cluster_stringer3_1432_excursion
Stringer 3 Tension Excursion · 14:32–15:08
Operator-1 raised Stringer 3 tension from 4.2 → 4.8 N at 14:32 to compensate for an alignment drift. CUSUM warning crossed at 14:35; recommendation declined; tension reverted only at 15:08 after action threshold. All 14 modules processed by Stringer 3 in the 36-minute window are members of this cluster.

Laminator 2 Membrane Fatigue · 08:00–12:00
Laminator 2 membrane health drifted from 0.94 (06:00) to 0.78 (action threshold) by 11:59. X-bar R warning crossed at 09:14; engineer accepted membrane swap recommendation but scheduled it for 12:00. 23 modules processed in the degraded-vacuum window; 17 developed bubble defects, 6 escaped.

cluster_stringer1_0835_excursion
Stringer 1 Tension Excursion · 08:35–09:18
Operator-3 raised Stringer 1 tension 4.2 → 4.7 N at 08:35, citing ribbon batch quality. Recommendation declined; tension reverted at 09:18 after CUSUM action threshold. 8 modules processed in the 43-minute window.
