Vacuum Hold Pressure · Laminator 2
X-bar R chart
warn 8 · action 12 mbar
Vacuum hold pressure drifted from nominal 4 mbar to 6.1 mbar by 09:14, crossing the 8 mbar warning during the showcase module's cycle (peak 7.8 mbar). After membrane replacement at 12:00, returned to 3.8 mbar.· Green dashed: If predictive maintenance triggered at 06:00.
Membrane Health · Laminator 2
I-MR chart
warn 0.85 · action 0.78 index
Membrane health degraded steadily from 0.94 toward action threshold 0.78. Crossed warning 0.85 at ~08:00 — six hours before scheduled replacement.
Lamination Bubble Rate · Laminator 2
p-chart
warn 0.02 · action 0.04 proportion
Per-lot bubble defect proportion crossed action threshold 4% during the affected 4-hour window, returning to nominal after the 12:00 membrane swap.

This page demonstrates full provenance for three showcase modules AND their full cluster genealogies — 53 additional cluster modules whose journeys share the same upstream causal events as the showcases. In production deployment, every module's complete genealogy and every cluster's full membership is tracked automatically. This demonstration shows what that looks like at the cluster scale.
