This is an assigned GSoC roadmap rather than a self-contained task, covering worker.py, wrangler.toml, src/scholar/ai_service.py, src/scholar/spaced_rep.py, and many public pages. Start by confirming the current A6–A9 scope with the assignee; completion would require implementing the unchecked schema, API, Durable Object, AI, and frontend items listed here.
