Your Git Log Is a Database. You’re Just Writing Diary Entries.
Most developers treat Git trailers as a niche feature for co-authors and sign-offs. They’re wrong. Trailers are a hidden contracting mechanism that turns every commit into a mini-API call — encoding ticket IDs, review status, and deployment flags directly into your history. If you use Magit, you can configure custom trailers without leaving Emacs, making your git log a structured database instead of a diary nobody reads.
