Why did CMake link the wrong Core?

Exo 1.0.0 package metadata pairs with Core 1.4.0. Clear the old build tree and ensure CMAKE_PREFIX_PATH contains no earlier version.

Why must automatic discovery find one device?

A configuration without a port must resolve one physical device. For multiple devices, discover first and give every ExoConfig an explicit port and logical name.

Why is an IMU std::nullopt?

The hardware may not expose it. Inspect capabilities.imus and components.imus first.

Why did subscription callbacks stop?

Keep the Subscription value alive and ensure the Exo domain is started and a runtime driver is advancing.

Are assistance or calibration APIs available?

Version 1.0.0 does not expose raw QnTP, DFU, encoder-zero calibration, wireless provisioning, active assistance, algorithm targets, retargeting, or skeleton APIs.
