fast-flux-tuneable transmon qubits
with nearest-neighbor coupling. An eight-qubit unit cell forms the basis for
repeating both the quantum hardware and coherent control, enabling spatial
multiplexing. This control uses three fixed frequencies for all single-qubit
gates and a unique frequency detuning pattern for each qubit in the cell. By
pipelining the interaction and readout steps of ancilla-based $X$- and $Z$-type
stabilizer measurements, we can engineer detuning patterns that avoid all
second-order transmon-transmon interactions except those exploited in
controlled-phase gates, regardless of fabric size. Our scheme is applicable to
defect-based and planar logical qubits, including lattice surgery.
