ContextKeys

Standard keys for FlippingExecutionContext parameters.

These constants provide consistent, type-safe key names for commonly used context parameters. Using these keys instead of raw strings helps prevent typos and enables IDE auto-completion.

Example usage:

val context = FlippingExecutionContext(
    ContextKeys.USER_ID to "user-123",
    ContextKeys.REGION to "EU"
)

val userId = context.get<String>(ContextKeys.USER_ID)
