warn 8 · action 12 mbar
Single-cycle excursion to 7.2 mbar at 09:34 (just at warning threshold). Insufficient for sustained alert but enough to lock a gas pocket into this module.
Membrane Health · Laminator 1
I-MR chart
warn 0.85 · action 0.78 index
Laminator 1 membrane has been below warning threshold (0.85) for 24+ hours, last replaced 2,650 cycles ago. Slow degradation enabled the single-cycle excursion.

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.
