Issue dossier

The listing frames SAOv3 as Rare Circuit's proposal over I2C, says the device does not support ARP or hot plugging, and describes general host control capabilities. It does not publish an authoritative final standard, electrical I2C details, command schema, host test matrix, version negotiation, port-detection result, hot-plug safety evidence, ARP alternative, backwards-compatibility policy, or proof that a particular badge implements the interface.

A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
