• replays stage 1's two-zero tracker over all 521 stage 3 sweeps in time order, float beside the integer port
• feed rule: 30 % duty gate, settled coast in the crest column, torque off; no current gate
• start rule: seed the awake zero from the asleep zero plus the step line at the rail, at boot and past a 0.32 V rail move
• one constant, the drive feed's offset (0.67 counts), held out by day and measurable by the servo itself
• whole design 0.41 counts rms over 975 runs against 0.88 for stage 1's tracker; alpha 2^-13 stays
• no capture of its own; result file, step table and alpha scan under results/
