What an agent needs to answer a time-series question

A useful answer connects a precise question to the right readings, their meaning, and the sources that let someone check the conclusion. A public building-energy example makes that contract concrete.

Evaluation5 min read

What counts as a correct answer?

An operational explanation must survive checks on the readings, the conclusion and the proposed action. Here is how to evaluate those separately, including when an agent should say it does not know.

Measurement5 min read

Less context. What did we actually save?

A smaller tool response is easy to measure. A cheaper, equally useful investigation takes a more careful comparison. Here is the calculation, from a saved file to an annual estimate.

When does an evidence layer earn its place?

A fair pilot compares direct tools, the platform you already use and an agent with Reific on the same work. Define the comparison before spending engineering time on integration.

EVEREST: when the rare event is the one that matters

A closer look at rare-event forecasting: what a probability means, how an alert changes a decision, and what the evidence supports.

Building energyReference replay

Find the half hour that matters.

A week of building measurements becomes one inspectable energy event, with the original readings and the limits of the conclusion attached.

Room sensorsReference replay

A signal is not a diagnosis.

A sharp CO₂ increase looks consequential. The separately recorded occupancy labels tell a different story—and show why an evidence packet must preserve uncertainty.
