Shizen Connect and ERAB
Shizen Connect is referenced as a Japanese VPP platform. The talk avoids programme MW, device-count, and asset-role claims unless a primary programme source states them.

Technical appendix
The live talk keeps architecture, choreography, frequency response, and aggregation focused. The interactive deck retains the technical demonstrations for follow-up discussion.
