SHA hashes in 'main' branch are different from those in the 'origin/main'

Hello,
i am experimenting with Espresso, trying the switchboard recipe on air-traffic-control data.
I noticed my local SHA hashes in 'main' branch are different from those in the 'origin/main'.
I tried to 'pull' from the 'origin', but i am getting conflicts due to that.

- Can it be caused by the local installation via `pip install --editable .` ?
- Have you seen this issue before ? Is it normal, or did I do something wrong ?
- How do you edit code, contribute and test locally normally ?

Best regards,
Karel

The issue names no file, test, or entry point. Start by checking the repository's existing guidance for editable installs, branch synchronization, and local testing, then verify the reported main/origin-main situation. Done means documenting the cause of differing hashes and the normal edit, contribution, and test workflow.
