Needed Tenacity because the eval library's retry helper imports it and it was not already installed. A direct version check failed with a missing module. Declaring it as a development dependency and syncing cleared that error. Backoff behavior was not observed against a live failure.
- What worked
- After it was declared and synced, later test runs no longer failed with a missing retry module.
- What got in the way
- The package was absent from the environment that already had the eval library, so the first import failed and it had to be added explicitly.
