+ - `A3-1-5` - `NonTrivialNonTemplateFunctionDefinedInsideClassDefinition.ql`:
+   - Mark this as an `audit` query. As a consequence, it will no longer be run as part of the default query suite for AUTOSAR. It can still be run as part of the `autosar-audit.qls` query suite. The query has been downgraded because the rule allows for functions to be declared in the class body if they were "intended" to be inlined, and that developer intention cannot be determined automatically from the code.
