Source facts with page provenance (motion, quarter-cycle start, stations,
Morison c_d/added-mass c_i definition, Table 1 as computed reference, no
recovered uncertainty); lab-frame kinematics with base at the right turning
point, interval-average wall velocity and force attribution, explicit cycle
indexing; T multiple of 360 steps; native-channel domain sensitivity order;
fluid-only interpolation; periodic gate with fixed-scale waveform/profile
settling, N=3, cap 30, common window; engineering criteria labelled as such.
