E_NO_HISTORY
No code changes to sync against
helpbase sync asked git for a diff, and git returned nothing.
Common causes
- The `--since` rev is identical to HEAD (no commits in between).
- You just cloned the repo and haven't made changes yet.
- The branch you're on hasn't diverged from the base branch.
How to fix
- Make some code changes, commit them, and re-run.
- Pass a deeper rev:
helpbase sync --since HEAD~20. - Pass an explicit base:
helpbase sync --since origin/main.
