Read-only by design
Define a telemetry connection that cannot issue equipment commands. Review that boundary for each proposed site before a pilot begins.

INTELLIGENCE BELONGS WHERE THE DATA LIVES.
01 / THE IDEA
Begin with what the system may do.
RAIN reads operational telemetry and produces advisories. Equipment control and safety systems remain separate. This boundary shapes the product: a model can suggest something to inspect, while the operator retains authority over any action.
Updates have to earn promotion
The simulator compares a candidate with the incumbent on held-out data. A rejected candidate does not replace the active model; its evaluation still belongs in the history.
Evidence travels with advice
Model versions and recorded events give operators context for an advisory. A history of model changes supports investigation without making the model a safety controller.
02 / IN PRACTICE
Put the thinking into practice.
Define the scope, preserve the boundary, and make the outcome something a person can inspect.
- 01
Set the permitted use
Name the operational question, the telemetry source and who reviews advisories. Keep equipment actuation outside the integration.
- 02
Challenge the assumptions
Include missing signals, stale readings and changing operating conditions in the proposed evaluation. Agree when an output should be withheld or reviewed.
- 03
Verify at the site
Test signal quality, alert usefulness and sustained operation on the target hardware. Simulation results alone cannot establish field readiness.
03 / A FEW DETAILS
Worth understanding.
Is RAIN a plant safety system?
No. It is an observe-only intelligence system under development. Existing control systems, safety procedures and operator responsibilities remain separate.
Does a signed history certify the system?
No. Recorded history is evidence to inspect. RAIN does not claim a safety certification, and hardware-backed signing remains unfinished product work.
BUILD WITH RAIN
One site. One question.
A useful next step.
RAIN is preparing for its first field pilot. Start by defining the environment, the data boundary, and what success should look like.
