Summary

You can now explain what Cogitave Diyar is, why it is built edge-autonomous, and where the platform stops and a solution begins.

In this module, you:

• Explained why Diyar is edge-autonomous: the device is the sole authority over safety and evidence, and a run completes the whole loop - start, sweep, evaluate, journal, drain, reconcile - with the network, the cloud, and the operator's phone all absent.
• Separated the platform (enrollment, tenancy, the evidence lifecycle, signed updates, an audited console, a fail-safe actuation model - the same for every industry) from a solution (a certified verdict engine plus a signed device profile), and placed ISPM-15 correctly as the first solution, not the product.
• Read the diyar:<layer>:<name>;<major> id grammar used across every solution, engine, profile, and app in the platform.
• Walked the three architectural zones - the edge (sole actuation and evidence authority), the cloud/on-prem control plane (requests and mirrors, never actuates), and the client surfaces - and can state precisely which one can ever energize hardware.
• Learned, honestly, which parts are still early: the kiosk and web portal ship as minimal stubs today, and DIYAR_HAL=real refuses to start pending hardware-in-the-loop validation.

Next steps

• Safety and evidence in Diyar - the next module in Introduction to Cogitave Diyar, on the layered safety design behind de-energize-to-trip and how a single reading becomes tamper-evident evidence.
• Keep the platform/solution split and the diyar:<layer>:<name>;<major> id grammar in mind - they carry through everything the rest of this path covers.
