Firstly, I love this project. Thank you to all the contributors.
I have been building a solution to the same problem and have found supporting architecture decision records has been very beneficial.
In my work, ADRs are key decisions about which software and infrastructure dependencies should be taken. They are suggested, reviewed and then approved.
In this project these details are added to the project file.
I would like to migrate to OpenSpec and was wondering how you felt about supporting ADRs in this way. I am happy to submit a PR but wanted to check in first.
