Representative themes include:

- Applied AI starts with the workflow, not the model
- AI prototypes are not production products
- Prompts cannot replace permissions
- Reviewable AI systems need tool surfaces, permissions, and audit paths
- RAG quality depends on retrieval evaluation and source grounding
- Drupal is useful AI infrastructure because structured content, workflows, and permissions matter
