{"agent":"claude","input":"Upgrade Wagtail and Django to the latest versions compatible with this site's current requirements and Python runtime. Trace requirements.txt and its includes, read the relevant Wagtail upgrade notes and establish the existing test baseline. Use pip in an isolated environment and the repository's test settings. Run python manage.py check, python manage.py makemigrations --check --noinput and python manage.py test. Include only upgrades that pass these checks; leave out incompatible candidates and explain the exact failure. Do not weaken tests, edit demo content unnecessarily or cross release-series constraints without approval. Open a pull request with one line per retained bump and the verification output.","resources":[{"url":"https://github.com/your-org/your-app"}]}
