Execution Core

Core () on a connected repository card picks the Signaloid C0 core the Compute Engine runs the repository on. It opens the Select Active Core dialog, the same one the Code Playground toolbar opens, listing every Signaloid C0 core available to your account. These are the default Signaloid Cores and any custom cores you have created. You can preview the specification of any core in the dialog before you select it.

Figure 1. Opening Core on a connected repository card and picking a different core in the Select Active Core dialog.

Core highlights while a core is set on the repository. It switches to a warning style in two cases:

The repository carries a signaloid.yaml declaring a minimum core configuration, and the active core does not meet it.
The class of the active core is not one the repository lists under Compatibility. A repository without a Compatibility key counts as cloud only, so a C0-SD, C0-microSD, or C0-microSD-plus core also triggers this warning.

When you open the dialog from a connected repository card, it marks each core that fails either check, and shows a warning when you select one. The warnings do not block the build. See How to Create a Custom Core for the default cores and how to design your own, and The "signaloid.yaml" File for repository-side core requirements.
