I recently read some interesting research on GitHub's Verified commit workflow. The issue isn't a break in Git, GPG, or commit signing itself, but rather how the Verified badge can be interpreted in certain edge cases. It's a good reminder that a cryptographically valid signature doesn't automatically establish the provenance or intent of a commit.

Here's a technical breakdown covering how the trust model works, the affected scenarios, GitHub's response, and what maintainers can do to avoid relying solely on the Verified badge during code review.
