Newest valid reading of every mapped signal, exactly as collected from the plant (OPC UA subscription or historian export on the collector box). Each value carries its own timestamp - the page never invents liveness the data does not have.

Two independent advisory sources, each shown as reported; nothing is merged or re-scaled.

A withheld advisory is the product working: the reason names exactly what the data could not support.

Physics mode: the membrane transport model is calibrated on each train's own record; every settable value is predicted, contract-gated and priced, and every refusal is named. Read-only: every step is taken by a person.

Where several identical units run in parallel, one of them going wrong can be invisible in its own reading — if the measurement shares a term across units, a fault in one moves all of them together and reads as a shared upstream cause. What shows it is each unit's distance from its siblings, measured against what that unit itself normally does.

The sheet the plant fills in by hand every morning, built from the record instead. Every figure states the basis it was computed on, because a compliance number that cannot say which samples it used is not one anybody can defend.

Chemical dosing monitor: tank levels, dosing-pump status and product-water pH, straight from the mapped instruments. Values carry their own timestamp; a low tank or an out-of-band pH is flagged, nothing is smoothed.

Every number on this dashboard has a stated method behind it. This page is the audit trail for a technical reviewer: what each index is, where its formula comes from, and what the product refuses to compute.
