System-interaction: information about mode of operation

**SC profile shall define means through which the API user can obtain information about the current mode of operation.**

Rationale: SC profile may define different functionality for different modes of operation. If the API user is not able to determine which mode is current, it may invoke or rely on incorrect API functionality.

Example: SC profile can define function `Mode getMode()` which obtains the current mode, where `Mode` can be defined as `enum class Mode { non_safe, safe }`.

No file, test, or entry point is named. Start by reviewing the SC profile requirement and the proposed getMode example; done means the profile defines an unambiguous way for an API user to identify the current mode of operation.
