**As** a developer
**I want to** know where Begin of the insertionthereEnd of the insertion Begin of the deletion foreign keysEnd of the deletion may Begin of the insertionbeEnd of the insertion Begin of the deletion have been missed forEnd of the deletion a Begin of the insertionmismatch between foreign keys and modelEnd of the insertion Begin of the deletion given ModelEnd of the deletion association Begin of the insertiondependent optionEnd of the insertion
**so that** we avoid potential bugs (e.g. emoji reactions <mention class="mention" data-id="61708" data-type="work_package" data-text="#61708">#61708</mention> )

**Acceptance criteria**

* Add Begin of the insertion `active_record_doctor`End of the insertion Begin of the deletion &nbsp;`active_record_doctor`End of the deletion dependency to OpenProject core and configure important details.


**Technical notes**

* `bundle exec rake active_record_doctor:missing_foreign_keys` should work Begin of the insertion

* `bundle exec rake active_record_doctor:incorrect_dependent_option`End of the insertion


**Out of scope**

* Integrating with our CI - creating a GitHub workflow. This can come later if the tool provides useful information
