Nine models.
One consequential test.

Mission: “Design and build the strongest working digital learning experience you can create from the supplied HSE publication HSG253.”

The brief required a lifecycle view, energy and hazard reasoning, an isolation-method laboratory, a centrifugal gas-compressor scenario with at least eight consequential decisions, change and reinstatement challenges, an offline expert coach, competence assessment and report, accessible interaction, and a built-in design note, source map and test report.

Core learning loop: Observe → Interpret → Decide → Act → See consequence → Explain why → Apply again.
