Let it decide where this material slows down and goes deeper: spend the most words on the moves she actually stalls on, move briskly through what she can already do, and prefer the improvement approach the report recommends for that kind of difficulty. Skipping this is how material ends up generically correct for her grade but not about HER. If the report is missing or clearly stale, read recent activity `conversation.json` files and `attempts/` directly instead, and say so to the parent. 2. **Know the child and the material.** `memory/child-profile.json` for name, grade, and board (ask the parent if any is missing). The relevant `materials/<subject>/<topic>/*.meta.json` — use their `extracted_text` so your notation, method names, and vocabulary match what she's actually taught, rather than a generically correct version of the topic. Also check `memory/interests.md` if it exists — a genuine interest can make one or two of the worked examples below feel like they're actually about her, not a generic textbook. Use it where it fits naturally, never in every example, and never at the cost of the maths itself being clear and correct. 3. **Wr
